Abstract
Description
Technical Field
[0001] This invention relates to the field of pool construction technology, and in particular to a system and method for recycling water and mud at a multi-stage pool construction site. Background Technology
[0002] In the process of water and mud recycling at construction sites, multi-stage tanks are typically set up to settle, temporarily store, and reuse mud water, flushing water, or construction wastewater. This allows solids such as mud and sand to settle gradually, while the clearer water is reused in subsequent tanks or circulating water tanks for vehicle washing, site dust suppression, equipment cleaning, and other construction processes. This method reduces the discharge of construction wastewater, increases the on-site water resource reuse rate, and reduces the pressure on mud transportation and construction waste disposal.
[0003] In actual construction, multi-stage pools are not always operating at a stable full load. As slurry water continues to enter, stagnant materials gradually accumulate, sludge accumulates, or there may be partial blockages in each pool, requiring sludge removal, cleaning, or maintenance in some pools. Existing treatment methods typically focus on whether a single pool needs cleaning, or restoring the connectivity of the pool after cleaning, but they do not adequately consider the position of the pool in the original water flow direction and its impact on the continuity of adjacent pools.
[0004] Especially when a pool needs to temporarily withdraw from the original water flow due to sludge removal or sludge cleaning, water from the adjacent upstream pool may bypass the pool to be maintained and directly enter the adjacent downstream pool. If there is a large drop in elevation between the adjacent upstream and downstream pools, or if the remaining thickness of the connection layer in the adjacent downstream pool is insufficient to receive the incoming water, the upstream water can easily rush directly into the connection layer of the downstream pool, weakening the originally formed stable connection layer in the downstream pool, causing sludge and water disturbance to be transmitted to subsequent stages, and thus affecting the stability of subsequent recycled water.
[0005] Therefore, a system and method for recycling water and mud at construction sites based on multi-stage pools is proposed. Summary of the Invention
[0006] The purpose of this invention is to provide a system and method for recycling water and mud at construction sites based on multi-stage pools, in order to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides a method for recycling water and mud at a construction site based on a multi-stage pool, comprising the following specific steps: Step 1: When the mud and water are recycled through multiple pools at the construction site, obtain the maintenance occupancy of each pool, the drop between adjacent upstream pools and adjacent downstream pools, and the remaining thickness of the connection layer of adjacent downstream pools. Step 2: When the maintenance occupancy of any pool meets the maintenance triggering condition, the pool is identified as the pool to be maintained, and the adjacent upstream pool and adjacent downstream pool corresponding to the pool to be maintained are identified. Step 3: Before the pool to be maintained exits the original water flow connection, based on the cross-pool connection drop and the remaining thickness of the connection layer, determine whether the connection layer of the adjacent upstream pool will be weakened after the adjacent downstream pool crosses the pool to be maintained. Step 4: When the judgment result is that it will weaken the connection layer, restrict the adjacent upstream pool to directly connect to the adjacent downstream pool by crossing the pool to be maintained, and keep the pool to be maintained from participating in the current water flow connection. Step 5: After the sludge or slag is removed from the tank to be maintained, the maintenance occupancy of the tank to be maintained and the remaining thickness of the connecting layer of the adjacent downstream tank are obtained again. Step 6: When the re-acquired maintenance occupancy is lower than the post-maintenance connection limit and the remaining thickness of the connection layer meets the connection maintenance requirements, restore the tank to be maintained to the original water flow connection; otherwise, continue to restrict its participation in the original water flow connection.
[0008] Preferably, the determination of the maintenance occupancy includes: Obtain the height of the connecting channel of the pool to be judged in the original water flow direction, and the remaining space of the connecting channel after the stagnation in the pool occupies the height of the connecting channel; Based on the relationship between the remaining capacity of the connecting channel and the height of the connecting channel, the maintenance occupancy of the pool is determined; When the maintenance occupancy reaches a level where the remaining capacity of the connection channel is insufficient to maintain the original water flow continuity, the pool body is determined to meet the maintenance triggering condition. The maintenance occupancy is used to determine the pool to be maintained and to determine whether adjacent pools need to restrict direct connection after the pool to be maintained is removed from the original water flow.
[0009] Preferably, the determination of the cross-pool connection drop includes: Obtain the outflow reference height of the adjacent upstream pool in the original water flow continuation direction, and the continuation layer bearing height of the adjacent downstream pool for receiving upstream water. Based on the height difference between the outflow reference height and the receiving height of the connecting layer, the cross-pool connection drop between adjacent upstream pools and adjacent downstream pools is determined. When the drop between the two pools increases to the point that the water from the adjacent upstream pool directly flows into the connection layer of the adjacent downstream pool, it is determined that the drop between the two pools exceeds the allowable connection range. The cross-pool connection drop is used to determine whether the connection layer of the adjacent downstream pool will be weakened after the adjacent upstream pool crosses the pool to be maintained, based on the remaining thickness of the connection layer of the adjacent downstream pool.
