Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] The service environment of the hydraulic static level in the construction site includes temperature, humidity and vibration. Therefore, to test the influence of environmental factors on the measurement accuracy of the hydraulic static level, it is necessary to simulate the temperature, humidity and vibration of the service environment, and to test the temperature and humidity. And the impact of vibration on the measurement accuracy of the hydraulic static level.

[0026] The present invention provides a hydraulic static level instrument precision testing experimental platform such as figure 1 As shown, it includes a hydraulic static level connection module, a tempe...

Measuring point. The invention also discloses an experimental method of the precision testing experiment platform of the hydraulic static level, which can effectively test the influence of environmental factors on the testing accuracy of the hydraulic static level.

Description

technical field [0001] The invention relates to the technical field of simulation experiments, in particular to an experimental platform for testing the accuracy of a hydraulic static level. Background technique [0002] The static level is a high-precision liquid level measuring instrument, which is used to measure the relative settlement of each measuring point of the foundation and the building. The hydraulic static level uses a hydraulic sensitive unit to measure the pressure change value of the liquid reservoir at each measuring point relative to the The change of the reference point calculates the pressure change of each measuring point, and then solves the settlement change. The application site includes large buildings, such as hydropower plants, dams, high-rise buildings, nuclear power plants, water conservancy projects, railways, subways, high-speed rails and other measuring points for uneven settlement measurement. When applied to the construction site, the error...
