Abstract

The invention discloses a multi-wing-sheet pile structure applicable to a soft soil foundation and a construction method. By means of the multi-wing-sheet pile structure applicable to the soft soil foundation and the construction method, the problem that existing pile forms such as cast-in-place piles or prefabricated tubular piles or sheet piles are not good in sedimentation reduction effect in the soft soil foundation can be solved. The multi-wing-sheet pile structure has the beneficial effect that bending resistance and torsion resistance of the pile structure are improved. According to thescheme, the multi-wing-sheet pile structure applicable to the soft soil foundation comprises three or more inner wing sheets and outer wing sheets, wherein the number of the outer wing sheets is theintegral multiples that of the inner wing sheets; the three inner wing sheets are arranged in the Y form; every two outer wing sheets are connected with the end of the corresponding inner wing sheet,and every two outer wing sheets and the corresponding inner wing sheet are arranged in the Y form; and the multi-wing-sheet pile structure is in rotary arrangement along the lower end points of the Yforms and is in a Y shape or a snowflake shape, and grouting guide pipes are longitudinally arranged at the ends of the inner wing sheets.

Description

technical field [0001] The invention relates to the field of pile foundation construction, in particular to a multi-wing sheet pile structure suitable for soft soil foundations and a construction method, and a multi-wing sheet pile structure suitable for soft soil foundations. Background technique [0002] Soft soil foundations are widely distributed in the coastal and southern regions. As the height and volume of buildings on soft soil foundations continue to increase, the problem of uneven settlement of buildings and structures has gradually become prominent. The settlement or excessive settlement difference will cause unfavorable To recover from damage, desaturation becomes increasingly important. The existing cast-in-situ piles, prefabricated pipe piles or sheet piles have insufficient single pile bearing capacity in soft soil foundations, and the settlement of the pile body is too large, and the settlement reduction effect needs to be improved. The adverse consequences...
