Description

NATCH OF WATER CUTTING FOR A PIER}

The present invention relates to a water cut notch installed to prevent rainwater and the like from flowing down the bridges and bridges in the bridge in order to prevent contamination and corrosion of rust and bridges.

The bridge is composed of materials such as concrete, rebar, cement and gravel. When the rainwater or green water is encountered, the outer surface of the bridge reacts with water to corrode. In particular, when the rainwater or green water flows down the bridge and the lower part of the bridge, the bridge and the bridge, which play the most important role of supporting the bridge, are corroded.

Existing bridges do not have a device for breaking water as shown in FIG. Referring to FIG. 1, the rainwater flows along the pier slope A to the lower surface B of the bridge along with the soot of the tire passing through the bridge, the tire dust, and the like, and the chemicals contained in the rainwater corrode the pier 10.

In order to prevent corrosion of bridges and bridges of the bridges, as shown in FIG. 2, water-draining grooves 21 are formed in the bridges 20 and the bridges themselves to prevent rainwater from flowing down. Referring to FIG. 2, the rainwater flows along the bridge slope A. When the water reaches the lower edge portion 22 at which the water cutting groove 21 starts, the rainwater falls to the ground without further progressing.

Eventually rainwater cannot go to the bottom of the pier (B) to prevent corrosion.

However, most of the existing bridges are not equipped with a water cutting device as shown in FIG. 1 or rainwater is installed in order to install a water cutting groove 21 for preventing corrosion of the bridge 20 and the shift as shown in FIG. In the case of a wide groove, the support stress is weakened when a large load such as a large truck is applied at the same time, and this requires a lot of labor, time and money.

The object of the present invention is to devise to solve the above-mentioned drawbacks. The purpose of the present invention is to carry out the flow of rainwater so that rainwater, green water does not flow through the pier and the alternating flow. It is intended to provide a water cutting notch that prevents contamination and corrosion of the substructure by rainwater and green water by blocking by inducing in an outward direction.

In order to achieve the above object, the present invention, the rust and the pier in the water cutting notch is installed in order to prevent the contamination of the pier and the rust by preventing the flow of rust water by the rain on the bridge pier and alternation in advance. By inserting the insertion portion for inserting into the insertion groove, the junction portion for stably fixing to the outer surface and by providing an inlet for guiding the flow of rain water to the outside of the piers by providing a water breaking notch.

Hereinafter, the technical configuration of the present invention in detail according to the accompanying drawings.

Figure 1 is a cross-sectional view of the pier 10 is not provided with a conventional water cutting device, Figure 2 is a cross-sectional view of a bridge 20 provided with a conventional water cutting groove, Figure 3 is a state diagram of the present invention, Figure 4 Is a cross-sectional view of the present invention.

Water cutting notch 100 according to the present invention is important to configure the bridge by inducing the fall to the ground while blocking the flow of the rust water by the rain or the like on the bridge 30 and the shift in advance as shown in Figure 3 Installation is to prevent the pier (30) and the shift is contaminated or eroded by the flow of rust.

In other words, the water cutting notch 100 of the present invention is composed of the insertion portion 110, the junction portion 120 and the induction portion 130.

The insertion unit 110 is inserted into and fixed to the insertion groove 111 formed in the pier 30 and the outer inclined surface of the alternation. The insertion groove 111 is filled with silicon and the silicon is hardened so that the rainwater is inserted along the insertion groove 111 while preventing the insertion portion 110 of the notch 100 from being spaced apart from the insertion groove 111. And is installed to prevent rain water from penetrating along the insertion part 110.

And the junction portion 120 is installed by the anchor 121 in the pier 30 and the outer surface of the alternating for the stable fixing of the water cutting notch 100.

The installation of the anchor 121 is used to prevent separation of the junction portion 120 due to long-term use of the pier 30 and high load.

The induction part 130 is installed to make the rainwater fall to the ground and forms a predetermined angle with the junction part 120. In addition, the lower end portion 131 of the induction part 130 is made in a cross-sectional shape so that rain water flows through the induction part and is collected at the lowest point of the induction lower part 131. Rainwater collected at the lowest point of the guide lower end 131 receives a load of its own enough to fall into the ground and quickly falls.

As described above, according to the present invention, since rainwater and green water flowing down the pier and the shift can be naturally induced to the ground so as not to reach the lower structure, the pier and the shift, which are important substructures of the bridge, are It is possible to completely prevent contamination or corrosion, thereby improving the durability and safety of the bridge structure, and to simply install the bridge without the water cut groove at a low cost, manpower and time. Can be.
