Description

  TECHNICAL FIELD The present invention relates to a pile installation jig and a pile installation method, and more particularly, to a pile installation jig and a pile installation method used when installing a pile by inserting a pile into an insertion hole formed in the ground. .

  In recent years, piles made of steel pipe materials (hereinafter referred to as steel pipe piles) are sometimes used as piles installed on the ground to support structures such as photovoltaic panels. Since this steel pipe pile is generally inexpensive, it will be frequently used in the future for installation of solar power generation panels, especially in the construction of a large number of solar power generation panels arranged on a large site, so-called mega solar construction work. There is a possibility that.

  As an installation method of the steel pipe pile, for example, the construction method described in Patent Document 1 is applicable. Explaining this construction method, the steel pipe pile used in this construction method has a spiral projection on its outer periphery and has a pointed tip (lower end), which is buried so as to be screwed into the ground. Is done. As described above, in the construction method described in Patent Document 1, the steel pipe pile is buried at the same time while excavating the ground using the steel pipe pile and installed at a predetermined position.

Japanese Patent No. 5232336

  However, since steel pipe piles have low rigidity compared to normal solid piles, it is considered difficult to apply the above construction method to high-strength (hard) ground. On the other hand, when installing steel pipe piles on hard ground, an insertion hole with a diameter larger than that of the steel pipe piles is drilled in the ground by an auger or the like as a pre-process for burying the piles, and cement milk is poured into the insertion holes. It is effective to install the steel pipe pile by inserting the steel pipe pile.

  However, in the above construction method, since the insertion hole is formed to have a diameter larger than the diameter of the steel pipe pile, the position of the steel pipe pile may be shifted after being inserted into the insertion hole. Such misalignment will affect the construction quality, especially because the structures to be supported are close to each other like mega solar, so the position of steel pipe piles (specifically, the distance between the piles) In cases where accuracy is required, it is considered that this will have a significant effect.

  Then, this invention is made | formed in view of said subject, The place made into the objective is the said insertion hole when inserting and installing the pile for structure support in the insertion hole formed in the ground It is providing the jig | tool and construction method which can suppress the position shift of the pile inserted in.

  According to the pile installation jig of the present invention, the above object is a pile installation jig used when a pile for supporting a structure is inserted and installed in an insertion hole formed in the ground. A jig leg that is detachably disposed with respect to the jig, a jig body that is supported by the jig leg, and is positioned above the insertion hole when the pile installation jig is used, and the jig body A passage hole that passes when the pile is inserted into the insertion hole, and the jig leg has a horizontal upper end surface that surrounds the passage hole in the jig body. The jig body is placed on the ground in such a manner that the locked portion attached to the outer peripheral surface of the pile when the amount of the pile inserted into the passage hole reaches a preset amount. Is solved by restricting the insertion amount by being locked to the upper end surface.

By using the above-described pile installation jig of the present invention, when the pile is inserted into the insertion hole formed in the ground, the pile is inserted through the passage hole formed in the jig installed on the ground. It is inserted into the hole. Then, when the pile is inserted to a predetermined depth, the locked portion attached to the outer peripheral surface of the pile is locked to the upper end surface of the portion located around the passage hole in the jig. It becomes like this. At this time, the jig is set on the ground such that the upper end surface serving as the locking surface is a horizontal plane. Therefore, the pile inserted into the insertion hole is positioned at a predetermined position while maintaining a predetermined posture because the locked portion is locked to the locking surface of the jig.
In addition, since said jig | tool is comprised so that removal is possible with respect to the ground, after installation of a pile is completed, it is removed and it reuses at the time of the pile installation work after the next time. Thus, it becomes possible to procure a jig | tool more easily by setting it as the structure which can reuse a jig | tool, and also it becomes possible to hold down the cost concerning pile installation.

