Description

Technical Field

[0001] The present invention relates to the technical field of static leveling measurement, and more particularly to a daily detection and evaluation device and method for a multi-channel static leveling system. Background Art

[0002] A hydrostatic level is a precision liquid level measurement system designed to measure the relative settlement of two or more measuring points. Based on the principle of communicating vessels, the hydrostatic level maintains a horizontal surface in the absence of pressure. Changes in the settlement of each measuring point result in changes in the liquid level at each point within the system. These changes in liquid level are detected by measuring instruments.

[0003] Static leveling systems are widely used in large-scale projects and civil construction, including nuclear power plants, dams, bridges, and tunnels. Depending on the project requirements, leveling systems can be used temporarily, such as for bridge acceptance load testing, or permanently, such as for lifecycle monitoring of differential settlement of the common raft foundation of the nuclear island containment vessel in a nuclear power plant. They are typically fixed to the dam body, bridge piers, or their supporting frames, while permanent installations are often embedded in concrete.

[0004] Several basic structures of static level are as follows Figure 1 To the attached Figure 3 As shown, attached Figure 1 The structure diagram of the reference level is as follows, which consists of a water storage bucket, a float bucket, a contact rod, a force sensor, a water inlet conduit, an exhaust outlet, an observation tube and a measuring cable. Figure 2 It is a working level with a force sensor, consisting of a water storage bucket, a float bucket, a contact rod, a force sensor, a water inlet conduit, an exhaust outlet, and a measuring cable. Figure 3 It is a working level without a force sensor, consisting of a water storage tank, a water inlet pipe and an exhaust outlet. According to the different uses and test accuracy requirements, the designed static level system has a multi-point parallel test system with a common reference point, as shown in the attached Figure 4 There are also multiple independent test systems connected in series, as shown in the attached Figure 5 As shown in the figure, there is also a hybrid system of the above two types, as shown in the attached Figure 6 As shown in the attached Figure 5 The working level of the test system with two independent series connections is as shown in the attached Figure 2 With force sensor structure, there are also Figure 3 There are two types of structures without force sensors. For working levels embedded in concrete, if the force sensor fails and cannot be removed and replaced, a test system without force sensors can be constructed by connecting two independent working levels in series.

[0005] Obviously, among the above-mentioned static leveling test systems, for the test system without a force sensor on the working level, the test strictly requires that the liquid in the system is stable and the volume is constant. However, for long-term use, in order to obtain high-precision settlement and deformation measurements, it is difficult to keep the liquid in the test system constant for a long time, because normal gasification of the liquid is indispensable. Therefore, for this type of system, the design starting point is often mainly for the verification of structural deformation during short-term pressure tests. For long-term operation, the structure has no test load, and the settlement and deformation state of the structure cannot be measured. Of course, if the system can be replenished with water so that the volume of the liquid in the system remains unchanged, a good analysis and evaluation of long-term settlement and deformation can be achieved.

[0006] Existing technology lacks a device for accurately replenishing water within existing test system pipes or containers. Over time, multiple factors, such as liquid vaporization, can cause changes in the liquid volume within the system. This makes it impossible to determine the pattern of water loss and the amount of water lost unknown. Furthermore, the test system has extremely strict requirements for liquid volume changes, and there are no relevant measuring instruments or methods for quantitative or even trace water replenishment. Therefore, this type of high-precision static leveling test system cannot be used during routine testing, and scientific data cannot be obtained for evaluating structural performance.

[0007] For various static leveling systems in actual engineering, there are working points in the working levels, but the force sensors are abnormal and cannot read the readings, which leads to the degradation of the measurement system function. It is impossible to judge the structural settlement monitoring during daily use. This has become a major problem plaguing the testing field.

[0008] Previously, some people proposed to use high-precision measuring cylinders, measuring cups and other measuring instruments to fill water. Experiments have shown that the operation is cumbersome, the volume of liquid measuring instruments on the existing market is limited, and they are not suitable for large-scale use in engineering projects. In addition, the cumulative error of manual readings after repeated use cannot meet the requirements.

