Abstract

The invention relates to a shield construction system based on a ground penetrating radar, comprising a shield machine and the ground penetrating radar, wherein the shield machine is connected with the ground penetrating radar through a signal transmission system combining a wireless signal transmission mode with a wired signal transmission mode; the ground penetrating radar and a wireless signal transmission module of the signal transmission system adopt a DC power supply system for a power supply; the power supply of the DC power supply system is obtained by carrying out voltage and frequency transformation processing on commercial AC; and the ground penetrating radar is arranged in front of a cutterhead of the shield machine by adopting a specially designed projection structure. The invention has innovative application of installing the ground penetrating radar on the cutterhead of the shield machine for detecting front geology, can enable the ground penetrating radar to be used for normally operating in an underground construction environment without being damaged by external conditions, effectively ensure the radar power supply, also realize good information transmission through the ground penetrating radar and a computer inside a control chamber of the shield machine and be widely used in the fields of various underground constructions and tunnel constructions, and the like.

Description

technical field [0001] The invention relates to a shield construction system, in particular to a ground penetrating radar-based shield construction system. Background technique [0002] The situation ahead of shield tunneling construction is complex and changeable, and there are often unfavorable geological factors and unknown buried objects, such as municipal pipelines, artificial structures, water bubbles, air bubbles, gravel, shipwrecks, etc. These factors will cause landslides and water gushing in the working face, which will affect the speed of tunnel excavation, delay the construction period, and increase construction costs; in severe cases, it will cause equipment damage and casualties, and the consequences will be unimaginable. Therefore, it is necessary to conduct advanced detection and identification of the geological conditions in front of the shield working face, provide more accurate data for construction, guide shield excavation, and avoid risks. [0003] The ...
