By the punching block instillation process cement stone sand slurry is poured in the glass fibre reinforced plastics cylinder body outer wall and forms the concrete structure layer, its structure characteristics is: concrete and glass fibre reinforced plastic structure layer outer wall particle transition layer form the junction surface of combining closely, concrete in addition aquation is shunk, and makes concrete and glass fibre reinforced plastic structure layer form tight composite structure.The concrete pipe construction layer mainly provides the rigidity and the axial compression strength of pipeline.
The outer wall of concrete pipe structure twines reinforcement wire; and mainly hold interior laminated structure as pipeline; reinforcement wire is closely wrapped up by outer protective material, and external protective material can adopt glass fibre reinforced plastic material, thermoplastic material or resin mortar, is used for preventing the corrosion of steel wire burn into.
The utility model had both been avoided the shortcoming of traditional concrete ceiling coil, prestress steel cylinder concrete push pipe and glass fibre reinforced plastics push pipe, combined the advantage of traditional push pipe tubing again, mainly had the following advantages:
1, combines the intensity of reinforcement wire and glass fibre reinforced plastics, have very high hoop tensile strength, can bear the interior pressure of pressing very much;
2, make full use of the high rigidity of concrete, incompressible characteristics, can bear high external pressure and axial top power;
3, give full play to the ganoid characteristics of frp lining, have good hydraulic performance;
4, smooth outer surface is smooth does not absorb water, and can effectively reduce surface friction drag, and the required top of jacking power is little;
4, the corrosion resistant characteristics of anti-leakage that have glass fibre reinforced plastics, long service life.
5, joint is simple, easy to connect, safe and reliable, can be widely used in the construction of non-pressure push pipe and Pressure pipe.
Push pipe of the present utility model has corrosion resistance, the good hydraulic of glass fibre reinforced plastics, simultaneously also has the high rigidity of concrete pipe and the characteristics such as high strength of steel pipe, and its fabricating cost top power lower, that can bear is big and self required top power is less.
The beneficial effects of the utility model are: the little characteristics of big, the required top of top power power that push pipe of the present utility model has the rigidity height, intensity is good, corrosion-resistant, hydraulic performance is good (barrier performance is good), cost is low, can bear.