Moreover, said jig | tool for pile installation is used when installing the said pile comprised with a steel pipe, and the said jig | tool main body is comprised by the metal bar body bent so that an annular part may be formed. The passage hole is preferably a hole located inside the annular portion.
If it is said structure, the effect of this invention will become a more meaningful thing. That is, as explained in the section of the problem to be solved by the invention, the method of making an insertion hole in the ground and inserting a pile into the insertion hole is a particularly effective method when a steel pipe pile is used as the pile. If the pile installation jig of the present invention is used in such a construction method, the positional displacement of the steel pipe pile inserted into the insertion hole in the above construction method is suppressed, so it is possible to avoid problems in the above construction method, As a result, it is possible to appropriately install the steel pipe pile while taking advantage of the advantage of using the steel pipe pile.
In addition, if a metal rod, for example, a reinforced concrete perforated beam reinforcing bracket, is used as a material for the jig body, the jig can be easily procured at the construction site.

Also, in the above-mentioned pile installation jig, the jig main body is fitted into the pile so that an arcuate member or a cylindrical member attached to the outer peripheral surface of the pile is detachably attached to the upper end surface. It is even more preferable that the insertion amount is restricted by being locked.
If it is said structure, since the part (namely, to-be-latched part) provided in the pile side in order to be latched by a jig | tool is detachable, installation of a pile was completed like a jig | tool. Later it will be removed and reused during the next pile installation work. In this way, the locked portion can be reused, so that the present invention can be applied to a pile not originally provided with the locked portion, and the cost for installing the pile is further increased. It becomes possible to suppress.

Further, in the above-mentioned pile installation jig, it is more preferable that the upper end surface is brought into contact with a flat surface of the arc-shaped member or the cylindrical member, thereby locking the arc-shaped member or the cylindrical member. It is.
If it is said structure, the latching surface (specifically, the upper end surface of the part around a passage hole) which a jig | tool has will become a horizontal surface, and the to-be-latched surface (Pile side) ( Specifically, since the flat surface which is an arcuate member or one end surface of the tubular member) is locked, the locked state can be maintained satisfactorily. Thereby, it becomes possible to suppress the position shift of the pile inserted in the insertion hole more effectively.

Further, in the above-mentioned jig for pile installation, the jig main body is inserted when the cylindrical member attached in a state of surrounding a part of the outer peripheral surface of the pile is locked to the upper end surface. The amount of insertion is regulated by adjusting the amount of the screw fitted into the through hole formed in the cylindrical member and regulating the amount of protrusion of the screw into the cylindrical member. When the horizontal position of the pile is adjustable, it is more preferable that the passage hole is formed wider than the adjustment range of the horizontal position of the pile.
If it is said structure, after positioning the pile inserted in the insertion hole to the predetermined position in a predetermined attitude | position, it will become possible to finely adjust the position of said pile in a horizontal direction. Thereby, it becomes possible to raise the precision regarding the installation position of a pile more.

The pile installation jig is used when installing the plurality of piles that support a plurality of photovoltaic power generation panels arranged in a row through a gantry. It is good also as the said jig | tool for pile installation common with respect to the said pile of a part.
If it is said structure, the effect of this invention will be exhibited more meaningfully. More specifically, in a system in which a plurality of photovoltaic power generation panels are arranged in a row, that is, in a mega solar system, the photovoltaic power generation panels are densely packed, and thus the positional accuracy of the piles supporting each panel is particularly important. Therefore, the effect which suppresses the position shift of a pile by this invention will be exhibited more meaningfully.
Also, when installing multiple piles that support each panel, using a common jig for some piles (in simple terms, using a jig between piles) It is possible to reduce the cost.

