Description

Single Cell Caisson for Concrete Block Replacement and Port Construction Method Using Same

The present invention relates to a method of constructing a harbor structure using a caisson and a caisson thereof, and more particularly, to a single-cell caisson for replacing a concrete block that enhances the fixing force by increasing the frictional force of the caisson, and a method of constructing a harbor structure using the same.

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 vessel by maintaining the calm temperature in the port and extinguishing the waves penetrating from the open sea is emerging.

Accordingly, a caisson structure for dissipating wave energy is installed on the shore, quay wall, and breakwater to dissipate wave energy to protect the coastal structures. 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.

In addition, when constructing port structures such as water sheds and breakwaters using concrete blocks, a large number of blocks of a certain size are used to build them in a zigzag manner, so they can be installed with a small crane, but they have to be stacked one by one, so the construction time is long. It is impossible to build all blocks uniformly, so it is difficult to build a high-quality structure. In addition, since it is designed to ensure that 100% of its own weight is made of concrete to ensure the stability of the structure, there is a possibility that the manufacturing cost will increase.
