大广高速公路衡大段渗透井技术研究

Infiltration Well Technology for Hengshui to Daming Section of Daqing to Guangzhou Expressway

在大广高速公路衡大段设计中,针对平原地区高速公路通道积水问题,根据沿线气候、水文、土壤地质等特点,采用"边沟→集水井→沉淀井→渗透井(或蓄水井→小回灌井)"这一渗透排水系统,具有良好的经济、社会和环境效益。

In the design of Hengshui to Daming Section of Daqing to Guangzhou Expressway, in allusion to the channel hydrops problems of expressways in plain areas, according to the characteristics such as climate, hy- drology and soil geology along the expressway, this paper analyzes the infiltration drainage systems which is ＂side ditch, collector well, settling well, infiltration well＂. It has good economic, social and environmental benefits.
