Precautions during the loading and unloading process of round plastic blind ditch and during construction



The circular plastic blind ditch, also known as the composite geotechnical drain pipe, is a three-dimensional porous drainage material structure formed by the hot melt of the modified synthetic resin to form a frame. The outer layer is covered with a layer of permeable geotextile, and the muddy water is filtered by the outer geotextile. The clear water enters the circular plastic blind ditch tube and is discharged.



Transportation handling and storage: during transportation and loading and unloading. It is necessary to take it lightly, do not throw it, avoid mixing and mixing with sharp objects, avoid violent impact, wear flat rubber shoes when unloading the car, lift two people, two people in the car to lightly step on, the two are slow in the car Slowly splicing, smooth and lightly placed on the ground, the product should not be stored in the open air, and should avoid long-term exposure and heavy pressure of sunlight. Keep away from heat sources greater than 15cm and cover the tarpaulin when storing.



Construction: After excavating the curved trough according to the design, the bottom of the canal should be cleaned and leveled, and then the fine sand or powdered soil should be backfilled for 15cm. Then the two people lift the blind ditch and gently place it in the channel. The two butt joints are used to cover the geotextile. When turning the joint, use a hacksaw to cut the groove at one end of the joint at both ends into a 45-degree angle to form a 90-degree cross-section space, and then put the geotextile on the joint and then backfill the finer 75cm or more. Sand or dust, gently spread, avoid using machinery and equipment compaction, to avoid blind ditch directly contact with gravel, carefully laid to avoid rough construction.



To sum up the above points, we can achieve fine, civilized, safe, scientific construction, achieve a good drainage effect, and meet engineering requirements.
