Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of cost low highstrenghtpiston's concrete composite strengthening pipeline.
In order to solve the problems of the technologies described above, the utility model comprises the plastic tube of double-layer tube wall, has cavity between the double-layer tube wall of plastic tube, is filled with concrete in the described cavity.
For the ease of making, described plastic tube is 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, all bellows chamber of through hole and double-wall corrugated pipe communicate, and all are 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 symmetrical 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 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 spirality, and stiffening rib is supported on the inner side surface of outer wall of entwining tube.
The beneficial effects of the utility model are: the utility model closely combines plastic pipe and concrete duct, plastic pipe and concrete duct advantage is separately replenished mutually, make pipeline both have the characteristic of plastic pipe, has advantages of again concrete duct, reduce again simultaneously engineering cost, particularly in the large-scale pipeline engineering, its economic benefit is more obvious.The utility model is fit to the demand in current market very much, it has improved the ring stiffness of plastic pipe greatly, have advantages of the intensity of concrete duct, simultaneously have again that the plastic pipe impermeability is good, corrosion-resistant, lightweight, constructability, and can effectively reduce engineering cost, particularly in the large-scale pipeline engineering, have more larger economic benefit.

Embodiment
Specific embodiment one
Such as Fig. 1, Fig. 2 and a kind of specific embodiment shown in Figure 3, it is the plastic concrete composite strengthening pipeline of producing on the basis of existing entwining tube 1.
As well known to those skilled in the art, entwining tube 1 is to be formed through spiral winding and bonding by slender pipe.Form the body of a double-layer tube wall, form spiral tube wall inner chamber 1-2 between outer wall 1-1 and the inwall 1-3.
Can insert many reinforcing bars or steel band in the slender pipe of making entwining tube 1, after the winding, form the stiffening rib 3 on the inner side surface that is supported on outer wall 1-1.
Be filled with concrete 2 in the tube wall inner chamber 1-2, outer wall 1-1 offers a filling hole that passes through mutually with tube wall inner chamber 1-2 every a segment distance on the axial direction of entwining tube 1, and concrete 2 injects from filling hole.Also can inject from the two ends of slender pipe.After concrete 2 solidifies, form the high plastic concrete composite strengthening pipeline of structural strength.Concrete 2 can adopt the concrete of existing various existing formulas.In construction, can first entwining tube 1 be arranged on corresponding technique position after, carry out again the filling concrete.
