You will build a wall.

Figures 1a to 1d is a schematic partial cross-sectional view of the connection portion of the steel pipe piles, respectively, showing a state in which the conventional steel pipe piles are in contact with each other in the side continuous. As shown in Figs. 1A to 1D, conventional steel sheet piles are made of PP type (type shown in Fig. 1A), LT type (type shown in Fig. 1B), PT type (type shown in Fig. 1C), and HH type. (The form shown in FIG. 1D), the sides thereof are vertically penetrated into the ground in a continuous state in contact with each other. In the P-P type shown in Figure 1a is provided with a pipe-shaped connecting member on the outer surface of the steel tube pile pile, it has a structure to mesh with the pipe-shaped connecting member provided on the outer surface of the neighboring steel pipe pile pile. In the LT type shown in Figure 1b, the connecting member provided on the side of the steel tube pile, the "L-shaped steel" having an L-shaped cross section is made to face each other, the neighboring steel tube pile is made of T-shaped steel A connecting member is provided so that a horizontal portion of the T-shaped steel is disposed in a channel formed in the connecting member of the L-shaped steel. In the PT type shown in Figure 1c is provided with a pipe-shaped connecting member on the side of the steel pipe pile pile, the neighboring steel pipe pile is provided with a connecting member made of T-shaped steel, the horizontal portion of the T-shaped steel pipe It is arranged inside the connecting member of the form. In the HH type shown in Figure 1d is provided with a connecting member of the H-shaped steel on the side of the steel pipe pile, and the adjacent steel pipe pile is provided with a connecting member made of a small H-shaped steel, small inside the H-shaped steel H-shaped steel is arranged.

However, the conventional steel pipe pile side coupling structure shown in Figures 1a to 1d, respectively, is difficult to manufacture and construct due to the complicated shape of the connection portion, in particular, there is a gap between the connection member, simply connecting members overlap each other Arrangement alone does not make perfect order between the steel pipe piles that are next to each other. Therefore, in the prior art, concrete in the connecting member of the L-shaped steel (in the case of Figure 1b), the pipe-shaped connecting member (in the case of Figures 1a and 1c), or the connecting member of the H-shaped steel (in the case of Figure 1d), Filler such as non-shrink mortar must be injected to fill the space between the connecting members.

As a result, such a prior art has to perform additional work called "injection of the filling material" in addition to the mechanical fastening of the connecting member, which not only entails an increase in cost, but also a perfect order through the filling of the filling material. There is a problem that is not made. Furthermore, since the order cannot be expected until the filler is completely cured, there is a problem that it takes a long time until the order function is exhibited.

Not only that, in underwater construction, the filling material injected into the connecting member is leaked to the outside, resulting in water pollution, and the filling material must be used excessively due to the loss of the filling material. Since the filling material is present, when the steel pipe piles are used for temporary construction and then recovered and recycled, drawing the steel pipe piles becomes very difficult, and the recycling of the steel pipe piles is very disadvantageous.

Further, in the conventional steel pipe pile shown in Figures 1a to 1d, the connection member having an L-shaped cross section, the pipe-shaped connecting member, or the H-shaped cross section should be welded and pasted to the steel pipe. Due to the shape of each connecting member, it is very difficult to position and weld the steel pipes so that they do not move. Therefore, the quality control becomes very difficult, such as the possibility of deterioration of welding quality. In order to remove the connecting member, it is difficult to completely remove the welded part, and there is a problem that the degree of recyclability of the steel tube board pile is reduced because the possibility of damage to the steel pipe increases.

Therefore, there is an urgent need for the development of new steel pipe piles and ordered walls using the same.

The present invention was developed in order to solve the above conventional problems, and in particular, it is easier to manufacture than the conventional coupling structure between steel pipe piles, and the construction of the adjacent steel pipe piles are mechanically fastened to each other by using the coupling steel rods. It is excellent in workability and order performance because the steel pipe pile is not detached, and it shows excellent orderability only by mechanical fastening between connecting members so that it does not use the filling material, so it does not cause problems due to the use of the filling material, and it is easy to recycle An object of the present invention is to provide a board pile and an ordered wall using the same.