[0009] Therefore, how to develop a set of precise quantitative watering devices with combined volumes and establish a daily evaluation system for static leveling through the principle of static leveling is an urgent problem that needs to be solved by those skilled in the art. Summary of the Invention

[0010] In view of this, the present invention provides a daily evaluation device for a static leveling system, aiming to solve the above technical problems.

[0011] In order to achieve the above object, the present invention adopts the following technical solutions:

[0012] A daily evaluation device for a static leveling system comprises a static leveling system composed of at least one group formed by a reference level and a working level connected in series; further comprising a plurality of sub-containers; the volumes of the plurality of sub-containers are different; the plurality of sub-containers are connected to a water supply system via sub-inlet valves and pipelines on their respective top surfaces connected in parallel; the plurality of sub-containers are connected to the static leveling system via a water distributor via sub-drain valves and pipelines on their respective bottom surfaces connected in parallel; the static leveling system is located below the sub-containers and has a fixed height difference with the horizontal plane where the sub-containers are located.

[0013] Through the above technical solution, the present invention designs the graded volumes of the sub-containers according to the water filling volume determined by the liquid level in the normal working middle range of each static leveling system. The nominal water filling volume of each leveling system can be flexibly realized by combining multiple sub-containers, that is, the nominal water filling volume of a certain group of static leveling systems is equal to the sum of the volumes of one or several sub-containers, that is, the working water level of a certain group of static leveling systems can be achieved at the normal working middle range through the water filling volume of one or several sub-containers. On the premise of ensuring that the sub-containers are filled with water, the problem of accurate quantitative water filling can be achieved; at the same time, the height difference between the sub-container and the static leveling system is constant, so that the static leveling system can be repeatedly filled with constant water. The process is simple and easy to operate, low cost, can be manually operated, does not require other electric facilities to drive, and has high reliability.

[0014] Preferably, in the daily evaluation device of the static leveling system, a centrally controlled main water inlet valve is installed between the plurality of sub-containers and the water supply system, so as to facilitate the unified control of the water inlet of the pipeline water supply system.

[0015] Preferably, in the daily evaluation device of the static leveling system, a centrally controlled main drain valve is installed between the plurality of sub-containers and the water distributor, so as to facilitate the unified control of drainage of the sub-containers.

[0016] Preferably, in the daily evaluation device for a static leveling system, the elevation of the horizontal main pipe of the parallel pipe between the sub-drain valve and the main drain valve is not lower than the elevation of the exhaust outlet of the level instrument of the static leveling system; and the elevation of the vertical main pipe of the parallel pipe between the sub-drain valve and the main drain valve covers the elevation of the water storage tanks of the reference level and the working level. This ensures that after the nominal fixed water volume is poured into the static leveling system, the liquid level remains within the vertical pipe between the sub-drain valve and the main drain valve, without introducing excessive errors.

[0017] Preferably, in the daily evaluation device of the static leveling system, the top surface of the sub-container is further provided with an exhaust valve to exhaust air before water is passed through to prevent bubbles from forming inside and thus avoid static imbalance.

[0018] Preferably, in the daily evaluation device of the static leveling system, at least one sub-container is designed according to the following rule: Vji, where: i = 1 to 4, j is an integer;

[0019] When i=1, V j1 =1*10 j V; when i = 2, V j2 =2*10 j V; when i=3, V j3 =2*10 j V; when i=4, V j4 =5*10 j V; j is an integer, V is the unit volume;

[0020] The combination of multiple sub-containers can realize a single static leveling system V j1 The volume of ∑Vji can reach V j1 ;

[0021] Where: In V j1 In ∑Vji, j is the smallest integer; in ∑Vji, i=1~4, j is an integer.

[0022] For example, the volumes of the sub-containers are designed in the following order: 0.1V, 0.2V, 0.2V, 0.5V, 1V, 2V, 2V, 5V, 10V, 20V, 20V, 50V; where V is the unit volume. The volume combination of the sub-containers can flexibly meet the quantitative requirements of each hydrostatic leveling system. This device has a wide range of continuous nominal volume injections and provides a water volume subdivision accuracy of 1*10 j V (j is the minimum value). In actual projects, the specifications and quantity of sub-containers can be optimized according to the number and volume of the static leveling system to be filled. Minimizing the number of sub-containers can conveniently achieve accurate quantitative filling of the established multi-channel static leveling system. Proper sub-container grading can greatly improve work efficiency.

