Wall body structure seepage treatment method

Abstract

The invention discloses a wall body structure seepage treatment method, which comprises the steps of: cleaning, which is implemented by cleaning calcium carbonate and other residues on the base surface of a wall body structure to expose a seepage part; chiseling, which is implemented by chiseling on the periphery of the seepage part by taking the seepage part as a center point; slurry injection hole drilling, which is implemented by finding out a water flow direction of the seepage part, and drilling a slurry injection hole at an inclined angle of 45 degrees according to the water flow direction of the seepage part; slurry injection nozzle installation, which is implemented by installing a slurry injection waterstop syringe needle in the slurry injection hole according to the depth of theslurry injection hole; chemical grouting, which is implemented by carrying out grouting by means of a grouting machine according to the width of the seepage part; interface agent brushing, which is implemented by stirring an interface agent evenly, evenly brushing the interface agent on a structure groove surface layer; plugging, which is implemented by plugging the chiseled seepage part with a plugging material; and surface layer waterproofing treatment, which is implemented by brushing a surface layer of the plugged seepage part by using a capillary crystalline waterproof coating. The wall body structure seepage treatment method effectively solves the wall body structure seepage problem, has good waterproof effect and is durable.

Description

technical field [0001] The invention relates to the technical field of building seepage treatment, in particular to a method for treating wall structure seepage. Background technique [0002] In construction projects, there is a common problem of water leakage on the wall. This is also a common quality problem in construction projects. If it is light, the indoor wall will seep, and if it is serious, it will cause the plaster layer on the indoor wall to fall off and affect the use function. The cause of wall leakage is more complicated, it involves design, material, construction, use and other links. [0003] (1) Material reasons: ① The quality of waterproof materials has declined, and the pass rate is generally low, especially for products produced by small factories. The quality of raw materials for waterproofing materials is also problematic. ② The quality of blocks, machine-made clay bricks, and cement cannot meet the requirements, and the strength is not enough, and t...

AI Technical Summary

Problems solved by technology

[0003] (1) Material reasons: ① The quality of waterproof materials has declined, and the pass rate is generally low, especially for products produced by small factories. The quality of raw materials for waterproof materials is also problematic

② The quality of blocks, machine-made clay bricks, and cement cannot meet the requirements, and the strength is not enough. The sand and gravel used for construction have a large mud content, exceeding the specification requirements

[0004] (2) Reasons for construction: ① The construction is not carried out according to the design requirements and construction specifications, the concrete mix ratio is not accurately grasped, and the water-cement ratio is too large, which affects the strength of the concrete wall

Poor vibrating, untimely maintenance, and premature removal of formwork during pouring will also cause honeycomb, pockmarked surface, holes, and cracks in the concrete wall.

② The quality of wall masonry is poor. Among the various common quality problems of brick masonry, the reasons affecting the leakage of the external wall are: the mix ratio of masonry mortar does not meet the design and specification requirements; %, there is no mortar in the vertical mortar joints (empty joints or blind joints), and internal passages are reserved for rainwater leakage; when the filling wall in the frame structure is built close to the bottom of the beam or the bottom of the slab, the inclined brick roof is built without stopping To the bottom of beams and slabs, later, as the masonry is compressed and deformed by the mortar joints, the wall will sink, and a gap will be formed between the oblique brickwork and the beams and slabs. When the outer wall is plastered or shaved, it will form a Cracks; the tension reinforcement between the frame column and the infill wall does not meet the modulus of the brick, and the bent steel bar is pressed into the brick layer during masonry, forming a large gap between the masonry and the column at a local location. prone to cracks

[0005] At present, the measure to solve the leakage of the building wall structure is to adopt the method of sealing, and seal the cracks on the wall with waterproof sealing materials, so as to prevent water from penetrating into the inside from the outside of the wall, but it can only solve the problem of wall leakage in a short time. Structural leakage problem, anti-leakage effect is not ideal
