Abstract
The utility model discloses a kind of concrete plumbing normal pressure pipeline adopting thin frp lining, comprise inside liner; Described inside liner is thin glass fibre reinforced plastics plate body or thin fiber reinforced plastic barrel; Frp lining sealed interface is provided with inside described inside liner; The outer surface of described inside liner is provided with glass fibre reinforced plastics anchoring piece; Described inside liner outer cover is connected to reinforcement cage; Described reinforcement cage both sides and and frp lining layer between built concrete according to die size.The utility model fully can solve a difficult problem for this bi-material of glass Steel concrete separation and effectively reduce the cost that glass fibre reinforced plastic material does pipe lining.
Description
Technical field
The utility model relates to a kind of concrete plumbing normal pressure pipeline adopting thin frp lining, belongs to the manufacture pipe fitting field of water supply and draining novel pipeline.
Background technique
From nineteen fifty, the U.S. has built in the world since Article 1 PVC inner lining concrete composite tube in Los Angeles, this pipeline is still the blowdown tubing of the corrosion resisting liner that the whole world comparatively generally uses so far, and Guangdong Province of China has also issued province's standard of this tubing in May, 2007; But because PVC is a kind of thermoplastic cement material, make the PVC liner time of concrete duct grow easy degradation and decomposition and produce crack, come off the even overall concrete duct that departs from; Especially the freexing tolerance of PVC material and poor heat resistance, poor rigidity, in addition constructing in manufacture process because of the factors such as the skills involved in the labour of the inappropriate property of technique, manufacture method, workman are inadequate impact, cause the serious quality problems of PVC inner lining concrete pipeline to happen occasionally, prove the time limit of its working life far below designing requirement originally by engineering practice for many years; Report is pointed out according to investigations, and the loss that in global range, PVC inner lining concrete pipeline causes due to above-mentioned many defects is very huge; In China, this type of accident also has report frequently.
Model utility content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of concrete plumbing normal pressure pipeline adopting thin frp lining; Use glass fibre reinforced plastics thin plate or use thinner glass fibre reinforced plastics cylinder to do the novel tube of liner; Not only can replace PVC inner lining concrete pipe also can be used for gravity flow water supply line for drainage pipe.
(2) technological scheme
The concrete plumbing normal pressure pipeline of the thin frp lining of employing of the present utility model, comprises inside liner; Described inside liner is thin glass fibre reinforced plastics plate body or thin fiber reinforced plastic barrel; Frp lining sealed interface is provided with inside described inside liner; Described inside liner outer surface is provided with glass fibre reinforced plastics anchoring piece; Described inside liner outer cover is connected to reinforcement cage; Described reinforcement cage both sides and and inside liner between built concrete.
Further, described glass fibre reinforced plastics anchoring piece and inside liner are bondd by strength adhesive.
Preferably, described glass fibre reinforced plastics anchoring piece is glass fibre reinforced plastics I-shaped structure.
Preferably, described glass fibre reinforced plastics anchoring piece is glass fibre reinforced plastic square structure.
Preferably, described glass fibre reinforced plastics anchoring piece is the flat arc body structure of glass fibre reinforced plastics or semicircular structure.
Preferably, described glass fibre reinforced plastics anchoring piece is glass fibre reinforced plastics triangular structure.
Preferably, described glass fibre reinforced plastics anchoring piece is glass fibre reinforced plastics Y-shaped structure.
Preferably, described glass fibre reinforced plastics anchoring piece is the vertebra structure of fine stone aggregate synthesis.
Preferably, described glass fibre reinforced plastics anchoring piece is waved glass steel anchoring ring structure.
(3) beneficial effect
Compared with prior art, the concrete plug of the thin frp lining of employing of the present utility model, use mechanism anchorage method, utilize anchoring key and in conjunction with the tension force of reinforced plastic plate, glass fibre reinforced plastics and these two kinds of diverse materials of physicochemical properties of concrete are combined securely, breaches and use thinner glass fibre reinforced plastic material to do pipe lining layer to be just difficult to solve technical barrier together with concrete strong bonded in the past; Solve and adopt comparatively heavy sheet glass steel cylinder body to do concrete duct inner lining material to cause product cost high, engineering circles is difficult to promote the use of or adopt simple Chemical Felter to go do not have the shortcomings such as effect in conjunction with methods such as bi-materials, avoids causing serious qualitative problems of construction.

Embodiment
The concrete plumbing normal pressure pipeline of the thin frp lining of employing as shown in Figure 1, comprises inside liner 2; Described inside liner 2 is thin glass fibre reinforced plastics plate body or thin fiber reinforced plastic barrel; Frp lining sealed interface 4 is provided with inside described inside liner 2; Described inside liner 2 outer surface is provided with glass fibre reinforced plastics anchoring piece 3; Described inside liner 2 outer cover is connected to reinforcement cage; Described reinforcement cage to be arranged between punching block and inside liner and to have built concrete 1.
Glass fibre reinforced plastics anchoring piece 3 is as shown in Figure 2 glass fibre reinforced plastics I-shaped structure 3a, glass fibre reinforced plastic square structure 3b, the flat arc body structure of glass fibre reinforced plastics or semicircular structure 3c, glass fibre reinforced plastics triangular structure 3d, glass fibre reinforced plastics Y-shaped structure 3e, the vertebra structure 3f of fine stone aggregate synthesis or waved glass steel anchoring ring structure 3g; Seven kinds of above-mentioned anchoring keys comprise their extension form, the mechanical firmness of anchoring ring and glass fibre reinforced plastics thin plate or glass fibre reinforced plastics cylinder, ensures that composite tube can not be separated with the construction layer of concrete pipe when bearing external and internal pressure and is outside tension force by making full use of reinforced plastic plate and anchoring key and concretely combines closely.
As shown in Figure 3, working process of the present utility model is: glass fibre reinforced plastics anchoring piece and glass fibre reinforced plastics thin plate are fixed by strength adhesive, by firmly install the glass fibre reinforced plastics thin plate of anchoring key or glass fibre reinforced plastics cylinder put internal mold into by tension adjustment and become circle be close to pipeline internal mold outer surface after fixing, and sealing joint work is carried out to such as jointed frp lining, then reinforcement cage is placed between glass fibre reinforced plastics cylindrical body and punching block external mold, carry out steel bar cage protecting layer adjustment positioning work, get final product vertical placement of concrete vibrating forming, and by applying the joint socket of pressure initiation pipeline to head bell, curing and demolding, carry out reinforcement sealing to frp lining layer as jointed position subsequently to repair, and preservative treatment is carried out to the joint socket of concrete pipe, form frp lining modified concrete composite tube.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
