Description

[Technical Field]

[0001] The present invention relates to a jig for a pile body and a pile body. [Background technology]

[0002] For example, at the site of a river channel closure, it is necessary to use a submersible pump to quickly drain the water to prevent secondary disasters. Driving multiple piles into the ground manually with a hammer or other tool to fix the position of the hose extending from the submersible pump places a great burden on the worker. For this reason, a dedicated jig for installing piles into the ground using construction machinery has been considered (see, for example, Patent Document 1). The dedicated jig described in Patent Document 1 is attached to the top of a pile driven into the ground, and the bucket of a hydraulic excavator is placed on the pressure base of the dedicated jig. The bucket is then moved downward to drive the pile into the ground via the dedicated jig. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-336260 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the method using the dedicated jig described in Patent Document 1, before driving the pile with construction machinery, the pile must be manually transported to the installation site, temporarily driven into the ground by hand, and the dedicated jig must be attached to the head of the pile.In addition, when removing the pile, the pile must be manually pulled out of the ground using a removal jig.

[0005] The present invention has been made in consideration of the above points, and aims to provide a pile jig and a pile that can be transported, installed, and removed using construction machinery. [Means for solving the problem]

[0006] One embodiment of the pile body jig of the present invention is a pile body jig for installing a pile body in the ground using a construction machine, and comprises an attachment part that is detachably attached to the head of the pile body, a lower member that extends outward in the pile diameter direction from the attachment part, and an upper member that faces the lower member from above in the pile axial direction, and the distance between the lower member and the upper member is formed to be large enough to allow the working claws of the construction machine to enter. [Effects of the Invention]

[0007] In one embodiment of the pile jig of the present invention, the pile is transported by inserting the work claw between the lower and upper members. The pile is pre-driven into the ground by pushing the lower member with the work claw, and the pile is driven into the ground permanently by pushing the upper member with the work claw. The pile is also pulled out of the ground by pulling up the upper member with the work claw. In this way, by attaching the pile jig to the head of the pile, the pile can be transported, installed, and removed using a single construction machine. [Brief explanation of the drawings]

[0009] The pile body jig of this embodiment will be described below. Figure 1 is a perspective view of the pile body jig and the pile body of this embodiment. Note that Figure 1(A) shows the pile body jig and the pile body separated, and Figure 1(B) shows the pile body jig attached to the pile body.

[0010] As shown in Figures 1(A) and 1(B), the pile body 10 is formed by narrowing the upper and lower sides of a cylindrical steel pipe. A cylindrical pile body 11 is formed in the middle part of the pile body 10. A conical head 12 is formed on the upper side of the pile body 11. An inverted cone-shaped tip 13 is formed on the lower side of the pile body 11. The pile diameter of the tip 13 becomes smaller toward the bottom, which makes it easier for the tip 13 to penetrate into the ground without disturbing the ground during pile driving.

[0011] The pile body jig 20 is used to install the pile body 10 using a hydraulic excavator 30 (see FIG. 2). The pile body jig 20 has a cylindrical mounting portion 21 formed therein. The lower end of the mounting portion 21 is open, and the head 12 of the pile body 10 is inserted into the inside of the mounting portion 21. A pair of nuts 25 are welded to the outer circumferential surface of the head 12 of the pile body 10, and a pair of through holes 26 are formed in the mounting portion 21 to correspond to the pair of nuts 25. The head 12 of the pile body 10 is inserted into the mounting portion 21, and a pair of bolts (not shown) are tightened into the pair of nuts 25 through the pair of through holes 26, whereby the mounting portion 21 is detachably attached to the head 12 of the pile body 10.

[0012] A rectangular lower plate (lower member) 22 perpendicular to the pile axis direction is provided below the mounting portion 21, and a rectangular upper plate (upper member) 23 parallel to the lower plate 22 is provided at the upper end of the mounting portion 21. The lower plate 22 projects outward from the mounting portion 21 in the pile radial direction, and the upper plate 23 faces the lower plate 22 from above in the pile axis direction. The distance between the lower plate 22 and the upper plate 23 is formed to be large enough to allow the work claw 32 (see Figure 2) protruding from the bucket 31 to fit in. The center of the lower plate 22 and the center of the upper plate 23 are connected via the mounting portion 21, and the work claw 32 passes beside the mounting portion 21 and fits between the lower plate 22 and the upper plate 23.

