Ober sports facilities in Suzhou Co., Ltd. is a professional sports venue construction, indoor and outdoor hard tennis courts, basketball courts, badminton courts, handball court, volleyball, hockey games, the stadium gates and other works of acrylic, acrylic elastomeric contracting, design, construction plastic runway, made of artificial turf acid, water-based silicone PU, pure PU, EPDM cast, kindergarten playground, golf and other types of court, following a simulated golf, golf greens, squash, swimming pool, adult and children's climbing wall design and construction projects. Construction base requirement for quality venues basis of the first pass, a good foundation to be successful start, the base surface with cement foundation, it should meet the following requirements: 1, the new cement poured sufficient curing time (many in 15 days). 2, the surface roughness, 3 m straightedge tolerance ≤3mm. 3, under the rough on the fine according to the design and construction, the chamber degrees to reach more than 95%, no cracks, indentation, and so on. 4, located around reasonable drains. In order to ensure smooth drainage, base surface to find the slope ≤5 ‰, and meet the design requirements. 5, not construction rainy day, avoid the sun or the temperature 10 ℃ in the case of small construction. 7, indoor venues should maintain good ventilation convection. Second, the main construction method, construction technology base surface treatment → fill hole buffer layer construction → Construction → strengthening layer construction → Construction → crossed the finish layer 2, the construction techniques of handling a 2.1 base) to clean work surface, then use Shimizu wet base surface, rinse with water. Observe the remaining traces of water on the base surface flatness and slope were tested, with a marker to draw water at the circle. Base surface should be free of white chalk dust matter and after washing and drying. 2) After the dry grass roots, for obvious protruding parts polished handle, and then fill the hole back construction. When the construction of the base surface requires strong, dry, clean, smooth, no oil and powder from the phenomenon.
