钻孔灌注桩是先采用人力挖掘、钢管挤土或机械钻孔等方式在地基土中形成桩孔,再在其中放入钢筋笼,最后灌注混凝土形成桩体。目前,钻孔灌注桩在建筑工程中的应用尤其广泛,且可有效解决泥浆排放、缩径、断桩及塌孔等问题。在本案,笔者以XX高层建筑工程为例,探讨钻孔灌注桩施工技术的应用价值。 Bored pile is the first manpower excavation, pipe squeezing soil or mechanical drilling holes in the formation of foundation soil, and then into the steel cage, and finally pouring concrete to form the pile. At present, the application of bored piles in construction engineering is particularly wide, and it can effectively solve the problems of mud discharge, diameter reduction, broken piles and hole collapse. In this case, the author takes XX high-rise building as an example to discuss the application value of bored pile construction technology.