[0013] The work claws 32 fit between the flat plates of the lower plate 22 and the upper plate 23, and the attachment parts 21 fit between the multiple work claws 32, making it difficult for the pile body jig 20 to come off the work claws 32. In addition, magnets 24, such as neodymium magnets, are provided on the underside of the upper plate 23 on both sides of the attachment parts 21. The work claws 32 are attracted to the upper plate 23 by the magnetic force of the magnets 24, making it even more difficult for the pile body jig 20 to come off the work claws 32 due to external factors such as vibrations during transportation of the pile body 10. In this way, the pile body jig 20 is attached to the pile body 10 and hooked onto the work claws 32, allowing the hydraulic excavator 30 to transport, install, and remove the pile body 10.

[0014] The operations of transporting, installing, and removing the pile body will be described with reference to Figures 2 and 3. Figures 2 and 3 are explanatory diagrams of the operations of transporting, installing, and removing the pile body in this embodiment. Note that Figure 2(A) shows the operation of transporting the pile body, Figure 2(B) shows the operation of temporarily driving the pile body, Figure 2(C) shows the operation of actually driving the pile body, and Figure 2(D) shows the operation of removing the pile body.

[0015] As shown in FIG. 2(A), the pile body 10 is transported by a hydraulic excavator 30 via a pile body jig 20. In this case, the working claws 32 of the bucket 31 enter between the lower plate 22 and the upper plate 23 of the pile body jig 20, and the mounting parts 21 of the pile body jig 20 enter between adjacent working claws 32, thereby hooking the pile body jig 20 onto the working claws 32 (see FIG. 2(B)). In addition, the upper plate 23 of the pile body jig 20 is held to the working claws 32 by the magnetic force of the magnets 24. With this structure, even if the hydraulic excavator 30 moves over uneven ground and vibrations or the like occur in the working claws 32, the pile body jig 20 will not come off the working claws 32, and the pile body 10 can be transported to a desired installation position.

[0016] As shown in Figure 2(B), once the pile body 10 is positioned at the desired installation position, the hydraulic excavator 30 temporarily drives the pile body 10 into the ground. In this case, the lower plate 22 of the pile body jig 20 is pushed downward by the working claw 32 of the bucket 31, and the tip 13 of the pile body 10 penetrates shallowly into the ground via the pile body jig 20, thereby driving the pile body 10 into the ground. Because the pile body 10 is held by the working claw 32 by the pile body jig 20, there is no need to manually support the pile body 10 when temporarily driving it into the ground. In other words, because the working claw 32 is inserted between the lower plate 22 and the upper plate 23 of the pile body jig 20, the pile body 10 can be driven into the ground while being positioned at the desired installation position.

[0017] As shown in Figure 2(C), after the pile body 10 has been temporarily driven into the ground, the pile body 10 is driven into the ground by a hydraulic excavator 30. In this case, the working claw 32 of the bucket 31 is pulled out from between the lower plate 22 and the upper plate 23 of the pile body jig 20, and then the working claw 32 is brought into contact with the upper plate 23 of the pile body jig 20 from above. The upper plate 23 of the pile body jig 20 is pushed downward again by the working claw 32, and the tip 13 of the pile body 10 penetrates deep into the ground via the pile body jig 20, and the pile body 10 is buried. By repeating a series of operations from transporting the pile body 10 to driving it into the ground, multiple pile bodies 10 can be installed at desired positions in the ground without relying on human power.

