Sheet pile type anchorage structure and construction method thereof
The invention relates to a sheet pile type anchorage structure and a construction method thereof. The sheet pile type anchorage structure comprises a rock-socketed foundation, an anchor chamber and aplurality of vertical sheet piles which are integrally formed in a pouring mode, wherein the anchor chamber is arranged above the rock-socketed foundation, and the sheet piles are arranged below the rock-socketed foundation in parallel and located on the side, which is close to a bridge, of the rock-socketed foundation. During construction, a foundation pit of the rock-socketed foundation is excavated firstly, then sheet pile grooves are excavated through a groove milling machine, pouring of the sheet piles and the rock-socketed foundation is conducted synchronously, and finally, constructionof other structures is conducted. The anti-sliding and anti-overturning capacity of the foundation is enhanced through the vertical and horizontal plate end bearing capacity provided by the sheet piles and the friction force of the side walls, the sheet pile type anchorage structure can well adapt to the situation that the strength of ground surface bed rock is low, the material consumption and the foundation excavation scale of the rock-socketed anchorage can be greatly reduced, and the construction cost is reduced.
本申请涉及一种板桩式锚碇结构及其施工方法。该板桩式锚碇结构包括嵌岩基础、锚室和若干个竖直的板桩，三者为一体浇筑成型；锚室设于嵌岩基础上方，板桩平行排列在嵌岩基础下方，且位于嵌岩基础靠近桥梁的一侧。施工时，首先开挖嵌岩基础基坑，然后使用铣槽机开挖板桩槽，再同步进行板桩、嵌岩基础的浇筑，最后进行其他结构施工。本发明通过板桩提供的竖向及水平向的板端承载力及侧壁的摩擦力，来增强基础抗滑移、抗倾覆的能力，能较好地适应地表基岩强度较低情况，可大幅减小嵌岩锚碇的材料用量和基础开挖规模，降低工程造价。
