Description

Miniaturized two-joint link type overtopping wall {Wall for preventing wave overtopping of Miniaturized two-joint link type}

The present invention relates to a new concept of technology for securing excellent constructability without space limitations by miniaturizing the overall size as well as preventing damage caused by overwater by erecting the gate when normal times are laid down and used as a passageway.

In general, in order to preemptively respond to disasters that occur in port facilities, commercial facilities, private houses, etc. due to increased inundation of land areas within port areas due to sea level rise and invasion of high waves due to climate change, land areas within existing ports As a countermeasure against disasters, damage from tsunamis is prevented by erecting or overturning protective walls.

However, this barrier is not a structure that properly distributes and reduces the pressure and impact of waves caused by typhoons or strong winds, but is manufactured by setting a certain level of pressure and impact. damage or malfunction may occur.

The barrier is erected and overturned, and if the barrier cannot withstand the impact of a tsunami while it is erect, malfunction or damage to life and property may occur. Unlike this, a method of preventing damage from a tsunami by requiring a device for distributing and reducing the tsunami by raising the protective wall buried in the ground and vertically when a tsunami occurs has problems in that civil engineering costs are excessive and maintenance is difficult.

As a prior art for resolving these problems, "Republic of Korea Patent Registration No. 1982284 Name/ Overpass and Flood Barrier for Impact Attenuation" has been disclosed.

The prior art attenuates the water pressure or impact applied to the overpass prevention wall with a shock damping device, separates the lower end of the support and the impact damping device, while the impact or water pressure transmitted from the lower end of the support in the shock damping device supported on the driving guide Provides a damping effect.

In the prior art, when the door is laid down and used as a passageway, an operating space in which a hydraulic cylinder installed horizontally can be extended must be secured, and when the door is laid down, the piston rod of the hydraulic cylinder, a pusher, a connecting rod, a shock damping device, There is a limit to reducing the overall size (front and rear length) of the overpass prevention wall, and the manufacturing cost increases due to the increase in volume, and there are many It occupies space, causing a problem of poor constructability according to space limitations.

In addition, as various foreign substances are caught in the shock damping device and driving guide exposed to the outside, the operation of erecting or laying down the gate is not smooth, and foreign substances are introduced to the lower side of the gate and piled up, leaving the gate used as a walkway for pedestrians As a result, the risk of safety accidents caused by falls is a major problem.

The present invention is a means for solving the above problems, and the gate is selectively erected while the second link rotatably connected to the lower end of the first link is unfolded or folded according to the operation of the gate cylinder coupled to the first link connected to the gate. In addition to being able to be folded or laid down, when the gate is laid down and used as a passageway, a technology is sought to realize miniaturization of the overwave prevention wall while forming a structure in which all components are accommodated in the lower storage space of the gate.

In addition, in the present invention, when the gate is erected, the safety locking device installed on the rotational part between the first link and the second link automatically sets the lock to prevent folding, and when the gate is laid down, the lock is released to smooth Strive for techniques that allow it to be folded neatly.

In addition, the present invention seeks a technique for enabling a shock absorber installed at a connection between the lower end of the second link and the buried base to act as a buffer when sea waves act on the gate.

According to the present invention, through the special technology implementation of the two-section link method, the gate can be erected to prevent overturning or laid down to be used as a passageway, and in particular, all components for operating the gate are stored in the lower storage space of the gate in a state where the gate is laid down. As it is housed in a wall, the overall size (front and rear length) of the overpass barrier can be reduced and miniaturized, which not only reduces production costs, but also improves productivity, greatly reduces construction costs by reducing the occupied area during installation, and greatly improves workability. to provide.

In addition, when the gate is laid down and used as a passageway, the upper side of the buried base is blocked by the gate and only the gate used as a passageway is exposed to the outside, thereby preventing foreign substances from entering the inner storage space of the buried base to ensure smooth operation of the gate, There is no risk of falling when pedestrians pass, providing excellent safety effects.

In addition, the present invention prevents the folding of the second link by preventing the folding of the second link while the safety locking device is automatically locked in the state in which the gate is erected, and when the gate is laid down, the second link is unlocked while laying down the gate. It folds smoothly to provide the effect of laying the gate down and using it as a passageway.

In addition, in the present invention, a shock absorber is installed at the lower end of the second link and the connection between the buried base to provide an effect of preventing damage to the overwater barrier by buffering when a strong sea wave acts on the gate.
