Description

Technical Field

[0001] This invention belongs to the field of large storage tank foundation and heating network pipeline support and adjustment technology, specifically relating to a method and system for adjusting the water injection of hot water storage tanks and the anti-settlement of heating network pipelines. Background Technology

[0002] With the continuous growth of installed capacity of new energy power generation, thermal power generating units are gradually undertaking the tasks of deep peak shaving and heat supply guarantee. In order to reduce the mutual constraints between power generation load and heating load, some thermal power plants have installed large atmospheric pressure hot water storage tanks to store hot water when the unit's heating capacity is surplus and release heat when the heating network load increases. Hot water storage tanks are usually connected to heat exchange equipment, circulating water systems and heating pipe networks through heating network pipelines. The settlement state of their foundations not only affects the verticality and structural stress of the tank itself, but also transmits it to the heating network pipelines through the tank's pipe openings, thereby affecting the pipeline stress, support load and the sealing state of the connection parts.

[0003] Large hot water storage tanks require gradual water filling after construction. The water load inside the tank increases continuously with the rising water level, characterized by large loads, a phased loading process, and a lag in foundation response. For soft soil, collapsible soil, loose strata, or foundations affected by freeze-thaw cycles, the water filling load easily causes overall settlement, local differential settlement, and long-term consolidation deformation. When the settlement varies across different circumferential areas of the tank, the tank is prone to tilting, and additional stresses can easily form between the tank bottom plate, tank walls, and foundation. Simultaneously, the tank inlets shift with the tank, while the connected heating network pipelines are constrained by fixed supports, elastic supports, and the thermal expansion of the pipelines. Inconsistent settlement between the tank and the pipelines can easily lead to increased inlet loads, increased local stress in the pipelines, and deviations in support loads from design conditions.

[0004] Existing hot water storage tanks typically employ ring foundations, reinforced concrete raft foundations, or composite foundations with subgrade treatment. These foundations primarily rely on their own stiffness to distribute the tank load. Once the foundation construction is completed, its load-bearing state is essentially fixed, making it difficult to proactively adjust the load-bearing capacity of different areas according to load changes at different water injection stages. When differential settlement occurs, engineering practices usually employ ground grouting, foundation reinforcement, local jacking, or the installation of pads to address the issue. These methods mostly need to be implemented after settlement has already occurred. The treatment process is easily constrained by the tank's operating status, construction space, and foundation structure, and it is also difficult to continuously verify the impact of the adjustment process on the settlement of adjacent areas and the tank's tilt.

[0005] Some existing leveling devices use hydraulic cylinders or hydraulic jacks to lift large equipment, but their control is usually based on the pressure of a single support point or the elevation of a single measuring point, lacking a definite relationship between the increase in water injection load and the target bearing capacity of each support point. When the elevation of a certain location is too low, increasing the pressure on the foundation in that area may further increase the foundation pressure if only the adjacent support points are pressurized; when the bearing capacity of a certain support point is too high, directly depressurizing may cause a sudden shift in load. Therefore, simply pressurizing or depressurizing according to the settlement is insufficient to distinguish between different states such as insufficient support point bearing capacity, excessive support point bearing capacity, continuous local foundation subsidence, and overall tank tilting, and it is also difficult to ensure that the adjustment process between multiple support points remains stable.

[0006] Furthermore, existing methods for controlling tank foundation settlement and adjusting heating network pipeline supports are typically performed separately. When adjusting the tank foundation, the displacement of the support points changes the position of the tank inlets; similarly, adjusting the pipeline supports changes the force exerted by the pipeline on the tank inlets. If there is a lack of unified adjustment criteria and execution sequence, situations may arise where tank settlement deviation decreases while pipeline stress increases, or repeated adjustments may occur due to simultaneous reverse movements of the hydraulic support points and pipeline supports. Current technology also lacks continuous verification of the settlement change rate, support bearing capacity change rate, and pipeline stress change rate after adjustment. In cases of sensor malfunction, single support point failure, insufficient support point stroke, or excessive pipeline stress, it is difficult to perform support point locking, fault isolation, load redistribution, and suspension of water injection.

[0007] Therefore, it is necessary to study a more complete anti-settlement adjustment scheme to address the mutual influence between the tank foundation and the heating network pipeline during the staged water injection process of hot water storage tanks. Summary of the Invention

[0008] The present invention aims to solve at least one of the technical problems existing in the prior art, and provides a method and system for adjusting the water injection of hot water storage tanks and the anti-settlement of heating network pipelines.

[0009] This invention provides a method for adjusting the water injection of a hot water storage tank and the anti-settlement of the heating network pipeline, comprising the following steps: S1: Obtain operating parameters during the water filling process of the hot water storage tank; S2: Determine the water injection load increment for the current water injection stage based on the operating parameters, distribute the water injection load increment according to the arrangement position of each hydraulic self-locking support, and superimpose it with the current bearing capacity of each hydraulic self-locking support to obtain the target bearing capacity of each hydraulic self-locking support. S3: Based on the deviation between the current bearing capacity and the target bearing capacity of each hydraulic self-locking fulcrum, as well as the tank settlement, displacement and stress of the heating network pipeline in the operating parameters, determine the hydraulic self-locking fulcrum to be adjusted and the fulcrum adjustment amount, and determine the pipeline support and support compensation amount to be adjusted. S4: Adjust the hydraulic self-locking fulcrum to be adjusted according to the fulcrum adjustment amount, and adjust the pipe support to be adjusted according to the support compensation amount. After the bearing capacity of each hydraulic self-locking fulcrum, the tank settlement and the stress of the heat pipe pipeline meet the stability conditions during continuous monitoring, the operating parameters are reacquired. S5: Verify the adjustment results: If the verification results meet the control requirements of the current water injection stage, continue water injection and enter the next water injection stage; if the verification results do not meet the control requirements, repeat steps S2-S5 according to the newly acquired operating parameters until the verification results meet the control requirements of the current water injection stage.

[0010] Furthermore, the incremental water injection load is determined based on the current water level, the target water level for this stage, the density of water, and the tank bottom area. Then, based on the zonal force relationship of the zoned bearing raft, the incremental water injection load is distributed to the current bearing capacity of each hydraulic self-locking support point according to vertical force balance and moment balance, thereby determining the target bearing capacity of each hydraulic self-locking support point.

[0011] Specifically, the operating parameters include water level, fulcrum pressure, fulcrum displacement, tank settlement, tank tilt, relative displacement between the tank inlet and the monitoring position of the adjacent pipeline, and pipeline stress; when the hydraulic self-locking fulcrum is in a hydraulic load-bearing state, the current load-bearing capacity is determined according to the fulcrum pressure; each hydraulic self-locking fulcrum is divided into multiple fulcrum groups in the circumferential direction, and each fulcrum group is associated with the tank settlement monitoring position in the same circumferential area, and each tank inlet is associated with the adjacent fulcrum group, pipeline monitoring position, and pipeline support.

[0012] Specifically, based on the settlement amount of each tank settlement monitoring position, the settlement difference between adjacent tank settlement monitoring positions, and the tank tilt amount, the settlement deviation area and tank tilt direction are determined; the bearing capacity deviation is determined based on the difference between the current bearing capacity and the target bearing capacity; the relative displacement and the pipeline stress are compared with their respective control limits to determine whether the pipeline supports need to be adjusted.

[0013] Preferably, based on the settlement deviation area, the tank tilt direction, and the bearing capacity deviation, an inner ring hydraulic self-locking fulcrum and an outer ring hydraulic self-locking fulcrum located in the same circumferential area are selected to form a fulcrum group to be adjusted; When the elevation of the tank area corresponding to the fulcrum group to be adjusted is too low, and the current bearing capacity of the fulcrum group to be adjusted is lower than the target bearing capacity, the fulcrum group to be adjusted is pressurized; when the elevation of the tank area is too high and the current bearing capacity is higher than the target bearing capacity, the load is first borne by the adjacent fulcrum group, and then the fulcrum group to be adjusted is depressurized; when the fulcrum adjustment direction determined according to the elevation deviation is inconsistent with the fulcrum adjustment direction determined according to the bearing capacity deviation, the state of the fulcrum group to be adjusted is maintained, and the load is redistributed through the adjacent fulcrum group. The single adjustment amount, adjustment rate, and bearing capacity difference between adjacent hydraulic self-locking fulcrums of the fulcrum group to be adjusted shall not exceed their respective adjustment limits.