In the present invention, in order to achieve the above object, as a steel pipe pile for building a water barrier wall used for earth or water barrier construction, consisting of a steel pipe, a member extending in the longitudinal direction of the steel pipe convexly on the outer surface of the steel pipe. It is composed of an insertion member which is provided in a protruding form and a member extending in the longitudinal direction of the steel pipe is provided on the outer surface of the steel pipe, but has a concave space to accommodate the insertion member of the neighboring steel pipe pile pile is inserted It is provided with a steel pipe pile configured to include.

In the steel pipe sheet pile according to the present invention, the outer surface of the insertion member has an opposite horizontal portion, the opposite horizontal portion of the insertion member is the first coupling steel bar for separation prevention and order consisting of steel rods extending in the longitudinal direction of the steel pipe It is provided, the concave space of the receiving member may be configured so that the insertion member of the neighboring steel tube pile pile is inserted and accommodated, among the inner surface of the concave space of the receiving member, the first member provided in the insertion member of the neighboring steel pipe pile pile On the inner surface of the concave space of the receiving member facing the coupling steel bar may further be provided with a second coupling steel bar for separation prevention and order consisting of a steel rod extending in the longitudinal direction of the steel pipe.

Furthermore, in the present invention, the insertion member is composed of a section steel having a cross-section and a vertical section having a 'c' shape, and the first coupling steel rods are provided on the outer surfaces of the two opposing horizontal sections, respectively. Second accommodating steel bars may be provided on the inner side of the concave space facing the two opposite horizontal portions of the insertion member.

In addition, in the steel pipe sheet pile according to the present invention, in the vertical portion of the receiving member is welded to the side of the steel pipe, the welding auxiliary member formed in the form of a rod in advance to the outer surface of the steel pipe in the state of pre-welded welding, in addition to the vertical portion of the receiving member After the side contact with the welding auxiliary member, the welding line is formed in the interval between the vertical portion of the welding auxiliary member and the receiving member and the side of the steel pipe, the receiving member may be provided on the side of the steel pipe.

In the present invention, as a means for achieving the above object, there is provided an ordered wall that is constructed by using the steel sheet pile, the order wall of the present invention, when the sides of the adjacent steel pipe piles are connected to each other, the neighboring The second coupling provided on the inner surface of the receiving member is inserted into the receiving member is inserted into the receiving member, the interval between the first coupling steel bar provided in the insert member of the adjacent steel pipe pile and the steel pipe of the neighboring steel pipe pile pile The steel bar is located, but the second coupling steel bar is characterized in that it has a configuration that is located in close contact with the side of the first coupling steel bar provided in the insertion member of the adjacent steel pipe pile.

In constructing the order wall by continuously connecting the steel pipe pile to the side, unlike the conventional art of joining the side of the steel pipe pile by using a filler such as non-shrink mortar, the present invention does not use the filler, but is provided in the steel pipe pile The coupling between the insertion member and the receiving member, in particular, the mechanical coupling by the side contact between the first coupling steel rod of the insertion member and the second coupling steel rod of the receiving member can achieve a substantial order between the sides of the adjacent steel pipe piles. Is exerted. Therefore, according to the present invention, the additional work of "filling material filling" becomes unnecessary, thereby increasing the working efficiency and reducing the cost when constructing a water barrier, and not having to wait until the filling material is completely hardened. It has the advantage that the order effect is exerted immediately when the board pile is installed in the water or the ground. Furthermore, since the filling material is not used, there is no fear of water pollution due to the external spillage of the filling material when performing the underwater construction, and the increase in the material cost and construction cost by using the filling material and the increase in the construction period due to the filling material curing The effect which can be prevented also is exhibited.

