 Plastic venues, basketball court, soccer field, badminton, PVC sports flooring, silicon PU ground stadium building construction enterprises, with 

 A variety of large, medium and small venues or training venue construction. Over the years the company had a long cooperation relationship with more than 30 companies 

 . The accumulation of years of construction technology. The company has a unique set of practical construction techniques. More than 30 companies throughout the country have been a 

 Given recognition. And achieved good economic and social benefits. Have professional experience in construction team, years of performance and unique construction technology 

 Technique to our quality of service and quality has laid a solid foundation. Dozen high-quality plastic material and artificial turf, but also to participate in the plastic 

 Site design and construction of a number of construction experience, technology and first-class professional construction team, perennial active around the plastic, acrylic, elastic 

 Acrylic and artificial turf stadium on the ground, the construction of high quality plastic, artificial turf stadium, and provide good after-sales service. Shi 

 Engineering technology remains the leading domestic level, the Company made to the site can be comparable with foreign plastic venues. In recent years, the construction area throughout the country 

 Completed in recent years, indoor and outdoor various stadium, running track and artificial turf field construction of more than 1 million square meters, Major projects completed 

 The Department, through customer acceptance, and was rated as excellent works. With complete sets of equipment and spraying equipment, capable of performing a variety of complex conditions and other sports venues 

 Engineering design and construction; seven experienced, first-class technology and construction team, have a multiple site construction, we will adhere to the "true 

 Sincere service and social returns "business purposes, to ensure quality, customer satisfaction and timely completion of the construction tasks. 



 A foundation treatment, the new cement concrete foundation: 

 (1) Basic requirements: 

 Solid flat (flatness: 3m straightedge error is less than 3mm), there are some drainage slope (usually not more than 40/00 horizontal and vertical non- 

 Greater than 20/00, must ensure that the discharge), the intensity of the C25 strength of structural concrete standards, pouring water conservation at least seven days, overall curing raising of 

 Care of not less than 28 days (to ensure that the cement curing time, so that the white powder of the cement during the curing process to completely precipitate the underlying surface). New 

 Pouring cement foundation must cut a reasonable temperature expansion joints, in principle, not more than 6x10m a box cutting, if the segment is cast plates will 

 Seam to be the cutting temperature, cutting temperature joint requiring wide as 6 ~ 8mm, depth no less than 30mm, (to ensure that the basis of thermal expansion and contraction can focus on the change in temperature cracks 

 Technology, does not lead to the basis of other parts of cracking). 

 (2) The processing: (seam wear - pickling - primer - Caulking - leveling, patching) 

 a, grinding joints: the temperature sewing both sides of the face width of 40 ~ 50mm ground bevel deep 3mm (Figure (a) shows), so that the temperature sewing surface into the "V" 

 Type, (40 to 50 wide to improve the bonding of the sealant with the base surface area, to increase its adhesion, 3mm deep to ensure that the thickness of the sealant without taking up flexible 

 Layer, and ensure that the overall buffer, based on thermal expansion and contraction does not affect the silicon PU surface). 



 b, pickling: dilute hydrochloric acid with water and moist basis (to prevent infiltration of the base inside), a concentration of about 8% of the uniform dilute hydrochloric acid spill and wash 

 Brush the base surface, and then water rinse (usually wash twice), washing drying requirements of the primary color of the base surface of cement, white powder compounds and floating loose material. 

 Ring out the water in the pickling process to bits and do the logo mark. 

 C,-specific primer (TB-201) the principle of multi-channel roll coating surface at the base, after brushing the base surface to form a light film Primer: the base is dry enough 

 Date, must make up deficiencies in the coating to enough so far, (the role of the primer to penetrate the tiny holes into the foundation, cured after the blockage of groundwater gas and to 

 Solid base surface; to form a light film is to ensure that the basis of micro-holes completely blocked), should be avoided under the hot sun or the basis of high temperature (> 450C) 

 More appropriate for the construction painted the permeability of the end of the guarantee (no fog, rain weather in the morning or evening). Attention to trimming the repair of the surface of the base strength of 80 mesh, the dosage is reduced accordingly) Do not let the side above the base surface repaired, and if so to be playing after curing higher 

 To wear flat elastic layer construction. 

 2, the old cement concrete foundation: 

 (1) Basic requirements: 

 Firm, smooth, without sinking plate off the crack does not exceed 10mm wide, if not cutting a reasonable temperature seam, cutting must be in accordance with the new cement foundation requirements 

 The temperature seam. If the basis of wide cracks in sink or very uneven, broken too many phenomena such as the proposed re-use of asphalt concrete (> 40mm thick) or cement 

 Concrete (50mm thick) laying leveling basis. 

 (2) The basis of treatment: 

 The basic approach to the new cement concrete foundation. If the foundation cracks more than 2mm wide, widening the application of cutting machine for column 6 ~ 8mm, according to the new 

 Cement foundation requires grinding seam, caulk; if the width is less than 2mm, seam surface ground into the "V" font, thickness 50mm, depth 3mm, the direct use of fillers 

 Plastic multi-channel filled to. (Figure (3) show)
