生态停车场结构改良研究

Research on the Structure Improvement of Ecological Parking Lot

为有效解决生态停车场交付使用后一段时间就出现草皮空秃严重的问题,该研究系统地对生态停车场结构中的3类面层材料、5类结合层材料、5类基层材料作了对比。结果表明：当停车场结构的基础为素土夯实,基层采用150 mm厚三七灰土加100 mm厚C15素混凝土,结合层采用30 mm厚1∶3水泥砂浆时,面层采用200-300 mm厚自然石既能有效控制草皮空秃问题,停车场的结构稳定性也较好;当停车场结构的基础为素土夯实,第1基层采用150 mm厚三七灰土,第2基层材料改用200 mm厚级配砂石,结合层材料改用50mm厚1∶3泥砂混合时,面层材料采用60 mm厚嵌草砖或70 mm厚植草格的综合效果良好。

In order to effectively solve the problem that the turf empty bald seriously after ecological parking lot putted into service some time,the contrast test of 3 kinds of surface layer materials,5 kinds of bonding layer materials,5 kinds of base layer materials were studied systematically. The results showed that： when the foundation of the ecological parking lot for rammed earth,base layer material with 150 mm thickness 37 lime earth and 100 mm thickness C15 plain concrete,bonding layer material with 30 mm thickness 1∶ 3 cement mortar,the surface layer material is made of 200- 300 mm thickness natural stone can effectively control the turf empty bald problem,and the structure stability of the ecological parking lot is better; when the foundation of the ecological parking lot for rammed earth,the first base layer material with 150 mm thickness 37 lime earth,and the second base layer material to 200 mm thickness gradated sand-stone,bonding layer material to 50 mm thickness 1： 3 clay sand mixture,the comprehensive effect is good when the surface layer material with 60 mm thickness grass-brick-block or 70 mm thickness grass grid.
