Description

Filler for retaining walls

The present invention relates to a filler for a retaining wall, and more particularly, to a filler for a retaining wall that can support a pile against a strip, corresponding to various distances between the strip and a pile.

The construction method of the CIP (Cast In Place) mud wall among the construction methods of the mud wall to prevent the collapse of the back surface of the excavation in the underground excavation work is applicable to almost all the grounds regardless of the ground conditions. Is applied to many sites in the downtown area because it can be constructed close to the boundary of the site because it can construct a wall with the outer retaining wall of the underground structure.

In the construction method of the CIP mud wall, prior to commencement of the excavation work, a perforation hole is formed on the boundary of the excavation ground using a device such as an earth auger to form a perforation hole, and then a reinforced concrete structure is formed in the perforation hole to construct the underground. It is formed by forming a CIP pile and continuously constructing the pile in a columnar manner to form a retaining wall.

At this time, in the case of a high-depth excavation work or a ground with a high groundwater level, the back pressure on the mud wall acts much more than in the general case, so the H-shaped steel is buried inside the CIP concrete at regular intervals to increase the rigidity of the mud wall.

On the other hand, the reverse perforation method of the underground structure is constructed by constructing an earthen wall on the outer periphery of the underground structure to be constructed, drilling the location of the main pillar of the underground structure, constructing a column foundation and a steel column, and then excavating the ground for each basement layer, Installation, deck plate installation, slab reinforcement and slab concrete are repeated to proceed from the upper layer to the lower layer.

In the course of the reverse construction process, the back pressure of the earthen wall is supported by steel beams and reinforced concrete slabs that are horizontal members.

And when the foundation of the structure is completed after the bottom layer excavation is completed, the CIP mud wall and the slab together with the reinforced concrete part of the pillar are struck, in other words, by pouring the outer wall of the reinforced concrete from the lower layer to the upper layer to join the CIP mud wall. The steps will proceed.

Therefore, a support member for transmitting earth pressure between the CIP mud wall and the steel beam or the reinforced concrete slab is required until the outer wall of the reinforced concrete is joined by the shun, which is transverse to the steel beam 20 as shown in FIG. 1. A spacer 51 is installed between the strip 50 installed and the thumb file 11, which is a CIP file in which H-beams are buried, and in situ file 10 and strip 50 (CIP files in which H-beams are not embedded) ), sandwiching material 52, such as a section of a steel sheet.

However, as described above, the in-situ pile 10 is formed by punching the ground and pouring concrete in place, as described above, and the verticality of the in-situ pile 10 is not accurate and the outer surface is also uneven. The gap between the pile 10 and the belt length 50 is not entirely uniform.

As such, the spacing between each of the in-situ files 10 with respect to the strip length 50 is different, and the fitting material 52 inserted therein must also be cut individually to fit each spacing, and thus the fitted material 52 Even in the installation, the installation work of the fitting material 52 is accompanied by a lot of hassle and air delay because the fitting material 52 needs to be welded and fixed to the band 50 in a state held by hand or a mechanism so as not to fall down. It acts as a factor of this, and the hassle of this work can also lead to secondary construction.

Alternatively, a flange surface 123 having an outwardly protruding shape may be formed on both sides of the belt-shaped support portion 110 so that the belt-shaped support portion 110 is placed on the ends of the pair of flanges 53.

Hereinafter, a filler for a retaining wall according to an embodiment of the present invention will be described with reference to FIGS. 3 to 6.

3 is an exploded perspective view and a combined perspective view of a filler for a retaining wall according to an embodiment of the present invention, FIG. 4 is a cross-sectional view showing a state in which the filler for a retaining wall of FIG. 3 is applied, and FIG. 5 is according to an embodiment of the present invention An exploded perspective view and a combined perspective view showing another example of a filler for a retaining wall, and FIG. 6 is a cross-sectional view showing a state in which the filler for a retaining wall of FIG. 5 is applied.

3 to 6, the filler 100 for a retaining wall according to an embodiment of the present invention includes a belt support 110, a pile support 130, and a distance adjusting unit 150.

The strip support 110 is installed in the strip 50, which is H-shaped or I-shaped steel, and is fixed to the space or flange 53 between the pair of flanges 53 and the web 55 of the strip 50, and the fastening member 153 has a fastening hole penetrating in the vertical direction.

The pile supporter 130 contacts the

piles

10 and 11 to support the

piles

10 and 11.

The distance adjusting part 150 has a plate shape, and the pile support part 130 is coupled to one end. Then, a distance adjusting hole 151 having a length in a direction perpendicular to the longitudinal direction of the belt-like support 110 is formed so that the fastening member 153 is fastened to penetrate the distance adjusting hole 151 and the fastening hole at the same time. Accordingly, when the fastening member 153 is loosened, the distance adjusting unit 150 is movable, and when the fastening member 153 is tightened, the movement of the distance adjusting unit 150 is limited. As a result, the distance from the belt support 110 to the pile support 130 is adjusted according to the distance between the belt 50 and the

piles

10 and 11.

More specifically, as shown in FIGS. 3 and 4, in the present embodiment, the belt support 110 is located in a space formed between the pair of flanges 53 and the web 55, and the pair of flanges Among the 53, the vertical surface 111 may be disposed adjacent to the flange 53 located on the pile (10, 11) side. The height of the vertical surface 111 is formed to be equal to or higher than the height from the web 55 to the end of the flange 53, and the support surface 113 can be extended from the top of the vertical surface 111. Here, the support surface 113 is formed to be inclined downward, and the end of the support surface 113 may extend to an edge formed by the web 55 and the opposite flange 53.

