Paving structure of road culvert
The invention discloses a pavement structure of a road culvert. The paving structure comprises a soft soil base layer; the replacing and filling layer surrounds the outer side face of the culvert, is stacked in the area, not bearing the culvert, of the soft soil base layer and is used for filling building waste residues; the middle part of the rigid plate is covered between the soft soil base layer and the culvert, and the two ends of the rigid plate are located in the replacement filling layer; the geogrid is covered on the rigid plate; and the flexible material layer covers the top surface of the culvert. According to the technical scheme, the characteristic of high flexibility of the soft soil foundation can be utilized to reduce the pressure of the culvert top soil; due to the building waste residues, force transmitted by the two sides can be applied to the building waste residues, and the stress of the culvert top and the culvert side walls is reduced; the rigid plate can ensure uniform settlement of the culvert; the geogrids can enable the force of the culvert top to be better transmitted to the two sides, and it can be guaranteed that the culvert sinks within the allowable range. According to the technology, part of the soft soil foundation is reserved, the culvert top soil pressure and the culvert side soil pressure can be effectively reduced, construction is convenient, and the construction period can be shortened.
本申请公开了道路涵洞的铺装结构。该铺装结构包括：软土地基层；换填层，包围涵洞的外侧面并叠置在软土地基层非承载涵洞的区域，用以填入建筑废渣；一刚性板，中间部分覆于在软土地基层、涵洞之间，两端部分位于换填层内；一土工格栅，覆于刚性板上；柔性材料层，覆于涵洞的顶面。本技术方案中，能利用软土地基柔性大的特点，来减小涵顶土压力；建筑废渣可使得两侧传递得力均施加到建筑废渣上，使涵顶以及涵洞侧墙受力均减小；刚性板可保证涵洞均匀沉降；土工格栅可使得涵顶的力更好的向两侧传递并且可以保证涵洞在允许的范围内沉降。该技术将保留部分软土地基，不仅能有效减小涵顶土压力、涵侧土压力，并且具有施工便利，能缩短工期等特点。
