Enclosure structure for soft soil foundation and construction method thereof
The invention discloses an enclosure structure for a soft soil foundation and a construction method thereof.The enclosure structure for the soft soil foundation comprises modified prestressed anchoring rods and a retention wall arranged in soil on the periphery of a foundation pit, and the retention wall divides the foundation into a foundation pit pre-buried area and a water retaining reinforcing area from inside to outside in sequence; a first metal net layer, a reinforcing layer, a second metal net layer and a backfilling layer are sequentially arranged in the foundation pit pre-buried area from outside to inside, the retention wall is formed by meshing a plurality of sets of plain cement soil mixing piles perpendicular to the bottom of a foundation pit in pairs, and the modified prestressed anchoring rods penetrate through gaps formed between the adjacent plain cement soil mixing piles. The modified prestressed anchoring rod comprises an anchoring sleeve until the anchoring section of the modified prestressed anchoring rod is located in the water retaining reinforcing area; the structure has the effect of reinforcing soil on the outer side of the retention wall, and the stability of the retention wall is greatly improved.
本发明公开了一种用于软土地基的围护结构及其施工方法，该用于软土地基的围护结构包括改性预应力锚固杆和设于基坑外围土壤内的挡水墙，挡水墙将地基由内至外依次划分成基坑预埋区域和挡水加固区域，基坑预埋区域由外而内依次设有第一金属网层、加固层、第二金属网层和回填层，挡水墙由若干组垂直于基坑底部的素水泥土搅拌桩两两之间相互咬合而成，改性预应力锚固杆贯穿相邻素水泥土搅拌桩之间形成的缝隙，直至改性预应力锚固杆的锚固段位于挡水加固区域内，改性预应力锚固杆包括锚固套筒；本发明具有加固挡水墙外侧土壤的作用，大大增强挡水墙的稳定性。
