Description
Technical Field
The utility model relates to the technical field of drainage pipelines, in particular to a novel reinforced concrete pipe lined with a high-density polyethylene plate.
Background
At present, the existing pipelines widely used in this technical field are mainly existing concrete and reinforced concrete drainage pipes manufactured according to the regulations in the concrete and reinforced concrete drainage pipes (GB/T11836-2009), which mainly have the following disadvantages:
(1) impact resistance and weak shearing force
The strength of the concrete and reinforced concrete drain pipes mainly comes from the concrete pipe wall and the reinforced concrete pipe wall provided with the reinforcing steel bar layer, and the concrete and reinforced concrete drain pipes belong to rigid pipelines.
(2) Rough pipe wall, high friction coefficient, easy generation of pipe siltation and influence on flow cross section
Because the inner wall of the concrete and reinforced concrete drain pipe cannot be smooth, the friction coefficient is increased. Because concrete and reinforced concrete drain pipe pipeline slope is less, and the coefficient of friction drag is great, easily produces the siltation in the pipeline, in case the sediment siltation is concreted after, influences the pipeline and overflows the section.
(3) Poor corrosion resistance
The corrosion resistance of concrete and reinforced concrete drainage pipes depends on the characteristics of concrete, generally has poor corrosion resistance, and particularly in industrial drainage and municipal drainage (rainwater and sewage) pipelines, because the sewage, the wastewater and the generated gas in the pipelines have corrosiveness, the pipeline structure is damaged after a long time, and the service life is shortened.
(4) Poor impermeability
The main material of the concrete and reinforced concrete drain pipe is concrete, if impervious concrete is not adopted, the general impermeability is poor, and the water body in the pipe and the groundwater cannot be effectively prevented from leaking.
(5) The joints between the pipe joints are easy to shift, slide and shrink and tear
The front and rear pipe joints of concrete and reinforced concrete drain pipes generally adopt flexible joints and rigid joints. The flexible interface of the pipeline is generally sealed by adopting fillers such as rubber rings, cotton and hemp and the like, hard sealing cannot be formed, and the leakage at the interface of the pipeline is easily caused by long-time aging of the rubber rings and contraction of the cotton and hemp; the rigid pipeline joint generally adopts a hard plugging mode, but the mode cannot effectively resist the tearing of the joint caused by pipeline sinking.
