Anti-emptying self-compacting roadbed structure and construction method
The invention discloses an anti-emptying self-compacting roadbed structure and a construction method. The anti-emptying self-compacting roadbed structure comprises an original foundation and a filling roadbed arranged on the original foundation, a plurality of layers of obliquely inserted guide plates are arranged in the original foundation where the bottom and the two sides of the filled roadbed are located, and the guide plates are used for preventing the original foundation from being scoured by rising tide water flow and intercepting and accumulating silt particles in falling tide water flow so as to compact the original foundation; and the direction of obliquely inserting the guide plates into the original foundation is consistent with the rising tide water flow direction in the original foundation when the tide rises. The guide plates can effectively prevent a water flow from scouring an original foundation roadbed working area during flood tide, densification and compaction of a roadbed can be achieved through the water flow and pavement loads, and the self-compaction effect of the flow guide plate is gradually obvious as time goes on; therefore, the original foundation strength is improved, the soil permeability is greatly reduced, and the anti-seepage and anti-emptying effects are achieved.
本发明公开了一种防掏空的自密实型路基结构及施工方法，包括：原始地基及设置在原始地基上的填筑路基；所述填筑路基的底部及两侧所在的原始地基内均设置有多层倾斜插入的导流板，所述导流板用于阻挡潮汐涨潮水流对原始地基的冲刷，且截留并囤积潮汐落潮水流中的泥沙颗粒以夯实原始地基，所述导流板倾斜插入原始地基内的方向与潮汐涨潮时原始地基内的涨潮水流方向一致。本发明的导流板在涨潮时能够有效的阻隔水流对原始地基路床工作区的冲刷，且可以利用水流和路面荷载实现对路基的加密压实，其自密实效果随着时间的推移逐渐明显；从而提升原始地基强度并大幅度降低土体渗透性以实现防渗、防掏空效果。
