Abstract: As a newtechnology and construction method, prestressed channel vacuum- treated mud jacking was applied in projects recent years. By comparison to traditional way, it has many advantages, such as that it can ensure the compactness and intensity of slurry, and also can shorten the time of mud jacking. This article, to set a useful example to similar projects, introduced the principle

摘要： 预应力管道真空辅助压浆法施工是近年来开始逐步在工程中得以使用的新技术、新工艺。与传统的压浆施工法进行对比, 真空压浆具有能保证浆体的密实度和强度、缩短压浆时间等优点。本文对后张法预应力管道真空压浆法的原理及工艺流程分别做详细介绍, 为其在工程中更广泛的应用提供有益的借鉴。
