PE排污管季节性施工及成品保护的注意事项

　众所周知，在市政排污排水系统建设上，常用的有PE排污管及塑钢缠绕管、钢带波纹管等等，这些排污专用管材对于施工环境有一定的要求，那么在施工过程中季节温度环境对于PE排污管的影响是什么呢？接下来润硕给你一一解惑：

PE排污管季节性施工注意事项

　1.雨期施工 　 

　　(1)基坑(槽)周围应设置排水沟和挡水埝，对开挖马道应封闭，防止雨水流入基坑内。

　　(2)沟槽开挖后若不立即铺管，应留沟底设计标高以上200mm的原土不挖，待到下管前再挖至设计标高。

　　(3)电焊施工时，应搭设防雨设施。

　　(4)管道施工完毕后应及时回填，防止漂管事故发生。

　2.冬期施工

　　(1)基坑开挖后及时安管、回填，否则应采取覆盖等措施防止地基受冻。

　　(2)在焊接前先清除管道上的冰雪霜。

大口径PE排污管

PE排污管的成品保护

　　1、缠绕管使用中应尽量避免阳光长期照射。施工过程中没有下槽的管材应避免在阳光下直接照射，以防发生热变形。

　　2、管材存放、搬运和运输时，应采用皮带、吊带或吊绳进行装卸。吊装时应至少有两个节点，严禁穿管吊。

　　3、管材、管件存放搬运时，应小心轻放，排列整齐，不得抛摔和沿地拖拽。

　　4、下管过程中，严禁将管道从上往下自由滚放，应防止块石等重物撞击管身。

　　5、回填土中不得含有石块、砖块及其他杂硬物体，避免划伤管道。

　　以上就是PE排污管在施工过程中环境对于管材影响的注意事项，平时小细节处理的好，施工质量才能得以保障，往往就是一些小细节没有在意到而会引发施工问题。

As we all know, in the construction of municipal sewage and drainage systems, PE sewage pipes, plastic steel winding pipes, steel belt corrugated pipes, etc. are commonly used. These sewage special pipes have certain requirements for the construction environment, so the seasonal temperature environment during the construction process is for PE What is the impact of the sewage pipe? Next, Runshuo will explain to you one by one:

Precautions for seasonal construction of PE sewage pipe

　1. Construction during rainy season 　 

　　 (1) Drainage ditches and water retaining ridges should be arranged around the foundation pit (trough), and the excavation road should be closed to prevent rainwater from flowing into the foundation pit.

　　 (2) If the pipe is not laid immediately after the trench is excavated, the original soil 200mm above the design elevation of the trench bottom shall not be excavated, and it shall be dug to the design elevation before the pipe is lowered.

　　(3) Rainproof facilities should be installed during electric welding construction.

　　(4) After the pipeline construction is completed, it should be backfilled in time to prevent pipe floating accidents.

　2. Winter construction

　　 (1) After the excavation of the foundation pit, it shall be piped and backfilled in time. Otherwise, measures such as covering shall be taken to prevent the foundation from freezing.

　　(2) Remove ice, snow and frost from the pipe before welding.

Large diameter PE sewage pipe

Finished protection of PE sewage pipe

　　 1. The winding tube should be used to avoid long-term sunlight exposure. During the construction process, the pipes without the lower groove should avoid direct sunlight to prevent thermal deformation.

　　2. When the pipes are stored, handled and transported, belts, slings or slings should be used for loading and unloading. There should be at least two nodes when hoisting, and it is strictly forbidden to hang through pipes.

　　3. When storing and transporting pipes and pipe fittings, they should be handled with care, neatly arranged, and not tossed or dragged along the ground.

　　4. It is strictly forbidden to freely roll the pipe from top to bottom in the process of running down the pipe, and prevent heavy objects such as rocks from hitting the pipe body.

　　 5. The backfill soil shall not contain stones, bricks and other hard objects to avoid scratching the pipeline.

　　 The above are the precautions for the environmental impact of the PE sewage pipe on the pipe during the construction process. Usually, the small details are handled well, and the construction quality can be guaranteed. Often, some small details are not paid attention to and will cause construction problems.
