HDPE双壁波纹管由于具有耐腐蚀、内壁平滑流量大、以及使用时间长等特点,在管道施工的工程中非常受欢迎。很多发达国家都已经实现了HDPE双壁波纹管的普及应用了,现在我们国家也在大力的推广使用。现在很多城市甚至村镇都在更换排水管道,所以,管道工程的施工就变得非常重要。今天,我们就来了解一下,HDPE双壁波纹管的工程施工有哪些技术要点?
HDPE Double wall corrugated pipe is very popular in pipeline construction because of its corrosion resistance, smooth inner wall, large flow rate and long service time. Many developed countries have achieved the popularization and application of HDPE Double wall corrugated pipe, and now our country is also vigorously promoting the use. Now many cities and even villages and towns are replacing drainage pipes, so the construction of pipeline engineering has become very important. Today, we will learn about the technical points of HDPE Double wall corrugated pipe construction?

1、施工人员首先应该熟悉图纸,尤其是工程负责人,要掌握全局,更加应该熟悉工程的每个步骤。在施工前,应该每隔100米左右设置一个水准高程基准点,设置一个准确的水准高程控制网,有利于后续管线施工的测量。还需要经闭式检验和计量正确之后,必须符合国家标准才能施工。
1. The construction personnel should be familiar with the drawings, especially the person in charge of the project. They should master the overall situation and be familiar with every step of the project. Before the construction, a leveling datum point should be set every 100m or so, and an accurate leveling and elevation control network should be set up, which is conducive to the measurement of subsequent pipeline construction. After the closed inspection and measurement are correct, the construction must meet the national standards.
2、HDPE双壁波纹管管沟的开挖,需要注意的是管道斜坡的科学合理理性。应特别注意不要超过沟槽挖过开挖断面仔细回填夯实,低洼严禁积水,并不能使用废土和污泥等腐质图夯填。

2. In the excavation of HDPE Double wall corrugated pipe trench, it is necessary to pay attention to the scientific rationality of the pipeline slope. Special attention should be paid not to exceed the trench excavation cross-section, careful backfilling and compaction, low-lying water is strictly prohibited, and the use of waste soil and sludge and other rotten map compaction.
3、HDPE双壁波纹管的存放问题。在管道施工结束前,如果将管材运入工地,将会占用交通通道。但是,如果是埋入土管悬挂安装方式,又要浪费时间将管材挖出。因此,在管道铺设完成之前,应该妥善的存放HDPE双壁波纹管。
3. Storage of HDPE Double wall bellows. Before the end of pipeline construction, if the pipe is transported to the construction site, it will occupy the traffic channel. However, if it is buried in the soil pipe hanging installation method, but also waste time to dig out the pipe. Therefore, HDPE Double wall corrugated pipe should be properly stored before the completion of pipe laying.
4、HDPE双壁波纹管的闭水试验。应仔细检查各个管道有无沙眼裂缝,管口连接处是否严密,如不符合质量要求,可用细砂浆修补,水泥浆刷浆补填。闭水管段先不要急着回填,需要等到闭水试验通过以后在进行回填。
4. Closed water test of HDPE Double wall bellows. Carefully check whether there are sand hole cracks in each pipe and whether the joint of pipe mouth is tight. If it does not meet the quality requirements, it can be repaired with fine mortar and filled with cement slurry. The closed water pipe section shall not be backfilled in a hurry, but shall be backfilled after the closed water test is passed.
5、HDPE双壁波纹管沟槽回填。在回填沟槽时,管沟内不得有积水,不得使用腐殖土,土壤和污泥等垃圾土回填管沟。
5. HDPE Double wall corrugated pipe trench backfilling. When the trench is backfilled, there shall be no ponding in the trench, and no humus soil, soil and sludge shall be used to backfill the trench.
以上就是HDPE双壁波纹管在施工过程中的技术要点,要想能够顺利合格的完成管道工程,以上几点是必须按要求做到的。
The above are the technical points of HDPE Double wall corrugated pipe in the construction process. In order to successfully complete the pipeline engineering, the above points must be done according to the requirements.