[0018] As shown in FIG. 2(D), the pile body 10 is removed by the hydraulic excavator 30 via the pile body jig 20. In this case, the working claws 32 of the bucket 31 enter between the lower plate 22 and the upper plate 23 of the pile body jig 20, and the mounting parts 21 of the pile body jig 20 enter between adjacent working claws 32, thereby hooking the pile body jig 20 onto the working claws 32. The upper plate 23 of the pile body jig 20 is lifted upward by the working claws 32 of the bucket 31, and the tip 13 of the pile body 10 is pulled out from the ground via the pile body jig 20. By hooking the working claws 32 onto the pile body jig 20, the pile body 10 can be pulled out of the ground via the pile body jig 20 without using a removal jig.

[0019] 3, a plurality of storage tubes 36 may be installed on an off-road vehicle 35, and a plurality of pile bodies 10 may be transported to the work site of the hydraulic excavator 30. In this case, it is preferable that a holding member (not shown), such as a sponge, is provided inside the plurality of storage tubes 36, and the plurality of pile bodies 10 inserted into the plurality of storage tubes 36 are held by the holding member. The frictional force of the holding member restricts irregular movement of the plurality of pile bodies 10 during transportation, and the plurality of pile bodies 10 are transported to the work site of the hydraulic excavator 30 with their orientations aligned. This makes it easier for the hydraulic excavator 30 to remove the pile bodies 10 from the storage tubes 36, improving the workability of the pile body 10 installation work.

[0020] As described above, according to the pile body jig 20 of this embodiment, the pile body 10 is transported by inserting the work claw 32 between the lower plate 22 and the upper plate 23. The pile body 10 is pre-driven into the ground by pushing the lower plate 22 with the work claw 32, and the pile body 10 is driven into the ground permanently by pushing the upper plate 23 with the work claw 32. The pile body 10 is also pulled out of the ground by pulling up the upper plate 23 with the work claw 32. In this way, by attaching the pile body jig 20 to the head 12 of the pile body 10, the pile body 10 can be transported, installed, and removed using a single hydraulic excavator 30.

[0021] In this embodiment, the pile body jig is formed so that the lower plate and the upper plate are connected by the attachment portion, but the shape of the pile body jig is not particularly limited. For example, as shown in a modified example in FIG. 4(A), the pile body jig 40 may be formed by connecting both ends of a rectangular lower plate 42 and both ends of a rectangular upper plate 43 with a pair of side plates 44. In this case, the work claw 32 (see FIG. 2) passes through the inside of the pair of side plates 44 and enters between the lower plate 42 and the upper plate 43, and the work claw 32 enters into the frame formed by the lower plate 42, the upper plate 43, and the pair of side plates 44, and the pile body jig 40 is hooked. The pile body jig 40 is less likely to come off the work claw 32, improving the workability of transporting the pile body 10.

[0022] Furthermore, for example, as shown in a modified example in FIG. 4(B), the pile body jig 50 may be formed by connecting the corners of a triangular lower plate 52 and the corners of a triangular upper plate 53 with three connecting portions 54. In this case, the work claws 32 (see FIG. 2) pass between adjacent ones of the three connecting portions 54 and enter between the lower plate 52 and the upper plate 53 to hook the pile body jig 50. The work claws 32 can be inserted into the pile body jig 50 from three directions, making it easy to hook the pile body jig 50 with the work claws 32. The shapes of the upper plate 53 and the lower plate 52 are not particularly limited, and the upper plate 53 and the lower plate 52 may be formed into a polygon with more than one side. Furthermore, the multiple connecting portions 54 do not necessarily connect the corners of the lower plate 52 and the upper plate 53, but may connect the outer edges of the lower plate 52 and the upper plate 53.

[0023] Furthermore, for example, as shown in a modified example in FIG. 4(C), the pile body jig 60 may be formed by connecting the center of a circular lower plate 62 and the center of a circular upper plate 63 with an attachment portion 61. In this case, a screw may be attached to the tip end 66 side of the pile body 65. When the pile body jig 60 is pushed in by the hydraulic excavator 30, the pile body 65 is driven into the ground while rotating together with the pile body jig 60. Because the pile body jig 60 is rotatably hooked to the working claw 32 of the bucket 31, the rotation of the pile body 65 is not restricted by the working claw 32 and the pile body jig 60.

