Description

Apparatus for adjusting the position of superstructures broken away in a bridge and constructin gmethod for position adjustment using the apparatus}

The present invention is to allow the bridge to play a normal role by moving the bridge upper structure to the normal position of the bridge or bridge when the bridge upper structure is moved to one side from the bridge or bridge due to flooding, ground subsidence, etc. The present invention relates to a position adjusting device for a detached bridge superstructure and a position adjusting construction method using the same.

Position adjustment device of the present invention is composed of a horizontal movement bracket and a vertical movement bracket installed on the alternating or piers,

A vertical movement bracket consisting of a support jaw installed on the surface where the pier or the alternating device is installed on the upper part of the support on which the anchor bolt holes are formed, and a reaction force in which the vertical movement hydraulic jack is installed on the lower part of the support;

A vertical wall across the width of the central support plate is installed at right angles to the central support plate on both sides of the central support plate where a plurality of anchor bolt holes are formed, and the space formed by the reaction force plate extending from the central support plate and the vertical wall is formed by four wing walls. It is a position adjustment device consisting of a horizontal moving bracket formed in the space to install a horizontal moving hydraulic jack in the space and to fix a plurality of steel rods on the outside of the reaction plate.

By using the position adjusting device, a positioning device is installed to restore the bridge upper structure moved to the existing position by the amount of deviation such as d1, d2 ... shown in FIG. Moving and restoring to its original position is to install a plurality of vertical movement brackets as shown in Figure 3 on both sides of the bridge or the long side 14 as shown in Figure 1 anchor fixing to the side of the bridge or alternator with anchor bolts And the horizontal movement bracket shown in Figure 2 by installing a plurality of both side short sides (15) of the piers or alternator of Figure 1 fixed with an anchor bolt on the side of the central support plate 27 and alternating or piers, and the steel bar of FIG. 22) are connected to each other with a steel rod as shown in Figures 4, 6, 9, and then connected and fixed using a fixing fixture and alternately as shown in Figures 5 and 8 Lifting a certain amount of the upper structure of the bridge on one side by using the vertically moving hydraulic jack installed on the upper reaction force 53 of the vertical movement bracket 50 installed on the long side 14 of the bridge, the upper portion of the bridge on the side of the bridge near the shift While raising the structure, while raising the crossover, while completing the raising of the upper structure of the bridge on the bridge pier in the middle of the bridge so that the eccentric load does not occur in the upper structure of the bridge is raised to a certain amount of the top as shown in Figure 1 Alternatively, the horizontal movement bracket of FIG. 2 acts on the horizontal movement hydraulic jack installed as shown in FIGS. 4, 6, and 9 on the alternate short side 15 so that the piston of the hydraulic jack pier using the reaction plate 26. Alternatively, when the side of one end of the bridge upper structure installed on the shift to move horizontally already lifted by a certain amount of upward by the vertical hydraulic jack A horizontally moving force acts on the raised bridge superstructure so that the bridge superstructure is moved horizontally by a planned amount so that the bridge superstructure is moved to the originally installed position. The movement order of the hydraulic jack installed in the bracket is to move as described in Figure 3 is to install the bridge upper structure to fix the bridge in place by repositioning the bridge upper structure of a certain amount deviated from the bridge or alternating.

An object of the present invention is to install the position adjustment device of the present invention in the bridge or bridge when the bridge upper structure is separated from the bridge or bridge to one side due to flooding, subsidence of the ground, etc. can not serve as a normal bridge As shown in Fig. 1, the bridge upper structure is vertically raised in a certain order, and then the bridge upper structure is moved to the normal position of the bridge or the bridge by horizontally shifting the amount of deviation of the bridge upper structure from each shift or bridge. It is to ensure the safety of the to act as a normal bridge.

Generally, when a bridge is flooded, bridge or foundation ground is unequally settled, and the bridge superstructure of the bridge or bridge is separated by a certain amount to prevent the bridge from acting as a bridge, the bridge is installed after the installation of the vent around the bridge or bridge. Repairs were made after the superstructure was raised and moved horizontally. However, this repair method does not have a practically applicable repair method when the piers or shifts are riverbed or soft ground. In this case, after dismantling the bridge that lacks safety, the bridge is installed again. Therefore, when this method is used, the bridge is dismantled and then installed again, resulting in excessive construction costs due to the overlapping of the demolition cost and the installation cost. There was a problem that the waste and construction period is longer.

The present invention has been proposed in view of the above matters, and after the separated bridge upper structure is installed after the horizontal moving bracket and the vertical moving bracket, which are position adjusting devices, are installed on the piers or shifts to lift the separated bridge superstructure, It moves horizontally by the amount so that the bridge superstructure can be installed in the normal position of the bridge or the pier to perform the normal role of the bridge, the construction method using such a device is dependent on the surrounding conditions where the bridge or pier is located It is possible to reduce the construction period and construction cost by simply moving the upper structure of the bridge to the normal position by simply installing the position adjusting device on the bridge or shift, and there have been many difficulties in the disposal of the waste materials due to the dismantling of the bridge. The present invention does not generate such waste materials, It is to provide a construction method that can contribute to protection.
