Pile net type roadbed composite structure and construction method
The invention discloses a pile net type roadbed composite structure and a construction method, and relates to the technical field of high-speed railway roadbed structures, the technical scheme is that the pile net type roadbed composite structure comprises a plurality of main reinforcing areas and secondary reinforcing areas which are arranged at intervals, and each of the main reinforcing areas and the secondary reinforcing areas is composed of a pile foundation, a reinforced cushion layer and a soil roadbed; the pile foundations are arranged at intervals in the longitudinal direction and the transverse direction of the soil roadbed, the pile caps are arranged on the pile tops of the pile foundations, the reinforced cushion layer is arranged above the pile foundations, and the soil roadbed is arranged above the reinforced cushion layer. The wide-section station roadbed combined roadbed structure has the beneficial effects that a traditional roadbed structure is optimized, different types of foundation treatment modes are adopted in a station, the wide-section station roadbed combined roadbed structure with various section types is jointly formed, the combined roadbed structure adopts the same type in the cross section direction, and the combined roadbed structure is simple in structure and convenient to use. Transition in the depth direction within the reinforcing area range is not considered any more, subgrade settlement control is better achieved, and the construction process is controllable.
本发明公开了一种桩网式路基组合结构及施工方法，涉及高铁铁路路基结构技术领域，技术方案为，包括间隔设置的若干个主加固区以及次加固区，主加固区以及次加固区均由桩基、加筋垫层和土质路基组成，桩基沿土质路基纵、横向间隔设置，桩基的桩顶上设置桩帽，加筋垫层设置在桩基的上方，土质路基设置在加筋垫层的上方。本发明的有益效果是：通过对传统路基结构进行优化，提出在站场中采用不同类型的地基处理方式，共同构成断面类型多样的宽断面站场路基组合式路基结构，且在横断面方向上组合式路基结构均采用同一类型，不再考虑加固区范围内在深度方向上的过渡，更好的实现了控制路基沉降且施工过程可控。