[0014] Specifically, before water injection, each of the hydraulic self-locking fulcrums was tested and adjusted, and the relative displacement of the tank opening and the stress of the pipeline caused by the adjustment of the fulcrum were recorded. When it is expected that adjusting the fulcrum will increase the displacement deviation of the heating network pipeline or increase the stress of the pipeline, first adjust the support of the pipeline to be adjusted, and then adjust the hydraulic self-locking fulcrum to be adjusted; when it is expected that adjusting the fulcrum will not increase the displacement deviation or increase the stress of the pipeline, first adjust the hydraulic self-locking fulcrum to be adjusted, and then adjust the support of the pipeline to be adjusted. After each adjustment, the hydraulic self-locking fulcrum to be adjusted is locked and the current water level is maintained; when the tank settling rate, the fulcrum bearing capacity change rate, and the pipeline stress change rate do not exceed their respective stable thresholds during continuous monitoring, the bearing capacity and settlement response are determined to be stable.

[0015] Furthermore, when the detection data is abnormal, the locking state of each hydraulic self-locking fulcrum is maintained and water injection is suspended; when the hydraulic self-locking fulcrum fails, the locking state of the remaining hydraulic self-locking fulcrums is maintained, the faulty hydraulic self-locking fulcrum is isolated and water injection is suspended, and when the load-bearing capacity and remaining stroke of the adjacent hydraulic self-locking fulcrums meet the safety requirements, the target load-bearing capacity of each hydraulic self-locking fulcrum is redistributed. After the hot water storage tank reaches full water and completes the verification, it enters a long-term monitoring state. When the tank settles, the heating network pipeline shifts, or the pipeline stress reaches the compensation condition, the fulcrum adjustment amount and the support compensation amount are re-determined, the selected hydraulic self-locking fulcrum and pipeline support are adjusted, and the hydraulic self-locking fulcrum is locked after the adjustment result meets the full water operation control requirements.

[0016] Another aspect of the present invention provides a hot water storage tank water injection and heating network pipeline anti-settlement adjustment system, comprising: Hot water storage tank; A water injection control valve is installed on the water injection pipeline connected to the hot water storage tank; A multi-layer composite cushion layer is installed on the foundation; Multiple hydraulic self-locking fulcrums are arranged in sections on the multi-layer composite pad and distributed along the circumference of the hot water storage tank; A partitioned support raft is disposed between the plurality of hydraulic self-locking fulcrums and the hot water storage tank, for supporting the hot water storage tank; The heating network pipe is connected to the tank opening of the hot water storage tank; A pipeline support assembly is provided along the heating network pipeline to support the heating network pipeline and adjust the support state of the heating network pipeline. The detection components are respectively installed in the hot water storage tank, the hydraulic self-locking fulcrum, and the heating network pipeline, and are used to detect the water filling and settling status of the hot water storage tank, the load-bearing status of the hydraulic self-locking fulcrum, and the displacement and stress of the heating network pipeline; and The control unit is connected to the water injection control valve, the hydraulic self-locking fulcrum, the pipeline cooperative support assembly, and the detection assembly, respectively. It is used to determine the water injection load increment, target bearing capacity, fulcrum adjustment amount, and support compensation amount of the current water injection stage based on the detection results of the detection assembly, control the hydraulic self-locking fulcrum and the pipeline cooperative support assembly to adjust, and open the water injection control valve when the adjustment result meets the control requirements of the current water injection stage; otherwise, it keeps the water injection control valve closed and continues to adjust.

[0017] Furthermore, the partitioned support raft plate includes a central area, an outer ring area surrounding the central area, and radial reinforcing ribs connecting the central area and the outer ring area, wherein the thickness of the outer ring area is greater than the thickness of the central area; The plurality of hydraulic self-locking pivots include an inner ring hydraulic self-locking pivot located below the central area and an outer ring hydraulic self-locking pivot located below the outer ring area; each hydraulic self-locking pivot includes a hydraulic cylinder, a hydraulic lock and a mechanical lock, and is connected to a hydraulic source through an independent hydraulic branch; The multi-layer composite cushion layer includes an impermeable isolation layer, a stress diffusion layer, an elastic pressure equalization layer and a high-strength wear-resistant layer arranged sequentially from the foundation upwards, and multiple hydraulic self-locking fulcrums are supported on the high-strength wear-resistant layer.

[0018] Specifically, the pipeline co-support assembly includes a flexible support and an adjusting member connected to the flexible support. The adjusting member is used to change the support elevation of the flexible support to adjust the elastic displacement and support force of the flexible support. The detection components include a water level detection device, a settlement detection device, and an inclination detection device installed in the hot water storage tank; a pressure detection device and a displacement detection device installed in the hydraulic self-locking fulcrum; and a pipe displacement detection device and a pipe stress detection device installed in the heating network pipeline. Each of the independent hydraulic branches is equipped with an isolation valve. When the pressure or displacement of the hydraulic self-locking fulcrum is abnormal, the control unit stops the hydraulic adjustment of the corresponding hydraulic self-locking fulcrum and closes the isolation valve on its independent hydraulic branch. When the mechanical lock is already locked, it remains locked. When the mechanical lock is not yet locked and the hydraulic cylinder still has the capacity to bear load, the position of the hydraulic self-locking fulcrum is maintained in the order of first closing the hydraulic lock and then driving the mechanical lock to lock.

[0019] The beneficial effects of this invention are as follows: This invention adjusts the bearing state of each hydraulic self-locking support point according to the load increment generated by staged water injection, and coordinates the adjustment of the hydraulic self-locking support points and pipe supports in conjunction with tank settlement, tilt, pipe displacement, and pipe stress. Through the cooperation of variable stiffness raft plates, inner and outer ring hydraulic self-locking support points, and multi-layer composite pads, the load transfer of the tank and the stress on the foundation are improved. Through stability confirmation, closed-loop verification, fault isolation, and controlled compensation after full water filling, the adverse effects of differential settlement on the operation of the tank, tank inlets, and heating network pipelines are reduced.

Figure 2 This is a connection block diagram of a hot water storage tank water injection and heating network pipeline anti-settlement adjustment system according to a specific embodiment of the present invention. Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown in the figure, a method for adjusting the water injection of a hot water storage tank and the anti-settlement of a heating network pipeline provided by a specific embodiment of the present invention includes the following steps: S1: Obtain the operating parameters during the water filling process of the hot water storage tank.

[0023] The operating parameters are used to reflect the current water injection load, the bearing status of each hydraulic self-locking support, the settlement status of the hot water storage tank, and the displacement and stress status of the heating network pipeline.

[0024] S2: Determine the water injection load increment for the current water injection stage based on the operating parameters, distribute the water injection load increment according to the arrangement position of each hydraulic self-locking support, and superimpose the load increment allocated to each hydraulic self-locking support with its current bearing capacity to obtain the target bearing capacity of each hydraulic self-locking support.

[0025] S3: Based on the deviation between the current bearing capacity and the target bearing capacity of each hydraulic self-locking fulcrum, the tank settlement, and the displacement and stress of the heating network pipeline, determine the hydraulic self-locking fulcrum to be adjusted and the fulcrum adjustment amount, and determine the pipeline support and hanger to be adjusted and the support and hanger compensation amount.

[0026] S4: Maintain the current water level, adjust the hydraulic self-locking fulcrum to be adjusted according to the fulcrum adjustment amount, and adjust the pipe support to be adjusted according to the support compensation amount.

[0027] The fulcrum adjustment amount includes at least one of fulcrum pressure adjustment amount and fulcrum displacement adjustment amount, and the support and hanger compensation amount includes at least one of support elevation adjustment amount, elastic displacement adjustment amount, and support force adjustment amount. The adjustment is performed in stages and in small increments. After each adjustment is completed, the current adjustment state is maintained to avoid sudden changes in fulcrum load causing localized stress concentration in the zoned load-bearing raft or rapid stress changes in the heating network pipeline.

[0028] S5: After the bearing capacity of each hydraulic self-locking fulcrum, tank settlement, and pipeline stress meet the stability conditions during continuous monitoring, the operating parameters are reacquired, and the adjustment results are verified. If the verification results meet the control requirements of the current water injection stage, water injection continues and the next water injection stage begins. If the verification results do not meet the control requirements, the hydraulic self-locking fulcrum to be adjusted, the fulcrum adjustment amount, the pipeline support and hanger to be adjusted, and the support and hanger compensation amount are re-determined based on the reacquired operating parameters, and the adjustment and verification are repeated. The stability conditions refer to the fact that the tank settlement rate, the change rate of the bearing capacity of the hydraulic self-locking fulcrum, and the change rate of pipeline stress do not exceed their respective stability thresholds during continuous monitoring.

