Abstract

The utility model discloses a corrosion-resistant concrete composite pipeline. The corrosion-resistant concrete composite pipeline comprises a concrete layer, an inner glass reinforced plastic layer is arranged on the inner wall of the concrete layer, an outer glass reinforced plastic layer is arranged on the outer wall of the concrete layer, a quartz sand layer is arranged between the inner glass reinforced plastic layer and the concrete layer, another quartz sand layer is arranged between the outer glass reinforced plastic layer and the concrete layer, and a corrosion-resistant layer is arranged outside the inner glass reinforced plastic layer and the outer glass reinforced plastic layer. The glass reinforced plastic layers are arranged in the concrete layer, and quartz sand is filled among the outer walls of the glass reinforced plastic layers and the inner wall of the concrete layer and can tightly connect the glass reinforced plastic layers with the concrete layer into a whole, so that the integral pipe is guaranteed to have excellent mechanical performance. Meanwhile, the corrosion-resistant layer is arranged outside the inner and outer glass reinforced plastic layers, so that the service life of the concrete composite pipeline can be prolonged.

Description

A kind of anti-corrosion concrete multiple tube
Technical field
The utility model relates to the conveyance conduit for liquid, particularly a kind of anti-corrosion concrete multiple tube that is used for the supply and drain water system of sewage in factory and city.
Background technique
In the sewage supply and drain water system that factory and city are used, generally be to use concrete duct, for also using steel reinforcing in the large-scale concrete duct, cost is lower.But owing in the concrete member slight void is arranged, so its impermeabilisation ability, reinforcing bar sewage medium-term and long-term soak produce rot, intensity and working life that expansion, explosion destroy pipeline, there is the liquid of contaminativity also can be penetrated into pipeline outer wall for conveying, pollute, and this inner-walls of duct is coarse, adheres to easily, accumulating over a long period makes the pipeline constriction in flow area, reduces negotiability.Although can solve with the pipeline of glass fibre reinforced plastics, if the too thin bearing capacity that can affect pipeline of fiber reinforced plastic pipe wall, especially bigbore pipeline; If increase pipeline wall thickness manufacture cost is improved greatly, seem not too economical.
The model utility content
Therefore, the utility model proposes a kind of anti-corrosion concrete multiple tube, can eliminate fully because the restriction of prior art and one or more problems that defective causes.
The utility model additional advantage, purpose and characteristic, a part will be elucidated in the following description, and another part will be significantly for those of ordinary skill in the art by the investigation to following explanation or acquire from enforcement of the present utility model.Can realize and obtain the utility model purpose and advantage by the structure of in the specification of literal and claims and accompanying drawing, pointing out especially.
The utility model provides a kind of anti-corrosion concrete multiple tube, comprise concrete layer, inwall at described concrete layer is provided with interior frp layer, outer wall at described concrete layer is provided with the firm layer of outer glass, between the firm layer of interior glass and concrete layer, be provided with quartz sand layer, also be provided with quartz sand layer between the firm layer of glass and the concrete layer outside, and just be provided with anticorrosive coat in a layer outside at interior frp layer and outer glass.
Preferably, described outer frp layer is made by winding process.
Preferably, described outer frp layer is made of several hoop fiber winding layers, or is made of several hoop fiber winding layers and cross fiber winding layer, or is made of several hoop fiber winding layers and axial direction fibre winding layer.
Preferably, described anticorrosive coat is plastic tube.
The utility model is arranged on frp layer in the concrete layer, and between the inwall of the outer wall of frp layer and concrete layer filling silica sand, by silica sand frp layer and concrete layer are combined closely into an integral body, guarantee that pipeline integral body has good mechanical property, simultaneously, just be provided with anticorrosive coat in layer outside at interior frp layer and outer glass, can improve the working life of concrete composite pipeline.
Description of drawings
Fig. 1 is the structural representation according to the utility model embodiment's anti-corrosion concrete multiple tube.
Embodiment
With reference to the accompanying drawings the utility model is described more fully, exemplary embodiment of the present utility model wherein is described.
As shown in Figure 1, anti-corrosion concrete multiple tube provided by the utility model comprises that just layer 10 and concrete layer 20 are composited by glass, wherein, frp layer is divided into interior frp layer and the firm layer of outer glass, and just be provided with the anticorrosive coat (not shown) in layer outside at interior frp layer and outer glass, described anticorrosive coat is plastic tube.Outer frp layer is made by winding process.The said winding process of the utility model refers to, the hoop by glass fibre or glasscloth twines, hoop winding or cross winding or hoop twines and axially twine glass fibre or the glasscloth winding process that the number of plies, thickness and the sequencing that make outer frp layer reach required mechanical property.
The technical solution of the utility model makes the firm layer concrete multiple tube of glass have good mechanical property, high corrosion resistance, low flow resistance and low manufacture cost by at inside and outside interior frp layer and the firm layer of outer glass of arranging respectively of concrete layer.Concrete, described outer frp layer is made of several hoop fiber winding layers, or is made of several hoop fiber winding layers and cross fiber winding layer, or is made of several hoop fiber winding layers and axial direction fibre winding layer.
Also be provided with quartz sand layer 30 between the firm layer 10 of glass and concrete layer 20, the two combines closely into an integral body by quartz sand layer 30.Concrete, at first make frp layer, at the frp layer setting up period, apply a certain amount of silica sand at its outer surface, make the frp layer after the moulding have more coarse foreign currency, then make the concrete layer of combining closely with frp layer at the frp layer outer wall, by the quartz sand layer that silica sand forms frp layer 10 and concrete layer 20 are combined closely into an integral body.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
