Abstract
The invention discloses a kind of fast repairing method of ship lock concrete puzzle joint damage, it comprises the following steps：（1）Roughness polishing is carried out to puzzle joint edge using sander；（2）Puzzle joint is cleared up using oxygen, acetylene spray gun, dried, it is ensured that drying of the puzzle joint surface without attachment and puzzle joint surface；（3）Composite is mixed and stirred, repaired by hand is carried out to puzzle joint using composite using batch grey knife and scuppit immediately.The inventive method is repaired to lift wall puzzle joint, short time limit, and repairing effect is good, the rapid hardening in 25 minutes, ship is allowed normally to open the navigation or air flight in the interval of daily construction 8 hours, continuous construction 4 days, the whole patch works for completing puzzle joint in 32 hours altogether, reduce ship lock suspending time, full institute is avoided because the lockage fee collecting loss caused by maintenance of suspending is accumulative more than 450,000 yuan, then after heavily loaded ship collision, not situations such as there is not material stripping, deform, lift wall stability is kept well, and repairing effect is notable.
Description
Technical field
Face structure crossing over river field of engineering technology the invention belongs to water transport traffic, and in particular to a kind of ship lock concrete puzzle joint damage
Fast repairing method.
Technical background
Lock chamber wall be ship lock constitute important component, according at the management of navigational affairs of Jinghang Canal Northern Section in Jiangsu Province northern Suzhou not
Count completely, lift wall concrete puzzle joint generally existing among the 10 road ship lock of step 28 in place entirely, by measuring and calculating, per pass lock chamber
There is the ratio about 30%-40% that area accounts for lift wall entire area in wall puzzle joint, because lift wall is often subject to the firm of heavily loaded ship
Property collision, had a strong impact on boat lock safety.
The mode of water transport project processing lock chamber wall crack is generally digging up and filling in and grout filling.Digging up and filling in can destroy lock
The faying face of the overall structure of room wall, new backfill position and original lift wall is likely to become the new vulnerable area of lift wall.Using
During grouting treatment crack, slurries will have enough mobility, to keep into slurry effect.But the lock chamber wall concrete puzzle joint scale of construction compared with
Small, its length only has 0.6-1m, and wide about 3-5cm, depth not more than 6cm, the method is simultaneously improper.
At present, repaired using epoxy resin fracture, because crack is also changing with loads change, and
Cold snap easily bursts, and epoxy resin was easier to burst after 1 year, it is contemplated that the sustainability of this kind of method, and it repairs effect
Fruit is general.
The content of the invention
The purpose of the present invention is：A kind of fast repairing method of ship lock concrete puzzle joint damage is provided, this method is quickly repaired, work
Phase is short, and repairing effect is good.
The technical solution adopted for the present invention to solve the technical problems is the fast repairing method of ship lock concrete puzzle joint damage
Comprise the following steps：
（1）Roughness polishing is carried out to puzzle joint edge using sander；
（2）Puzzle joint is cleared up using oxygen, acetylene spray gun, dried, it is ensured that puzzle joint surface is without attachment and puzzle joint surface
Dry；
（3）Composite is mixed and stirred, repaired by hand is carried out to puzzle joint using composite using batch grey knife and scuppit immediately.
Wherein, composite is mixed by crack repairing glue, rubble, diluent, and its mass ratio is crack repairing glue：It is broken
Stone (3-5mm):Diluent=1.5：1.1：0.2, described crack repairing glue is DG-TPG repair sheets, and described diluent is two
Toluene class diluent.
Wherein, described composite material strength reaches 25.9MP, and its micro- varicosity product is no more than 6%, and tensile strength exceeds commodity
20-30 percentage points of concrete.
It is an advantage of the invention that：
1st, composite material strength reaches 25.9MP, and its micro- varicosity product is no more than 6%, and tensile strength is individual beyond commerical ready-mixed concrete 20-30
Percentage point, the rapid hardening in 25 minutes.
2nd, in practical operation, because the characteristics of composite rapid hardening, allowing ship in the interval of daily construction 8 hours
Normal navigation, continuous construction 4 days, the whole patch works for completing puzzle joint in 32 hours altogether reduce ship lock suspending time,
It can effectively be reduced through measuring and calculating and have ship lock non-faulting suspending time at the management of navigational affairs of northern Suzhou under its command 448 hours, accumulate currency amount
More than 10,450,000 tons, it is to avoid lockage fee collecting loss of the full place caused by maintenance of suspending is accumulative more than 7,000,000 yuan, uses this side
Method carries out the great social and economic benefit of repairing to lock chamber wall concrete puzzle joint.
3rd, than conventional repair method, this kind of maximum advantage of method for repairing and mending is its " fast ", by heavily loaded ship
, there is not situations such as material is peeled off, deformed, lift wall stability is kept well, repairing effect is notable in oceangoing ship collision rift.
