Execution method of waterproof for shield tunnel and waterproof structure

摘要

The present invention fills the gap between the tunneling gravel beans and ground , and between the pores of the gravel beans by filling a non- curable adhesive by a flexible sealant to backfill a tunnel for a long time has elapsed , even when it is possible to prevent cracking or backfill part of the tunnel due to vibrations and shocks by the sealant to minimize the leak and subsidence tunneling can be prolonged the life of the whole as well as a tunnel , which results can significantly reduce the maintenance cost of the tunnel , so that the safety shield tunnel , such as tunnel collapse can be prevented , and moisture resistant construction methods construction structure and to provide for .
