Technical field
The present invention relates to a kind of plastic steel composite pipe structure, the manufacture method of the plastic steel composite pipe is further related to.
Background technology
Pipe of concrete is traditional urban discharging pipeline, steel-wire carcass is set in Pipe making mold, during concrete is poured into
Pipe making mold, obtain traditional pipe of concrete.Because the concrete material and steel-wire carcass of pipe of concrete be not corrosion-resistant, coagulation
Soil manages the managed internal pressure masterpiece used time, and concrete material and steel-wire carcass are by stress so that fine fisssure occurs in concrete layer
Line, wet gas, moisture enter inside concrete layer along micro-crack, steel-wire carcass are caused to corrode, and produce booster.Therefore, pass
On the one hand managed interior flow-induced corrosion, another aspect, managed internal pressure power act on easily the pipe of concrete of system, and steel-wire carcass is by corruption in pipe
Erosion, causes body to burst.
Therefore, there is Prestressed concrete cylinder pipe, i.e., ring steel wire mesh frame is wound outside steel cylinder, in steel wire
Network framework upper concrete cover, obtains Prestressed concrete cylinder pipe.Although Prestressed concrete cylinder pipe makes body
Some strength is added, reduces the stress of concrete layer and steel wire mesh frame to a certain extent；But when tube fluid pressure
When larger, overpressure still can make concrete cover micro-crack occur, and steel wire mesh frame, which is appointed, can so be corroded, and be caused quick-fried
Pipe；Meanwhile steel inwall is also easily corroded by tube fluid.

Concrete Filled layer between rigidity ribs and the coagulation being covered on the rigidity ribs and the Concrete Filled layer
Native outer layer.
In the plastic steel composite pipe of the present invention, it is provided with what is formed along the rigidity ribs in the Concrete Filled layer
The tissue layer of helicla flute winding.
In the plastic steel composite pipe of the present invention, the rigidity ribs shape of cross section is I shapes, L-shaped, T-shaped or I-shaped
One kind, the edge of a wing on the narrow side of L-shaped ribs, T-shaped ribs and I-shaped ribs is located in the plastic cement tube wall.
In the plastic steel composite pipe of the present invention, including it is covered in the plastic protection layer of the rigidity ribs appearance.
Technical scheme is used by the two of its technical problem of present invention solution：A kind of plastic steel composite pipe manufacturer is provided
Method, comprise the following steps：
SP1, plastic cement and rigidity ribs be fabricated to band by extrusion molding；
SP2, band is helically-wound shaped through Wrapping formed mould, obtained plastic-steel spirally-wound pipe；
Characterized in that, also include step：
SP3, horizontal support plastic-steel spirally-wound pipe simultaneously drive its rotation, are poured into a mould on the outside of plastic-steel spirally-wound pipe and are filled in plastic-steel-wound
Tube wall is outer, the Concrete Filled layer between rigidity ribs or is filled in that plastic-steel-wound tube wall is outer, between rigidity ribs
Concrete Filled layer and the concrete outer layer that is covered on rigidity ribs and the Concrete Filled layer.
In the plastic steel composite pipe manufacture method of the present invention, the step SP3 is when pouring into a mould the Concrete Filled layer, institute
State Concrete Filled layer point multilayer to pour into a mould, formed between two layers of Concrete Filled layer is poured into a mould, including along the rigidity ribs
Helicla flute winding tissue layer sub-step.
In the plastic steel composite pipe manufacture method of the present invention, the tissue layer is become band with netted braiding.
In the plastic steel composite pipe manufacture method of the present invention, soaked before tissue layer winding, tissue layer is not dripped during winding
Water.
Implement the plastic steel composite pipe and manufacture method of the present invention, compared with the prior art, its advantage is：
1st, plastic-steel spirally-wound pipe has sufficient intensity, and the pressure that overpressure is delivered to outside concrete layer is small, concrete layer
Micro-crack will not be produced；Inside pipe wall is plastic cement tube wall simultaneously, and resistance to corrosion is strong, so as to substantially increase the anticorrosive of multiple tube
Property, booster probability is greatly reduced, improves pipeline safety in utilization；
2nd, in the Concrete Filled layer between pouring into a mould plastic-steel spirally-wound pipe ribs, a point multilayer is poured into a mould, and in two layers of coagulation
Tissue layer is wound between native packed layer, is greatly improved the tack of concrete, improves the poring rate of Concrete Filled layer.

Fig. 1 to Fig. 4 is four kinds of belt structure cross-sectional views in plastic steel composite pipe manufacture method of the present invention.
Fig. 5 is plastic-steel spirally-wound pipe schematic diagram in plastic steel composite pipe manufacture method of the present invention.
Fig. 6 to Fig. 9 is four kinds of embodiment schematic diagrams of plastic steel composite pipe of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Fig. 1, Fig. 6, plastic steel composite pipe 100 of the invention includes plastic cement tube wall 10, the standing helix positioned at internal layer
The rigidity ribs 20 and concrete layer 30 being wrapped on the plastic cement tube wall 10.
In the present embodiment, concrete layer 30 includes being filled in the coagulation of plastic cement tube wall 10 outside, between rigidity ribs 20
Native packed layer and the concrete outer layer being covered on rigidity ribs 20 and the Concrete Filled layer.
In other embodiments, according to plastic steel composite pipe using the requirement to rigidity, concrete layer 30 is to be filled in plastic cement
Tube wall 10 is outer, the Concrete Filled layer between rigidity ribs 20, and the height of the Concrete Filled layer can be less than rigidity and strengthen
The vertical height of rib 20, can also be concordant with the height of rigidity ribs 20.
In order to increase the tack of concrete when pouring into a mould Concrete Filled layer, the cast speed of Concrete Filled layer is improved
Degree, the tissue layer (not shown) for setting the helicla flute formed along rigidity ribs 20 to wind in Concrete Filled layer.
As shown in Figure 1 to Figure 4, shown in Fig. 6 to Fig. 9, rigidity ribs shape of cross section can use I shapes, L-shaped, T-shaped or I-shaped
One kind of shape, the edge of a wing on the narrow side of L-shaped ribs, T-shaped ribs and I-shaped ribs are located in plastic cement tube wall 10.
The appearance of rigidity ribs 20 can cover plastic protection layer, to improve the corrosion resistance of rigidity ribs 20.Rigidity
The appearance of ribs 20 is not provided with plastic protection layer, does not influence the realization of the object of the invention.
The plastic steel composite pipe manufacture method of the present invention comprises the following steps：
The first step, plastic cement and rigidity ribs be fabricated to band by extrusion molding, as shown in Figures 1 to 4.
Second step, band is helically-wound shaped through Wrapping formed mould, obtained plastic-steel spirally-wound pipe 101, as shown in Figure 5.
3rd step, horizontal support plastic-steel spirally-wound pipe simultaneously drive its rotation, and modeling is filled in the cast of the outside of plastic-steel spirally-wound pipe 101