In addition, according to the pile installation method of the present invention, the above-described problem is a pile installation method for installing a pile for supporting a structure by inserting it into an insertion hole formed in the ground. A pile installation jig comprising a jig leg portion that is detachably disposed, a jig body supported by the jig leg portion, and a passage hole formed in the jig body is placed on the ground. A step of inserting the pile through the passage hole and then inserting the pile into the insertion hole, and a step of filling the solidification agent in a space other than the space in which the pile is arranged in the insertion hole. In the step of placing the pile installation jig on the ground, the jig body is located above the insertion hole, and the upper end surface of the part surrounding the passage hole in the jig body is Place the jig leg on the ground so that it is horizontal, and pass the pile through the passage hole. In the step of inserting into the insertion hole, when the amount of the pile inserted into the passage hole reaches a preset amount, the locked portion attached to the outer peripheral surface of the pile is placed on the upper end surface. It is solved by restricting the amount of insertion by locking.
According to the above method, by using the jig described above, the pile inserted into the insertion hole can be positioned at a predetermined position while maintaining a predetermined posture. It becomes possible. In addition, since the above jig is configured to be removable from the ground, it is easy to procure the jig if it is removed after the pile installation is completed and reused during the next pile installation work. Therefore, the cost for installing piles can be reduced.

The pile installation method may further include a step of excavating the ground to form the insertion hole having an opening whose outer edge is wider than the outer peripheral surface of the pile.
In the above case, the effect of the present invention is more meaningfully exhibited. That is, the larger the size of the insertion hole for inserting the pile, the easier the displacement of the pile. On the other hand, even if the hole size is large, by using the method of the present invention, it is possible to suppress the displacement of the pile and to install the pile with high accuracy.

According to the pile installation jig and the pile installation method of the present invention, it is possible to position the pile inserted into the insertion hole at a predetermined position while maintaining a predetermined posture by using the jig. . In addition, since the above jig is configured to be removable from the ground, it can be removed after pile installation is complete and reused during the next pile installation work. This makes it easy to procure jigs and reduce the cost of installing piles.
Due to the above effects, for example, when the present invention is applied when a steel pipe pile is installed on the ground, the steel pipe pile can be accurately installed. In addition, when the present invention is applied when a plurality of photovoltaic power generation panels are arranged in a dense state, each of the plurality of piles can be installed with high accuracy, so that the photovoltaic power generation supported by each pile Even if the panels are arranged in a dense state, they can be accurately arranged at predetermined positions. Furthermore, since it is possible to use a jig between the piles, it is possible to reduce the cost for installation work of the photovoltaic power generation panel.

Hereinafter, an embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the drawings.
In the following, the present embodiment will be described in detail by taking as an example a construction for installing a large number of photovoltaic panels on a predetermined site, that is, a mega solar construction work. In other words, in the following case, a photovoltaic power generation panel is taken as an example of the structure of the present invention, and in particular, installation work of a pile that supports the photovoltaic power generation panel will be described. The present invention is not limited to the construction work of mega solar, but an insertion hole H (see, for example, FIGS. 6 and 7) is drilled in the ground in order to install the pile, and the insertion hole H is piled. As long as it is inserted, it can also be applied to pile installation work for supporting other structures.

  First, in describing the contents of the present embodiment, the pile P according to the present embodiment will be outlined. The pile P according to the present embodiment has an appearance as illustrated in FIG. 1 and is installed on the ground in order to support the photovoltaic power generation panel. More precisely, after the pile P according to the present embodiment is installed on the ground, a gantry (not shown) is also placed on a base plate (not shown) attached to the upper end of the pile P. A photovoltaic power generation panel is attached to the mount. That is, the pile P according to the present embodiment supports the photovoltaic power generation panel via the gantry.

  Further, in the construction work of mega solar, a plurality of photovoltaic power generation panels are installed so as to be arranged in a row, and accordingly, a plurality of piles P are also arranged in a row. In such a situation, in order to arrange each photovoltaic power generation panel with high accuracy, it is necessary to accurately install each pile P at a predetermined position. On the other hand, it becomes possible to install each pile P with high precision in the construction work of the mega solar by the jig 1 according to the present embodiment and the pile installation method using the jig 1. The jig 1 and the pile installation method according to this embodiment will be described in detail later.

