Description

[0001] STRUCTURE USING KEY-BLOCK AND SHEETFILE [0002]

The present invention relates to a structure using a keylock block and a sheet pile body. More specifically, the present invention relates to a structure using a keylock block and a sheet pile body, which can construct a sheet pile as a substantial wall, and can quickly and economically construct an underground wall by using a wale sheet and a sheet pile without installing a thumb pile.

FIG. 1A shows an example of a conventional excavated soil foundation girder (Patent No. 10-0726984).

That is, in the case where the ground is excavated by extending the ground in a predetermined depth and longitudinal direction such as a building, a tunnelled tunnel, a subway, a power port, a communication port, a sewer pipe and the like, and a structure is installed in the inside of the excavated ground, A vertical beam 11 (thumb pile) such as an H-file is first buried in the ground so as to be collapsed by the earth pressure (main earth pressure) at all times, and a wale 13 is installed between the vertical beams while excavating the ground, It can be seen that the digging ground supporting posts 10 are installed in such a manner that the struts 14 are installed after the soil walls 12 are sandwiched.

However, as the depth of the ground excavation deepens, the size of the earth pressure increases. Therefore, the number of the strut bosses 14 must be increased. Therefore, in order to reduce the workability and delay air, (Not shown). However, it can be seen that the earth anchor has a limitation in that it is inferior in economy.

An example of installing additional sheet files on the back side of the temporary foundation in an excavation site is shown in FIG. 1B.

In other words, as a guard which is installed on the inside surface of the excavated soil which can resist the earth pressure acting on excavation ground without the conventional brace and the intermediate file,

An excavation site girder 10 including a vertical beam or wale, which is a H file; Fixed fixed steel (20) including a sheet pile (21) embedded in the surrounding ground from the excavated soil foundation pile; And a tension member which is fixed at one end to the fixed fixing steel member and penetrates through an intermediate ground A formed between the excavating soil supporting member and the fixed fixing steel member and whose other end extends to the excavation soil foundation girder 10, And a taut system (30) comprising a tactile element (31).

As a result, since the fixed fixing steel member 20 and the tension member system 30 can sufficiently resist the required earth pressure only by the belt in the ground excavation equipment, the space inside the excavation ground can be efficiently installed It is possible to say that

However, it is advantageous in that no wale is installed. However, since it is necessary to construct both the fixed and fixed steel material 20 including the sheet 21 as well as the excavated soil foundation girder 10, economical efficiency is inevitably lowered.

Furthermore, since the fixing step is formed by using the folding space S of the sheet pile in the connection of the fixed fixing steel material including the sheet file and the excavation soil foundation girder, there is a limitation in that the workability is reduced and the process is complicated I can not help it.

FIG. 1C shows a temporary shelf 10 using another conventional sheet file 21.

That is to say, the thumb pile 11 is first spaced apart, a sheet pile 21 constituting an underground wall is constructed between the thumb piles 11 by using a guide plate (not shown) of the thumb pile, and the ground is excavated And the strut 14 is installed between the wales after the wale band 13 is installed horizontally on the exposed surface of the thumb pile.

In other words, it is known that the conventional soil web is replaced with a sheet file and the sheet file and the thumb pile are connected and fixed to each other. However, when the ground excavation depth is increased, the thickness of the sheet file 21 is inevitably increased. The plate is connected to the thumb pile, but it has to be manufactured separately.

FIG. 1 (d) shows a composite temporary shelter using a conventional sheet file.

That is, after the thumb pile 11 is installed and the sheet pile 21 is installed so as to be spaced apart from the thumb pile, a synthetic connecting member 15 is additionally provided between the sheet file and the thumb pile, And the water shield 13 is supported by the connecting member 16 and the water walls 60 and 61 (nonwoven fabric), 62 (soil plate) and 63 (cement mortar) ) In a space.

In other words, the sheet pile 21 and the water wall 60 are integrally formed. It can be seen that the cement mortar is used to construct the synthetic pile support for the purpose of order not structural stiffness.

Therefore, it is known that a sheet file, a thumb pile, a wrist band, a composite sheet file, and a connecting member are used as a temporary shelter in the past. Especially, when a sheet file is used, It can be seen that how to integrate piles and sheet files structurally is very important.

