Description
Technical field
A kind of drainage pipeline is the utility model is related to, more particularly to a kind of steel band enhanced polyethylene helical screwed pipe.
Background technology
Bellows is widely used in the industries such as municipal drainage, cable cover(ing), sewage disposal, it will usually buried laying, it is buried
The plastic film capicitor high-line conduit of laying can bear load and the pressure of outside.Ring stiffness is plastic buried pipe critical external compressive resistance load energy
The comprehensive parameters of power, if the ring stiffness of tubing is too small, tubing may occur excessive deformation or lateral deflection unstable failure occurs.Ripple
Pipe is universal all there are the problem of restorative difference, is easier to deform.
Steel band reinforced polyethylene spiral ripple pipe is basic using high density polyethylene (HDPE), with the steel band of surface coating adhering resin
Waveform is shaped to as main support structure, and compound integral double-walled helical corrugation pipe is wound with polythene material.And steel
Band enhancing polyethylene helical bellows once deform, and if things go on like this, the position of deformation holds very much due to being subject to larger stress
Easily occur fractureing or damaged, steel band reinforced polyethylene spiral ripple pipe is all to be embedded in underground during due to construction, once occur it is damaged,
Maintenance and replacement are extremely inconvenient, expend substantial amounts of manpower and materials.
The Chinese patent of Publication No. CN105443878A discloses a kind of polyethylene steel belt enhancing bellows, including cylinder
Shape tubing matrix, the cylinder tubing matrix is mainly made of spiral winding and melting adhered multiple recombiner units, described
Recombiner unit includes inner and outer wall, on the outer wall formed with spiral hollow form fin, in the cavity of the hollow form fin
The teel band identical with hollow form fin shape is connected with wall；And the both ends of teel band are extended to form to both sides
Foot, this bipod are embedded between the inner and outer wall of recombiner unit.
Although above-mentioned this polyethylene steel belt enhancing bellows can be by the inside and outside wall of ambient pressure gentle transition to tubing
On, reduce tubing it is under pressure when damage, but when ripple pipe outer wall is subject to larger stress for a long time, since pressure direction can only be to
Power, can not be dispersed to other directions by the axial dispersion of bellows, and teel band local deformation can be caused serious, and then be influenced
The using effect of bellows.
Utility model content
The purpose of this utility model is to provide a kind of steel band enhanced polyethylene helical screwed pipe, and having can be by pressure direction point
Be dissipated to the radial direction of bellows, thus mitigate ripple tube body it is under pressure when the effect that is deformed by component.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of steel band enhanced polyethylene helical screwed pipe, including ripple tube body, teel band one and polyethylene layer, it is described

And the effect of power can be further shared to the axial dispersion of ripple tube body, teel band two, make the effect of power to bellows
The radial dispersion of body, thus mitigate ripple tube body it is under pressure when the degree that is deformed by component.
Further, the section of the teel band two is in " Ω " shape, the teel band two and bellows outer body
For arc-shaped transition.
By using above-mentioned technical proposal, teel band two can make enhancing with bellows outer body in arc-shaped transition
Steel band two is not susceptible to deviate, and stability is high, further increases the ring stiffness of ripple tube body, moreover it is possible to which ambient pressure is gentle
Be transitioned into bellows body tube wall radially, reduce its it is under pressure when damage.
Further, gap is left between the described one end of teel band one and teel band two away from ripple tube body.
By using above-mentioned technical proposal, when ripple tube body is smaller by external pressure effect, one stress deformation of teel band
After can't touch to teel band two, only need teel band one to disperse pressure at this time, can thus reduce teel band
Two usage time, plays a protective role.
Further, cushion pad is equipped with the gap.
By using above-mentioned technical proposal, cushion pad can divide the effect of ambient pressure with receiving portion, while will can also press
At power gentle transition to teel band two, cushioning effect is played.
Further, it is equipped with reinforcing rib structure in the fin.
By using above-mentioned technical proposal, reinforcing rib structure can increase the intensity and rigidity of fin, so as to further increase
The ring stiffness of high-amplitude wave line tube body.
Further, the reinforcing rib structure is bracing piece, and the bracing piece is fixedly connected with arch section, the reinforcement
Bar and bellows body are axially in parallel.
By using above-mentioned technical proposal, bracing piece can increase the intensity and rigidity of teel band one, while can make
Axial dispersion of the pressure by leg more uniformly to ripple tube body.
Further, the bracing piece is evenly arranged with weekly 2~8 along the winding direction of teel band one.
By using above-mentioned technical proposal, bracing piece, which is uniformly arranged and is set to 2~8, can further improve bellows sheet
The ring stiffness of body entirety.
Further, thermoplastic resin layer is equipped between the ripple tube body and teel band one.
By using above-mentioned technical proposal, thermoplastic resin layer bonds when ripple tube body can be made to be molded with teel band one
It is more firm.
Further, cushion is equipped between the teel band one and polyethylene layer.
By using above-mentioned technical proposal, cushion is extruded with buffering and restitution well, Ke Yiyou to external force
Effect prevents ripple tube body to be caused to deform because external force extrudes.
Further, the cushion is polyethylene.
By using above-mentioned technical proposal, polyethylene has outstanding protecting against shock, vibration proof, antistatic, anticorrosion
Function, can effectively prevent ripple tube body causes to deform because external force extrudes.
In conclusion the utility model has the advantages that：
1. the setting of teel band two can make bellows body when being subject to weight, further by extruding force to bellows
The radial dispersion of body, avoids ripple tube body from being locally subject to excessive pressure；
2. the setting of bracing piece can increase the overall ring stiffness of ripple tube body；
3. thermoplastic resin layer is combined more firm when ripple tube body can be made to be integrally formed with teel band one；
4. cushion have to the external force of extruding well buffering and restitution, can effectively prevent ripple tube body because
External force extrudes and causes to deform.
