污水处理厂粗格栅与细格栅防水混凝土施工技术

Waterproof Concrete Constructing Technique in the Thick-Case-Bar and Thin-Case-Car Project of Sewage Farm

石家庄市桥东污水处理厂粗格栅与细格栅工程,结构复杂,施工难度较大,采用补偿收缩混凝土作结构自防水,同时用膨胀加强带取代后浇带,取得缩短工期、避免裂渗的良好效果。

The thick- case- bar and thin- case- bar project of Shijiazhuang Qiaodong sewage farm is characterized by complex structure and hard constructing. By adopting shrinkage- compensating concrete to make structure self- water- proof, replacing post- pouring belt by expansion strengthening belt, a good effect of short construction period and crack- permeability avoiding was obtained.
