Problems solved by technology

The seismic reflection wave method is an important method often used in the advanced geological prediction of tunnels. In this method, the geophone is usually fixed by drilling holes or by gypsum or accelerator. This kind of fixing method is time-consuming and labor-intensive. Carry electric drills, plug-in strips, cables or a large amount of gypsum powder and accelerator, and it is difficult to disassemble. After disassembly, residual gypsum or accelerator is attached to the surface of the detector, which is difficult to clean
In the actual construction environment on site, the surrounding rock is hard, it is difficult to drill holes, and the surface of the surrounding rock is wet and slippery due to water outflow from cracks, making it difficult to paste and fix the geophone
After many field practices, it is concluded that the time required for the fixed installation of the geophone occupies 40-50% of the working hours of the entire tunnel's advanced geological prediction, resulting in the problems of low detection efficiency and high detection cost

Abstract

The invention discloses a quickly fixable wireless detector device. The detector device comprises a cylindrical shell; a wireless communication apparatus is mounted in the cylindrical shell to realizereal-time return of seismic data; one end of the cylindrical shell is connected to a three-component detector through a two-stage spring shock absorber; an uncovered cylindrical protective cover is arranged outside the three-component detector, and the three-component detector is connected to the wireless communication apparatus through a data transmission line; and the other end of the cylindrical shell is connected to a telescopic apparatus, which is connected to a magnetic disc through a spherical universal joint which can be fastened by a rotary knob, thus realizing fixation with a trolley.

Description

technical field [0001] The invention relates to a geophone device for a TBM tunnel, in particular to a radio communication geophone device suitable for seismic detection when the TBM is shut down. Background technique [0002] In today's tunnel construction, the tunnel boring machine has been widely used, and the advanced geological prediction of the tunnel is an important guarantee for its safe construction. The seismic reflection wave method is an important method often used in the advanced geological prediction of tunnels. In this method, the geophone is usually fixed by drilling holes or by gypsum or accelerator. This kind of fixing method is time-consuming and labor-intensive. Carry electric drills, plug-in strips, cables, or a large amount of gypsum powder and accelerator, and it is difficult to disassemble. After disassembly, residual gypsum or accelerator is attached to the surface of the detector, which is difficult to clean. In the actual construction environment ...