Korean Patent No. 10-0726984 (entitled " Retaining Wall System, Disclosure Date: June 14, 2007) Korean Unexamined Patent Publication No. 10-20009-0050042 (Title of the Invention: Installation Method of Soil Wall Using Linkage of Thumb Pile and Wide Shape File Installed with Guide Plates, Published Date: May 19, 2009) Korean Patent No. 10-0884289 (Title of the Invention: Composite Riverbed Facility and Construction Method thereof, Published Date: February 17, 2009)

Accordingly, the present invention is directed to a method of constructing a structure such as an underground wall and a temporary slip-hole using a sheet file. However, unlike the prior art, a thumb pile is not constructed to secure workability and economical efficiency. And to provide a structure using a keylock block and a sheet pile body capable of securing both structural rigidity and ductility.

In order to achieve the above object, a structure using a keylock block and a sheet pile body

A sheet pile body in which an inner space (S) is exposed to the opening (B) side of the structure by excavating the ground using a sheet file; And then inserted into the inner space S from the opening B side and then rotated to be fitted on both sides D of the tapered sheet pile and then pulled toward the opening B using a fixed extension And a key lock block fixedly installed on the sheet pile body, wherein the sheet pile body is formed by connecting and connecting the sheet piles so as to be arranged symmetrically with respect to each other, and an inner space S is formed by excavating the ground, And the concrete filled with the sheet file is filled in the inner space S of the sheet pile body so that the key lock block is embedded in the concrete and is fixedly installed in the inner space S.

In the construction of the sheet pile according to the present invention, the assembly is performed to secure the inner space S, and the inner space S is filled with the concrete C, which is a structural reinforcing material. It is possible to provide a composite structure by virtue of the sheet pile body and the concrete, which is possible in the order of the sheet file connection portion.

Among the structures according to the present invention, it is possible to connect the composite structure formed by the sheet pile body and the concrete to the wale band without using the thumb pile, without using a connecting member (such as H-shaped steel) After the excavation, it is inserted into the inner space S and rotated, so that the sheet pile body and the wale are structurally easily connected and fixed, and then the concrete can be integrated by using the concrete C, so that the workability and workability are not deteriorated.

Therefore, even if the depth of excavation is increased, it is not necessary to excessively increase the thickness of the sheet pile, and it is not necessary to install a plurality of struts, so that it is possible to construct the pile slabs more quickly and economically .

In addition, since the wall of the structure according to the present invention can be constructed with the composite structure of the sheet pile body and concrete, it is possible to install the wall by the sheet pile body separately from the precast casting pile.

[Sheetfilter body 100 and keylock block 200 of the present invention]

FIGS. 2A, 2B, and 2C are a perspective view and a completed perspective view of a key block and a sheet file of the present invention. FIG.

2A, the sheet pile body 100 is first formed by connecting sheet piles 110 manufactured in various cross sections to each other and pressing the pile G into the ground G by a method such as punching.

That is, the sheet pile body 100 is connected and constructed to be arranged symmetrically with respect to each other by using U-shaped sheet files, wide U-shaped sheet files, S-shaped sheet files 110, As shown in Fig.

Accordingly, the present invention is not limited to simply laying a sheet file on a ground, but is formed in a form for securing an inner space for forming an inner space S to be integrated with concrete, and is referred to as a sheet pile body 100 in particular.

Upon completion of the construction of the sheet pile body 100, it can be seen that the ground G is excavated toward the back side of the sheet pile body, and the inside space S is formed in the sheet pile body.

Next, the configuration of the key lock block 200 in the sheet pile body 100 shown in FIG. 2B is shown.

2B, it can be seen that the sheet pile body 100 is installed on the ground G and the key lock block 200 is fixedly installed in the inner space S.

The key lock block 200 uses a block body 210 and is formed so as to be fitted in the inner space S and fixed to the opening B by pulling it. Preferably, the hollow box body is formed to reduce the weight.

For example, as shown in FIG. 2B, since both side faces D of the sheet file 110 are tapered in a shape in which the inner space is narrowed toward the opening B, the block body 210 is manufactured and held toward the opening B And is fitted and fixed to both sides D of the sheet file 110 by pulling.

The key lock block 200 is for pulling the block body 210 toward the opening B and is provided with a fixed extension 220.

The fixed extension 220 may be an anchor rod, a reinforcing bar, or the like, and may be fixed with a nut or the like through the block body 210.

It can be seen that one end is fixed to the nut on the front surface of the block body 210 and the other end is formed to extend toward the opening B.

At this time, the keylock block 200 is vertically inserted into the inner space S to be inserted into the inner space S from the opening B side, and then rotated to insert the keylock block 200 on both sides D of the tapered sheet file 110 And then pulled toward the opening B by using the fixed extension 220 to finally fix and install it.

