Abstract
The utility model relates to a large aperture concrete plastic tube that is used in a water supply and drainage system, which is designed to overcomes the drawbacks of concrete pipes in the prior art, including poor corrosion resistance, high friction coefficient of inner wall, low pressure resistance, short service life, high cost of plastic pipe, and low rigidity, etc. The utility model comprises a pipe body, wherein, the pipe body comprises a plastic inner pipe and a outer cast concrete pipe, wherein, pins embedded into the concrete pipe are arranged evenly on the outer wall of the plastic inner pipe. With above structure, the plastic inner pipe is coupled to the concrete pipe firmly; the plastic inner pipe is characterized in high chemical resistance and low friction coefficient, and thereby can improves the water transmission capacity, and is hygienic and reliable, and can reduce the cost; in addition, since the plastic inner pipe is coupled to the concrete completely, the strength and rigidity of the pipe are enhanced greatly, and the compression strength is 2 times higher than concrete pipes without inner plastic pipe.
Description
Technical field
The utility model relates to the large diameter concrete pipe of using in a kind of confession, the drainage system, and specifically a kind of concrete lining is moulded pipeline, is a kind of improvement to the existing concrete pipe.
Background technique
Now there are concrete pipe and plastic tube in the city for the pipeline that uses in, the drainage system.The advantage of concrete pipe is that cost is low, and its shortcoming is that chemical resistance is poor, and pipe top compressive strength is low, interface tube place easy to leak, and the inner tube wall friction factor is big, belongs to rigidity tubing, is subject to the geology sedimentation and reduces working life; Because there are above-mentioned many shortcomings in concrete pipe, in the present novel pipeline material, the plastic pipe development is very fast.But also there are some shortcomings in existing plastic pipe, the one, and cost is low high; The 2nd, the ring stiffness of plastic pipe is lower.
Summary of the invention
The utility model is for technical problem such as solve concrete pipe corrosion-resistant that prior art exists, the inwall friction factor is big, compressive strength is low, working life is short, and plastic tube cost height, ring stiffness are lower.
In order to solve the problems of the technologies described above, the utility model comprises body, it is characterized in that: described body comprises the plastic inner lining pipe and at its outer concrete pipe of pouring into a mould, is provided with the protruding nail that embeds in the concrete on the plastic inner lining pipe outer wall equably.
Also have following feature in the utility model: described protruding nail is that " Y " font is or/and inverted cone.
Also have following feature in the utility model: described plastic inner lining pipe is the high density polyethylene (HDPE) internal lining pipe, and its thickness is 2～6mm.
The utlity model has following advantage and good effect: because the utility model has adopted said structure, plastic inner lining pipe and concrete pipe can closely combine, the plastic inner lining pipe has chemical resistance, friction factor is low, make conveyance power of water raising in the pipe, health is reliable, has also reduced cost 4; In addition, the plastic inner lining pipe combines with concrete is whole, and tubing top intensity and ring stiffness are greatly improved, and the concrete pipe that compressive strength rate does not have liner has improved twice.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 the utility model sectional drawing.
1, plastic inner lining pipe; 2, concrete pipe; 3, the protruding nail of " Y " font; 4, the protruding nail of inverted cone.
Embodiment
Referring to Fig. 1, the utility model comprises body, body comprises plastic inner lining pipe 1 and the concrete pipe of pouring into a mould at its skin 2, be provided with the protruding nail that embeds in the concrete on plastic inner lining pipe 1 outer wall equably, protruding nail is protruding nail 3 of " Y " font or the protruding nail 4 of inverted cone, also can be provided with protruding nail 3 of " Y " font and the protruding nail 4 of inverted cone simultaneously.Described plastic inner lining pipe 1 is the high density polyethylene (HDPE) internal lining pipe, and its thickness is 2～6mm, decides on tubing condition such as buried depth, level of ground water height in engineering.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
Claims (3)
