Roadbed soft foundation compaction treatment construction method
The invention discloses a roadbed soft foundation compaction treatment construction method, and relates to the technical field of roadbed construction, and the roadbed soft foundation compaction treatment construction method comprises the following steps: pretreating and compacting an original earth surface; after compacting, measuring and setting out; using coarse-grained soil for roadbed filling, performing filling in a longitudinal segmentation and horizontal layering mode during filling, wherein the filling thickness of a first layer is 600-700 mm after loose laying; roughly leveling by using a bulldozer, and finely leveling by using a land leveler until no obvious unevenness exists; the water content of the filling layer is controlled to be +/-2% of the optimal water content before compaction, a vibratory roller with the self weight larger than or equal to 32 T is used for rolling, static pressure is conducted once again when the compaction degree is 93%, and compaction treatment of the roadbed soft foundation is completed. By means of the construction method, the problem that the bearing capacity of the soft foundation of the roadbed is weak can be effectively solved, the foundation spring phenomenon caused by thin-layer rolling on the soft foundation in a traditional method is avoided, the occurrence of diseases such as differential settlement of the roadbed in the later period is effectively reduced, the service life of the roadbed is prolonged, and economic benefits are improved.
本发明公开了一种路基软基压实处理施工方法，涉及路基施工技术领域，包括：对原地表进行预处理并压实；压实后进行测量放样；采用粗粒土进行路基填筑，填筑时采用纵向分段、水平分层的方式进行填筑，第一层填筑厚度为松铺600‑700mm；用推土机粗平后使用平地机精平至无显著凹凸；压实前控制填筑层的含水量为最佳含水量的±2%，用自重≥32T振动压路机进行碾压，碾压至压实度为93%时再静压一遍，完成路基软基的压实处理。采用本发明的施工方法能够有效解决路基软基承载力偏弱的问题，免了传统方法中对软基进行薄层碾压造成地基弹簧现象，有效减少了后期路基不均匀沉降等病害的发生，提高了路基使用寿命及经济效益。
