Arch bridge large-angle batter pile excavator retreating type slant layered deslagging construction method
The invention relates to the technical field of bridge construction, in particular to an arch bridge large-angle raking pile excavator retreating type inclined layered deslagging construction method which comprises the following steps that S1, pre-cleaning is conducted, specifically, to-be-caved or possibly-caved dangerous rocks on edges and front slopes are removed; s2, protection is conducted, specifically, the inclined pile cavern edge and an upward slope body are reinforced; the interiors of the inclined piles are blasted, an excavator is driven into the gentle slopes in the hole in a micro-crank arm mode, the excavator excavates the gentle slopes layer by layer, and the angle of each layer of gentle slope is smaller than or equal to 25 degrees; and S4, deslagging is conducted, specifically, the excavator retreats upwards along the inclined pile gentle slope to go out of the hole, rock ballast is abandoned to a rock ballast collecting site, and the effects of smooth deslagging of the inclined pile foundation, shortening of the construction period and reduction of the construction cost are achieved.
本申请涉及桥梁施工技术领域，尤其是涉及一种拱桥大角度斜桩挖掘机退行式斜向分层出渣施工方法，包括以下步骤：S1、预清理：清除边、仰坡上即将崩落或者可能崩落的危石；S2、防护：对斜桩洞室边、仰坡坡体进行加固；S3、开挖：对斜桩内部进行爆破，挖掘机采用微曲臂的方式驶入洞内缓坡，挖掘机采用逐层缓坡开挖，每层缓坡角度小于或者等于25度；S4、出渣：挖掘机沿斜桩缓坡向上退行出洞，将石渣弃至石渣收集地点，达到了使斜桩基础顺利出渣，缩短施工周期，降低施工成本的效果。
