Abstract
The utility model relates to a plastic drainage pipe with a gradual-contraction type bearing interface, which relates to a drainage pipeline. The utility model mainly solves the problems of non-tight connection and sealing and inconvenient construction of the existing plastic drainage pipe, of which the pipe body intensity can not satisfy requirements for some use occasions. The utility model comprises a pipe body of which both ends are separately provided with an inserted interface and a bearing interface, spirally annular reinforcing ribs arranged on the outer surface of the pipe body and a sealing ring installed on the outer surface of the inserted interface. The utility model is characterized in that inner ring ribs and outer ring ribs are convexly arranged on the outer surface of the inserted interface, and the inner surface of the bearing interface is provided with a horn-shaped opening which can form gradual-contraction type cooperation with the inserted interface. The utility model can ensure tight connection and sealing among pipes and has the advantage of convenient construction, and a keel thickening wall structure of the utility model can strengthen the intensity of the pipe body.
Description
Technical field
The utility model relates to drainage pipe, the gutter that specifically a kind of urban construction is used.
Background technology
The gutter that present urban municipal construction is used mainly contains two classes, and a class is the reinforced concrete pipe that tradition is used, and another kind of is the plastic pipe that developed recently gets up.Plastic pipe is promoted the use of gradually because of it has in light weight, corrosion-resistant, advantages such as friction factor is low, easy construction.But it still has the following disadvantages, 1, because interface and birdsmouth are to adopt the dead-beat structure to peg graft, and it is tight to make that connection between the tube and tube seals inadequately, and is inconvenient to construct; 2, the enhancing mode of body is more single, and its intensity can not satisfy the desired bigger pressure of some use occasion, the impact force during as backfill.
Summary of the invention
The purpose of this utility model provides and a kind of the connection seals gradually compact form birdsmouth plastic drain-pipe tight, easy construction.
The utility model is achieved in that and comprises that two ends are respectively the body of interface and birdsmouth, are arranged on the spiral surrounding shape strength bar of outer surface of tube body and are installed in the sealing ring of interface external surface, ring muscle and outer shroud muscle in the external surface of said interface has risen, the inner surface of birdsmouth is for forming tubaeform uncovered that compact form gradually is sealed and matched with interface.
The keel thickened wall of impact force when above-mentioned body can bear backfill vertically in addition.
In being arranged on, said sealing ring encircles between muscle and the outer shroud muscle.
Interface of the present utility model adopts gradually with birdsmouth, and the compact form sealing structure cooperates, can guarantee that the connection sealing between the tube and tube is tight, and easy construction, its keel thickened wall structure can strengthen the intensity of body, guarantee that body can bear bigger pressure, especially the impact force during backfill, ring muscle and outer shroud muscle fix sealing ring in the external surface of interface has risen, can overcome traditional external surface that passes through at interface and have groove and fix the pipe thickness attenuate that sealing ring makes interface, the deficiency that the pressure that causes bearing reduces.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is interface and birdsmouth connection diagram.
---interface, 2--birdsmouth, 3---body, 4---spiral surrounding shape strength bar, 5---sealing ring, 6---interior ring muscle, 7---outer shroud muscle, 8---tubaeform uncovered, 9---keel thickened wall among the figure: 1.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: body 3 adopts the modified plastics mold pressing to make, referring to Fig. 1, its right left two ends are respectively interface 1 and birdsmouth 2, its external surface has spiral surrounding shape strength bar 4, keel thickened wall 9 is arranged vertically, and (thickness and the width of keel thickening muscle 9 can be determined according to requirement of strength, thickness is usually 5---20mm, width are usually 20---300mm), wherein, ring muscle 6 and outer shroud muscle 7 in the external surface of interface 1 has risen, in sealing ring 5 is arranged between ring muscle 6 and the outer shroud muscle 7, the inner surface of birdsmouth 2 is tubaeform uncovered 8 promptly to become the utility model.
When more piece body 3 interconnects, will have one of keel thickened wall 9 to face up, interface 1 inserts in the corresponding birdsmouth 2 and gets final product, and its interface coincide good, and seam crossing is smoothly tight, and easy construction.
Claims (3)
1, a kind of gradually compact form birdsmouth plastic drain-pipe, comprise that two ends are respectively the body of interface and birdsmouth, are arranged on the spiral surrounding shape strength bar of outer surface of tube body and are installed in the sealing ring of interface external surface, ring muscle and outer shroud muscle in the external surface that it is characterized in that said interface has risen, the inner surface of birdsmouth is for forming tubaeform uncovered that compact form gradually is sealed and matched with interface.
2,, it is characterized in that the keel thickened wall of impact force when said body can bear backfill vertically in addition by the described a kind of gradually compact form birdsmouth plastic drain-pipe of claim 1.
3,, it is characterized in that said sealing ring encircles between muscle and the outer shroud muscle in being arranged on by claim 1 or 2 described a kind of gradually compact form birdsmouth plastic drain-pipes.
