摘要
The present invention can be temporarily passed by vehicles and passers-by when dismantling existing bridges over obstacles such as seas, rivers and valleys to install new bridges or when using existing bridges for maintenance of existing bridges. It relates to a method of installing temporary bridges to be installed.;Steel pipe column position maintaining device is installed so that a pair of steel pipe pillars can be installed on both sides of the bridge where the bridge is to be installed and the steel pipe column vents that can support the bridge structure on the bridge installed on one side can be installed at both sides. After installation, the steel pipe pile penetrates the steel pipe pile formed in the steel pipe column position maintaining device, and then the steel pipe pile is installed by using a driving machine to install a steel pipe pillar vent, and then the steel pipe cap installed in the extrusion guide device on the steel pipe pillar vent. Install an extrusion guide device by covering the extruder, install an extrusion device on the shift, and contact the mold, which is the cross-linked upper structure, with one end of the extrusion hydraulic jack installed in the extrusion device, and then exert the extrusion force on the extrusion hydraulic jack. The extrusion guide device while extruding the mold, which is a cross-linked upper structure, in the pressure direction The lower portion of the mold forming the cross-linked upper structure is placed into the guide installed in pairs at regular intervals installed at the upper portion, and the cross-linked upper structure extruded from the extruder is advanced to be installed on the sliding rod installed in the guide. As the steel pipe pillar vent is installed while advancing, the extrusion guide device is installed thereon, and the cross-linked superstructure is connected to the installation of the first cross-linked superstructure, and then extruded again into the extrusion apparatus. To complete the designed bridge width and length to complete the installation of extrusion prefabricated bridge of the designed specifications.;In order to prevent the tip portion of the cross-linked superstructure from sagging when the cross-linked superstructure is extruded and advanced between the steel pipe pillar vents, a tip support and a turning device are installed to cran in or support the tip of the cross-linked superstructure. Extrusion guide device installed on the steel pipe pillar vent when the cross-linked superstructure moves forward by installing the propulsion nose at the tip and connecting the tip and the prop nose to the reversing hydraulic jack while preventing the tip part from sagging by the wire rope connected to the device. Steel pipe column position maintaining device to be able to adjust the direction to be advanced between a pair of guides, and to maintain a constant distance from the steel pipe pile and the correct position when the steel pipe pile is type in the ground using the driving Install it, and also the steel pipe pile Laser reception target attaches a laser transmitter to the top of the cross-linked superstructure in order to ensure that the correct position and steel pipe piles are exactly vertical when typed into the furnace, and receives a laser beam emitted from the transmitter. It is to be installed in the steel pipe cap of the steel pipe column position maintaining device to maintain the exact position and vertical when the steel pipe pile in the ground.
