Embodiment 1

[0032] see Figure 1-7 , the present invention provides the following technical solutions: a prestressed steel support pile, including a support pile 1, one side of the support pile 1 is provided with an H-shaped butt beam 2, and the surface of the H-shaped butt beam 2 is provided with several adjustment mechanisms 3. The inner wall of the H-shaped butt beam 2 is fixedly connected with a number of support mechanisms 4, and the adjacent support mechanisms 4 are fixedly connected with a strengthening mechanism 5, and two adjacent H-shaped butt beams 2 are fixedly connected by a shaping mechanism 6.

[0033] In this embodiment: both ends of the support pile 1 are fixedly connected with clamping blocks 11, the surface and back of the support pile 1 are provided with installation grooves 12, and one side of the support pile 1 is provided with a docking groove 13. The other side of the support pile 1 is fixedly connected with a butt column 14, and the butt column 14 extends from bot...

Abstract

The invention provides a prestressed steel support pile and an installation method, including a support pile, one side of the support pile is provided with an H-shaped butt beam, the surface of the H-shaped butt beam is provided with several adjustment mechanisms, and the inner wall of the H-shaped butt beam There are a number of support mechanisms fixedly connected, and a strengthening mechanism is fixedly connected between adjacent support mechanisms, and two adjacent H-shaped butt beams are fixedly connected by a shaping mechanism. The opening of the docking groove greatly reduces the connection gap between the adjacent support piles, which solves the problem of excessive gaps between the traditional steel sheet piles. The force of the supporting rod plays the role of sharing the force for the support rod, and the shaping rods arranged at the four diagonals connected by the H-shaped butt beam play a role in shaping the H-shaped butt beam.

Description

technical field [0001] The invention relates to the technical field of support piles, in particular to a prestressed steel support pile. Background technique [0002] Supporting piles are mainly piles that bear lateral thrust. They are generally used for foundation pit support, slope support, and landslide control. They bear horizontal soil pressure or landslide thrust, and generally require higher reinforcement than foundation piles that bear vertical forces. It is also often used with anchor rods (cables). The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane size. When excavating the foundation pit, in order to prevent the foundation pit from collapsing, it is necessary to carry out foundation pit support treatment. When supporting the foundation pit, the foundation pit will be supported by support piles. When constructing support piles, the measurement and positioning will be carried out firs...