In addition, since the use of the filler is unnecessary in the present invention, it is possible to prevent the difficulty in recycling the steel sheet pile when the filler is used. In particular, in welding attaching the insertion member and the receiving member to the side of the steel pipe, the use of an efficient structure not only facilitates the welding attachment operation, but also facilitates the removal of the insertion member and the receiving member. It is easy to recycle after use.

Furthermore, according to the present invention, since the insertion member, the receiving member, the first coupling steel rod and the second coupling steel rod are installed in the form of protruding shape, it is easy to manufacture the steel pipe pile by simple operation such as welding, and the special It is possible to easily manufacture the steel pipe piles of the present invention by using the ready-made steel pipe products produced in the factory and the channel shape, etc., without cutting or processing work, thereby greatly reducing the time and cost required to produce steel pipe piles. The effect of saving can be achieved.

As an enlarged view corresponding to, an enlarged view showing a state in which the receiving member 12 is welded to the side of the steel pipe 10 using the welding auxiliary member 33 is shown. Throughout this specification, when referring to the steel pipe pile itself, it was marked as "steel pipe pile (1)", when referring to each of the two steel pipe pile piles that are continuously coupled to each other "first steel pipe pile pile (100)" And "second steel tube pile (200)".

As shown in the drawings, the steel pipe pile (1) according to the present invention, consisting of a steel pipe 10 having a circular cross section, a member extending in the longitudinal direction of the steel pipe 10 is convex on the outer surface of the steel pipe (10). Insertion member 11 is provided in a protruding form, and the member is formed to extend in the longitudinal direction of the steel pipe 10 is provided integrally attached to the other outer surface of the steel pipe 10 of the steel pipe pile Insertion member 11 has an open space in a shape corresponding to the outer surface is configured to include a receiving member 12, the insertion member 11 of the adjacent steel pipe pile is inserted and accommodated. On the outer surface of the insertion member 11, the first coupling steel bar 13 for preventing separation and order consisting of a steel bar extending in the longitudinal direction of the steel pipe 10 is provided integrally attached, the first coupling steel bar On the inner surface of the receiving member (12) facing the (13) is also provided integrally attached to the separation prevention and the second coupling steel bar 14 made of steel rods extending in the longitudinal direction of the steel pipe (10).

Looking at the configuration of the insertion member 11 in more detail, the insertion member 11 is provided to protrude from the outer surface of the steel pipe 10, the protruding outer surface of the insertion member 11, there is an opposite horizontal portion, such The first coupling steel bar 13 is provided on the outer surface of the opposite horizontal portion. To this end, in the embodiment shown in the drawing the insertion member 11 is made of a section steel having a 'c' cross section. The section steel of the 'c' cross section constituting the insertion member 11 has two opposite horizontal portions facing each other side by side, and a vertical portion exists across the opposite horizontal portions. In FIGS. 2 and 3, the member number 110 is indicated on the opposite horizontal portion of the insertion member 11, and the member number 112 is indicated on the vertical portion of the insertion member 11. The insertion member 11 may be made of a bent steel in which one plate member is bent, but all or part of the vertical portion and the opposite horizontal portion are each made of a separate plate member, and are joined by welding or the like. It can be made of section steel of section.

As such, the insertion member 11 having a 'c' cross section is formed on the side of the steel pipe 10 long in the longitudinal direction of the steel pipe 10 such that the vertical portion 112 is located toward the adjacent steel pipe pile pile 1. The opposing horizontal portion 110 is integrally attached and coupled by a method such as welding. In FIG. 3, the member number 30 is a welding line 30. The opposite horizontal portion 110 and the vertical portion 112 is not limited to a flat surface, but may be formed of a curved surface, but in the case of the opposite horizontal portion 110, the installation of the first coupling steel bar 13 is convenient. In order to achieve this, it is preferable that the flat surface is formed.

