To improve the impermeability of the pipeline, the key problem of impermeability during pipe-jacking was studied in respect of its use scenario and own structure. Then, opening angle and opening value was introduced to describe the opening state and explain the effect of improving the linear accuracy of the pipe line for anti-seepage of pipe jacking. The all-weather linear control system based on laser measurement system was introduced and applied successfully. Its effect in improving linear accuracy and inducing leakage passage was demonstrated. The relationship between opening length and bearing capacity was established. For JCCP pipe of Jinjiang reclaims water pipe project, the water pipe joint is optimized aimed based on lifting device and airproof testing. The successful implementation of the project confirms the feasibility of the above anti-seepage technology of mechanical pipe jacking. The above study demonstrate that all-weather linear control system and airproof testing based on lifting device is effective for anti-seepage.
