More particularly, the present invention relates to a cladding cladding structure and a construction method thereof, The present invention relates to an assembled dam structure and a method of constructing the dam structure.

Generally, the dam construction is installed to prevent intrusion of foreign water by surrounding the work area when installing work structures such as dams, seawalls, hydrants and bridges in rivers and oceans.

Typical methods for installing this water film include a sheet pile method, a caisson method, and a method of embedding and building sand and earth.

Here, the sheet file method is a method in which a plate file is continuously installed on the surface of the seabed so as to prevent intrusion of foreign water, which is suitable for a small scale water tank such as a river tributary, and is difficult to apply to a large- have.

In addition, the caisson method is a method of making the foundation by making the caisson which is the base of the structure and grounding the caisson while excavating the soil of the seabed ground. It is accompanied with great difficulty in carrying and installing due to the high weight of the caisson, And it is difficult to apply to the ground where the deep and soft layer is distributed thickly.

In addition, the method of constructing the tailings by filling the slag and the soil requires a long period of construction, and there is a problem that the cost of the construction is increased due to the large amount of materials, manpower and equipment to be input.
