摘要
首次在水利水电勘查行业采用水平导向钻进+水平段螺杆马达取心+地球物理测井组合工艺技术,实现了珠江三角洲水资源配置工程狮子洋主航道补充地质勘查,为大直径泥水平衡盾构机的顺利掘进提供了超前地质预报。通过项目的实施,成功验证了深埋长隧道传统垂直点状钻探勘查方式变革为水平线状定位取心综合勘查工艺的可行性,给一些受限于场地、气候、交通、生态、环境保护等因素所带来的无法开展传统钻探勘查工作的重大基建项目带来了新的勘查方法。
This study uses firstly a combination of horizontal-guided drilling and horizontal section screw motor coring as well as geophysics logging techniques in the water conservancy and hydropower exploration industry,realizing supplementary geological exploration of the Shiziyang main channel of the water resources allocation project in the Pearl River delta and providing the geological prediction for the smooth excavation of large diameter slurry balance shield machine.This paper verifies the feasibility of the change of traditional vertical point drilling exploration method for deep-buried long tunnel into horizontal linear positioning coring exploration technology.This exploration method can be applied to the exploration of some major capital construction projects which can not carry out the traditional drilling due to site,climate,transportation,ecology,environmental protection and other factors.