The first coupling steel bar 13 is integrally attached to an outer surface of the opposite horizontal portion 110 of the insertion member 11. The first coupling steel bar 13 is made of a steel bar extending in the longitudinal direction of the steel pipe 10, it is provided on the opposite horizontal portion of the insertion member 11 is integrally attached by a method such as welding. . The surface of the first coupling steel bar 13 may be coated with a watertight material or the like.

In the above description, the insertion member 11 has been exemplified an embodiment made of a section steel having a cross-section and one vertical portion having a 'c' cross section, but in the present invention, the insertion member 11 has two opposite sides. It may also be composed of a member having a square 'ㅁ' cross section having a horizontal portion and two vertical portions. Since the member of the 'ㅁ' cross section is to add one more vertical portion to the member of the 'c' cross section, in relation to the insertion member 11 throughout the present specification, including the description of the claims, 'c' cross section Is to be understood as including not only the letter 'c' but also the cross section of the 'ㅁ' shape. In addition, in the present invention with respect to the insertion member 11, the section steel of the 'c' cross section, it should be understood to include not only the 'b' shaped hollow hollow bending steel, but also made of 'horn' filled with the inner material. do.

However, it is only to be understood that the expression 'c' cross section includes the cross section of the 'ㅁ' shape filled with only the hollow 'ㅁ' shaped cross section. In the case of the receiving member 12 to be described later, the expression 'c' cross section should be understood to be limited to the concave cross-sectional shape of the 'c' shape having two opposite horizontal portions and one vertical portion.

In the present invention, the receiving member 12 is a concave shape member in which the insertion member 11 of the neighboring steel tube pile 1 is inserted and accommodated. As described above, the receiving member 12 has a concave space corresponding to the convex shape of the insertion member 11. Branch may have a cross section and may be formed of a member extending in the longitudinal direction of the steel pipe (10). As illustrated above, when the insertion member 11 has a 'c' cross section having two opposing horizontal portions and one vertical portion, the concave space shape of the accommodating member 12 also corresponds to the 'c' cross section. Has In such a concave space formed in the receiving member 12, the insertion member 11 provided in the adjacent steel pipe pile pile is inserted into the direction perpendicular to the ground. To this end, the receiving member 12 is provided on the outer surface of the steel pipe 10, the outer surface of the vertical portion is integrally attached to the outer surface of the steel pipe 10, such as by welding. Therefore, the open part of the concave space ('c' shaped cross section, in the case of 'c' shaped cross section) is located toward the neighboring steel pipe pile. Like the insertion member 11, the receiving member 12 may be made of a bent steel in which one plate member is bent and manufactured, but all or part of the vertical portion and the opposite horizontal portion are each made of a separate plate member, and thus welded. It can be bonded to the 'c' shaped section steel can be made of.

The first coupling steel bar 13 provided in the insertion member 11 of the adjacent steel pipe pile among the inner surface of the opposite horizontal portion, that is, the opposite horizontal portions facing each other in the 'c' cross section of the receiving member 12; A second coupling steel bar 14 is integrally attached to the opposite horizontal portion of the receiving member 12 facing the inner side of the receiving member 12. The second coupling steel bar 14 may also be integrally attached to the inner surface of the opposite horizontal portion by a method such as welding, and the surface thereof may be coated with a watertight member or the like. In the drawing, the member number 40 is a coating film 40 made of a watertight member or the like coated on the surfaces of the first coupling steel bar 13 and the second coupling steel bar 14.

Steel rods having various cross sections, such as steel rods having a rectangular cross section or steel rods having a circular cross section, may be used as the first coupling steel rods 13 and the second coupling steel rods 14. It is preferable to use a steel bar having a cross section. When the first coupling steel rod 13 and the second coupling steel rod 14 are manufactured by a steel rod having a circular cross section, the first coupling steel rod 13 and the second coupling steel rod 14 move in the length direction thereof, When contacting, it is possible to minimize the damage of the coating film 40, such as a watertight material that is coated on the surface, and accordingly the degree of contact between the sides of the first coupling steel bar 13 and the second coupling steel bar 14 This is because performance can be improved.

