橡胶层防渗在土石围堰中的应用

Application of Rubber Layer Seepage Control in Earth Rock Cofferdam

橡胶面板土石围堰是由土石筑堰而成的围堰,以橡胶面板防渗层代替黏土心墙防渗体的新型围堰。它利用橡胶的柔性、防渗透性、造价低和施工简单的特点,弥补了土石围堰施工工艺繁琐、容易受施工条件限制等问题。文中主要研究了橡胶面板土石围堰的结构设计和施工工艺,并对这种新型围堰进行了可行性分析,采用实验的方法对橡胶的耐久性进行分析,并进一步分析橡胶土石围堰的可行性。

The rubber panel earth rock cofferdam is a cofferdam formed by the earth rock dam, and a new type of cofferdam, which is replaced by the impermeable layer of the rubber slab, is a new type of the impervious wail of the core wall. It makes use of the characteristics of flexible rubber, anti permeability, low cost and simple construction, which make up the construction process of earth rock cofferdam is cumbersome, and it is easy to be restricted by construction conditions. In this paper, we mainly study the structure design and construction technology of rubber panel of earth rock cofferdam, and on the new type of cofferdam were feasibility analysis, the experimental method of rubber durability were analyzed, and further analysis of the feasibility of rubber of earth rock cofferdam.
