The invention provides a deepened foundation pit supporting pile lap joint reinforcing structure and a construction method. The reinforcing structure comprises a newly-added beam and a plurality of first supporting piles arranged along the side wall of a foundation pit. Second supporting piles are arranged on the sides, facing the foundation pit, of the first supporting piles, and the upper portions of the second supporting piles are overlapped with the lower portions of the first supporting piles; the upper portions of the second supporting piles are exposed out of the deepened pit bottom of the foundation pit, and the parts, exposed out of the deepened pit bottom, of the second supporting piles are all connected with the newly-added beams. Anchor cables anchored into a soil layer of the side wall of the foundation pit are arranged on the newly-added beams; and a soil retaining plate is arranged between the parts, exposed out of the deepened pit bottom, of every two adjacent second support piles. The construction process is simple to operate; effective lap joint of new and old support piles is formed, and reinforcement of an original support system is achieved; the structure of an original supporting system is utilized to the maximum degree, safety is high, cost is low, quality is easy to control, and the engineering progress can be accelerated.
本发明提供了一种加深基坑支护桩搭接加固结构及施工方法，加固结构包括新增梁、沿基坑的侧壁布置的多根第一支护桩；所述第一支护桩面向基坑的一侧均设有第二支护桩，第二支护桩的上部与第一支护桩的下部重叠；第二支护桩的上部露出于基坑的加深坑底，第二支护桩露出于加深坑底的部分均与所述新增梁连接；所述新增梁上设有锚入基坑侧壁的土层中的锚索；每相邻的两根第二支护桩露出于加深坑底的部分之间均设有挡土板。本发明施工工艺操作简单；形成了新旧支护桩的有效搭接，实现了对原支护体系的加固；最大程度的利用了原有支护体系的结构，安全性高，成本低，质量易于控制，有利于加快工程进度。