[0010] Preferably, determining the remaining thickness of the splicing layer includes: Obtain the upper boundary height of the connecting layer in the adjacent downstream pool that is used to receive water from the upstream, and the lower limit height of the connecting layer affected by stagnant or disturbed water. The remaining thickness of the connecting layer of the adjacent downstream pool is determined based on the height difference between the upper boundary height and the lower limit height of the connecting layer. When the remaining thickness of the splicing layer is lower than the splicing maintenance requirement, it is determined that the splicing layer of the adjacent downstream pool is insufficient to receive the upstream water crossing the pool to be maintained. The remaining thickness of the connection layer is used, together with the drop across the pool, to determine whether the connection layer of the adjacent upstream pool will weaken the connection layer of the adjacent downstream pool after the adjacent upstream pool crosses the pool to be maintained.
[0011] Preferably, the determination of whether the adjacent upstream pool will weaken the connection layer of the adjacent downstream pool after crossing the pool to be maintained includes: The difference in drop across the pool is compared with the remaining thickness of the connection layer of the adjacent downstream pool to determine whether the water flowing into the adjacent upstream pool after crossing the pool to be maintained enters the receiving range corresponding to the remaining thickness of the connection layer. When the drop across the pool exceeds the bearing range corresponding to the remaining thickness of the connection layer, it is determined that the incoming water after the adjacent upstream pool crosses the pool to be maintained will weaken the connection layer of the adjacent downstream pool. When the drop across the pool does not exceed the bearing range corresponding to the remaining thickness of the connection layer, it is determined that the incoming water after the adjacent upstream pool crosses the pool to be maintained does not weaken the connection layer of the adjacent downstream pool. The determination result of weakening the connection layer of adjacent downstream pools is used to determine whether to restrict adjacent upstream pools from directly connecting to adjacent downstream pools across the pool to be maintained.
[0012] Preferably, the restriction that adjacent upstream pools cross the pool to be maintained and directly connect to adjacent downstream pools includes: When it is determined that the adjacent upstream pool will weaken the connection layer of the adjacent downstream pool after crossing the pool to be maintained, the water from the adjacent upstream pool will not directly enter the connection layer of the adjacent downstream pool, and the pool to be maintained will not participate in the current water flow connection. Before the remaining thickness of the connection layer meets the connection maintenance requirements again, adjacent upstream pools are not allowed to cross the pool to be maintained to form a direct connection; The restriction on direct connection is used to prevent the incoming water from weakening the connection layer of adjacent downstream pools due to the drop in water level across pools.
[0013] Preferably, the determination of restoring the water flow to the original state in the maintenance tank includes: After the sludge or slag is removed from the tank to be maintained, the maintenance occupancy of the tank to be maintained and the remaining thickness of the connecting layer of the adjacent downstream tank are obtained. When the maintenance occupancy is lower than the post-maintenance limit and the remaining thickness of the connection layer meets the connection maintenance requirements, it is determined that the tank to be maintained has the conditions to be restored to the original water flow connection. When the maintenance occupancy is not lower than the post-maintenance connection limit, or when the remaining thickness of the connection layer does not meet the connection maintenance requirements, the pool to be maintained will continue to be restricted from participating in the original water flow connection.
[0014] Preferably, the multi-stage pool body includes at least two pool body units connected in sequence, and the final pool body of the multi-stage pool body is connected to a circulating water tank. The circulating water tank is used to receive the recycled water after sedimentation treatment in the multi-stage pool body and supply water to the water points at the construction site.
[0015] Preferably, after completing the connection restriction or restoration of the pool to be maintained, a corresponding recycling record is generated. The recycling record includes the pool identifier, maintenance occupancy, cross-pool connection drop, remaining thickness of the connection layer, whether direct connection is restricted, and whether the original water flow connection is restored.
[0016] Secondly, the present invention provides a water and mud recycling system based on a multi-stage pool construction site, which is implemented as described above in a water and mud recycling method based on a multi-stage pool construction site, including: The data acquisition module is used to acquire the maintenance occupancy of each level of pool, the drop between inter-pool connections, and the remaining thickness of the connection layer; The module for determining the pool to be maintained is used to determine the pool to be maintained based on the maintenance occupancy, and to determine the corresponding adjacent upstream pool and adjacent downstream pool; The cross-pool connection judgment module is used to determine whether the connection layer of the adjacent upstream pool will be weakened after the adjacent upstream pool crosses the pool to be maintained, based on the cross-pool connection drop and the remaining thickness of the connection layer. The direct connection restriction module is used to restrict adjacent upstream pools from directly connecting to adjacent downstream pools across the pool to be maintained when the judgment result is that it will weaken the connection layer; The post-maintenance verification module is used to determine whether the tank to be maintained can be restored to the original water flow after the sludge or slag is removed from the tank to be maintained, based on the newly acquired maintenance occupancy and the remaining thickness of the connecting layer. The circulating water tank supply module is used to receive recycled water after multi-stage pool treatment and supply water to water points at the construction site; The record generation module is used to generate recycling records.
