Convex bucket foundation with ribbing in surface

The utility model relates to a surface convex bucket foundation with ribbing, including the steel drum main part, convex pleural region, wash port, base. Characterized by: at steel drum main part equipartition prefabrication all around pleural region, the shape of pleural region is the rectangle, and the bucket foundation base is located steel drum main part central point to be put, and two wash ports distribute along central symmetry. Utility model takes rib structure because of the surface has the arch, makes staving cross -section girth increase, increased with the area of contact on sand and soil layer, and then increased barrel basis vertical bearing capacity, can reduce displacement and the rotation under the horizontal loading simultaneously, further improve bucket foundation's stability. 本实用新型为种表面凸形带肋桶形基础，其中包括钢桶主体，凸形肋部，排水孔，基座。其特征是：在钢桶主体四周均布预制肋部，肋部的形状为长方形，桶形基础基座位于钢桶主体中心位置，两个排水孔沿中心对称分布。实用新型因表面具有凸起带肋结构，使桶体截面周长增加，增大了与沙土层的接触面积，进而增大了桶型基础竖向承载力，同时可以减小水平荷载作用下的位移和转动，进步提高桶形基础的稳定性。
