Scope of application of plastic blind ditch
1) Reinforcement and drainage of road and railway subgrade shoulders;
2) Drainage of tunnels, subway underground passages, and underground freight yards;
3) Soil and water conservation for hillside and side slope development;
4) Vertical and horizontal drainage of various retaining walls;
5) Slippery drainage;
6) Drainage of ash piles in thermal power plants. Drainage of landfill works;
7) Drainage of resting green spaces such as sports fields, golf courses, baseball fields, football fields, parks, etc.;
8) Drainage of roof gardens and flower terraces;
9) Construction drainage of building foundation works;
10) Agricultural and horticultural underground irrigation and drainage systems;
11) Drainage system for low-lying wet land. Drainage of land preparation project Plastic blind ditch material is internationally known as Geocomposite dreinage systems (GDS), also known as three-dimensional drainage board, collection and drainage culvert material for civil engineering, etc. It is a three-dimensional three-dimensional porous material formed by heating and melting thermoplastic synthetic resin, extruding filaments through a nozzle and stacking them together, and sintering their joints.

Construction process of geotextile
1. The old pavement should be cleaned of dust, loose particles and sundries, and the surface should be kept dry. The sharp and abrupt parts of the road surface shall be leveled; for the seriously damaged and broken parts of the road surface, the broken parts shall be removed and repaired with asphalt concrete. For the pavement with serious cracks or ruts, a layer of 1-2cm leveling layer should be filled.

Precautions for construction of geogrid
The paving surface of the geogrid should be relatively flat. After the paving layer has passed the acceptance, in order to prevent the longitudinal skew phenomenon, first draw a white line or hanging line on the paving layer according to the width, and then start the paving, and then use iron Fix the end of the grille with nails (8 nails per meter width, fixed at an even distance), after fixing the end of the grille, use a paving machine to slowly pull the grille forward, and carry out manual labor for every 10 meters long. Tighten and straighten once until one roll of grille is finished, and then lay the next roll. The operation is the same as before. After laying one roll, use a 6T-10T road roller to roll it from the starting point to the forward direction.

The role of geogrid engineering
It has high strength, low creep, and can adapt to various environmental soils, which can fully meet the use of tall retaining walls in high-grade highways. It can effectively improve the interlocking and occlusal effect of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.

Product characteristics of flexible permeable pipes
1. The material of the soft permeable pipe 1) High carbon steel wire: phosphoric acid anti-rust treatment, PVC coating to prevent acid and alkali corrosion, unique steel wire spiral skeleton to ensure the smooth surface of the pipe wall and withstand pressure. 2) Non-woven filter layer: ensure effective filtration and prevent sediment from entering the tube. 3) Synthetic polyester fiber: The warp yarn is made of high-strength T-DOLON yarn or nylon yarn covered with PVC, and the weft yarn is made of special fiber, which has sufficient tensile strength.
