摘要
风动潜孔钻机在块石层中成孔,是目前钻进工法中最简便高效的方法,袖阀管分段灌浆在灌浆工程中亦是很常用的施工工艺,文中详细介绍了两种工艺在加固松散块石路堤工程中的应用及其效果,并提出在施工中需改进和注意的问题。
Drilling in block-stone with DTH drill is the simplest and most efficient method,sleeve-valve tube grouting is also the common method in grouting project,this article will introduce you the applications and effectiveness in the construction of reinforce block-stone railway embankment with DTH drill and sleeve-valve tube grouting,then suggest the problem which need to improve in construction.
