Method for Reinforcing Structural Rigidity of Caisson Wall and Its Caisson

The present invention relates to a method of reinforcing a caisson wall, and more particularly, to a method for reinforcing the rigidity of a caisson wall structure in which the safety of the caisson is improved by removing and sealing air in the caisson, and to a caisson thereof.

As coastal logistics activities increase due to industrial development, the structure and characteristics of port facilities are diversifying. In particular, the need to ensure the stability of the anchored ships by maintaining the calm temperature in the port and extinguishing the waves penetrating from the open sea is emerging.

Therefore, a caisson structure for dissipating wave power is installed on the shore, quay wall, and breakwater to dissipate wave energy to protect coastal structures, and these caisson structures collide with coastal waves to dissipate wave energy has a structure.

The caisson structure for wave power distribution is configured to form a wall by forming a ground layer on the foundation ground, placing a pre-fabricated concrete caisson structure on it, and then filling the inside of the caisson with a filler or the like.

However, the caisson structure for dispersing wave power according to the prior art as described above has the following problems.

The wave power dispersing caisson structure has various types of wave power dispersing structures to dissipate waves penetrating from the open sea. This conventional wave power dispersing structure may be effective in dissipating waves, but it There is a problem in that it does not have sufficient rigidity to withstand it.

If the wave power dispersing structure does not have sufficient rigidity, the wave power dispersing structure is damaged by wave energy over a period of time. do.

In addition, various types of wave power dispersing structures may improve their wave power dispersing function due to their morphological characteristics, but they are difficult to manufacture due to their morphological characteristics and are structurally unstable, increasing the risk of damage, and repair and reinforcement are difficult due to damage. There is a problem that makes it difficult.

On the other hand, the existing wave power dispersing structure is only configured to offset waves by using the geometrical features of the structure, and a structure to improve the wave power dispersing function by using the energy of the wave itself has not been proposed.

In addition, due to the increase in design wave height due to climate change, it is necessary to reinforce the existing caisson wall. To this end, it is necessary to reduce the wave force or reinforce the rigidity of the wall. There is a problem that a huge reinforcement cost is required because the method is being adopted.
