Precise positioning system and method for assisting jacking pipe to pass through space obstacle through radar detection

Abstract

The invention discloses an accurate positioning system and method for assisting a jacking pipe to pass through a space obstacle through radar detection, and belongs to the technical field of building construction. The system comprises at least three radar groups and an upper computer, the radar groups are triangularly distributed on the ground; the radar group comprises a radar host, a receiver and an emitter; the receiver, the transmitter and the upper computer are all in communication connection with the radar host. In the invention, radar groups are triangularly distributed on the ground, oscillation particle waves derived and emitted by an electric field and a magnetic field with radar waves in the same direction and perpendicular to each other in the space are mutually interwoven to form a triangular multi-radar network, and the three-dimensional coordinates of an underground space obstacle are positioned. Therefore, the relation between the actual jacking direction of pipe jacking construction and the position of the space obstacle is confirmed, adjustment of the jacking direction and distance of the pipe jacking is assisted, the problem of conflict and collision between the pipe jacking construction and the pile foundation can be avoided, and safety and smoothness of the pipe jacking construction are guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a radar detection-assisted pipe jacking system and method for precise positioning of space obstacles. Background technique [0002] The pipe jacking construction is carried out in the underground space, and the jacking line often needs to pass through the existing buildings, structures or pile foundations in the project. Restricted by the location of the existing civil works, when the pipe jacking route is narrow, if the direction of the pipe jacking cannot be accurately controlled during the construction process, the construction period will be increased or the project quality will be affected, or serious engineering accidents will be caused. Precise positioning of the incoming line is the best solution for solving space obstacles. Therefore, there is an urgent need for a radar detection-assisted pipe jacking pipe-jacking precise positioning system and method for p...

Limited by the position of the existing civil works, when the pipe jacking route is narrow, if the direction of the pipe jacking cannot be accurately controlled during the construction process, it may increase the construction period or affect the quality of the project, or cause major engineering accidents. The precise positioning of the incoming line is the best solution to solve the problem of crossing space obstacles. Therefore, there is an urgent need for a radar detection-assisted precise positioning system and method for pipe jacking through space obstacles.
