Automatic lifting monitoring device equipped with invar level staff and used for monitoring ground surface settlement as well as method

Abstract

The invention discloses an automatic lifting monitoring device equipped with an invar level staff and used for monitoring ground surface settlement as well as a method. The device comprises a ZigBee remote control, a single chip microcomputer control box, a measuring hole protection device, an automatic lifting device and an improved barcode invar level staff. The method comprises the following steps: 1, an instruction is sent to the single chip microcomputer control box through the ZigBee remote control within a certain distance to control the measuring hole protection device and the automatic lifting device; 2, the single chip microcomputer control box sends an instruction, and the measuring hole protection device is opened; 3, the single chip microcomputer control box sends an instruction, the invar level staff automatic lifting device is started, and the invar level staff is lifted; 4, the invar level staff is dropped and retracted automatically after measurement, and the single chip microcomputer control box and the invar level staff automatic lifting device are retracted in the measuring hole protection device at ordinary times and are standby with quite low power. The automatic lifting monitoring device realizes remote control of automatic erection of the invar level staff through the portable ZigBee remote control, is simple and convenient, can be used for monitoring ground surface settlement during tunnel construction and greatly saves cost for manual erection of the invar level staff.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of monitoring and measurement, in particular to an indium steel ruler automatic lifting monitoring device and method for monitoring ground subsidence. [0003] 【Background technique】 [0004] In the process of tunnel construction, the new Austrian method NATM is now the mainstream construction method. Its principle is: when constructing a tunnel, make full use of the self-supporting capacity of the surrounding rock and the space constraints of the excavation surface, and use anchor rods and shotcrete as the main Support means, timely reinforce the surrounding rock, restrain the relaxation and deformation of the surrounding rock, and guide the design and construction of the underground project through the monitoring and measurement of the surrounding rock and support structure. Therefore, we can think that tunnel construction monitoring and measurement is the eye of NAMO construction and the main content of NAM...

Problems solved by technology

Different from other tunnels, the monitoring and measurement of surface settlement of subway tunnel construction has its own characteristics: the subway tunnel has a long mileage and many bid sections, especially for the shallow buried underground excavation method in the city, there are many monitoring and measurement points for a single bid section, and the amount of monitoring The measurement workload is huge, and the monitoring and measurement work is a relatively simple and highly repetitive work. It takes a lot of repetitive manpower to erect the indium steel ruler for the reading of the electronic level, and the consumption of manpower and material resources is extremely huge.

[0006] At the same time, in recent years, ZigBee wireless control technology, single-chip microcomputer technology, mechanical drive technology, damping vibration reduction technology, etc. have achieved relatively rapid development, and have achieved gratifying results in their respective fields, but the application of the above technologies in the field of monitoring and measurement It is not high and the scope is not wide. There are very few examples of technologies in the above-mentioned fields being integrated and used together to serve the field of monitoring and measurement.
