Automatic monitoring system and method for expressway post-construction settlement

Abstract

The invention discloses an automatic monitoring system and method for expressway post-construction settlement. The system comprises a datum column arranged on a datum point, and settlement columns arranged on a roadbed slope foot, a road shoulder and a roadbed center line correspondingly, wherein scale lines are marked on the settlement columns. Measurement boxes are arranged in the datum column and the settlement columns arranged on the roadbed slope foot and the road shoulder. Each measurement box comprises a high-precision laser locating lamp, a wireless transmission camera, a power sourcetimer and a high-energy storage battery. The laser locating lamps in the measurement boxes shine on the corresponding settlement columns marked with the scales, and meanwhile photograph the light spotcorresponding scales to be transmitted to a could server, the server calculates relative settlement of all measurement points and accumulates the settlement to obtain the settlement amount of the road surface relative to the set base point. The automatic monitoring system for post-construction settlement is easy to install and operate, the cost needed by the equipment is low, maintaining is convenient, batteries in the measurement boxes only need to be replaced regularly, the number of externally-connected circuits is reduced, the service life is prolonged, the stability is high, and real-time monitoring can be carried out for a long term conveniently.

Description

technical field [0001] The invention relates to an automatic monitoring system and method for expressway post-construction settlement, belonging to the technical field of highway settlement monitoring. Background technique [0002] With the development of modern society and economy, the construction of highways is increasing, and highways have very high requirements for foundations. At present, the foundation soil in my country's coastal areas has the characteristics of high water content, high compressibility and low strength. Therefore, the construction of highways in my country's coastal areas Subsidence and differential settlement diseases of roadbed are common in expressways. Post-construction settlement, especially uneven settlement, will inevitably cause unevenness of the road surface, resulting in many diseases on the road surface, mainly manifested as road arch deformation, structural layer cracking, floor voiding, pavement dislocation, muddying, potholes, cracks, an...

AI Technical Summary

Problems solved by technology

Post-construction settlement, especially uneven settlement, will inevitably cause unevenness of the road surface, resulting in many diseases on the road surface, mainly manifested as road arch deformation, structural layer cracking, floor voiding, pavement dislocation, muddying, potholes, cracks, and fractures etc., not only destroys the ride comfort and ride comfort, but also makes the vehicle unable to drive fast, failing to achieve the purpose of "fast, safe and comfortable" expressway

Post-construction settlement monitoring is a way to prevent highway hazards. The existing post-construction settlement monitoring is mostly on-the-spot measurement by personnel, which cannot be monitored in real time; if real-time monitoring is required, it needs complex external circuit assistance, which has short life and poor practicability. It is necessary to develop a simple and practical post-construction settlement monitoring device
