Abstract
The invention discloses a novel HDPE corrugated pipe which comprises an inner layer pipe body and an outer layer corrugated pipe body. The inner layer pipe body and the outer layer corrugated pipe body are fixed in a fit mode. The outer layer corrugated pipe body is provided with corrugated spaces and corrugated gaps, wherein one corrugated gap is formed between every two corrugated spaces. A reinforcing support is arranged in each corrugated space and is in a triangular shape. According to the novel HDPE corrugated pipe, due to the fact that each iron block reinforcing support is arranged between every two corrugated spaces, the compression resistance of the corrugated pipe is improved, and the probability that the corrugated pipe is damaged due to road settlement is lowered.
Description
Technical field
The present invention relates to a kind of bellows, particularly relate to a kind of HDPE enhancement mode bellows.
Background technique
HDPE (High Density Polyethylene, high density polyethylene (HDPE)) double-wall corrugated pipe, be called for short PE bellows, take high density polyethylene (HDPE) as a kind of novel light tubing of raw material, inner wall smooth is smooth, outer wall is trapezoidal or arc corrugated rib, is the tubing of hollow between inner and outer wall ripple.Have that critical external compressive resistance ability is strong, engineering cost is low, the feature such as easy construction, low-temperature resistant and shock resistant performance, chemical stability are good, long service life, be widely used in industry and civil outdoor drainage system, belong to environment-friendly product.It has become the first-selected tubing of pipeline field " to mould Dai Gang ", which overcomes that the installation difficulty such as cement pipe, stoneware pipe, cast iron tube are large, easy-to-rust, resistance to water-flow are large, shortcoming that breed bacteria, life-span are short.
In actual use, HDPE bellows in the past has following problem:
(1) soil settlement can impact HDPE bellows, affects the anti-pressure ability of HDPE bellows, and the time can cause damage to HDPE bellows for a long time.
(2) inconvenience installed by existing HDPE bellows, and inside is not corrosion-resistant.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of HDPE bellows of new structure, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of anti-pressure ability high and with the bellows of antiseptic effect.
A kind of novel HDPE bellows, comprise inner tube and outer bellows, described inner tube and the laminating of outer bellows are fixed, outer bellows is divided into the ripple gap between ripple space and adjacent two ripple spaces, it is characterized in that: be provided with reinforcing bracket in described ripple space, described reinforcing bracket is a triangular supports.
Further, one end of described inner tube is provided with interior joint, and the other end is provided with outer joint, and described interior joint and outer joint are buckle and arrange, and two HDPE bellowss are equally fastened togather fixing by interior joint and outer joint.
Further, one deck anticorrosive coat is also provided with in described inner tube.
Further, described anticorrosive coat is epoxy powder.
Further, the material of described reinforcing bracket is iron block.
By such scheme, the present invention at least has the following advantages:
(1) be provided with iron block reinforcing bracket between adjacent corrugations in the present invention, add the compression resistance of bellows, reduce the possibility of the destruction bellows brought by road settlement.
(2) be provided with anticorrosive coat in the present invention, can better at the cable of pipe interior, prevent it from addling by protection setting.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Be structural representation of the present invention see Fig. 1, a kind of novel HDPE bellows, comprise inner tube 1 and outer bellows 2, described inner tube 1 and outer bellows 2 are fitted fixing, outer bellows 2 is divided into the ripple gap 4 between ripple space 3 and adjacent two ripple spaces 3, be provided with reinforcing bracket 5 in ripple space 3, described reinforcing bracket 5 is a triangular supports, and the material of reinforcing bracket 5 is iron block.
One end of inner tube 1 is provided with interior joint 6, and the other end is provided with outer joint 7, and described interior joint 6 and outer joint 7 are buckle and arrange, and two HDPE bellowss are equally fastened togather fixing by interior joint 6 and outer joint 7.Also be provided with one deck anticorrosive coat 8 in inner tube 1, anticorrosive coat 8 is epoxy powder.
The above is only the preferred embodiment of the present invention; be not limited to the present invention; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection scope of the present invention.
