Suction bucket foundation for performing vacuum preloading reinforcement on soil plug in bucket
The invention discloses a suction bucket foundation for vacuum preloading reinforcement of a soil plug in a bucket. The suction bucket foundation comprises an inner bucket, an outer bucket covering the inner bucket, a supporting plate, a connecting ring, a filter membrane and an air exhaust hole. The bottom ends of the inner barrel and the outer barrel are connected through a connecting ring; an exhaust hole is formed in the top of the outer barrel; the multiple supporting plates are arranged in the circumferential direction of the outer wall of the inner barrel at intervals and fixedly connected with the outer wall of the inner barrel. The filter membrane is uniformly laid and fixed on the outer wall of the inner barrel; the outer barrel covers the inner barrel and the supporting plate, a gap is reserved between the outer barrel and the inner barrel, and the gap forms a drainage channel. Vacuum preloading reinforcement of the soil plug in the suction bucket can be achieved, the soil body within the depth range of the inner bucket is under the vacuum consolidation pressure, drainage consolidation of the soil plug is promoted, the strength of the soil body of the soil plug is improved, and therefore the uplift bearing capacity of the suction bucket foundation is improved.
本发明公开了一种对桶内土塞进行真空预压加固的吸力桶基础，包括内桶、罩设于内桶外的外桶、支撑板、连接环、滤膜以及抽气孔；内桶和外桶的底端通过连接环相连；外桶的顶部设有抽气孔；多块支撑板沿内桶的外壁周向间隔设置，且与内桶的外壁固定连接；滤膜均匀铺设并固定在内桶的外壁上；外桶罩设在内桶和支撑板的外部，且外桶和内桶之间留有间隙，间隙形成排水通道。本发明能够实现吸力桶内土塞的真空预压加固，内桶深度范围内的土体处于真空固结压力之下，促进土塞的排水固结，提高土塞土体强度，从而提高吸力桶基础的抗拔承载力。
