In this paper, in order to solve the difficulties in the rain pipe construction in jianyu road of yulin city, the pipe - pushing technique for the hand - type tool pipe in the sand soil layer has been researched by experiments in which many practice problems were considered such as the movement and deformation of sand soil, the difficulties for the pipe to enter the scheduled work soil, the collapse of excavation surface, the departure of pipe center and the difficulties to correct this departure. by both the calculations for the stabilities of back - supporting soil body and excavation surface and the theoretical analysis on the reasons for the departure ' s producing, some construction techniques were introduced and adopted in this paper which include not only the change and reinforcement to both the back - supporting soil body and the scheduled work soil body but also the settings of pipe cap, lattice and correcting system on the head of the tool pipe
本文針對榆林市建榆路雨水管道中遇到的技術難題，進行手掘式工具管砂土層頂管法施工技術試驗研究，在研究中考慮砂土層存在的后靠土體移位、變形，工具管難以進入出洞土體，挖掘面易坍塌、管道中心易偏差及難糾偏等問題，通過對后靠土體和挖掘面的穩定計算及偏差產生原因的理論分析，提出並採用后靠土體換填加固，出洞土體換填加固，以及在工具管頭部設置管帽、格柵、糾偏系統等技術措施
