Construction method for water-stop wall of tunnel pipe-jacking outlet
The invention relates to the field of tunnel pipe-jacking construction, in particular to a construction method of a water-stop wall at a tunnel pipe-jacking outlet, which comprises the following steps: arranging the water-stop wall at the tunnel pipe-jacking outlet, grooving the water-stop wall at a soil layer part by using a hydraulic grooving machine, and auxiliary grooving the water-stop wall at a rock layer part by using a percussion drill; after the groove is formed, a groove forming machine is used for conducting hole cleaning on the groove, and pump suction reverse circulation is used for conducting hole cleaning on the groove; pouring the prepared slurry into the cleaned groove by using a conduit method; and after pouring is completed, the tunnel jacking pipe outlet water stop wall is obtained. The construction method of the water-stop wall is simple in construction and effectively suitable for different geologies, and compared with an existing water-stop method, the constructed water-stop wall is higher in stability and better in water-stop effect.
本发明涉及隧道顶管施工领域，具体涉及一种隧道顶管出洞口止水墙的构建方法，包括：在隧道顶管出洞口设置止水墙，所述止水墙在土层部分使用液压成槽机成槽，在岩层部分使用冲击钻机辅助成槽；成槽后使用成槽机对槽进行扫孔，使用泵吸反循环对槽进行清孔；对清孔后的槽使用导管法和配置好的浆液进行灌注；灌注完成后得到隧道顶管出洞口止水墙。本发明提供的止水墙构建方法施工简单，有效适用于不同地质，所构建的止水墙相较于现有的止水方法稳定性更高、止水效果更好。
