某一净环泵房水池,混凝土强度等级为C30,抗渗等级不低于P8,工程施工时,在池壁-2.120m处留设水平施工凹缝。但因施工操作不当,造成部分凹缝未形成或未能迭到标准,且中间3道隔墙施工缝处未采取防水措施,为防水混凝
A net ring pump room pool, the concrete strength rating of C30, impermeability rating of not less than P8, construction, the wall at -2.120m leave horizontal construction concave. However, due to improper construction and operation, resulting in some of the indentation has not formed or failed to reach the standard, and the middle three partitions at the construction joints did not take waterproofing measures for waterproofing coagulation
