Vacuum combined preloading sand-free cushion semi-fluid solidified soil construction method
The invention discloses a vacuum combined preloading sand-cushion-free semi-fluid solidified soil construction method, which adopts semi-fluid solidified soil to replace a vacuum combined preloading sand cushion on a film for solidified soil construction, that is to say, a soil body is in a fluid state during manufacture and construction of the solidified soil, and the poured soil body is in a semi-fluid state during pouring. And the flowability is lost in a short time and the intensity is gradually generated. High-strength solidified soil is formed on the sealing film through the semi-flow solidified soil construction technology, a sand cushion layer on the film is replaced, the reliability of the later strength of the solidified soil is further guaranteed while the construction convenience of the solidified soil is guaranteed, and the method has wide application prospects in the field of blow-filling soft soil through vacuum combined surcharge preloading treatment.
本发明公开了一种真空联合堆载预压无砂垫层半流态固化土施工方法，采用半流态固化土替代真空联合堆载预压膜上砂垫层进行固化土施工，即在固化土制作、施工时土体呈现流动态，浇筑时、浇筑后的土体呈现半流态，并在短时间内失去流动性且逐渐产生强度。本发明采用半流态固化土施工技术在密封膜上形成较高强度的固化土，替代膜上砂垫层，在保证固化土施工便捷性的同时，更保证固化土后期强度的可靠性，在真空联合堆载预压处理吹填软土领域具有广阔的应用前景。
