Foundation settlement monitoring system based on laser measurement

Abstract

The invention discloses a foundation settlement monitoring system based on laser measurement, which mainly solves the problems of inconvenience, inaccurate result and poor real-time performance of theconventional foundation continuous settlement detection. The foundation settlement monitoring system mainly consists of controllers, lasers, two-dimensional photoelectric position sensitive devices,photoelectric displacement measuring modules, foundation settlement offset calculating modules, wireless communication modules and alarms. The foundation settlement monitoring system is characterizedin that: two or more monitoring points are arranged in areas with different geological conditions in space, each monitoring point is provided with a set of laser transmitting and receiving equipment,and the controller is used for measuring laser spot displacement parameters between the monitoring points and sending the laser spot displacement parameters to the controllers on other monitoring points through the wireless communication module; each monitoring point is provided with a laser emitter and a laser spot displacement detection circuit, and the monitoring points work intermittently, sothat the purpose of saving power consumption is achieved; and when a settlement value exceeds a preset alarm value, the alarm is started to warn, so as to remind related personnel of paying attentionto safety.

Description

technical field [0001] The present invention relates to a building detection method, in particular to a foundation settlement monitoring method. [0002] technical background [0003] With the rapid construction of water conservancy and hydropower projects, bridge construction, and housing construction in China, a number of large man-made structures such as high dams and reservoirs, super high buildings, and bridges have been built one after another. Affected by terrain, geology, hydraulic structure and other factors, the foundation of large-scale man-made buildings will have different degrees of settlement, which will have a great impact on the safety of the building itself. Usually, the safety monitoring of these buildings is mainly carried out by manual regular monitoring. The commonly used monitoring methods mainly include vertical lines, tension lines, surface deformation monitoring points, etc. The detection methods are leveling, triangular elevation measurement, etc. ...

AI Technical Summary

Problems solved by technology

Due to the limited monitoring scope and the constraints of traffic and hydrogeological conditions, the implementation of large-scale building settlement monitoring is difficult, and the monitoring is not timely, resulting in an incomplete safety assessment of large-scale man-made buildings.

[0004] The invention discloses a foundation settlement monitoring system based on laser measurement. The laser is transmitted in a straight line, and the displacement detection of the laser light spot is carried out in a non-contact manner, which mainly solves the inconvenient and inaccurate detection of the continuous settlement of the existing foundation. , The real-time problem is not strong
