| 人造草坪由3层材料组成。基础层是由夯实土层、碎石层和沥青或混凝土层组成。基础层要求坚实、不变形，表面光洁和不透水，即一般的混凝土场地。由于曲棍球场地面积大，施工时一定要处理好基础层，防止下陷。若铺混凝土层，混凝土固化后要切割出膨胀缝，防止热胀变形和裂缝。 The artificial lawn consists of three layers of materials. The foundation layer consists of compacted soil layer, gravel layer and asphalt or concrete layer. Foundation layer requires solid, non-deformable, smooth and impermeable surface, that is, general concrete site. Because of the large area of hockey field, we must deal with the foundation layer to prevent subsidence. If concrete layer is laid, expansion joints should be cut out after concrete solidification to prevent thermal expansion deformation and cracks. 基础层之上是一层缓冲层，通常为橡胶或泡沫塑料组成。橡胶弹性适中，厚度3~5mm。用泡沫塑料成本较低，但弹性差，厚度5~10mm，过厚草坪太软，而且易凹陷;过薄缺弹性，起不到缓冲作用。缓冲层要牢固地粘贴在基础层上，一般用白乳胶或万能胶粘贴。 Above the base layer is a buffer layer, usually composed of rubber or foam. The elasticity of rubber is moderate and the thickness is 3-5 mm. The cost of using foam plastics is low, but the elasticity is poor, the thickness is 5-10 mm, the lawn is too thick and soft, and it is easy to depression; too thin and lack of elasticity can not play a buffer role. The buffer layer shall be firmly pasted on the base layer, and generally pasted with white emulsion or universal glue. 第三层，也是表层，为草皮层。依制造的表面形状有绒毛草皮、圆环形卷曲状尼龙丝草皮、叶状聚丙烯纤维草皮、尼龙丝编制的透水草皮等。这一层也必须用乳胶粘在橡胶或泡沫塑料上。施工时必须全面涂胶，依次压紧贴牢，不能起皱折。 The third layer, also the surface layer, is the turf layer. According to the surface shape, there are wool turf, circular curly nylon silk turf, leaf polypropylene fiber turf, nylon silk pervious turf and so on. This layer must also be adhered to rubber or foam with latex. During construction, it is necessary to apply glue in an all-round way, press tightly and firmly in turn, so as not to wrinkle. 在国外，草皮层常见两种:1、草皮层叶状纤维较薄，仅1.2~1.5mm;2、草皮纤维较厚，20~24mm，其上用石英填充几乎到纤维顶部。 In foreign countries, there are two common types of turf: 1. Leaf fibers in the turf layer are thin, only 1.2-1.5 mm; 2. The turf fibers are thicker, 20-24 mm, on which quartz is filled almost to the top of the fibers. |
