Abstract
The utility model relates to a main pipe for water supply, water discharge and pollution discharge for municipal construction engineering. Aiming to overcome defects in the prior art, the utility model provides a pipe with a wound hollow wall made of composite reinforced material, which has the advantages of easy installation and transportation, light weight per meter, strong pressure resistance, no need of enlarging producing equipment, and simple manufacturing process and can be used for water transportation and distribution engineering with definite pressure. The utility model comprises a pipe wall which is formed by the spiral winding of a double-layer pipe, wherein the inner layer of the double-layer pipe is a fiber reinforcing layer, and a gap between two adjacent parts of the double-layer pipe is filled with an adhesive layer. Because the pipe wall of the utility model is formed by the spiral winding of the double-layer pipe, the inner layer of which is a fiber reinforcing layer, the utility model has the advantages of easy processing and production, high productive speed, light weight per meter, and convenient installation and transportation and both the cost and the construction cost can be greatly reduced. Besides, because fiber reinforcing material has high mechanical strength, the pressure resistance of the wound pipe is obviously improved and the cost of the pipe is obviously reduced.
Description
Technical field
The utility model relates to a kind of urban engineering project plumbing, blowdown main pipe, specifically to a kind of improvement of existing plumbing, blow-off line, thereby can be used for having the transmission ﹠ distribution water conservancy project journey of certain pressure.
Background technique
Generally all adopt cement pipe as the trunk sewer pipeline on the urban engineering project now.The a large amount of reinforced concrete of this pipeline consumption, Mi Chongda, installation and transportation are all inconvenient, the difficult maintenance of easy to leak, and working life is short, in case run-down, both befouling environment, obstruction again.Also have a kind of double-wall corrugated pipe in addition, though it has overcome the defective of cement pipe,, if when producing diameter greater than 1.2 meters double-wall corrugated pipe, its investment in production equipment can be very big, and technology is very complicated, costs an arm and a leg, and is difficult to apply.
Summary of the invention
The utility model purpose is in order to overcome the shortcoming of prior art, and a kind of installation and transportation that provide are convenient, the rice heavy and light, resistance to pressure is strong and need not to enlarge the wrap style hollow wall combined type reinforcing material pipe that manufacturing mechanism, technology simply can be used for having the transmission ﹠ distribution water conservancy project journey of certain pressure.
To achieve these goals, the utility model has adopted following technological scheme.
Wrap style hollow wall combined type reinforcing material pipe of the present utility model comprises tube wall, and described tube wall is entwined by the bimetallic tube spiral, and the internal layer of bimetallic tube is a fiber-reinforced layer, and the place, slit of adjacent double-layers pipe is filled with adhesives layer.
The cross section of described bimetallic tube is a rectangular.
The cross section of described bimetallic tube is a square.
The utlity model has following advantage and good effect: because tube wall of the present utility model is that the bimetallic tube spiral of fiber-reinforced layer is entwined by internal layer, therefore processing and fabricating is simple, and speed of production is fast, and single Mi Chongliang is lighter, installation and transportation are convenient, and cost and operating expenses all can significantly reduce; And because the mechanical strength of fiber reinforcing material is very high, the resistance to pressure of therefore twining the pipeline of back formation significantly improves, and the pipeline cost significantly reduces.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1～Fig. 3, wrap style hollow wall combined type reinforcing material pipe 6 of the present utility model comprises tube wall, described tube wall is entwined by rectangular bimetallic tube 1 spiral, the tube wall internal layer of bimetallic tube 1 is a fiber-reinforced layer 4, skin is high density polyethylene (HDPE) top layer 5, the place, slit of adjacent rectangular bimetallic tube 1 is filled with adhesives layer 2, and fiber-reinforced layer 4, outer field polyethylene skin 5 and the bimetallic tube tube chamber 3 of adhesives layer 2 and bimetallic tube internal layer have formed the tube wall of reinforced pipe 6 jointly.When making, this kind wrap style hollow wall combined type reinforcing material pipe forms rectangular bimetallic tube 1 with the two extruders co-extrusion earlier, wherein extrude the high density polyethylene (HDPE) material for one, another extrudes the compound material of high density polyethylene (HDPE) and fiber, moulding in composite machine head, rectangular bimetallic tube after the moulding through vacuum cooling typing back and with its side by side by melting adhesives layer 2 spiral winding on forming roll that rubber extruding machine is extruded, thereby mutual bonding formation wrap style hollow wall composite material reinforced pipe 6 is deviate from reinforced pipe 6 again from forming roll.In addition, referring to Fig. 4, the also available square bimetallic tube spiral of the compound reinforced pipe 6 of wrap style of the present utility model is entwined.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
Claims (3)
1, a kind of wrap style hollow wall combined type reinforcing material pipe, it comprises tube wall, it is characterized in that: described tube wall is entwined by the bimetallic tube spiral, and the internal layer of bimetallic tube is a fiber-reinforced layer, and the place, slit of adjacent double-layers pipe is filled with adhesives layer.
2, wrap style hollow wall combined type reinforcing material pipe according to claim 1, it is characterized in that: the cross section of described bimetallic tube is a rectangular.
