CONNECTION STRUCTURE OF COMPOSITE PILE AND CONSTRUCTION METHOD OF COMPOSITE PILE USING CHASER PILE

摘要

The present invention relates to a construction method of the synthetic pile connecting structure and synthesis of the pile used for the pile foundation.; The present invention is a concrete-based pile (2) in the synthesis pile (1) is configured as a coupling connection plate 3 to the head of concrete-based pile (2) is connected to a steel pipe pile (4) in the connection plate (3) the connecting plate 3 and the conventional welding by having plant ganggyeol the connecting plate 3, the bolt 6 and nut 7 steel pipe pile by using a fixture (4) in the combined brackets (5) connected to the in saves time compared to the connection method can be reduced by shortening the construction period and reduce the cost of construction and the standby time of the device.; The invention also stress concentration in the head of a concrete-based peg (2) by at pile driving the steel pipe pile (4) constituting the conventional synthetic pile (1) above wherein the inertia in the construction of the composite pile (1) by pile driving this occurs by concrete based ground plane for the pile (2) of the large connection plate (3) contact area of ​​the connecting plate 3 in order to improve the problem that the generated head injury is concrete based pile (2) of the cross-section center by using a pile driving auxiliary pile (8) which is located in the construction of composite piles (1) to generate equally a stress generated in the head region of the concrete pile type (2) to prevent damage to the concrete pile type (2).