[0023] Preferably, in the daily evaluation device for a static leveling system, a master control valve for unified control is installed between the main pipe of the manifold and the main drain valve; and separate control valves for controlling each set of the reference and working levels connected in series are installed on the branch pipes of the manifold. This facilitates unified and separate control of the water inflow to each set of the reference and working levels connected in series.

[0024] Preferably, in the daily evaluation device of the static leveling system, the main pipe of the water distributor is arranged in an inclined horizontal direction, and an air release valve is provided at the higher end and a water release valve is provided at the lower end, so as to facilitate both air and water discharge.

[0025] The present invention also provides an evaluation method for a daily evaluation device of a static leveling system, which specifically comprises the following steps:

[0026] S1. Design the volume of the sub-containers. For the first time, fill each static level system with water that can reach the middle range of normal operation through the volume combination of the sub-containers. Perform the initial measurement of the reference level to obtain the initial state of the liquid level. Before filling with water, ensure that the sub-containers, water distributors, and the connecting pipes between them are full of liquid without mixed bubbles.

[0027] S2. If the working point where the working level is located sinks, and the system liquid volume remains unchanged, measure the reference level again to obtain the current state of the liquid level; calculate the sinking amount △H of the working point based on the data obtained before and after the reference level, and evaluate the performance of the test structure;

[0028] S3. When the situation in step S1 occurs and the system liquid volume in S2 has changed, or after the test is completed, the water in the static level system is discharged through the drain valve of the water distributor; then the same process is used to re-fill the static level system with the same amount of water as in step S1 through the volume combination of the sub-containers, and the test and analysis are continued.

[0029] Through the above technical solution, the present invention can realize the same amount of water after each test is completed by draining the water through the daily evaluation device of the static level system. The sub-container combination can realize convenient water filling through the water supply system, and realize repeated water filling with accurate equal volume, and the water filling process is smooth, without generating bubbles, and the water system can realize static measurement. Accurate equal volume is achieved by filling the sub-container with water, and the standard is unified; no bubbles are generated, and no opportunity for external air to be injected; and in actual engineering, the settlement deformation measurement of the static level, the liquid in the test system is filled in before the test, and the liquid needs to be emptied after the test. Good dry protection is also considered from the durability aspect of the test system. Therefore, the evaluation method of the present invention has stronger functions and effects.

[0030] Preferably, in the above-mentioned evaluation method of the daily evaluation device of the static leveling system, in S2 and S3, ΔH is calculated by the following formula:

[0031] △H=(A a +A b +A c ) / A a *△H b

[0032] in:

[0033] A a : The inner cross-sectional area of the water storage cylinder of the working level;

[0034] A b : cross-sectional area of the annulus between the water storage cylinder and the buoy of the reference level;

[0035] A c : The internal cross-sectional area of the vertical pipe where the main drain valve is located;

[0036] △H b : The liquid level change value of the reference level is directly measured by the force sensor of the reference level;

[0037] Positive values indicate an increase, negative values indicate a decrease.

[0038] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a daily evaluation device and method for a static leveling system, which has the following beneficial effects:

[0039] 1. The present invention designs the volumetric gradations of the sub-containers based on the water filling volume determined by the liquid level in the normal working mid-range of each hydrostatic leveling system. The nominal water filling volume of each leveling system can be flexibly achieved by combining multiple sub-containers. That is, the nominal water filling volume of a group of hydrostatic leveling systems is equal to the sum of the volumes of one or more sub-containers. In other words, the water filling volume of one or more sub-containers can be used to ensure that the working water level of a group of hydrostatic leveling systems is at the normal working mid-range. While ensuring that the sub-containers are filled with water, precise quantitative water filling can be achieved. At the same time, the height difference between the sub-containers and the hydrostatic leveling system is constant, thereby achieving repeated constant water filling of the hydrostatic leveling system. Repeated precise quantitative water filling can be achieved. The process is simple and easy to operate, low in cost, can be manually operated, and does not require other electric devices to drive it, and has high reliability.

