摘要
旋挖桩成孔在遇到富含大块径卵石的砂卵石层时,即使采取有效的护壁方法,也难以将大块径卵石一次成功取出,不能确保在有限的施工时限内完成旋挖桩成孔。提出一种固结后及时旋挖的施工方法,可以有效解决富含大块径卵石的砂卵石层旋挖桩成孔难题。同时可以缩短工期,减少对附近建筑物的影响,具有良好的效果。
Even if effective wall protection method is adopted,it is difficult to take out the large diameter pebbles successfully at one time when encountering sand pebble layer rich in large diameter pebbles,which cannot ensure the completion of hole-forming for rotary pile in limited construction time limit.A construction method of timely rotary excavation after the consolidation is proposed,which can effectively solve the hole-forming problem of rotary excavation pile in sandy pebble layer rich in large size pebbles.At the same time,it can shorten the construction period and reduce the impact on the nearby buildings,which has achieved good effects.
