Anchorage structure suitable for gravel-cobble soil layer and construction method thereof
The invention relates to the technical field of bridge engineering, in particular to an anchorage structure suitable for a gravel-cobble soil layer and a construction method of the anchorage structure. The anchorage structure comprises a grouting gravel body, a concrete anchor disc and a grouting surrounding rock body. The grouting gravel body is used for being arranged in an anchor hole, in the length direction of the grouting gravel body, the area of a first end face of the grouting gravel body is smaller than that of a second end face of the grouting gravel body, and the grouting gravel body is provided with two overhaul channels in a penetrating mode in the length direction of the grouting gravel body; the concrete anchor disc is connected to the second end face, and the concrete anchor disc is used for being connected with a suspension bridge main cable penetrating through a maintenance channel; the grouting surrounding rock body surrounds the grouting gravel body and is connected with the grouting gravel body through steel bars, and the grouting surrounding rock body is formed by grouting in a gravel-cobble soil layer. The construction method is low in construction difficulty, high in construction safety and capable of being suitable for the application environment of steep gravel-cobble soil layers in canyon landforms.
本申请涉及桥梁工程技术领域，具体涉及一种适用于卵砾石土层的锚碇结构及其施工方法。其中，锚碇结构包括注浆碎石体、混凝土锚盘和注浆围岩体；所述注浆碎石体用于设置于锚洞内，在所述注浆碎石体的长度方向上，所述注浆碎石体的第一端面面积小于第二端面面积，沿所述注浆碎石体的长度方向，所述注浆碎石体贯通设置有两个检修通道；所述混凝土锚盘连接于所述第二端面，所述混凝土锚盘用于连接穿过检修通道的吊桥主缆；所述注浆围岩体环绕所述注浆碎石体并通过钢筋与所述注浆碎石体连接，所述注浆围岩体通过在卵砾石土层中注浆成型。本申请施工难度较低、施工安全性高，能够适用于峡谷地貌中地形陡峭的卵砾石土层的应用环境。
