The present invention relates to a continuous extrusion method (incremental launching method: "ILM") that is one of the construction method of the long bridge, more specifically, due to the various site conditions of the superstructure assembled by the propulsion unit in the field When the bridge is built with the height and height difference, in the vertical and horizontal movement of the bridge upper structure manufactured at the site site up to the propulsion height, the upper structure is safe even if large-scale heavy load transportation equipment and temporary equipment are not put in operation. In the process of moving the upper structure to the propulsion position of the propulsion vent vent, while moving the upper structure to the propulsion position of the propulsion vent, the various construction equipment and structures arranged for the propulsion of the upper structure, etc. Slope lifting structure of a new type of bridge superstructure and its use It relates to a lifting slope way of the bridge superstructure.

FIG. 1 is a schematic view showing a construction of a long bridge using a general ILM, and shows the shape of the bridge immediately before the upper structure 10 of the bridge is lifted to the upper part of the propulsion tent 12. In general, as shown in FIG. 1, in the ILM, the upper structure 10 of a bridge manufactured for each propulsion unit is successively propagated in a bridge starting and ending direction of a bridge at a bridge driving height determined to be similar to the final bridge construction height. Will complete.

In order to construct a bridge using the ILM, a site site 14 for assembly and fabrication and propulsion of the upper structure 10 is formed at the rear of the propulsion position of the bridge, and the site site 14 includes site conditions and economy. If the bridge is not formed due to the height of the propulsion, the temporary construction vent 12 for the construction to achieve a height similar to the height of the top of the lower structure of the bridge to secure the propulsion height (promotion height: 推進 高).

The upper structure 10 assembled in the field site 14 prepared as described above is moved to the propulsion tent 12, and then separately pushes a separate propulsion means in the direction of the end point at the end of the bridge. To complete the bridge.

In the conventional case, when lifting the upper structure 10 assembled at the site site 14 with the propulsion temporary vent 12, various heavy materials such as a crane in order to lift the already assembled upper structure 10. Transport equipment should be put in large quantities, and the possibility of field mobilization and operation of these heavy load transportation equipment is the most important factor in determining the propulsion unit of the bridge. However, when a large amount of heavy material transport equipment is put in a large amount as described above, the construction fee is increased due to the huge fee for the operation of heavy material transport equipment, as well as the required site site according to the working radius of the transport equipment, and the ground for securing ground support capacity. Further generation of construction costs will be inevitable.

In addition, when the heavy load transport equipment is concentrated in close proximity to move the upper structure 10 vertically and horizontally, a lot of restrictions occur in the field operation of these equipment, thereby moving the upper structure 10 continuously The construction period is delayed in carrying out the continuous promotion for the bridge construction.

In addition, the size of the heavy weight transfer equipment is increased so that the propulsion unit of the bridge can be increased to increase the efficiency of the upper structure (10) hypothesis, the weight transfer equipment for interoperability due to the increase in the working radius of the equipment The possibility of collision between the two is very high, and when the equipment is damaged by the collision, since most of the expensive equipment, huge financial loss occurs.

The present invention is to solve the above problems, by moving the upper structure of the bridge from the site site to the propulsion vents inclined and horizontal, thereby minimizing the movement path and radius of the upper structure, and also the safety of the upper structure It is an object of the present invention to provide an inclined lifting structure which can be continuously and quickly and continuously moved and an inclined lifting method using the same.