[0017] The technical effects and advantages of this invention are as follows: 1. This invention characterizes the degree to which stagnant matter in a pool occupies the original water flow connection channel by measuring the amount of stagnant matter. It then determines the pool to be maintained based on whether the stagnant matter meets the maintenance triggering conditions, directly linking pool maintenance judgment to the original water flow connection capability. This allows for timely identification of pools to be maintained when stagnant matter has already affected the connection channel, reducing instability in water flow connection caused by pools continuing to participate in the original water flow connection. It also provides a data basis for subsequent judgments on whether direct connection to adjacent pools needs to be restricted. 2. Before the pool to be maintained exits the original water flow connection, this invention, by combining the drop difference between the adjacent upstream pool and the adjacent downstream pool, and the remaining thickness of the connection layer of the adjacent downstream pool, determines whether the adjacent upstream pool will weaken the connection layer of the adjacent downstream pool after crossing the pool to be maintained. In this way, when the incoming water from the cross-pool may impact the downstream connection layer, it can restrict the direct connection between the adjacent upstream pool and the adjacent downstream pool, reducing the water flow disturbance caused by the drop difference between the cross-pools and preventing the weakening of the connection layer already formed in the adjacent downstream pool. 3. After the sludge or slag is removed from the tank to be maintained, this invention re-obtains the maintenance occupancy of the tank and the remaining thickness of the connecting layer of the adjacent downstream tank. Based on this, it determines whether to restore the original water flow. This ensures that the restoration process of the tank to be maintained is simultaneously constrained by the restoration status of its own connecting channel and the bearing capacity of the downstream connecting layer. This reduces the risk of premature restoration of the connection after maintenance, which could lead to further disturbance of the downstream connecting layer, thus improving the continuity and reuse stability of water and slurry recycling at the construction site.

[0018] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used together with the embodiments of the invention to explain the invention, but do not constitute a limitation thereof. In the drawings: Figure 1 This is a schematic diagram of the method of the present invention; Figure 2 This is a schematic diagram of the system of the present invention. Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] This invention provides, for example Figures 1-2 The method for recycling water and mud at a construction site based on a multi-stage pool system, as shown, includes the following specific steps: Step 1: When the mud and water are recycled through multiple pools at the construction site, obtain the maintenance occupancy of each pool, the drop between adjacent upstream pools and adjacent downstream pools, and the remaining thickness of the connection layer of adjacent downstream pools. Step 2: When the maintenance occupancy of any pool meets the maintenance triggering condition, the pool is identified as the pool to be maintained, and the adjacent upstream pool and adjacent downstream pool corresponding to the pool to be maintained are identified. Step 3: Before the pool to be maintained exits the original water flow connection, determine whether the connection layer of the adjacent upstream pool will weaken the connection layer of the adjacent downstream pool after the adjacent upstream pool crosses the pool to be maintained, based on the drop across the pool and the remaining thickness of the connection layer. Step 4: When the judgment result is that it will weaken the connection layer, restrict the adjacent upstream pool to directly connect to the adjacent downstream pool by crossing the pool to be maintained, and keep the pool to be maintained from participating in the current water flow connection. Step 5: After the sludge or slag is removed from the tank to be maintained, the maintenance occupancy of the tank to be maintained and the remaining thickness of the connecting layer of the adjacent downstream tank are obtained again. Step 6: When the re-acquired maintenance occupancy is lower than the post-maintenance connection limit and the remaining thickness of the connection layer meets the connection maintenance requirements, restore the tank to be maintained to the original water flow connection; otherwise, continue to restrict its participation in the original water flow connection.
[0021] Specifically, at a construction site, a series of interconnected pools are set up. The muddy water generated at the construction site enters these pools and undergoes progressive sedimentation treatment at each level. The treated water is then used for vehicle washing, dust suppression, and equipment cleaning, among other construction water applications. During continuous use, some pools accumulate sediment, which occupies available space in the original water flow direction. This sediment can negatively impact the flow stability between adjacent pools when that pool continues to participate in water flow.
[0022] When the mud slurry is recycled through multiple pools at the construction site, the maintenance occupancy of each pool, the drop between adjacent upstream and downstream pools, and the remaining thickness of the connection layer between adjacent downstream pools are first obtained. The maintenance occupancy indicates the degree to which stagnant matter within the pool occupies the space for the original water flow connection; the drop between pools indicates the potential impact of the drop when an adjacent upstream pool directly connects to an adjacent downstream pool after the pool to be maintained withdraws from the original water flow connection; and the remaining thickness of the connection layer indicates the thickness of the water layer in the adjacent downstream pool that can still stably receive water from the upstream.
[0023] When the maintenance occupancy of any pool meets the maintenance triggering condition, that pool is designated as a pool to be maintained, and the adjacent upstream and downstream pools corresponding to that pool are also identified. The maintenance triggering condition can be understood as follows: the stagnation within the pool has reduced the flow margin in the original flow direction to be sufficient to maintain the original flow continuity; if the pool continues to participate in the flow continuity, it may cause subsequent flow disturbances or instability.
