The invention relates to the field of basement construction, in particular to a basement bottom plate-based tower crane foundation construction method, which comprises the following steps of: determining the position of a tower crane foundation on a bottom plate; the bearing capacity of foundation soil under a basement bottom plate where the tower crane foundation is located is calculated, and it is ensured that the bearing capacity of the foundation meets the requirement; bottom plate top reinforcing steel bars are broken and removed, and the bottom plate top reinforcing steel bars are connected with tower crane foundation reinforcing steel bars; a tower crane foundation is poured; a jacking mechanism is arranged between the poured tower crane foundation and the structural floor slab; and a monitoring mechanism for monitoring the stress change of each jacking mechanism is arranged on each jacking mechanism. According to the construction method, through the modes that the broken bottom plate steel bars are connected with the tower crane foundation, the jacking mechanism is arranged to reversely jack the structural floor slab and the like, the bottom plate structure is prevented from being damaged by the eccentric load of the tower crane, and the related problem that the tower crane cannot be additionally arranged under the condition that the tower crane pile cannot be driven after the bottom plate structure is completed is solved; the construction safety and the use stability of the newly-added tower crane are ensured, and a reference is provided for the newly-added tower crane in subsequent construction scenes of the same type.

    本申请涉及地下室施工领域,尤其涉及一种基于地库底板的塔吊基础施工方法,包括以下步骤:在底板上确定塔吊基础的位置;对塔吊基础所在的地库底板下的地基土承载力核算,确保地基承载力满足要求;破除底板顶部钢筋,并将底板顶部钢筋与塔吊基础钢筋进行连接;浇筑塔吊基础;在浇筑后的塔吊基础与结构楼板之间设置顶撑机构;在各顶撑机构上设置监测其应力变化的监测机构。本申请施工方法通过破出底板钢筋与塔吊基础连接、设置顶撑机构反顶至结构楼板等方式,避免塔吊偏心荷载对底板结构造成破坏,解决了底板结构完成后无法施打塔吊桩情况下增设塔吊的相关问题,确保新增塔吊的施工安全与使用稳定,为后续同类型施工场景新增塔吊提供参照。
