The patent application technology of Publication No. CN 103205988A discloses the device of a kind of applicable pile foundation underwater sites repairing and reinforcing and applies the construction method of this device, this technology still suffers from following deficiency: 1. need first to install watertight inclosure, then the water in inclosure is drained, that is: still need to be dried construction environment, high to the seal request of device, workload is big；2. this device watertight inclosure material is PVC or steel, concrete curing complete after, remove inclosure, then reinforce after concrete be still under current scour and various erosion, need after a period of time again to reinforce.
Summary of the invention
The purpose of this utility model is to provide a kind of underwater pile bracing means, this device is utilized to carry out underwater pile reinforcing, without building cofferdam and draining, convenient and quick construction, and the FRP material that FRP shell uses has intensity height, corrosion resistant characteristic, once reinforces and can accomplish to protect with the life-span with structure, economical and practical；To solve the problems referred to above that prior art exists.
The technical scheme solving the problems referred to above is: a kind of underwater pile bracing means, it is characterized in that: this underwater pile bracing means includes FRP shell, locating piece and sealing strip, locating piece is bonded at inside FRP shell by adhesive, sealing strip construction time be arranged on FRP tube shell bottom with in the space treating ruggedized construction.
Its further technical scheme is: described FRP shell is made up of m sheet shell, every shell two ends have male contact and famale connector respectively, m sheet shell is assembled into an entirety by male contact and the famale connector at every shell two ends, and the span of m is: m is 2,3 ... or the arbitrary integer between 12.
Described FRP shell thickness is 1～5mm.
Its further technical scheme is: described FRP shell is made up of n-layer cloth of reinforcement fibers and epoxy resin thermoplastic shaping；Described cloth of reinforcement fibers is formed by reinforcing fiber warp thread and reinforcing fiber weft yarns；Reinforcing fiber refers to the one in carbon fiber, glass fibre, basalt fibre, aramid fiber, vinal or polyester fiber；The span of n is: n is 2,3 ... or the arbitrary integer between 10.
Described locating piece is made up of rubber, polyurethane or epoxide resin material casting.
Owing to using technique scheme, the one underwater pile bracing means of this utility model has the characteristics that and beneficial effect:
1, high intensity, corrosion resistant FRP material is used to do protection shell; and after construction; FRP shell need not be removed; this FRP shell can protect grouting material and concrete not by current erosion; avoid the structural deterioration that steel construction and reinforced concrete structure cause because of electrochemical corrosion; improve tradition reinforcement means identical with original structure material reinforced because using, cause a period of time post-reinforcing position the most impaired, situation about need to repeatedly reinforce.
2, during construction, it is not necessary to build cofferdam and draining, convenient and quick construction.
3, without closing bridge deck traffic during construction, on traffic without impact.
Due to above feature, a kind of underwater pile bracing means of this utility model is applicable to the reinforcing of underwater pile within 10 meters under water, has good economic results in society.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of a kind of underwater pile bracing means of this utility model is further described.
