Construction method of slide-resistant pile
The invention provides a construction method of a slide-resistant pile at a tunnel portal. The construction method specifically comprises the following steps that S1, a site is leveled; S2, measuring and positioning are conducted, specifically, the center point of a hole pile is set out, the accurate position of a pile hole is determined, after setting-out is completed, the mutual positions of adjacent hole piles nearby are subjected to distance pulling, and the pile position is checked; S3, hole pile excavation is conducted, specifically, lifting equipment is mounted, the stacking distance of discharged slag is not less than 5m from the hole position, the discharged slag is hardened within the range of 1m around the hole, and guardrails are arranged on the periphery of the hole; and the height of a locking opening is not less than 30cm higher than the ground; S4, slag discharging hoisting equipment is mounted; S5, sectional excavation is conducted; S6, wall protecting steel bars are manufactured and mounted; S7, rock stratum geological excavation treatment is conducted, specifically, construction is conducted through an in-hole water milling drilling method; S8, steel bars are manufactured, mounted and hoisted; S9, sounding pipes are mounted on the inner sides of the pile body steel bars and firmly bound with the vertical steel bars; and S10, concrete pouring is conducted, and the slide-resistant pile is completed. According to the construction method, the slide-resistant pile is adopted for supporting and blocking, the heights of a side slope and a pitching slope are effectively decreased, roads around a tunnel are protected, the influence of the surrounding environment is small, and the efficiency is high.
本发明提供了一种隧道洞口抗滑桩施工方法，具体包括以下步骤：S1.场地平整；S2.测量定位：放出孔桩中心点，定出桩孔准确位置，放样完毕后，对附近相邻孔桩相互位置进行拉距，校核桩位；S3.孔桩开挖：安装提升设备，出渣堆放距离孔位不少于5m，孔周围1m范围内应硬化，周边设置护栏；锁口高度高出地面不小于30cm；S4.安装出渣吊运设备；S5.分节开挖；S6.护壁钢筋制作与安装；S7.岩层地质开挖处理：采取孔内水磨钻法施工；S8.制作钢筋、安装钢筋和吊装钢筋；S9.安装声测管在桩身钢筋内侧，与竖向钢筋绑扎牢固；S10.砼浇筑，抗滑桩完成。本发明采用抗滑桩支挡，有效减少了边坡、仰坡高度，保护了隧道周围的公路，周围环境影响小，效率高。
