Method for enabling small-diameter pipeline to downwards penetrate through existing underground structure
The invention discloses a method for enabling a small-diameter pipeline to downwards penetrate through an existing underground structure. The method comprises the following steps that a sleeve is arranged on a construction pipeline path in a driving mode; the soil body in the casing pipe is removed; a construction pipeline is arranged in the sleeve in a penetrating mode, and a gap between the outer wall of the construction pipeline and the inner wall of the sleeve is blocked; according to the construction method, the casing pipe is arranged firstly, then the soil body in the casing pipe is removed, construction is conducted on the premise that casing pipe supporting is achieved, safety and reliability are achieved when excavation is conducted on the path where the construction pipeline is located, collapse and other dangerous conditions are avoided, and it is guaranteed that construction is conducted safely and smoothly.
本发明公开了一种小直径管道下穿既有地下构筑物的方法，包括以下步骤：在施工管道路径上打设套管；将所述套管内的土体清除；将施工管道穿设在所述套管内，并对所述施工管道外壁和所述套管内壁之间的缝隙进行封堵；本发明通过先打设套管，然后清除套管内的土体，使得在具备套管支护的前提下进行施工，使得在对施工管道所在路径进行开挖时安全可靠，不会产生塌方等危险情况，保证施工安全顺利的进行。
