振冲防渗板墙技术是在振动沉桩基础上研制的一项新技术。采用该技术,可在松散地层中形成一定形状的柔性防渗墙体,应用于江河堤防的防渗加固,与一般成墙方式不同的是该技术辅以射流冲切土体,有利于成槽和成墙,提高施工速度。本文对振冲防渗板墙技术的基本原理、施工设备及工艺,防渗体的形成、性状、工程应用和质量检查方法等方面作了较为系统的阐述。 Vibrating impervious wall technology is a new technology developed on the basis of vibration pile sinking. Using this technology, flexible impervious walls with a certain shape can be formed in loose stratum, which is applied to seepage prevention and reinforcement of embankments of rivers. The difference with the general method of wall formation is that the technology is supplemented by jet punching of soil so as to facilitate the formation of grooves And become a wall, improve the construction speed. This paper systematically elaborates the basic principles of vibration-proof seepage-proof wall technology, construction equipment and technology, the formation of impervious body, traits, engineering application and quality inspection methods.