[0024] Before the maintenance tank exits the original water flow, based on the drop difference between the adjacent upstream and downstream tanks and the remaining thickness of the connection layer of the adjacent downstream tank, it is determined whether the adjacent upstream tank will weaken the connection layer of the adjacent downstream tank after crossing the maintenance tank. Specifically, when the drop difference between the tanks is large and the remaining thickness of the connection layer of the adjacent downstream tank is insufficient to stably receive the water from the cross-tank, it is determined that the water from the adjacent upstream tank after crossing the maintenance tank will weaken the connection layer of the adjacent downstream tank.
[0025] When the assessment indicates that the connection layer would be weakened, the direct connection from the adjacent upstream pool to the adjacent downstream pool is restricted, and the pool to be maintained is kept out of the current flow connection. This process prevents the incoming water from the adjacent upstream pool from directly entering the connection layer of the adjacent downstream pool due to the drop in water level across the pool, thereby reducing disturbance to the existing connection layer in the adjacent downstream pool.
[0026] After the sludge removal or slag cleaning of the maintenance tank is completed, the maintenance occupancy of the maintenance tank and the remaining thickness of the connection layer of the adjacent downstream tank are re-acquired. When the re-acquired maintenance occupancy is lower than the post-maintenance connection limit and the remaining thickness of the connection layer of the adjacent downstream tank meets the connection maintenance requirements, the maintenance tank is restored to the original water flow connection; when the above conditions are not met, the maintenance tank is still restricted from participating in the original water flow connection.
[0027] The key to this method is not simply determining whether a particular tank needs sludge removal or cleaning, but rather, before the tank to be maintained withdraws from the original water flow connection, it uses the relationship between maintenance occupancy, the drop across tanks, and the remaining thickness of the connection layer to determine whether an adjacent upstream tank crossing the tank to be maintained will weaken the connection layer of the adjacent downstream tank. Furthermore, after the tank to be maintained completes sludge removal or cleaning, its original water flow connection is not immediately restored. Instead, it is re-verified based on the maintenance occupancy and the remaining thickness of the connection layer. Only when the maintenance occupancy decreases and the downstream connection layer still has the capacity to support it is the tank to be maintained reinstated in the original water flow connection. This reduces disturbance to the connection layers of adjacent tanks during the maintenance of a single tank, avoids instability caused by weakening the downstream connection layer or premature restoration after maintenance, and thus improves the continuity and stability of the water and slurry recycling process at the construction site.
[0028] Furthermore, the determination of maintenance occupancy includes: Obtain the height of the connecting channel of the pool to be judged in the original water flow direction, and the remaining height of the connecting channel after the stagnation in the pool occupies the connecting channel height; The maintenance occupancy of the pool is determined based on the relationship between the remaining capacity of the connecting channel and the height of the connecting channel. When the maintenance occupancy reaches a level where the remaining capacity of the connection channel is insufficient to maintain the original water flow, the pool is deemed to meet the maintenance triggering condition. The maintenance occupancy is used to identify the pool to be maintained and to determine whether direct connection to adjacent pools needs to be restricted after the pool to be maintained is removed from the original water flow.
[0029] Specifically, in the multi-stage pool recycling process, any pool is selected as the pool to be judged, and the height of the connecting channel in the original water flow direction is obtained. The connecting channel height can be understood as the range of heights in the pool that allow water to flow stably in the original water flow inflow and outflow directions, which is related to the effective water layer in the pool, the outflow position, and the original water flow direction.
[0030] Further, determine the remaining height of the connecting channel after the retained material in the pool occupies the height of the connecting channel. The retained material can be mud, sand, sludge, or other solid residues deposited at the bottom of the pool or near the connecting direction. The remaining height of the connecting channel indicates the height of the remaining channel in the pool that can still maintain the original water flow after the retained material occupies the channel.
[0031] The maintenance occupancy of the pool is determined based on the relationship between the remaining capacity of the connecting channel and its height. When the remaining capacity of the connecting channel is insufficient to maintain stable flow in the original water flow direction, it indicates that the stagnant material in the pool has significantly obstructed the original water flow. In this case, the pool is deemed to meet the maintenance triggering conditions and can be designated as a pool to be maintained.
[0032] In one implementation, the height of the connecting channel can be used as a benchmark, and the remaining space of the connecting channel after obstruction by debris is compared with this benchmark. The smaller the remaining space, the more significant the obstruction by debris in the original water flow connecting channel; if the remaining space is sufficient to maintain the original water flow, the pool is not directly designated as a pool requiring maintenance. This ensures that maintenance triggering is based on water flow continuity capability, rather than solely on the presence of debris within the pool.
[0033] By transforming maintenance assessment into an assessment of the degree of obstruction to the original water flow continuation channel by retained materials, the maintenance occupancy is determined through the correspondence between the continuation channel height and its remaining capacity. This directly links the identification of the pool to be maintained to whether that pool can still maintain the original water flow continuation. This avoids prematurely removing a pool from the continuation process when only a small amount of retained material is present, and also avoids allowing a pool to continue participating in the water flow continuation even when retained material has significantly compressed the continuation channel. Furthermore, since the maintenance occupancy is not used in isolation for cleaning assessment, but rather serves as preliminary data for subsequent cross-pool continuation drop assessment and protection of adjacent downstream pool continuation layers, it provides a more accurate basis for subsequent assessments of whether adjacent upstream pools need to restrict direct continuation, reducing continuation layer disturbances, cross-pool water inrushes, or maintenance recovery judgment errors caused by inaccurate identification of the pool to be maintained.
