Red mudstone gravel soil waterproof roadbed construction method
The invention relates to the technical field of roadbed waterproof construction, in particular to a red mudstone gravel soil waterproof roadbed construction method which comprises the following steps: A) technical preparation work before roadbed backfilling; b) surveying and setting out, and cleaning and compacting the surface of the original ground; c) excavating and backfilling a roadbed, and building steps in layers at a filling and excavating junction; d) half-filling and half-digging roadbed construction; e) paving a geogrid; and F) constructing two waterproof layers on the top surface of the roadbed. According to the construction method, the water-resisting layer is arranged on the roadbed, the water-resisting layer is filled with the red mudstone crushed gravel powder and the water to form a compact layer, the water-resisting effect is good, and after the roadbed is laid at a proper position, the situation that the moisture content of the top of the roadbed is increased under the capillary and pumping action of underground water can be prevented; the geogrid is used for reinforcement, the adverse effect caused by rising of the water content of the soft rock roadbed due to rainfall in the rainy season is reduced, secondary excavation and airing in the later period are avoided, and the geogrid and the geogrid can jointly achieve the reinforcement effect.
本发明涉及路基防水施工技术领域，具体是一种红泥岩碎砾土防水路基施工方法，包括如下步骤：A）路基回填前的技术准备工作；B）测量放线、原地面清表与压实；C）路基开挖与回填、填挖交界处分层修筑台阶；D）半填半挖路基施工；E）铺筑土工格栅；F）路床顶面两层防水层施工。本发明中，在路基上设置隔水层，且隔水层采用红泥岩碎砾土压碎石粉和水充填形成致密层，隔水效果好，在适当位置铺设后，可防止地下水在毛细和泵吸作用下造成路基顶部含水率升高，在路基工作区内铺设多层土工格栅，使用土工格栅进行补强，减小了因雨季降雨软岩路基含水量升高造成的不利影响，避免了后期二次开挖晾晒等，且与土工格栅可共同起到加筋的效果。
