渗井技术在衡大高速公路的应用效果

渗井技术在水文地质条件满足渗透排水要求的平原微丘下穿式被交道路中值得推广,并在其他适用的情况下,经过改进也可使用且得到良好的效果.分析了我国高速公路目前的排水系统及路基高度过高导致建设成本居高不下的现状.通过对渗井系统设计方案及各方案适用范围的阐述、在渗井系统施工过程中值得注意的关键性技术指标的明确以及渗井系统已经取得的排水效果与各方面效益,表明其对于高速公路低路基以及排水问题解决的关键优势,并提出渗井技术除在华北平原高速公路建设中具有示范效应外,对于城市排水系统的建设也具有推广的可行性.

Application of the Seepage Wells Technology in the Hengda Highway

The seepage wells technology has been widely used in the hydrogeological conditions plain. It can also be used to have good results while improving in other applicable cases. This paper analyzes the current situation of highway drainage system and the high roadbed leads to high construction costs in our country. The seepage wells technology has produced good effects in drainage. The seepage wells technology has pivotal advantages in solving the problem of the low roadbed and the drainage in highways by expounding the suitable conditions of different drainage system designs,clearing the pivotal technical indicators of the seepage wells technology. The seepage wells technology has not only demonstrated the effect in north China plain but also showed promise in city drainage system.