[0034] Furthermore, the determination of the cross-pool transition drop includes: Obtain the outflow reference height of the adjacent upstream pool in the original water flow continuation direction, and the continuation layer bearing height of the adjacent downstream pool for receiving upstream water. Based on the height difference between the outflow reference height and the receiving height of the connecting layer, determine the cross-pool connection drop between adjacent upstream pools and adjacent downstream pools; When the drop between the two pools increases to the point that the water from the adjacent upstream pool directly flows into the connection layer of the adjacent downstream pool, it is determined that the drop between the two pools exceeds the allowable connection range. The cross-pool connection drop is used to determine whether the connection layer of the adjacent downstream pool will be weakened after the adjacent upstream pool crosses the pool to be maintained, in conjunction with the remaining thickness of the connection layer of the adjacent downstream pool.
[0035] Furthermore, determining the remaining thickness of the connecting layer includes: Obtain the upper boundary height of the connecting layer in the adjacent downstream pool that is used to receive water from the upstream, and the lower limit height of the connecting layer affected by stagnant or disturbed water. The remaining thickness of the connecting layer of the adjacent downstream pool is determined based on the height difference between the upper boundary height and the lower limit height of the connecting layer. When the remaining thickness of the splicing layer is lower than the splicing maintenance requirement, it is determined that the splicing layer of the adjacent downstream pool is insufficient to hold the upstream water that crosses the pool to be maintained. The remaining thickness of the connection layer is used together with the drop across the pool to determine whether the connection layer of the adjacent upstream pool will weaken the connection layer of the adjacent downstream pool after the adjacent upstream pool crosses the pool to be maintained.
[0036] Once a pool is identified as requiring maintenance, it is necessary to determine whether an adjacent upstream pool can directly connect to the adjacent downstream pool, bypassing the pool requiring maintenance. To avoid relying solely on empirical judgment, the method determines the cross-pool connection drop and the remaining thickness of the connection layer, using these two factors as the data basis for subsequent judgments on whether the connection layer of the adjacent downstream pool will be weakened.
[0037] Specifically, first, the outflow reference height of the adjacent upstream pool in the original flow continuity direction is obtained. The outflow reference height can be the water layer height or outflow position height corresponding to the water flowing from the adjacent upstream pool to the next pool during normal flow continuity. Then, the receiving height of the connection layer in the adjacent downstream pool used to receive the upstream water is obtained. The receiving height of the connection layer can be understood as the water layer position in the adjacent downstream pool that can stably receive the upstream water.
[0038] Based on the height difference between the outflow reference height and the receiving height of the connection layer, the cross-pool connection drop between adjacent upstream and downstream pools is determined. This cross-pool connection drop reflects the potential impact on the connection layer of the adjacent downstream pool when the adjacent upstream pool bypasses the pool to be maintained and directly supplies water to the adjacent downstream pool after the pool to be maintained has withdrawn from the original water flow connection. The larger the cross-pool connection drop, the easier it is for the incoming water to directly enter the interior of the connection layer of the adjacent downstream pool.
[0039] Furthermore, the upper boundary height of the connecting layer in the adjacent downstream pool used to receive upstream water is obtained, as well as the lower limit height below the connecting layer affected by retained substances or disturbed water. The upper boundary height of the connecting layer can correspond to the upper water layer position in the adjacent downstream pool that stably receives upstream water; the lower limit height can correspond to the position below the connecting layer that is not suitable for directly receiving water due to retained substance accumulation, mud disturbance, or sediment.
[0040] The remaining thickness of the connecting layer in adjacent downstream pools is determined based on the height difference between the upper and lower limits of the connecting layer. This remaining thickness indicates the effective water layer thickness within the adjacent downstream pool that can still stably receive water from upstream. A small remaining thickness indicates insufficient stable water layer in the adjacent downstream pool to receive water from other pools; when the drop between pools is large and the remaining thickness of the connecting layer is insufficient, the incoming water from other pools is more likely to weaken the connecting layer of the adjacent downstream pool.
[0041] The method described above does not simply rely on whether adjacent pools are connected, whether there is a level difference, or whether water can flow out as the basis for direct connection. Instead, it correlates the outflow reference height of the adjacent upstream pool with the receiving height of the connection layer of the adjacent downstream pool, forming a cross-pool connection drop. Simultaneously, it correlates the upper boundary height of the connection layer in the adjacent downstream pool with the lower limit height affected by stagnant matter or disturbed water, forming the remaining thickness of the connection layer. Therefore, cross-pool connection judgment is no longer based solely on water level, but considers the relationship between the upstream water drop and the thickness of the downstream receiving water layer. This allows for a more accurate identification of whether cross-pool water will directly flow into the connection layer of the adjacent downstream pool. It avoids allowing direct connection from the upstream pool to the downstream pool simply because the adjacent pools are still connected after the maintenance pool has been removed, thus reducing the risk of the downstream connection layer being washed away, thinned, or disturbed, and providing more reliable data for deciding whether to restrict direct connection.