[0029] In one embodiment, the control requirements for the current water injection stage include at least the following: the bearing capacity deviation of each hydraulic self-locking fulcrum does not exceed the corresponding bearing capacity deviation limit; the differential settlement and tilt of the tank do not exceed the corresponding settlement control limit; the relative displacement between the tank inlet and the monitoring position of the adjacent pipeline does not exceed the displacement control limit; and the pipeline stress does not exceed the pipeline stress control limit. These limits are determined based on the structural design requirements of the hot water storage tank, the bearing capacity of the zoned load-bearing raft, the foundation deformation requirements, the adjustment capability of the hydraulic self-locking fulcrum, and the allowable displacement and allowable stress of the heating network pipeline.

[0030] Specifically, this method combines the feedforward distribution of water injection load with the feedback adjustment of tank settlement, pipeline displacement, and pipeline stress. The incremental water injection load is used to predetermine the target bearing capacity of each hydraulic self-locking support, and the adjusted settlement and stress response are used to correct the next support adjustment amount and support compensation amount, thus forming a cyclical process of graded water injection, support adjustment, pipeline compensation, stability confirmation, and result verification.

[0031] Based on the above basic implementation method, the water injection load increment is determined according to the current water level, the target water level of the current water injection stage, the density of water, and the effective area of ​​the tank bottom.

[0032] For hot water storage tanks where the cross-sectional area remains constant along the height, the increment of the water injection load is determined according to the following formula:

[0033] in, This represents the increase in water injection load during the current water injection phase. The density of water, The effective area of ​​the tank bottom. This is the target water level for the current water injection phase. The current water level is indicated by the specific gravity of water, which refers to the weight of a unit volume of water, also known as unit weight or volumetric weight.

[0034] When the internal structure of the hot water storage tank affects the effective water storage area, the effective area of ​​the tank bottom is determined based on the actual water storage volume between the current water level and the target water level, and the nominal bottom area of ​​the tank is no longer used directly.

[0035] Furthermore, based on the stress relationship between the central area, outer ring area and radial reinforcing ribs of the zoned bearing raft, the incremental water injection load is distributed to the inner ring hydraulic self-locking support and the outer ring hydraulic self-locking support.

[0036] For example, let the first The equivalent vertical stiffness of each hydraulic self-locking fulcrum is: Its coordinates relative to the center of the raft are The load increment is determined according to the following formula:

[0037] in, , and Determined based on the sum of all support load increments and the moment equilibrium condition about the two horizontal axes. Equivalent vertical stiffness. The stiffness is determined based on the support stiffness, raft slab zone stiffness, and local foundation stiffness. This explains why the inner and outer ring supports are not simply evenly distributed.

[0038] The distribution process ensures that the sum of the load increments allocated to all supports equals the water injection load increment of this stage, and that the resultant moment formed by the load increments allocated to each support is balanced with the moment formed by the new load in this stage. When the new water load in this stage is symmetrically distributed relative to the center of the tank, the horizontal eccentric moment formed by the new water load is treated as zero. When the tank pipe load, the force of the heating network pipeline, or other additional loads change in this stage, the corresponding vertical component force and moment are included in the support load distribution.

[0039] Furthermore, the outer ring hydraulic self-locking supports primarily bear the forces transmitted through the outer ring area, including the tank wall's own weight, the water load near the tank wall, and the additional load from the tank pipe openings. The inner ring hydraulic self-locking supports primarily bear the forces transmitted through the central area, including the water load from the middle of the tank bottom and above. Radial reinforcing ribs connect the central and outer ring areas, transferring shear force and bending moment between the two regions. Therefore, the load distribution at each support is not simply determined by the average number of supports, but rather by considering the support locations, the raft slab's zonal stiffness, and the location of the upper load.

[0040] The target bearing capacity of each hydraulic self-locking support point is determined according to the following formula:

[0041] in, For the first The target load-bearing capacity of each hydraulic self-locking fulcrum This represents the current load-bearing capacity of the hydraulic self-locking fulcrum. This is the load increment allocated to the hydraulic self-locking fulcrum in this stage.

[0042] Therefore, the target bearing capacity is not to redistribute all the water-filled load in this stage, but to add the load increment that should be borne in this stage to the current bearing state of each support.

[0043] In one specific implementation, the operating parameters include water level, fulcrum pressure, fulcrum displacement, tank settlement, tank tilt, relative displacement between the tank inlet and the monitoring location of the adjacent pipeline, and pipeline stress.

[0044] The water level is used to determine the current water injection stage and the increment of the water injection load; the fulcrum pressure is used to reflect the bearing capacity of the hydraulic cylinder under hydraulic load; the fulcrum displacement is used to determine the actual adjustment amount and remaining adjustment stroke of the hydraulic self-locking fulcrum; the tank settlement amount and tank tilt amount are used to determine the tank settlement deviation area and tilt direction; the relative displacement and pipeline stress are used to determine whether the tank settlement has an adverse effect on the tank inlet and the heating network pipeline.

[0045] When the hydraulic self-locking fulcrum is under hydraulic load, the current load capacity is determined based on the fulcrum pressure, the effective bearing area of ​​the hydraulic cylinder, and the fulcrum calibration results. The fulcrum calibration results are used to correct for the influence of hydraulic cylinder sealing friction, hydraulic circuit back pressure, and structural differences among the fulcrums on the relationship between pressure and load capacity.

[0046] When the mechanical lock is under load, the total load-bearing capacity of the fulcrum is not determined directly based on the current pressure of the hydraulic cylinder. When readjustment of the hydraulic self-locking fulcrum is required, the hydraulic cylinder is first gradually built up to a pressure adapted to the load state before locking. Once the hydraulic cylinder bears the upper load and the fulcrum displacement remains stable, the mechanical lock is released. The fulcrum pressure obtained after the mechanical lock is released is used to determine the current load-bearing capacity before this adjustment. This process prevents sudden fulcrum retraction or sudden load changes when the mechanical lock is released.

[0047] In this embodiment, multiple tank monitoring areas are divided along the circumference of the hot water storage tank. Each tank monitoring area includes at least one tank settlement monitoring position and an inner and outer hydraulic self-locking fulcrum adjacent to that tank settlement monitoring position. The inner and outer hydraulic self-locking fulcrums located in the same tank monitoring area form a fulcrum group.

[0048] For tank monitoring areas with tank inlets, establish a correspondence between the tank inlets and adjacent support groups, the pipeline monitoring locations outside the tank inlets, and the pipeline supports that support this section of the heating network pipeline. For tank monitoring areas without tank inlets, only establish a correspondence between support groups and tank settlement monitoring locations; it is not required that each support group correspond to a tank inlet.

[0049] Furthermore, all hydraulic self-locking fulcrums, tank settlement monitoring locations, tank inlets, pipeline monitoring locations, and pipeline supports are uniformly numbered. The control unit uses these numbers to determine the tank areas, tank inlets, and pipeline supports that require focused monitoring after adjusting a particular fulcrum, avoiding the use of monitoring results from distant locations with weak force connections to determine the adjustment amount for that fulcrum.

[0050] In another specific embodiment, the settlement deviation area and the tank tilt direction are determined based on the tank settlement amount at each tank settlement monitoring location, the settlement difference between adjacent tank settlement monitoring locations, and the tank tilt amount.

[0051] The tank settlement is determined based on the baseline elevation before water injection or the elevation after stabilization in the previous water injection stage. The average tank settlement is calculated based on the settlement at each monitoring location, and the settlement at each monitoring location is compared with this average settlement. Areas with settlement greater than the average settlement are defined as relatively low elevation areas, and areas with settlement less than the average settlement are defined as relatively high elevation areas.

[0052] The tank tilt direction is determined by the elevation changes of each tank settlement monitoring location and the tank tilt amount. When the tilt direction reflected by the settlement monitoring results and the tilt angle detection results is consistent, the set of fulcrums to be adjusted is selected according to that direction; when the two types of detection results are inconsistent, the fulcrum adjustment is suspended, and the settlement detection pieces and tilt angle detection pieces are checked. The tank lifting or lowering action is not performed based on a single detection result.

