Description
Technical Field
The invention relates to the technical field of building leakage treatment, in particular to a leakage treatment method for a concrete honeycomb pitted surface.
Background
The problem of wall surface water leakage generally exists in the building engineering. The water seepage of the indoor wall surface of a light person and the falling of a plastering layer of the indoor wall surface of a heavy person cause the influence on the use function. The cause of the wall body leakage is complex, and the wall body leakage involves a plurality of links such as design, materials, construction, use and the like.
The problem of honeycomb pitted surface of the wall surface of a concrete structure is various, and the problem of honeycomb pitted surface can be caused by construction modes such as non-compaction or leakage vibration, insufficient vibration time and improper blanking due to the fact that concrete bone slurry is not uniformly dispersed, or concrete is not subjected to layered blanking, and upper-layer concrete is continuously poured into the wall root part without slight intermission. The concrete is too loose to resist the internal water pressure, so that leakage water can gush out from the pressure weak points and can carry calcium ions out of the concrete, and the service life of the concrete structure is greatly changed.
In order to solve the phenomenon, the conventional scheme adopted in the industry is to apply mortar on the surface or pour concrete and then carry out cement grouting treatment, only solve the problem that the hollowing of the honeycomb does not solve the main reason of water seepage of the honeycomb, so that secondary maintenance is caused, the cost is too high, huge economic loss is caused by the construction party or the owner, and the service life of the structure is influenced to a great extent. How to solve the problems of honeycomb pitted surface and fine cracks in the structure on the premise of not increasing construction period cost and reducing secondary maintenance rate is the problem to be solved by the application.
Disclosure of Invention
In order to overcome the defects, the invention aims to provide a method for treating the seepage of the pitted surface of the soil honeycomb, which cuts off a water inlet channel with a deep opening aiming at a concrete wall with seepage of the pitted surface of the honeycomb and solves the problem of honeycomb seepage.
In order to achieve the above purposes, the invention adopts the technical scheme that: a leakage treatment method for a concrete honeycomb pitted surface is characterized by comprising the following steps: the method comprises the following steps of 1, treating a base layer, and removing scum, dust and oil stains on the surface of concrete; step 2, taking holes for water diversion, finding out leakage parts, chiseling drainage holes in the leakage parts, and embedding water stop valves in the drainage holes for drainage of the leakage parts; step 3, chiseling the honeycomb position and sealing and repairing for the first time, chiseling a groove at the honeycomb position, and filling the groove with water leakage-free materials until no leakage occurs; step 4, wall body pretreatment, namely removing a decorative surface and a plastering layer on the surface of the wall body, polishing residues, then performing chiseling treatment, and cleaning sundries generated by chiseling; step 5, coating an interface agent on the wall, and circularly spraying water-based liquid and an anti-permeability agent on the wall to improve the anti-permeability coefficient of the wall; step 6, grouting the honeycomb position, namely, adopting a quincunx pinhole grouting method again for the honeycomb position to pour an acrylate grouting leakage-stopping material for stopping leakage; and 7, painting a waterproof layer, and performing waterproof painting of a surface layer on the wall.

The actual width of the additional layer is determined according to the actual width of the field, but the additional layer needs to be expanded on the original basis to better resist water pressure.
Further, the grooves in the step 3 are dug in a V shape, and the depth of the dug grooves is 5-8 cm. And a loose layer of the honeycomb is chiseled off, so that the loose area is prevented from being squeezed and cracked after grouting.
