LID技术在湿陷性黄土地区小区雨水控制中的设计探讨

Discussion on the design of LID technology in the control of rain water in the area of collapsible loess

基于低影响开发(LID)理念,对湿陷性黄土地区某建筑小区内的雨水控制进行规划设计,从雨水源头减少对市政排水管网的压力并降低城市内涝的几率。此建筑小区综合采用了多种低影响雨水控制技术措施,能很好地控制雨水,符合我国海绵城市建设的要求,并具有一定的经济、环境及社会效益。考虑到湿陷性黄土的土质问题,在设计中采取相应的技术措施。

Based on the concept of low impact development(LID),the collapsible controled loess area of rain in a residential district planning and design,from the source of water reduced the pressure of municipal drainage pipe network and reduced the risk of urban water-logging.The construction area of the comprehensive use of a variety of low water control technology measures,can control the rain wery well,in line with the requirements of the construction of China's sponge City,and had a certain economic,environmental and social benefits.Taking into account the soil of the collapsible loess,the corresponding technical measures were adopted in the design.