[0053] In this embodiment, overall uniform settlement and local non-uniform settlement are handled separately. When the settlement difference and tank tilt between each monitoring location meet the control requirements, but all monitoring locations show similar overall settlement, differential leveling is not performed on individual support point groups. Instead, the need for overall compensation is determined based on the overall tank elevation, the relative displacement of the tank pipe openings, and the stress of the heating network pipeline. When the settlement difference between one or more monitoring locations and adjacent monitoring locations exceeds the corresponding limit, the circumferential area where the monitoring location is located is defined as the settlement deviation area.

[0054] The bearing capacity deviation is determined by the difference between the current bearing capacity and the target bearing capacity of each hydraulic self-locking fulcrum. When the current bearing capacity is lower than the target bearing capacity, the bearing capacity deviation reflects that the fulcrum is underloaded; when the current bearing capacity is higher than the target bearing capacity, the bearing capacity deviation reflects that the fulcrum is overloaded.

[0055] Specifically, the relative displacement between the tank inlet and the monitoring location of the adjacent pipeline, and the pipeline stress are compared with their respective control limits. When the relative displacement reaches the displacement compensation trigger value or the pipeline stress reaches the stress compensation trigger value, it is determined that the corresponding pipeline supports need to be adjusted.

[0056] The benchmark for comparing pipeline stress is determined based on the current temperature and operating conditions of the heating network pipeline. Stress changes caused by normal thermal expansion and contraction and conforming to the pipeline design displacement law are not used as the sole basis for settlement compensation; additional stress caused by the relative displacement between the tank inlet and the monitoring position of the adjacent pipeline is used as the basis for judging the coordinated adjustment of the fulcrum and pipeline supports.

[0057] In another specific embodiment, based on the settlement deviation area, the tank tilt direction and the bearing capacity deviation, the inner ring hydraulic self-locking fulcrum and the outer ring hydraulic self-locking fulcrum located in the same circumferential area are selected to form the fulcrum group to be adjusted.

[0058] When the elevation of the tank area corresponding to the fulcrum group to be adjusted is too low and the current bearing capacity is lower than the target bearing capacity, the fulcrum group is pressurized to make the hydraulic cylinder extend slightly and increase the support of the area.

[0059] When the elevation of the tank area corresponding to the fulcrum group to be adjusted is too high and the current bearing capacity is higher than the target bearing capacity, first slightly increase the pressure on the adjacent fulcrum groups so that they bear part of the load of the area to be adjusted; after confirming that the bearing capacity and displacement of the adjacent fulcrum groups are within the allowable range, then depressurize and adjust the fulcrum group to be adjusted, so that the hydraulic cylinder retracts in a controlled manner. Direct unloading is not used during the depressurization process to avoid sudden drops in the local elevation of the raft deck.

[0060] When the tank tilts, differential adjustment is performed on the support groups on the low and high elevation sides. The low elevation side primarily experiences pressure-increasing expansion, while the high elevation side primarily experiences pressure-relieving contraction after the adjacent support group bears the load. The tank tilt is re-measured after each differential adjustment, and multiple unchecked cumulative adjustments are not performed consecutively.

[0061] For settlement deviation areas near the tank wall and tank pipe openings, the bearing condition of the outer ring hydraulic self-locking support should be determined first, and then the adjustment amount of the inner ring hydraulic self-locking support should be determined. For settlement deviation in the corresponding area of ​​the middle of the tank bottom, the bearing condition of the inner ring hydraulic self-locking support should be determined first, and the local rotation of the raft plate should be restricted by the outer ring hydraulic self-locking support in the same circumferential area.

[0062] When the required adjustment directions for elevation deviation and bearing capacity deviation are consistent, make small adjustments directly in the corresponding directions. When the required adjustment directions for elevation deviation and bearing capacity deviation are inconsistent, maintain the current position of the support group, first redistribute the load through adjacent support groups, and then re-determine the adjustment direction after the bearing capacity deviation decreases.

[0063] Furthermore, for example, if the elevation of the tank area is too low but the bearing capacity of the corresponding support point is higher than the target bearing capacity, the pressure is not increased directly. Instead, the bearing capacity of the adjacent support point group is first increased, so that part of the load of the support point group to be adjusted is transferred to the adjacent support point group, and then it is determined whether to perform extension adjustment. If the elevation of the tank area is too high but the bearing capacity of the corresponding support point is lower than the target bearing capacity, the pressure is not released directly. Instead, the adjacent support point group is adjusted first to prevent further loss of load at that support point.

[0064] Specifically, the single-point adjustment amount is determined based on the tank's allowable settlement difference, the remaining stroke of the hydraulic cylinder, the local stress on the raft slab, and the allowable displacement of the heating network pipeline; the adjustment rate of the support is determined based on the hydraulic cylinder's response speed, the raft slab's stiffness, and the foundation's deformation response time; the limit for the bearing capacity difference between adjacent supports is determined based on the results of the raft slab's bending, shear, and local bearing pressure calculations. These limits are determined during the engineering design phase and stored in the control unit, and fixed, universal values ​​are not used without prior verification.

[0065] In another specific embodiment, a small-scale trial adjustment is performed on each hydraulic self-locking fulcrum before water injection. During the trial adjustment, the hot water storage tank is kept in an unloaded state or a low water level state. Controlled pressure increments or displacement increments are applied to the selected hydraulic self-locking fulcrums in sequence, and the elevation changes, tank tilt changes, relative displacement changes of tank pipe openings, and pipe stress changes of the corresponding tank settlement monitoring positions are recorded.

[0066] Based on the trial adjustment results, the influence of unit pressure change or unit displacement change of each hydraulic self-locking support point on the local elevation of the tank, tank tilt, relative displacement of the tank pipe opening, and pipeline stress was determined. During the subsequent water injection stage, the aforementioned influence relationship was corrected based on the actual support point adjustment and its resulting actual response, to adapt to the increased water injection load, changes in foundation stiffness, and differences in the response of each support point.

[0067] When it is expected that adjusting the fulcrum will increase the displacement deviation of the heating network pipeline or increase the pipeline stress, first adjust the corresponding pipeline support and hanger to make the heating network pipeline generate a compensating displacement in advance that is adapted to the expected pipe displacement direction, and then adjust the hydraulic self-locking fulcrum.

[0068] When it is expected that adjusting the fulcrum will not increase the displacement deviation of the heating network pipeline and will not increase the pipeline stress, first adjust the hydraulic self-locking fulcrum, and then adjust the pipeline support and hanger according to the actual relative displacement of the pipe opening and the pipeline stress after adjustment.

[0069] When tank leveling requirements conflict with pipeline stress control requirements, first ensure that the hot water storage tank, zoned load-bearing raft, and hydraulic self-locking supports do not exceed the structural load-bearing limits; on the basis of ensuring structural load-bearing safety, prioritize limiting the relative displacement of the tank pipe openings and pipeline stress, then reduce tank tilt and differential settlement, and finally adjust the load-bearing capacity deviation between each hydraulic self-locking support.

[0070] Furthermore, after adjusting the pipe supports and hangers, the pipe displacement and stress are re-acquired; after adjusting the hydraulic self-locking fulcrum, the tank settlement, tilt, fulcrum bearing capacity, pipe displacement, and pipe stress are re-acquired. The control unit does not simultaneously issue adjustment commands in opposite directions and with mutually canceling effects to the hydraulic self-locking fulcrum and pipe supports and hangers in the same area.

[0071] After each adjustment, close the regulating valve of the hydraulic branch and maintain the hydraulic cylinder state using a hydraulic lock, then use a mechanical lock to limit the displacement of the hydraulic cylinder. Maintain the current water level during adjustment and stabilization observation, and do not continue to increase the water injection load.

[0072] Specifically, the load-bearing and settlement response is considered stable when the tank settlement rate, the rate of change of the bearing capacity of the support, and the rate of change of the pipeline stress all do not exceed their respective stability thresholds during continuous monitoring. The continuous monitoring period is determined based on the deformation response time of the foundation soil, the sensor sampling cycle, and the load increment during the water injection stage; the stability threshold is determined based on the detection accuracy, measurement fluctuations, and allowable engineering deviations.

[0073] In another specific embodiment, the control unit performs a validity check on the operating parameters. The validity check includes checking whether the detected value exceeds the detection range, whether there are abnormal jumps between adjacent sampling times, whether the detected value remains unchanged for a long time, and whether different detection results within the same area contradict each other.

