隧道掘进水压爆破在铁路隧道的应用

Application of Tunnel Excavation Hydraulic Blasting in Railway Tunnels

水压爆破技术由于施工速度快和价格低的特点,在铁路隧道建设方面大范围应用,但是并不是在所有的隧道爆破中都实用,比如说在土质较差的环境中,需要减少对周边环境的影响,使用安全高效的控制爆破振动装置来减少对外部环境影响。目前来说,城市地下工程设施较多,所以对爆破要求越来越高,过去的常规爆破已经无法满足地下施工要求,所以水压爆破技术因其"三提高一保护"的优势得到广泛应用与推广。本文针对水压爆破技术现状、优势以及使用进行介绍,便于掌握水压爆破技术,建设优秀铁路建设。

The water pressure blasting technology because of the characteristic of the construction speed and low price, wide range of application in railway tunnel construction, but not in all of the tunnel blasting are practical, such as poor in soil environment, the need to reduce the impact on the surrounding environment, the use of safe and efficient control blasting vibration device to reduce the external environmental impact.At present, urban underground engineering facilities is more, the blasting demand is higher and higher, so the past conventional blasting has been unable to meet the requirements of underground construction, so the water pressure blasting technology because of its ＂San Di Gao a protection＂ advantage is widely used and promoted. This paper introduces the current situation, advantages and use of water pressure blasting technology, so as to master hydraulic blasting technology and build excellent railway construction.
