Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a load supporting permanent earth retaining wall,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load supporting permanent earth retaining wall and a method of constructing the same. More specifically, the present invention relates to a load supporting permanent retention wall and a method of constructing the same, Since it is installed in the inside of the wale, the thickness is reduced, and the thickness of the concrete covering the front of the earth retaining plate is small. Thus, the construction cost can be reduced and the weight can be reduced. Supporting permanent earth retaining wall and a method of constructing the same.

In addition, by inserting the horizontal and vertical load supporting members having a lattice structure for enhancing the load distribution supporting force between the upper and lower horizontal wales, the thickness of the covering of the concrete is reduced and the construction cost is reduced, And a tensile load is maintained so as to prevent the reinforcement material such as an anchor from bending and bending. The present invention also relates to a method of constructing the earth retaining wall.

In order to secure the structural stability, the retaining wall used in civil engineering, construction, etc., is designed to have a vertical H-shaped steel pile and a horizontal H-shaped steel wale, which are installed at a spacing of 1.2 m to 2.0 m, It is a structure that is constructed by arranging a plurality of reinforcing bars in the rear inner side of the H-shaped steel band. Therefore, there is a structural engineering problem that requires an installation work space for reinforcing steel reinforcement, thereby increasing the thickness of the retaining wall and requiring a large building area.

In order to solve the above-mentioned problem, the present applicant has proposed a technique (Patent Registration No. 1029040, Registration Date 2011.06.04) (hereinafter referred to as "permanent earth retaining wall structure having a gap retaining pile for prevention of corrosion " Patent registration technique of the present applicant ").

The retaining wall structure, which is the registered technology of the applicant of the present invention, maintains the vertical H-shaped steel material gap inserted vertically into the soil slurry, and maintains the vertical H-shaped steel gap so that the corrosion resistance of the thumb pile is greatly improved. By covering the corrosion-preventing gap-maintaining layer 103 of the predetermined thicknesses D1 and D2 of the portion completely buried in the ground excluding the exposed surface 102 with concrete or the like, even if exposed to the soil moisture for a long period of time, H-shaped steel body is not corroded and can withstand loads such as earth pressure.

Therefore, it is necessary to eliminate the installation space for reinforcing steel reinforcement behind the horizontal H-shaped steel band, and to minimize the thickness of the rear portion of the horizontal H-shaped steel band of the earth retaining wall structure, And the construction cost can be reduced by reducing the cost.

1, the pedestal 400, which is a steel, is horizontally raised on a bracket 360 fixedly connected to a lower portion of a vertical H-shaped steel material spacing holding body 101 of the earth retaining wall structure And is welded and fixed to the front outside of the horizontal H-shaped steel band 300 which is fixedly connected to the front exposed surface 102 of the vertical H-shaped steel material gap maintaining thumb pillar body 101. [

The pedestal 400 is welded and fixed to one side of the front surface of two horizontal H-shaped steel wales 300 spaced apart at regular intervals, and is connected to an earth anchor, a nail or a strut beam through a reinforcing material insertion hole (not shown) The reinforcing member 460 of the reinforcing member 460 has a function of guiding the reinforcing member 460 to be inserted into the hole inclined at a predetermined angle (for example, 20 to 30 degrees) into the grounding gravel 900 and supporting the reinforcing member 460 such as an earth anchor.

At this time, the stiffener 460 such as the earth anchor is disposed between the body 101 of the vertical H-shaped steel spacing-maintaining thumb pile with the earth retaining plate 200 made of a plurality of wood plates fixed therebetween and between the horizontal H- (Not shown), and is fixed and fixed in the ground sheet gravel 900 by inserting it into a hole drilled slantingly at a predetermined angle (for example, 20 to 30 degrees) in the ground sheet gravels 900.

The pedestal 400 is welded and fixed to the front surface of the vertical H-shaped steel spacing-maintaining thumb pillar body 101, the horizontal H-shaped steel band 300 and the horizontal H-shaped steel band 300 exposed forward of the earth retaining plate 200. The concrete 960 is inserted through a reinforcing material inserting hole (not shown) of the pedestal 400 and inserted and fixed in the ground sheet gravel 900 to prevent corrosion of the reinforcing material 460 such as an earth anchor, Thereby preventing the soil moisture from flowing out through the soil retaining plate 200.

As described above, the pedestal 400 of the patent registration technology of the present applicant has the exposed end of the stiffener 460, such as an earth anchor, inclined at a predetermined reference angle (for example, 20 to 30 degrees) (Not shown) on the front exposed surface of the stiffener 460, the exposed end of the stiffener 460, such as an earth anchor, must be passed through an ordinary anchor head (not shown, Head).

Therefore, the pedestal 400 should be protruded on the front side of the two horizontal H-shaped steel wales 300 so as to have a certain length in the forward direction with respect to the vertical surface welded at both ends, The exposed end of the stiffener 460, such as an earth anchor, inclined at a predetermined angle relative to the ground, is inserted into the reinforcing material insertion hole (not shown) at a right angle (90 degrees).

That is, since the pedestal 400 is structurally large in thickness (for example, a thickness of 30 cm or more is required), the covering thickness (for example, a thickness of 70 cm or more) of the concrete 960 cured in front of the earth retaining soil plate 200 There is a problem that the construction cost of the cursor is large and there is a problem that the efficiency of construction is lowered because the construction work can not be performed due to the heavy and heavy manpower.

The pedestal 400 welded and fixed to the front surface of the horizontal H-shaped beam band 300 has a large thickness and is heavy. The base 400 is wrapped around the horizontal H-shaped beam band 300 to prevent corrosion, And one of the upper and lower wales 300 functioning as a transverse H-shaped girder function is fixed to each of the braces 360 by the thickness of the concrete covering layer of the curing 960, The reinforcing material 460 such as an earth anchor is bent at the construction site of the actual earth retaining wall to reduce the tensile load.

In other words, conventionally, since the wale band 300 is supported only by the brace 360, there is a problem that the support force of the stiffener 460 is reduced without being horizontally held by the load of the concrete covering.

Although the applicant's patent registration technique is not clearly shown in the drawings, it is also possible to use a hole that is slanted obliquely at a predetermined angle (for example, 20 to 30 degrees) in the ground sheet gravel 900 and a hole on the front exposed surface of the pedestal 400 The reinforcing material 46 such as an earth anchor or the like is formed at a right angle (90 degrees) to the front exposed surface of the pedestal 400 formed with the reinforcing material insertion hole (not shown) Is inserted in a straight line in the stiffener insertion hole (not shown).

However, in the process of welding the upper and lower ends of the heavy and heavy pedestal 400 to the one side of the front surface of the two horizontal H-shaped steel wales 300 at the construction site, a predetermined angle (for example, 20 to 30 degrees It is difficult to precisely perform the welding work so that the holes drilled slantingly on the front exposed surface of the pedestal 400 and the stiffener insertion holes (not shown) are positioned exactly on the straight line. Therefore, there is a problem that the reinforcement material 460 such as earth anchor is bent at the construction site of the actual earth retaining wall to reduce the tensile load.