[0074] When the detection data is abnormal and cannot be eliminated by re-collection, maintain the locked state of each hydraulic self-locking fulcrum, close the water injection control valve and issue an alarm, and do not perform fulcrum adjustment or pipeline support adjustment based on the abnormal data.

[0075] When a hydraulic self-locking pivot experiences abnormal pressure, abnormal displacement, hydraulic leakage, or fails to respond to adjustment commands as expected, the isolation valve of the independent hydraulic branch containing that pivot is closed, maintaining the locked state of the remaining hydraulic self-locking pivots and suspending water injection. If the mechanical lock of the faulty pivot still has the ability to maintain its position, the mechanical lock will maintain the pivot's position; if the faulty pivot cannot maintain its load-bearing state, the load borne by the faulty pivot will be gradually transferred to the adjacent pivots based on their remaining load-bearing capacity and remaining stroke.

[0076] The target load-bearing capacity is redistributed only when the load-bearing capacity of adjacent hydraulic self-locking fulcrums, the remaining stroke, and the local stress on the zoned load-bearing raft all meet safety requirements. If any condition is not met, water injection stops, and the system remains in alarm mode.

[0077] Furthermore, if the pipe supports become stuck, the adjustment stroke is insufficient, or the pipe stress does not decrease as expected after adjustment, stop adjusting the support points in the area corresponding to the pipe opening on the tank, and maintain the current water level and the locked support points. If the pipe stress continues to rise or reaches the safety limit, close the water injection control valve and check the pipe support status.

[0078] When a communication failure occurs between the control unit and the detection component or actuator, the water injection control valve enters the closed state, the hydraulic lock maintains the hydraulic cylinder pressure, the mechanical lock maintains the hydraulic self-locking fulcrum position, and the pipe supports maintain the support state before the failure.

[0079] Once the hot water storage tank reaches full water and the verification results meet the full water operation control requirements, all hydraulic self-locking fulcrums are locked and the system enters long-term monitoring mode. During long-term monitoring, the control unit periodically acquires data on tank settlement, tank tilt, fulcrum pressure, fulcrum displacement, relative displacement of tank pipe openings, and pipe stress.

[0080] Specifically, when tank settlement, heating network pipeline displacement, or pipeline stress reaches the compensation trigger condition, and the corresponding changes continue to develop during continuous monitoring, the control unit re-determines the fulcrum adjustment amount and the support compensation amount. Under the conditions that the water level in the hot water storage tank remains stable, the heating network pipeline is not in a rapid temperature change phase, and the fulcrum to be adjusted and adjacent fulcrums have adjustment margins, the hydraulic cylinder first assumes the fulcrum load, then the mechanical lock is released in a controlled manner, and a small adjustment is performed.

[0081] After long-term compensation is completed, the tank settlement, tank tilt, fulcrum bearing condition, pipeline displacement, and pipeline stress are re-inspected. Once the verification results meet the full-water operation control requirements and the response is stable, the hydraulic lock and mechanical lock are reactivated. During long-term operation, the mechanical lock maintains the adjusted position of the hydraulic self-locking fulcrum; any continued settlement of the foundation is handled through long-term monitoring and controlled compensation. The mechanical lock includes a fixed base, a locking nut, a locking drive component, a transmission mechanism, and a locking status detection component. The fixed base is located at the upper end of the cylinder body of the hydraulic cylinder. The piston rod of the hydraulic cylinder has an external thread section, and the locking nut is threadedly connected to this external thread section. The locking drive component is connected to the locking nut via the transmission mechanism and is used to drive the locking nut to move along the external thread section. The locking status detection component is located between the fixed base and the locking nut and is connected to the control unit, used to detect whether the locking nut has reached the locked position.

[0082] After the hydraulic self-locking fulcrum is adjusted, the control unit first controls the hydraulic lock to close, maintaining the current pressure and piston rod position of the hydraulic cylinder, and then controls the locking drive to move the locking nut towards the fixed seat. Once the locking state detection device detects that the locking nut is in contact with the fixed seat, the control unit stops the locking drive, and the locking nut, through the fixed seat, restricts the piston rod from retracting, thus placing the hydraulic self-locking fulcrum in a mechanically locked state.

[0083] When the hydraulic self-locking fulcrum needs to be readjusted, the control unit first controls the hydraulic cylinder to restore the hydraulic pressure to a level appropriate for the current load-bearing capacity, allowing the hydraulic cylinder to bear the load held by the mechanical lock; then, it controls the locking drive to reverse its movement, causing the locking nut to disengage from the fixed seat. After the locking status detection device confirms that the mechanical lock is released, the control unit controls the hydraulic lock to open and adjusts the pressure of the hydraulic cylinder by increasing or decreasing the pressure.

[0084] The transmission mechanism employs a reduction transmission structure with reverse self-locking function. In the event of a power outage or a failure of the locking drive component, the transmission mechanism restricts the reverse rotation of the locking nut, keeping the mechanical lock in a locked state; the control unit stops the adjustment of the corresponding hydraulic self-locking fulcrum, closes the isolation valve on its independent hydraulic branch, and issues a fault signal.

[0085] In one specific embodiment, a hot water storage tank water injection and heating network pipeline anti-settlement adjustment system is provided, including a hot water storage tank, a water injection control valve, a multi-layer composite pad, multiple hydraulic self-locking fulcrums, a zoned load-bearing raft, a heating network pipeline, a pipeline cooperative support assembly, a detection assembly, and a control unit.

[0086] The water injection control valve is located on the water injection pipeline connected to the hot water storage tank and is used to control the opening and closing of the water injection pipeline. The water injection control valve adopts a drive structure with a power failure shut-off state, so that water injection into the hot water storage tank will stop when the system loses power, communication is interrupted, or the control unit issues a stop water injection command.

[0087] A multi-layer composite cushion layer is installed on the treated foundation. Multiple hydraulic self-locking supports are arranged in sections along the circumference of the hot water storage tank. The lower end of each hydraulic self-locking support is supported by the high-strength, wear-resistant layer of the multi-layer composite cushion layer, and the upper end of each hydraulic self-locking support is connected to the support mounting part of the section bearing raft. The section bearing raft is supported by multiple hydraulic self-locking supports, and the hot water storage tank is installed on the section bearing raft.

[0088] This forms a load-bearing hierarchy consisting of the foundation, multi-layer composite cushion layer, hydraulic self-locking supports, zoned load-bearing raft, and hot water storage tank, arranged sequentially upwards. The vertical load generated by the hot water storage tank and its internal water is first transferred to the zoned load-bearing raft, then transferred to the multi-layer composite cushion layer by multiple hydraulic self-locking supports, and finally diffused to the foundation through the multi-layer composite cushion layer.

[0089] The heating network pipeline is connected to the tank opening of the hot water storage tank. A pipeline support assembly is installed along the heating network pipeline to support it and adjusts the support elevation and force according to control unit commands.

[0090] The detection components are respectively installed in the hot water storage tank, the hydraulic self-locking fulcrum, and the heating network pipeline to detect the water filling and settling status of the hot water storage tank, the load-bearing status of the hydraulic self-locking fulcrum, and the displacement and stress of the heating network pipeline.

[0091] The control unit is connected to the water injection control valve, the hydraulic self-locking fulcrum, the pipeline cooperative support assembly, and the detection assembly. Based on the detection results from the detection assembly, the control unit determines the water injection load increment, the target bearing capacity of each hydraulic self-locking fulcrum, the fulcrum adjustment amount, and the support compensation amount for the current water injection stage, and controls the hydraulic self-locking fulcrum and the pipeline cooperative support assembly to make adjustments.

[0092] In this embodiment, after adjustment, the control unit keeps the water injection control valve closed and performs verification based on the newly acquired test results. If the verification result meets the control requirements of the current water injection stage, the control unit opens the water injection control valve to enter the next water injection stage; if the verification result does not meet the control requirements, the control unit continues to keep the water injection control valve closed and readjusts.

[0093] In one specific embodiment, the partitioned load-bearing raft includes a central region, an outer ring region surrounding the central region, and radial reinforcing ribs connecting the central region and the outer ring region, wherein the thickness of the outer ring region is greater than the thickness of the central region.

