摘要
随着对工程建设和环保要求的提高,对防渗墙的防渗性能要求越来越高。为防治土壤、地下水的污染及渗透变形提供一种新方法,本文介绍了日本研发的环保型生态粘土防渗墙(EC防渗墙)新工法。EC防渗墙具有止水性好、耐久性好、易施工、不排土和环保等优点,在环保、水利等工程中具有很好的应用前景。现场施工实践表明,该工法能在软土、密实砂砾石的潜水、承压含水地层中形成等厚式、柱列式EC防渗墙体,深度可达35m,墙体渗透系数达10-10m/s量级,具有很好的隔渗效果。
With the development of urbanization and the requirement of environmental protection, it is necessary to develop new sequester seepage wall method to prevent the soil and water pollution problems. A new Eco-Clay Wall method, which is developed by Raito Kogyo Co. Ltd. , Japan, is introduced. It has excellent sequester seepage effect, good service durability and environment-friendly due to the wall constructed by natural clay material and no dispose soil. The engineering practice shows that the impervious wall can be constructed in the soft and sand gravel stratum, and the wall depth reach 35m. The coefficient of permeability of the wall is about 10^-10m/s, which can be considered as an impermeable material.
