铜川电信生产楼是一幢高层建筑,其他基层级湿性黄土、湿陷高度18米。为消除湿陷性大幅度提高地基承载力,我们大胆尝试了用两种打桩工艺的结合,即灰土挤密桩成孔工艺和染填土桩的夯填工艺。使桩间土得到二次挤密。桩身用重填夯更加密实。达到了消除地基湿陷性及大幅提高地面耐力的目的。 Tongchuan telecommunications building is a high-rise buildings, other grass-roots wet loess, collapsed 18 meters high. In order to eliminate collapsibility and greatly improve the bearing capacity of foundation, we boldly tried to use a combination of two kinds of piling technology, that is, the process of forming lime-soil compaction pile and the filling technology of dyed soil-filled piles. So that the soil between the piles to squeeze twice. Pile with more compacting rammer. Achieved to eliminate collapsible foundation and significantly improve the ground endurance purposes.
