Application method for improving soil quality of saline-alkali soil in coastal area
The invention discloses an application method for improving soil quality of saline-alkali soil in a coastal area. The method comprises the following steps: arranging a flat layer on the top of a saline-alkali soil body, arranging a working cushion layer above the flat layer, arranging a drainage sand cushion layer above the working cushion layer, arranging a composite cloth film layer above the drainage sand cushion layer, and arranging an upper cushion layer and a backfill layer above the composite cloth film layer; and a film pressing groove is formed in one side of the working cushion layer. Through the arrangement of the leveling layer, the requirement for the flatness of the bottom of the soil layer is met, and multiple arrangements are conducted by combining stress and drainage of the leveling layer; through the edge closing arrangement of the sealing film, vacuum is formed, drainage is facilitated, and the precision of upper filling and stacking is guaranteed; an operation surface can be greatly provided for upper structure construction through the working cushion layer and the drainage sand cushion layer; the building application foundation treatment is partitioned, construction can be conducted according to the functions of the building application foundation, the use purpose of the building application foundation can be achieved through control of different stacking conditions, the working efficiency can be greatly improved, and the cost can be greatly reduced.
本发明公开了一种沿海地区盐碱地土质改良应用方法，含盐碱的土体顶部设置为平整层，在平整层上方设置有工作垫层、在工作垫层上方设置有排水砂垫层、在排水砂垫层上方设置有复合布膜层、设置于复合布膜层上方的上垫层和回填层；在工作垫层一侧设置有压膜沟。本发明通过平整层的设置，既保证了土层底部的平整度要求，又结合其受力和排水进行多重设置；通过密封膜收边设置，利于形成真空便于排水，和保证上部填充和堆载的精准度；通过工作垫层和排水砂垫层，可极大的为上部结构施工提供操作面；通过将建筑应用地基处理分区，既可以根据其功能分别施工，又可以通过不通的堆载条件控制，达到其使用目的，可极大的提高工作效率和成本。
