Pressure-resistant highway subgrade gravel pile anti-vibroflotation outer protection structure and using method thereof
The invention belongs to the field of vibroflotation resistance of highway subgrade gravel piles, and particularly relates to a pressure-resistant vibroflotation-resistant outer protection structure for highway subgrade gravel piles and a using method of the pressure-resistant vibroflotation-resistant outer protection structure. Pile grooves are uniformly formed in the surface of the roadbed; a gravel pile assembly is arranged in the pile groove. The gravel pile assembly comprises a gravel pile core and an outer protection assembly. The outer protection assembly is placed in the pile groove. The outer protection structure comprises stand columns and transverse bars. The transverse ribs are of an annular structure and are evenly distributed in the vertical direction. The surfaces of the transverse ribs are jointly and fixedly connected with stand columns which are evenly arranged. A gravel pile core is arranged in the outer protection assembly. Through the design of the outer protection assembly in the gravel pile assembly, an integral structure with the outer protection assembly as a framework can be formed, a compaction structure of a gravel pile core can be formed under the soft land condition, the pressure resistance and the bearing capacity of the gravel pile assembly are improved, and the settlement problem of a highway pavement is solved.
本发明属于公路路基碎石桩抗振冲领域，具体的说是耐压型公路路基碎石桩抗振冲外护结构及其使用方法，包括路基和碎石桩组件；所述路基的表面开设有均匀布置的桩槽；所述桩槽的内部设有碎石桩组件；所述碎石桩组件包括有碎石桩芯和外护组件；所述外护组件放置于桩槽的内部；所述外护结构包括有立柱和横筋；所述横筋为环状结构设计，且竖立方向均匀分布；所述横筋的表面共同固连有均匀布置的立柱；所述外护组件的内部设有碎石桩芯；通过碎石桩组件中的外护组件设计，可以形成以外护组件为骨架的整体结构，在松软的土地条件下，可以形成碎石桩芯的压实结构，提高了碎石桩组件的耐压性和承载力，减少公路路面的沉降问题。
