Abstract
The utility model provides an isolating body layer for reinforcing underwater piles, relates to the maintenance and reinforcement of the underwater piles of building structures or bridges, and adopts the method which dispenses with cofferdam during water isolation and arranges an underwater insolating body layer for reinforcement by utilizing prefabricated fiber composite plates. The isolating body layer is prefabricated by fiber composite materials. In order to repair the underwater concrete piles of the bridges, quays and other underwater buildings, the surfaces of which are damaged or sufferer from erosion-corrosion, and to overcome the defects and technological disadvantages of the existing reinforcing method, the insolating body layer is adopted to wrap bodies of the underwater piles and can meet designing and operating requirements, without adopting other treatment measures.
Description
Technical field
The utility model relates to building structure or bridge water king-pile shaft maintenance and reinforcement, does not need to set the cofferdam isolated water, can utilize prefabricated fibrous composite plate that a kind of method that separator layer is reinforced is set under water.
Background technology
Building field to the traditional reinforcement means of water king-pile shaft is: set the cofferdam isolated water earlier, the steel casing is used in the cofferdam more, and carries out back cover with concrete; Extract the water in the casing then out, again the pile body is carried out repairing and reinforcement and handle.Conventional method takes a lot of work, time-consuming, expensive, and have certain degree of difficulty and security risk.
At present, for adopting reinforcing underwater structure by fiber-reinforced composite material grid ribs, be the patent of invention of Beijing Texida Research ﹠ Development of Technology Co., Ltd.'s application in 2009 near reinforcement means of the present utility model.Though also adopted in the method for the treatment of reinforcing underwater structure outer setting separator layer, but its shortcoming is to wrap up earlier afterwards establishing slider, slider is just as ancillary method, and spacer material do not offer some clarification on, and performances such as its intensity, anticorrosive, durability still can't effectively be ensured.
Summary of the invention
The purpose of the present utility model is: in order to repair building surface defectiveness in the water such as bridge, harbour or to be subjected to the underwater concrete pile of erosion corrosion, overcome the many shortcomings and the technologic deficiency of existing reinforcement means, the utility model adopts separator layer that water king-pile shaft is wrapped up, no longer take other treatment measures, can satisfy the requirement of design and use.
For finishing above-mentioned utility model purpose, the utility model is achieved in that
The first step: send professional diver pile body breakage to be carried out concrete knocks out, sander grinding process under water;
Second step: add quartz sand with epoxy resin under water and be configured to mortar bulk or underwater repair mortar, the diver directly spreads upon breakage with mortar, and with doctor blade until repairing the original structure size;
The 3rd the step: according to the height of pile body diameter and breakage, determine prefabricated composite panel around area and corresponding size;
The 4th step: determine the resin demand according to composite panel overlap joint bonding area;
The 5th step: the resin for preparing is evenly brushed on the lap-joint surface with cylinder;
The 6th step: the composite panel overlap joint that the diver will brush resin pastes, and guarantees to paste between lap-joint's plate and the plate closely knit;
The 7th step: back cover is carried out with epoxy mortar under water in separator layer bottom;
The 8th step: irritate epoxide-resin glue under the setting-out in the space between separator layer and pile.
Because traditional building field will set the cofferdam isolated water earlier to the reinforcement means of water king-pile shaft, and carries out back cover with concrete, and then extract the water in the casing out, could carry out repairing and reinforcement to the pile body and handle.Than traditional method, the utility model just seem more the saving of labor, save time, save money, also low relatively on operation difficulty degree, the corresponding reduction of security risk.
A kind of slider that is used to add solid water king-pile post, described separator layer is prefabricated by fibrous composite, and separator layer invests pile top layer under water.Described fibrous composite is the tough measuring fiber composite material of fragrant glass under water.Described separator layer is looped around under water around the pile.The tough cloth of virtue glass is the high-performance fiber cloth that is formed by E glass fiber (E-glass) and aramid fiber (Kevlar) braiding.
The intensity height: it is good that layer of glass aramid fiber cloth tensile strength is equivalent to 3mm steel plate ductility: elongation per unit length 〉=2.5%, the good durable crashworthiness of shock resistance: exposed not wearing out do not corroded in 50 years, and anti-collision and wash away with carbon cloth and compare elongation per unit length greater than carbon fiber, so the design tension strain greater than carbon fiber thickness greater than carbon fiber, the not enough anti-seismic performance that has remedied modulus of elasticity is better than the carbon fiber glass fiber and fragrant fiber synthetic fibre fiber is isolator, and corrosion-resistant, be applicable to the engineering item of this generic request.
Such scheme is done further refinement, and the tough cloth of fragrant glass is the high-performance fiber cloth that is formed by special glass fibre and aramid fiber braiding.The extension property of glass aramid fiber cloth is better than other cloth, can resist lateral impact.Its coefficient of thermal expansion and modulus of elasticity and steel concrete are approaching, can not produce chemical attack, high temperature resistant and working year limit for length.In light weight, the construction weight increase of construction back is quite few.
Products characteristics: 1, intensity height: the tough cloth tensile strength of one deck virtue glass is equivalent to the 3MM steel plate, same one deck fibrous material of pasting, under identical distortion, the design pulling force that the tough cloth composite fibre of fragrant glass provides is 1.3 times of carbon cloth, and ultimate tension is 1.9 times of carbon cloth.2, non-conductive more durable: the tough cloth composite fibre of fragrant glass is an isolator, can not produce electrochemical corrosion.High temperature resistant, anti-low temperature.Its accelerated aging test result shows: under normal environment (not having ultraviolet direct projection), and its working life at least 50 years (burn into is not aging).3, superior permeability: but the easy construction reduction of erection time.4, ductility is good: the elongation per unit length of the tough cloth composite fibre of fragrant glass is between 2%--4%, and is more much bigger than the elongation per unit length (1.4%--1.7%) of carbon fiber.Not only elongation per unit length is big for the tough cloth composite fibre of virtue glass, and can resist lateral impact.With parcel bridge pier post and crossbeam, not only promoted supporting capacity, and facts have proved the position that is often broken before having protected by passing ships.5, good with concrete deformation harmony: the coefficient of thermal expansion of the tough cloth composite fibre of fragrant glass and modulus of elasticity are all approaching with steel concrete, coordinate as outer subsides material and the bridge concrete malformation that difference variation is bigger in the open air.Experimental results show that: the flexural member that the tough cloth composite fibre of fragrant glass is reinforced is plastic failure.6, execution conditions require low: easy construction, concrete base layer is required low, on-the-spot volume, bundle, curved, press the tough cloth of fragrant glass all can not decrease the folding fiber.Can not influence normal traffic circulation on the bridge in the work progress.
