Geocomposite Dreinage Systems(GDS)

Geocomposite dreinage systems(GDS)

Plastic blind ditch is known internationally as Geocomposite dreinage systems (GDS), also known as three-dimensional drainage board, drainage culvert material for civil engineering, etc. The plastic blind ditch is extruded by high-pressure polyethylene. It has different ribs and grooves on both sides to meet the needs of drainage, water stop and fixation. Compared with other soft plastic plates, it has a certain rigidity and is beneficial to maintaining the drainage cavity. The proportion of material is small, the cost is relatively low, it has the characteristics of cold resistance, corrosion resistance, bacteriostatic corrosion, buried in the tunnel lining, not easy to age, and long service life. The plastic blind ditch is composed of a plastic core body wrapped with filter cloth. The plastic core is made of thermoplastic synthetic resin as the main raw material. After modification, in the hot melt state, thin plastic filaments are extruded through the nozzle, and then the extruded plastic filaments are welded at the nodes through the forming device. , Forming a three-dimensional three-dimensional network structure. The plastic core has a variety of structural forms such as rectangle, hollow matrix, circular hollow circle and so on. The material overcomes the shortcomings of traditional blind ditch, has high surface opening rate, good water collection, large porosity, good drainage, strong pressure resistance, good pressure resistance, good flexibility, adapt to soil deformation, and good durability , Light weight, convenient construction, greatly reduced labor intensity of workers, and high construction efficiency. Therefore, it is generally welcomed by the Engineering Bureau and is widely used.

There are many kinds of products, such as round and rectangular sections, and there are several product specifications. According to customer orders, products with different characteristics such as high temperature resistance, flame retardant, strong acid and alkali resistance, high elasticity, and high hardness can be produced with different formulations.

FEATURE

1. The constituent fibers of the plastic blind ditch are filaments of about 2mm, which are fused and formed at the mutual joints to form a three-dimensional mesh body. The principle is the same as that of the truss of steel structure. The surface opening is 95-97 percent , which is more than 5 times that of the porous tube and 3-4 times that of the resin mesh tube. The surface water absorption rate is extremely high.

2. Because it is a three-dimensional structure, the porosity is 80-95 percent , the space and management are the same and it is light, and the compressive performance is more than 10 times stronger than the resin of the pipe structure. Therefore, even if it is compressed due to overload, it is a three-dimensional Because of the structure, the residual voids are also more than 50 percent , there is no problem of no water flow, and there is no need to consider that it will be crushed by earth pressure.

3. High compressive strength, its compression rate is lower than 10 percent under 250KPa pressure.

4. With anti-aging agent, it is durable, and it can be stable even if it is placed under water or soil for decades.

5. Compressive and flexible, it can also be used for curved roads and other curved positions. It is very light. If the backfill depth is about 10cm, it can also be backfilled with a bulldozer.

6. Due to the above characteristics, the various problems that have occurred in the traditional blind ditch in the past, such as uneven settlement or partial occlusion due to overload, and no gaps caused by crushing, can be solved by plastic blind ditch materials. .

7. Since it is formed by thermal melting and does not use adhesives, it will not cause collapse due to adhesive aging and peeling.
