PRODUCT DETAILS

The plastic blind ditch is a filter cloth group wrapped by a plastic core. The plastic core body is a thermoplastic synthetic resin as the main raw material, after modification, in the hot melt state, through the nozzle to squeeze out the thin plastic wire, and then through the molding device to extrude the plastic wire on the node welding, forming a three-dimensional network structure. Plastic core has a rectangular, hollow matrix, circular hollow circular and other structural forms. The material overcomes the shortcomings of the traditional blind ditch, and has high surface opening rate, good water collection, large void ratio, good drainage, strong pressure resistance, good pressure resistance, good flexibility, adaptability to soil deformation, 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 widely used.

Scope of application

1) Reinforcement and drainage of road and railway roadbed shoulders;

2) Drainage of tunnels, underground passages and underground freight yards;

3) Water and soil conservation of hillside land and slope development;

4) Vertical and horizontal drainage of various retaining wall edges;

5) Drainage of slippery ground;

6) Drainage of ash pile in thermal power plant. Drainage of landfill works;

7) Drainage of rest green areas such as sports ground, golf course, baseball field, football field, park, etc;

8) Drainage of roof garden and flower table;

9) Construction drainage of building foundation works;

10) Underground irrigation and drainage system for agriculture and horticulture;

11) Drainage system for low-lying wet ground. The drainage plastic blind ditch material for soil preparation engineering is internationally called composite geotechnical drainage 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 porous material formed by heating and melting the thermoplastic synthetic resin through the nozzle to extrude the fiber filaments and stack them together, and melting the phase contacts.

Product Performance

This product is made of high-pressure polyethylene extrusion, with different ribs and grooves on both sides to meet the needs of drainage, water sealing and fixing. Compared with other soft plastic plates, it has a certain rigidity, which is beneficial to maintain the drainage cavity. The proportion of the material is small, the cost is relatively low, it has the characteristics of cold resistance, corrosion resistance, bacterial corrosion resistance, and not easy to age when buried in the tunnel lining, and long service life.

Product Features

1. The constituent fiber of the plastic blind groove is about 2mm wire strips, which are fused into a three-dimensional mesh body with the same principle as the truss principle of the steel structure. The surface opening is 95-97%, which is more than 5 times that of the perforated tube, 3-4 times that of the resin mesh tube, and the surface water absorption rate is extremely high.

2. As it is a three-dimensional structure, its void ratio is 80-95%, which forms the same space as management and is light, and its compressive performance is more than 10 times stronger than that of the resin of the pipe structure. Therefore, even if it is pressed due to overload, the residual void is more than 50% due to the three-dimensional structure, and there is no problem of water failure, and it is not necessary to consider being crushed by earth pressure.

3, the compressive strength, 250KPa pressure, the compression rate is less than 10%.

4, with anti-aging agent, durable, in the water, soil and other places placed for decades can also ensure stability.

5. Compressureproof and flexible. It can also be constructed for curved positions such as curves. It is very light. If the backfilling depth is about 10cm, bulldozers can also be used for backfilling.

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

7, due to the use of hot melt molding without the use of adhesives, it will not be due to the aging and peeling of the adhesive caused by collapse.
