Description

CARBON ANCHOR STRUCTURE OF PIER'S BASIS FOR BRIDGE}

The present invention relates to a carbon rod anchor structure for pier foundation jungle prevention, and more particularly, it is connected to the pier foundation to prevent the phenomena due to the large amount of water in the event of natural disasters such as a great flood, and also protect the bridge, The present invention relates to a carbon anchor anchor structure for preventing piling foundations to ensure safety.

In general, in Korea, floods occur every year, and many road facilities are destroyed.

Many protectors are constructed to prevent the destruction of these road facilities, but the reality is that they are forced to leave it unavoidably every year.

1 is a view for explaining the problems of the conventional bridge, the concrete foundation plate 20 is seated on the soil layer 10 in the water, the bridge 30 and coping (top) of the concrete foundation plate 20 While 40 is spoken, the elastic support 50 is seated on the coping 40 so that the prestressed concrete beam 60 is stacked.

In the prestressed concrete beam 60, a concrete upper plate 70 is poured into the upper construction.

In the bridge 90 having the above-described structure, after the concrete base plate 20 is seated on the top of the soil layer 10, the bridge 30 and the coping 40 are constructed. As such, when the water level surface rises due to flooding, there is a problem that the bridge 90 is caused to fall each year due to rainwater flowing along the flow direction such as an arrow.

That is, there is no special support structure for the concrete base plate 20 constituting the lower structure of the bridge 90, an accident that the entire bridge 90 will collapse.

The present invention, in order to solve the above problems, the present invention is connected to the concrete foundation plate constituting the pier foundation to protect the bridge, as well as to secure the safety of the road pier foundation carbon preventive anchor bar structure To provide for that purpose.

1 is a view for explaining the problems of the conventional bridge.

Figure 2 is a view showing a state in which a carbon rod anchor for preventing piling foundation push of the present invention is installed.

Figure 3 is a detailed view of the carbon steel anchor anchor for preventing piling foundation of the present invention.

The present invention, in order to achieve the above object, the present invention, the pier foundation consisting of the floor concrete and concrete foundation plate, the pier and coping formed in the center upper portion of the pier foundation, elastic support, prestressed concrete beam and bridge deck In the bridge comprising, a carbon rod anchor penetrating the bottom concrete and the concrete base plate is installed and the cover concrete is placed on top of the carbon rod anchor to prevent the bridge falling, while the carbon rod anchor is a carbon rod, permanent The anchor head, the pressure plate and the anchor head are integrally fastened, the carbon rod is formed in a rod shape, and the permanent anchor head and the pressure plate are formed with a grouting hole and a plurality of permanent anchor holes penetrated at the center thereof. When the permanent anchor head and the pressure plate penetrates through the carbon rod, an anchor head is installed on the upper part. It is fixed, and the grouting is injected into the grouting hole to provide a carbon anchor anchor structure for preventing piling base, characterized in that the carbon rod anchor is configured as a support structure.

Hereinafter, with reference to the accompanying drawings will be described the configuration of the present invention.

2 is a view showing a state in which the carbon rod anchor for preventing piling foundations of the present invention is installed, when the bridge 900 is constructed in the river or the sea, the underwater soft rock layer 100 is formed by pouring the bottom concrete 200 , The concrete base plate 300 is formed on the bottom of the concrete 200, the carbon rod anchor 400 is fixed to the cover concrete 500 on the top of the concrete base plate 300 soft rock layer 100 Is installed to penetrate through, the pier 600 is installed on the center of the concrete base plate 300.

The bridge 900, the bottom concrete 200 constituting the bridge foundation 200 and the carbon rod anchor 400 penetrating through the concrete base plate 300 is installed, preventing the phenomenon that the bridge foundation is transmitted by the flood flow rate. It becomes possible.

Figure 3 is a detailed view of the piercing base rolling prevention carbon rod anchor of the present invention, Figure 4 is a view for explaining a state in which the piercing base rolling prevention carbon rod anchor of the present invention is manufactured.

The carbon rod anchor 400 has a structure in which the carbon rod 410, the permanent anchor head 420, the pressure plate 430 and the anchor head 440 are integrally fastened, and the upper portion of the concrete base plate 300 is dug inward. It is installed in the groove.

The carbon rod 410 is drawn out of the carbon fiber spool 412 by the resin tank 414 filled with the resin and heated by the heater 416 on the outside, and is provided on the side of the heater 416. ) Is cut at the cutter 418 to produce a carbon rod.

Although the carbon rod 410 has been described only in the form of a circular rod, it will be obvious that the shape may be manufactured in a circular, rectangular, and polygonal form.

The permanent anchor head 420 and the pressure plate 430, the grouting holes 424, 434 are formed in the center of the body so that the carbon rod 410 can pass through, grouting is poured, grouting holes A plurality of permanent anchor holes 426 and 436 are formed in contact with 424 and 434 to allow the carbon rod 410 to penetrate.

When the carbon rod 410 penetrates the permanent anchor head 420 and the pressure plate 430, it is fixed to the upper portion of the permanent anchor head 440 by the anchor head 440, and then grouting is injected into the grouting holes 424 and 434. Will be closed.

The pressure plate 430 is formed in a circular shape, and the anchor head 440 is formed in a nut structure.

As can be seen in the above configuration, the bridge 900, the carbon rod anchor 400 is installed so as to pass through the bottom concrete 200 and the concrete base plate 300 constituting the pier foundation, the carbon rod anchor 400 Since the cover concrete 500 is poured on the upper part of the pipe, even when the water level rises due to flooding and the water pressure rises excessively, the destruction of the bridge foundation is prevented, so that the fall of the bridge 900 is prevented. Prevent accidents beforehand.

The effect by the structure of this invention mentioned above is demonstrated.

In the carbon rod anchor of the present invention, the carbon rod anchor is installed to penetrate the bottom concrete and the concrete base plate constituting the bridge foundation of the bridge, and the cover concrete is placed on top of the carbon rod anchor. Even when the water pressure rises excessively, since the destruction of the foundation of the bridge is prevented, the fall of the bridge is prevented, so that a safety accident can be prevented in advance.
