THE INNER WATERPROOFING METHOD OF WET UNDERGROUND STRUCTURES WITH THE PERFORMANCE AS AN ELEVATION OF ADHESIVE STRENGTH AND COPING WITH CRACK AND MOVEMENT AND WATERPROOFING STRUCTURE THEREOF

摘要

The present invention relates to the waterproofing method of the underground wet concrete structure and its waterproof layer structure to improve the crack response and adhesion strength, the object of the present invention is to form a primary waterproof layer and to block moisture by using a base adjustment material having waterproof performance Promoting adhesion strength and durability due to this, and applying underground double crack countermeasure system of stress dispersing layer and crack following waterproofing layer containing hydrophilic PVA fiber to provide crack proofing method and waterproof layer structure It is.;The configuration of the present invention is based on the application of a low elastic and high adhesion strength material (base adjustment layer) having strong adhesion regardless of the moisture inside and outside of the substrate and the responsiveness of the substrate to improve the elastic waterproof layer (watertight elastic waterproof layer) and adhesion strength. Its technical features are the underground waterproofing method and waterproof layer structure, which are applied to the wet ground while securing the adhesion strength of the ground surface by applying the adhesion strength improvement system of the intermediate buffer organic buffer layer of the low elastic layer (base adjustment layer) .
