Problems solved by technology
[0003] During the use and monitoring process of traditional monitoring methods, the basic principle is to realize the summary of the law of roadway displacement convergence by monitoring the displacement dynamic data of a certain point in the roadway section. Under certain conditions, it can meet the rough monitoring law of the roadway. The data feedback from a single point has a certain one-sidedness, which can easily cause data errors, lead to the failure of the monitoring effect, and even cause unpredictable safety hazards

The invention relates to the technical field of roadway surface area convergence continuous monitoring, and provides a roadway surface displacement monitoring device and method for regional multi-point continuous measurement. The device comprises a monitoring main body, a metal rod body, and a connecting round wheel, wherein the monitoring main body comprises an infrared range finder and an anglerotation control unit, the range finder measures the linear distance from a roadway side, the angle rotation control unit controls the rotation and the rotation angle of the range finder in the horizontal direction, one end of the connecting round wheel is connected to the metal rod body, and the other end of the connecting round wheel is connected with the monitoring main body. According to the invention, the horizontal corner and the distance between the two sides of the roadway are recorded according to the rotating position of the distance measuring instrument, roadway side displacement deformation monitoring within the L-distance area range in front of and behind the roadway side is achieved according to each set of corner and distance, equivalent displacement of each set of data is collected and calculated, and accurate measurement of the deformation amount and the deformation rate within the roadway side measuring station area range is achieved; and the device is ingenious in structure and continuous in monitoring, deformation monitoring in a regional range is realized, and one-sided and error of single-point or single-section monitoring is reduced.
Description
technical field [0001] The invention relates to the technical field of continuous monitoring of roadway surface area convergence, in particular to a roadway surface displacement monitoring device and method for regional multi-point continuous measurement. Background technique [0002] The section of the roadway is formed after excavation, and the basic stability of the roadway space can be realized under the interaction between the anchor support body and the surrounding rock. With the help of a series of equipment for measuring the displacement convergence of the roadway section, the expression of the displacement change state of the roadway is the best way to investigate the roadway section on site. One of the main means of steady state. The methods currently used to monitor the surface displacement of the roadway mainly include the steel tape measurement method, the measuring gun monitoring method and the measuring rod monitoring method. [0003] During the use and monit...
