Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drain pipes, and particularly relates to a reinforced drain pipe. Background Art
[0002] Most of the existing drain pipes are made of plastic pipes or polyethylene pipes, and the overall strength of the drain pipes is not high enough. Once buried underground, after long-term use, the surface of the drain pipes will be indented or collapsed due to extrusion, affecting the normal use of the pipes. Content of the Utility Model
[0003] The purpose of the utility model is to solve at least one problem of the existing technology, and to provide a reinforced drain pipe.
[0004] To achieve the above purpose, the utility model provides a reinforced drain pipe, which includes an inner pipe and a reinforcing pipe. The reinforcing pipe includes an arc-shaped pipe and a protective layer. The protective layer is wrapped outside the arc-shaped pipe. The arc-shaped pipe is formed by connecting a plurality of arc-shaped steel rings and horizontal steel strips. One side of the horizontal steel strip on the reinforcing pipe is spirally wound outside the inner pipe and is integrally formed by thermoplastic molding. The edges of adjacent two arc-shaped steel rings and the edges of adjacent two horizontal steel strips are tightly connected by a buckling method.
[0005] Preferably, plugs and slots adapted to the plugs are respectively provided at both ends of the inner pipe.
[0006] Preferably, the two inner pipes are fixedly connected or hot-melt connected by head-to-tail insertion of the plugs and slots.
[0007] Preferably, a sealing ring is installed at the connection position of the plug and the slot.
[0008] Preferably, the inner pipe is a plastic pipe or a plastic tube.
[0009] Preferably, the protective layer is a plastic layer.
[0010] Preferably, a buckling part formed by inward bending is provided on the inner wall of one side of each arc-shaped steel ring and horizontal steel strip, and a clamping groove is formed by outward bending at the outer wall edge of the other side. The buckling parts and the clamping grooves at the edges of adjacent two arc-shaped steel rings and the edges of adjacent two horizontal steel strips correspond to each other and are buckled to achieve tight connection.
[0011] Advantages of the present utility model: By spirally winding the reinforcing pipe on the outer side of the inner pipe and integrally connecting them through thermoplastic molding, several continuous arc-shaped steel rings are provided inside the reinforcing pipe, which can improve the overall strength of the drainage pipe and is not easily deformed; the reinforcing pipe adopts a structure in which the outer side of the arc-shaped pipe is wrapped with a protective layer. The cross-section of the arc-shaped pipe is semi-circular. The straight end of the arc-shaped pipe (i.e., one end of the horizontal steel strip) is spirally wound on the inner side of the inner pipe, so that the contact area between the reinforcing pipe and the inner pipe is large and the connection is more firm. The semi-circular structure design can reduce the production cost of the reinforcing pipe; the adjacent two arc-shaped steel ring edges and the adjacent two horizontal steel strip edges in the arc-shaped pipe are tightly connected by a buckling method, so that the arc-shaped pipe can have a certain axial expansion space, and the protective layer can fully cover the adjacent two arc-shaped steel ring edges and the connection positions of the adjacent two horizontal steel strips, improving the protection effect.
