富水区综合管廊预制装配防水关键技术

Key Waterproof Technology for Prefabricated Utility Tunnel in Water Rich Area

针对综合管廊预制装配接口节点易渗漏的情况,结合管廊工程实例,从多道防水设防、可拆式构造、横截面接口防水等角度出发,探讨富水地层预制综合管廊防水施工技术,并初步研究新型防水材料及防水构造在富水地层预制装配综合管廊中的应用情况。

In view of the leakage of the prefabricated joint of the utility tunnel,combined with the engineering example of the utility tunnel,this paper discusses the waterproof construction technology of the prefabricated utility tunnel in the water rich stratum from the perspectives of multi-channel waterproof fortification,detachable structure and cross-section interface waterproofing,and preliminarily studies the application of new waterproof materials and waterproof structures in the prefabricated utility tunnel in water rich stratum.
