Background Technology

[0002] Generally, there are various methods for ground improvement or the installation of cutoff walls. Among them, methods that increase ground strength by injecting and hardening grouting materials such as chemical solutions or cement milk into the ground, or methods that form a solidified body by mixing with soil through high-pressure spraying, are widely known.

[0003] As equipment used for such ground improvement, a drilling auger has a rod installed vertically in front of a crane or excavator, a wire drawn from the crane's winding drum passes through the top of the rod, and an auger is installed at the end of the wire to rotate a screw.

[0004] Such a drilling auger is guided along the guide rail of the rod and moves up and down, pressing the screw by its own weight. In this way, the conventional drilling auger presses the screw by the weight of the rod and rotates the screw to drill the riverbed or the ground.

[0005] However, conventional augers use a mounting frame to guide the auger along a guide rail; since auger mounting frames vary depending on the type and method of construction, there is a disadvantage in that separate augers and mounting frames must be prepared. Prior art literature

[0019] The auger box module (2) of the present invention is configured such that an auger drive body (11) having a hydraulic motor (12), a gearbox (13), and an auger drive gear shaft (14) is embedded in a rectangular tubular hexahedral box (10). Additionally, an enlarged opening (20) is formed in one or more of the front and rear sides of the hexahedral box (10) of the auger box module (2), preferably in both the front and rear sides, to facilitate the entry of tools or bolts for bolt fastening operations. Furthermore, a fastening hole matrix (24) is formed in the left and right side walls and the upper cover wall (18) of the hexahedral box (10), in which bolt fastening holes (22) are arranged in a matrix to facilitate inter-module coupling or expansion.

[0020] In addition, bolt fastening holes (22) for constructing a double row of augers can be further arranged on the front and rear walls of the auger box module (2).

[0021] The upper cover wall (18) of the auger box module (2) is preferably configured separately as shown in FIG. 2, and the auger drive body (11), which includes a hydraulic motor (12), a gearbox (13), and an auger drive gear shaft (14), is mounted inside the cuboid box (10) of the auger box module (2) by bolt fastening using left and right 'U'-shaped brackets (16).

[0022] In addition, among the constituent modules of the present invention, the link connecting member module (4) is a means module that is detachably linked to the tip of the arm (52) of heavy equipment for auger standing and moving, such as an excavator (50 in FIG. 12) for connecting an auger.

[0023] As shown in FIGS. 1 to 3, the link connecting member module (4) of the present invention is configured such that bolt fastening holes (23) are arranged to be aligned with any bolt fastening holes (22) within the fastening hole matrix (24) of the upper cover wall (18) of the auger box module (2) or some of the bolt fastening holes (22) within the fastening hole matrix (24) formed on the upper surface of the spacer box module (30).

[0024] Therefore, the bolt fastening hole (23) of the link connecting member module (4) is configured to be bolted by aligning it with the bolt fastening holes (22) in the fastening hole matrix (24) of the upper cover wall (18) of the auger box module (2), or bolted by aligning it with the bolt fastening holes (22) in the upper surface fastening hole matrix (24) of the spacer box module (30).

[0025] In the present invention, an auger box module (2) including the link connecting member module (4) shown in FIGS. 1 to 3 can be used alone or in multiple numbers for soft ground construction.

[0026] FIGS. 4 to 7 show schematic examples of diversifying auger arrangements using a detachable modular auger device including a link connecting member module (4) and an auger box module (2) in the present invention.

[0027] The detachable modular auger device of the present invention enables single-axis auger construction by using a single auger box module (2) alone as shown in FIG. 4 on soft ground, or enables multi-axis auger construction by configuring the left and right side walls of two or more auger box modules (2) to be aligned with each other and bolted together as shown in FIG. 5 and FIG. 6.

[0034] The spacer box module (30) is provided in a size that allows the auger's axis spacing to be spaced apart as required by the worker. As shown in FIG. 9, an enlarged opening (20) for entry for bolt fastening is formed in one or more of the front and rear sides of the cuboid box, and bolt fastening holes (22) are formed in a row arrangement on the left and right side walls and the top wall of the cuboid box.

[0035] In addition, as shown in FIG. 9, a fastening hole matrix (24) is formed on the upper wall of the spacer box module (30) in which bolt fastening holes (22) that can be aligned with the bolt fastening holes of the link connecting member module (4) and fastened with a bolt (26) are arranged in a matrix.

[0036] Therefore, the auger box module (2) is side-fixed to the left and right walls of the spacer box module (30) by bolt fastening, and the link connecting member module (4) is fastened to the upper part of the spacer box module (30), so that it can be linked to an excavator (50 in FIG. 8) and used for construction.

[0037] The spacer box module (30) can be manufactured in various spacing sizes, and by appropriately using the spacer box module (30) manufactured to the spacing size according to the worker's requirements, the axis spacing of the augers in the two auger box modules (2) combined as shown in FIG. 8 can be adjusted.

[0038] FIG. 10 is an example diagram showing that the axis spacing of four augers can be adjusted using the detachable modular auger device of the present invention, and FIG. 11 is a perspective view of the axis spacing adjustment spacer module used in FIG. 10.

[0039] As shown in FIG. 11, a fastening hole matrix (24) is formed on the upper surface of the cross-shaped spacer box module (40) in which bolt fastening holes (22) that can be fastened with the link fastening member module (4) and the bolt (26) are arranged in a matrix, and a fastening hole matrix (24) in which bolt fastening holes (22) that can be fastened with the bolt (26) are arranged in a matrix is ​​also formed on the inner wall surface of all four sides.

[0040] Four auger box modules (2) arranged in quadrants are spaced apart using cross-shaped spacer box modules (40), and by appropriately using various cross-shaped spacer box modules (40), the axis spacing of the 4-axis auger can be adjusted arbitrarily as shown in FIG. 10.

[0041] FIG. 12 shows a schematic configuration of a two-axis auger type detachable modular auger device connected via a boom (54) linked to the tip of an arm (52) of an excavator (50) as an example according to the present invention.

[0042] Referring to one example in FIG. 12, an auger box module (2) constituting the modular auger device of the present invention is connected to a boom (54) linked to the tip of the arm (52) of an excavator (50) via a link connecting member module (4), and an excavation mixing rod (56) is axially installed on each gear shaft of the auger box module (2), thereby enabling two-axis auger construction on soft ground.

[0043] As described above, the present invention deviates from the conventional concept of being fixed by welding and utilizes expandable modules to diversify the auger arrangement, thereby allowing for assembly and construction regardless of the type of soft ground work by appropriately utilizing the expandable modules without the need to prepare a separate auger.

[0044] Although specific embodiments have been described in the foregoing description of the present invention, various modifications may be made without departing from the scope of the present invention.
