Vibration abatement type lifting device for replacing and repairing bridges for bridge support and its construction method applying computer control method

摘要

The present invention provides a vibration attenuation type lifting device for replacing and repairing a bridge support for a bridge and a construction method applied with a computer control method. According to the present invention, the vibration attenuation type lifting device for replacing and repairing a bridge support for a bridge prevents a hydraulic jack from deviating from a predetermined range on a vibration load due to passing of a vehicle or a load of an upper structure transferred to the hydraulic jack due to a dead load, a live load, or temperature change by the upper structure when and after the upper structure of a bridge is lifted until construction is completed. The vibration attenuation type lifting device for replacing and repairing a bridge support for a bridge also reduces stress or vibration without a slope and, therefore, can minimize transfer of the vibration or the stress to a lower structure or the upper structure. The vibration attenuation type lifting device for replacing and repairing a bridge support for a bridge enables safe and stable construction of replacement and repair of the bridge support. To achieve the purpose of the present invention, the vibration attenuation type lifting device for replacing and repairing a bridge support for a bridge comprises: an upper ground contact pressure panel including the hydraulic jack and an elastic pad; a lower ground contact pressure panel; and a ground contact pressure plate. Therefore, the vibration attenuation type lifting device for replacing and repairing a bridge support for a bridge minimizes damage to the lower structure due to the vibration or the stress of the vibration load and can obtain high safety and the effect of obtaining long usage periods.
