Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to one skilled in the art. And the present invention is only defined by the scope of the claims.

In the present invention, since the steel sheet pile is composed of a plurality of sheet piles as shown in Fig. 1, the steel sheet pile and the sheet pile may be understood as synonymous.

As shown in FIG. 1, two or more sheet piles (a) of a steel sheet pile are connected without being separated from each other to form a steel sheet pile, and the steel sheet pile is struck against the ground for earthworks.

The sheet file a is formed in a substantially U shape and bent at both ends of the sheet file a. The sheet file a and the sheet file a are connected to each other at their bent portions to form a connection portion b.

When such a steel sheet pile is buried in the soil and is recovered to the ground, it is difficult to separate the sheet file (a) from the sheet pile (a) because a natural bonding force by the soil, And when the sheet is pulled and separated by an excessive force, the cross-sectional damage of the connecting portion (b) and the sheet pile (a) is greatly generated, thereby reducing the recyclability of the member. That is, there is a problem that the recovery rate of the product is lowered. In addition, when the two sheet piles (a) are reused together, there is a high possibility that the cross section is damaged again in transportation, hunting and construction, and it is not easy to transport and store or is not economical because it occupies a large space. Therefore, it is necessary to effectively separate the sheet file (a) and the sheet file (a) without damaging the end face.

As shown in Fig. 1 (b), since the bent portions of the two sheet files a are slidingly coupled to each other at the connecting portion b, they are pulled out to each other to separate the sheet file a can do.

The two sheet files a have an inverted cross section, that is, if one sheet file a is opened upward, the other sheet file a is opened downward, The sheet file (a) shows the shape of a wave.

The steel sheet pile drawing system 100 according to the present invention will be described below.

Referring to FIG. 3, in the steel sheet pile pulling system 100 according to the present invention, one sheet file (a) connected to each other through a connecting portion (b) is fixed while the other sheet file (a). In the present specification, a fixed sheet file (a) is referred to as a fixed sheet file, and a sheet file (a) to be extracted is referred to as a drawing sheet file.

5B, the upper sheet p is opened downward and the lower sheet p is opened upward, and the two sheet piles a , The lower sheet file (a) was used as the fixed sheet file (a), and the upper sheet file (a) was used as the drawing sheet file (a). This is because the lower sheet file comes into contact with the flange of the lower support 10 to be described later, so that it can be easily fixed to the fixed sheet pile a. For the same reason, the upper sheet pile can not come into direct contact with the flange of the upper pile 11 So that the sheet can be relatively easily moved to form the drawing sheet file (a).

5B, the lower sheet pile a is supported by one lower pile 10 and the flange of the lower pile 10 is in contact with the sheet pile a. The upper sheet pile (a) is supported by a lower pedestal (10) and an upper pedestal (11). A part of the height of the upper support 11 is inserted into the opening of the upper sheet pile a to support the upper sheet pile a.

In FIG. 5B, the H-shaped section is exemplarily shown as the upper pedestal and the lower pedestal, but a square pipe may be used, and it is not limited to an H-shaped pipe or a square pipe.

A separate reinforcement plate may be installed on the web of the lower pedestal 10 or the upper pedestal 11 to reinforce it. In addition, the lower pedestal 10 may be welded or bolted to the bottom fixed steel plate 14.

The upper and lower pedestals 11 and 10 supporting the upper sheet pile can be welded or bolted together and fixed therebetween.

Referring to FIG. 2, a steel sheet pile pulling system 100 according to the present invention includes a lower pedestal 10 on a bottom fixed steel plate 14 and an upper pedestal 11 on a lower pedestal 10. As described above, the two sheet files a to be separated are placed on the upper pedestal 11 and the lower pedestal 10, respectively, and the upper sheet file a and the lower sheet file a are put down.

A plurality of fixing lids 20 as shown in Fig. 5A are provided in the longitudinal direction of the sheet pile a to cover the upper sheet pile a and the lower sheet pile from top to bottom. In this way, the movement of the lower sheet file (a), that is, the fixed sheet file (a) is suppressed in the process of pulling out the sheet file (a), specifically the upper sheet file So that the pulling force from the hydraulic pushing device 70 applied to the sheet file (a) can be maximized.

A plurality of fixing sheets 20 are provided in the longitudinal direction of the sheet pile (a), which is an elongated member, thereby reducing the slenderness ratio of the sheet pile a to thereby prevent buckling. In addition, It can be prevented from being caught.

The stationary lid 20 is configured to cover the sheet pa in a direction perpendicular to the longitudinal direction of the sheet pa and is provided between the support pawls 24 provided at both ends in a direction perpendicular to the longitudinal direction, A hinge 25 is formed at one end of the support shaft 20 and the fixing cover 20 is fixed to the support pawl 24 by bolts 22 or the like at the other end. 5B, the stationary lid 20 is inserted into the opening of the lower sheet pile a and presses the lower sheet pile a against the lower pedestal 10 and the hinge 25 And a holding lid 23 for allowing the fixed lid 20 to be pivoted easily around the center of the fixed lid 20. [ The fixed lid 20 is rotated downward about the hinge 25 so as to abut the upper sheet file a so that the upper sheet file a can not be detached from the fixed lid 20 and the lower sheet file a Is formed in such a shape that the pressure applying member 21 can be pressed and fixed.

