Abstract
The invention discloses a large-calibre double-wall corrugated water pipe. The pipe wall of the large-calibre double-wall corrugated water pipe is composed of an inner layer and an outer layer, wherein the inner pipe wall is smooth while the outer pipe wall is trapezoidal and corrugated; a steel hoop is arranged in a cavity between the inner wall and the outer wall; and a trapezoidal bottom groove is formed on the outer wall so that the outer wall is integrally connected with the inner wall. As the steel hoop is arranged in the cavity between the inner wall and the outer wall of the large-calibre double-wall corrugated water pipe, the strength of the water pipe is improved; and compared with the large-calibre steel-plastic drain pipe generally used in the prior art, the large-calibre double-wall corrugated water pipe has the advantages of low integrated weight and low manufacturing cost, mounting and use convenience and low production cost.
Description
Technical field:
The present invention relates to a kind of tubing, is large-caliber double-wall ripple water pipe specifically.
Background technique:
In the prior art, municipal drainage equipment is the plastic cement winding structure that gets up of the drainage pipe developed recently in city specifically, the steel plastic strip water pipe with the steel band reinforced plastics is fallen over each other to study in countries in the world, it is rolled by strip usually and forms, strip is made up of the cap portion of bottom, spine and crestal culmination portion, rolls in the process strip is made by helical coil, embeds steel band between spine, the height at steel band top and spine top is approximate, has cladded plastic cement at last on the waste pipe outer wall and has finished rolling of waste pipe.This type of steel plastic strip water wall pipe is in light weight, corrosion-resistant, frictional resistance is low, but its intensity is relatively poor, and complex structure uses inconvenience, be unfavorable for installing, and cost of production is higher.
Summary of the invention:
Be to solve the deficiencies in the prior art, the invention provides a kind of intensity height, cost is low, in light weight, easy to install and cost of production is low large-caliber double-wall ripple water pipe.
The present invention is achieved in that large-caliber double-wall ripple water pipe, the tube wall of described water pipe constitutes by the inside and outside is two-layer, its inner tubal wall is smooth, outer tube wall is trapezoidal corrugated, between the described inside and outside wall cavity is arranged, and connect as one at outer wall trapezoidal bottom groove and inwall, it is characterized in that: be provided with stirrup in the described cavity.
The material of described water pipe adopts PVC.
The tube wall of large-caliber double-wall ripple water pipe of the present invention constitutes by the inside and outside is two-layer, and its inner tubal wall is smooth, and outer tube wall is trapezoidal corrugated, is provided with stirrup in the cavity between the inside and outside wall, and connects as one at outer wall trapezoidal bottom groove and inwall.Owing to be provided with stirrup in the cavity between the large-caliber double-wall ripple water pipe inside and outside wall, improved the intensity of water pipe, compare owing to be not to roll by strip to form with the large-diameter steel-plastic waste pipe that generally uses in the prior art, saved metal consumption, have that overall weight is light, cost is low, easy to install and characteristics that cost of production is low.
Description of drawings:
Accompanying drawing 1 is the structural representation of the embodiment of the invention.
Label among Fig. 1 is: 1, water pipe; 2, inner tubal wall; 3, outer tube wall; 4, cavity; 5, stirrup.
Embodiment:
Below in conjunction with drawings and Examples, the present invention is described in further detail, but do not constitute any limitation of the invention:
Embodiment according to Fig. 1 as can be known, a kind of large-caliber double-wall ripple polyvinyl chloride pipe 1, its tube wall constitutes by the inside and outside is two-layer, its inner tubal wall 2 is smooth, outer tube wall 3 is trapezoidal corrugated, is provided with stirrup 5 in the cavity 4 between the inside and outside wall, and connects as one at outer wall trapezoidal bottom groove and inwall.
Embodiment is just for the ease of understanding technological scheme of the present invention; do not constitute limiting the scope of the invention; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present invention above scheme being done that does not break away from technical solution of the present invention all still belongs within the protection domain of the present invention.
