【摘要】：北京新机场施工期,人为扰动地表强烈,若不采取防治措施可能造成较为严重的水土流失,尤其是对生态破坏和雨洪资源的影响突出。通过生态恢复分析和降雨径流、雨水利用计算,探讨了机场工程生态修复和雨水利用技术。生态恢复及雨水利用技术主要包括:1)施工前采取表土剥离,加以保护利用;重建地表水系;恢复耕地;恢复植被,重建植被生态系统;做好施工期临时防护措施,加强施工管理;提高工程区域林草覆盖率及生态景观,修复生态;2)收集降水,调蓄地表径流,雨水回用。通过布设调蓄水池、排水明渠、地埋式储水模块、渗透铺装、下凹式绿地、回用设施等收集降水,调蓄地表径流,使雨水主要用于绿地浇洒、道路洒水、水面景观用水、冲厕等,达到充分利用雨水资源,减少外排流量,节约用水的目的。
[Abstract]:During the construction of the new airport in Beijing, the artificial disturbance to the surface of the earth is strong. If no preventive measures are taken, it may cause more serious soil erosion, especially the impact on ecological damage and rain and flood resources. Through ecological restoration analysis and rainfall runoff, Rain Water made use of the calculation to discuss the ecological restoration of the airport project and the techniques of Rain Water utilization. The ecological restoration and Rain Water utilization techniques mainly include: 1) to take the topsoil stripping before construction, to protect and utilize; to rebuild the surface water system; to restore the cultivated land; to restore the vegetation, Rebuild vegetation ecosystem; do a good job of temporary protection measures during construction period, strengthen construction management; increase forest and grass coverage and ecological landscape in engineering areas, restore ecological area 2) collect precipitation, regulate surface runoff, and use Rain Water. Open drainage channels, buried water storage modules, infiltration paving, concave green space, recycling facilities, etc., to collect precipitation and to regulate surface runoff, so that Rain Water is mainly used for green land sprinkling, road sprinkling, water surface landscape water use, flushing, etc. To make full use of Rain Water resources, reduce discharge flow, water conservation purposes.
