Description
Technical field
The present invention relates to a kind of concrete slab horizontal construction joint faulting of slab ends repair mode.It is applicable to concrete slab
The similar engineerings such as face-plate of rockfill dam horizontal construction joint faulting of slab ends repair process.
Background technology
In CFRD engineering, because the slab joint that construction needs or other reasons is formed is for executing
Work is stitched, and construction joint is divided into again horizontal construction joint and vertical lap seam etc. according to its function.Generally, panel water
Flat construction joint with at the plate thickness 1/2 at seam as boundary, seam face, top is perpendicular to panel surface, seam face, bottom
Joint form in horizontal plane.
In recent years, along with the appearance of the heavy rolling apparatus of modernization, CFRD builds height of dam degree not
Disconnected increase, water cloth a strip of land between hills concrete slab engineering of maximum height of dam 233m is completed the most in the world, maximum height of dam
The monkey rock face dam engineering of 223.5m is built.For the CFRD of meizoseismal area,
Under seismic dynamic loading effect, easily cause the faulting of slab ends of panel-level construction joint, certain model at horizontal construction joint
Enclose concrete slab produce extruding destroy, bar bending or the phenomenon such as cut off, have a strong impact on the antiseepage merit of panel
Can, jeopardize the safe operation of dam.
Summary of the invention
The technical problem to be solved in the present invention is: for the problem of above-mentioned existence, it is provided that a kind of concrete slab
Horizontal construction joint faulting of slab ends repair mode, the safety and reliability run with enhancement engineering.
The technical solution adopted in the present invention is: a kind of concrete slab horizontal construction joint faulting of slab ends repair mode,
It is characterized in that step is as follows:
1, the damaged scope of horizontal construction joint periphery concrete slab is determined；
2, the concrete slab in the range of breakage is cut；
3, the cutting off and repairing of deformed bar, cuts off the deformed bar in the range of breakage, and uses replacement reinforcing bar
Replace the reinforcing bar cut off；
4, concrete slab backfill, uses concrete to backfill cutting region, is formed and connect divergence
Sewing on the repairing panel of portion's concrete slab and bottom concrete slab, the gradient of this repairing panel is 1:K,
K=L-0.05～L+0.05, former concrete slab along design slope, slope than for 1:L.
The gradient will be formed on the concrete slab on horizontal construction joint top after concrete chisel removal in the range of breakage
Upstream for 1:M is domatic, M=1～2, and it is 1:N that the concrete slab of horizontal construction joint bottom is formed the gradient
Downstream domatic, N=0.5～1.
The concave-convex surface fluctuating that described upstream and downstream are domatic.
Described replacement reinforcing bar welds with the reinforcing bar fissure of displacement not cut off in concrete slab；The replacement steel arranged up and down
Vertical bar connection is passed through between muscle.
The invention has the beneficial effects as follows: a, safety: this structure cuts horizontal construction joint periphery breakage concrete
Panel, cuts off deformed bar former in cutting region, and the replacement reinforcing bar of benefit prototype number is to recover original design joining
Muscle form, then with label identical with former panel, the concrete backfill of identical match ratio；Whole reparation thinking is patrolled
It is clear to collect, quality controllable, it can be ensured that the safety of engineering operation after reparation.B, reliability: this structure makes
Concrete slab after reparation and old panel effectively merge one, the bulk deformation adapting to dam body coordinates,
The effect of opposing external load, has stronger reliability.C, practicality: the method is simple to operate, construction is just
Profit, it is not necessary to special engineering equipment, has stronger practicality.

Detailed description of the invention
The present embodiment is a kind of concrete slab horizontal construction joint faulting of slab ends repair mode:
A, determine horizontal construction joint perimeter panel breakage scope: while panel-level construction joint faulting of slab ends, inevitable
Cause the breakage of horizontal construction joint 1 periphery certain limit inner concrete panel 2, therefore, stitch at panel-level
When faulting of slab ends is repaired, horizontal construction joint perimeter panel breakage scope need to be determined.The method that the present embodiment is taked is:
Width, occurrence and development according to 1 week edge crack of horizontal construction joint determine；For the district that cannot judge
Territory, uses the mode of boring and coring to verify the breakage of panel.Panel-level construction joint 1 time in this example
Portion's breakage scope takes d1=1～2m, and top breakage scope takes d2=2～3m.
B, cut the concrete slab in the range of breakage: after determining horizontal construction joint perimeter panel breakage scope,
This region inner concrete is cut.Construction for ease of later stage concrete is repaired, at horizontal construction joint after cutting
Domatic 22 gradients in upstream that the concrete slab 2 on top is formed are 1:M, generally M=1～2；Chisel
Domatic 21 gradients in downstream that after removing, concrete slab 2 in horizontal construction joint bottom is formed are 1:N, typically
In the case of N=0.5～1.Cut the upstream and downstream domatic 22,21 that concrete formed should try one's best concavo-convex fluctuating, with
It is easy to the combination of New-old concrete.
C, the cutting off and repairing of deformed bar: when cutting the concrete slab of breakage, deformed bar is cut off
After, mend with the replacement reinforcing bar fissure of displacement welding of prototype number, recover original design form of reinforcement；Again levels is substituted
Reinforcing bar Φ 16 vertical reinforcement is attached, and forms the bar-mat reinforcement closed.
D, concrete slab backfill: use label identical with old panel, identical match ratio concrete to cutting
Region backfills, and uses vibrating head to fill concrete vibratory compaction, is formed and connect horizontal construction joint top
The repairing panel 3 of concrete slab 2 and bottom concrete slab 2.Effective with former panel for guaranteeing repairing panel
Combine together, adapt to dam body bulk deformation coordinate, opposing external load effect without occurring splitting
Seam and breakage, gradient 1:K repairing panel 3 should strictly control, generally, when former concrete slab
2 along design slope, slope ratio during for 1:L, K=L-0.05～L+0.05.