[0024] Furthermore, although the distance between the lower plate and the upper plate is fixed in this embodiment, the distance between the lower plate and the upper plate may be adjustable. For example, as shown in Fig. 5, a rectangular lower plate 93 and an upper plate 94 of a pile body jig 90 are separated, and cylindrical mounting portions 91 and 92 protrude from the lower plate 93 and the upper plate 94, respectively. The upper plate 94 is attached to the head of a pile body 95, and by changing the mounting position of the lower plate 93 relative to the pile body 95, the distance between the lower plate 93 and the upper plate 94 can be adjusted to match the size of the work claw 32. The same pile body jig 90 can be used for hydraulic excavators 30 of all sizes, from small to large.

[0025] Furthermore, in this embodiment, the pile body jig and the pile body are formed as separate bodies, but the pile body jig and the pile body may be formed as an integral unit. For example, as shown in FIG. 6, the pile body 70 itself may be hooked onto a hydraulic excavator 30 (see FIG. 2) and installed in the ground. In this case, the pile body 70 is driven into the ground with the tip 75 of the pile body 71 of the pile body 70 facing downward and the head 72 facing upward, and a lower plate 73 extends outward from the head 72 in the pile radial direction, and an upper plate 74 faces the lower plate 73 from above in the pile axial direction. The gap between the lower plate 73 and the upper plate 74 is formed to be large enough to allow the work claw 32 to enter. Even with this configuration, the pile body 70 can be transported, installed, and removed using a single hydraulic excavator 30.

[0026] The pile body may also be used as a support pile for another installed object. For example, as shown in FIG. 7(A), a traffic cone 81 may be supported by a pile body 80. The traffic cone 81 can be transported, installed, and removed by a hydraulic excavator 30 via a pile body jig 82 attached to the pile body 80. Furthermore, as shown in FIG. 7(B), an anti-aircraft sign 86 may be supported by a pile body 85. The traffic cone 86 can be transported, installed, and removed by a hydraulic excavator 30 via a pile body jig 87 attached to the pile body 85. In this case, the pile body, the installed object, and the pile body jig may be formed integrally, or may be formed separately.

[0027] In addition, in this embodiment, a hydraulic excavator is used as an example of the construction machine, but the construction machine may be a rotary fork or a wheel loader as long as it has a working claw that can hook the pile body jig.

[0028] In this embodiment, the pile body is formed by narrowing the upper and lower sides of a cylindrical steel pipe, but the pile body may be formed in a rod shape that can be driven into the ground. For example, the pile body may be formed from a solid rod material. Furthermore, the shape of the upper side of the pile body is not limited to a cone shape, and the shape of the lower side of the pile body is not limited to an inverted cone shape, and the pile body may be formed from a cylindrical steel pipe such as a single pipe.

[0029] In addition, in this embodiment, a plurality of storage tubes for pile bodies are installed on the off-road transport vehicle, but a plurality of storage tubes may be installed on another transport vehicle having a surface for installing storage tubes. For example, a plurality of storage tubes may be installed on a vessel such as a dump truck.

[0030] In addition, in this embodiment, the mounting portion of the pile body jig is screwed to the head of the pile body, but the method of mounting the mounting portion of the pile body jig to the head of the pile body is not particularly limited.

[0031] In addition, although the present embodiment illustrates a lower plate as an example of the lower member, the lower member may be formed so as to protrude outward from the mounting portion in the radial direction of the pile. For example, the lower member may be formed in a pole shape.

[0032] In addition, in this embodiment, an upper plate is exemplified as the upper member, but the upper member may be formed so as to face the lower member from above in the pile axial direction. For example, the upper member may be formed in a pole shape.

