In general, one of the methods of reinforcing the ground when constructing a building or a bridge, or when constructing a structure on a soft ground, a steel pipe pile ground reinforcement method for reinforcing the ground by driving steel pipe piles at regular intervals can be seen.

The steel pipe pile ground reinforcement method is to lay the foundation by hammering the steel pipe to the ground, hammering a plurality of vertically connected bars and band bars on the upper part of the steel pipe, placing horizontal hooked bars on it, and then placing the expanded concrete on it. It can be seen that the ground is reinforced.

The present invention is to provide a head reinforcement structure to reinforce the head of the steel pipe pile by reinforcing a plurality of vertical connecting bars to the steel pipe pile to reinforce the ground.

There are various methods of reinforcing the head of a conventional steel pipe pile.

As an example, there is a method of installing the cover plate on the top of the steel pipe pile by welding a reinforcing plate on the inner circumferential surface of the steel pipe pile, welding the cover plate to the top of the steel pipe pile, and welding the reinforcement around the cover plate.

This method not only increases the labor and production cost because the worker has to weld the cover plate and the rebar in the field, but also the heat of welding can cause deformation, cracking, tissue weakening and corrosion of the weld. Due to this, the welding can be eliminated, and it is vulnerable to the vertical load, which causes the failure of the structure.
