Collapsible loess stratum tunnel open-face construction method rapid construction method
The invention discloses a collapsible loess stratum tunnel open-face construction method rapid construction method. The method comprises the following steps that 1, a slope is excavated, wherein (1) a slope top section and a drainage ditch are arranged; (2) excavating a side slope; (3) side slope renovation; (4) trimming a base surface; 2, slope supporting: (1) anchor rod supporting; (2) supporting a reinforcing mesh; (3) spraying concrete; 3, permanent supporting is conducted; 4, excavating a tunnel portal; and 5, backfilling the open cut tunnel. The open construction method for the tunnel in the collapsible loess stratum is clear in structure and reasonable in construction step, the tunnel construction safety can be guaranteed, and the construction progress is accelerated.
一种湿陷性黄土地层隧道明做法快速施工方法，包括以下步骤：步骤1：边坡开挖：(1)设置坡顶截、排水沟；(2)边坡开挖；(3)边坡整修；(4)基面修整；步骤2：边坡支护：(1)锚杆支护；(2)钢筋网支护；(3)喷射混凝土；步骤3：永久支护；步骤4：洞门开挖；步骤5：明洞回填。本发明的湿陷性黄土地层隧道明做法快速施工方法结构明确，施工步骤合理，既能够保证隧道施工安全，又加快了施工进度。
