Problems solved by technology

[0005] (1) The advanced seismic wave detection system based on wireless communication has a low data transmission rate and poor anti-interference ability, which is not suitable for long-distance large-capacity data transmission, and cannot display the data collected by the geophone in real time;
[0006] (2) Some detection systems only use single-component geophones, which cannot obtain seismic wave waveforms in the x/y/z directions of the tunnel side wall, and the number of geophones is very limited and cannot be expanded;
[0007] (3) The internal storage space of most detection systems is very limited, and data acquisition cannot be

Abstract

The invention discloses a seismic wave advanced detection system embarked on a tunnel boring machine and a method thereof. The seismic wave advanced detection system embarked on a tunnel boring machine includes a pilot sensor, wherein the pilot sensor is fixed on a cutterhead of the tunnel boring machine, and a data receiver of the pilot sensor is arranged in a man cabin at the back of the cutterhead of the tunnel boring machine; the pilot sensor and the data receiver of the pilot sensor perform data communication in a wireless mode; the data receiver of the pilot sensor and a host of the detection system perform data transmission through a cable of the pilot sensor; a plurality of three-component geophones are arranged in a certain range at the back of the cutterhead of the tunnel boring machine, are divided into two groups to be arranged at the walls of two sides of the tunnel, and can perform data transmission with the host of the detection system through a cable of a detector; aplurality of hydraulic focuses are arranged at the back of the cutterhead of the tunnel boring machine, and are connected with a hydraulic focus control system; and after the host of the detection system receives a trigger signal from the hydraulic control system, synchronous data acquisition of all the three-component geophones can be realized through a time sensitive network.

Description

technical field [0001] The invention relates to an advanced seismic wave detection system and method mounted on a tunnel boring machine. Background technique [0002] Compared with drilling and blasting tunnel construction, tunnel boring machine construction has significant advantages such as fast excavation speed, high hole quality, high comprehensive economic benefits, safe and civilized construction, etc. With the continuous development of tunnel construction in my country, tunnel boring machine will also be obtained More and more applications. However, the adaptability of tunnel boring machines to geological conditions is poor. Geological disasters such as water and mud inrush and landslides have brought major challenges to the construction safety of tunnel boring machines, which can easily lead to major accidents such as machine jams and even machine crashes. Therefore, it is of great significance to find out the unfavorable geological bodies existing in front of the tu...