Meanwhile, as illustrated in FIG. 6B, in the welding portion 12 of the receiving member 12 having a 'c' cross section, that is, the vertical portion crossing the opposite horizontal portion is welded to the side of the steel pipe 10, as illustrated in FIG. 6B, The welding auxiliary member 33 can also be used. When the diameter of the steel pipe 10 is small, due to the side curvature of the steel pipe 10, there may be a large gap between the outer side of the longitudinal portion of the receiving member 12 and the outer surface of the steel pipe 10. In this case, the welding auxiliary member 33 having a rod shape is welded to the outer surface of the steel pipe 10 in advance, and the welding auxiliary member 33 is in contact with the longitudinal outer surface of the receiving member 12. After that, it is preferable to form the welding line 30 at the interval between the longitudinal portion of the welding auxiliary member 33 and the receiving member 12 and the side surface of the steel pipe 10. Thus, according to the welding joint structure using the welding auxiliary member 33, even if there exists a large space | interval between the outer side of the vertical part of the accommodating member 12, and the outer surface of the steel pipe 10, it can weld easily, and It is possible to reduce the welding amount by preventing the excessive increase in size, and to reduce the cost, and after using the steel pipe pile pile (1) of the present invention as a temporary facility, the receiving member 12 to use it for other purposes Even when separating from the steel pipe 10, the range of the welding wire 30 to be crushed is reduced, so that the receiving member 12 can be easily separated, and the damage of the steel pipe 10 or the receiving member 12 in the process This can be minimized, which is very advantageous in recycling. As the welding auxiliary member 33, it is very advantageous to maximize the above effects by using a steel rod having a circular cross section as illustrated in the drawing.

Next, with reference to Figures 4 to 6a, and 6b will be described with respect to the coupling structure for connecting the steel pipe piles (1) of the present invention as described above, the ordered wall is constructed using the same, and the construction method. Although the expression "order" wall is used in the present specification, the order wall of the present invention is not only used for the purpose of water barrier, but also can be used as a soil barrier for preventing soil, etc. It should be understood to include a retainer.

The outer side surface is also in contact with the inner surface of the longitudinal portion of the receiving member 12, the first coupling steel bar 13 provided on the other opposite horizontal portion of the insertion member 11 is opposite to the other side of the receiving member 12 In contact with the side of the second coupling steel bar 14 provided on the inner portion of the surface is in contact with. In particular, the positions of the second coupling steel bar 14 of the receiving member 12 and the first coupling steel bar 13 of the insertion member 11 are staggered from each other. That is, the second coupling steel bar 14 of the receiving member 12 is located within the gap between the outer surface of the steel pipe and the first coupling steel bar 13 of the second steel pipe pile 200 on one side.

Thus, in the present invention, when the insertion member 11 is inserted into the receiving member 12 between the steel pipe piles arranged adjacent to each other, the first coupling steel rod 13 and the receiving member 12 of the insertion member 11 Sides of the second coupling steel bars 14 are in close contact with each other, and further, one opposite horizontal portion outer surface of the insertion member 11 (the outer surface of the opposite horizontal portion in which the first coupling steel rod does not exist) is formed of the receiving member 12. The inner surface of one of the opposite horizontal portions is in close contact with each other, and the outer surface of the vertical portion of the insertion member 11 is also in close contact with the inner surface of the vertical portion of the receiving member 12. While tightly integrated in one piece, a more perfect degree is achieved at the combined portion.

