摘要
防渗墙是一种用于修筑松散透水层、土石坝工程的构件.为进一步明确水库堤坝工程中防渗墙施工技术的实际应用,研究以塑性混凝土防渗墙施工技术为例,分别从施工准备阶段、混凝土试验、槽段布置与浇筑等方面,对该技术施工要点展开了分析.最后应用钻芯取样法与超声波检测技术对工程防渗墙质量进行检测.结果表明,塑形混凝土防渗墙施工技术在水库堤坝工程中的抗压强度等各项指标均达到设计标准,墙体完好无裂缝,故其符合工程设计要求.
Abstract
Anti-seepage wall is a kind of component used to prevent seepage in loose permeable layer and earth-rock dam.In order to further clarify the practical application of the anti-seepage wall construction technology in reservoir dam engineering,the plastic concrete anti-seepage construction technology is taken as an example,and the construction key points of this technology are analyzed from the aspects of construction preparation stage,concrete test,channel layout and pouring.Finally,the core sampling method and ultrasonic detection technology are used to detect the quality of engineering cutoffwall.The results show that the compressive strength and other indexes of the plastic concrete cutoffwall construction technology in the dam engineering meet the design standards,and the wall is intact without cracks,which meets the engineering design requirements.
