Construction method of underpinning beam in pile foundation underpinning construction
The invention discloses a construction method of an underpinning beam in pile foundation underpinning construction. The construction method comprises the following steps that firstly, a groove is formed in the outer side face of a pile foundation to be underpinned and a plurality of connecting steel bars are implanted, then a steel bar framework connected with the connecting steel bars is formed by binding on the periphery of the pile foundation to be underpinned and a formwork is erected; and finally, concrete is poured and cured to obtain an underpinning beam. By the adoption of the construction method, the combination degree and the connection strength of the underpinning beam and the pile foundation to be underpinned can be improved, and the overall structural strength and the stress performance after the underpinning beam and the pile foundation to be underpinned are connected are improved.
本发明公开了一种桩基托换施工中的托换梁的施工方法，该施工方法是先在待托换桩基外侧面开设凹槽并植入若干连接钢筋，然后在待托换桩基外围绑扎形成与连接钢筋相连的钢筋骨架并支立模板，最后浇筑混凝土并养护后得到托换梁。采用该施工方法能够提高托换梁与待托换桩基的结合度和连接强度，提高托换梁与待托换桩基连接后的整体结构强度和受力性能。
