Replacement pile structure of slide-resistant pile for tunnel crossing side slope and construction method
The invention discloses a replacement pile structure of a slide-resistant pile for a tunnel crossing a side slope, the replacement pile structure is arranged below an existing building, the replacement pile structure comprises a counterfort retaining wall and a rotary excavating cast-in-place pile, the counterfort retaining wall comprises a beam, a heel slab, a wall panel and a counterfort, the beam is arranged between the heel slab and the wall panel, and the rotary excavating cast-in-place pile is arranged in the counterfort. One side of the beam is fixedly connected with the heel slab, the top of the beam is fixedly connected with the bottom of the front panel, the buttress is fixedly arranged at the top of the heel slab, the buttress is fixedly connected with the wall panel, the top of the rotary excavating cast-in-place pile penetrates through the bottom of the heel slab, and the top of the rotary excavating cast-in-place pile is fixedly connected with the heel slab. The replacement pile structure provided by the invention can reduce the influence of breaking the original anti-slide pile on the original structure in the tunnel construction process to the greatest extent, and ensures the safety and stability of the original structure and the tunnel in the tunnel construction process.
本发明公开了一种隧道穿越边坡抗滑桩的置换桩结构，置换桩结构设置于既有建筑物的下方，置换桩结构包括扶壁式挡土墙和旋挖灌注桩，所述扶壁式挡土墙包含梁、踵板、墙面板和扶壁，所述梁设置于踵板与墙面板之间，梁的一侧与踵板固定连接，梁的顶部与前面板的底部固定连接，扶壁固定设置于踵板的顶部，扶壁与墙面板固定连接，旋挖灌注桩的顶部贯穿踵板的底部，且旋挖灌注桩的顶部与踵板固定连接。本发明提供的置换桩结构能够最大程度降低隧道施工过程中破除原抗滑桩对原结构的影响，保障隧道施工过程中原结构和隧道本身的安全稳定。
