Description
Technical field
The present invention relates to double muscle inside and outside a kind of HDPE to strengthen sewage dedicated pipe, more particularly to a kind of buried winding bellows.Belong to pipe fitting technical field.
Background technology
Traditional sewage disposal drainage pipeline uses concrete duct, and this pipeline needs all to construct at the scene, and unusual inconvenience of constructing, construction cost is high, and can not be recycled, and service life is also subject to certain restrictions.
In recent years, with the wilderness demand to municipal pipeline, and it is some technological deficiencies before overcoming, many plastic conduits, such as PVC pipes, straight-through water-supply-pipe, reinforced steel-band helical bellows, the winding bellows with hollow fin occurs.HDPE helical bellowses are a kind of novel light tubing using high density polyethylene (HDPE) as raw material, there is in light weight, high pressure resistant, good toughness, fast, long lifespan of constructing, its excellent structural pipe wall design, compared with the tubing of other structures, cost substantially reduces, and due to easy to connect, reliable, at home and abroad it be used widely, largely replace pipe of concrete and cast iron pipe.
Because current HDPE helical bellowses are usually as the tubing for being embedded in subdrainage, it bears the size of external pressure, directly affects the quality of pipe performance, and its measurement index is ring stiffness.If the ring stiffness of HDPE helical bellowses is inadequate, it can cause tubing in construction or effect because being deformed can not bearing the pressure of outside.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided double muscle strengthen sewage dedicated pipe inside and outside a kind of HDPE, can strengthen the intensity and anti-pressure ability of winding bellows.
The object of the present invention is achieved like this：Double muscle strengthen sewage dedicated pipe inside and outside a kind of HDPE, it includes cylindrical inner tube, multiple supporting plates are evenly arranged with said inner tube circumferential direction inside direction, one end of the supporting plate is fixedly connected on tube wall, the other end, which crosses, to be connected in the geometric center of body, length direction helical ring of the outside wall surface of inner tube along the inner tube is wound with hollow outer tube, hollow cavity is formed between the crest and inner tube of outer tube, the trough of outer tube mutually fuses together with inner tube, muscle in enhancing is provided with the hollow cavity, one end of muscle is connected with the inwall of outer tube in enhancing, the other end is connected with the outer wall of inner tube, the outer muscle of enhancing is provided with the trough of the outer tube.
In the enhancing muscle can be it is single be vertically arranged, or two parallel verticals are set, or two form an angle and are arranged symmetrically.
The cross sectional shape of the outer muscle of the enhancing is semicircle or rectangle.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention sets the outer muscle of enhancing by muscle in being set in the hollow cavity of body, and in the most weak wave trough position of body, reaches dual booster action, so as to improve the intensity of sewage dedicated pipe and anti-pressure ability.

Embodiment
Referring to Fig. 1-Fig. 2, the present invention relates to double muscle inside and outside a kind of HDPE to strengthen sewage dedicated pipe, including cylindrical inner tube 1, multiple supporting plates 6 are evenly arranged with the circumferential direction inside direction of said inner tube 1, one end of the supporting plate 6 is fixedly connected on tube wall, and the other end, which crosses, to be connected in the geometric center of body 1, increases body allowable stress, pipe thickness can accordingly reduce, and cross the increase of water section；Length direction helical ring of the outside wall surface of inner tube 1 along the inner tube is wound with hollow outer tube 2,Hollow cavity 3 is formed between the crest and inner tube 1 of outer tube 2,The trough of outer tube 2 mutually fuses together with inner tube 1,Muscle 4 in enhancing is provided with the hollow cavity 3,One end of muscle 4 is connected with the inwall of outer tube 2 in enhancing,The other end is connected with the outer wall of inner tube 1,Muscle 4 can make single be vertically arranged in the enhancing,Or two parallel verticals are set,Or two form an angle and be arranged symmetrically,The outer muscle 5 of enhancing is provided with the trough of the outer tube 2,The cross sectional shape of the outer muscle 5 of the enhancing is semicircle or rectangle,Because wave trough position is weaker relative to other positions,Easily the normal use of pipe is influenceed because external force effect is damaged,The intensity and compression capability of body can be greatly improved by strengthening outer muscle 5 in wave trough position setting.