[0042] Furthermore, the determination of whether an adjacent upstream pool weakens the connection layer of an adjacent downstream pool after it crosses the pool to be maintained includes: The difference in drop across the pool is compared with the remaining thickness of the connection layer of the adjacent downstream pool to determine whether the incoming water after the adjacent upstream pool crosses the pool to be maintained enters the receiving range corresponding to the remaining thickness of the connection layer. When the drop across the pool exceeds the bearing range corresponding to the remaining thickness of the connection layer, it is determined that the incoming water after the adjacent upstream pool crosses the pool to be maintained will weaken the connection layer of the adjacent downstream pool. When the drop across the pool does not exceed the bearing range corresponding to the remaining thickness of the connection layer, it is determined that the incoming water after the adjacent upstream pool crosses the pool to be maintained does not weaken the connection layer of the adjacent downstream pool. The results of the assessment of weakening the connection layer of adjacent downstream pools are used to determine whether to restrict adjacent upstream pools from directly connecting to adjacent downstream pools across the pool to be maintained.
[0043] Furthermore, restricting the direct connection of adjacent upstream pools across the pool to be maintained to adjacent downstream pools includes: When it is determined that the adjacent upstream pool will weaken the connection layer of the adjacent downstream pool after crossing the pool to be maintained, the water from the adjacent upstream pool will not directly enter the connection layer of the adjacent downstream pool, and the pool to be maintained will not participate in the current water flow connection. Before the remaining thickness of the connection layer meets the connection maintenance requirements again, adjacent upstream pools are not allowed to cross the pool to be maintained to form a direct connection. Restricting direct connection is used to avoid the incoming water weakening the connection layer of adjacent downstream pools due to the drop in water level across pools.
[0044] Once the pool to be maintained is determined, it is not allowed for the adjacent upstream pool to directly cross over the pool to be maintained to connect to the adjacent downstream pool. Instead, the drop in height between the cross-pool connection and the remaining thickness of the connection layer of the adjacent downstream pool are first compared to determine whether the water coming from the cross-pool will weaken the connection layer of the adjacent downstream pool.
[0045] Specifically, the drop in elevation between adjacent upstream and downstream pools is correlated with the remaining thickness of the connection layer in the adjacent downstream pool. The catchment area corresponding to the remaining thickness of the connection layer can be understood as the range of water layers in the adjacent downstream pool that can stably catch the incoming water from the upstream pool without being easily dispersed. When the drop in elevation between the pools does not exceed this catchment area, it indicates that the incoming water from the adjacent upstream pool can be stably caught by the connection layer of the adjacent downstream pool without significantly weakening the connection layer.
[0046] When the drop in water level between adjacent pools exceeds the bearing capacity corresponding to the remaining thickness of the connecting layer, it indicates that the incoming water from the adjacent upstream pool, after crossing the pool to be maintained, can easily enter the connecting layer of the adjacent downstream pool directly, or cause the originally relatively stable water layer within the connecting layer to be impacted, thinned, or experience disturbance transmission. In this case, it is determined that the incoming water from the adjacent upstream pool, after crossing the pool to be maintained, will weaken the connecting layer of the adjacent downstream pool.
[0047] When the determination result indicates that the connection layer will be weakened, direct connection from an adjacent upstream pool to an adjacent downstream pool across the pool to be maintained should be restricted. Specifically, this may include: preventing the incoming water from the adjacent upstream pool from directly entering the connection layer of the adjacent downstream pool, and preventing the pool to be maintained from participating in the current water flow connection; and not allowing the adjacent upstream pool to cross the pool to be maintained to form a direct connection until the remaining thickness of the connection layer of the adjacent downstream pool meets the connection maintenance requirements again.
[0048] If the assessment concludes that the connection layer will not be weakened, then adjacent upstream pools can continue to participate in the water flow connection according to the recycling needs of the construction site, or continue to enter the subsequent connection assessment process. Thus, whether an adjacent upstream pool can directly connect to an adjacent downstream pool no longer depends on whether the two pools are connected, but rather on whether the drop across the pools will actually weaken the downstream connection layer.
[0049] The method described above transforms the decision on whether to allow adjacent upstream pools to directly connect across the pool to be maintained into a judgment based on the difference in elevation between the connection points and the remaining thickness of the connection layer, rather than simply connecting directly according to the original pool connection sequence or temporary needs at the construction site. Its innovative approach lies in the fact that the difference in elevation between the connection points reflects the potential impact of upstream water entering the downstream pool, while the remaining thickness of the connection layer reflects the downstream pool's ability to stably receive incoming water. Both factors jointly determine whether direct connection will weaken the downstream connection layer. This prevents upstream water from directly rushing into the downstream connection layer without proper assessment after the pool to be maintained is removed, reducing the risk of the downstream connection layer being dispersed, thinned, or affected by disturbed water. Furthermore, restricting direct connection does not simply interrupt water flow; rather, it protects the connection relationship between adjacent pools based on the weakening assessment result, ensuring that the multi-stage pools can maintain the stability of the recycling process as much as possible during localized maintenance.
