Composite reinforced light soil retaining wall roadbed integrated structure and construction method
The invention relates to a composite reinforced light soil retaining wall roadbed integrated structure and a construction method, and belongs to the technical field of road engineering design and construction. The composite reinforced light soil retaining wall roadbed integrated structure comprises a light retaining wall, a light roadbed and geogrids; the light retaining wall is formed by buildinga plurality of lateral light building blocks, the light roadbed is formed by pouring a plurality of light roadbed filler layers in a layered mode, a layer of the geogrids is arranged between every two adjacent light roadbed filler layers, and the lateral light building blocks and the light roadbed filler layers are made of foam light soil; and except the topmost layer, a certain length is reserved at the end of each layer of geogrid, and is used for reversely wrapping next newly-built lateral light building blocks from bottom to top and is connected with the next layer of geogrids. The lightretaining wall, the light roadbed and the geogrids are combined into the integrated composite structure, the light retaining wall and the light roadbed jointly bear lateral deformation caused by external loads, the geogrids can provide lateral constraint force, and the integrated structure has good deformation resistance.
本发明涉及一种复合加筋轻质土挡土墙路基一体化结构及施工方法，属于道路工程设计及施工技术领域，包括轻质挡土墙、轻质路基和土工格栅；轻质挡土墙由多个侧向轻质砌块砌筑而成，轻质路基由多层轻质路基填料层分层浇筑而成，相邻两层轻质路基填料层之间设置一层土工格栅，侧向轻质砌块和轻质路基填料层均采用泡沫轻质土制成；除最顶层外，每层土工格栅的端部均预留出一定的长度，用于从下往上反包接下来新砌筑的侧向轻质砌块，并与下一层土工格栅连接。本发明将轻质挡土墙、轻质路基和土工格栅结合成一个整体的复合结构，轻质挡土墙和轻质路基共同承担外荷载引起的侧向变形，且土工格栅可以提供侧向约束力，一体化结构具有良好的抗变形能力。