  The pile P according to this embodiment will be further described. The pile P is a hollow steel pipe pile. If it demonstrates in more detail, the pile P consists of cylindrical steel pipes, and the front-end | tip (lower end) is a pointed tip. However, the shape and size of the pile P are not particularly limited, and the tip shape may also be a non-pointed shape (for example, an annular flat shape).

  Since the pile P according to this embodiment is hollow as described above, it is lighter than a solid type (hereinafter, solid pile). That is, piles made of steel pipe are superior to solid piles in terms of transportability and cost, but are inferior to solid piles in terms of rigidity. For this reason, about the pile P which concerns on this embodiment, since it becomes difficult to employ | adopt the construction method embedded in the ground, pressing the same pile P, it is assumed that it employs the construction method peculiar to a steel pipe pile and embeds it in the ground. Yes.

  Here, when the construction method peculiar to a steel pipe pile is outlined, before the pile P is buried, an insertion hole H is drilled in the ground by excavating the ground using an auger or the like, and the pile P is inserted into the insertion hole H to a predetermined depth. insert. Thereafter, in the insertion hole H, a space other than the space where the pile P is arranged, specifically, a space between the inner wall surface of the insertion hole H and the outer peripheral surface of the pile P is filled with cement milk as a hardening agent. When the cement milk is hardened, the installation of the pile P is completed.

  By the way, the insertion hole H is formed so that the outer edge of the opening of the insertion hole H is wider than the outer peripheral surface of the pile P so as to be larger than the outer diameter of the pile P. When P is inserted, it is formed in a size that produces play of about 10 to 20 mm. Therefore, when the pile P is simply inserted into the insertion hole H, the position of the pile P may be deviated from the normal position. For this reason, in this embodiment, when the pile P is inserted into the insertion hole H, the jig 1 shown in FIG. 2 is used.

Hereinafter, the jig 1 according to the present embodiment will be described with reference to FIGS.
The jig 1 according to the present embodiment is an example of a pile installation jig according to the present invention, is a substantially trapezoidal component shown in FIG. 2, and mainly includes a metal rod, more specifically, a reinforcing bar member.

  The configuration of the jig 1 will be described. The jig 1 is formed on a jig leg 2, a jig body 3 supported by the jig leg 2, and the jig body 3, as shown in FIG. And a passage hole 4. A pair of jig legs 2 is provided with respect to the jig 1 and has a downward U-shape when the jig 1 is viewed from the side. Further, when the jig 1 is used, each jig leg 2 is placed on the ground. Specifically, as shown in FIG. 5, the tip end ( The lower end is fixed by being slightly pierced into the ground.

  While the jig 1 is being used, the jig leg 2 is placed on the ground with its tip simply pierced into the ground, so when the use of the jig 1 is completed. It can be easily removed from the ground by pulling out the tip. In other words, since the jig leg 2 is detachably arranged with respect to the ground, even the jig 1 once set on the ground is removed from the ground and then reused (in simple terms, use Can be turned).

  Further, in the present embodiment, when the jig 1 is set, the jig legs are arranged such that the upper end surface of the jig body 3 surrounding the passage hole 4 (strictly speaking, the annular portion 5 described later) is a horizontal plane. Part 2 is placed on the ground. In addition, what is necessary is just to utilize well-known means, such as a transit, when setting the jig | tool 1 so that the upper end surface of the annular part 5 may become a horizontal surface.

  The pair of jig legs 2 are attached to both ends of the jig body 3, and the attachment method may be either welding or tightening with a wire or a fastener. Moreover, regarding the attachment of each jig leg part 2, it is good also as having already been attached to the jig | tool main body 3 at the time of being conveyed to a construction site, and the material (for example, reinforcing bar material) in a construction site ), The material may be processed into the shape of the jig leg 2 and attached to the jig body 3.

