Connection structure of composite pile and pile driving assistant pile for construction of composite pile

摘要

The present invention relates to the connection structure of the composite pile used in the pile foundation and the anti-stearing pile for the construction of the composite pile.;The present invention is a concrete pile (2) in the composite pile (1) consisting of a connecting plate (3) is coupled to the head of the concrete pile (2) and a steel pipe pile (4) connected to the connecting plate (3) Conventional welding by the steel plate pile (4) by using the fasteners of the bolt (6) and the nut (7) to the coupling bracket (5) connected to the connecting plate (3) and the connecting plate (3) in the factory Compared to the connection method, work time can be shortened and construction time can be shortened, and waiting time of equipment can be shortened and construction cost can be reduced.;In addition, the present invention stress concentration on the head of the concrete pile (2) by the driving force when driving the steel pipe pile (4) constituting the upper portion of the existing composite pile (1) in the construction of the composite pile (1) by driving In order to improve the problem that the head damage of the concrete pile (2) occurs, the ground area for the connecting plate (3) is large and the ground plane for the connecting plate (3) is the center of the cross section of the concrete pile (2) By constructing the synthetic pile 1 by using the anti-steer auxiliary pile 8 located in the stress generated in the head of the concrete pile 2 evenly to prevent the breakage of the concrete pile (2).