[0050] Furthermore, the determination of whether the maintenance tank should be restored to its original water flow includes: After the sludge or slag is removed from the tank to be maintained, the maintenance occupancy of the tank to be maintained and the remaining thickness of the connecting layer of the adjacent downstream tank are obtained. When the maintenance occupancy is lower than the post-maintenance limit and the remaining thickness of the connection layer meets the requirements for maintaining the connection, it is determined that the tank to be maintained is ready to resume the original water flow. If the maintenance occupancy is not lower than the post-maintenance limit, or if the remaining thickness of the connection layer does not meet the connection maintenance requirements, the pool to be maintained will continue to be restricted from participating in the original water flow connection.
[0051] After sludge removal or slag cleaning is completed in the maintenance tank, the original water flow is not immediately restored. Instead, data related to the restoration of the flow is reacquired. Specifically, the maintenance occupancy of the maintenance tank is reacquired, and the remaining thickness of the connection layer of the adjacent downstream tank is also acquired.
[0052] The newly acquired maintenance occupancy level is used to determine whether the obstruction of the original water flow connection channel by the stagnant matter in the tank to be maintained has been reduced to a level that allows for the restoration of the connection. If the maintenance occupancy level is still high, it indicates that although the tank has undergone sludge removal or slag cleaning, the connection channel in the original water flow direction may still be obstructed by stagnant matter, and it is not advisable to directly restore the connection.
[0053] The remaining thickness of the connection layer between adjacent downstream pools is used to determine whether the downstream pool still has the capacity to receive the restored water flow. If the remaining thickness of the connection layer between adjacent downstream pools is insufficient, even if the maintenance occupancy of the pool to be maintained has been reduced, restoring the pool to be maintained to participate in the original water flow may still lead to the weakening or disturbance of the downstream connection layer.
[0054] Therefore, when the re-acquired maintenance occupancy is lower than the post-maintenance continuity limit, and the remaining thickness of the continuity layer in the adjacent downstream pool meets the continuity maintenance requirements, the pool to be maintained is deemed to have the conditions to resume the original water flow continuity, and is thus restored to the original water flow continuity. Conversely, when the maintenance occupancy is not lower than the post-maintenance continuity limit, or the remaining thickness of the continuity layer in the adjacent downstream pool does not meet the continuity maintenance requirements, the pool to be maintained is still restricted from participating in the original water flow continuity.
[0055] By basing post-maintenance recovery assessments on two data conditions—whether the maintenance occupancy has decreased and whether the downstream connection layer still has the capacity to receive water—this approach avoids premature connection of the tank to be maintained before its own connection channels have fully recovered, and also prevents further disturbance caused by the restoration of incoming water when the remaining thickness of the downstream connection layer is insufficient. Therefore, the restoration of the tank to be maintained is constrained by both the effectiveness of its own maintenance and the capacity of adjacent downstream tanks, reducing the likelihood of premature post-maintenance recovery, weakening of the downstream connection layer, and renewed instability in the water flow connection.
[0056] Furthermore, the multi-stage pool includes at least two pool units connected in sequence. The final pool of the multi-stage pool is connected to a circulating water tank, which is used to receive the recycled water after sedimentation treatment in the multi-stage pool and supply water to the water points at the construction site.
[0057] Furthermore, after completing the connection restriction or restoration of the pool to be maintained, a corresponding recycling record is generated. The recycling record includes the pool identification, maintenance occupancy, cross-pool connection drop, remaining thickness of the connection layer, whether direct connection is restricted, and whether the original water flow connection is restored.
[0058] The construction site is equipped with multi-stage pools, each consisting of at least two interconnected pool units. Muddy water, flushing water, or mud-containing construction wastewater generated at the construction site enters the multi-stage pools and undergoes sedimentation treatment in each pool unit, allowing silt, sand, sludge, and other retained materials to settle progressively. The treated reclaimed water then enters the final pool.
[0059] The final stage of the multi-stage water treatment system is connected to a circulating water tank. The circulating water tank receives the recycled water after treatment in the multi-stage water treatment system and transports it to water usage points on the construction site. These points may include vehicle washing stations, dust suppression stations, equipment cleaning stations, or other auxiliary water usage locations. This setup creates a water and slurry recycling path on the construction site, allowing the treated water to re-enter the construction water usage process.
[0060] During the operation of a multi-stage pool system, when a pool is identified as requiring maintenance and connection restrictions are lifted or connections are restored, a corresponding recycling record is generated. This recycling record may include information such as pool identification, maintenance occupancy, cross-pool connection drop, remaining connection layer thickness, whether direct connection is restricted, and whether the original water flow connection has been restored.
