In real life, we see all kinds of pipe trenches around us sinking after backfilling every day, and it is also a common problem of construction quality. In order to effectively prevent the common problems of falling quality, Rubber Rings Manufacturer introduces the following points that must be strictly implemented :
1. After laying the lower trench, the polyethylene pipe should be covered with fine soil or sand immediately, and the thickness is not less than 30cm to ensure that the polyethylene pipe is not damaged by external forces.
2. For trench backfilling, the bottom of the pipe should be filled first, then both sides of the pipe should be filled, and then backfilled to 0.5m above the pipe. If there is water supply in the ditch, it is necessary to drain it in before backfilling it.
3. The support of the trench should be removed in sequence according to the progress of backfilling under the condition of ensuring the safety of construction. After the vertical piles are removed, the gaps should be filled with sand and soil.
4. The backfill soil on both sides of the pipeline and within 0.5m above the pipe length shall not contain debris, bricks, waste and other debris, and shall not be backfilled with frozen soil.
5. The backfill soil should be layered and compact, each layer should be 20cm, and the pipe should be more than 0.5m, and the machine can be used. The density of each part of the trench should meet the strict requirements.
6. It should be backfilled as soon as possible after the completion of pipeline installation and laying. Because of the large thermal expansion coefficient of PE pipes, it is recommended that the backfill time be selected at a time of the day when the temperature is low.
Through the above introduction, Pe Gasket Manufacturers hopes that you can simply refer to the content of this article in future use.
