Highway pavement settlement monitoring and early warning system

Abstract

The invention discloses a highway pavement settlement monitoring and early warning system, which belongs to the technical field of settlement monitoring and early warning. The highway pavement settlement monitoring and early warning system comprises a settlement detection unit, an auxiliary detection device, a relay device and a monitoring center, wherein the settlement detection unit comprises multiple displacement sensors, and the multiple displacement sensors are located at the lower end of the pavement and located in a roadbed; the auxiliary detection device comprises a video acquisition device, an automobile weighing device, a vehicle counting device and an earthquake detection device; the earthquake detection device is located at the lower end of the pavement and located in the roadbed; and the relay device comprises a data acquisition unit, a wireless transmission unit and an emergency communication device. The settlement of the highway pavement can be monitored in real time; due to acquisition of multiple data, a worker can analyze the causes of pavement settlement in many ways more conveniently, comprehensive understanding of monitored road sections by a monitoring centeris realized, and hidden safety hazards caused by settlement of the highway can be eliminated in time.

Description

technical field [0001] The invention relates to the technical field of settlement monitoring and early warning, and more particularly, to a highway road surface settlement monitoring and early warning system. Background technique [0002] Expressways are high-grade roads. The Ministry of Communications of the People's Republic of China "Technical Standards for Highway Engineering" stipulates that expressways refer to "highways that can accommodate an average annual day and night passenger car traffic of more than 25,000 vehicles, are dedicated to separate high-speed vehicles, and have full access control". Although different countries have different names for highways, they all refer to highways with more than 4 lanes, two-way separated driving, complete control of entrances and exits, and all use of interchanges. In addition, in many countries, the direct trunk lines that partially control entrances and exits and not all use grade-overs are also called expressways. General...

Problems solved by technology

[0004] The existing pavement settlement monitoring technology is not perfect enough. Generally, settlement observation columns or settlement observation points are used for observation. The judgment of settlement requires staff to patrol, which will consume a lot of manpower and material resources, and the accuracy is poor, and sometimes it is not timely. Dealing with the subsidence of the road surface will cause faults or subsidence of the expressway. Moreover, the location of many expressways is relatively remote, and it is difficult for the staff to perform a completely accurate inspection. Even if there are corresponding sensors, there is no corresponding early warning system. hard to function
