Abstract
The utility model provides a glass steel pipe lined with reinforced concrete, which belongs to the field of composite pipes, and structurally comprises a pipe body, the interior of the pipe body is a cavity channel, the pipe body is formed by compounding an inner liner layer with an outer protective layer, the inner liner layer is sheathed in the outer protective layer, the inner liner layer comprises at least one glass steel layer, the outer protective layer comprises at least one reinforced concrete layer, the outer diameter of the outer protective layer is taken as the outer surface of the pipe body, and the inner diameter of the inner liner layer is taken as the inner wall surface of the pipe body. The glass steel pipe lined with the reinforced concrete has simple structure and high corrosion resistance, does not need to take any protective measure, and is long in service life, and can meet different construction requirements. For the glass steel pipe lined with the reinforced concrete, the reliability, the advancement and the economy of a pipeline section can be upgraded to a new level, thereby being a novel energy-saving and environment-friendly product.
Description
Technical field
The utility model belongs to the water supply and sewerage pipeline technical field, specifically relates to a kind ofly be composited environmental protection, tubing corrosion-resistant, energy-efficient, with low cost by glass fibre reinforced plastics and reinforced concrete floor.
Background technique
In the engineering construction of current every plumbing, modal pipeline mainly contains cement pipe, cast iron tube, steel pipe, aluminium-plastic composite pipe, high density polyethylene pipe and Glass Steel Tube etc.In these conduit types, cement pipe intensity is low, and density is big, and tube wall easily grows the bacterium that water quality is had pollution, stops using at present; And cast iron tube, steel pipe are not corrosion-resistant, the cost height, and weight is big, is difficult for transportation; Aluminium-plastic composite pipe just is used for small-bore cold water pipe, and its size has only 40 usually---60mm, and cost of production is very high; The intensity of high density polyethylene pipe is low, and is not high pressure resistant, and distortion is big, the cost height, and dexterous every length has only 2---3m, install inconvenience.The fiber reinforced plastic pipe specific strength, aspect excellent performances such as decay resistance, but cost is very high and installation requirement is high, and certain restriction is also arranged in the use.
And the tubing of selecting engineering to use not only will be considered technology, the reliability of quality, and advance also will be considered its Economy.But in the comprehensive above-mentioned cited kind of tube types, no matter be to select any tubing for use, all can't reach best requirement, and in the later stage that engineering construction finishes, the cycle in its working life is shorter, operation and maintenance cost is high, and this is the reason that causes the cost of present every pipework construction to hit new peak repeatly, does not also meet the fundamental state policy of the sustainable development that China formulates.
Summary of the invention
At the existing problem of background technique, the utility model is designed a kind of environmental protection of simple in structure, reasonable in design, good airproof performance, frp lining concrete reinforced pipe corrosion-resistant, energy-efficient, with low cost.
For achieving the above object, the technical solution of the utility model is: a kind of frp lining concrete reinforced pipe belongs to composite pipe.Structure comprises a body, in the body is cavity passage, body is composited by inside liner and outer protective layer, inside liner is set in the inside of outer protective layer, inside liner comprises the frp layer of one deck at least, outer protective layer comprises that one deck is by the reinforced concrete floor of concrete and reinforced concrete combination at least, and the external diameter of outer protective layer is the outer surface of body, and the internal diameter of inside liner is the internal face of body.
By such design, the utility model has effectively solved the rigidity and the unmatched problem of intensity of pure fiber fw frp structural pipe wall, when improving pipeline rigidity, reduce manufacture cost, and inner-walls of duct is smooth, on-way resistance is little, freight and maintenance cost are low, and environmental protection is corrosion-resistant, energy-efficient, and its comprehensive economy is with the obvious advantage.
Description of drawings
Fig. 1 is a structural perspective of the present utility model;
Fig. 2 is structure master's pseudosection of the present utility model.
Among the figure, 1, body, 2, outer protective layer, 3, inside liner.
Embodiment
Extremely shown in Figure 2 according to Fig. 1, middle body 1 for cavity passage is by inside liner 3 and outer protective layer 2 bonding being composited, inside liner 3 adopts the glass fiber reinforced plastic layer of simple layer, it is frp layer, the thickness of this frp layer reaches 2.5mm, inner face is a smooth surface, outer protective layer 2 adopts the reinforced concrete floor of simple layer, this reinforced concrete floor is mixed by concrete and reinforced concrete, because the internal diameter of inside liner 3 is less than the internal diameter of outer protective layer 2, the external diameter of inside liner 3 is less than the external diameter of outer protective layer 2, the internal diameter of the external diameter of inside liner 3 and outer protective layer 3 is corresponding to the same, inside liner 3 can rely on self rigidity and stiffening rib directly to embed the inside of outer protective layer 2 and be adhesively fixed, and the external diameter of outer protective layer 2 is as the outer surface of body 1, and the internal diameter of inside liner 3 is as the internal face of body 1.
The utility model overall weight is light, has avoided the generation of the uneven settlement phenomenon of whole piece pipeline in very abominable edatope, and the inner wall smooth flow of body is big, can be connected with other tubing easily, to satisfy different construction requirements.
According to technique scheme; those skilled in the art according to actual needs; also can design the pipeline of more different structure forms; but the foregoing description is only enumerated for explanation the utility model; be not to be used to limit the utility model; the structure of any effects equivalent based on the conversion of the technical program institute all belongs to protection domain of the present utility model.
Claims (4)
1. a frp lining concrete reinforced pipe comprises a body, it is characterized in that: be cavity passage in the body, body is composited by inside liner and outer protective layer, and inside liner is set in the inside of outer protective layer.
