As the weather gets colder, the requirements for building materials in the modern construction industry continue to improve, and the commonly used PE pipe requirements will also increase. When we carry out the construction of the pipe, we will alter the construction requirements according to environmental factors, so that the pipe can meet the use standards and meet the construction requirements of the pipe.
Thus next, China HDPE parts factory will take you to understand the construction method of PE pipe in a low temperature environment:
1. Take excellent anti-icing measures
During the construction of PE pipes, we should take anti-icing measures: in the cold winter weather, effective anti-icing measures should be taken to excavate the trench, so as to avoid affecting the installation and construction of the pipeline due to icing of the excavated trench. Some simple grass curtains can be laid over the excavated trench to avoid freezing.
2. Make a temporary drainage system for PE pipes
Ensure that on-site construction can be timely drainage, to avoid the accumulation of water in the construction process. In winter, once there is water on the construction site is easy to freeze, affecting the construction progress, and then the water will wash the excavation of the trench caused by the slope slide and other consequences.
3. Drainage measures for PE pipe grooves should be taken
Groove should be timely drainage together, to prevent water bubble tank. Once the water is in the groove, should take immediate measures to drainage, the softened soil bubble removed, filled with sand and stone, do a good job of trench soil treatment, is prohibited in the trench with water operations.
4, shorten the construction period
In winter, when the temperature is low, PE pipe construction personnel should excavate the trench quickly and backfill quickly to prevent the impact of icing on installation and backfill.
5. Take measures to prevent the pipe from floating
Winter construction should be backfilled to the top of the pipe more than one times the height of the pipe diameter. When the pipeline is installed and the soil is not returned, once it is exposed to blisters, the middle line and bottom elevation of the pipe should be retested and the surface inspection should be carried out.
PE pipe is commonly used in construction, so when we carry out low-temperature construction, we should first take protective measures for the trench to prevent icing phenomenon, resulting in pipe freezing and cracking, which will affect the subsequent use of the pipe.