In addition, the lower sheet pile (a) fixed by the fixed lid 20 is restrained from being displaced in the longitudinal direction of the sheet pile a by the movable stopper 30. As shown in FIG. 6, the movable stopper 30 serves to keep the lower sheet file a from sliding in the longitudinal direction of the sheet file a when the upper sheet file a is pulled out, The blocking wall 35 is prevented from moving (pushed) in a state in which the cantilever 34 covering a part of the file a covers the sheet file a at the C site. The movable stopper 30 itself is fixed to the flange of the lower pedestal 10 or another reinforcing plate 33 by means of the rib 36 and the bottom plate 37 and the flange of the lower pedestal 10, A fixing hole 32 is formed in the reinforcing plate 33 and the bottom plate 37 so that the movable stopper 30 can be fixed to the lower pedestal 10 or a separate reinforcement So that it can be fixed to the plate 33. The additional reinforcing plate 33 is determined depending on the thickness of the flange of the lower pedestal 10. When a separate reinforcing plate 33 is used, the fixing hole 32 is formed by the flange of the lower pedestal 10, (33).

The lower pedestal 10 itself is fixed to the ground via the bottom fixed steel plate 14.

3, a plurality of the fixing holes 32 are formed at predetermined intervals in the longitudinal direction of the sheet pile a. Therefore, the movable stopper 30 can be fixed at a required position in accordance with the lengths of the upper sheet file (a) and the lower sheet file (a). If the required pulling length is not obtained during the separation process, the sheet file (a) is moved back to the hydraulic pushing device 70 to be described later and the pulling process is repeated. In this case, the movable stopper 30 Can be fixed. Therefore, in this specification, the stopper is referred to as a movable type.

Up to now, a method of fixing the sheet pile (a) with the upper pedestal 11, the lower pedestal 10, the fixed lid 20 and the movable stopper 30 in the steel sheet pile pulling system 100 has been described. Hereinafter, a method of extracting a fixed sheet file (a) will be described.

In the steel sheet pile drawing system 100 according to the present invention, the upper sheet pile, that is, the drawing sheet pile a is partially pushed out by using the hydraulic pushing device 70, The drawing sheet file a is pulled out to complete the separation of the upper sheet file (a) and the lower sheet file (b).

2 to 4, the hydraulic pushing device 70 may include a hydraulic jack 71, a reaction force wall 72, and an auxiliary support 73. 3, a push plate 40 is attached to the hydraulic jack to push out the upper sheet file a. Since the sheet file (a) is a thin plate material, the plate 40 is attached to the hydraulic jack 71 without being directly pushed by the hydraulic jack 71, And the width and width of the cross section are determined so that the load of the hydraulic jack 71 can be evenly distributed to the sheet file.

The upper sheet pile a and the lower sheet pile a can be relatively easily separated after they are once separated from each other at the connecting portion b while sliding the two sheet piles a relative to each other. Thus, after the upper sheet file (a) is separated from the lower sheet file (a) by a predetermined length, the upper sheet file (a) is pulled through the winch-type pulling device 60.

The winch type pulling device 60 includes a winding device 61 which is connected to the wire W and pulls the wire W. The winch type pulling device 60 is configured such that after the hook 50 is connected to one end of the wire, the hook 50 is hooked on the upper sheet file a so that the hook load of the winding device 61 is transferred to the upper sheet pile a ).

In the steel sheet pile pulling system 100 of the present invention, since the hydraulic pushing device 70 or the winch type pulling device 60 is used in combination with the push of the hydraulic pushing device 70 and the pull of the winch type pulling device, The volume and the capacity of the pushing device or the pulling device can be reduced, the load can be prevented from being increased by either device, and the pulling speed can be increased. This is advantageous in terms of the working space and efficient operation of each device, and the load of each device is reduced, thereby reducing the risk of accidents such as cable breakage during the process.

Hereinafter, a steel sheet pile pulling method using the steel sheet pile pulling system 100 of the present invention will be described:

1) Two sheets of untreated steel sheet piles (a) are moved by a crane and placed on the drawing system 100, that is, on the lower pedestal 10 and the upper pedestal 11 (S210).

2) The fixed steel sheet pile a is fixed by the movable stopper 30 to the fixing hole 32 previously drilled in the lower pedestal 10 or the reinforcing plate 33 at step S220.

3) Steel Sheet Pile (a) The fixing cover 20 is placed on the steel sheet pile (a) and fastened to the support pawl 24 with the bolts 22 (S230).

4) The hydraulic pushing device 70 is attached to the leading end of the drawn steel sheet pile (a) to push the pushing load while adjusting the pushing load (S240).

5) Steel Sheet Pile (a) When the connection portion (b) between the two steel sheet piles is loosened by drawing a predetermined length, for example, 20 to 30 cm, the wire is attached to the drawn steel sheet pile (a) (A) of the steel sheet paired with each other by pulling the steel sheet paddle 60 by one (S250).

6) or the winch type pulling device (60), move the steel sheet pile (a) to the hydraulic pushing device (70) again with the crane and repeat the above step 1).

7) Steel sheet pile (a) The fixed lid 20 is removed and the drawn product is moved to the product loading position by the crane (S260).

Although the embodiments of the present invention have been described in detail with reference to the accompanying drawings, those skilled in the art will appreciate that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
