Description
Technical field
It the utility model is related to a kind of bracing means.
Background technology
Coastal areas of Fujian province has largely across river, bridge spanning the sea, and these bridges are all the bridges of middle Long span, its bridge pier
（Part）It is all located at the pile foundation annual most of the time below day ordinary water level.Pile foundation may occur as soon as defect in work progress
Stake, also or in use because river washes away, seawater corrosion, sand dredger excessively adopts sand, and passing ships hit, top vehicle
The overload of load and cause bridge pier and pile foundation such as the disease such as concrete scaling, the exposed corrosion of reinforcing bar occur.These diseases can be brought
Serious potential safety hazard, therefore the bridge strengthening demand in coastal areas of Fujian province also can be more and more.In recent years, do not arrange under water
Water reinforces the focus for becoming numerous engineering circles personnel researchs.The reinforcing of not draining eliminates this traditional nondominant hand of cofferdam
Section so that easy for construction, the duration shortens, and reinforcement cost reduces.Underwater not stabilization by drainage construction method mainly has FRP reinforcings at present
Method, jacket method and reinforcing underwater structure by fiber-reinforced composite material grid ribs as described in the patent No. " 200910080051 "
Method.FRP carries out not stabilization by drainage and is only suitable to shallow water reinforcing, and FRP itself bondings are not firm.Both reinforcing modes are main afterwards
Thinking is similar, is sunk under the water using sleeve pipe and wraps pier stud, then does not disperse under priming petock in the gap between sleeve pipe and pier stud
Mortar, complete to reinforce.But due to the limitation of connected mode, it both can not realize underwater assembled sleeve pipe.This will limit it and be applicable
Scope, can not under water exist and be used in the bridge of binder.Therefore the defects of being badly in need of overcoming sleeve pipe can not complete assembly under water, it is full
The application of sufficient engineering needs.
The content of the invention
The utility model makes improvement for the above-mentioned problems of the prior art, i.e., skill to be solved in the utility model
Art problem is to provide a kind of bracing means, and can not only solve existing engineering in practice can not assembled concrete slab under water
Defect so that at the construction field (site) can be directly assembled under water after the concrete pipe sheet that has been prefabricated in the factory；This connection side simultaneously
Formula has certain prestressing force, can improve the anti-crack ability of sleeve pipe, improves globality, and water is sunk to after being also applied for assembly waterborne
Bottom reinforces.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of bracing means, including multiple arcs
Section of jurisdiction, be provided with preformed hole in section of jurisdiction, by setting curved screw rod in the preformed hole of adjacent section of jurisdiction, curved screw rod both ends are set
Put nut and realize being fixedly connected for adjacent section of jurisdiction, the pipe sheet assembling of the multiple arc is sleeve pipe.
Further, it is provided with cushion block on section of jurisdiction inner arc wall, preformed hole extends through cushion block, and nut is one flat by cushion block
Anchored in face of curved screw rod.
Further, section of jurisdiction material is concrete.
Further, preformed hole is realized reserved by pvc pipe.
Further, filling underwater mealing material in preformed hole.
Further, underwater mealing material is underwater epoxy resin.
Further, cushion block is triangle cushion block.
Further, adjacent section of jurisdiction is connected by multiple curved screw rods.
Further, the curvature of curved screw rod and the curvature of preformed hole are identical.
Compared with prior art, the utility model has the advantages that：Can assembled sleeve pipe under water, be suitable for not
The underwater Pier Column Reinforcing of draining, advantage is particularly evident in deep water reinforcing, without extras, overcomes the good sleeve pipe of assembly waterborne
Because the problem of binder can not sink be present；Sleeve pipe good integrity after anchoring, there is certain prestressing force, provided due to nut
Prestressing force can resist the hydraulic pressure at deep water, can be very good improve concrete pipe sheet connection cracking resistance, good airproof performance,
Unified entirety can be formed therewith very well after being starched under its internal priming petock regardless of loose sand, given the certain prestressing force of pier stud to be reinforced and protected
Shield；Cost is low, it is only necessary to which precast concrete section of jurisdiction and bolt and nut can complete assembly, and have good intensity；Construction
Speed is fast, and when demand is promptly reinforced, benefit is especially prominent；The projection of triangle cushion block can be formed internally after casting concrete
Shear connector, section of jurisdiction and the bonding of the underwater concrete poured can be improved, improves integral anti-shearing performance；Concrete pipe sheet passes through spiral shell
Stem nut can need appropriate arrangement of reinforcement to ensure entirety after being connected as sleeve pipe as the template of casting concrete, institute's casting concrete
Property, so outside concrete sleeve can play a part of constraint inner concrete, improve the overall antidetonation of combining structure
Performance and stress performance；Connected mode of the present utility model, engineering practice is taken into full account, tackled underwater assembled proposition
One simple and effective connected mode, there is preferable Practical Project benefit.
