GLP-150水平钻孔机主要用于砂质和土质地层中钻进水平孔的施工机具。投放市场以来已经取得实用效果。本文主要介绍该机在尾矿坝排渗加固工程中的应用。在已建坝中。特别是我国早期修建的尾矿坝,通常因浸润面很高而大大降低了坝体的稳定性,尤其是在地震动力作用下,坝体的稳定性受到明显的破坏。冶金部门有近二百座尾矿坝,不同程度存在着这样的问题。而且,随着使用年限的增长,浸润面越接近设计坝高,问题暴露得越突出,甚至造成垮坝,如黄梅山尾矿坝。水电部南京水利科学研究院土工所,将在滑坡防治中曾采用的方法,引用於坝体排渗加固中。即在坝体下部设置水平排渗管道,再用竖井集水和沟通水平层,形成自流排渗降低浸润面。称之为水平、垂直联合自流排渗加固法。土工所的科研人员
GLP-150 horizontal drilling machine is mainly used for drilling horizontal holes in sandy and earthy formations of construction equipment. Has been put on the market has achieved practical results. This article mainly introduces the machine in the tailing dam drainage seepage reinforcement engineering application. In the dam has been built. Especially, the tailings dam built in our country early is usually greatly reduced the stability of the dam due to the high infiltration surface, especially the stability of the dam under obvious earthquake damage. There are nearly 200 tailings dams in the metallurgical sector, varying degrees of such problems. Moreover, as the service life increases, the closer the infiltration surface is to the design dam height, the more prominent the problem is exposed and even cause a collapse such as the Huangmeishan tailings dam. Ministry of Water Resources, Nanjing Institute of Hydraulic Research Institute of geology, landslides will be used in the prevention and control methods used in the dam drainage and reinforcement. In the lower part of the dam, a horizontal draining pipeline is set up, and then the shaft collects water and communicates with horizontal layers to form a gravity infiltration and infiltration surface. Known as horizontal, vertical joint gravity drainage reinforcement method. Geotechnical research staff
