Waterproofing and Drainage Construction Techniques for Multi- arch Tunnel Partition Wall

Partition wall waterproofing and drainage is a key procedure during the construction of multi-arch tunnel. It determines the success of tunnel waterproofing and drainage treatment and controls the quality of tunnel works in whole. This thesis introduces in detail the construction scheme, construction procedure, construction methods and technical measures for multi-arch tunnel waterproofing and drainage as reference for similar works through engineering examples, taking "drainage as the main, combining waterproofing with drainage, four lines of defense, three measures, the mutual assistance of strong and weak points, adjusting measures according to local conditions, and comprehensive treatment" as the treatment principles.
