The invention discloses a belled pile for a building immersed tube. The belled pile comprises an upper-section steel tube, a cast-in-place concrete base and a reinforcement cage, a cast-in-place column body is arranged at the bottom end of the upper-section steel tube, the cast-in-place concrete base is arranged at the bottom end of the cast-in-place column body, cross branches are evenly arrangedon the outer side wall of the cast-in-place column body, the reinforcement cage is arranged inside the cast-in-place column body, the reinforcement cage is formed by evenly arranging a plurality of vertical steel bars in a circular ring shape, annular steel bars are evenly arranged on the outer sides of the vertical steel bars from top to bottom, triangular supporting steel bars are arranged on the inner sides of the annular steel bars, and hollow steel tubes are welded to the inner sides of the triangular supporting steel bars. According to the belled pile, the bearing capacity and impact resistance are relatively high, the stability is good, the use amount of concrete can be reduced, and therefore material waste is reduced.
本发明公开了一种建筑沉管用扩底桩，包括上段钢管、现浇砼底座和钢筋笼，所述上段钢管的底端设置有现浇柱身，且现浇柱身的底端设置有现浇砼底座，所述现浇柱身的外侧壁上均匀设置有十字型分支，所述现浇柱身的内部设置有钢筋笼，所述钢筋笼由多根竖直钢筋呈圆环形均匀排列而成，且竖直钢筋的外侧从上到下均匀设置有环形钢筋，所述环形钢筋的内侧均设置有三角形支撑钢筋，且三角形支撑钢筋的内侧焊接设置有空心钢管。本发明承载力和抗冲击力较强，稳固性好，且可以减少混凝土的用量，从而减少材料浪费。