[0094] The loads on and near the tank wall of the hot water storage tank are mainly transferred to the outer ring area of ​​the zoned load-bearing raft, while the water loads in the middle of the tank bottom and above are mainly transferred to the central area. Vertical forces and bending moments generated at the tank inlets are transferred through the tank wall to the adjacent outer ring area and radial reinforcing ribs. The outer ring area is thickened to improve the bending, shear, and local pressure resistance of the tank wall's load-bearing areas. Radial reinforcing ribs are used to transfer bending moments and shear forces between the central and outer ring areas and to limit raft torsion caused by local settlement. Multiple hydraulic self-locking supports include an inner ring hydraulic self-locking support located below the central area and an outer ring hydraulic self-locking support located below the outer ring area. The inner and outer ring hydraulic self-locking supports are arranged at intervals along the circumference of the hot water storage tank, forming multiple support groups according to the circumferential regions.

[0095] Furthermore, each hydraulic self-locking pivot includes a hydraulic cylinder, a pressure detection element, a displacement detection element, a hydraulic lock, a mechanical lock, and a stroke limiting structure. The pressure detection element detects the hydraulic pressure of the hydraulic cylinder, the displacement detection element detects the extension and retraction displacement of the hydraulic cylinder, and the stroke limiting structure limits the maximum extension and maximum retraction positions of the hydraulic cylinder.

[0096] A hydraulic lock is installed in the inlet and outlet oil lines of the hydraulic cylinder to close the oil lines and maintain the hydraulic pressure after adjustment. A mechanical lock cooperates with the moving parts of the hydraulic cylinder to limit its displacement after the hydraulic cylinder reaches the target position. The hydraulic lock is used to maintain the hydraulic pressure after adjustment, while the mechanical lock is used to maintain the position in the event of power failure, pressure loss, or long-term operation.

[0097] Each hydraulic self-locking pivot is connected to the hydraulic source via an independent hydraulic branch. Each independent hydraulic branch is equipped with a pressure regulator, a reversing control, a hydraulic lock, and an isolation valve, allowing each hydraulic self-locking pivot to receive pressure increase, pressure holding, and pressure release commands separately. The inner and outer hydraulic self-locking pivots within the same pivot group receive group linkage commands, while different pivot groups maintain independent adjustment relationships.

[0098] Furthermore, the multi-layer composite cushion layer includes, in sequence from the foundation upwards, an impermeable isolation layer, a stress diffusion layer, an elastic pressure equalization layer, and a high-strength wear-resistant layer.

[0099] The impermeable isolation layer is used to block groundwater and capillary water and to separate the superstructure from the poor foundation soil; the stress diffusion layer is used to diffuse the concentrated load transmitted by the hydraulic self-locking fulcrum to a larger foundation area; the elastic equalizing layer is used to buffer local deformation and fulcrum pressure changes, and reduce the sudden change in stiffness between adjacent fulcrums; the high-strength wear-resistant layer forms the bearing support surface of the hydraulic self-locking fulcrum and limits the slippage and local wear at the bottom of the fulcrum.

[0100] A high-strength, wear-resistant layer forms a fulcrum mounting area at the corresponding position of each hydraulic self-locking fulcrum. The base of the hydraulic self-locking fulcrum is fixed to the fulcrum mounting area, and the top pressure bearing seat of the hydraulic self-locking fulcrum is connected to the fulcrum mounting part of the partition bearing raft plate.

[0101] In one specific implementation, the pipeline co-support assembly includes a flexible support bracket installed along the heating network pipeline and an adjusting member connected to the flexible support bracket.

[0102] The adjusting mechanism changes the installation elevation of the flexible support, causing the elastic element of the support to expand and contract accordingly, thereby adjusting the supporting force applied by the flexible support to the heating network pipeline. The adjusting mechanism adopts an electric screw adjusting structure, a hydraulic adjusting structure, or other adjusting structure with position holding function, and feeds back the actual adjusted position to the control unit.

[0103] When adjusting the support elevation, the control unit determines the change in support force based on the stiffness and actual elastic displacement of the elastic support. The adjusting component changes the installation elevation and elastic displacement of the elastic support, and the support force of the elastic support changes accordingly according to its load-displacement characteristics. For constant force spring supports, the target position of the adjusting component is determined based on its load-displacement characteristics; for variable force spring supports, the elastic displacement adjustment is determined based on the spring stiffness and the target support force.

[0104] The detection components include water level detection devices, settlement detection devices, and tilt detection devices installed in hot water storage tanks; pressure detection devices and displacement detection devices installed at hydraulic self-locking fulcrums; and pipe displacement detection devices and pipe stress detection devices installed in heating network pipelines.

[0105] Specifically, water level sensors are positioned to reflect the actual water level in the hot water storage tank. Settlement sensors are arranged circumferentially along the hot water storage tank or the zoned support raft, corresponding to the circumferential areas of each support group. Inclination sensors are positioned to reflect the overall tilt of the tank, and their detection directions include at least two intersecting horizontal directions.

[0106] Pipeline displacement detection devices are installed on the outside of the tank inlet and at locations where the displacement of the heating network pipeline is significant, to determine the relative displacement between the tank inlet and the monitoring location of adjacent pipelines. Pipeline stress detection devices are installed on pipe sections adjacent to the tank inlet, at bends, or at stress concentration locations, to detect stress changes caused by tank settlement and changes in pipeline support conditions.

[0107] Each independent hydraulic branch is equipped with an isolation valve. When the pressure or displacement of the hydraulic self-locking pivot is abnormal, the control unit closes the isolation valve connected to the hydraulic self-locking pivot that is malfunctioning, and controls the mechanical lock to maintain the position of the hydraulic self-locking pivot.

[0108] When the hydraulic lock can no longer maintain its hydraulic state due to pressure loss, the mechanical lock assumes the position holding function; when the mechanical lock is not in the locked position, the control unit does not allow the hydraulic branch containing the hydraulic cylinder to be completely depressurized. The status of the hydraulic lock, the status of the mechanical lock, and the displacement of the fulcrum are used together to determine whether the hydraulic self-locking fulcrum has completed safe locking.

[0109] Furthermore, the control unit includes functions for data acquisition, water injection stage determination, load determination, deviation judgment, fulcrum adjustment, pipeline compensation, stability verification, and fault protection. Water level detection results are used to determine the water injection stage and water injection load increment; fulcrum pressure and fulcrum displacement are used to determine the load-bearing state and adjustment margin; tank settlement and tilt are used to determine the area to be adjusted; pipeline displacement and pipeline stress are used to determine the support and hanger compensation requirements; and all detection results after adjustment are used for stability judgment and verification. Therefore, all parameters obtained by the detection components participate in subsequent judgments or verifications, and the fulcrum adjustment and support and hanger compensation amounts generated by the control unit are executed by the corresponding execution structures and re-detected after execution.

[0110] In one specific implementation, the hot water storage tank is divided into multiple monitoring zones along its circumference, the first... The monitoring area includes the inner hydraulic self-locking fulcrum. Outer ring hydraulic self-locking fulcrum Tank Settlement Monitoring Location And the component of the tilt angle detection result in that area. For monitoring areas with tank nozzles, this also includes the monitoring locations of pipelines adjacent to the tank nozzles. and pipe supports .

[0111] Before each water injection, the control unit performs a safety check. This safety check includes: checking whether the water level, settlement, tilt, pressure, displacement, pipe displacement, and pipe stress sensors are within their normal ranges; checking whether the hydraulic and mechanical locks at each hydraulic self-locking point can lock and unlock; checking whether the isolation valves of each independent hydraulic branch are in their set positions; checking the remaining stroke and remaining load-bearing capacity of each hydraulic self-locking point; and checking the remaining adjustment range of the pipe supports. If any check result fails to meet the safety requirements, the control unit keeps the water injection control valve closed and prohibits the water injection phase.

[0112] After the safety inspection is completed, the control unit records the initial pressure and initial displacement of each hydraulic self-locking fulcrum, the initial elevation of each tank settlement monitoring position, the initial tilt of the tank, the initial relative displacement between the tank pipe opening and the monitoring position of the adjacent pipeline, and the initial stress of the heating network pipeline, as a comparison benchmark for this water injection process.

[0113] In this embodiment, during the water injection process, the control unit opens the water injection control valve step by step according to the set water level stages. When the water level reaches the target water level of the current water injection stage, the water injection control valve is closed and the current water level is maintained. Subsequently, the fulcrum pressure, fulcrum displacement, tank settlement, tank tilt, pipeline displacement, and pipeline stress are collected.

