Abstract
The invention discloses a method for leakage water plugging, strengthening and repairing against a concrete crack. The method comprises a step a of drilling appropriate amount of plugging pulp injection inclined holes in a back face for the concrete crack leakage water, wherein the inclined holes extend to an upstream face of the concrete crack and reach the bottom of the concrete crack; a step b of installing an appropriate amount of pulp seats on an opening of the back face of the concrete crack and sealing the rest part of the opening; a step c of sealing openings of the pulp seats and injecting plugging agents from the plugging pulp injection inclined holes to plug the leakage; a step d of drilling appropriate amount of reinforcing slurry pulp injection inclined holes in the back face when the injection of the plugging agents is finished; and a step e of opening the seals of the pulp seats and injecting the reinforcing slurry from the positions of the pulp seats or the reinforcing slurry pulp injection inclined holes to complete the plugging and the reinforcement of the concrete crack. The method is simple and reasonable in step, the plugging and reinforcement are combined well, and the phenomenon of repeated leakage is avoided by the mode.
Description
Technical field
The present invention relates to recovery technique field, crack, particularly relate to a kind of distress in concrete infiltration water collision reinforcement and repair method.
Background technology
Distress in concrete is the physical arrangement change produced due to the effect of concrete structure internal and external factor, and crack is the main cause that concrete structure supporting capacity, durability and water proofing property reduce.
Part concrete structure plays dash effect in residing environment, when the through back side of distress in concrete and upstream face, will produce serious percolating water situation, at some Code in Hazardous Special Locations, likely can cause larger engineering accident.
At present, reparation for percolating water distress in concrete mainly adopts slip casting restorative procedure, but current slip casting restorative procedure mainly lays particular emphasis on leak stopping, because multiple leakage easily appears in the crack that the reasons such as alternation of wetting and drying are original after leakage plugging, its basic reason is that leakage plugging and crack reinforce and fails well to combine.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of distress in concrete infiltration water collision reinforcement and repair method, and simple and reasonable steps, combines leak stopping with reinforcing, avoids occurring multiple leakage phenomenon.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of distress in concrete infiltration water collision reinforcement and repair method, comprise following concrete steps:
A, for distress in concrete percolating water, back side bores the leak stopping slip casting inclined hole of right quantity, described leak stopping slip casting inclined hole extends to distress in concrete upstream face, arrives bottom distress in concrete;
B, the slurry seat of right quantity is installed on the opening of distress in concrete back side, then opening remainder is sealed;
C, the sealing of seat mouth will be starched, then inject sealing agent shutoff seepage from leak stopping slip casting inclined hole;
D, after sealing agent has been injected, back side bores the reinforcing slurries slip casting inclined hole of right quantity;
E, open slurry setting mouth, by from slurry seat or reinforce slurries slip casting inclined hole place inject reinforce slurries, complete distress in concrete leak stopping reinforce.
In a preferred embodiment of the present invention, in step b, fracture carries out sealing material therefor is epoxy mortar class joint seal material.
In a preferred embodiment of the present invention, described sealing agent adopts polyurethane grouting material.
In a preferred embodiment of the present invention, described reinforcing slurries adopt the hydrophilic epoxy resin grouting agent of high osmosis.
In a preferred embodiment of the present invention, the bottom reinforcing slurries slip casting inclined hole in steps d arrives the medium position of crack depth of concrete.
The present invention has following beneficial effect:
1, crack openings is completely closed, and sealing agent injects while water blockoff also can the air of pressure fissure inside, is unlikely to fill whole crack, to ensure the injection of epoxy resin slurries;
2, the injection of epoxy resin slurries can play reinforcement effect by fracture, ensures that the overall performance of concrete structure is good;
3, distress in concrete infiltration water collision reinforcement and repair method of the present invention, simple and reasonable steps, well combines leak stopping with reinforcing, avoids occurring multiple leakage phenomenon.