[0061] For example, once a pool is identified as a pool requiring maintenance due to its maintenance occupancy meeting the maintenance trigger conditions, the pool identifier, maintenance occupancy, and the corresponding adjacent upstream and downstream pools can be recorded in the recycling record. Furthermore, when determining whether an adjacent upstream pool crossing the pool requiring maintenance will weaken the connection layer of the adjacent downstream pool, the cross-pool connection drop, the remaining thickness of the connection layer, and the determination result regarding whether direct connection is restricted can be recorded. After the pool requiring maintenance completes sludge removal or sludge cleaning, the re-acquired maintenance occupancy, the remaining thickness of the connection layer, and the treatment result regarding whether the original water flow connection has been restored can be recorded.
[0062] By employing the above methods, multi-stage pools, circulating water tanks, and recycling records serve as on-site implementation support, enabling data such as maintenance occupancy, inter-pool connection drop, and remaining thickness of the connection layer to be mapped to specific pool units and treatment results. Recycling records reflect the process of a pool being designated as requiring maintenance, with direct connection restricted, until connection is restored after maintenance, facilitating subsequent monitoring of connection changes across different pools during recycling. The circulating water tanks, in conjunction with water usage points on the construction site, allow the recycled water treated by the multi-stage pools to be used for flushing, dust suppression, or cleaning operations on the construction site, thus supporting the recycling of water and mud on-site.
[0063] Each level of the tank is equipped with physical sensors for acquiring information such as liquid level, location of stagnant matter, or water disturbance. These physical sensors include one or more of the following: liquid level sensors, sludge level sensors, pressure-type water level sensors, or turbidity sensors. Liquid level sensors are used to determine the water level height or the upper boundary height of the connecting layer within the tank; sludge level sensors are used to determine the upper edge position of stagnant matter within the tank; and turbidity sensors are used to help determine the lower limit height affected by disturbed water.
[0064] When determining the maintenance occupancy, the sludge level sensor in the test tank acquires the position of the upper edge of the stagnant material, and the liquid level sensor acquires the height of the connecting channel in the original water flow direction. Based on the relationship between the position of the upper edge of the stagnant material and the height of the connecting channel, the occupancy margin of the connecting channel is determined, and the maintenance occupancy is determined by the occupancy relationship between the occupancy margin of the connecting channel and the height of the connecting channel.
[0065] For example, in a certain tank unit, if the height of the connecting channel obtained by the liquid level sensor is 0.80m, and the corresponding occupied height at the upper edge of the stagnant material obtained by the sludge level sensor is 0.55m, then the remaining space of the connecting channel is 0.25m. If the ratio of this remaining space of the connecting channel to the height of the connecting channel is lower than the preset connection maintenance ratio, then the maintenance occupancy of the tank is determined to meet the maintenance triggering condition, and the tank is identified as a tank to be maintained. The above values are only used to illustrate the process of determining the maintenance occupancy and do not limit the specific values of the connecting channel height, occupied height, or remaining space of the connecting channel.
[0066] When determining the drop height between adjacent pools, a first level sensor is installed at the outflow position of the adjacent upstream pool, and a second level sensor is installed at the receiving position of the adjacent downstream pool. The first level sensor obtains the outflow reference height of the adjacent upstream pool, and the second level sensor obtains the receiving height of the connecting layer of the adjacent downstream pool. The drop height between the two is determined based on the height difference between them.
[0067] For example, if the first liquid level sensor obtains an outflow reference height of 1.20m for the adjacent upstream pool and the second liquid level sensor obtains a connection layer bearing height of 0.85m for the adjacent downstream pool, then the cross-pool connection drop between the adjacent upstream pool and the adjacent downstream pool is 0.35m.
[0068] When determining the remaining thickness of the continuation layer, the liquid level sensor in the adjacent downstream tank obtains the upper boundary height of the continuation layer, while the sludge level sensor or turbidity sensor obtains the lower limit height affected by retained substances or disturbed water. The remaining thickness of the continuation layer in the adjacent downstream tank is determined based on the height difference between the upper boundary height and the lower limit height.
[0069] For example, if the upper boundary height of the connecting layer between adjacent downstream pools is 0.95m, and the lower limit height affected by stagnant matter or disturbed water is 0.70m, then the remaining thickness of the connecting layer is 0.25m. If the drop across the pool is 0.35m, and this drop exceeds the bearing capacity corresponding to the remaining thickness of the connecting layer, then it is determined that the adjacent upstream pool will weaken the connecting layer of the adjacent downstream pool after crossing the pool to be maintained, and thus restricts the direct connection between the adjacent upstream pool and the adjacent downstream pool.
[0070] After the sludge removal or slag cleaning of the maintenance tank is completed, the position of the upper edge of the retained material in the maintenance tank is re-acquired using a sludge level sensor, and the maintenance occupancy is re-determined. Simultaneously, the remaining thickness of the connection layer is re-determined using level sensors, sludge level sensors, or turbidity sensors in adjacent downstream tanks. For example, if the re-acquired connection channel margin increases to 0.55m after maintenance, and the remaining thickness of the connection layer in the adjacent downstream tank meets the connection maintenance requirements, it can be determined that the maintenance tank is ready to resume its original water flow connection. If the re-acquired data still does not meet the corresponding requirements, the maintenance tank's participation in the original water flow connection will continue to be restricted.
