Abstract

The utility model relates to a historic building foundation overall tray shock insulating and reinforcing structure which comprises static pressure piles, directional drilling steel pipe concrete beams and shock insulation pads. The static pressure piles are arranged on the outer side of an existing historic building, the directional drilling steel pipe concrete beams horizontally penetrate through the bottom of the foundation of the existing historic building, the beams, the piles and the shock insulation pads arranged between the beams and the piles form new n-shaped shock insulation foundation frames of the existing historic building in the longitudinal direction, and the n-shaped shock insulation foundation frames are connected through connection beams to form into a whole to form an overall building shock insulation foundation system. Connection between the steel pipe concrete beams and the upper original foundation is guaranteed through necessary anchor rods. The steel pipe beams bear all the vertical load of the original building and the load of indoor soil and structures on the bottom of the foundation. The steel pipe concrete beams are filled with plain concrete after directional drilling to form an integration supporting platform. The steel pipe beams are supported by the piles at the two ends through the shock insulation pads, and in earthquakes, the shock insulation pads greatly reduce various influences of earthquake force on the upper building.
