EXECUTION METHOD OF WATERPROOF FOR SHIELD TUNNEL AND ITS STRUCTURE

摘要

A shield tunnel waterproofing constructing method is provided to prolong the lifetime of the whole tunnel whole and prevent safety accident including the tunnel radioactive decay etc. A shield tunnel waterproofing constructing method is constructed as follows. Gravel(20) is filled in the outer circumference of the tunneling(10) and gap interval of the ground through a plurality of inlet ports(12) passing through in the installed tunneling and is formed and it fills back. The inlet port is prevented with the separately equipped stopper(30) and the gravel is not ejected. A waterproof agent(40) which is pliable through the injection hole(32) formed in the stopper with the non-curing adhesion is injected. An air gap interval of the chips is filled up and it does not make generated by the tunneling inside. A bolt(B) is screwed in the injection hole and the waterproof agent is not issued.
