The present invention relates to a retaining wall, and more particularly, to a retaining wall assembling apparatus using a permanent anchor and a concrete panel configured to sufficiently withstand the earth pressure applied to the concrete panel by the fixing force of the permanent anchor fixed to the ground and the connection force of the concrete panel. It is about.

Generally, a wall that resists earth pressure so that soil does not collapse is called a 'retaining wall'. Among these retaining walls, there are retaining walls using permanent anchors, and retaining walls using rock bolts or small nails (hereinafter referred to as 'lock bolts').

The retaining wall is composed of a staircase and an upright (lamination type). A permanent anchor is used to fix a concrete panel having an appropriate thickness and a rectangular parallelepiped along the slope of the slope to cover the slope of the slope. This will prevent the situation.

In this way, the retaining wall construction method using permanent anchor and concrete usually casts shotcrete on the inclined slope slope as much as the amount of data, and after the appropriate time has elapsed, drilled a hole, and then shotcrete secondly. ), The concrete panels are installed before the shotcrete is cured, and then they are installed and tensioned as permanent anchors.

However, the upright type of the retaining wall using the permanent anchor has the disadvantage that the vegetation space such as the tree planting is not provided on the retaining wall by covering the entire slope of the slope with the concrete panel. As the contact surface of the upper and lower parts is reduced, the bearing pressure (bearing force against earth pressure) is lowered, which causes a problem of using a large number of permanent anchors.

On the other hand, the retaining wall formed in the stepped form is in close contact with the left and right sides of the concrete panel in a linear contact, and the upper and lower parts are assembled with a separate base concrete panel, the assemblability is lowered, the earth pressure is lowered, so that a large number of permanent anchors There is a problem that needs to be used.

The present invention has been made in order to solve such a conventional problem, the problem to be solved of the present invention is to engage the inclined mutually inclined to the left and right sides, the contact area is widened, the upper and lower parts are supported with the foundation concrete panel It is to provide a stepped retaining wall assembly device is increased.

Another problem is to provide an upright retaining wall assembly apparatus in which left and right coupling portions and upper and lower portions are inclined to be inclined with each other so that the contact area is widened to increase the bearing pressure.

The problem solving means of the present invention is a retaining wall assembled and retained by the fixing force of the permanent anchor on the stepped slope slope and the coupling force of the plurality of concrete panels and the base concrete panel, the concrete panels, the first and second panels made of a rectangular parallelepiped; First and second central coupling pieces protruding outwardly to correspond to central regions of left and right ends of the first and second panels; First and second upper coupling pieces which protrude outwardly from the inner upper portions of the first and second central coupling pieces to the upper ends of the first and second panels, respectively; A left and right coupling member comprising first and second lower coupling pieces protruding outwardly from the inner lower portion of the first and second central coupling pieces to a lower end of the first and second panels, respectively; And a reinforcement protrusion member provided on the front surface of the first and second panels, the foundation concrete panel is coupled, and the permanent anchor is inserted and fixed to reinforce the strength of the first and second panels.

In addition, the present invention in the retaining wall is assembled and held up and down and left and right by the fixing force of the permanent anchor to the slope of the slope and the coupling force of the plurality of concrete panels, the concrete panel, the first, 2, 3, 4 panels made of a rectangular parallelepiped; First, second, third, and fourth central coupling pieces protruding outwardly to correspond to central regions of left and right ends of the first, second, third and fourth panels; First and second upper coupling pieces which protrude outwardly from the inner upper portions of the first and second central coupling pieces to the upper ends of the first and second panels, respectively; First and second lower coupling pieces protruding outward from the inner lower portion of the first and second central coupling pieces to a lower end of the first and second panels, respectively; Third and fourth upper coupling pieces which are spaced apart from the upper portion of the third and fourth central coupling pieces by a predetermined distance and protrude outwardly to upper ends of the third and fourth panels, respectively; Left and right coupling members comprising third and fourth lower coupling pieces protruding outward from the inner lower portion of the third and fourth central coupling pieces to a lower end of the third and fourth panels, respectively; First, second, third, and fourth panels having upper and lower tightly inclined surfaces formed to correspond to upper and lower portions of the first, third, and second and fourth panels, respectively, and the upper and lower parts of the first, third, second, and fourth panels are in close contact with each other. Inclined pieces; And a reinforcement protrusion member provided on the front surface of the first, second, third and fourth panels, respectively, to which the permanent anchor is inserted and fixed, and to reinforce the strength of the first, second, third and fourth panels.

The present invention provides the effect that the left and right coupling portions of the concrete panel fixed to the slope of the stepped slope is mutually inclined to be inclined with each other to widen the contact area, and the upper and lower portions are supported by the base concrete panel to increase the bearing pressure.

In addition, the joints of the left and right sides of the concrete panel, which are fixed to the slope of the upright type as a permanent anchor, are inclined to interlock with each other at an inclined angle, thereby increasing the contact area, thereby increasing the pressure of the concrete panel and the shotcrete.
