Construction method of deep foundation pit lattice type tower crane foundation
The invention belongs to the field of tower crane construction, and discloses a construction method of a deep foundation pit lattice type tower crane foundation, which comprises the following steps: S1, accurately positioning a cast-in-situ bored pile foundation; s2, drilling construction is conducted, specifically, after drilling is conducted to the embedding depth of the latticed column, a reamer is adopted for drilling and reaming, and then a cast-in-place pile hole continues to be drilled; s3, a welding connector of the pile foundation reinforcement cage and the latticed column is placed; s4, concrete is injected into the drilled hole till the position of the drilled hole is submerged, and after the concrete reaches the set strength, the drilled hole is filled with cement mortar; s5, manufacturing a steel platform; and S6, construction of the bearing platform is completed on the steel platform. The reamed hole is drilled in the set position of the drilled hole, the latticed column and the pile foundation reinforcement cage are connected and placed in the drilled hole, then the concrete is poured, the concrete forms the boss at the reamed hole, the latticed column is anchored in the boss, the connecting strength of the latticed column and the pile foundation is improved, a foundation pit does not need to be excavated, a lower bearing platform does not need to be poured, the construction period is shortened, and the construction efficiency is improved. And the manufacturing cost is reduced.
本发明属于塔吊施工领域，公开了一种深基坑格构式塔吊基础的施工方法，包括：S1、钻孔灌注桩桩基精确定位；S2、钻孔施工：钻孔至格构柱的埋设深度后，采用扩孔钻钻设扩孔，再继续钻设灌注桩桩孔；S3、放入桩基钢筋笼与格构柱的焊接连接体；S4、向钻孔内注入混凝土至没过扩孔的位置，待混凝土达到设定强度后，采用水泥砂浆填充钻孔；S5、制作钢平台；S6、在钢平台上完成承台的施工。本发明采用在钻孔的设定位置钻设扩孔，格构柱与桩基钢筋笼连接放置于钻孔内后，浇筑混凝土，混凝土在扩孔处形成凸台，格构柱锚固于凸台内，增加了格构柱与桩基的连接强度，采用该方法无需开挖基坑浇筑下承台，缩短了工期，降低了制作成本。
