Description

Reinforced Plate and Reinforcement Method of Protective Wall for Vehicle Road Using DSB Method}

The present invention relates to a reinforcement and reinforcement method of the road barriers using the DSB method to more firmly reinforce the existing barriers installed on the side of the vehicle driving road to minimize the second large damage caused by the vehicle accident.

In general, on a road constructed for high speed driving of a vehicle such as a highway, a coastal road, a mountain road, or a national highway, or a road adjacent to a dangerous area such as an ocean, a river, or a cliff, the driving vehicle inadvertently leaves the lane. Or, if the vehicle is pushed out after the first collision with another driving vehicle and is directed to the side area of the road, it is likely to have a second large accident.

In order to minimize the probability of such an accident, conventionally, a fixed height barrier using reinforced concrete is fixedly installed along the side of the road, so that even if the driving vehicle is shocked due to an accident or the like, the vehicle is moved off the road. It prevents large-scale human accidents caused by road departures.

The barrier on the side of the road is completed by temporarily installing a barrier-shaped formwork at the construction site of the road, placing a plurality of reinforcing bars in the inside, and then placing and curing concrete mortar in the formwork. .

On the other hand, the reinforced concrete barriers installed on the road are exposed to the outdoors, so that stresses due to weathering by wind and moisture filling due to rain are continuously applied. It is very likely to cause chemical damage due to smoke, dust, etc. from the vehicle due to the continuous running of the vehicle, so that the existing barriers are dismantled and replaced with new ones at regular intervals, or the aged barriers are replaced. There is a need to repair or reinforce.

However, the conventional barrier replacement method requires the complete dismantling of the existing barrier, and then the formwork must be re-installed to reinforce the reinforcement and the concrete mortar, thus not only prolonging the construction period but also adding construction personnel and equipment. In addition, there is a serious problem that the cost burden is increased due to the additional cost of construction materials, and control of the road due to construction is inevitable, which may act as a major factor in traffic congestion.

In addition, even in the case of repairing or reinforcing a conventional aging barrier, as a partial replacement of the barrier, only partially repairs the damaged portion of the existing barrier itself, or mobilizes the formwork to reinforce the concrete mortar casting. Since the reinforcement work is performed, the possibility of solid and reliable repair or reinforcement work will be reduced, and the progress cycle of repair or reinforcement work on the firewall will be shortened, thereby increasing the cost burden. And there is a problem that the stability of the firewall is also reduced.
