Excavation method for arranging deslagging shortcut in steep cliff skewback slope area
The invention discloses an excavation method for arranging a deslagging shortcut in a steep cliff skewback slope area. Hoisting equipment is not required for deslagging, the single-time slag conveyingamount is effectively improved, the excavation progress is not influenced by the rotating speed of the hoisting equipment any more, the equipment investment is less and construction efficiency is high, the influence of the skewback slope excavation progress on the terrain condition is reduced, the construction difficulty is greatly reduced, and the deslagging shortcut is located in the skewback slope area. The deslagging shortcut is slightly influenced by the terrain conditions of a bridge site area, the deslagging shortcut is located in the skewback slope and closer to the inner side of a mountain body, the bearing capacity is high, the safety protection area is smaller during construction, and the safety coefficient is higher. Only two excavation main shortcuts are arranged in the skewback side slope area, the deslagging shortcut outside the area does not need to be arranged for each stage of side slope, the earthwork amount is effectively and greatly reduced, the damage area to thenatural surfaces of mountains on the two banks of the bridge site area and the influence on rivers are reduced, and the environmental protection benefit is high.
本发明公开了一种陡峭崖壁拱座边坡区域内布置出渣便道的开挖方法，采用本方法无需使用起重吊装设备出渣，有效提高单次运渣方量，开挖进度不再受起重吊装设备的轮转速度的影响，设备投入少、施工效率高，减小了拱座边坡开挖进度受地形条件的影响，施工难度大大降低，出渣便道位于拱座边坡区域内部，其布置受桥址区地形条件的影响小，出渣便道位于拱座边坡内部，更靠近山体内侧，承载能力高，施工时安全防护面积更少，安全系数更高，拱座边坡区域仅设置两条开挖主便道，无需针对每级边坡设置区域外的出渣便道，有效大幅减少土石方工程量，并且减少了对桥址区两岸山体自然表面破坏的面积以及对河流的影响，环保效益高。
