In view of the problems of difficult connection and high leakage ratio of waterproofing membrane for underground pipe gallery,this paper puts forward a new construction technology and verifies it.The base treatment and positioning are first carried out,and then the membranes are fixed by multi-point splicing,the side wall and roof of the pipe gallery are reinforced for the second time,and the waterproof is realized through the splicing and sealing of the deformation joint of the bottom plate.The test results show that the leakage ratio of the four test points randomly selected in the two pipe gallery sections is controlled below 3.2,indicating that the waterproof construction technology of the pipe gallery structural engineering designed this time is efficient and simplified with high construction efficiency and strong pertinence,and the recurrent waterproof effect is significantly improved.
