Description

Double-embedded spiral winding corrugated pipe

Technical Field

The utility model relates to a drainage pipe technical field especially relates to a two spiral winding bellows that inlay.

Background

The drainage pipeline refers to a system consisting of a pipeline for collecting and discharging sewage, wastewater and rainwater and auxiliary facilities thereof, and comprises a main pipe, branch pipes and pipelines leading to a treatment plant, and the pipelines which are built on a street or at any other place and have the function of drainage are taken as drainage pipeline statistics.

When the existing sectional material pipe belts are connected, the single-layer pipe belts are wound, laminated or extruded and connected in a tubular winding mode, such as a polyethylene plastic steel winding pipe and a hollow wall winding pipe, the connection safety is poor, and the connection part is easy to crack when being dragged by external force.

Therefore, we propose a double-embedded spiral-wound corrugated pipe to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the spiral winding junction easily cracks on the basis of the sectional material pipe belt in the prior art, and providing a double-embedded spiral winding corrugated pipe.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a two inlay spiral winding bellows, includes inner tube and outer tube, the outer tube cover is established outside the inner tube, the inner wall of inner tube is smooth setting, the outer wall of inner tube is provided with the ripple strip, be equipped with on the outer tube with ripple strip assorted card hole.

Preferably, the corrugated strip is spirally arranged and fixedly wound outside the inner pipe.

Preferably, a plurality of first reinforcing ribs are embedded in the corrugated strip.

Preferably, the inner tube section is unfolded and rotationally symmetrically arranged, the left side and the right side of the section of the inner tube are both provided with a tenon and a clamping groove, and the tenon is matched with the clamping groove.

Preferably, a plurality of second reinforcing ribs are filled in the inner tube.

Compared with the prior art, the beneficial effects of the utility model are that:

through setting up tenon tongue and draw-in groove, realize twining the locking with section bar pipe area through tenon tongue and draw-in groove interlocking in succession and connect, bond or weld together through the factor adhesive to this kind of mode carries out the requirement that spiral winding bellows satisfies the leakproofness, forms the pipeline that has high compressive strength simultaneously, and weight is lighter, connects fewly, easy operation.

The utility model discloses the leakproofness is better and weight is lighter, connects fewly, easy operation.
