Problems solved by technology

[0003] The present invention aims at the rough and simple ground repairing technology existing in the prior art, and does not fully consider the influence of external environmental factors that may occur in the process of repairing before, during and after the construction and the strength of the raw materials used is not good, thus causing the repaired ground to be easily damaged. The problem of crushing, shelling and damage, which greatly wastes manpower and material resources, provides an economical and practical repairing construction technology for concrete floors

Embodiment 1

[0026] Such as figure 1 As shown, a repair construction process for concrete floors, the steps are as follows:

[0027] The first step: select the concrete floor to be repaired, plan to remove the degraded surface layer, and remove the surface dust until a clean concrete base surface with defects is exposed;

[0028] The second step: clean the surface of the concrete base layer with water and keep it moist;

[0029] The third step: take the high-strength non-shrinkage grout into the container, add 10% of the total weight of water, mechanically stir for 2-3 minutes, stir evenly into a slurry, and use it for later use;

[0030] The fourth step: take the above-mentioned slurry and pour the defect on the surface of the concrete base layer to fill it smoothly. After the slurry is solidified, polish the concrete with protrusions on the surface to be smooth, and then take the above-mentioned slurry and pour a layer on the entire surface of the concrete base layer After compaction and levelin...

Embodiment 2

[0034] Such as figure 2 As shown, a repair construction process for concrete floors, the steps are as follows:

[0035] The first step: select the concrete floor to be repaired, plan to remove the degraded surface layer, and remove the surface dust until a clean concrete base surface with defects is exposed;

[0036] The second step: clean the surface of the concrete base layer with water and keep it moist;

[0037] The third step: take the high-strength non-shrinkage grout into the container, add 15% of the total weight of water, hand-stir it for more than 5 minutes, stir evenly to form a slurry, and set aside;

[0038] The fourth step: take the above-mentioned slurry and pour the defect on the surface of the concrete base layer to fill it smoothly. After the slurry is solidified, polish the concrete with protrusions on the surface to be smooth, and then take the above-mentioned slurry and pour a layer on the entire surface of the concrete base layer After compaction and leveling, t...

Embodiment 3

[0042] Such as image 3 As shown, a repair construction process for concrete floors, the steps are as follows:

[0043] The first step: select the concrete floor to be repaired, plan to remove the degraded surface layer, and remove the surface dust until a clean concrete base surface with defects is exposed;

[0044] The second step: clean the surface of the concrete base layer with water and keep it moist;

[0045] The third step: take the high-strength non-shrinkage grout into the container, add 12% of the total weight of water, stir by hand for 8 minutes, stir evenly to form a slurry, and set aside;

[0046] The fourth step: take the above-mentioned slurry and pour the defect on the surface of the concrete base layer to fill it smoothly. After the slurry is solidified, polish the concrete with protrusions on the surface to be smooth, and then take the above-mentioned slurry and pour a layer on the entire surface of the concrete base layer After compaction and leveling, the pouring...

Abstract

The invention relates to a ground repairing technology and discloses a construction process for repairing concrete ground. The construction process for repairing the concrete ground comprises the following steps of: selecting the concrete ground, planing a deterioration layer, removing dust, cleaning and moistening by the use of water, mixing a high-strength non-shrinkage grouting material and water which accounts for 10-15% of the total weight with stirring to obtain a slurry, pouring the slurry into ground defect positions to repair and smoothen the ground, flattening the ground after solidification, pouring the slurry onto the surface of the whole concrete substrate to form a layer of 0.3cm-3cm thick, naturally drying for 10-14 hours, covering the layer with a maintenance pad, watering, followed by wet curing for several days, and removing the maintenance pad to finish the construction process. According to the technical scheme provided by the invention, apart from the full consideration of concrete ground situation and the impact of external environment such as temperature, climate and the like during the construction process, the high-strength non-shrinkage grouting material with high strength and good viscosity is used such that the repaired ground has a high hardening strength and is not easy to crush and damage, and manpower and material resources are saved.

Description

Technical field [0001] The invention relates to a ground repair technology, in particular to an economical and practical repair construction technology for concrete ground. Background technique [0002] At present, the concrete floor, especially the concrete floor in the factory area, often has undesirable phenomena such as shelling, damage, etc. It usually needs to be repaired or re-excavated and poured, or a layer of asphalt is poured on the original ground, resulting in the ground is not smooth enough and the strength is not enough. It is not easy to clean. At the same time, the current concrete floor repair construction technology is rough and single, and the technical content is not high. On the one hand, the reason is that the strength of the repair material is not enough, and it is easy to shell and cracks, which affects the strength and bearing capacity of the repaired concrete floor. On the other hand, the reason is that the repair construction process of the concrete fl...
