Description

Panel type natural stone retaining wall and panel natural stone retaining wall construction method {PANNAL TYPE NATURE STONE RETAINING WALL AND CONSTRUCTION METHOD THEREOF}

The present invention relates to a panel-type natural stone retaining wall, and more specifically, to securely connect and fix the panel-type natural stone using a reinforcement material, and to adjust the length of the reinforcement material according to the construction site according to the distance between the panel-type natural stone and the cut slope. The present invention relates to a panel-type natural stone retaining wall capable of improving workability and a method of constructing the panel-type natural stone retaining wall.

Generally, cut slopes exist mostly in rivers, lakes, or hills that are flattened (eg, apartment complexes) or roads.

Since these cut slopes are mainly formed by artificial cutting work, if the left exposed sides are cut as they are, the risk of slope collapse is expected due to the continuous weathering process such as air contact and rainwater penetration. In other words, when the cohesive force of the slope is weak and a large amount of rainwater is penetrated, the slope is easily broken, causing a situation.

In order to prevent the occurrence of such a situation on the cut slope, a wall that resists the earth pressure of the slope, that is, a retaining wall is constructed on the perimeter of the slope to prevent the loss of soil and, of course, to cause the situation. Block in advance.

As a slope reinforcement method for cut slopes, a site-pouring concrete retaining wall method has been used in the past, in which case installation and dismantling of the formwork requires excessive work force and construction costs, and at the same time, the economic feasibility of construction was deteriorated. Since the formwork had to be retained until the concrete retaining wall placed in the formwork was completely cured and cured, a problem such as a long construction period was involved.

Application No. 10-2010-0076533 discloses a retaining wall structure for reinforcing cut slopes and a method of construction thereof, to which a nailing and anchoring means are simultaneously applied.