[0040] 2. The present invention uses a daily evaluation device for a static leveling system to achieve the same amount of water as before after each test. The sub-container can be easily filled with water through the water supply system, achieving repeated water filling with precise equal volume. The filling process is smooth and does not generate bubbles. The water system can achieve static measurement. Precise equal volume is achieved by filling the sub-container with water, with a unified standard; no bubbles are generated, and no opportunity for external air to be injected. Moreover, in actual engineering, the liquid in the test system for the settlement deformation measurement of the static level is filled before the test and needs to be emptied after the test. Good dry protection is also considered from the durability aspect of the test system. Therefore, the evaluation method of the present invention has stronger functions and effects.

[0041] 3. The present invention can flexibly achieve the quantitative requirements of each static leveling system water filling through the combination of sub-container volumes, with a wide range of continuous nominal volume filling amounts, and the device provides a water filling volume subdivision accuracy of 1*10 jV (j is the minimum value). In actual projects, the specifications and quantity of sub-containers can be optimized according to the number and volume of pipes to be filled or the working level and reference level. Minimizing the number of sub-containers can conveniently realize the precise quantitative filling of the established multi-channel containers. Proper sub-container grading can greatly improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0083] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0084] See attached Figure 7 An embodiment of the present invention discloses a daily evaluation device for a static leveling system, comprising a static leveling system 100 including at least one group formed by a reference level 101 and a working level 102 connected in series; further comprising a plurality of sub-containers 103; the volumes of the plurality of sub-containers 103 are different; the plurality of sub-containers 103 are connected to a water supply system 104 in parallel via sub-inlet valves 106 on their respective top surfaces and pipelines; the plurality of sub-containers 103 are connected to the static leveling system 100 via a water distributor 105 in parallel via sub-drain valves 107 on their respective bottom surfaces and pipelines; the static leveling system 100 is located below the sub-containers 103 and has a fixed height difference with the horizontal plane where the sub-containers 103 are located.

[0085] In order to further optimize the above technical solution, a centrally controlled main water inlet valve 108 is installed between the multiple sub-containers 103 and the water supply system 104 .

[0086] In order to further optimize the above technical solution, a centrally controlled main drain valve 109 is installed between the multiple sub-containers 103 and the water distributor 105 .

[0087] In order to further optimize the above technical solution, the elevation of the horizontal main pipe of the parallel pipes between the sub-drain valve 107 and the main drain valve 109 is not lower than the elevation of the exhaust outlet of the level of the static level system 100; the elevation of the vertical main pipe of the parallel pipes between the sub-drain valve 107 and the main drain valve 109 covers the elevation of the water storage tanks of the reference level 101 and the working level 102.

[0088] In order to further optimize the above technical solution, the top surface of the sub-container 103 is further provided with an exhaust valve 110 .

[0089] In order to further optimize the above technical solution, at least one sub-container 103 is designed according to the following rule: Vji, where: i = 1 to 4, j is an integer;

[0090] When i=1, V j1 =1*10 j V; when i = 2, V j2 =2*10 j V; when i=3, V j3 =2*10 j V; when i=4, V j4 =5*10j V; j is an integer, V is the unit volume;

[0091] The combination of multiple sub-containers 103 can realize a single static leveling system 100V j1 The volume of ∑Vji can reach V j1 ;

[0092] Where: In V j1 In ∑Vji, j is the smallest integer; in ∑Vji, i=1~4, j is an integer.

[0093] In order to further optimize the above technical solution, a main control valve 1050 for unified control is installed between the main pipeline of the water distributor 105 and the main drain valve 109; a sub-control valve 1051 for controlling each set of reference level 101 and working level 102 connected in series is installed on the branch pipeline of the water distributor 105.

