塑性砼防渗墙施工质量控制

塑性砼防渗墙施工技术用于广西水库大坝防渗工程还不多见,小江水库塑性砼防渗墙工程是迄今为止广西水利同类工程中规模最大的,总投资1 300多万元.塑性砼防渗墙为隐蔽工程,施工中的质量问题不易发现,必须对施工中的泥浆、造孔、清孔换浆、塑性砼浇筑等关键工序进行严格的过程控制,使其满足规范和设计要求,才能保证最终的工程质量.

Quality control of plastic concrete impervious wall construction

It is still not frequently seen that plastic concrete impervious wall construction technology is applied at reservoir main dam impervious works in Guangxi. With a total investment of more than 13 million yuan RMB, the plastic concrete impervious wall of Xiaojiang reservoir is the largest work of the same type of water conservancy projects in Guangxi. It is difficult to find the quality defect of plastic concrete impervious wall since it is a hidden construction work. The key construction sequences such as slurry, boring, hole cleaning, slurry replacement, plastic concrete grouting etc., must be subject to strict progress control up to requirements of standard and design, so as to ensure the final construction quality.
