The ground of the factory floor is treated with empty drums.
Third, the empty drum treatment after the concrete has been poured
For the existing empty drum, it is recommended to use Tianjin Zhengxiang Technology Co., Ltd. AB-1 grouting resin grouting repair treatment. Fill the empty drum position to ensure the integrity and durability of the building and meet the normal use requirements.
Zhengxiang AB-1 grouting resin is an empty drum special glue, which can be grouted for various conditions such as mortar, concrete, brick hollow and gap.

3. Construction steps
(1) Preparation before construction
Confirm the empty part that needs to be treated.
The drum position is drilled, the surface is cleaned, and the slurry is buried.
(2) Chemical grouting
Grouting is carried out after the grouting nozzle is installed: the grouting pressure and the grouting amount are determined according to the specific conditions of the hollow drum.
After filling the resin, pour it into the container of the grouting machine.
The grout resin was poured into the empty drum position with a high pressure grouting machine, which proved that the filling was full and the valve was closed. When grouting, it is necessary to prevent the grouting liquid from overflowing from other holes, resulting in waste. Confirm that the grouting is completed and remove the implement.
The resin was initially coagulated after 48 hours; it can be used normally after 7 days of dry curing.
4. Grout quality inspection method: tap detection. Core inspection.
5. Recommendations:
Due to cracks, defects and secondary repairs in the existing floor, it is recommended to repair it in the following ways:
The floor that has been repaired, the defect, the loose, the warped position, it is recommended to remove the whole body, and repair the Zhengxiang Z59 reinforced interface agent.
In the dense place where the ground crack is present, it is recommended to remove the whole body and repair it after painting the Zhengxiang Z59 reinforced interface agent.
For independent cracks, crack sealing paste or automatic low pressure grouting technology can be used for treatment.
6. Grout quality assurance:
The grout resin used in the field meets the technical performance indicators. The hollow part of the grouting treatment will no longer appear empty, ensuring the integrity and durability of the concrete.
The screed concrete hollow drum has become a common accident in the quality of the project. In the early stage, measures were taken to prevent and control. It is especially important to find an effective treatment method in the later stage. Effective preventive measures and repair methods can better harmonize the relationship between the construction unit and the construction enterprise, and also help the construction unit to solve the problem more economically.
The ground of the factory floor is treated with empty drums.
