Abstract
The utility model relates to a composite pipe which comprises an inner-layered pipe body and an outer-layered pipe body. The composite pipe is characterized in that a metal framework is arranged between the inner-layered pipe body and the outer-layered pipe body in a winding manner, a plurality of T-head hooks are arranged on the metal framework, the T-head hooks are composed of hook rods and barbs, each hook rod is connected with the barbs at two ends, one ends of the T-head hooks are connected to the inner-layered pipe body, and the other ends of the T-head hooks are connected to the outer-layered pipe body. The composite pipe has the advantages of high strength and capability of preventing the outer-layered pipe from delaminating from aging.
Description
Technical field
The utility model relates to building field draining tubing, and particularly a kind of heavy caliber is for the composite pipe of groundwater abstraction.
Background technique
Present stage, Real estate industry was very flourishing, needs to use heavy caliber water pipe and carry out draining in real estate development process, especially, in the process of digging ground, underground water need to be drained to rear construction.In south, because level of ground water is higher, foundation dredging just need to use heavy caliber water pipe to carry out draining later.At present, conventional waste pipe mainly divides two kinds, and one is polytene corrugated tube, and this tubing anti-pressure ability is not strong, the easy pressurized breakage in building site, and also not wear-resisting; Another kind is traditional rubber corrugated pipe, it is good that this tubing has anti-pressure ability, the advantage such as wear-resisting, but because it is that multilayer rubber is composited, between each layer, fit by the characteristic of adhesive and rubber self, easily layering, particularly outer layer rubber aging lax after, between internal layer and skin, add again metal layer, easier delamination.
Summary of the invention
The technical problems to be solved in the utility model is, the composite pipe that a kind of intensity is high, can prevent delamination after ageing of rubber is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of composite pipe, comprise internal layer body and outer body, it is characterized in that: between internal layer body and outer body, be also provided with metal frame, described metal frame is wrapped between internal layer body and outer body, metal frame is provided with some cross head coupler bodies, described cross head coupler body is made up of coupler body bar and hangnail, hangnail is connected to coupler body bar two ends, cross head coupler body one end connects internal layer body, and the other end connects outer body.
The hangnail of described cross head coupler body is vertical with coupler body bar, and the middle part of coupler body bar is fixedly connected with metal frame.
The hangnail of described cross head coupler body and coupler body bar are 60 degree angles, and the middle part of coupler body bar is fixedly connected with metal frame.
The middle part of described coupler body bar and metal frame welding.
Described interior tube body and outer tube body all adopt has flexible quality of rubber materials, can extruding and moulding.
The utility model arranges metal frame between internal layer body and outer tube body, can improve the intensity of composite pipe, makes composite pipe be not easy to be damaged by pressure by the vehicle on building site.Some cross head coupler bodies are set on metal frame, coupler body bar middle part is connected with metal frame by the mode of welding, the two ends of coupler body bar are equipped with hangnail, hangnail is imbedded respectively internal layer body and outer body in sebific duct forming process, can firmly internal layer body be connected with outer body like this, even if outer body becomes lax because of aging, also can not depart from metal frame and internal layer body, effectively overcome the technical problem of the aging rear easy delamination of composite pipe.
The hangnail at coupler body bar two ends, can be vertical with coupler body bar, also can be 60 degree angles with coupler body bar, all can play and prevent the lax rear easy technical problem departing from metal frame and internal layer body of outer hose aging.
In sum, the utlity model has the beneficial effect that intensity is high, can prevent the aging rear delamination of outer body.
