This invention relates to a support structure and construction method for narrow, deep foundation pits, belonging to the field of foundation pit excavation and support. Its purpose is to improve the excavation and support performance of narrow, deep foundation pits and reduce safety risks. The underground diaphragm wall is formed by diaphragm segments of each stepped foundation pit. Between adjacent diaphragm segments, the root of the upper diaphragm segment interlocks with the top of the lower diaphragm segment, and is anchored by pre-stressed rebound anchors passing through the interlocking portions of the two adjacent diaphragm segments. During construction, anchor piles are driven in for pre-support, then the corresponding stepped foundation pit is excavated, and the diaphragm segment construction is completed. Finally, pre-stressed rebound anchors are driven between the diaphragm segment under construction and the adjacent upper diaphragm segment. This fundamentally realizes the principle of "supporting before excavation and strengthening support while excavating," avoiding instability caused by prolonged exposure of the exposed surface after foundation pit excavation. The pre-stressed rebound anchor increases the pre-stress value of the support wall, thereby improving the stability of the underground diaphragm wall support.
