Plastic buried pipes have been widely used abroad because of the advantages of buried pipes, such as cast iron pipes, steel pipes, cement pipes and other traditional buried pipes:
Strength and rigidity
On the surface of plastics pipe strength and rigidity than the cement pipe, especially reinforced concrete pipe, plastic pipe is actually "flexible", in the correct design and construction situation of plastics pipe and the surrounding soil to bear the load, therefore, plastics pipe need not reach the same "rigid pipe and concrete pipe the strength and rigidity, can meet the requirements of using the mechanical properties of the buried.
The hydraulic characteristics of plastic pipe wall smooth, small resistance, water flux, water flow in the same caliber plastic pipe larger than concrete, terrain slope, plastic pipe diameter can be reduced, the smaller amount of construction.
Sealing cement pipe sealing is poor, the domestic flat interface concrete pipe in connection with a circle on the concrete seal, the construction is difficult to ensure no leakage, and the concrete pipe rigid pipe, a slight movement (such as soil uneven settlement) can cause joint damage, in addition, cement pipe using vulcanized rubber ring sealed plastic pipe connection sealing elastic plastic body with heat, the service life of the former than the latter, and the plastic pipe connection and sealing a series of strict requirements, to ensure maximum leakage will not occur. The life of the cement pipe is only 15 years, and the service life of the plastic pipe is 50 years -100 years.
Domestic sewage, rainwater and other usually corrosive, and industrial sewage corrosion greater, using metal and cement buried drainage pipe, corrosion resistance than plastic pipe difference. Corrosion in some parts of the outdoor environment is very large, such as the Tianjin New District of Tanggu City, land reclamation, sewage pipe laying cement after 3 years can not find, are salt corrosion in seawater was dropped, but two re laying of plastic pipe.
