The invention relates to an enclosure structure for a soft soil foundation and a construction method of the enclosure structure. The enclosure structure comprises a plurality of steel sheet piles vertically arranged around a foundation pit to be formed; one end of the supporting pile is fixed to the steel sheet pile, and the other end of the supporting pile extends in the direction close to the foundation pit to be formed; the ring beam is formed on the ground along the steel sheet piles in a pouring mode, and parts of the ends, close to the steel sheet piles, of the supporting columns are embedded in the ring beam. The problem that foundation pit construction in a soft soil foundation is difficult is solved, the mode that the steel sheet piles are combined with the inclined supporting piles is utilized, the construction period can be shortened, the water stopping effect can be improved, good economic benefits are achieved, the construction quality is guaranteed, and potential safety hazards are reduced.

本发明涉及一种用于软土地基的围护结构及其施工方法，包括：竖直设置于待形成的基坑的周围的若干钢板桩；倾斜设置且一端固定于钢板桩的支撑桩，该支撑桩的另一端向靠近待形成的基坑的方向延伸；以及沿钢板桩浇筑形成于地面的圈梁，支撑柱靠近钢板桩的端部有部分埋设于圈梁内。解决了在软土地基中基坑施工较为困难的问题，利用钢板桩结合斜向支撑桩的方式，不仅能够缩短施工工期，还能提升止水效果，具有良好的经济效益，保证施工质量，减少安全隐患。
