排水管道堵塞问题的处理

室内排水管道堵塞是建筑安装工程施工中常见的一种质量通病,是管道安装与土建施工配合难以解决的老问题。在土建与安装交叉施工中,管道被堵塞的事例很多,特别是卫生间排水管口与地漏更为严重。即使管道安装后,管口用水泥砂浆封闭,还往往被人打开,作为清洗水泥及平整地面的污水排出口。

Indoor drainage pipe blockage is a common quality problem in the construction and installation of engineering, and it is an old problem that the pipeline installation and civil engineering construction are difficult to solve. In the cross construction of civil engineering and installation, there are many cases of pipe blockage, especially the toilet drain pipe and floor drain are more serious. Even after the pipe is installed, the pipe mouth is closed with cement mortar and is often opened as a sewage discharge port for cleaning cement and leveling the ground.

为了避免交叉施工中造成管道堵塞现象,在管道安装前,除应认真疏通管腔,清除杂物,合理按规范规定正确使用排水配件;安装管道时,应保证坡度,符合设计要求与规范规定及排水管口采用水泥砂浆封口等措施外,还必须采取如下多种技术措施以防止管道堵塞:

In order to avoid the phenomenon of pipeline blockage in cross construction in the pipeline before installation, should carefully dredge the lumen, remove debris, reasonably according to the standard provisions of the proper use of drainage fittings; pipeline installation, should guarantee the slope, comply with the design requirements and specifications and the drainage pipe using cement mortar sealing measures, must also take a variety of techniques are as follows measures to prevent pipe blockage:

由于建筑结构需要原因,当立管上设有乙字管时,应根据规范要求,在乙字管的上部设检查口以便于检修;当设计无要求时,应按施工及验收规范规定,在连接2个及2个以上大便器或3个及3个以上卫生器具的污水横管设置清扫口,在转角小于135度的污水横管上,设置检查口或清扫口;

Since the building structure need reason, when the vertical pipe is provided with a sigmoid pipe, according to the specification requirements, a check in the upper sigmoid pipe to facilitate maintenance; when no design requirements, in accordance with the provisions of code for construction and acceptance of, in connection with 2 and more than 2 stool or 3 and 3 the sanitary ware sewage horizontal pipe cleaning port, the angle is less than 135 degrees on the sewage pipe, set up checkpoints or cleaning the mouth;

排水管道安装时,埋地排出管与立管暂不连接,在立管检查口管插端用托板或其他方法支牢,并及时补好立管穿二层的楼板洞,待确认立管固定可靠后,拆除临时支撑物,此管口应尽量避免土建施工时作为临时污水排出口。在土建装修基本结束后,给水明敷支管安装前,对底层及二层以上管道作灌水试验检查,证实各管段畅通,然后用直通套(管)筒将检查口管与底层排出管连接。

Installation of drainage pipes, underground discharge tube and the vertical tube is not connected with end plate or other tube inserted in the riser inspection method of a prison, and promptly fill vertical pipe through the floor hole two layer, confirming that the riser is fixed and reliable after removal of temporary supports, the boss should try to avoid civil construction as a temporary sewage discharge port. In the construction decoration basically completed, before the installation of water supply pipe for irrigation on the surface, test on the bottom and two floors above the pipe, the pipe that is smooth, and then through the sleeve (tube) tube will check the outlet pipe and the bottom discharge pipe connection.
