一、引言重力式空箱码头墙后接缝处理的方法,以往习惯采用抛石棱体混合倒滤层或采用倒滤井的作法。采用抛石棱体混合测滤层,材料消耗大,很不经济。而采用倒滤井,以分层级配或混合级配碎石作为倒滤材料,收到了良好的效果。但在空心方块接缝处设置倒滤井,结构上需作特殊处理以形成井腔,无疑给模板设计及钢筋绑扎带来较大困难。且填充碎石倒滤材料,也是一项费时费工的水下工序。最近几年来,采用编织布作倒滤材料,使这项工作得以简化。而本文介绍的是另一种墙后接缝处理的新方法,在重力式消浪室施工中收到
I. INTRODUCTION The gravity septic tank terminal wall seams are treated by the usual practice of using a stone-throwing prism filter or a filter-back well. Using riprap pyrite mixing filter layer, material consumption, it is not economical. The use of inverted filter wells to graded gradation or mixed graded as the filter material, received good results. However, the hollow block seams set up at the filter backfill, the structure required for special treatment to form a well chamber, no doubt to the template design and steel banding bring greater difficulties. And fill gravel filter material, but also a time-consuming underwater process. In recent years, the use of woven cloth filter material for refresher, to simplify this work. This article describes another new method of seams after the wall treatment received in the construction of gravity-type wave room
