An automatic fast rotating butt joint structure of foundation piles. At the end of the lower end of the foundation pile to be connected on the upper part, there is an extended conical truncated axially, and the wall of the lower end of the conical truncated section is provided with a threaded section, and the conical truncated ring groove is opened. There is a conical frustum grouting opening, and a conical frustum grouting channel is opened downward along the track of the threaded section; at the end of the lower part to be connected to the upper end of the foundation pile, a threaded cone matching the conical frustum is axially provided. Frustum groove, the inner upper part of the threaded conical frustum groove has a conical groove grouting opening that matches the conical frustum grouting opening, and the inner wall of the threaded conical frustum groove is evenly opened with a cone wall that matches the conical frustum annular groove Annular groove; when docking, the outside of the frustum of the cone and the inside of the groove of the threaded frustum of the cone are coated with quick-drying high-strength cement slurry. The automatic fast-rotating docking structure of foundation piles is simple to operate, saves time and effort, and is low in cost, and can realize automatic fast-rotating docking.
Description
technical field [0001] The invention relates to a butt joint structure of foundation piles, in particular to an automatic fast rotation butt joint structure of foundation piles which can be automatically and quickly rotated butt joint. 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 fo...
