Description

[0001] The present invention relates to a method of constructing a high-durability waterproof structure,

The present invention relates to a prefabricated block, and more particularly, to a prefabricated block for reducing flooding damage caused by flood, hurricane, and sea level rise, a prefabricated block applied to a retaining wall structure, and a method for constructing a highly durable waterproof structure using the same.

Until the twentieth century, the earth was relatively calm in terms of natural disasters. Most of the time, the earthquake, storm, and water level of the river were used to build a dam or a retaining wall.

However, in the twenty-first century, glaciers have suddenly melted down, sea levels have risen, low islands and coastal lowlands have been submerged in seawater, and conventional facilities are unable to cope with floods, hurricanes, sea level rise, And it has become an urgent situation that a new waterproof structure should be built on the shore of tens of kilometers of kilometers which had no structures in the past.

In addition, the conventional technique protects the front inclined surface with masonry, feldspar or the like at the time of embankment construction, after embankment, and this method is extremely wide and requires a lot of materials and construction costs, .

And there are reinforced concrete upright levees, but this method has difficulty in construction in soft ground.

In order to solve such a problem, a retaining wall construction system and a construction method thereof for preventing a tsunami and a flood damage are disclosed in Korean Patent Registration No. 10-1077244 (Registered on May 20, 2011) and interlocking block Korea Patent Registration No. 10-1120611 (Registered on February 20, 2012), which is hereby incorporated by reference.

However, since the S-shaped protrusion of the connecting block of the above-described conventional wall building block is easily broken during transportation and operation, and the six connecting portions formed on the six sides must be fitted together at the same time, assembly work is very difficult, In order to fundamentally prevent the rise, a waterproof structure is essential, but it has a structural problem that can not be realized.