  The jig body 3 is a part that is set above the insertion hole H when the jig 1 is used and interacts with the pile P when the pile P is inserted into the insertion hole H. An example of the configuration of the jig body 3 according to the present embodiment will be described. The jig body 3 is configured by a metal rod body that is bent so as to form the annular portion 5, specifically, a reinforcing bar member. . More specifically, as shown in FIG. 3, the jig body 3 includes an inner annular portion 5 and an outer annular portion formed by bending one continuous bar for reinforced concrete into a substantially square shape. 6. Here, as shown in FIG. 3, the rod bodies intersect each other at the transition portion from the inner annular portion 5 to the outer annular portion 6 in the jig body 3, and the projection is performed at the intersection. It is welded by welding. Further, both end portions of the rod corresponding to the outer annular portion 6 are bent inward in a substantially U shape and fixed to the inner annular portion 5 by projection welding.

  For the jig body 3 having the above-described structure, a commercially available product can be used as a reinforcing bracket for a reinforced concrete perforated beam. Specifically, it is a MAX WEBREN (registered trademark and product) Name (same below) is available. Thus, the parts constituting the jig body 3 can be procured relatively easily, and therefore, the jig 1 can be easily procured.

  In addition, a hole for passing the pile P, that is, a passage hole 4 is formed inside the inner annular portion 5. The passage hole 4 is formed to be slightly larger than the outer diameter of the pile P, and a portion of the pile P that has passed through the passage hole 4 is inserted into the insertion hole H. That is, the jig 1 is used in a state in which it is set so that the passage hole 4 is positioned at a position immediately above the insertion hole H. When the pile P is inserted into the insertion hole H, it is first inserted through the passage hole 4 and then inserted into the insertion hole H.

  In addition, when using an off-the-shelf commercial product as the jig body 3 as described above, if there are a plurality of variations in the size of the product, the required size of the passing hole 4, in other words, the pile P to be installed It is possible to select an optimal jig body 3 according to the size. Thereby, the construction method (pile installation method) using the jig 1 is rich in versatility.

  Furthermore, when the pile P is inserted into the insertion hole H to a predetermined depth, the jig 1 locks the pile P and restricts the pile P from being further inserted into the insertion hole H. More specifically, when inserting the pile P into the insertion hole H, the vise 10 illustrated in FIG. 4 is attached to a predetermined position in the height direction of the pile P. The vise 10 is an arc-shaped member that is fitted to (clamps) the pile P and is attached to the outer peripheral surface of the pile P. More specifically, the vise 10 is a C-shaped giant clam vise. Further, the vise 10 has an end surface 11 that is a flat surface, and the end surface 11 faces downward when the pile P is inserted into the insertion hole H.

  When the pile P is inserted into the insertion hole H after passing through the passage hole 4, the one end surface 11 of the vise 10 is the same as the upper end surface of the annular portion 5 of the jig body 3 in the jig 1. When the level is reached, one end face 11 of the vise 10 is locked to the upper end face of the annular portion 5 as shown in FIG. That is, the vise 10 is attached to the outer surface of the pile P to form a locked portion, and the jig body 3 is locked to the upper end surface of the annular portion 5 so that the vise 10 is locked. The amount of insertion of the P into the insertion hole H is regulated so as to become a preset regular amount of insertion, in other words, the amount of protrusion of the upper end portion of the pile P protruding above the ground is as designed. regulate.

  More specifically, as shown in FIG. 6, the upper end surface of the annular portion 5 included in the jig main body 3 is adjusted to be a horizontal plane, and in the step of inserting the pile P, When the vise 10 is locked to the end face, the pile P is fixed at that position. Thereby, as shown in FIG. 6, the pile P assumes the attitude | position where the axis line became vertical, and comes to be positioned in this state. And while the engagement state of the upper end surface of the annular part 5 and the vise 10 is maintained, the pile P will be positioned in a predetermined position, maintaining said attitude | position.

