Description

Retaining wall construction structure and construction method thereof with excellent drainage, structural stability and constructability {RETAINING WALL CONSTRUCT HAVING EXCELLENT DRAINAGE, STRUCTURE STABILITY AND CONSTRUCTABILITY, AND CONSTRUCTION METHOD THEREOF}

The present invention relates to a retaining wall structure and its construction method, and more particularly, having a smooth drainage function and having structural stability that can withstand a very large earth pressure, it is easy to build construction to ensure economic efficiency by shortening the air Retaining wall construction structure having excellent drainage, structural stability and workability, and a construction method thereof.

In the 21st century, the whole world is suffering from various disasters caused by unpredictable climate change, and the damage of landslides, especially floods and local torrential rains, is increasing.

Landslides are catastrophic floods of massively disintegrated soils like waterfalls, and the extent of the damage is too large and impossible to restore. It requires thorough preparation to prevent or reduce the damage.

For example, reinforcement soil retaining wall is generally a wall structure that resists earth pressure and prevents collapse of reinforcement soil, and is used to construct apartment complexes and secure slopes, bridge bridge wing walls, and other water works.

The reinforcement soil retaining wall is designed to protect the front side of the reinforcement soil by inserting a reinforcement block having high tensile strength and good friction force horizontally into the backfill soil of the reinforcement soil to suppress the transverse displacement of the soil.

However, conventional facilities for preventing landslides should have both high durability that can withstand earth pressure as well as smooth drainage, and there is no technology or method that satisfies these conditions.

That is, since the drainage of the conventional reinforcement block induces drainage using only the nonwoven fabric, the drainage efficiency of the surface water generated in the reinforcement soil is reduced, and there is a concern that the ground of the rear wall of the retaining wall filled with soil compaction due to the continuous inflow of surface water may sink.

In addition, the surface water is discharged to the front of the reinforcement block installed in the front of the reinforcement soil has a problem that can cause a safety accident such as the reinforcement block is collapsed by the pressure of the reinforcement soil.

As a prior art, the prefabricated revetment block of Korean Publication No. 10-2012-0049106 (published: 2012.05.16.) Is fitted by inserting the frame block into the groove of the connection block in a lattice shape, and reinforcing the anchor vertically to the center of the connection block An anchor hole is formed to bury the to improve the fixing force on the slope. Such a conventional block is a revetment block for protecting an inclined surface, and the block is laid out in a plane on an inclined surface, and cannot be used where the incision and the earth pressure are large, and in particular, a separate device capable of drainage treatment. There is not.

In addition, the shaft and retaining wall block device of the Korean Utility Model Registration No. 20-0255686 (announcement date: December 13, 2001) is a technology relating to the block device for easily adjusting the angle during the construction of the retaining wall, When rainwater is introduced, there is a problem that can not be drained.
