Nested pile casing used for pile foundation construction under underwater and soft foundation geologic conditions
The invention relates to a nested pile casing used for pile foundation construction under underwater and soft foundation geologic conditions. The pile casing mainly solves the technical problems that an existing pile casing is serious in steel waste and high in construction cost. According to the technical scheme, the nested pile casing used for pile foundation construction under the underwater and soft foundation geologic conditions comprises a plurality of sections of outer pile casings, a plurality of sections of thin-wall lining pile casings and a sealing gasket, the plurality of sections of outer pile casings are connected into the outer pile casings through bolts, and the plurality of sections of thin-wall lining pile casings are connected into the sealing gasket. The thin-wall lining pile casings are fixedly connected into the disposable lining pile casing through welding, the disposable lining pile casing is arranged in the outer pile casing, and the sealing gasket is arranged between the outer wall of the disposable lining pile casing and the inner wall of the outer pile casing and located at the bottom of the inner wall of the outer pile casing. The method has the advantages that a large amount of steel can be saved, and the construction cost is reduced.
本发明涉及一种水下及软基地质条件下桩基施工使用的嵌套护筒。本发明主要解决现有护筒存在的浪费钢材严重和施工建设成本高的技术问题。本发明采用的技术方案是：一种水下及软基地质条件下桩基施工使用的嵌套护筒，其包括若干节外护筒、若干节薄壁内衬护筒和密封垫，所述若干节外护筒通过螺栓连接成外护筒，所述若干节薄壁内衬护筒通过焊接固定连接成一次性内衬护筒，所述一次性内衬护筒设在外护筒内，所述密封垫设在一次性内衬护筒外壁与外护筒内壁之间并位于外护筒内壁的底部。本发明具有能节约大量钢材和降低施工建设成本的优点。
