雨水收集垂直式渗透系统技术

The Vertical Infiltration System Applied to Rainwater Harvesting

针对城市内涝、地下水枯竭等问题,介绍了一种雨水收集垂直式渗透系统技术,对该技术整体结构及工艺流程进行了说明,阐述了其主要施工技术措施,同时,提出了水质处理措施。该系统利用垂直式雨水渗透管跨过地基持力层,将净化后的雨水直接导入地下含砂层,解决了雨水下渗与地基变形的矛盾。该系统对雨水进行有效的处理利用,为海绵城市建造提供了一种有效途径。

To deal with the problems such as urban waterlogging, groundwater depletion, a vertical infiltration system for rainwater harvesting is introduced in this paper. The main structure and processes of this technique are explained, the main construction technology measures are expounded, and the measures of water quality treatment are put forward. In this system, the vertical rainwater permeation pipe cross the foundation bearing stratum can directly introduce the purified rainwater into the the underground sand layer, which solves the contradiction between the rainwater infiltration and the foundation deformation. The system is effective in treatment and recycling of the rainwater and provides a powerful approach to realize sponge city.
