Blind ditch, also known as hidden ditch, is a new type of geosynthetic material. The main function of plastic blind ditches is to collect and discharge water from the soil, reduce groundwater pressure, remove excess water, and protect the soil and buildings from damage caused by seepage deformation. Underground drainage channels can be used to drain groundwater and lower the groundwater level.

一、Characteristics of blind ditch

The plastic core of blind ditch is mainly made of thermoplastic synthetic resin as the main raw material. After modification, fine plastic wire strips are extruded through nozzles in a hot melt state, and then the extruded plastic wire is fused at the nodes through a molding device to form a three-dimensional network structure.

二、The main uses of plastic blind ditches

1. Road drainage: used for longitudinal and transverse drainage of roads, ensuring the safety and comfort of road traffic.

2. Bridge drainage: Used for the drainage system of bridges to prevent erosion of bridge structures by water flow.

3. Building drainage: Used for drainage of roofs, floors, walls, and other parts of buildings to prevent leakage and structural damage.

4. Tunnel drainage: used for drainage of the arch and bottom of the tunnel, ensuring dryness and safety inside the tunnel.

5. Airport drainage: Used for the drainage of airport runways to prevent water accumulation from affecting the safety of aircraft takeoff and landing.
三、The advantages of plastic blind ditches

1. Good compressive performance: Plastic blind ditches have high compressive strength and can withstand large loads.

2. Strong anti-aging performance: plastic blind ditch is not easy to age and has a long service life in outdoor environment.

3. Good corrosion resistance: Plastic blind ditches have good corrosion resistance and can resist the erosion of various chemicals.

4. Convenient construction: Plastic blind ditches are lightweight, easy to install, and have high construction efficiency.

5. Good environmental performance: Plastic blind ditches can be recycled and have no pollution to the environment.
