| 彩色透水地坪路面基层的要求 Requirements of color pervious floor pavement base 1、彩色透水地坪的厚度：从上可知因彩色透水混凝土强度的原因，大都应用于人行道、广场、停车场、园林小道、小区道路等场所。根据路面的不同应用面层厚度不同，对人行道、自行车道等轻荷重地面，一般透水混凝土厚度不低于8㎝；对停车场、广场等地面中荷重地面，透水混凝土厚度不低于10㎝。 1. Thickness of colour pervious floor: It can be seen from the above that the strength of colour pervious concrete is mostly used in pavements, squares, parking lots, garden paths, residential roads www.oudiya.net www.dingxinkeji.net www.futeqizhong.com www.baoyunzhiban.com www.xinxingjiancai.com.cn www.jinhuaronglian.comand other places. According to the different application of pavement, the thickness of permeable concrete is not less than 8 for light-load ground such as pavement and bicycle road, and not less than 10 for medium-load ground such as parking lot and square. 2、为确保路面体结构层具有足够的整体强度和透水性，表面层下需有透水基层和较好的保水性垫层。基层要求：在素土层夯实层上，配用的基层材料，应有适当的强度外，须有较好的透水性，采用级配沙砾或级配碎石等。采用级配碎石时，碎石的大粒径应小于0.7倍的基层厚度，且不超过50mm。垫层一般采用天然碎石，粒径小于10mm，俗称瓜子片，并铺有15cm~30cm厚度，铺设需均匀平整。 2. In order to ensure that the pavement structure layer has enough overall strength and water permeability, a permeable base and a better water-retaining cushion are needed under the surface layer. Base requirements: In the compacted layer of plain soil, the matched base material should have proper strength, good permeability, graded gravel or graded gravel, etc. When Graded Macadam is used, the large size of macadam should be less than 0.7 times the thickness of base course and not more than 50 mm. The cushion is usually made of natural gravel with a particle size less than 10 mm, commonly known as melon seed slices, and the thickness of the cushion is 15 cm to 30 cm. The cushion should be laid evenly and smoothly. |
