The invention relates to the technical field of steel pipe piles, in particular to a top closed type steel pipe pile which comprises an outer pipe and an inner pipe, the lower end of the outer pipe is closed, the inner pipe slides up and down in the outer pipe, a sliding sealing piece is arranged on the outer wall of the inner pipe and is in sliding connection with the inner wall of the outer pipe, and a supporting ring is arranged on the top of the inner pipe. The support ring is supported at the top opening of the outer pipe; and the sealing assembly is installed in the inner pipe, the sealing assembly is used for sealing the interior of the inner pipe and comprises a first sealing plate and a second sealing plate, a connecting rod is arranged between the first sealing plate and the second sealing plate, and the first sealing plate and the second sealing plate are both in threaded connection with the inner wall of the inner pipe. According to the device, the space between the outer pipe and the inner pipe can be in a negative pressure state, adsorption tension on the water surface is achieved, and the vertical uplift bearing capacity of the steel pipe pile is increased.
本发明涉及钢管桩技术领域，具体涉及一种顶部闭口式钢管桩，包括外管和内管，外管下端封闭，所述内管上下滑动在外管的内部，所述内管的外壁设置有滑动密封件，滑动密封件与外管的内壁滑动连接，所述内管的顶部设置有支撑环，所述支撑环支撑在外管的顶部开口处；封口组件，安装在内管的内部，所述封口组件用于对内管内部进行密封，包括第一封口板和第二封口板，所述第一封口板与第二封口板之间设置有连接杆，所述第一封口板和第二封口板均与内管的内壁螺纹连接。本发明中，可以使外管与内管之间的空间处于一个负压状态，对水面具有吸附的张力，增加钢管桩竖向抗拔承载力。
