Premixed flow-state solidified soil foundation trench backfill construction method
The invention provides a premixed flow-state solidified soil foundation trench backfill construction method. The method comprises the steps of solidified soil preparation, foundation trench cleaning,gravel drainage ditch construction, formwork erecting, layered pouring, surface scraping treatment, field finished product protection, solidified soil maintenance and the like. The method is convenient and fast in construction process, economical, convenient in material obtaining, good in stability, high in compactness, good in self-sealing performance and impermeability, and short in constructionperiod, compared with a traditional backfill construction mode that a small excavator and a tamping machine are used for backfilling, chute backfilling is used, vibration is not needed, layered construction joint faces can be well combined without chiseling, construction joints cannot be formed, and the problems that in traditional backfill construction, the construction difficulty is large, thebackfill construction period is long, and the backfill quality is difficult to control are solved.
本发明提供了预拌流态固化土基槽回填施工工法，包括：固化土准备、基槽清理、碎石排水沟施工、模板支设、分层浇筑、表面刮平处理、现场成品保护和固化土养护等步骤，施工过程便捷，经济节约，取材方便，稳定性好，密实度高，自密性、抗渗性能好，施工周期短，相对传统回填施工中使用小型挖土机、打夯机进行回填的方式，使用溜槽回填，且无需振捣，分层施工结合面无需凿毛即可结合良好，不会形成施工缝，解决了传统回填施工存在的施工难度较大、回填工期较长、回填的质量难以控制的问题。
