In recent years, along with the attention of country, particularly in urban constructions such as the rainwater in city and sewage treatment to environment; The use of various pipelines is more and more, and particularly the use of large-bore plastics pipeline has very big development, but the ring stiffness of large-bore plastics pipeline has restricted further developing of plastic pipe engineering again than hanging down; Picture polyethylene (PE) double-wall corrugated pipe, polyethylene (PE) entwining tube relatively are fit to the small-bore and plastic pipe below 1 meter, and in 1 meter of diameter and above plastic pipe, the production of PE entwining tube and PE double-wall corrugated pipe that ring stiffness reaches SN8 is relatively more difficult; Even reached technical requirements; The cost of production of tubing is also very high, on the existing market, also is difficult to find these satisfied two kinds of tubing, in PE steel band reinforced pipe; 1.5 meters of diameters and above pipe; Therefore want ring stiffness and reach also difficulty very of SN12.5, on the existing market, press for heavy caliber, high ring rigidity, the more moderate again pipe of cost satisfies the demand in market simultaneously.
Summary of the invention
The technical problem that the present invention will solve is: provide the low highstrenghtpiston's concrete of a kind of cost compound enhancing pipeline.
In order to solve the problems of the technologies described above, the present invention includes the plastic tube of double-layer tube wall, have cavity between the double-layer tube wall of plastic tube, be filled with concrete in the described cavity.
For the ease of making, described plastic tube is a double-wall corrugated pipe, is filled with concrete in the tube wall bellows chamber of double-wall corrugated pipe.
For the ease of the filling concrete, be provided with axial through hole in the tube wall of described double-wall corrugated pipe, through hole communicates with all bellows chamber of double-wall corrugated pipe, all is filled with concrete in through hole and the bellows chamber.
For the ease of the filling concrete, described through hole has two, and two through holes are symmetrically distributed with the central axis of double-wall corrugated pipe.
In order to improve intensity, be provided with metal reinforcing in each bellows chamber of described double-wall corrugated pipe.
In order to improve intensity, described stiffening rib is an annular, and stiffening rib is supported on the inner side surface of outer wall of bellows chamber.
For the ease of making, described plastic tube also can be entwining tube, is filled with concrete in the tube wall inner chamber of entwining tube, and the outer wall of plastic tube is provided with a plurality of filling holes that communicate with the tube wall inner chamber of entwining tube.
In order to improve intensity, be provided with metal reinforcing in the tube wall inner chamber of described entwining tube.
In order to improve intensity, described stiffening rib is a spirality, and stiffening rib is supported on the inner side surface of outer wall of entwining tube.
The invention has the beneficial effects as follows: the present invention closely combines plastic pipe and concrete duct; Plastic pipe and concrete duct advantage is separately replenished each other; Make pipeline both have the characteristic of plastic pipe, have the advantage of concrete duct again, reduce engineering cost simultaneously again; Particularly in the large-scale pipeline engineering, its economic benefit is more obvious.The present invention is fit to the demand in current market very much; It has improved the ring stiffness of plastic pipe greatly; Intensity, while with concrete duct have the advantage that the plastic pipe impermeability is good, corrosion-resistant, in light weight, be convenient to construct again; And can reduce engineering cost effectively, particularly in the large-scale pipeline engineering, have more bigger economic benefit.
