This industry new is going to talk about the notes on installation of agricultural irrigation pipes construction.

There are many details to be paid attention to the installation of all kinds of pipes for agricultural irrigation pipes construction. After all, all kinds of irrigation pipes are equivalent to the blood vessels of the whole water-saving irrigation system. Good construction quality can ensure the smooth completion of the connection of various irrigation components. Then, here Topper LDPE Pipe Manufacturer Co., Ltd will explain to you the precautions during construction’s installation of the main irrigation pipes.

1. It is inevitable that there will be residual water in the main irrigation pipe in use. And it needs to be discharged before winter, otherwise the frozen water will damage the pipeline. Therefore, during the installation, the buried depth of the irrigation pipe end should be greater than 70cm, so that the laid pipeline has a slope greater than 0.002. And the water can be automatically discharged into the drainage well or channel. The excavation width of irrigation pipe trench should not be less than 60cm, and the foundation trench should be flat as far as possible. Moreover, the slope should be carried out according to the regulations.

2. For irrigation pipes with diameter greater than 50 mm, fixed piers shall be added at irrigation pipe ends, bends, slope changes, one-way tee, valve fittings, etc. When the ground slope is more than 20%, or the irrigation pipe diameter is greater than 65 mm, it is better to add a fixed pier every certain length, and the spacing should be less than 20 cm.

3. During the installation of irrigation pipes and pipe fittings, the joints of irrigation pipes shall be reserved for the last buried soil. And the joints without joints can be covered with soil for fixation, so as to facilitate the final completion of the inspection. Generally, it is necessary to conduct comprehensive inspection such as flushing and pressure test to ensure that the installation of irrigation pipes here meets the expected requirements of the project, and then the buried soil can be covered.

4. When the irrigation pipe is covered with soil, it should be noted that both sides of the irrigation pipes should be back-filled at the same time. It is strictly forbidden to fill one side and one side in turn, so as to avoid the unexpected force impact on the irrigation pipes caused by the unbalanced lateral pressure so as to damage the precision.
