Description

A kind of sewage conduct

Technical field

The utility model is related to a kind of sewage anti-leakage structure, more particularly to a kind of sewage conduct.

Background technology

There is many ground sewage conduct in afternoon in urban road, since the distance of sewage transport is longer, the multiple pipes of generally use The connected form in road carries out guiding conveying, and connecting portion is weak link, easy tos produce leakage.

Pipeline in the prior art is often made of PE materials, is consolidated using fasteners such as anchor ears between two neighboring pipeline It is fixed, and it is provided with sealing ring on the connecting end surface of pipeline.However, the pipeline is in the long-term use, sealing ring is easily rotten Erosion, and then lead to sealing ring there are notches so that the sealing effect between pipeline reduces, and causes the sewage in pipeline to generate and lets out Dew.

Utility model content

The purpose of this utility model is to provide a kind of sewage conduct, and pipeline junction has good sealing performance.

The above-mentioned technical purpose of the utility model technical scheme is that：

A kind of sewage conduct, including be wholely set the first linkage section, the second linkage section and be connected to the first linkage section And the second third linkage section between linkage section, the first linkage section of one of sewage conduct can be set in another sewage pipe The outside of second linkage section in road, is provided with heating wire and groove on the inner wall of the first linkage section, and the both ends of heating wire are to extension It stretches on the outside of the first linkage section, filling member is fusible after heating is connected in groove.

Using the above scheme, when connecting sewage conduct, the second linkage section of a sewage conduct is inserted into another sewage pipe In first linkage section in road, a part for heating wire is sandwiched between the first linkage section and the second linkage section, to stretching out in first Heating wire on the outside of linkage section is powered, the inner wall of the first linkage section that electrothermal wire heating is bonded it, the second linkage section Outer wall and filling member are heated, and the inner wall fusing of the inner wall and the second linkage section of the first linkage section after heating is glued and melted Unencapsulated gap is filled between the first linkage section of filling member pair melted and the second linkage section, and the close of pipeline is realized with this Envelope, relative to the setting of anchor ear and sealing ring, increases the sealing performance of pipeline, prevents the leakage of sewage, extend pipeline Usage time.

Further preferably：The heating wire is along the inner wall circumferential direction winding of first linkage section, and entirety is annularly.

Using the above scheme, the heating wire of circumferential winding makes heating wire circumferential to the first linkage section and the second linkage section Heating is more uniform, and then increases the sealing effect between the first linkage section and the second linkage section.

Further preferably：The heating wire is in the wave with wave crest and trough along the axial direction of first linkage section Shape.

Using the above scheme, heating wire increases the width of heating wire axial direction along the first linkage section undulate, increases The heated perimeter of heating wire, and then increase the bonding range between the first linkage section and the second linkage section, strengthen so that The sealing effect and bonding strength of the two.

Further preferably：The groove is the annulus that section is in discount vibram outlet shape, and the filling member is the rounded circle in section Ring, when filling member is clamped with groove, a part for filling member protrudes from the opening of groove.

Further preferably：The groove is in segment shape, and groove is uniformly arranged along the circumferential direction of first linkage section Have multiple, the filling member is spherical, and when filling member is clamped with groove, a part for filling member protrudes from the opening of groove.

Using the above scheme, when groove and filling member circular or be circumferentially uniformly arranged enable filling member to melt uniformly Be filled, increase the sealing effect between the first linkage section and the second linkage section；The rounded filling member in section is convenient for First linkage section and the quick of the second linkage section install.

Further preferably：Restraining position ring block is arranged in the junction of first linkage section and third linkage section.

Using the above scheme, restriction effect from the second linkage section of spacing ring pair is when being threaded onto the first linkage section prevents the Two linkage sections are inserted into waste that is excessive and causing resource.

Further preferably：The side of the spacing ring towards the third linkage section is provided with guide surface.

Using the above scheme, guide surface is convenient for the conveying of sewage in the duct, reduces barrier effect of the spacing ring to sewage.

Further preferably：The spacing ring is towards the bulge loop that is provided with of first linkage section side, bulge loop and first The inner wall of linkage section forms a limiting slot, the first linkage section of one of sewage conduct and the second of another sewage conduct When linkage section connects, the end of the second linkage section is connected in limiting slot.

Using the above scheme, the second linkage section is connected in limiting slot, is extended effluent seepage and is needed the path passed through, increases Add the sealing effect of pipeline, also improves the structural stability after the first linkage section is connect with the second linkage section in addition.

Further preferably：The peripheral surface protrusion of the third linkage section has loop coil, and loop coil is along third linkage section Axis direction winding is molded.

Using the above scheme, loop coil increases the structural strength of third linkage section, has spy simple in structure, easy to process Point.

Further preferably：The loop coil is the hollow pipe of inner hollow.

Using the above scheme, hollow pipe reduce pipeline manufacture material, reduce production cost, relative to solid torus its Quality is smaller, also reduces transportation cost, is convenient for constructing operation.

In conclusion the utility model has the advantages that：

By the setting of heating wire, groove and filling member, spacing ring and loop coil, increase close when sewage conduct connects Sealing property prevents the leakage of sewage, extends the usage time of pipeline, has good structural strength.
