[0033] Referring to FIGS. 1 to 9, a pile driver having a tower-type floating soil removal device according to one embodiment of the present invention comprises: a column member (10) installed on a vehicle moving to a construction site and arranged vertically on the ground; an auger screw (12) that performs drilling work on the ground while moving up and down along a guide rail (11) provided on the column member (10); a driving unit (13) that provides forward or reverse rotational power to the auger screw (12) while moving along the guide rail (11); a floating soil removal device (230) installed on another guide rail (11) among a plurality of guide rails (11) provided on the column member (10); a cover member (50) installed on the floating soil removal device (230); a variable support unit (70) that movably connects the floating soil removal device (230) to the column member (10) installed upright on the ground; and a member installed on the column member (10). It includes an auxiliary rail (90), a striking member (94) that strikes a pile being constructed on the ground while rising or falling along the auxiliary rail (90), a position moving part (100) that supports the auxiliary rail (90) so as to be movable, and a mounting fixing part (110) that restrains or releases the striking member (94) from the auxiliary rail (90).

[0034] Therefore, when carrying out ground reinforcement work to construct piles on soft ground, the auger screw (12) is positioned facing the ground by driving the vehicle, and the auger screw (12) is lowered and rotated by the operation of the drive unit (13) to construct a drilled hole in the ground.

[0035] As described above, a steel reinforcement structure is inserted into the drilled hole, and cement mortar is injected into the steel reinforcement structure and hardened to proceed with the pile construction.

[0036] When the hardening of the pile is complete, the process proceeds by striking the upper part of the pile with a striking member (94) so ​​that the pile is firmly inserted into the ground, thereby allowing the ground reinforcement to be carried out more effectively.

[0037] The auger screw (12) that has completed the drilling operation is discharged to the ground by the reverse power of the drive unit (13). At this time, the floating soil interposed between the spirals of the auger screw (12) is discharged to the outside of the spirals of the auger screw (12) by a floating soil removal device (230) installed on one side of the column member (10).

[0038] The floating soil removal device (230) of the present embodiment includes a main body case (232) installed on a column member (10) so as to face an auger screw (12) that is raised and lowered along the column member (10) by the operation of a driving unit and drills a hole in the ground, a plurality of wire members (280) installed to protrude from the main body case (232) and inserted into the gap between the spirals of the auger screw (12) to discharge floating soil, a fixed part (250) that supports the wire members (280) and is movably installed on the main body case (232), a movable support part (270) that provides an elastic force to press the fixed part (250) in one direction so that the wire members (280) slide while maintaining a state of close contact with the inner wall of the spiral of the auger screw (12), and a variable support part (70) that movably connects the main body case (232) to the column member (10).

[0039] In this embodiment, as described above, a plurality of wire members (280) are installed along a main body case (232) that is formed vertically, so the plurality of wire members (280) are simultaneously inserted into the gap between the spirals of an auger screw (12) that is positioned adjacent to the main body case (232) and moves, thereby allowing the wire members (280) to remain inserted into the gap between the spirals of the auger screw (12) throughout the entire time the auger screw (12) passes through the section facing the main body case (232), thereby enabling the continuous discharge of floating soil.

[0040] A partition panel (234) is installed in the main body case (232) to divide the internal space into multiple spaces, and a rotatable connecting piece (236) is installed on the outer wall of the main body case (232) to be rotatably connected to a variable support member (70). Thus, one side of the main body case (232) is rotatably connected to the variable support member (70) by the rotatable connecting piece (236), and the interior of the main body case (232) is divided into left and right directions by the partition panel (234) which is installed vertically in the center of the main body case (232).

[0041] The fixing part (250) includes a first fixing block (252) that supports a wire member (280) and is installed at a distance in one space of the main body case (232) partitioned by the partition panel (234), a second fixing block (254) that supports a wire member (280) and is installed at a distance in another space of the main body case (232) partitioned by the partition panel (234), and a fixing pin (256) that is installed in the main body case (232) and rotatably supports the first fixing block (252) or the second fixing block (254).

[0042] In addition, the first fixed block (252) and the second fixed block (254) are arranged alternately with each other and are arranged in the spiral shape of the auger screw (12).

[0043] Accordingly, the interior of the main body case (232) is divided into two spaces that are vertically elongated and arranged adjacent to each other by partition panels (234), and a plurality of first fixing blocks (252) and second fixing blocks (254) are installed in each space at a constant interval, and the first fixing blocks (252) and second fixing blocks (254) are arranged in a spiral shape forming a zigzag shape.

[0044] The fluid support member (270) of the present embodiment includes an elastic member (272) having one end connected to a first fixed block (252) or a second fixed block (254), and a connecting hole (274) formed at the other end of the elastic member (272) to be connected to a fixed pin (256).

[0045] The inner ends of the first fixed block (252) and the second fixed block (254) are each rotatably supported by a fixing pin (256), and the upper end of the elastic member (272) is connected to the outer ends of the first fixed block (252) and the second fixed block (254), and the lower end of the elastic member (272) is fixed by a connecting hole (274) with an adjacent fixing pin (256).

