Abstract

The invention discloses a high-precision measuring device for elevation and settlement deformation of an engineering structure, which includes a reference position balance mechanism, a measuring point measurement mechanism and a connecting conduit. The reference position balance mechanism includes a first liquid storage tank on which There are a first liquid inlet, an overflow port, and a first liquid outlet. The first liquid outlet is provided with a first valve. There are N measuring point measuring mechanisms and connecting conduits. The measuring point measuring mechanisms include the first Two liquid storage tanks and measuring tube sets, the second liquid storage tank is provided with a second liquid inlet, a second liquid outlet A and a second liquid outlet B, and the second liquid outlet A is provided with a second valve A , the second liquid outlet B is provided with a second valve B, the measuring tube group includes a diversion tube and a plurality of measuring tubes, one end of the diversion tube communicates with the second liquid outlet A, the lower end of the measuring tube is sealed, and the measuring tube The upper end of each measuring tube is open, the measuring tube is provided with a scale, and the upper end of each measuring tube is connected with the draft tube. The device has simple structure, low manufacturing cost, convenient installation and disassembly, 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
