Description
Technical field
The utility model relates to the aqueduct field of plumbing, relates to a kind of fiber reinforced plastic concrete composite pipe flat board specifically and rolls inner lining structure.
Background technique
Aqueduct is used for the fields such as urban water, urban sewage, sewage treatment works's sewage transport, reservoir water delivery.
The concrete water transmission pipe used in early days, this pipe is that reinforcing bar and cement casting form, and be applied to reservoir water delivery, and this concrete water transmission pipe bearing capacity is too low, there is potential safety hazard.Once have an accident, very large disaster can be caused.
Along with the continuous progress of modern science and technology, concrete water transmission pipe is withdrawn from the market gradually, is substituted by some other pipeline, but the part that also comes with some shortcomings, specific as follows:
1, Glass Steel Tube liner: pressure-bearing scope is 0.2-2Mpa, adopt that the manufacture cost of groove type method of construction, pipeline is high, equipment cost is higher.
2, steel pipe: pressure-bearing scope is determined according to thickness of slab, adopt groove type construct or jacking-type method of construction, pipeline manufacture cost high, equipment cost is low.
Find out thus, Glass Steel Tube manufacture cost and equipment cost are all higher, and single equipment investment all will reach more than 2,000,000 RMB, and because equipment part is comparatively large, need large-scale factory building to produce, therefore factory building drops into and at least all wants more than 3,000,000 RMB.No matter be in hydraulic pressure resistance ability for steel pipe, or method of construction and cost of production aspect can match in excellence or beauty with other pipelines, but because tube outer wall is wanted and soil friction in jacking construction process, corrosion-inhibiting coating is easy to breakage, so will significantly reduce the working life of pipeline.
In sum, traditional fiber reinforced plastic concrete composite pipe flat board rolls inner lining structure to be needed 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 flat board and rolls inner lining structure, and this inner lining structure cost is low, seamless link docking technique.
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 flat board rolls inner lining structure, it comprises outermost reinforced concrete floor, also comprise frp lining layer, described frp lining layer is in logical heart cylindrical body, itself and reinforced concrete floor, by a bonding layer adhering junction, described frp lining layer are provided with waterproof docking end face.
Further, described bonding layer is by laying fine sand powder or metal or inorganic, the organic hard particles thing particle adherence layer bonding with gel.
Further, described docking end face is by several continuous print dentation end faces or continuous print semicircle end face slitless connection.
Further, described frp lining layer is rectangular after launching along cylinder line, and this rectangular long limit is continuous print dentation end face or continuous print semicircle end face.
Further, described bondline thickness is between 2 ~ 5mm.
Relative to prior art, the beneficial effects of the utility model are:
1. frp lining rolls into cylinder by a rectangular glass epoxy, be provided with at frp lining skin and lay fine sand powder or metal or inorganic, the organic hard particles thing particle adherence layer bonding with gel, it is strong that bonding layer has cementitiousness, the feature of long service life.
2. slitless connection technology, continuous print dentation or continuous print semicircle are arranged in two long limits of the rectangular slab of frp lining, and be mutual snap-in bonding after making it docking, this mode is easily docked, and makes operation simpler.
3. slitless connection can also be arranged to other non-burnishing surface mode.

Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 1 ~ 4, a kind of fiber reinforced plastic concrete composite pipe flat board of the present utility model rolls inner lining structure, it comprises outermost reinforced concrete floor 1, also comprise frp lining layer 3, described frp lining layer 3 is in logical heart cylindrical body, itself and reinforced concrete floor 1 are by bonding layer 2 adhering junction, and described bonding layer 2 thickness is between 2 ~ 5mm.Described frp lining layer 3 is provided with waterproof docking end face 4.The main application of weight stream of the utility model, gravity flow is also known as stream of handling up, and gravity flow flow velocity is generally no more than 20 ~ 30cm/s.Described frp lining layer 3 is rectangular after launching along cylinder line, this rectangular long limit is continuous print dentation end face 41 or continuous print semicircle end face 42, frp lining layer 3 is rolled by rectangular to form, be rolled into cylindrical shape, docking site is by dentation end face 41 or semicircular end-face 42 clamping mutually, and end is also the tackiness agent bonding using bonding layer 2 to use.And described bonding layer 2 is by laying fine sand powder or metal or inorganic, the organic hard particles thing particle adherence layer bonding with gel, this adhesive bond strength is higher, the feature such as corrosion protection, long service life, be applied in frp lining structure of the present utility model, also the degree of adhesion of reinforced concrete floor 1 and frp lining layer 3 is greatly improved, reinforced concrete floor 1 and frp lining layer 3 is made to bond more firmly, stablize than the mode of traditional direct use reverse mould, in the process of pipe laying, crack can not be there is.
Please refer to accompanying drawing 5 ~ 6, described docking end face 4 is by several continuous print dentation end faces 41 or continuous print semicircle end face 42 slitless connection, this docking mode, can effectively make frp lining port not produce slip, the later stage installation, use also not easily produce distortion.
Docking end face 4 also can adopt other out-of-flatness face to process, as long as the continuity port with mutual screens is just passable.
The foregoing is only preferred implementation of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