Thus, there is no need to separately secure a work space necessary for installing the key lock block 200. [

The fixed extension 220 has a function of pulling the key lock block 200 toward the opening B while setting the position of the key lock block 200 and the other end is connected to the wrist strap 310 And the precast block 320. [0053]

That is, in the case where the structure 300 using the keylock block and the sheet pile body of the present invention is a temporary sealant 300a, the wale 310 is installed, and the other end of the fixed extension 220 is fixed As shown in FIG. 2C, a separate starter 330 may be used to fix the wrist strap 310.

When the structure 300 using the keylock block and the sheet pile body of the present invention is a wall 300b as shown in FIGS. 2B and 3A, a precast block 320 is separately installed to fix the keylock block 200. The other end of the fixed extension 220 is fixed to the precast block 320,

The precast block 320 may be formed to have a through hole so as to pass through the fixed extension 220 and be fixed by a nut or the like. When the precast block 320 is formed in a rectangular plate shape, do.

At this time, as shown in FIGS. 2B and 2C, the final inner space S is filled with the concrete 120 so that the key lock block 200 and the sheet pile body 100 are structurally synthesized and integrated. The key lock block 200 is embedded in the concrete 120 and fixed in the inner space S.

The inner space S filled with the concrete 120 functions as a structure resistant to earth pressure together with the sheet pile body 100 to optimize the cross section of the sheet pile in the sheet pile body 100.

The concrete 120 may be formed stepwise over the entire penetration depth of the sheet pile 100, and a finishing die may be used if necessary.

In addition, the structure 300 integrated with the sheet pile body 100 is permanently constructed because the concrete 120 is filled and cured, and the connection portion of the sheet pile 110 is formed by the concrete 120, .

[The structure 300 using the sheet pile body 100 and the keylock block 200 of the present invention]

3A and 3B illustrate examples of the structure 300 using the sheet pile body 100 and the keylock block 200 of the present invention.

The stopper 330 may be fixed to the sheet pile body 100.

The ground on the side of the opening B for installing the wristband 310 is further excavated to further secure a working space and a wristband 310 is provided on the upper surface of the stopper 330 and a screw jack or the like is inserted between the wristband So that the strut 340 is installed.

It can be seen that the wale 310 and the strut 340 are sequentially installed on the upper surfaces of the keylock block 200 and the starter 330 while further digging the ground downward.

As a result, the final interior space S is filled with the concrete 120, and the final sheet pile body 100 and the keylock block 200 are synthesized to act as a structure. You can use it because you can install finish formwork. At this time, since the concrete 120 can be down-filled, ground work can be performed.

As a result, it can be seen that the temporary shelter 300a can be constructed as the structure 300 using the final sheet pile body 100 and the keylock block 200. [

Next, the wall 300b according to FIG. 3B is formed by filling the concrete 120 and combining the final sheet pile body 100 and the keylock block 200, thereby constructing the structure as a vertical wall. It can be said to be a kind of retaining wall installation method.

First, the wall 300b according to FIG.

The sheetfilter body 100 is constructed by connecting and forming the inner space S by using the sheetfilm 110,

The ground G is excavated such that the upper portion of the sheet pile body 100 is exposed.

The key lock block 200 is vertically inserted into the opening B and then rotated so as to be fitted to both sides D of the tapered sheet pile 110. Then, (B).

At this time, it can be seen that a separate starter 330 can be used for the setting. The stopper 330 may be formed of a steel or the like extending into the precast block 320 and may be connected to the stopper 330 by a coupler or the like.

The precast block 320 may be installed on the exposed surface of the wall 300b, so that it is exposed after the installation. For example, in the form of a rectangular plate.

As a result, the final interior space S is filled with the concrete 120 so that the final sheet pile body 100 and the keylock block 200 are combined to act as a structural body. You can use it because you can install finish formwork. At this time, since the concrete 120 can be down-filled, ground work is possible.

At this time, the reinforcing bars 121 may be further disposed in the inner space S to place the concrete 120.

At this time, it can be seen that a bottom plate 350 for constructing a pedestrian bridge or a bicycle road is further installed on the wall 300b.

Also, as shown in a cross-sectional view taken along the line A-A in Fig. 3B,

The grouting material 130 and the concrete 120 may be additionally formed in the outer space S2 between the inner spaces S.

That is, after the outer space S2 is excavated using an auger or the like to insert a finishing plate, a reinforcing net, and the like, the concrete 120 is conveyed to the outer side Can be formed in the space S2,
