Premixed flow state solidified soil and gravel stirring composite backfill soil construction technology
The construction technology comprises the following steps that S1, soil materials are prepared, the content of organic matter is not larger than 5%, and the particle size of the organic matter is not larger than 50 mm; s2, gravel material preparation, wherein the particle size is not larger than 50 mm; s3, checking and storing a curing agent; s4, mixing the composite solidified soil; s5, solidified soil transportation, wherein solidified soil is transported through a tank car or pumped and poured through an automobile pump; s6, layered backfilling of solidified soil: layered pouring is carried out during pouring, manual auxiliary slicking is carried out in the pouring process, inspection is carried out corresponding to an elevation control line on the side wall of the pit (groove), it is guaranteed that each pouring layer is basically horizontally carried out, and foundation trench backfilling is continuously carried out; s7, construction sampling; after optimization and improvement of the premixed flow state solidified soil and gravel stirring composite backfill soil, the strength is greatly improved and can reach 5-20 Mpa, and the backfill soil is good in compactness and has good self-sealing performance, impermeability and flowability.
本发明公开一种预拌流态固化土与碎石搅拌复合回填土施工技术，包括如下步骤：S1、土料准备：有机质含量不大于5%，其颗粒粒径不大于50mm；S2、碎石料准备：颗粒粒径不大于50mm；S3、固化剂检查与存储；S4、复合固化土拌和流程；S5、固化土运输：固化土采用罐车进行运输或采用汽车泵送进行泵送浇筑；S6、固化土分层回填：浇筑时分层浇筑，在浇筑过程中应人工辅助刮平，与坑（槽）边壁上的标高控制线对应检查，保证每一浇注层基本水平进行，基槽回填连续进行；S7、施工取样；S8、找平与验收，预拌流态固化土与碎石搅拌复合回填土优化改进后，强度大大提升，可达到5～20Mpa，且密实度好，具有良好的自密性、抗渗性和流动性。
