近年来,在鄱阳湖区堤防加固工程的堤基防渗处理工作中,深搅防渗墙技术得到了广泛的应用,同时也取得了很好成果。深搅防渗墙主要是利用特殊机械对固化剂进行深层搅拌,以使软土变成具有一定强度的柱状或壁状的加固体。工程中采用深搅防渗墙的主要目的在于改善软弱地基,同时加固地基以提高地基的承载能力。文章主要通过对鄱阳湖区堤防加固工程项目的分析,介绍深层搅拌防渗墙的施工原理、技术以及施工的方法。
In recent years, in the embankment seepage control work of the embankment reinforcement project in Poyang Lake District, the deep seepage-proof wall technology has been widely used, and also achieved good results. Deep infiltration impervious wall is mainly the use of special machinery for curing agent deep mixing, so that the soft soil into a certain strength of columnar or wall-like reinforcement. The main purpose of using the deep infiltration cutoff wall in the project is to improve the soft foundation while strengthening the foundation to improve the bearing capacity of the foundation. The article mainly analyzes the construction of embankment reinforcement project in Poyang Lake area and introduces the construction principle, technology and construction method of deep mixing cutoff wall.
