Embodiment Construction

[0012] In the figure, the foundation pile automatic fast spiral tooth-shaped docking structure includes the upper foundation pile 1 to be connected, the frustum teeth 2, the external thread frustum 3, the internal thread frustum groove 4, the cone wall teeth 5 and the lower foundation pile to be connected. Pile 6; at the end of the lower end of the foundation pile 1 to be connected on the upper part, an externally threaded conical frustum 3 with raised threads is axially provided, and the outer threaded conical frustum 3 is evenly distributed around the upper end of the externally threaded conical frustum 3. The frustum teeth 2 and the frustum alveolar grooves of the conical frustum 3 are spaced in the same helical direction as the threads on the threaded conical frustum 3. At the end of the lower end to be connected to the upper end of the foundation pile 6, an inner thread that matches the external threaded conical frustum 3 is axially provided. Threaded frustum of conical ...

Abstract

The invention relates to an automatic rapid helical tooth shape abutting structure of a foundation pile. An external-thread circular truncated cone which protrudes to extend and is provided with bulged threads is axially arranged on the lower end of an upper to-be-abutted foundation pile, spaced frustum teeth and frustum tooth sockets of which the screwing direction is coincident with that of threads on the external-thread circular truncated cone are uniformly distributed around the upper end of the external-thread circular truncated cone, an internal-thread circular truncated cone groove which is matched and coincides with the external-thread circular truncated cone is axially formed in the upper end of a lower to-be-abutted foundation pile, conical wall tooth sockets which are in tooth shape abutting with the frustum teeth are uniformly distributed around the upper end of the internal-thread circular truncated cone groove, and the conical wall tooth sockets and conical wall teeth are staggered at intervals; during abutting, quick-drying high-strength cement slurry is applied to the outer parts of the external-thread circular truncated cone and the frustum teeth and the inner parts of the internal-thread circular truncated cone groove and the conical wall tooth sockets. The automatic rapid helical tooth shape abutting structure of the foundation pile has the advantages of simple structure, low cost, time saving, labor saving, stability and reliability, and the automatic rapid helical tooth shape abutting of the foundation pile can be realized.

Description

technical field [0001] The invention relates to a butt joint structure of foundation piles, in particular to an automatic fast spiral tooth form butt joint structure of foundation piles which can be automatically and quickly joined. Background technique [0002] The pile foundation is a force-transmitting member with a certain rigidity and bending resistance that transmits the load of the superstructure to the foundation. It is an ancient and common form of deep foundation. Compared with other foundation forms, pile foundation has the characteristics of high bearing capacity, small and uniform deformation, low material consumption, and high degree of construction mechanization. It can be applied to almost all kinds of geological conditions and various types of engineering construction. It is widely used in industrial and civil construction engineering. At present, due to some geological reasons and different bearing capacities, it is often necessary to connect several found...
