Roadbed treatment structure for road widening junction on deep soft foundation
The invention relates to a roadbed treatment structure for a road widening junction on a deep soft foundation, and belongs to the field of road widening engineering in deep soft foundation areas. A differential settlement treatment structure is adopted at the junction of an original road surface and the broadened pile-soil mixed roadbed soil for mutual construction; according to the differential settlement treatment structure, a pile-soil mixed roadbed is laid at the junction of the original road surface, a compaction layer is laid on the pile-soil mixed roadbed, and the compaction layer is flush with that of the original road surface; the junction between the original road surface and the compaction layer is covered with a reinforced plate layer, and the reinforced plate layer is coveredwith a steel-plastic grid; and a geogrid covers the upper part of the stiffened plate layer. The original road surface structure layer is reserved, the structural stability is enhanced by utilizing the strength of cement soil and the reinforcement effect of the reinforced plate geogrid steel-plastic grid, the roadbed stress is dispersed, and uneven differential settlement caused by different strengths of new and old road foundations is prevented.
本发明涉及一种深厚软基上道路拓宽交界处路基处理结构，属于深厚软基区域道路拓宽工程领域。在道路原路面与拓宽桩土混合路基土的交界处之间采用不均匀沉降处理结构相互构筑；该不均匀沉降处理结构在位于原道路路面的交界处铺设桩土混合路基，桩土混合路基上铺设压实层，压实层的高度与原道路路面齐平；位于原道路路面与压实层之间的交界处上覆盖加筋板层，加筋板层的上方覆盖钢塑格栅；加筋板层的上方覆盖土工格栅。本发明在保留原有路面结构层，利用水泥土的强度以及加筋板土工格栅钢塑格栅的加筋作用增强结构稳定性，分散路基受力，防止由于新老路地基强度不同而产生的不均匀差异性沉降。
