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...

Abstract

The invention discloses a hydraulic hydrostatic leveling instrument precision test experiment platform comprising a hydraulic hydrostatic leveling instrument connection module, a temperature and humidity test module and a vibration test module; the hydraulic hydrostatic leveling instrument connection module comprises m hydrostatic leveling instruments, a liquid storage tank, an air pipe and a liquid pipe, and m is greater than or equal to 2; the temperature and humidity test module comprises a humidifying device used for simulating the environment humidity, a heating device used for simulatingthe environment humidity and a hygrothermograph used for monitoring the environment temperature and humidity. The vibration test module comprises a force hammer used for simulating a vibration working condition and an LMS test system used for monitoring the magnitude of vibration excitation. The hygrothermograph is connected with each temperature and humidity measuring point through signals, andthe LMS test system is connected with the force hammer and each vibration excitation measuring point through signals. The invention also discloses an experimental method of the hydraulic hydrostatic leveling instrument precision test experimental platform, and the influence of environmental factors on the test precision of the hydraulic hydrostatic leveling instrument can be effectively tested.

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...
