环保型EC隔渗墙新工法及其材料性质研究
摘要:随着都市化的进程,城市周边环境的复杂化,基坑数量的增多和深度的增大,基坑地下水控制变得日益重要。介绍日本研发的环保型EC墙隔渗帷幕新工法,包括EC墙工法概要、优点、应用领域和墙体材料性质。研究表明,该工法具有很好的隔水性能、耐久性好、易施工、不排土、环保等优点;墙体材料渗透系数小于10-8 m/s,止水性极好;在力学性质上,呈现出很好的韧性、不易产生裂缝、变形追随性强的特点。
Abstract:It is urgent to develop new sequester seepage wall method to prevent the soil and water pollution problems with the development of urbanization. A new Eco-Clay Wall method, which is developed by Raito Kogyo Co. Ltd., Japan, is introduced herein. The outlines of the new method, characteristics, application and wall material behaviors are described. Compared to the exiting sequester seepage wall methods, it has excellent sequester seepage effect, good service durability, environment-friendly due to the wall is constructed by natural clay material and no dispose soil. The coefficient of permeability of the wall is less than 10-8 m/s, which can be considered as an impermeable material. The wall shows large ductility, plastic deformation and no shear fracture failure .