[0114] The control unit will not proceed to the next water injection stage until the bearing capacity and settlement response of the current water injection stage have stabilized. This avoids further increasing the water injection load before the foundation deformation of the previous stage is completed, which would cause the settlement response of different stages to overlap.

[0115] The control unit also determines the adjustment margin of each hydraulic self-locking fulcrum based on its current load-bearing capacity and remaining stroke. When the current load-bearing capacity of any hydraulic self-locking fulcrum approaches its upper limit, or when the fulcrum displacement approaches its stroke limit, water injection stops even if the tank settlement has not yet reached the settlement control limit, and the load is redistributed through adjacent hydraulic self-locking fulcrums. This process is a preventative measure to address insufficient adjustment capacity and prevent the hydraulic self-locking fulcrums from losing their adjustment margin during subsequent water injection phases.

[0116] The control unit identifies abnormalities in the detection data based on the detection range, the changes between adjacent time points, and the relationship between different detection parameters.

[0117] For example, when the outer ring hydraulic self-locking fulcrum The pressure reading changed abruptly, but the displacement of that fulcrum and the corresponding tank settlement monitoring location... If the elevation, pressure of adjacent hydraulic self-locking fulcrums, and tank tilt do not change in accordance with the pressure surge, the pressure reading is marked as abnormal. Before the pressure readings are verified, the control unit does not adjust the hydraulic self-locking fulcrums based on this pressure reading. Adjust the pressure by increasing or decreasing it.

[0118] When the settlement monitoring device shows a sudden change in the elevation of the tank area, but the fulcrum displacement, tank tilt, and adjacent settlement monitoring results in the same area do not change accordingly, the settlement monitoring result is marked as abnormal data. The control unit maintains the locked state of each hydraulic self-locking fulcrum, closes the water injection control valve, and re-acquires data.

[0119] Abnormal detection data includes detection values ​​exceeding the measurement range, abnormal jumps in detection values ​​between adjacent sampling times, detection values ​​remaining unchanged for extended periods, and contradictory detection results within the same area. If abnormal data occurs consecutively or fails to return to normal after re-collection, the control unit will issue a sensor fault alarm and will not execute automatic adjustments dependent on that detection data.

[0120] After the current water injection phase is completed and locked, if the hydraulic self-locking fulcrum... As the pressure gradually decreases, the control unit combines the mechanical lock status, fulcrum displacement, and tank settlement to determine the nature of the fault.

[0121] When the hydraulic pressure drops, but the mechanical lock remains locked, and the fulcrum displacement does not change, this corresponds to the tank settlement monitoring position. When the elevation remains stable, it is determined that there is a loss of pressure or leakage in the hydraulic branch, but the fulcrum is still held in position by the mechanical lock. At this time, the control unit closes the hydraulic self-locking fulcrum. The isolation valve of the independent hydraulic branch maintains the locked state of the remaining hydraulic self-locking fulcrums and suspends water injection. In this state, the entire load is not immediately transferred to the adjacent fulcrums; instead, the mechanical lock is first checked to ensure it can continue to hold.

[0122] When the hydraulic pressure drops, and simultaneously the fulcrum displacement retracts, the elevation of the corresponding tank area decreases, or the load-bearing capacity of adjacent fulcrums increases, the hydraulic self-locking fulcrum is identified. The load-bearing condition has changed. The control unit immediately closes the water injection control valve and isolates the hydraulic self-locking fulcrum. The load that needs to be transferred is determined as the fault load transfer amount.

[0123] When the mechanical lock cannot enter the locked position, or the displacement of the hydraulic self-locking fulcrum continues to change, the hydraulic self-locking fulcrum is identified as a faulty fulcrum that can no longer perform adjustment tasks, and no more pressurization, depressurization, or unlocking commands are sent to it.

[0124] For the outer ring hydraulic self-locking fulcrum In the event of a malfunction, the inner hydraulic self-locking pivot point in the same circumferential region should be selected first. and the adjacent outer ring hydraulic self-locking pivots on both sides and As a candidate support point.

[0125] The control unit determines the load margin and remaining stroke of each candidate load-bearing support. The load margin is the difference between the allowable load capacity of the candidate load-bearing support and the current load capacity. The remaining stroke is the distance between the current displacement of the candidate load-bearing support and the corresponding stroke limit position.

[0126] The fault load transfer amount is distributed according to the following formula:

[0127] In the formula, The load that needs to be transferred at the faulty fulcrum. To be allocated to the first The load of each candidate bearing support point For the first The allocation coefficients for each candidate bearing support point are such that the sum of all allocation coefficients is 1.

[0128] The allocation coefficient is determined based on the load margin, remaining stroke, distance from the faulty support point, and the zonal force relationship of the zoned load-bearing raft. After allocation, the load-bearing capacity of each candidate support point must not exceed its respective load limit, and the load-bearing capacity difference between adjacent hydraulic self-locking supports must not exceed the corresponding limit.

[0129] Load transfer employs a phased pressurization method. After each load is distributed to a candidate bearing support, the control unit maintains the current water level and re-collects data on support pressure, support displacement, tank settlement, and tank tilt. The next load transfer is executed only when the bearing and settlement responses are stable and no new local settlement occurs.

[0130] If the load-bearing margin or remaining stroke of the candidate bearing support is insufficient to receive the fault load, forced load transfer will not be executed. The water injection control valve will remain closed, and a fault shutdown alarm will be issued. Subsequent processing will proceed after the faulty bearing support is repaired or temporary bearing measures are added.

[0131] When the hydraulic self-locking fulcrum fails When the area is near the tank opening, the control unit, before transferring the load, determines the impact of pressurizing the candidate bearing support on the relative displacement of the tank opening and the pipeline stress based on the response relationship obtained from the pre-injection trial adjustment.

[0132] When expected to move towards the inner hydraulic self-locking fulcrum If the transfer of load from the adjacent outer ring hydraulic self-locking fulcrum increases the relative displacement of the tank opening or raises the pipeline stress, adjust the pipeline supports first. This allows the heating network pipeline to generate a compensating displacement in advance that is adapted to the expected direction of pipe displacement, and then the fulcrum load transfer is performed.

[0133] During load transfer, the pipeline displacement detection device and the pipeline stress detection device continuously monitor the pipe section adjacent to the tank inlet. When the pipeline stress change rate exceeds the stress change rate limit, or when the pipeline stress reaches the stress control limit, the fulcrum adjustment is immediately stopped, and the hydraulic self-locking fulcrum that has been adjusted is locked.

[0134] When pipe supports and hangers If jamming, unresponsive adjustment, or insufficient remaining adjustment amount occurs, the fulcrum adjustment that might increase pipeline displacement deviation will not continue. The control unit will maintain the current water level, close the water injection control valve, and issue a pipeline support / hanger fault alarm.

[0135] When the adjustment of the fulcrum causes the pipeline stress to change in an unfavorable direction, but has not yet reached the stress control limit, the fulcrum should be restored to the position that was most recently verified without increasing the risk of local stress on the raft slab, and other candidate load-bearing fulcrums and pipeline support compensation amounts should be re-determined.

[0136] Specifically, after the fault point isolation and load redistribution are completed, the control unit rechecks the following status: The faulty fulcrum has been isolated from the hydraulic source and has not continued to displace; The load-bearing capacity and remaining stroke of the remaining hydraulic self-locking fulcrums meet the requirements for subsequent water injection; The load-bearing capacity difference between adjacent hydraulic self-locking fulcrums meets the limiting requirements; The differential settlement and tilt of the tank meet the control requirements of the current water injection stage; The relative displacement of the tank nozzles and the pipeline stress meet the corresponding control requirements; Each monitoring parameter reaches a stable state during the continuous monitoring period.

[0137] When all the above conditions are met, the target bearing capacity for the next water injection stage is re-determined based on the remaining hydraulic self-locking support points. Faulty support points no longer participate in the target bearing capacity allocation; their original target bearing capacity is redistributed according to the bearing capacity margin of adjacent support points and the force relationship of the raft slab.

[0138] If the remaining hydraulic self-locking fulcrum still has sufficient load-bearing capacity and adjustment stroke, the water injection control valve can be opened to enter the next water injection stage; if the remaining fulcrum cannot meet the subsequent water injection requirements, the water injection will remain suspended and will not continue to inject water even if the current tank elevation temporarily meets the requirements.

[0139] When the remaining extension stroke of the hydraulic self-locking fulcrum to be adjusted is less than the required extension amount, the control unit will not use the hydraulic self-locking fulcrum as the main lifting fulcrum, but will select hydraulic self-locking fulcrums with remaining stroke in the same circumferential area and adjacent areas to jointly undertake the adjustment task.

