Abstract

Abstract: The stateofart of the laying of waterproofing coil in tunneling is presented. The working principle, technical approach and structural characteristics of the new type of waterproofing coil laying equipment are described. The new type of waterproofing coil laying equipment can replace the conventional waterproofing coil laying platform and can achieve the automatic laying and supporting of the waterproofing coil. The aim to develop the new type of waterproofing coil laying equipment is to reduce the working intensity and cost of the labors engaged in the waterproofing coil laying, to improve the laying efficiency and quality and to ensure the construction safety. 

Key words: tunnel, waterproofing coil, supporting, laying
