Embodiment Construction
[0028] (1) Interface processing
[0029] Remove surface oil and loose parts of the structure to be reinforced. In order to facilitate the control of the thickness of the mortar layer, ash cakes are pre-made on the surface of the structure to be reinforced, and the distance between the ash cakes is not greater than 2m. Bind the steel strand mesh or steel mesh outside the structure to be reinforced according to the design requirements. In order to ensure a good combination of the structure interface and the interface agent, it is best to spray water on the structure to be reinforced 24 hours in advance to ensure that the surface of the structure to be reinforced is wet without clear water before spraying construction.
[0030] (2) Interface agent injection
[0031] Use an air hammer to manually mix the cement-based interface agent containing polyacrylate with water, connect the spray gun to the air compressor, and use the spray gun to spray the interface agent onto the base su...
