在进行管道安装时.卫隹间楼面被破坏的现象具有相当的普遍性,主要表现在以下几方面。1.各种管道的预留洞口被凿动。在安装管道时,发现预留洞口遗漏或位置不准确,只好直接在楼板上打洞,或将洞口向外扩大。用大锤、钢钎直接砸、凿楼面,致使洞口外围一定范围内的混凝土劈裂、酥松,并产生向四周延伸的小裂缝。
During the installation of the pipeline, the destruction of the defendant’s floor is quite universal, mainly in the following aspects. 1. The reserved holes of various pipelines are indented.
