The invention discloses a steel pipe pile supporting structure which comprises a steel pipe pile sinking in a pile hole, the pile hole is annular, an outer mud layer is arranged between the steel pipe pile and an external soil body, the outer mud layer is in a barrel shape extending around the outer wall of the steel pipe pile, and an inner mud layer is arranged between the steel pipe pile and an internal soil body. The inner slurry layer is in a barrel shape extending around the inner wall of the steel pipe pile. The pile hole is formed by adopting a construction process of a slurry retaining wall, and the outer slurry layer and the inner slurry layer are both formed by slurry reserved in the pile hole. The invention further discloses a construction method of the steel pipe pile supporting structure. The pile hole is formed by adopting a slurry retaining wall construction process, the inner slurry layer and the outer slurry layer are formed by utilizing slurry in the pile hole, when the steel pipe pile is recycled, the steel pipe pile is rotated, the structural stability of the inner slurry layer and the outer slurry layer can be destroyed and liquefied, the bonding force between the steel pipe pile and a soil body is reduced, and the soil body inside and outside the pile can be kept underground during pile pulling; and holes are avoided.
本发明公开了一种钢管桩支护结构，其包括下沉在桩孔内的钢管桩，该桩孔呈环形，在钢管桩与外部土体之间具有外泥浆层，该外泥浆层呈环绕钢管桩的外壁延伸的筒状，在钢管桩与内部土体之间具有内泥浆层，该内泥浆层呈沿绕钢管桩的内壁延伸的筒状；该桩孔采用泥浆护壁的施工工艺形成，该外泥浆层和内泥浆层均由桩孔内所保留的泥浆形成。本申请还公开了钢管桩支护结构的施工方法。本申请采用泥浆护壁的施工工艺形成桩孔，利用桩孔内的泥浆来形成内泥浆层和外泥浆层,当回收钢管桩时，转动钢管桩，即可破坏内外泥浆层的结构稳定性并液化，降低钢管桩与土体的粘结力，能够在拔桩时使桩内外的土体保持在地下，避免留下空洞。
