Steel bar planting method in pile foundation underpinning construction
The invention discloses a steel bar planting method in pile foundation underpinning construction. The steel bar planting method comprises the steps that firstly, a plurality of steel bar planting height layers which are sequentially arranged at intervals from top to bottom are preset on a pile foundation to be subjected to steel bar planting; secondly, a plurality of steel bar planting holes are drilled in one steel bar planting height layer, the steel bar planting holes extend from the outer side face of the pile foundation to the interior of the pile foundation, cleaning and ash removal areconducted on the steel bar planting holes, anchoring glue is injected into the steel bar planting holes, prefabricated connecting steel bars are inserted into the steel bar planting holes into which the anchoring glue is injected, and steel bar planting of the steel bar planting height layer is completed; and the process is repeated for conducting steel bar planting on other steel bar planting height layers one by one. According to the steel bar planting method in pile foundation underpinning construction, the influence on the structural strength and stability of the pile foundation in the steel bar planting process can be greatly reduced, the construction safety is guaranteed, and the underpinning construction quality of the whole pile foundation is guaranteed.
本发明公开了一种桩基托换施工中的植筋方法，该方法是先在待植筋的桩基上预设多个由上至下依次间隔布置的植筋高度层；然后在一个植筋高度层上钻出多个植筋孔，该植筋孔自桩基的外侧面向桩基内部延伸，对各植筋孔进行清洁除灰，然后向各植筋孔中注入锚固胶，再向每个注入锚固胶的植筋孔中插入安装预制的连接钢筋，完成该植筋高度层的植筋；再重复前述过程对其余植筋高度层逐个进行植筋。该植筋方法可大大降低植筋过程中对桩基结构强度及稳定性造成的影响，保障施工的安全性，以及整个桩基托换施工质量。
