Rock-socketed unequal-height bridge composite pile group foundation suitable for soft foundation and construction method thereof
The invention discloses a rock-socketed unequal-height bridge composite pile group foundation suitable for a soft foundation and a construction method of the rock-socketed unequal-height bridge composite pile group foundation, and relates to the technical field of bridge construction. Pile foundations are evenly distributed and fixed to the bottom end of the bearing platform, first shear walls are fixed between the tops of the multiple pile foundations located at the same end, second shear walls are fixed between the multiple first shear walls located on the same side, and grouting reinforcing grooves are formed between the second shear walls at the two adjacent ends. Through cooperation of the pile foundations, the shear walls and the bearing platform, the rock-socketed unequal-height bridge composite pile group foundation gives full play to the mechanical property of a foundation bearing layer, the rock-socketed depth of the pile foundations is reasonably set according to the soil body strength of the bearing layer, meanwhile, through cooperation of the multiple pile foundations and the shear walls, good vertical and horizontal bearing capacity can be provided, and the foundation structure is simple and convenient to construct. And the rock-socketed depth of the pile foundation and the shear wall is reasonably set according to the characteristics of the bearing stratum.
本发明公开了一种适用于软基的嵌岩不等高桥梁复合群桩基础及其施工方法，涉及桥梁施工技术领域。本发明包括承台，承台的底端均布固定有桩基，位于同一端多个桩基顶部之间固定有第一剪力墙，位于同一侧多个第一剪力墙之间固定有第二剪力墙，相邻两端第二剪力墙之间形成注浆加固槽。本发明通过桩基、剪力墙和承台的配合，嵌岩不等高桥梁复合群桩基础充分发挥了基础持力层的力学性能，根据持力层的土体强度合理设置桩基的嵌岩深度，同时通过多个桩基和剪力墙的配合，可以提供较好的竖向和水平承载能力，且根据持力层岩层的特性，合理设置桩基和剪力墙的嵌岩深度。
