岩石非开挖钻进技术的研究

Study on Trenchless Drilling Technology

摘要:

非开挖铺设地下管线施工技术是一项广泛应用于市政建设、铁路交通、电力通讯、水利和石油天然气输送等领域的高新技术。而岩石非开挖施工则是近年来许多有实力的单位所涉足的一种施工难度大、施工技术含量高的施工领域。论述了非开挖基岩钻进的技术要点及在不同地层、不同管径施工条件下对非开挖回扩钻头的设计及选用。结合国内几个典型的施工实例，详细阐述了非开挖基岩钻进的施工工艺。展望了该技术的发展前景。

Abstract:

Trenchless technology for underground pipeline construction is a high technology, which is widely used in municipal construction, railway transport, electric-communication, conservancy and oil & natural gas transport. The paper discussed the main technical points of bedrock drilling, the design and selection of back reamers for different formations and drilling diameters, detailed construction technology of bedrock with typical engineering cases in China and prospected the future development.
