Telescopic horizontal cantilever slide-resistant pile capable of solving tunnel bias and construction method of telescopic horizontal cantilever slide-resistant pile
The invention discloses a telescopic horizontal cantilever anti-slide pile for solving tunnel bias pressure and a construction method thereof.The telescopic horizontal cantilever anti-slide pile is arranged on the bias pressure side of a tunnel and comprises a vertically-arranged reinforcement cage, a horizontally-arranged telescopic horizontal cantilever and concrete wrapped between the reinforcement cage and the telescopic horizontal cantilever; one end of the telescopic horizontal cantilever is connected with the side wall of the top face of the slide-resistant pile built-in section reinforcement cage, and the other end of the telescopic horizontal cantilever extends towards the lower portion of the tunnel. The cantilever structure has the advantages that the bias pressure part of the rock-soil body can be converted into the vertical load borne by the cantilever structure, and the bias pressure load borne by the tunnel is reduced; the cantilever structure can resist tunnel inverted arch floating caused by bias voltage and the like; the self-strength of the rock-soil body under the cantilever structure is effectively utilized, deformation of the rock-soil body in front of the built-in section of the anti-slide pile is hindered, the bearing capacity of the anti-slide pile is improved, the length of the built-in section of the anti-slide pile and the sectional area of the anti-slide pile can be reduced, and the construction cost and the material cost are saved; the telescopic horizontal cantilever facilitates construction of a cantilever structure in a pile hole.
本发明公开了一种解决隧道偏压的可伸缩水平悬臂抗滑桩及其施工方法，可伸缩水平悬臂抗滑桩设于隧道偏压侧，可伸缩水平悬臂抗滑桩包括竖向设置的钢筋笼、水平向设置的可伸缩水平悬臂及包裹于两者间的混凝土，可伸缩水平悬臂一端同抗滑桩嵌固段钢筋笼的顶面侧壁连接、另一端朝向隧道的下方延伸。本发明的优点是：可将岩土体的偏压部分转化为悬臂结构承受的竖向荷载，减少隧道受到的偏压荷载；悬臂结构可以抵抗偏压等引起的隧道仰拱上浮；有效利用了悬臂结构下岩土体自身强度，阻碍了抗滑桩嵌固段前方岩土体变形，提高抗滑桩的承载能力，可减少抗滑桩嵌固段长度和抗滑桩截面面积，节省施工成本和材料成本；可伸缩水平悬臂便于桩孔内悬臂结构的施工。
