METHOD FOR ENHANCING BEARING POWER OF EXISTING BRIDGES USING THE A PILE

摘要

A method for increasing the bearing capacity of the existing bridge foundation is provided, which increases bearing capacity of the in-situ ground. A method for increasing the bearing capacity of the existing bridge foundation comprises: a step of installing a plurality of guide pipes at the constant interval around the circumference of the guide mold; a step of installing a punched steel pile(30) to the ground by being guided by the guide pipe; a step of disjointing the guide form and guide pipe in the bridge post; a step of improving bearing capacity by injecting drug into the in-situ ground; a step of forming a form by installing a form panel(40) to surround the outer side of steel piles; a step of installing a reinforcement structure(50) inside the mold; and a step of pouring and curing concrete.
