Problems solved by technology

[0007] 1. Manual lifting of the antenna, without professional structure, can not guarantee the straightness of the measuring line, it is easy to produce up and down movement, and the detection result is affected by human factors;
[0008] 2. The excavation position of the face face has construction risks, and the protection measures are poor, which cannot guarantee the safety of instruments and equipment and the personal safety of operators;
[0009] 3. It is time-consuming and labor-intensive to manually set up the antenna, and it cannot guarantee the close-fitting effect with the palm surface, and it is easy to be out of contact with the palm surface, which will affect the signal reception effect

Abstract

The invention discloses a geological radar detection surface adapting device and method for tunnel advanced geological forecast. The geological radar detection surface adapting device comprises a carrying platform, a clamping mechanism, an adapting mechanism and a moving mechanism, a clamping mechanism and an adapting mechanism are arranged on one side of the carrying platform, and a moving mechanism is arranged on the other side of the carrying platform; the clamping mechanism comprises a clamping plate used for fixing a radar antenna, the adapting mechanism comprises an elastic part and an adapting mechanical wheel set, the elastic part and the adapting mechanical wheel set are connected with the clamping plate, and the elastic part is used for applying external force to the adapting mechanical wheel set so as to adjust the radar antenna to move along a measuring line by adjusting the position of the adapting mechanical wheel set. The adaptive mechanism of the combined structure of the spring and the adaptive mechanical wheel set is adopted to adjust the attachment of the radar antenna and the detection surface, so that the radar antenna moves along the detection line, thereby facilitating the receiving of signals, and being suitable for the detection of various types of geological radars such as tunnel faces, secondary linings and the like.

Description

technical field [0001] The invention relates to the technical field of advanced geological prediction of tunnels, in particular to a geological radar detection surface adaptation device and method for advanced geological prediction of tunnels. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The geological conditions encountered in the tunnel construction process are extremely complex, and blind excavation without detection will bring serious construction risks to the tunnel construction, such as causing extremely serious consequences such as landslides, water inrush, and large deformation of soft rock, which will not only affect the progress of the project, Even cause serious casualties and property losses. Therefore, it is necessary to understand the geological conditions of the tunnel excavation site. [0004] Before tunnel excavation,...
