摘要
在部分地下工程中,管道工程会遇到坚硬岩层,采取科学有效的破岩掘进技术,同时保证工程进度和安全性,对于工程顺利开展至关重要。首先对非爆破掘进技术进行概述,阐析常用的技术手段,在此基础上以具体工程为例,分析顶管施工中遇到坚硬岩层时采用非爆破破岩掘进技术的效果及施工注意事项等。旨在通过此次研究,为类似工程施工提供参考。
In some underground projects,the pipeline project will encounter hard rock strata.It is very important for the smooth development of the project to adopt scientific and effective rock breaking and tunneling technology while ensuring the progress and safety of the project.Firstly,this paper summarizes the non blasting excavation technology and analyzes the common technical means.On this basis,taking a specific project as an example,this paper analyzes the effect and construction precautions of non blasting rock breaking excavation technology when encountering hard rock stratum in pipe jacking construction.The purpose of this study is to provide reference for similar engineering construction.
