An indium steel ruler automatic lifting monitoring device and method for monitoring ground subsidence

Abstract

The invention discloses an indium steel ruler automatic lifting monitoring device and method for monitoring ground subsidence. The device comprises: a ZigBee remote controller, a single-chip microcomputer control box, a hole measuring protection device, an automatic lifting device, and an improved indium steel bar code ruler. The method includes: 1. Sending instructions to the single-chip microcomputer control box within a certain distance through the ZigBee remote control to control the hole measuring protection device and the automatic lifting device; 2. The single-chip microcomputer control box sends instructions, and the hole measuring protection device opens; Indium steel ruler automatic lifting device, the indium steel ruler rises; 4. The indium steel ruler automatically falls and shrinks when the measurement is completed. Usually, the single-chip microcomputer control box and the indium steel ruler lifting device shrink in the measuring hole protection device, and stand by with very low power. This device realizes the automatic erection of the indium steel ruler by remote control through the portable ZigBee remote controller. The device is simple and convenient, and can be used for monitoring the surface settlement during tunnel construction, which greatly saves the cost of manually erecting the indium steel ruler.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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 NAMO field measure...

AI Technical Summary

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.

[0004] 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.