[0140] When the remaining retraction stroke of the fulcrum to be adjusted is insufficient, the pressure relief and retraction will not continue. Instead, the problem will be addressed by increasing the bearing capacity of adjacent fulcrums, adjusting the support status of pipe supports and hangers, or reducing the load increment in the next water injection stage.

[0141] When the remaining stroke of multiple adjacent hydraulic self-locking pivots is insufficient, the water injection control valve is closed and an alarm for insufficient adjustment stroke is issued. This status indicates that the system is no longer capable of compensating for settlement through the hydraulic self-locking pivots, and it is necessary to check the foundation deformation, raft condition, or install external auxiliary supports.

[0142] If the tank's settlement rate does not decrease during continuous monitoring if the current water level remains unchanged, or if the same settlement deviation area continues to settle after multiple adjustments, then the foundation deformation in that area is not yet stable.

[0143] At this point, the control unit stops increasing the lifting amount of the hydraulic self-locking fulcrum in that area and keeps the water injection control valve closed. Continuing to lift the hydraulic self-locking fulcrum may cause local bending of the raft slab and load concentration in adjacent areas; therefore, repeated lifting is not used to counteract the still-unstable foundation settlement.

[0144] The control unit records the settlement amount, settlement rate, bearing capacity of the supports, and changes in the displacement of the supports in the area, and determines whether it is local foundation deformation or overall foundation settlement based on the settlement status of adjacent areas. When the settlement continues to develop and reaches the conditions for safe handling, all hydraulic self-locking supports are kept locked, and manual inspection is initiated.

[0145] When a power outage occurs, the water injection control valve closes, and each independent hydraulic branch stops receiving adjustment commands. The hydraulic lock seals the hydraulic cylinder circuit, the mechanical lock maintains the position of the hydraulic self-locking fulcrum, and the adjusting components of the pipe supports remain in their pre-power-out positions.

[0146] When a communication failure occurs between the control unit and the detection component, the control unit will not use the detection data from before the communication interruption to continue calculating the new fulcrum adjustment. The water injection control valve remains closed, and all hydraulic self-locking fulcrums and pipe supports remain in the state of the most recently calibrated and qualified condition.

[0147] When a communication failure occurs between the control unit and a single hydraulic self-locking pivot, the independent hydraulic branch connected to that hydraulic self-locking pivot is isolated, and the load transfer is determined according to the single pivot failure logic.

[0148] After power or communication is restored to the system, water injection should not resume immediately. Instead, all operating parameters should be re-collected, the status of hydraulic locks, mechanical locks, and isolation valves should be checked, and the current water injection phase should be re-verified. Only after the verification results meet the control requirements can the water injection control valve be reopened.

[0149] After the hot water storage tank reaches full water and completes the stability check, each hydraulic self-locking fulcrum enters a state where hydraulic locks and mechanical locks are used together to maintain stability, and the control unit switches to long-term monitoring mode.

[0150] During long-term monitoring, when the settlement in a certain monitoring area gradually increases, but the tank tilt, relative displacement of the pipe opening, and pipeline stress have not yet reached the compensation triggering conditions, the mechanical lock of the hydraulic self-locking fulcrum is not immediately released, but the settlement trend is monitored.

[0151] When the settlement deviation, tank tilt, relative displacement of the tank nozzle, or pipeline stress reaches the compensation trigger condition, and the corresponding changes persist during the continuous monitoring period, the control unit determines that long-term compensation needs to be performed.

[0152] Before implementing long-term compensation, the control unit confirms that the water level in the hot water storage tank remains stable, the heating network pipeline is not in a rapid heating or cooling phase, the hydraulic self-locking fulcrum to be adjusted and adjacent fulcrums have sufficient load-bearing capacity and remaining stroke, and the pipeline supports and hangers have sufficient compensation capacity.

[0153] After the above conditions are met, the hydraulic cylinder of the self-locking fulcrum to be adjusted is gradually built up to bear the load, so that the hydraulic cylinder takes over the fulcrum load from the mechanical lock; after the fulcrum pressure and fulcrum displacement are stable, the mechanical lock is released and a small pressure increase or decrease adjustment is performed. For the area adjacent to the tank pipe opening, the corresponding pipe supports are adjusted according to the pipe displacement and pipe stress.

[0154] After each long-term compensation cycle is completed, the hydraulic and mechanical locks are reactivated, and tank settlement, support bearing capacity, pipeline displacement, and pipeline stress are continuously monitored. The long-term compensation cycle is considered complete only when all of the above conditions meet the full-water operation control requirements and the rate of change reaches a stable level.

[0155] In this embodiment, the bearing capacity limit, remaining stroke limit, single adjustment amount, adjustment rate, stability threshold, displacement compensation trigger value, stress compensation trigger value, and continuous monitoring period are determined based on the structural calculation results of the hot water storage tank, the stress verification results of the zoned bearing raft, the foundation deformation characteristics, the performance parameters of the hydraulic self-locking fulcrum, the stress analysis results of the heating network pipeline, and the measurement accuracy of the detection components. Uniform values ​​that are detached from specific engineering conditions are not adopted.

[0156] In summary, this embodiment has at least the following technical effects: This invention determines the increment of water injection load at each water injection stage based on the water injection state of the hot water storage tank, and determines the target bearing capacity in combination with the arrangement position of the hydraulic self-locking fulcrum, so that the bearing state of the fulcrum is adjusted step by step with the water injection load, reducing the local stress concentration caused by one-time loading or passive bearing. This invention determines the area to be adjusted by measuring tank settlement, tilt, fulcrum bearing capacity, pipeline displacement, and pipeline stress. It also uses small-amplitude pressurization, depressurization, and differential grouping adjustment methods to correct the fulcrum bearing state, which helps to control differential settlement and tilt of the tank and avoids sudden changes in local stress on the raft plate caused by excessive adjustment. This invention incorporates the hydraulic self-locking fulcrum and the pipe support into the same adjustment process. The adjustment sequence and compensation amount of the two are determined according to the influence of the fulcrum adjustment on the displacement of the tank pipe opening and the stress of the pipe. This allows the tank leveling and the stress compensation of the heating network pipe to work together to reduce the relative displacement and additional stress between the tank pipe opening and the heating network pipe. This invention maintains the current water level after each adjustment and performs verification only after the tank settlement rate, fulcrum bearing capacity change rate, and pipeline stress change rate reach stable requirements, avoiding continuous adjustments based on instantaneous detection results. If the verification is successful, the next water injection stage begins; if the verification fails, the adjustment amount is re-determined, thus forming a closed loop of staged water injection, fulcrum adjustment, pipeline compensation, stability confirmation, and result verification. The zoned load-bearing raft adopts a structure that combines a central zone, a thickened outer ring zone, and radial reinforcing ribs. It is supported by inner and outer ring hydraulic self-locking supports, which allows the loads in the middle of the tank bottom, the tank wall, and the additional loads at the tank openings to be transferred along different zones. This helps to improve the raft's adaptability to uneven loads and local settlement. The multi-layer composite cushion layer, through the sequential combination of an impermeable isolation layer, a stress diffusion layer, an elastic pressure equalization layer, and a high-strength wear-resistant layer, diffuses the concentrated load transmitted by the hydraulic self-locking fulcrum to the foundation, buffers local deformation and fulcrum pressure changes, and provides a stable pressure-bearing support surface for the hydraulic self-locking fulcrum. Each hydraulic self-locking fulcrum adopts an independent hydraulic branch and is equipped with a hydraulic lock, a mechanical lock, and an isolation valve. In the event of pressure loss, power failure, communication abnormality, or single fulcrum failure, the system maintains the locked state of the remaining fulcrums, isolates the faulty fulcrum, and stops water injection. When the load margin and remaining stroke meet the requirements, the load of the faulty fulcrum is transferred to the adjacent fulcrum, thereby improving the safety maintenance capability under abnormal working conditions. After the hot water storage tank reaches full water, the system continues to monitor tank settlement, pipeline displacement, and pipeline stress. When long-term settlement or pipeline stress reaches the compensation condition, compensation is completed through controlled load replacement, unlocking, micro-adjustment, re-verification, and re-locking, so that the system can take into account the settlement control needs of both the water injection and commissioning phases and the long-term operation phase.

[0157] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