The width from the vertical surface 111 to the end of the support surface 113, that is, the width of the belt support 110 is equal to the length of the web 55 so that the belt support 110 is positioned between the pair of flanges 53 Or narrower than this. By the way, if the width of the band support 110 is narrower than the length of the web 55, the band support 110 is not fixed to the band 50, so a means for fixing the band support 110 to the band 50 is required Do.

To this end, a fixing hole in which a screw-type fixing member 117 is screwed may be formed on the vertical surface 111. The fixing hole may be formed directly on the vertical surface 111, or may be formed by an insert nut (not shown). The fixing hole may be formed in a direction perpendicular to the flange 53. Accordingly, when the fixing member 117 is positioned and rotated in the fixing hole, the fixing member 117 may protrude into a space between the vertical surface 111 and the flange 53. Thus, as the fixing member 117 fills the space between the vertical surface 111 and the flange 53 to make the fixing member 117 protrude more, the strap supporting portion 110 can be firmly fixed to the strip 50. .

On the other hand, in this embodiment, the support surface 113 may be further provided with a jungle prevention surface 115 disposed horizontally with the web 55 on top. The anti-slip surface 115 is in contact with the bottom surface of the distance control unit 150 to prevent the distance control unit 150 from being pushed as a friction force, and the bottom of the distance control unit 150 and the anti-skid surface 115 have a sawtooth shape. Even if a large force is applied to the distance adjusting unit 150 by forming irregularities corresponding to each other, the movement of the distance adjusting unit 150 can be prevented. However, the above-described is only one example, and may be configured in any way as long as it can prevent friction of the distance adjusting unit 150 by generating frictional forces with each other. For example, a rough surface may be formed on the bottom surface of the anti-slip surface 115 and the distance adjusting unit 150 to be configured to generate friction with each other.

Alternatively, as shown in FIGS. 5 and 6, in this embodiment, the belt-shaped support portion 110 may be formed such that the support surface 113 becomes the slip prevention surface 115 soon. In this case, the vertical surface 111 is disposed adjacent to any one of the flanges 53, and the support surface 113 may be a right-angled surface having an angle of 90 degrees rather than an inclined surface. That is, the support surface 113 having an angle of 90 degrees from the top of the vertical surface 111 is extended so that the band-shaped support part 110 may have a'c' shape. Accordingly, a surface that is perpendicular to the vertical surface 111 may be the sliding prevention surface 115. Likewise, elements that generate frictional forces, such as toothed or rough surfaces, can be applied.

In this embodiment, a fastening hole may be formed in the jungle prevention surface 115. The fastening hole may also be formed directly on the anti-slip surface 115 like the fixed hole, or may be formed by an insert nut (not shown).

Therefore, as described above, the fastening member 153 is fastened to penetrate the distance adjusting hole 151 and the fastening hole at the same time. Accordingly, when the fastening member 153 is loosened, the distance adjusting unit 150 is movable, and when the fastening member 153 is tightened, the movement of the distance adjusting unit 150 is limited. That is, after loosening the fastening member 153 and moving the distance adjusting unit 150 so that the pile support 130 installed in the distance adjusting unit 150 contacts the

piles

10 and 11, locking the fastening member 153 Corresponding to the distance between the strip (50) and the pile (10, 11) can support the pile (10, 11).

The pile supporter 130 has a surface that supports the

piles

10 and 11 in contact with the

piles

10 and 11, and the pile supporter 130 may be rotatably installed in the distance adjusting unit 150. The axis of rotation 131 between the pile support 130 and the distance adjusting unit 150 is parallel to the longitudinal direction of the

piles

10 and 11. That is, it is perpendicular to the longitudinal direction of the belt length 50, and the pile support 130 can rotate in the horizontal direction. As a result, the

files

10 and 11 can be supported by rotating the file support 130 according to the installation angle of the

files

10 and 11, so that the

files

10 and 11 correspond to the

files

10 and 11 installed at various angles. ).

There are two types of piles (10, 11) used in the CIP method: the thumb pile (11), which is a CIP pile with H-beams embedded, and the pile file (10), which is a CIP pile with H-beams, not embedded, As for the thumb pile 11, the surface of the part supported by the filler 100 is partially removed so that the surface of the pile pile 130 comes into contact with the pile support portion 130, and the place of the pile pile 10 has a surface of the pile pile 130 touching the curved surface. .

Therefore, in order to support both the thumb pile 11 and the in-situ pile 10 in correspondence, the pile supporting portion 130 may be formed in a flat surface or a curved surface in contact with the

piles

10 and 11. That is, when the pile is a thumb pile 11, the pile support 130 may be formed as a flat surface, and when the pile is a pile pile 10, the pile support 130 may be formed as a curved surface.

In addition, when the surface where the pile support 130 and the file 11 are in contact is flat, that is, when the pile is the thumb pile 11, the pile 11 and the welding are provided between the pile support 130 and the file 11 by welding. A fixed welding part 133 may be further provided. The welding part 133 may be coupled to the pile support part 130.

When the file is in place 10, the file support 130 is formed in a curved surface so that it can cope with the file 10 installed at any angle, so that the file support 130 and the distance adjustment unit 150 are rotatably combined. Since there is no need, they can be fixed to each other.

The pillar 100 of this embodiment formed as described above may be installed on both the upper and lower sides of the web 55.
