End buckle type prefabricated concrete anti-pulling pipe pile mechanical connection joint

Abstract

The invention discloses an end buckling type prefabricated concrete anti-pulling pipe pile mechanical connection joint which comprises key grooves formed in the ends of prefabricated pipe piles, end plates arranged at the ends of the prefabricated pipe piles, bony connecting pieces used for connecting the upper prefabricated pipe pile and the lower prefabricated pipe pile and anti-sliding blocks. The bony connecting piece penetrates through a large-head hole in an arc-shaped large-small-head long round hole in an end plate at one end of the lower-section prefabricated pipe pile to enter a key groove of the lower-section prefabricated pipe pile, and the bony connecting piece is moved to the position of a small-head hole in the arc-shaped large-small-head long round hole. And the fixed bony connecting piece is inserted into a large-head hole of the arc-shaped large-small-head long round hole of the end plate at the end part of the upper-section prefabricated pipe pile, and the pile body of the upper-section prefabricated pipe pile is rotated, so that the end buckles of the upper-section prefabricated pipe pile and the lower-section prefabricated pipe pile are fastened. The connection problem of the prefabricated concrete pipe piles can be solved, the structure is simple, installation is convenient, force transmission is reliable, it can be guaranteed that the upper pile and the lower pile have the good co-working performance, and connector safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete pipe piles in construction engineering, and in particular relates to an end-buckle type prefabricated concrete pullout-resistant pipe pile mechanical connection joint. Background technique [0002] The prefabricated concrete pipe pile is formed by the centrifugal method, and the excess water in the concrete is thrown out due to the centrifugal force, so the concrete is dense, high in strength, strong in resistance to groundwater and other corrosion, and has low production cost, saving steel, environmental protection, reliable quality, The characteristics of simple construction and low technical difficulty are widely used in the anti-floating design of basements of industrial and civil buildings. In the construction process of precast concrete uplift pipe piles, the prefabricated piles are generally multi-section piles, which need to be driven or pressed into the soil layer by sectio...
