Regional suspended seepage controlling wall structure with variable permeability coefficient and construction method thereof
The invention relates to a regional suspended seepage controlling wall structure with variable permeability coefficient and a construction method thereof, and aims to reduce the hydraulic gradient onthe end part of a seepage controlling wall, avoid the situation of seepage failure inside a soil body and ensure long-term safe running of the seepage controlling wall on the premise of meeting the overall seepage controlling functional requirement. According to the technical scheme, the regional suspended seepage controlling wall structure with variable permeability coefficient is characterized in that the seepage controlling wall is arranged in a deep pervious foundation, and consists of a hydraulic gradient retarding segment, an overlapping segment and a seepage controlling segment from bottom to top in sequence; and the permeability coefficient of the hydraulic gradient retarding segment is controlled to be about one tenth of the natural permeability coefficient of the foundation. Theregional suspended seepage controlling wall structure is suitable for seepage controlling and water retaining engineering with a base permeation soil layer through the suspended seepage controlling wall.
本发明涉及一种分区变渗透系数悬挂式防渗墙结构及其施工方法。本发明的目的是提供一种分区变渗透系数悬挂式防渗墙结构及其施工方法，以在满足总体防渗功能要求的前提下，降低防渗墙端部的水力梯度，避免土体内部出现渗透破坏的情况，保障防渗墙长期安全运行。本发明的技术方案是：一种分区变渗透系数悬挂式防渗墙结构，其特征在于：该防渗墙设置于深厚透水地基内，防渗墙由下而上依次分为水力梯度缓解段、搭接段和防渗控制段；所述水力梯度缓解段渗透系数控制在地基天然渗透系数的1/10左右。本发明适用于基础透水土层深厚，采用悬挂式防渗墙进行防渗的挡水工程。
