Plateau cold and arid region strong alkali salinized soil roadbed construction method
The invention discloses a construction method for a strong-alkali saline soil roadbed in a plateau cold and arid region, belongs to the technical field of roadbed construction, and solves the problem that an existing construction method is not suitable for the strong-alkali saline soil roadbed in the plateau cold and arid region. The method comprises the steps that a site is cleaned; sand grains are selected to fill the bottom of the roadbed; the foundation with the remaining depth is subjected to bedding soil layer division; acid liquor is taken and mixed with the filling soil material, and lime is added into the filling soil material; filling of a first soil layer is conducted, specifically, the treated filling soil material is placed in the foundation, sand is taken to fill the top of the filling soil material and compacted, then cloud soil and rockwork continue to be filled on the upper layer, and filling of the first soil layer is completed; the remaining soil layer is filled in the same mode; paving asphalt on the surface layer. According to the method, the original soil material is acidized, so that the acid soil material can be effectively neutralized with the strong alkali salinized soil in the plateau cold and arid region, the compactness and compactness between the filled soil are guaranteed, and the stability of the foundation is effectively guaranteed.
本发明公开了一种高原寒旱区强碱盐渍土路基施工方法，属于路基施工技术领域，解决了现有施工方法不适用于高原寒旱区强碱盐渍土路基的问题。发明方法：对场地进行清理；选择砂粒，填补路基底部；将剩余深度的地基进行铺垫土层划分；取酸液，与填补土料进行混合，并在填补土料中加入石灰；进行第一层土层的填补：将处理后的填补土料置入地基内，取砂粒在填补土料顶部进行填充并压实，然后在上层继续填补云土与石方，完成第一层土层的填补；以同样的方式对剩余土层进行填补；在表层铺设沥青。本发明将原土料进行了酸化处理，使酸性土料能够与高原寒旱区强碱盐渍土壤进行有效中和，从而保证填补土壤之间的紧密度与紧实度，从而有效保证地基的稳固性。
