Roadbed reinforcing method for restraining soil slippage through continuous lateral confinement
The invention relates to a roadbed reinforcing method for restraining soil slippage through continuous lateral confinement. The roadbed reinforcing method comprises the steps that 1, tie bar machiningis performed; a tie bar is processed by a hot-rolled ribbed steel bar, a bolt sleeve is connected and lengthened, and a tool type impact head is arranged at a front end of the tie bar during laying;2, the tie bars are impacted and laid; a horizontal spacing of the tie bars is 4-6m or is calculated and determined according to lateral pressure of roadbed soil which can be resisted by combining tiebar tensioning and fastening with a side limiting wall; 3, a side limiting wall is constructed; high-fill roadbed side limiting walls are arranged according to the number of tie bars, the roadbed isreinforced according to one tie bar and is arranged conventionally, and more than two tie bars can be arranged in a layered mode and can also be arranged in a whole-width mode; 4, the tie bars are tensioned and fastened; a waterproof coating of an anchoring section needs to be removed before a through-wall tie bar is tensioned; and 5, a working well is built. The tie bars are arranged in the soilroadbed, roadbed soil is transversely restrained by applying a fastening force, lateral sliding of deep roadbed soil due to shear failure is effectively prevented, and a road bearing capacity is obviously improved.
本发明涉及一种连续侧限约束土体滑移的道路路基加固方法，步骤一：拉筋加工；拉筋采用热轧带肋钢筋加工，螺栓套筒连接接长，敷设时拉筋前端设有工具式冲击头；步骤二：冲击敷设拉筋；拉筋水平间距宜按4~6m或根据拉筋张拉紧固与侧限墙联合可抵抗路基土的侧向压力计算确定；步骤三：侧限墙施工；高填方路基侧限墙根据拉筋道数设置，路基按一道拉筋加固时按常规设置即可，两道以上拉筋可分层设置，也可整幅设置；步骤四：拉筋张拉紧固；穿墙拉筋张拉前需清除锚固段防水涂料；步骤五：工作井砌筑。本发明将拉筋设置在土路基中，通过施加紧固力，使路基土受到横向约束，有效阻止深层路基土受到剪切破坏产生侧向滑移，明显提高了道路承载能力。
