Drainage pipes mainly undertake the tasks of rainwater, sewage, farmland irrigation and drainage. Drainage pipes are divided into plastic drainage pipes, concrete pipes (CP) and reinforced concrete pipes (RCP).

Main applications

1. Vertical and horizontal drainage and water seepage of expressway;

2. Vertical and horizontal drainage on the back of various retaining walls and ditches of expressways;

3. Drainage of tunnels and underground passages;

4 municipal engineering, water purification plants, sewage plants, garbage dumps and other water supply and drainage;

5. Drainage of golf courses, sports fields and parks;

6. Soil and water conservation of hillside slope development:

7. Underground drainage of land consolidation project;

The specifications of the drainage pipe include the pipe inner diameter DO (100 mm-3000 mm), the length LO (1m-20m) and the pressure index. The first, second and third types of caliber are divided into: flat mouth, tongue groove, socket, double socket and steel socket.

Equipment for producing reinforced concrete drainage pipes: mixing system, pipe mould (flat mouth, tenon and groove, socket, double socket and steel socket), molding equipment (centrifuge, roller hanger, vertical axial extrusion molding machine, vertical radial extrusion molding machine, core mold vibration hydraulic molding machine, vertical radial extrusion molding machine, core mold vibration hydraulic molding machine and vibration molding device), feeder, steel plate frame roller welding machine, hydraulic press and external press.

Drainage pipe is a new type of plastic corrugated pipe, which is made of high density polyethylene (HDPE) and other additives. Permeable corrugated pipe is made by punching holes in the groove and wrapping needle-punched geotextile around the pipe.

According to the types of bellows, it can be divided into single-wall breathable bellows and double-wall breathable bellows. Because the pipe hole of the product is in the groove and long, it effectively overcomes the shortcoming that the flat round hole product is easy to block and affects the drainage effect. According to different drainage requirements, the pipe hole size can be10mm×1mm-30mm× 3mm, and it can be in the range of 360 degrees, 270 degrees, 180 degrees and 90 degrees. It is widely used in drainage fields such as highway, railway subgrade, subway engineering, landfill, tunnel, green belt, sports ground, slope protection caused by high water content, and underground irrigation and drainage systems such as agriculture and gardening. It, soft permeable pipe and plastic blind ditch have become the three main products in China's civil engineering construction (water seepage and drainage).
