A BRIDGE LIFTING APPARATUS AND BRIDGE LIFTING METHOD USING THE SAME

摘要

PURPOSE: A device and a method for elevating a bridge using the surrounding environment are provided to enlarge the lower area while minimizing the load carrying capacity of the pier foundation. CONSTITUTION: A device for elevating a bridge using the surrounding environment comprises a lower pulling support stand(10), a top pulling support stand(20), a guide member(30), a jack(50), and a supporting board(60). The lower pulling support stand is installed in the bridge pier circumference in order to be located at the lower part of a cross section(70) of the bridge pier. The top imprint support stand is installed at the circumference of the bridge pier in order to be positioned on the top of the cross section. The guide member is combined with one part of the lower pulling support stand and the top pulling support stand. The guide member guides the increased bridge pier not to be transmitted. The jack is installed between the lower pulling support stand and top pulling support stand to be fixed on the top of the lower pulling support stand. The jack lifts the top pulling support stand in order to increase the cut bridge pier. The supporting board is installed between the top pulling support stand and the lower pulling support stand elevated by the jack.
