Embodiment Construction
[0024] Next, the present invention will be further described. It should be noted that, on the premise of no conflict, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments.
[0025] A waterproof refurbishment process for outdoor stadium stands, including step 1, base treatment: including a1, removing the base debris and seat nails on the top surface of the original stands, wherein the roots of the nails are lower than the ground and treated with antirust; b1, stair steps Anti-slip removal;
[0026] Step 2. Ground base grinding: Use grinding tools to perform 2-4 comprehensive grinding on the base. The compressive strength of the ground base concrete after grinding is greater than 25MPa, and the drop is not greater than 3mm when measured with a 2m ruler; the facade grinding should be meticulous, pay attention to grinding In place, no dead ends are left, and the grinding dust is cleaned up in time.

Abstract
The invention provides a waterproof renovation process for an outdoor stadium stand. The waterproof renovation process comprises the steps of base layer treatment, base layer polishing, base layer repairing and base layer full-surface coating of high-permeability waterproof primer. The construction steps of the high-permeability waterproof primer comprise the steps that a3, high-performance waterproof polyester cloth is pasted to cracks, hollowing and repaired parts through waterproof polyurea primer, and the polyester cloth is compacted and flattened; b3, primer coating is conducted; and c3, primer polishing is conducted. Elastic polyurea middle-layer paint is scraped in batches, the elastic polyurea middle-layer paint is polished and cleaned up after being dried every other day, and quartz sand is added into the elastic polyurea middle-layer paint. Elastic weather-proof finish paint is subjected to roller coating till a new stand base face is formed after drying, the roller coating frequency of the elastic weather-proof finish paint is not smaller than two times, and the thickness of the elastic weather-proof finish paint is not smaller than 0.15mm. The problems that after the stand is renovated, poor adhesion and abrasion and weather resistance are likely to happen to a waterproof layer can be solved, waterproofness is good, the construction efficiency is high, and the service life is long.
Description
technical field [0001] The invention relates to the technical field of building construction methods, in particular to a waterproof renovation process for stands of outdoor stadiums. Background technique [0002] At present, the surface layer of the stands of many open-air main stadiums is poor due to aging due to aging, which cannot meet the requirements of large-scale sports events. For example, the Huanglong Stadium, because the original base layer is concrete, even some areas of the upper stands are covered by ceilings. The strength of the original base surface is well maintained, and the old coating is irregular and partially peeled off, but there is no obvious water leakage. The upper stand is coated with a thin layer of old coating, which needs to be polished. The lower stand is an open-air area, the strength of the original base surface is worse than that of the upper stand, and there are more cracks in the whole. There is no old coating in some areas, and elastic c...
