Portable water tube tiltmeter with double-measuring bar

Abstract

The invention discloses a portable water tube tiltmeter with double-measuring bar. The tiltmeter consists of two measuring bars, a transparent water tube, a dial gauge measuring and reading device anda plurality of stainless steel measuring seats; each measuring bar comprises a transparent measuring cylinder, a valve, a support bar and a stainless steel measuring head, the support bar is connected with the stainless steel measuring head and the transparent cylinder, and the valve is arranged on the transparent cylinder; a plurality of stainless steel measuring seats are buried at the parts ofdifferent measuring points respectively, the two measuring bars are located at different measuring points respectively, the stainless steel measuring heads of the two measuring bars are inserted intothe stainless steel measuring seats of different measuring points respectively, the water tube is communicated with the transparent cylinders of the two measuring bars by the valve, the transparent cylinders are filled with water, and the dial gauge measuring and reading device is inserted into the transparent cylinders to measure relative sedimentation values among the measuring points. The tiltmeter has the obvious advantages of higher precision, convenient carrying, no rust corrosion and aging problems, easy measuring point protection and instrument maintenance, lower cost and the like.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering observation, in particular to a portable water pipe inclinometer with double measuring poles. Background technique [0002] Both surface engineering and underground engineering may lead to vertical settlement deformation of the surface. When the amount of settlement deformation is large or the settlement difference of different parts (ie uneven settlement) is large, the construction process, long-term stability and operation effect of the project will often be adversely affected, and even catastrophic accidents will be caused. For example: [0003] ●Underground excavation projects (including underground mining, subway projects, etc.) sometimes cause subsidence funnels or subsidence zones on the surface, and when the uneven settlement is large, it will lead to surface cracking, surface subsidence, and cracking, tilting or collapse of buildings ; [0004] ●For surface excavation ...

AI Technical Summary

Problems solved by technology

[0029] The purpose of the present invention is to solve the problems of low precision, inconvenient portability, easy corrosion or aging, difficult instrument protection and maintenance, and high cost in the existing surface subsidence monitoring technology, and proposes a high-precision, easy-to-carry monitoring technology. , no rust and aging problems, easy to protect the measuring point and maintain the instrument, and a low-cost double-rod portable water pipe inclinometer, so as to improve the efficiency of surface subsidence monitoring
