Technical field
The utility model relates to the aqueduct field of plumbing, relates to a kind of fiber reinforced plastic concrete composite pipe inner lining structure band rubber ring structure specifically
.
Background technique
At present, fiber reinforced plastic concrete composite pipe inner lining structure outer surface uses reinforced concrete floor to cover, the bonding mode of its liner and reinforced concrete floor is by cementing, the conjugation of this bonding is not enough, in installation process, due to lifting, the splicing of machinery, can make composite pipe lining and reinforced concrete floor that the possibility loosened occurs, long-term is embedded in underground, is pressed through by weights such as ground earth, vehicles, and concrete layer can be made to a certain extent to produce crack.
In addition, in work progress, pipeline lateral fluid medium enters frp lining and concrete joint surface causes structural failure to liner and concrete joint surface.
In sum, fiber reinforced plastic concrete composite pipe inner lining structure needs to improve.
Model utility content
The technical problems to be solved in the utility model there are provided a kind of fiber reinforced plastic concrete composite pipe inner lining structure band rubber ring structure, and pipeline lateral fluid medium can be avoided to enter frp lining for this structure and concrete joint surface causes structural failure to liner and concrete joint surface.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of fiber reinforced plastic concrete composite pipe inner lining structure band rubber ring structure, comprising:
Be placed in the outer field reinforced concrete floor of composite pipe;
Be placed in the frp lining layer of composite pipe internal layer;
Described frp lining layer surface is provided with bonding layer, this bonding layer is particle shape, be bonded in frp lining layer surface, described frp lining layer outer wall middle part surface indent, inner concave is straight shape cylinder, slope with port joint, frp lining layer outer wall two ends, described frp lining layer two ends outer wall is provided with groove circle, outside described frp lining layer external diameter, be provided with the expansion cushion rubber of water-swellable with reinforced concrete floor inner diameter, expansion glue snare is on groove circle.
Further, described expansion cushion rubber is 2.
Further, described bondline thickness is the parallel distance of the inner concave in the middle part of described frp lining layer to described frp lining layer two ends outer wall upper surface.
Further, described frp lining layer ramp angles is between 30 ° ~ 60 °.
Further, described frp lining layer internal surface is cylindrical surface.
Relative to prior art, the beneficial effects of the utility model are:
1. expansion cushion rubber is positioned over outside frp lining external diameter and concrete inner diameter, and expansion cushion rubber solution pipeline lateral fluid medium enters frp lining and concrete joint surface causes structural failure problem to liner and concrete joint surface.
2. frp lining layer outer wall middle part surface indent, inner concave is straight shape cylinder, is more conducive to the bond effect of reinforced concrete floor.
3. between frp lining layer and reinforced concrete floor, add the bonding layer of hard particles thing, effectively can promote the conjugation between frp lining layer and reinforced concrete floor.
