How to separate the primary and secondary pipes of the concrete drainage pipe
The primary and secondary pipes are distinguished according to the pressure that the pipeline can accept.
The primary and secondary pipes are determined by different depths of soil cover.
The difference lies in the diameter of the inner reinforcement and the concrete designation.
The drainage pipe mainly assumes the mission of drainage of rainwater, sewage, and irrigation and drainage of farmland. Drain pipes are divided into concrete pipes (CP) and reinforced concrete pipes (RCP).
The drain pipe standard has a pipe inner diameter DO (100mm-3000mm), a length LO (1m-20m) pressure index, class Ⅰ class Ⅱ class III caliber is divided into: flat port, enterprise port, socket socket, double socket, steel socket.
Production of reinforced concrete drainage pipe equipment: mixing system, pipe mold (flat mouth, groove, socket, double socket, steel socket), molding equipment (centrifuge, suspension roller, vertical axial kneading molding machine, vertical Radial kneading forming machine, core mold oscillating hydraulic forming machine, vertical radial kneading forming machine, core mold oscillating hydraulic forming machine, oscillating forming device), feeder, steel plate skeleton welding machine, hydraulic press, external pressure Machine and so on.
The drainage pipe is a new type of corrugated drainage plastic pipe made of high-density polyethylene (HDPE) and other additives. The permeable corrugated pipe is punched in the groove, and the outer circumference of the pipe is covered with needle-punched geotextiles. Processed. According to the type of bellows, it can be divided into single-wall permeable bellows and double-wall permeable bellows. As the tube hole in the product is in the trough and has a long shape, it effectively overcomes the disadvantages of the flat round hole product that is easily blocked and affects the drainage effect. According to different drainage requirements, the size of the tube hole can be 10mm × 1mm-30mm × 3mm, and can be evenly distributed in the range of 360 degrees, 270 degrees, 180 degrees, 90 degrees, etc., widely used in highways, railway subgrades, subway projects, waste landfills, tunnels, green belts, sports fields and water content Drainage categories such as high slope protection, and underground irrigation and drainage systems for agriculture and horticulture. It, together with soft permeable pipes and plastic blind ditches, have become the three major products in civil engineering construction (water seepage and drainage) in China. Depending on the size of the drainage pressure, the municipal drainage pipe network can use dual-arm bellows and straight wall pipes. Straight wall pipe has strong pressure acceptance ability, and can be used for special pipes of large-scale drainage and sewage pipe network.
