厚中粗砂层中多轴深层搅拌防渗墙的施工

Construction of Multiple Deep-Layer Mixed Seep-preventing Wall in Thick Medium Coarse Sand Bed

对于中粗砂层较厚的多轴深层搅拌防渗墙施工,通过改进钻头,采用中间钻头喷气施工工艺,能有效地提高施工效率。以潮州供水枢纽工程上埔堤防渗墙施工为例,介绍多轴深层搅拌在厚中粗砂层中的施工工艺及质量控制。

For the constructions of multiple deep- layer mixed seep- preventing wall in thick medium coarse sand bed, improving aiguille and using jet air from the middle aiguille can effectively improve the efficiency of the constructions and introduces workmanship. Combining with an example of Shangpu dam of Chaozhou water supply hinge project, this paper introduced a method of workmanship and quality control of which multiple deep - layer mixed seep - preventing wall in thick medium coarse sand bed.
