Foundation pit reverse construction method cast-in-place pile sounding pipe hoisting positioning construction structure
The invention relates to the technical field of foundation pit cast-in-place piles, and discloses a foundation pit reverse construction method cast-in-place pile sounding pipe hoisting positioning construction structure. The structure comprises a pile hole, a pile casing, a steel reinforcement cage lowering in the pile hole in a suspension manner and an extension steel bar, the extension steel bar is hoisted to the position above the pile hole through a crane, the steel reinforcement cage is provided with a main reinforcement, and a bottom sounding pipe is fixed to the inner side of the main reinforcement of the steel reinforcement cage. The top of the bottom sounding pipe is exposed on the ground; the extension steel bar is connected with an extension sounding pipe, the lower end of the extension steel bar is fixedly connected with the upper end of the main reinforcement, the lower end of the extension sounding pipe is fixedly connected and communicated with the upper end of the bottom sounding pipe, and the length of the bottom sounding pipe connected with the extension sounding pipe is larger than the depth of the pile hole; and through connection with the reinforcement cage, lowering in of the bottom sounding pipe, connection of the extension steel bar and the main reinforcement, and connection of the extension sounding pipe on the bottom sounding pipe, full-length arrangement and burying of a sounding pipe are rapidly realized, the use amount of steel bars is reduced, the construction cost is reduced, the extension installation efficiency of the sounding pipe is improved, and the cost is saved.
本发明涉及基坑灌注桩的技术领域，公开了基坑逆作法灌注桩声测管吊装定位施工结构，包括桩孔、护筒、悬空状下入在桩孔中的钢筋笼以及利用吊机起吊至桩孔上方的接长钢筋，钢筋笼具有主筋，钢筋笼的主筋的内侧上固定有底部声测管，底部声测管的顶部显露在地面上；接长钢筋上连接有接长声测管，接长钢筋的下端与主筋的上端固定连接，接长声测管的下端与底部声测管的上端固定连接并连通，底部声测管与接长声测管连接后的长度大于桩孔的深度；通过与钢筋笼连接在一起，下入底部声测管，利用接长钢筋与主筋的连接，在底部声测管上接上接长声测管，快速实现声测管通长布置埋设，减少钢筋使用量，降低施工成本，提高声测管接长安装效率，节约成本。
