Xiangjiang remediation drain pipe jacking construction engineering design is carried out mainly in silty clay stratum, in order to ensure the safety of the construction and the surrounding structures, the water balance theory must be used to strictly control the disturbance of soil around the pipe and the large deformation of the ground surface. While the actual construction between W13 to W15, D1800 pipe were all located in sandy pebble stratum, during the construction process monitoring to the maximum ground settlement reached 457.4 mm, some sections had roof fallen and surface collapse had occurred. The mechanism and causes of surface deformation caused by the construction were summarized and analyzed . And some treatment measures were put forward,such as in the pipe on both sides to design waterproof curtain, to use grouting and backfill in the middle section , at the same time, in the interval of W13~W15 add a new working well to shorten the distance of pipe jacking. The ground subsidence was monitored during process of subsequent pipe jacking construction, the results show that the surface subsidence is controlled within the control range, ensures that the safety of construction and surrounding environment.
