摘　　要：鉴于目前大口径钻井固管工艺容易造成固管不密实,管道壁后空洞等问题,在某矿山排水钻孔的施工过程中,通过研制的单向阀完成了排水管的安装和固管,解决固管不密实及固管后残留物较多的问题。本文主要介绍了单向阀的结构及作用,总结了一项利用单向阀完成大口径排水管的安装和固管工艺,可为今后类似工程施工提供经验和参考。In view of the problems caused by the current solid pipe technology of large diameter drilling,such as nondense pipe and hole behind the pipe wall,the drainage pipe was installed and fixed through the developed check valve during the construction of drainage drilling in a mine,which solved the problems of non-dense pipe and more residue after the solid pipe.