[0033] As described above, the first aspect is a pile jig (20, 40, 50, 60, 90) for installing a pile (10, 65, 95) in the ground using a construction machine (hydraulic excavator 30), and includes an attachment portion (21, 41, 51, 61, 91, 92) that is detachably attached to the head of the pile, a lower member (lower plate 22, 42, 52, 62, 93) that extends outward in the pile radial direction from the attachment portion, and an upper member (upper plate 23, 43, 53, 63, 94) that faces the lower member from above in the pile axial direction, and the distance between the lower member and the upper member is large enough to allow the work claw (32) of the construction machine to enter between the lower member and the upper member. According to this configuration, the pile is transported by the work claw entering between the lower member and the upper member. The pile is pre-driven into the ground by pushing the lower member with the work claw, and the pile is driven into the ground permanently by pushing the upper member with the work claw. The pile is then pulled out of the ground by pulling up the upper member with the work claw. By attaching the pile jig to the head of the pile in this way, the pile can be transported, installed, and removed using a single construction machine.

[0034] In the second embodiment, in the first embodiment, the upper member is provided with a magnet 24. With this configuration, the working claw is attracted to the upper plate by the magnetic force of the magnet, making it difficult for the pile body jig to come off the working claw due to external factors such as vibration during transportation of the pile body.

[0035] In the third aspect, in the first or second aspect, the lower member is a lower plate (22, 42, 52, 62) perpendicular to the pile axis direction, and the upper member is an upper plate (23, 43, 53, 63) parallel to the lower plate. With this configuration, the working claw can get in between the flat plates of the lower plate and the upper plate, making it difficult for the pile body jig to come off the working claw.

[0036] In the fourth aspect, in the third aspect, the mounting portion (21) connects the center of the lower plate and the center of the upper plate, and the working claw passes along the side of the mounting portion and enters between the lower plate (22) and the upper plate (23). With this configuration, the mounting portion enters between the working claws, making it difficult for the pile body jig to come off the working claw. In addition, the pile body jig can be formed compactly.

[0037] The fifth aspect is the third aspect, which is provided with a pair of side plates (44) connecting both ends of the lower plate (42) and both ends of the upper plate (43), and the working claw passes through the inside of the pair of side plates and enters between the lower plate and the upper plate. With this configuration, the working claw enters into a frame consisting of the lower plate, the upper plate, and the pair of side plates, and the pile body jig is hooked. In addition, it is possible to make it difficult for the pile body jig to come off the working claw.

[0038] The sixth aspect is the third aspect, which is provided with a plurality of connecting portions (54) connecting the outer edge portion of the lower plate (52) and the outer edge portion of the upper plate (53), and the working claw passes between adjacent connecting portions among the plurality of connecting portions and enters between the lower plate and the upper plate. With this configuration, the working claw enters between adjacent connecting portions to hook the pile body jig. Also, the working claw can be inserted into the pile body jig from a plurality of directions.

[0039] The seventh aspect is a pile body (70) that is installed in the ground using a construction machine. The pile body (71) includes a pile body (71) that is driven into the ground with its head (72) facing upward, a lower member (lower plate 73) that extends outward from the head in the pile radial direction, and an upper member (upper plate 74) that faces the lower member from above in the pile axial direction. The distance between the opposing lower member and upper member is large enough to allow the work claw of the construction machine to enter between them. According to this configuration, the pile body is transported by the work claw entering between the lower member and the upper member. The pile body is pre-driven into the ground by pushing the lower member with the work claw, and the pile is finally driven into the ground by pushing the upper member with the work claw. The pile body is also pulled out of the ground by pulling up the upper member with the work claw. In this way, the pile body can be transported, installed, and removed using a single construction machine.

[0040] Although the present embodiment and modifications have been described, other embodiments may be obtained by combining the above-described embodiments and modifications in whole or in part.

[0041] Furthermore, the technology of the present invention is not limited to the above-described embodiments, and may be variously changed, substituted, or modified within the scope of the spirit of the technical idea. Furthermore, if the technical idea can be realized in a different way due to technological advances or other derived technologies, it may be implemented using that method. Therefore, the claims cover all embodiments that may fall within the scope of the technical idea. [Explanation of symbols]
