SELF ADHESIVE BUTYL WATERPROOFING SHEET AND THE METHOD FOR ASSEMBLING CABLE TROUGHS FOR THE BRIDGES OF HIGH-SPEED RAILROAD BY USING THE SELF ADHESIVE BUTYL WATERPROOFING SHEET

摘要

PURPOSE: A self-adhesive butyl waterproofing sheet and a method for assembling cable troughs for a rapid-transit railway bridge using the same are provided to precisely adjust the positions of PC concrete members and meshes. CONSTITUTION: A self-adhesive butyl waterproofing sheet(1) comprises a butyl sealing material(2), a mesh(3), and a release paper(4). The butyl sealing material is formed in a sheet shape and comprises a butyl rubber material. The mesh is attached on one surface of the butyl sealing material. The release paper is attached on the other surface of the butyl sealing material and can be removed by a worker. When compressive force is applied to the mesh, the mesh can be embedded in the butyl sealing material.
