Embodiment 1

[0023] This embodiment provides a construction method for repairing hollow micropores on wear-resistant emery floors, including the following steps:

[0024] ⑴Before construction, hit the empty drum on the site floor with a small hammer, make a comprehensive and detailed statistics, and clearly mark the empty drum on the drawing;

[0025] ⑵Selection and positioning of the glue injection space, according to the area marked on the drawing, the construction personnel will design and locate the drilling position of each hollow drum on site, use an electric drill to drill the selected position of the hollow drum, and bury the glue injection at the drilled hole mouth;

[0026] (3) Before using the high-pressure pump to inject glue, first conduct a permeability test on the drilled hole to make the drilled hole have good permeability and lay the foundation for smooth grouting;

[0027] ⑷In order to ensure that the grout does not flow out when the grouting is pressurized, the cracks o...

Abstract

The invention relates to a hollow and micropore repair construction method of a wear-resisting emery ground. Through the process of early-stage drilling and high-pressure pump glue injection, ground hollows are repaired. After emery wear-resisting ground micropore repairing is adopted, ground hollows are all eliminated, surface cracks are all sealed, from the ground coring experiment result, compressive strength can reach design strength, from impressions, surface cracks cannot be seen clearly by naked eyes, and the effect of the repaired ground is good.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for repairing hollow micropores of a wear-resistant corundum floor, and belongs to the technical field of building construction. Background technique [0002] With the rise of various emerging industries, the rapid development of the construction industry, and the increasing quality of people's lives and demands, the functional requirements for buildings are getting higher and higher, and the people's demand for the quality of buildings is also getting higher and higher. Among them Wear-resistant emery floor is also widely used in various public buildings, garages, factory floors, etc. In the construction of conventional construction projects, for public buildings, garages, workshops and other cast-in-place concrete floors with secondary concrete pouring, cracks and hollows in the leveling layer often seriously affect the use function and structural safety of the pro...
