Abstract
The present invention can improve the drainage during flooding by reinforcing the piers of the repair structure, such as the bridge piers of the existing bridge to convert the flow of water into laminar flow to increase the flow rate of water per unit time, and also the piers of repair structures such as bridges It is to provide a reinforcement structure of a repair structure that can reduce the maintenance cost by eliminating the root crushing phenomenon. To this end, the present invention in the structure for reinforcing the pier of the quadrilateral or cylindrical structure is installed for repair structures such as bridges of the river, the width gradually narrower toward the front end of the pier on the upstream side toward the flow of water Both ends of the metal plate member is fixed by reinforcing bolts to the pier so as to have a streamlined ship shape.
Description
The present invention relates to reinforcing structures of piers used to support hydraulic structures, for example bridges constructed across rivers, or to install water gates.
In general, bridges of bridges that are installed across rivers, rivers, and the sea, or bridges of various repair structures such as inlet columns and water gates of pumping stations or drainage stations, are generally formed in the shape of wells or square columns, especially old repair structures. For example, the pillars of many hydraulic structures (so-called Saemaul bridges) in rural areas, which were constructed through the Saemaul Undong during the 1970s and 1980s, were constructed in nearly quadrangular columns to reduce budget.
Since the lower part of the pier used for the installation of the bridge and the hydrology is submerged, water is gradually eroded by water flowing over time, or the surrounding ground is scoured, causing the column to collapse. Each pillar has a problem such as causing resistance to the flow of water and causing flooding, and despite the urgent need for reconstruction, there is a problem that entails a huge budget and is neglected.
Figure 3 is a real site picture of the installation of the four-section cross-section piers in the installation of the repair structure, when the water flows at the front of the piers (pillar) when the flow of water flows divided into both sides of the column (pier) flow As you can see, you're seeing a heavy vortex (see white foam around the column). This resistance caused by the pillars has a problem such as adversely affecting the flow rate and causing the flooding in the rainy season due to the vortex formation, which reduces the water drainage capacity per unit time in the hydrologic gate.
In addition, as shown in FIG. 4, the water hitting the column (pier, 1) triggers the vortex flow (see the whirlwind-shaped arrow) toward the bottom, causing the crushing phenomenon to eat the
Accordingly, the present invention has been proposed in view of the above, and its object is to reinforce the bridge piers of bridges or repair structures installed in the past, convert water flow into laminar flow, and increase the flow rate of water per unit time in flooding. It is to provide a reinforcement structure of the repair structure to improve the drainage.
It is another object of the present invention to provide a reinforcement structure of a piers that can reduce maintenance costs by eliminating the scour phenomenon in which the piers roots of bridges or repair structures are exposed.
In order to achieve the above object, the present invention is a reinforcement structure of a pentagonal or cylindrical structure piers installed for the bridge or repair structure of the river, protruding forward toward the front portion of the piers on the upstream side toward the flow of water It has a shape of a streamlined boat having a shape but gradually narrower toward the tip, and both free ends of the metal plate member formed in the upper and lower heights to cover more than the height of the water at the bottom of the river by the fixing means to the pier wall Fixed and reinforced.
According to an embodiment of the present invention, the metal plate member having the streamlined ship shape is installed on the rear side of the piers.
In addition, according to a preferred embodiment of the present invention is characterized in that the inner space formed by the metal plate member having a streamlined ship shape is filled with sand or gravel filler.
And it is characterized by sealing the upper opening or lower opening or the upper and lower openings of the metal plate member having the streamlined ship shape with a cover plate.
In addition, according to the present invention is characterized in that the metallic collar member spread out horizontally is installed near the bottom of the river under the surface of the pier and the metal plate member.
The present invention is such that the flow of water by the reinforcement of the metal plate member made of stainless steel or the like in the four-side cross-section or circular cross-section pier installed in the repair structure in a streamlined shape, the sharp end of the metal plate member By splitting to the left and right by the two sides and flowing smoothly from the streamline surface, the flow flows backwards, which reduces the occurrence of vortices and increases the amount of water flow per unit time, reducing the risk of flooding during heavy rains (reducing the crushing phenomenon), and collar There is an effect that the member further prevents the scour phenomenon to weaken the root portion of the piers.
