Trenchless directional drilling construction method for pipeline burying channel
The invention relates to a trenchless directional drilling construction method for a pipeline burying channel. The trenchless directional drilling construction method comprises the following steps that 1, pipe distribution is conducted, specifically, hot melting connection is conducted on the end faces of two PE solid-wall pipes; 2, directional drilling is conducted, specifically, a working pit and a receiving pit are manufactured, and a directional drilling machine is adopted for hole drilling; 3, back chambering construction is conducted, specifically, chambering is conducted in a step-by-step chambering mode to form a pipeline; 4, the pipe is pulled back, specifically, the pipe is pulled by adopting a pipe puller; and 5, inspection wells are manufactured, specifically, foundation pits are excavated in the two sides of an effective pipe section, the prefabricated inspection wells are installed, the prefabricated inspection wells are in waterproof connection with the PE solid-wall pipes, and then the foundation pits and the peripheries of the prefabricated inspection wells are backfilled. Only the working pit and the receiving pit need to be excavated in the ground, drilling, chambering and pipe pulling operations are carried out at the positions of the working pit and the receiving pit, and environmental influences such as multiple construction technology procedures, a largeamount of road surface damage and traffic obstruction caused by pipeline open excavation construction can be avoided.
本申请涉及一种用于管道埋设通道的非开挖定向钻进施工方法，其包括如下步骤：步骤一、布管：两个PE实壁管的端面进行热熔连接；步骤二、定向钻孔：制作工作坑和接收坑，采用定向钻机钻进成孔；步骤三、回扩施工：采用逐级扩孔的方式扩孔形成管道；步骤四、回拉管材：采用拉管器拉管；步骤五、检查井制作：在有效管段的两侧开挖基坑，安装预制检查井，将所述预制检查井与PE实壁管做防水连接，随后回填所述基坑和预制检查井周边。本申请只需在地面开挖工作坑和接收坑，在工作坑和接收坑位置进行钻孔、扩孔和拉管操作，可以避免管道明挖施工带来的施工技术工序多、大量路面破坏、阻碍交通等环境影响。
