Description
Technical field
The utility model relates to a kind of multiple tube, especially a kind of frp lining concrete composite pipe belongs to water supply row
Waterpipe engineering device technique field.
Background technique
Glass reinforced plastic pipe, mainly using glass fibre and its product as reinforcing material, with the unsaturated polyester tree of macromolecule component
Rouge, epoxy resin etc. be basic material, using the inorganic non-metallics such as quartz sand and calcium carbonate granular materials be filler as mainly original
Material, major advantage is high-strength light, corrosion resistance, inner surface is smooth, conveying energy consumption is low, long service life, interface close water
Ability is strong, installation and transportation are convenient.But since it belongs to flexible pipe, rigidity is lower, and pipe deforming is big, and pipeline is fragile by external force
Damage, it is more demanding to construction technology and application environment condition.
Pipe of concrete, a kind of traditional piping material, since with good bearing capacity, external force resistance is destroyed and deformability is strong and makes
It makes that cost is relatively low, is once being widely used in water supply and sewerage pipeline system, but since its interface airtightness is poor, internal coarse hydraulic performance
Difference, anticorrosion pipeline service life is not short, the reasons such as tube body heaviness installation and transportation inconvenience and gradually have the tendency that being eliminated；But
More and more to high-bearing capacity large diameter pipeline demand in water conservancy and municipal works in recent years, general traditional plastic tube includes glass
Glass steel conduit is all extremely difficult to the requirement to high-bearing capacity, (though structure wall thickness can be increased by special processes to reach high
Requirement for bearing capacity, but piping cost just will increase dramatically, it is difficult to receive.) and large diameter concrete pipeline must not used.

It can effectively ensure that fixed effect, guarantee the effective integration of glass reinforced plastic circumferential rib band and glass reinforced plastic inner tube.
In a specific embodiment, the deformation displacement problem for not only needing to consider two kinds of composite material axial directions of pipeline, is also wanted
Pipeline radial force and two kinds of composite material stress removings are considered the problems of, to can effectively guarantee the whole of multiple tube
Body, stability, connector one end is tied up by circumferential rib band with glass reinforced plastic inner tube and is fixedly connected thus, and the other end is anchored in mixed
The design on axial stiffener in solidifying soil, the very good solution above problem.Therefore, in another specific embodiment,
3 top of " u "-shaped connecting component is provided at least a pair of of through-hole 7 so as to axial interspersed fixed stiffener 8.The design method exists
In practical application, implantation stiffener carries out reinforcing the usage amount that can effectively control concrete, especially to lightization pipeline
With more important meaning.
In design principle based on above-mentioned specific embodiment, need the considerations of for overall performance and also to consider coagulation
The bearing capacity of native pipe, in another specific embodiment, at least provided with one layer of stiffener, the reinforcement steel in pipe of concrete 2
8 periphery spiral winding of muscle has stirrup 9 to band together；Stiffener 8 is axially mounted along glass reinforced plastic inner tube, connects through " u "-shaped
Corresponding through-hole 7 on relay part, by tying up fixation, stiffener 8 and the closely coupled formation of " u "-shaped connecting component are integrally total
Same stress.As specific design structure, which has two sides, is respectively arranged on the side corresponding
Through-hole, for two through-holes along tubular axle combined to setting, the combination of multiple groups " u "-shaped connecting component makes every group of corresponding " u "-shaped interconnecting piece
Through-hole on part is located on the same line.Penetrating for stiffener can be completed with which in this.More specifically, the reinforcement
Reinforcing bar is located in concrete.Which can not only guarantee the rigidity and bearing capacity of pipe of concrete, while also improve whole multiple
The performance for closing pipe, especially forms more stable cage body after penetrating stiffener.For example, the through-hole 7 is 2 pairs, Mei Duitong
Corresponding 1 stiffener in hole passes through, and is formed by concreting, and the stiffener 8 of formation is two layers, i.e. internal layer and outside
Layer, the circle diameter of internal layer are less than the circle diameter of outer layer.Which can effectively ensure that the rigidity of large scale tube body.Therefore,
Stiffener is also distributed and along glass reinforced plastic inner tube centerline axis at circumference array to distribution after passing through through-hole.As more specific
, which is made of metal material, such as: reinforcing bar or steel wire.
As more specifical, in another specific embodiment, connector uses metal material or rigid composite material
It is made.But since it is desired that therefore pre-buried setting in advance for the ease of processing, reduces cost, thus using Steel material.
