Daily evaluation device and method for hydrostatic level system

Abstract

The invention discloses a daily evaluation device and method for a hydrostatic leveling system. The daily evaluation device comprises at least one group of hydrostatic leveling system formed by connecting a reference level and a working level in series, a plurality of sub-containers are also included; the sub-containers are communicated with a water supply system after being connected in parallelwith pipelines through sub-water inlet valves on the top surfaces of the sub-containers; the plurality of sub-containers are communicated with the hydrostatic leveling system through a water distributor after being connected in parallel with pipelines through sub-drain valves on the respective bottom surfaces of the sub-containers; and the hydrostatic level system is positioned below the sub-containers and has a fixed height difference value with the horizontal plane where the sub-containers are positioned. By means of the daily evaluation device of the hydrostatic leveling system, repeated quantitative irrigation of the system in the daily working period can be achieved so as to meet the requirements for benchmark measurement and evaluation of the hydrostatic leveling system. The evaluation device achieves equivalent water filling through the combination of the sub-containers connected with the water supply system after each test is finished and the same process, operation is convenient and rapid, repeated quantification is achieved, and the using function and effect of the evaluation device are stronger.

Description

technical field [0001] The invention relates to the technical field of static leveling, and more specifically relates to a daily detection and evaluation device and method for a multi-pipeline static leveling system. Background technique [0002] A hydrostatic level is a precision liquid level measurement system designed to measure the relative settlement of two or more measuring points. The energy level system is based on the use principle of the connector. The liquid level of the system is always kept horizontal under the condition of no pressure static force. The static characteristics of the liquid level of the public system. , this change in liquid level is sensed by the measuring instrument. [0003] Static leveling systems are widely used in large-scale projects and civil buildings such as nuclear power plants, dams, bridges, and tunnels. According to the requirements of the project, the leveling system is temporarily used, such as the bridge acceptance load test; i...

Problems solved by technology

As the test system prolongs over time, multiple factors such as liquid vaporization may cause changes in the liquid volume in the system. On the one hand, the law of water loss cannot be obtained, and the amount of water loss is unknown; on the other hand, the test system has requirements for liquid volume changes. Extremely strict, there is no relevant measuring instrument and realization method for quantitative or even micro-hydration

Therefore, such a high-precision static leveling test system cannot be used during non-test daily periods, and scientific data cannot be obtained for the evaluation of structural performance

[0007] For various static leveling systems in actual engineering that do have working points, the force sensor is abnormal and cannot be read, which leads to the degradation of the measurement system function. It is impossible to judge the structural settlement monitoring during the daily period. It has become a problem in the testing field. big problem

[0008] Previously, someone proposed to use high-precision measuring cylinders, measuring cups and other measuring instruments to fill water. Experiments showed that the operability is cumbersome. The volume of liquid measuring instruments in the existing market is limited, which is not suitable for large-scale use in engineering, and the cumulative error of repeated manual readings cannot meet the requirements.
