High-precision measuring device for engineering structure elevation and settlement deformation

Abstract

The invention discloses a high-precision measuring device for engineering structure elevation and settlement deformation. The device comprises a reference position balancing mechanism, measuring pointposition measuring mechanisms and communicating conduits. The reference position balancing mechanism comprises a first liquid storage tank, a first liquid inlet, an overflow port and a first liquid outlet are formed in the first liquid storage tank, and a first valve is arranged at the first liquid outlet. The number of the measuring point position measuring mechanisms and the number of the communicating conduits are both N. Each measuring point position measuring mechanism comprises a second liquid storage tank and a measuring pipe group, a second liquid inlet, a second liquid outlet A and asecond liquid outlet B are formed in the second liquid storage tank, a second valve A is arranged on the second liquid outlet A, a second valve B is arranged on the second liquid outlet B, the measuring pipe group comprises a flow guide pipe and a plurality of measuring pipes, one end of the flow guide pipe is communicated with the second liquid outlet A, the lower ends of the measuring pipes aresealed, the upper ends of the measuring pipes are open, scales are arranged on the measuring pipes, and the upper ends of the measuring pipes are communicated with the flow guide pipe. The device issimple in structure, low in manufacturing cost and convenient to mount and dismount, and can realize real-time monitoring of multiple observation points at the same time.

Description

technical field [0001] The invention relates to the technical field of engineering surveying, in particular to a high-precision measuring device for engineering structure elevation and settlement deformation. Background technique [0002] With the continuous advancement of social science and technology, architectural design and construction technology is also developing vigorously, and the height of building buildings is getting higher and higher, and the number is increasing. Therefore, settlement observation is very important for the safety and stability of buildings during construction and after completion. Sex plays a very important role in avoiding serious financial losses in the future. Specifically, building settlement observation is a necessary means of safety monitoring in the process of construction and operation management. It is a monitoring work with high technical requirements and time-consuming. It can reduce the construction cost, obtain reliable observation...

Problems solved by technology

At present, precision levels and copper leveling rods are widely used for subsidence point measurement observations. When subsidence observations at multiple observation points are involved, the surveyors need to frequently change the observation positions. Not only is the information acquisition process complicated, but the labor cost is high and the accuracy is low. , and the observation data is single, limited to the measurement at a certain time point, and the real-time monitoring of settlement cannot be realized