[0046] Accordingly, the outer ends of the first fixed block (252) and the second fixed block (254) are provided with an elastic force that pulls them downward, so when the outer wire member (280) passes through the gap between the spirals of the auger screw (12), the wire member (280) is pulled downward by the elastic member (272) and slides in close contact with the spiral of the auger screw (12).

[0047] As described above, since the wire member (280) slides while maintaining a state of close contact with the spiral of the auger screw (12), the floating soil attached to the spiral of the auger screw (12) can be separated from the spiral of the auger screw (12) and discharged as it interferes with or collides with the wire member (280).

[0048] The variable support member (70) of the present embodiment includes a connecting body (72) having a connecting hook (74) that is fixed by being hooked to a column member (10), a connecting block (76) that is rotatably connected to the connecting body (72) and rotatably connected to a main body case (232), a first connecting cylinder (77) installed between the connecting body (72) and the connecting block (76), and a second connecting cylinder (78) installed between the connecting block (76) and the main body case (232).

[0049] Accordingly, when a rod is extended from the first connecting cylinder (77) by the operator, the gap and angle between the connecting body (72) and the connecting block (76) are adjusted, and when a rod is extended from the second connecting cylinder (78), the gap and angle between the connecting block (76) and the main body case (232) are adjusted, thereby allowing the distance at which the wire member (280) is inserted into the spiral inner wall of the auger screw (12) to be adjusted while adjusting the gap between the column member (10) and the main body case (232).

[0050] The position moving part (100) of the present embodiment includes a fixed block (101) equipped with a hook member (102) to slide along the guide rail (11) of the column member (10) and change the position and fix it, an extension member (103) extending laterally from the fixed block (101) and having a rotating piece (104) installed at its end, an angle adjusting part (106) extending from the rotating piece (104) and connected to an auxiliary rail (90) to adjust the gap between the extension member (103) and the auxiliary rail (90), and a connecting member (105) branching out from the extension member (103) to support the auxiliary rail (90).

[0051] Therefore, when the impact process of inserting a pile into the drilled hole is carried out after the drilling operation by the auger screw (12) is finished, the impact member (94) can be moved to an accurate position facing the top of the pile member by the operation and manipulation of the position moving part (100).

[0052] The angle adjustment unit (106) includes a bolt member (107) extending from one end of the rotating piece (104), a nut pipe (108) installed on the extension member (103) to fasten the bolt member (107), and an adjustment cylinder (109) installed between the other end of the rotating piece (104) and the auxiliary rail (90).

[0053] The bolt member (107) is coupled to the threads formed on the inner wall of the nut pipe (108) so as to be fastened, and the angle of the rotating member (104) can be adjusted while adjusting the gap between the rotating member (104) and the extension member (103) by rotating the nut pipe (108) in the forward or reverse direction.

[0054] Additionally, when a rod is extended from the adjustment cylinder (109) provided at the other end of the rotating piece (104), the gap between the rotating piece (104) and the auxiliary rail (90) is adjusted, and the gap and angle between the auxiliary rail (90) and the column member (10) are adjusted, and the position of the striking member (94) and the heavy object (96) installed on the auxiliary rail (90) can be adjusted.

[0055] Therefore, when a striking process is required after the drilling work and pile construction are completed, the auxiliary rail (90) and the striking member (94) are moved by operating the nut pipe (108) and driving the control cylinder (109) to be positioned opposite the pile, and the striking process can be carried out by dropping the striking member (94) and the heavy object (96).

[0056] The mounting fixing part (110) of the present embodiment includes a coupling block (112) provided on an auxiliary rail (90), a mounting base (114) rotatably extending from the coupling block (112), a mounting hook (116) formed at the end of the mounting base (114), and a locking projection (118) protruding from a striking member (94) and engaging with the mounting hook (116).

[0057] Therefore, after the striking process is finished, the striking member (94) and the heavy object (96) are raised along the auxiliary rail (90), and then the hooking projection (118) protruding from the striking member (94) or the heavy object (96) is hooked onto the mounting hook (116), so that the heavy object (96) and the striking member (94) can be maintained in a raised state along the auxiliary rail (90).

[0058] Thus, a tower-type floating soil removal device and a pile driver equipped with the same can be provided, which are installed to rotate in the opposite direction to the auger screw that is drilling on the ground and rising to the ground, thereby removing floating soil remaining on the auger screw, and a plurality of wire members are arranged vertically in a long manner, and the wire members passing through the gap between the auger screw spirals are pressed against the auger screw spirals, thereby effectively discharging floating soil remaining on the spirals.

[0059] Although the present invention has been described with reference to an embodiment illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0060] In addition, although a tower-type floating soil removal device and a pile driver equipped with the same have been described as examples, this is merely illustrative, and the removal device and the pile driver equipped with the same of the present invention may be used in products other than the tower-type floating soil removal device and the pile driver equipped with the same.
