The present invention relates to a small river arch bridge and its construction method, and in particular, it is possible to assemble the construction without an intermediate bridge to shorten the construction period of the bridge and to save the construction cost, it is possible to minimize the damage or pollution of the river It's about what you have.

In general, a bridge or a bridge is usefully used as a means for allowing a person or a vehicle to pass by connecting water on both sides of the bridge and roads on both sides of the bridge.

In order to construct such a bridge (bridge) that is usefully used, it is necessary to install a plurality of bridges along the length and to install beams on the bridges.

In addition, in order to install a bridge, the river must be damaged and the environment must be managed.

However, small rivers with relatively narrow widths are enormous in cost, but because of the long time required for construction, concrete bridges or synthetic resin pipes were installed and concrete was placed on them to construct small bridges.

This bridge, also known as a diving bridge, is usually used to allow water to flow inside the pipe and to allow people or vehicles to pass through the bridge above it.

The above-mentioned submersible bridges were constructed in mountainous areas with narrow river width or less use. However, in rainy seasons such as rainy seasons, the amount of flowing water is so high that it is impossible to pass through the upper part of the bridge. Because of the problem that leads to secondary damage.

Therefore, such a submerged bridge is temporarily useful, but there is a limit to use it semi-permanently over a long period of time, so that many bridges (20m or less) are built and concrete bridges are constructed.In order to construct a large number of bridges, , Plywood, lumber, pipe, support, etc.) to make the mold by woodworking, and then reinforce the concrete and then cast concrete.

Therefore, because the temporary remodeling process is required and the concrete curing process is required, it takes a long period of construction and a huge cost of construction and a problem of damage to the river due to the construction of the bridge.

The present invention is to be able to shorten the construction period by allowing the bridge to be constructed without an intermediate bridge in order to solve the conventional problems as described above.

In addition, the present invention is to be able to construct a pier without installing a temporary material or a mold to save the construction cost and shorten the construction machine.

In addition, the present invention is to provide an arch bridge for the small river that can prevent the damage of the river to be able to assemble the bridges and the top plate cured in the place other than the construction.

In addition, the present invention by assembling the top plate on the support beam to construct a bridge in the arch form to distribute the power of the pier on both sides to provide an effective and ideal bridge at a low cost many bridges in remote areas or mountainous areas It is intended to contribute to the user's convenience by constructing.

The present invention in the construction of bridges in small rivers: pier at both edges of the river and pier assembles a plurality of bridges in the form of blocks cured elsewhere in place, and support beams assembled in front and rear of the both piers And, it is to provide a small river arch bridge, characterized in that the bridge formed by placing a plurality of top plates assembled on the front and rear prevention paper beam, concrete on the top plate.

The present invention in the construction of bridges in small rivers: the foundation installation process of digging at both edges of the river and placing concrete in place, and the pier to assemble the pier by assembling the pier in the form of blocks elsewhere on the foundation An assembly process, a support beam assembly process of assembling support beams in front and rear of both piers, a top plate assembly process of assembling a plurality of top plates on the front and rear prevention paper beams, and a concrete pouring process of constructing bridges by filling concrete on the top plate. It is to provide a small river arch bridge construction method characterized in that made.

Hereinafter will be described in detail according to the accompanying drawings an embodiment of the construction can be assembled in a short period of time while minimizing damage to the small river according to the present invention, the construction of the arch bridge at a low cost.

1 is a perspective view showing the pier and the support beam of the present invention, the excavation on both sides for erecting the bridge, the concrete base on which the concrete is laid so as to fix the lower part of the pier installed on the bottom surface of the river on one side ( 10), the lower piers (11) (12) on the concrete foundation (10) and the screw assembly and then the upper piers (13) (14) on the lower piers (11) (12), The upper and lower piers (11) (12) (13) and (14) is screwed on one side of the pier is built up.

The other side also forms a concrete foundation 20 on which concrete is poured so as to fix the lower part of the pier installed on the bottom surface of the river as described above, and establishes the lower piers 21 and 22 on the concrete foundation 20. When the upper piers 23, 24 are erected on the lower piers 11 and 12, and the upper piers 21, 22, 23, 24 are screwed together, the other piers are erected.

In the above example, the lower piers and the upper piers were shown as an example of the construction, but if you want to increase the height of the pier between the upper and lower piers need to be shaped like the lower piers according to the height of the height can be adjusted.

In addition, the upper piers 13, 14, 23, 24 should form inclined surfaces 13a, 14a, 23a, 24a on one side, and the inclined surfaces 31, 32, 41 of the support beams 30, 40. And 42) to support the force.
