Automatic and fast spiral tooth-shaped butt joint structure of foundation piles

Abstract

An automatic fast spiral tooth-shaped butt joint structure for foundation piles. At the end of the lower end of the foundation pile to be connected on the upper part, there is an externally threaded conical truncated protruding and extending axially, and the upper end of the externally threaded conical truncated is uniformly distributed with threads Conical frustum teeth and frustum tooth sockets at intervals with consistent rotation direction, at the end of the upper end of the pile to be connected to the lower part, there is an internal thread conical groove that matches the external thread conical frustum axially, and the internal thread conical frustum Around the upper end of the groove, there are evenly distributed conical wall alveolar butt joints with the teeth of the frustum of the cone, and the interval between the alveolar of the conical wall and the teeth of the conical wall is staggered; The interior of the platform groove and the tapered alveolar are coated with quick-drying high-strength cement slurry. The automatic fast spiral tooth form butt joint structure of foundation piles is simple in structure, low in cost, saves time and trouble, is stable and reliable, and can realize automatic rapid spiral tooth form butt joint of foundation piles.

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...
