Suspension bridge anchorage diaphragm wall foundation and construction method thereof
The invention relates to the technical field of bridge engineering, in particular to a suspension bridge anchorage diaphragm wall foundation and a construction method thereof.The suspension bridge anchorage diaphragm wall foundation comprises a plurality of bored piles and diaphragm wall groove sections with the same number as the bored piles, and the bored piles are used for being arranged in the circumferential direction of the circular design contour of a diaphragm wall at intervals; two connecting grooves are symmetrically formed in each drilling pile along one radial surface of the drilling pile; each underground diaphragm wall groove section is arranged between every two adjacent drilled piles, and the ends of the underground diaphragm wall groove sections are arranged in the connecting grooves in a clamped mode. The problems that in the prior art, for an ultra-large-diameter underground diaphragm wall limited by slot milling machine equipment, the wall body thickness of the underground diaphragm wall in the prior art is difficult to exceed 1.5 m, but for an ultra-deep underground diaphragm wall foundation, enough out-of-plane rigidity and flexural capacity are difficult to provide due to the wall body thickness of 1.5 m can be solved.
本发明涉及桥梁工程技术领域，具体涉及一种悬索桥锚碇地连墙基础及其施工方法，该悬索桥锚碇地连墙基础包括：多根钻孔桩和与所述钻孔桩数量相同的地连墙槽段，多根钻孔桩用于沿地连墙圆形设计轮廓的周向间隔设置，且每一所述钻孔桩沿其一径向面对称开设有两个连接槽；每一所述地连墙槽段设于相邻两根钻孔桩之间，且所述地连墙槽段的端部卡设在所述连接槽内。本申请能够解决现有技术中对于超大直径、受限于铣槽机装备，现有技术地连墙的墙身厚度难以超过1.5m，但超深的地连墙基础而言，存在1.5m墙身厚度难以提供足够的面外刚度和抗弯承载力的问题。
