Detailed construction steps or procedures for making artificial lawns
(1) laying non-woven fabric along the length of the site, the arrangement direction must be 90 degrees with the arrangement direction of the lawn, and the bonding between the non-woven fabrics is firm.(2) according to the length and width of the lines of the drawings, judge the line of the stadium, and check the lines after the adhesion must be straight.(3) according to the specifications of the turf on the non-woven fabric, and between the turf needs to overlap 3-8mm.(4) the overlapping turf shall be uniformly cut with a cutter, and the joint shall be no more than 3mm.(5) the lower part of the cutting area shall be covered with seam fabric, and the joint surface shall be covered with adhesive.
Concrete construction process:(1) glue: it is required to use brush on its surface, even and uneven, and can not be repeatedly coated, or there will be foaming phenomenon, or even fall. The bottom cloth is coated with glue, and the thickness of the glue is strictly controlled. Attention should be paid to the speed of spreading. The glue should be applied to the two bonding surfaces respectively.(2) adhesion: according to the actual temperature, humidity, air pressure and other conditions of the actual impact, reasonable control drying time. In general, 10-30 minutes after the glue, the mortar reached eight or nine into dry, hand touch non stick is appropriate. When bonding requires a one-time alignment of cement. Must not be glued before moving the bonded object.(3) pressure: after bonding, remove the surface impurities, use a special rubber hammer from the adhesive to both sides of the hammer, so that the surface of the full exposure to dense, bonding more firmly.(4) curing: the curing time is usually three days, and the final strength is usually ten days. Therefore, during the curing period, it is necessary to pay close attention to the maintenance, avoid excessive exposure, immersion and movement, so as to achieve the best bonding state.(5) after bonding, clean the fragments of the lawn SOD before the sand and rubber particles are sprinkled.
Preparation before bonding:1, must be bonded to the bottom of the turf, non-woven fabrics, seams, cloth and so clean, and the surface dry, no moisture.2, the environmental temperature should be selected within 5 DEG C construction is appropriate, not construction in rainy and rainy weather, otherwise it will lead to a long time and even cause non stick adhesive phenomenon.
Quartz sand Paving Technology1, sand filling process: grass seedlings, using quartz sand for fixed grass seedlings, so that the grass seedlings do not lodge, sand filling to the remaining height of grass seedlings within 1 cm, on the surface of the seedlings to withdraw rubber particles, spread evenly. No sand grains with edges are allowed to be placed between the seedlings. Prevent an athlete from getting hurt.2, when spreading, use artificial glyph to broadcast.3, artificial grass field material is indeed installed after the completion of the laying of quartz sand and rubber particles.4, quartz sand laying, in order to integrate the idea of the application of the area into a square meter below the small area, and then the standard quantity of 25% quartz sand filled.5, quartz sand laying need to check whether the formation of sufficient and insufficient, need to be replenished.
Engineering survey and lofting1, inspection and acceptance of basic works. Clear the debris in the foundation works, if there is uneven place, should be repaired and leveled in time. Construction site shall be clean to ensure environmental cleanliness and construction quality. Follow the design plan, carry out measurement and lofting.2. Use steel tape measure to measure whether the surrounding facilities conform to the size of the sports field and make modifications if there is an inappropriate one.
