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
