输水隧洞衬砌混凝土常见质量通病及防止措施

On Common Defects of the Lining Concrete Quality in Water Diversion Tunnel Project and Measures to Prevent Them

随着山西大水网建设的规划实施,引调水隧洞工程越来越多,隧洞二次衬砌支护的质量好坏,直接影响着隧洞输水的整体质量。文中就东山供水工程5#-7#隧洞二次衬砌工序质量控制经验为例,阐述了对衬砌各工序质量控制的要点、可能导致的质量通病以及防止措施的一些观点。

At present,more and more water diversion and inter-basin water transfer tunnel projects are being constructed in pace with conducting the planning of Shanxi Great Water Network Project construction,and the good and bad of the second-time lining and support in tunnel will directly impact the whole quality of water diversion.Taking the experience to control the second-time lining quality in No.5, No.6 and No.7 tunnel of Dongshan Water Supply Project as an example, the paper expounds main points of controlling the quality of every lining working procedure, the common quality defects that may occur and some opinions of prevention measures.