  As described above, in the present embodiment, by using the jig 1, it is possible to suppress the displacement of the pile P that is inserted into the insertion hole H. In the present embodiment, the vise 10 has a flat surface on the side that is locked to the upper end surface of the annular portion 5, that is, the one end surface 11. It becomes possible to maintain the locking state between the two. Thereby, the position shift of the pile P is suppressed more effectively. Moreover, since the vise 10 is detachably attached to the pile P, it can be removed from the pile P after the installation work of the pile P is completed and reused for the next installation work of the pile P. Is possible. Thus, by using the detachable vise 10, it becomes possible to apply this invention also to the pile P which is not originally provided with the part latched by the jig | tool 1, and suppresses the cost concerning pile installation. It becomes possible.

  Next, the pile installation method using said jig | tool 1 is demonstrated. The construction using the method, that is, the pile installation work is a step of excavating the ground using an auger to form an insertion hole H having a diameter larger than the outer diameter of the pile P, and placing the jig 1 on the ground. It progresses in order of a step, the step which inserts the pile P in the insertion hole H, and the step which fills the space between the insertion hole H and the pile P with cement milk. In addition, about the step filled with cement milk, it is good also as being implemented before the step which inserts the pile P in the insertion hole H.

In the step of placing the jig 1 on the ground, the jig 1 is set so that the jig main body 3 is positioned above the insertion hole H, and an annular portion in the jig main body 3 using a transit or the like. The jig leg 2 is placed on the ground so that the upper end surface of 5 is horizontal.
Further, when inserting the pile P into the insertion hole H, the vise 10 is clamped at a predetermined position of the pile P and attached to the outer peripheral surface of the pile P. In addition, about the clamp position of the vise 10, the insertion amount (regular insertion amount) of the pile P into the insertion hole H and the level of the jig body 3 when using the jig 1 (height from the ground) Specifically, a position separated from the tip of the pile P by a length corresponding to the sum of the length corresponding to the insertion amount and the length corresponding to the level is set as the clamp position. .

  Thereafter, a step of inserting the pile P into the insertion hole H is performed, and in this step, the pile P to which the vise 10 is attached is inserted into the insertion hole H while passing through the passage hole 4 formed in the jig body 3. To do. When the pile P is inserted into the insertion hole H to a predetermined depth, that is, when the insertion amount reaches the regular insertion amount, the vise 10 is applied to the upper end surface of the annular portion 5 of the jig body 3. It becomes locked. Thereby, the insertion amount of the pile P is regulated and the pile P comes to be positioned. In addition, the vise 10 is locked to the upper end surface of the annular portion 5 of the jig body 3, so that the pile P has a posture along the vertical direction. While the locked state with the main body 3 is maintained, it remains maintained.

  After that, after the cement milk is filled in the space between the insertion hole H and the pile P and until the cement milk is hardened, the posture and position of the pile P are maintained by the jig 1. And installation work of one pile P is completed when cement milk hardens | cures.

  As explained above, in this embodiment, although the pile P is inserted into the insertion hole H that has a larger diameter than the outer diameter of the pile P, the displacement of the pile P is likely to occur. By using the jig 1, it is possible to accurately install the pile P at a predetermined position while suppressing displacement.

  In addition, when the installation work of the pile P is completed, the jig 1 that has been set on the ground is removed and reused in the subsequent work of installing the pile P. Similarly, since the vise 10 described above is also detachably attached to the outer surface of the pile P, it is removed after the installation work of the pile P is completed, and the pile P is installed after the next time. Reused. Thus, in this embodiment, since the jig 1 and the vise 10 as the locked portion are both removable, it can be reused after that (in other words, it can be reused).

  More specifically, in the construction work of mega solar, as described above, a plurality of piles P are installed in a state where a plurality of piles P are arranged in a row, and therefore, the series of steps described above is repeated for each pile P. become. On the other hand, each time the jig 1 and the vise 10 are used, the jig 1 and the vise 10 are set at a predetermined attachment position, and are removed when the installation work of the pile P is completed. Here, in this embodiment, the common jig 1 and the vise 10 are used for some of the piles P among the plurality of piles P. That is, in this embodiment, it is not necessary to prepare the jig 1 and the vise 10 by the same number as the number of piles P, and it is possible to cope with a smaller number. Will reduce the cost of mega solar construction.

