Background technique
In recent years a major obstacle that runs in promoting the plastic underground waste pipe is: expense, Mi Chong (weight of every meter length) are big, price is more expensive than the tubing materials of the plastic underground waste pipe of major diameter (internal diameter is more than 800 millimeters), can cause the ring stiffness deficiency heavily again but reduce rice.According to practical experience, it is more acceptant to apply the plastic underground waste pipe below 800 millimeters at diameter, because though the tubing price is more expensive than concrete pipe, but owing to reasons such as convenient and quick construction, comprehensive cost is approaching, and plastic underground waste pipe good seal, corrosion-resistant etc. advantage are more remarkable.But the difference in selling prices of larger-diameter plastic underground waste pipe and concrete pipe is just increasing, even may differ from several times.Even operating expenses is lower, comprehensive cost is still high a lot.What therefore, actual at present use plastic underground waste pipe was more still is in the diameter small range.So larger-diameter plastic tube never can be extensive use of.So far the plastic underground waste pipe product that state's inner diameter is bigger mainly is an all-plastic winding structure pipe, only has enterprise of a few family can produce the above double-wall corrugated pipe of diameter 800mm, and maximum inner diameter is to 1200mm.Mainly contain two kinds of structures; A kind of is " the twining double-walled rectangular hollow rib wall pipe " that is commonly referred to ' Hollow wall tube ' or ' two flat walls pipe '.And a kind of steel-band reinforced steel plastic composite wound pipe has solved the application problem of major diameter waste pipe preferably, because shaped-steel strip is after twining, being combined into pipe with plastics, pipe ring rigidity is greatly increased, the big reduction of Mi Chongda simultaneously, under the prerequisite of same ring stiffness, the rice of shaped-steel strip coiled composite tube heavily have only overall plastic waste pipe rice heavy 40%, cost correspondingly reduces greatly.
The steel-band reinforced steel plastic composite wound pipe of having developed at present comprises by shaped-steel strip and twines the tube wall skeleton that forms that the inner and outer wall that forms composite winding pipe is twined by plastic tape respectively in the inside and outside surface of tube wall skeleton.Currently used shaped-steel strip mainly contains two kinds of structures: a kind of cross section of shaped-steel strip is " Ω " shape, this kind composite winding pipe is because outer wall has very dark spiral chute, the tractive resistance that is run into during construction is bigger, so can only be used for excavation construction, can't be used for non-excavating construction; What another kind of shaped-steel strip adopted is square tube, and the shortcoming of this kind composite winding pipe is: add man-hour in actual production, square tube is carried out spiral twine very difficult because of the enclosed construction of square tube causes; In addition since square tube after spiral twines, last circle does not have overlap joint each other with back one circle, thereby causes the axial tensile strength of this kind composite winding pipe less.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of and can be used for non-excavating construction, actual processing is fairly simple, axial tensile strength is bigger steel-band reinforced steel plastic composite wound pipe.
For addressing the above problem, the technical solution adopted in the utility model is: steel-band reinforced steel plastic composite wound pipe, comprise by shaped-steel strip and twine the tube wall skeleton that forms, the inner and outer wall that forms composite winding pipe is twined by plastic tape respectively in the inside and outside surface of tube wall skeleton, the surface of described outer wall is a smooth surface, the cross section of described shaped-steel strip is the shape that is " several " word that comprises a long pin and a short pin, and the short pin of shaped-steel strip is laminated on the long pin of adjacent shaped-steel strip in the axial cross section of described tube wall skeleton.
There is adhesive layer on the surface of described shaped-steel strip.
The surface of the inwall of described composite winding pipe is a smooth surface.
The beneficial effects of the utility model are: because the surface of the outer wall of described composite winding pipe is a smooth surface, so the tractive resistance that runs into during construction is less, so large diameter composite winding pipe also is applicable to non-excavating construction; Cross section is that the shaped-steel strip of " several " font is fairly simple when twining, and long pin makes axial tensile strength of the present utility model bigger with the structure that short pin laminates mutually; Compare with the steel-band reinforced steel plastic composite wound pipe of traditional equal length, the plastic tape that described composite winding pipe consumed is less, under situation about realizing than high ring rigidity, greatly reduces the tubulation cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model steel-band reinforced steel plastic composite wound pipe is described in further detail.
As shown in Figure 1, it is a kind of steel-band reinforced steel plastic composite wound pipe of structure, comprise by shaped-steel strip 1 and twine the tube wall skeleton that forms, the cross section of described shaped-steel strip 1 is the shape that is " several " word that comprises a long pin 11 and a short pin 12, there is adhesive layer 4 on the surface of shaped-steel strip 1, make shaped-steel strip 1 can with inner tubal wall 2 and outer tube wall 3 secure bond, when shaped-steel strip 1 twines, the short pin 12 of back one circle shaped-steel strip 1 is laminated on the long pin 11 of last circle shaped-steel strip 1, leave a determining deviation between long pin 11 of last circle and the long pin 11 of back one circle, in the tube wall skeleton, outer surface twines inwall 2 and the outer wall 3 that forms composite winding pipe by the soft plastic tape that melts attitude respectively, each circle of plastic tape part mutually laminates and pushes bonding, the final tubulose that forms, the surface of described inwall 2 and outer wall 3 is smooth surface.
As shown in Figure 2, it is the steel-band reinforced steel plastic composite wound pipe of another kind of structure, the difference of itself and steel-band reinforced steel plastic composite wound pipe shown in Figure 1 only is: when shaped-steel strip 1 twines, the short pin 12 of back one circle shaped-steel strip 1 is laminated on the long pin 11 of last circle shaped-steel strip 1, the afterbody of the long pin 11 of last circle has partial stack with the back long pin 11 of one circle, when stack was arranged, the intensity and the cohesiveencess of inner tubal wall 2 were better.
