Abstract

The utility model relates to a kind of HDPE double-wall corrugated pipe, comprise the bellows body be made up of outer polyethylene layers, steel band and inner layer polyethylene layer, described steel band is compounded in the inner side of described outer polyethylene layers, the two ends of described body are respectively public interface end and maternal interface end, clamping ring is provided with in described body maternal interface end, maternal interface end inside described clamping ring is also provided with METAL HEATING PROCESS ring, and described METAL HEATING PROCESS ring is drawn outside maternal interface end by wire; The outside of the public interface end of described body is provided with hot melt adhesive, and the public interface end inside described hot melt adhesive is provided with snap collar, and described hot melt adhesive is mated with described METAL HEATING PROCESS ring position.It is strong that the utility model has reliability, and interface is easy to leak not, and corrosion resistance is strong, the advantage that cohesiveencess is good and surface is not easy to crack.

Description

HDPE double-wall corrugated pipe
Technical field
The utility model relates to a kind of bellows, and a kind of HDPE double-wall corrugated pipe, belongs to tubing technical field specifically.
Background technique
Spigot and socket type HDPE double-wall corrugated pipe, as a kind of novel environmental protection tubing, by means of the performance that it is excellent, good application property, meets the construction requirement of Municipal Drainage Engineering.Along with domestic HDPE double-wall corrugated pipe production line is succeeded in developing, production technology level improves constantly, and construction technology is constantly ripe, and spigot and socket type HDPE double-wall corrugated pipe will have more vast potential for future development in drainage works.
At present, existing traditional easy seepage of double-wall corrugated interface tube, poor reliability, thus easily cause road surface to subside; And cementability is poor, anti-corrosion capability is weak, and external shock resistance ability is poor, and cementability is bad, and surface is easy to crack, and quality of product is difficult to ensure.
Model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of HDPE double-wall corrugated pipe, and have reliability strong, interface is easy to leak not, and corrosion resistance is strong, the advantage that cohesiveencess is good and surface is not easy to crack.
In order to solve above technical problem, the utility model provides a kind of HDPE double-wall corrugated pipe, comprise the bellows body be made up of outer polyethylene layers, steel band and inner layer polyethylene layer, described steel band is compounded in the inner side of described outer polyethylene layers, the two ends of described body are respectively public interface end and maternal interface end, be provided with clamping ring in described body maternal interface end, the maternal interface end inside described clamping ring is also provided with METAL HEATING PROCESS ring, described METAL HEATING PROCESS ring is drawn outside maternal interface end by wire; The outside of the public interface end of described body is provided with hot melt adhesive, and the public interface end inside described hot melt adhesive is provided with snap collar, and described hot melt adhesive is mated with described METAL HEATING PROCESS ring position.
The technological scheme that the utility model limits further is: aforesaid HDPE double-wall corrugated pipe, and the bellows-shaped of described steel band is consistent with the outer bellows-shaped of described body.
Aforesaid HDPE double-wall corrugated pipe, is at least embedded with two METAL HEATING PROCESS rings in described body maternal interface end.
Further, aforesaid HDPE double-wall corrugated pipe, described steel strip surface is by adhering resin hot melt adhesive and described outer polyethylene layers compound.
The beneficial effects of the utility model are:
Steel band of the present utility model is Galvanized Steel Strip, and steel strip surface is by adhering resin hot melt adhesive and described outer polyethylene layers compound, and can strengthen internal layer and corrosion resistance that is outer and that strengthen between steel band, the stress reducing steel band is concentrated; Due at the pre-buried electric heating wire of jointing, capacitance technology can be adopted to connect when therefore connecting, rapid and convenient, save manpower and facility, and quality of connection be high, can accomplish 100% No leakage.It is strong that the utility model has reliability, and interface is easy to leak not, and corrosion resistance is strong, the advantage that cohesiveencess is good and surface is not easy to crack.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
embodiment 1
A kind of HDPE double-wall corrugated pipe that the present embodiment provides, structure as shown in Figure 1, comprise the bellows body be made up of outer polyethylene layers 1, steel band 2 and inner layer polyethylene layer 3, steel band is compounded in the inner side of outer polyethylene layers, and the bellows-shaped of steel band is consistent with the outer bellows-shaped of body; The two ends of body are respectively public interface end 4 and maternal interface end 5, are provided with clamping ring 6 in body maternal interface end, the maternal interface end inside clamping ring 6 are also provided with two METAL HEATING PROCESS rings 7, and METAL HEATING PROCESS ring 7 is drawn outside maternal interface end by wire; The outside of the public interface end of body is provided with hot melt adhesive 8, and the public interface end inside hot melt adhesive is provided with snap collar 9, and hot melt adhesive is mated with METAL HEATING PROCESS ring position.
The present embodiment when mounted, the public interface end of bellows is inserted in the maternal interface end of next root bellows, now the clamping ring of interface and snap collar connect and fix, METAL HEATING PROCESS ring on maternal interface end is coated in the hot melt adhesive of public interface end, be connected with METAL HEATING PROCESS ring by the wire of drawing, direct heating of metal heating ring makes hotmelt melts, to reach the object of sealing two bellowss, greatly can reduce the timeliness of bellows when connecting like this, improve the installation efficiency of bellows, simultaneously owing to being provided with the intensity that METAL HEATING PROCESS ring can improve interface on body interface, to ensure the service life of body.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
