In the construction of basketball court, it is necessary to level the foundation first, then clean it up, then make floor glue, then lay silicon pu, and then mark it. After the base course is laid and hardened, drain to find the water accumulation point. After the experiment, according to the experimental results, proceed to the next process, and treat and level the water accumulation point according to the above process until there is no water accumulation in the floor glue. After the primer is completely hardened, use a grinder to grind the surface of the primer to meet the requirements of smoothness, and then spray anti-skid on the surface. Remove the cement and protruding parts, and then blow the whole site clean. Mark all kinds of lines in the site according to the drawings and design requirements. Treatment of some special places in the foundation of basketball court: the places where cracks appear in the foundation should be treated before the back cover of the foundation. The method is to clear the loose asphalt blocks at the grass-roots level, and then carry out paving construction. The thickness of each part should meet the design requirements, and the garbage at the joints should be cleaned up and then filled with mucilage.
