本文通过工程案例,介绍了地下工程因底板配筋率偏低或施工冷缝、后浇带振捣不密实或未加止水钢板、变形缝处误用橡胶止水带、外墙护壁柱处未增加温度筋、顶板过早上荷载等原因造成的渗漏,并给出解决方案,有助于提高地下工程结构自防水质量。 This article through the project case, introduced the underground engineering due to the low reinforcement ratio of the floor or construction of cold joints, after pouring with vibrating not dense or no water plate, the deformation of the seam at the wrong place with rubber water stop, wall plinth Did not increase the temperature of the tendons, roof load caused by premature leakage and other reasons, and give solutions to help improve the quality of self-waterproof underground structures.