  In addition, in the construction work of the mega solar, since the photovoltaic power generation panel, its mount, and the piles P that support them are relatively dense, the positional accuracy at the time of installation of each device or member is particularly important. Therefore, in the construction where the distance between the piles P is relatively short like a mega solar, the construction method using the jig 1, that is, the effect of suppressing the displacement of the piles P by the pile installation method according to the present embodiment. Will be demonstrated more meaningfully.

  Embodiment described above is only one of the structural examples of the jig | tool for pile installation shown in order to make an understanding of this invention easy, and the pile installation method, and does not limit this invention. That is, the present invention can be changed and improved without departing from the gist thereof, and the present invention includes its equivalents.

  Specifically, in the above embodiment, the trapezoidal jig 1 is described as an example. However, the invention is not limited to this, and the jig main body 3 in which the passage hole 4 is formed, and the jig. As long as the jig body 2 is provided with a jig leg 2 for raising the tool body 3 from the ground to a predetermined level, the shape of the jig 1 can be freely designed. May be.

  Moreover, in said embodiment, the arcuate part as a to-be-latched part attached to the outer peripheral surface of the pile P, and the case where the vise 10 is specifically attached to the outer peripheral surface of the pile P was mentioned as an example and demonstrated. However, it is not limited to this, The cylindrical member illustrated in FIG. 7 can be used as the locked member.

  More specifically, the cylindrical member shown in FIG. 7 is an annular sleeve 12 whose inner diameter is somewhat larger than the outer diameter of the pile P, and the pile P is inserted and inserted into the sleeve 12. It is attached to the outer peripheral surface of the pile P. Strictly speaking, the sleeve 12 is formed with three screw holes as through holes at equal intervals along the circumferential direction, and a position adjusting screw 13 (an example of a screw) is provided in each screw hole. It is fitted and its tip protrudes somewhat inside the sleeve 12. And the sleeve 12 is attached to the pile P in the state which enclosed a part of outer peripheral surface of the pile P because the pile P inserted in the inner side is pinched | interposed into the front-end | tips of said position adjustment screw 13. FIG.

  The sleeve 12 has an end surface 14 that is a flat surface, and the end surface 14 faces downward when the pile P is inserted into the insertion hole H. When the pile P passes through the passage hole 4 and is inserted into the insertion hole H, when the insertion amount reaches a preset regular insertion amount, the one end surface 14 of the sleeve 12 is moved to the jig body. 3 is locked to the upper end surface of the annular portion 5. As described above, in the configuration using the sleeve 12 instead of the vise 10, the sleeve 12 is locked to the upper end surface of the annular portion 5, so that the amount of the pile P inserted into the insertion hole H is restricted. Thereby, the pile P will be positioned in a predetermined position, maintaining a predetermined attitude | position.

  Further, in the configuration using the sleeve 12 illustrated in FIG. 7, the amount of insertion into the insertion hole H is regulated by adjusting the amount of protrusion of the position adjusting screw 13 to the inside of the sleeve 12. It is possible to adjust the horizontal position of the pile P. On the other hand, the inner wall surface of the annular portion 5 is configured not to interfere with the pile P whose horizontal position is adjusted by adjusting the amount of protrusion described above with each position adjusting screw 13. In other words, the passage hole 4 is formed such that the outer edge of the opening is wider than the adjustment range of the horizontal position of the pile P.

  Thereby, after positioning the pile P at a predetermined position in a predetermined posture by locking the sleeve 12 to the upper end surface of the annular portion 5 of the jig body 3, the position of the above-mentioned pile is finely adjusted in the horizontal direction. Since it becomes possible, the precision of the installation position of the pile P will improve.
