Road reconstruction and extension drainage ditch base treatment method
The invention discloses a road reconstruction and expansion drainage ditch base treatment method. The method comprises the steps that S1, an original drainage ditch of an original roadbed is removed; s2, after the two sides of the original drainage ditch extend by a certain distance, a foundation pit is excavated downwards, and steps are reserved every certain height; s3, the excavated foundation pit base is fully compacted; s4, the compacted foundation pit is backfilled with regenerated aggregates, and the backfilled regenerated aggregates are fully compacted; and S5, a layer of geogrid is laid on the fully-compacted regenerated aggregates, a lime soil cushion layer is backfilled above the geogrid to the ground line, and after the backfilled lime soil cushion layer is fully compacted, treatment of the original drainage ditch base is completed. The method is simple and high in operability, loss of natural resources is reduced, meanwhile, resource recycling of the regenerated aggregates is achieved, the manufacturing cost is low, compared with a traditional treatment mode, the innovativeness is high, and the economic benefits are improved while the construction efficiency is improved.
本发明公开了一种道路改扩建排水沟基底处治方法，包括步骤S1、对原路基的原排水沟进行拆除；步骤S2、在原排水沟的两侧各延伸一定距离后向下开挖基坑，并每隔一定高度预留一阶台阶；步骤S3、对开挖后的基坑基底进行充分压实；步骤S4、在压实后的基坑内回填再生粒料，并对回填的再生粒料进行充分压实；步骤S5、在充分压实后的再生粒料上铺设一层土工格栅，并在土工格栅上方回填灰土垫层至地面线，对回填后的灰土垫层进行充分压实后完成对原排水沟基底的处治。本发明方法简单，操作性强，减少了对自然资源的损耗，同时也实现了再生粒料的资源循环利用，造价低廉，相对于传统的处理方式，具有较高创新性，在提高施工效率的同时，也提高了经济效益。
