Abstract

The utility model provides a polyethylene steel strip reinforced hollow winding structure wall pipe, which comprises a pipe wall formed by hollow winding. Hollow holes are uniformly formed on the cross section of the pipe wall; and flat steel strips are arranged among the hollow holes; polyethylene and flat steel strips are adopted as raw materials, and the polyethylene steel strip reinforced hollow winding structure wall pipe is manufactured through a plastics extrusion production line in coordination with a flat steel strip forming machine; long stripe-shaped flat steel strip is embedded in the hollow pipe wall, thereby utilizing the corrosion resistance of polyethylene as well as the rigidity of the flat steel strip, and meeting the requirement for anticorrosion of the pipe buried in the ground; the embedment of the flat steel strip improves the ring-stiffness of the pipe, so that the hollow holes which are uniformly formed on the cross section of the pipe wall reduces the usage of polyethylene, thereby greatly improving the cost performance of the pipe. The polyethylene steel strip reinforced hollow winding structure wall pipe can be used for non-pressure water drainage in cities, replace a cement pipe, etc. and can serve as a well wall pipe in the well digging field.

Description

The polyethylene steel band strengthens the hollow winding structure wall pipe
(1) technical field
The utility model relates to the drainage pipe technology, is specifically related to a kind of no pressure water pipe material.
(2) background technique
At present, the drainage pipe of China all adopts cement pipe or polythene material, cement pipe Heavy Weight, poor rigidity, and the rigidity of polythene material is also undesirable, and these problems all make the materials of tubing increase greatly, cost up, the life-span reduces.
(3) summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, both kept poly corrosion resistant performance, improved the ring stiffness of tubing again, the polyethylene steel band that has reduced the polyethylene consumption simultaneously strengthens the hollow winding structure wall pipe.
The purpose of this utility model is achieved in that it comprises the tube wall that hollow is Wrapping formed, evenly is provided with hollow hole on the wall cross-section, is provided with the band steel band between the hollow hole.
The utility model also has some technical characteristicss like this:
1, described hollow hole cross section is square;
2, described band steel band is strip, equidistantly and hollow hole arranged in a crossed manner.
It is raw material that the utility model adopts polyethylene and band steel band, through the plastics extrusion line, cooperates the flat steel strip molding machine and makes.The utility model is imbedded strip band steel band in the hollow tube wall, not only utilized poly corrosion resistant performance but also utilized the rigidity of band steel band, guaranteed the buried requirement for anticorrosion of tubing, again since the band steel band imbed the ring stiffness that has improved tubing, therefore on wall cross-section, evenly be provided with hollow hole, reduce poly consumption, increased substantially the cost performance of tubing.The utility model can be used as the no pressure water of municipal administration, and place of cement pipe etc. also can be applicable to the well-digging field, as borehole wall tubing.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is further described:
In conjunction with Fig. 1, present embodiment comprises the Wrapping formed tube wall of hollow 1, evenly is provided with hollow hole 2 on tube wall 1 cross section, and hollow hole 2 cross sections are square, are provided with band steel band 3 between the hollow hole 2, and band steel band 3 is strip, equidistantly and hollow hole arranged in a crossed manner.

Claims (3)

1, a kind of polyethylene steel band strengthens the hollow winding structure wall pipe, it is characterized in that it comprises the tube wall that hollow is Wrapping formed, evenly is provided with hollow hole on the wall cross-section, is provided with the band steel band between the hollow hole.
2, polyethylene steel band according to claim 1 strengthens the hollow winding structure wall pipe, it is characterized in that described hollow hole cross section is square.
3, polyethylene steel band according to claim 1 and 2 strengthens the hollow winding structure wall pipe, it is characterized in that described band steel band is strip, equidistantly and hollow hole arranged in a crossed manner.
