基于跨孔CT和HDD的地下障碍物探测方法
An underground obstacle detection method based on cross-hole CT and HDD
摘要
Abstract
To overcome the problems of low positioning accuracy and inaccurate detection of cross-hole earthquake wave tomography ( CT) , an obstacle detection method for trenchless underground lin-ear structure is proposed by integrating cross-hole earthquake wave CT technology and horizontal di-rectional drilling ( HDD) technology. Firstly, drilling and laying pipes along the longitudinal direction of underground structure are complemented with the aid of HDD technology. Then, the underground obstacles in the trenchless zone are detected by use of cross-hole earthquake wave CT technology. To verify the feasibility of the proposed method, a water main pipe of pipe-jacking construction is taken as an example to detect the distribution of obstacles. The result shows that the proposed geophysical prospecting method has a high precision of detection and good application prospects.关键词
