Concrete floor construction program requirements section a concrete foundation, a compacted fill, filling not use humus, silt, not including grass and roots and other debris, more than 10cm diameter should be broken using adobe. 2. Fill the design basis having sections layered filling compacted layer thickness> 0.3m, filling the width of not less than the design width. 3, fill compaction process Yunnan silicon pu, we should always keep moist clods, not dry pressing, rolling several times in order to achieve the required density of the date. 4. The degree of compaction requirements> 90% Yunnan 5mm silicon pu, the trajectory of less than 10mm. Second, the bottom of a limestone soil, lime soil with soil is loam, lime with long gray bag, using drinking water or groundwater. 2, the use of agricultural machinery and artificial mixing, mixing process detects moisture at any time, by repeatedly mixing uniform, smooth surface fine uniform, thick virtual control of 1.6-1.8. 3, rolling to the "first light after" principle, rolling several times 4-6 times 1-2 times after careful examination rolling surface roughness and height checking while shoveling up, can not wait after forming then supplement Yunnan 3mm silicon pu much money rolling solid flat surface, no peeling, waves, etc., compacted density to meet quality standards no wheel tracks so far. 4, the dust should be uniform mixing, color harmony, wheel track depth not greater than 5mm, shall not have surface dust, peeling, loose phenomenon. The degree of compaction of 95% thickness tolerance ± 10% elevation tolerance ± 2cm width of not less than the width of Guangzhou gifted tread design professional sports stadium silicon PU material suppliers courtside lines, long side boundary line of the basketball court, said end edges Yunnan silicon pu water advantage of the material, said the end of the short side of the boundary line. Midline from the sideline in a dotted line parallel to the end line called the center line; midline want to extend the sidelines each 0.15 m (15 cm). In the circle to the midpoint of the center line of a circle, with a radius of 1.8m, draw a circle called the circle. Restricted area three-point shot area is restricted by the court two arched out of the ground area. Restricted areas are marked on the playing court floor area, which consists of the end line, starting from the free throw line and two end lines (line drawing of the outer edge of the end line distance from the midpoint of three meters), and finally to the line defined by the outer edge of the line. In addition to the end line, these lines are part of the restricted zone. Inside the restricted area can be colored, but must be in the circle of the same color. The free-throw line, the penalty area to the line should be drawn parallel to each end line. Along a line from the inner end to its outer edge should be the most 5.80 m, a length of 3.60 m. It should fall on the midpoint of the line connecting the midpoint of the two ends of the imaginary line of the basketball court. Team bench area team bench area shall be marked in the scorer's table and the team into the same side of the outside. Each region consists of an extension of at least 2 meters long lines outward from the end line and another five meters away from the center line and at right angles to the sideline and defining at least 2 meters long lines. In the team bench area must have 14 seats for coaches, substitutes use. Any other person shall be at least two meters behind the team bench. Reasonable collision zone from the center of the ring floor to draw a semicircle 1.25 m, this area is known as a reasonable collision zone exemption.
