With the continuous improvement of building materials requirements in the modern construction industry, the requirements for commonly used PE pipes will also increase. When we construct pipes, we will change the construction requirements based on environmental factors to meet the usage standards and construction needs of pipes. So, let's learn about the construction methods of PE pipes in low-temperature environments:
1. When constructing PE pipes, we should take anti icing measures: in cold winter weather, effective anti icing measures should be taken for excavated trenches to avoid the impact of ice on pipeline installation and construction. Simple grass curtains can be laid on top of the excavated trench to prevent it from freezing.
2. Establish a temporary drainage system for PE pipes: Ensure timely drainage during on-site construction to avoid the accumulation of accumulated water during the construction process. In winter, if there is accumulated water on the construction site, it is easy to freeze, affecting the construction progress. Additionally, accumulated water can wash away excavated trenches, causing slope sliding and other consequences.
3.Take proper drainage measures for PE pipe trenches:timely drainage should be carried out in the trenches to prevent water accumulation from soaking in the trenches.Once water accumulates in the trenches,immediate measures should be taken to drain it,remove the softened soil layer affected by the soaking,fill it with sand and gravel,and treat the soil layer of the trenches properly.It is strictly prohibited to work with water in the trenches.
4.Shorten the construction period:In winter when the temperature is low,PE pipe construction personnel should excavate trenches quickly and backfill quickly to prevent the impact of icing on installation and backfilling.
5.Take measures to prevent pipe floating:During winter construction,backfill soil to a height greater than twice the pipe diameter above the top of the pipe.When the pipeline installation is completed and the soil has not been returned yet,if it encounters water bubbles,the elevation of the middle line and bottom of the pipeline should be remeasured and visually inspected.
PE pipes are frequently used in construction,so when we are carrying out low-temperature construction,we must first take protective measures for the grooves to prevent freezing and cracking of the pipes,which will affect the subsequent use of the pipes.
