Description
Technical field
The utility model relates to pipe technology field, particularly relates to a kind of steel plastic compount and strengthens spiral double wave pipe.
Background technique
Steel plastic compount strengthens the high rigidity of helical bellows integrated steel band and poly corrosion resistance, and frictional resistance is low, resistance to wears, and has very high ring stiffness, and integral forming technique is good, seam tensile strength and anti-corrosive properties high, the life-span is longer.Because composite strengthening steel band substantially increases the bulk strength of tubing, tubing is made to have better withstand voltage and impact strength and good geological adaptability, application area is more extensive, meet the application requirement of various geological condition and various engineering, be widely used in the fields such as expressway, urban construction, plumbing, airdrome, mine, be especially applicable to the large foundation construction project of length service life.
Chinese invention discloses patent No. CN103727325A steel band reinforced spiral ripple pipe, comprise inner tube, inner tube outer helical shape winding steel, in conjunction with external pipe outside steel band, the pitch dimension of described width of steel band and winding is less than prior art width of steel band and pitch dimension respectively; This invention adopts the pitch dimension changing width of steel band and winding, although rigidity and the overall performance of pipeline can be adjusted, but in actual production process, the pipeline of equal length needs to be wound around more multi-turn steel band, owing to not being connected between steel band circle with circle, this place often insufficient strength, impact resistance is poor, is easy to cause this place's fail in compression during construction.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and provide a kind of reasonable in design, structure is simple, ring stiffness and good impact resistance, and bearing capacity is strong, and the steel plastic compount of long service life strengthens spiral double wave pipe.
For achieving the above object, the utility model is by the following technical solutions:
A kind of steel plastic compount strengthens spiral double wave pipe, and it comprises inner tube, and described inner tube outer helical is wound with steel band, is compounded with external pipe outside described steel band, and described steel band cross section is dual waves structure.
Described inner tube and external pipe are polyethylene layer.The pipeline break elongation percentage adopting polythene material obtained is very high, extensibility is very strong, such as constructing, land subsidence or when there is earthquake, can produce deformation resistance and not rupture, can better with steel band phase compound.
Described thickness of strips is 0.4-0.6mm, and width of steel band is 170-220mm.Adopt wider steel band, improve the manufacturing efficiency of pipeline.
The utility model adopts above technological scheme, described steel band cross section is dual waves structure, this design greatly improves moment of inertia and the ring stiffness of pipeline, compared with conventional helical bellows, decrease the required number of turns be wound around of steel band on equal length pipeline, decrease weak part between steel band circle and circle, thus improve the shock resistance of pipeline, ring stiffness and mechanical strength, effectively avoid construction to cause pipeline fail in compression, pipe diameter can also be made to do more.The utility model is reasonable in design, and structure is simple, good impact resistance, and bearing capacity is strong, long service life.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is further elaborated:
Fig. 1 is that the utility model steel plastic compount strengthens spiral double wave tubular construction schematic diagram.
Embodiment
As shown in Figure 1, the utility model comprises inner tube 1, and described inner tube 1 outer helical is wound with steel band 2, is compounded with external pipe 3 outside described steel band 2, and described steel band 2 cross section is dual waves structure 21.
Described inner tube 1 and external pipe 3 are polyethylene layer.The pipeline break elongation percentage adopting polythene material obtained is very high, extensibility is very strong, such as constructing, land subsidence or when there is earthquake, can produce deformation resistance and not rupture, can better with steel band phase compound.
Described steel band 2 thickness is 0.4-0.6mm, and width of steel band is 170-220mm.Adopt wider steel band, improve the manufacturing efficiency of pipeline.
The utility model adopts above technological scheme, described steel band 2 cross section is dual waves structure 21, this design greatly improves moment of inertia and the ring stiffness of pipeline, compared with conventional helical bellows, decrease the required number of turns be wound around of steel band on equal length pipeline, decrease weak part between steel band circle and circle, thus improve the shock resistance of pipeline, ring stiffness and mechanical strength, effectively avoid construction to cause pipeline fail in compression, pipe diameter can also be made to do more.
More than describe and should not have any restriction to protection domain of the present utility model.
