Settlement and Deformation Monitoring System of Expressway Bridges and Culverts

Abstract

The present invention discloses a highway bridge-culvert settlement deformation monitoring system, which comprises: a plurality of observation marks, wherein the observation marks are respectively arranged on the bridge beam portion, each beam bearing platform and each pier of the monitored highway; plural groups of settlement deformation monitoring devices, wherein a group of the settlement deformation monitoring devices is arranged in each observation mark; and PDA forming communication connections with the plural groups of the settlement deformation monitoring devices so as to real-timely receive the information monitored by each group of the settlement deformation monitoring devices. According to the present invention, the positions of the observation marks are arranged on the culvert, the bridge beam portion, the beam bearing platform and the pier of the monitored highway bridge-culvert in the dispersed manner so as to improve the monitoring result accuracy; the GPS modules and the optical fiber sensors are arranged in the observation marks, such that the specific position and condition of the settlement and / or deformation of the monitored highway bridge-culvert can be obtained; and the PDA is the hand-held terminal so as to easy carry, such that the monitoring process is substantially convenient, the monitoring cost is reduced, and the monitoring efficiency is improved.

Description

technical field [0001] The invention relates to a settlement deformation monitoring system. More specifically, the present invention relates to a system for monitoring settlement and deformation of expressway bridges and culverts. Background technique [0002] In the process of highway construction, with the rapid development of transportation, the traffic volume, load capacity and speed of vehicles are constantly increasing, and the phenomenon of overloading is also very serious, which has a great impact on the settlement of bridges and culverts. In-depth research on settlement deformation of bridges and culverts and dynamic tracking detection, And look for its laws, so as to formulate effective prevention and control measures to ensure driving safety. [0003] In recent years, the state has increased investment in infrastructure construction, and road construction has made great progress. With the passage of time, the rapid development of transportation, the traffic volum...

Problems solved by technology

[0003] In recent years, the state has increased investment in infrastructure construction, and road construction has made great progress. With the passage of time, the rapid development of transportation, the traffic volume, load capacity and speed are constantly increasing, and overloading is also very common. Serious, it has a great impact on the settlement of bridges and culverts, and some bridges and culverts exceed the design allowable value within the specified time range, resulting in a decrease in the safety of the bridge

The settlement detection technology of highway bridges and culverts in my country is still at the level of the developed countries in the early or mid-1990s. The detection equipment and detection methods are primitive and backward, which cannot make a comprehensive, rapid and accurate evaluation of the project quality.