[0094] In order to further optimize the above technical solution, the main pipeline of the water distributor 105 is arranged tilted in the horizontal direction, and the higher end is provided with an air release valve 1052, and the lower end is provided with a water release valve 1053.

[0095] See attached Figure 8 and attached Figure 9 The evaluation method of the daily evaluation device of the static leveling system provided by the present invention specifically includes the following steps:

[0096] S1. Design the volume of the sub-container 103. For the first time, fill each set of the static level system 100 with water that can reach the middle range of normal operation through the volume combination of the sub-container 103. Perform the initial measurement of the reference level to obtain the initial state of the liquid level. Before filling with water, ensure that the sub-container 103, the water distributor 105 and the connecting pipes therebetween are full of liquid without mixing in bubbles.

[0097] S2. If the working point where the working level 102 is located sinks, and the system liquid volume remains unchanged, measure the reference level again to obtain the current state of the liquid level; calculate the sinking amount ΔH of the working point using the data obtained before and after the reference level 101, and perform a performance evaluation on the test structure;

[0098] S3. When the situation in step S1 occurs and the system liquid volume in S2 has changed, or after the test is completed, the water in the static level system 100 is drained through the drain valve 1053 of the water distributor 105; then, using the same process, the same amount of water as in step S1 is re-filled into the static level system 100 through the volume combination of the sub-container 103, and the test and analysis are continued.

[0099] In S2 and S3, △H is calculated using the following formula:

[0100] △H=(A a +A b +A c ) / A a *△H b

[0101] in:

[0102] A a : The inner cross-sectional area of the water storage cylinder of the working level 102;

[0103] A b : cross-sectional area of the annulus between the water storage cylinder and the buoy of the reference level 101;

[0104] A c : The inner cross-sectional area of the vertical pipe where the main drain valve 109 is located;

[0105] △H b : The liquid level change value of the reference level 101 is directly measured by the force sensor of the reference level 101;

[0106] Positive values indicate an increase, negative values indicate a decrease.

[0107] The workflow of the present invention is:

[0108] (1) Based on the water volume determined by the normal working intermediate range liquid level of each branch static level system 100, the sub-container volume levels of the water filling device are designed, the nominal specifications and quantity of the sub-containers are determined, and finally an effective water filling device is designed. For example, if the volume of the static level system 100 to be filled is 8.3V, it can correspond to 0.1V+0.2V+1V+2V+5V (=8.3V), a total of 5 sub-containers 103 of water volume. That is, the static level system 100 can be filled with water through these 5 sub-containers 103.

[0109] (2) Install the water filling device on site and connect it to the hydrostatic level system 100 through the water distributor 105. It is important to install the sub-container at an elevation so that the liquid level after quantitative filling is within the normal working range of the hydrostatic level and is located between the vertical pipes between the sub-drain valve 107 and the main drain valve 109.

[0110] (3) Fill the sub-container with water and at the same time empty the air in the water pipe and the water distributor.

[0111] (4) Fill the corresponding static leveling system 100 with water according to the sub-container 103 corresponding to the selected nominal capacity.

[0112] (5) Carry out data measurement and comparative analysis with previous data, calculate the settlement changes of the working point, and evaluate the safety of the structure.

[0113] (6) Fill the static leveling system 100 of other branches with water, measure, calculate and analyze them in turn.

[0114] The device and method of the present invention effectively address the shortcomings of certain types of static leveling systems in practical engineering projects. They can be used for routine structural performance assessments and as a backup solution for static leveling settlement measurements during pressure testing. Their advantages are groundbreaking, comprehensively addressing the effectiveness of static leveling systems under various complex working conditions and under long-term use, remedying the shortcomings of existing systems or expanding their functionality.

[0115] This device, once installed, enables repeated, precise, and quantitative watering. It features a simple, easy-to-use process, low cost, and manual operation, requiring no electrical drive, resulting in high reliability. This invention expands the scope of use for static leveling systems, filling a gap in this field both domestically and internationally. In particular, the working level eliminates the need for a force sensor, resulting in a hollow tank design that significantly reduces investment costs and offers significant economic benefits.
