Sand filling roadbed construction method for municipal roads
The invention discloses a sand filling roadbed construction method for municipal roads. According to the method, fine sand is used as a main supporting body and high-quality soil is used as the last layer of supporting body for layered backfilling; after combination of backfill material water content control, loose paving thickness and rolling compaction times control and compaction mechanical properties, local resources are utilized during roadbed construction in a sandy soil area, sandy soil is used as a backfill material for roadbed construction, so that resources are saved, the construction period is shortened, and the overall stability of a roadbed is improved. Compared with the prior art, the fine sand is used as a main supporting body for layered backfilling and local resources areused for roadbed construction; materials are obtained nearby, so that the construction cost is reduced and the construction period is shortened; high-quality soil is used as an upper supporting body for layered backfilling, so that fine sand water losses are effectively prevented, the roadbed stress integrity is guaranteed, and the roadbed overall stability is improved.
本发明公开了一种市政道路填砂路基施工方法，该方法结构采用细砂作为主要支承体，优质土作为最后一层支承体进行分层回填，通过对回填材料含水量控制，松铺厚度与碾压遍数控制及压实机械性能的组合，从而在砂土地区进行路基施工时利用当地的资源，用砂土作为回填材料进行路基施工，不但节省了资源，缩短了工期，同时还提升了路基的整体稳定性。相对现有技术，本发明采用细砂作为主要支承体进行分层回填，利用当地的资源进行路基施工，就近取材，降低了工程造价，缩短了施工工期，用优质土作为上部支承体进行分层回填，有效防止细砂水分散失，保证路基受力的整体性，提升路基的整体稳定性。
