Abstract
The invention discloses a kind of concrete-bridge repair technology, its drip irrigation device is to comprise the following steps：（1）Cut, cut to form pavement groove；（2）Through hole is drilled with the inwall of pavement groove, to resin by injection adhesive in through hole and is uniformly laid on the inwall of pavement groove；（3）Then to the mixture that new concrete and coal tar are filled in pavement groove；（4）Pat to form decorative pattern using cotton；（5）Toasted at 40 ~ 60 DEG C using dryer；（6）Brushing emulsion paint；Using above-mentioned technique to being repaired at bridge failure, the structural strength at bridge failure is significantly improved, extend the service life of bridge.
Description
Technical field
The present invention relates to bridge paving process, more particularly to a kind of concrete-bridge repair technology.
Background technology
Since concrete-bridge occurs from the seventies of 19th-century six, the experience development of more than 100 years, in bridge now
During beam is built, concrete-bridge has had been widely adopted, in Short/Medium Span Bridge, continuous bridge and Longspan Bridge is built
Have and widely apply.Steel can be saved using concrete-bridge, the Master Cost of bridge is reduced, compared with steel bridge, with more
Low maintenance costs, driving noise is small, and tensile strength is low, compression strength is big compared with high, rigidity.
In existing concrete-bridge, due to being influenceed by work progress, construction material, different outward appearances can be caused
Defect, largely effects on its aesthetic appearance of made concrete-bridge, more brings subsequent construction difficult and peace to large bridge construction
Full hidden danger, common open defect has pitted skin, honeycomb, dew muscle with larger area defect etc..
Smear that one pitted skin is floating using cement mortar for the less plane of area, then with 2: 3 ordinary cement: plain boiled water
The concrete grey of mud is smeared one time；For cellulor, using wire brush outwash, pressure flush of water is clean, then is smeared with 1: 2 cement mortar
It is flat；The honeycomb larger for area, then should all cut soft around concrete and prominent particle, expose hard coagulation
Native surface, concrete surface is cleaned down with wire brush, then clean with pressure flush of water；For dew muscle portion point, then extruding is full of dew
Muscle portion point is floating again, and when revealing muscle and being deeper, chisel goes weak concrete layer and prominent aggregate to use fine concrete after scrubbing clean
Tamp, and fully consolidate.
At present, application publication number is a kind of for bridge road for the Chinese patent of CN105906232A is disclosed in existing patent
Mending mortar, preparation method and the construction method mated formation are repaired in face, and carrying out cutting at road surface breakage forms pavement groove, is mating formation
Filling and repairing mortar in groove, using the mending mortar by the solidification of short period, can reach mechanical strength higher.
But, using the breakage on above-mentioned mending mortar filling bridge surface, after mortar to be repaired is solid, concrete-bridge
In mend compared with former bridge, there is color and luster inequality, the phenomenon that color differs.
The content of the invention
It is an object of the invention to provide a kind of concrete-bridge repair technology for still keeping uniform coloration after repairing.
Above-mentioned technical purpose of the invention technical scheme is that：
A kind of concrete-bridge repair technology, comprises the following steps：
(1) breakage on concrete-bridge surface is cut, cut and is cleared up, formed and to be repaired foursquare mated formation
Groove；
(2) through hole that the non-breakage of oriented bridge extends is drilled with the side wall of pavement groove, the length of through hole is the length of pavement groove
/ 2nd of degree, then to plugging filament carbon fibre in through hole and extending in pavement groove, continue to pouring resin in through hole
Adhesive, treats that resin adhesive substantially uniformity is laid on the inwall of pavement groove；
