摘要
高填方地区的桩基础在钻成孔过程中,由于施工技术及地质条件的影响,容易出现塌孔现象,因此成孔质量难以控制.论文以山西省某高填方储煤场新建储煤棚为实例,针对 6 种塌孔处理方法,分别从技术可行性、经济可行性两方面进行探讨,最终采用回填红黏土加固钻孔侧壁的方法顺利完成了全部钻孔施工.
Abstract
During the drilling process of pile foundation in high fill area,due to the influence of construction technology and geological conditions,hole collapse is easy to occur,so the hole quality is difficult to control.Taking the newly built coal storage shed in a high-filled coal storage yard in Shanxi Province as an example,this paper discusses six methods of hole collapse treatment from the technical feasibility and economic feasibility,and finally successfully completes all the drilling construction by backfilling red clay to reinforce the side wall of the hole.