On the other hand, the receiving member 12 between the outer surface of the steel pipe 10 is provided with the insertion member 11 (the outer surface of the steel pipe forming the second steel tube pile pile indicated in the member number 200 in Figure 6) and the first coupling steel bar (13) Since the second coupling steel bar 14 of the) is positioned between the first coupling steel bar 13 and the second coupling steel bar 14 is a mechanical fastening is made. For example, when the force is applied so that the first steel pipe pile 100 and the second steel pipe pile 200 is far from each other in Figure 6, provided in the insertion member 11 of the second steel pipe pile pile (200). The first coupling steel bar 13 is also intended to move away from the first steel pipe pile 100, the second steel coupling 14 is provided in the receiving member 12 of the first steel pipe pile 100 Since it is located between the outer surface of the steel pipe 10 constituting the (200) and the first coupling steel bar 13, in the mechanical fastening state that the movement of the first coupling steel bar 13 is prevented by the second coupling steel bar (14) Will be. Thus, in the present invention, even if a force is applied to the two adjacent steel pipe piles in a direction away from each other, by the mechanical coupling between the first coupling steel rod 13 and the second coupling steel rod 14 as described above. The resistance force is generated, the two steel pipe piles (1) do not move away from each other to maintain a state in which the side is adjacent. That is, the adjacent steel pipe piles are coupled in a structure that does not deviate from each other, thereby making a solid connection.

Through such a coupling structure, the plurality of steel pipe piles 1 are arranged in a state in which they are continuously coupled to the side, thereby forming the water barrier wall of the present invention for the water barrier.

Next, with reference to FIG. 10, the use of the penetration guide 2 in penetration of the steel pipe pile 1 according to the present invention to the ground will be described.

In constructing the water barrier wall according to the present invention, the steel pipe pile pile 1 is perpendicular to the ground in close contact with the side of the neighboring steel pipe pile already installed, as shown in Fig. 6A, 6B or 9. The penetration guide 2 can also be used for this purpose.

FIG. 10 is a schematic perspective view illustrating a state in which the steel pipe sheet pile 1 is inserted and installed using the penetration guide 2, and the penetration guide 2 is arranged side by side as shown in the drawing. It consists of a fixed beam 21, a movable guide beam 22 orthogonal between the two fixed beams 21, and a gap wedge 23.

The fixed beam 21 may be made of a beam member, such as H-shaped steel, the steel pipe piles (1) are continuously arranged to extend in the direction of the wall, two are installed in parallel at intervals. Side by side spacing between the fixed beams 21 corresponds to the diameter of the steel pipe 10 of the steel pipe pile pile (1). That is, the steel pipe 10 is fitted in the interval between the fixed beam 21. At this time, the outer surface of the steel pipe 10 and the steel pipe 10 so that the outer surface of the steel pipe 10 is in close contact with the fixed beam 21 by eliminating the minute gap existing between the outer surface of the steel pipe 10 and the fixed beam 21. ) The gap wedge 23 can be fitted in the gap between the outer surfaces. The gap wedge 23 may be made of a shock absorber, such as synthetic resin that can absorb the impact generated when driving for penetration of the steel pipe pile (1).

In the fixed beam 21, a plurality of wedge coupling holes may be formed in advance so that the gap wedge 23 may be coupled by a bolt or the like. When the fixed beam 21 is made of H-shaped steel, the above-described wedge coupling hole may be formed in the flange of the H-shaped steel.

The movable guide beam 22 is installed vertically across the pair of fixed beams 21. As shown in the figure, the movable guide beam 22 is provided with a groove 24 into which the receiving member 12 of the steel tube pile pile 1 can be fitted. When the steel pipe pile pile 1 is vertically inserted into the ground, the insertion member 11 provided on one side of the second steel pipe pile pile 200 to be inserted is accommodated in the first steel pipe pile pile 100 already installed. The receiving member 12 provided in the second steel tube pile 200 inserted into the member and inserted into the member is fitted into the groove 24 of the movable guide beam 22. Therefore, when the second steel pipe pile 200 is inserted into the ground is inserted into the ground, it will be stuck in the ground without inclination or departure. After the second steel tube pile 200 is driven, the movable guide beam 22 is separated and moved so as to drive the subsequent steel tube pile, and then coupled to the fixed beam 21 again, subsequent new steel tube pile (1) It serves as a guide to vertical penetration.

End plates 220 are provided at both ends of the movable guide beam 22 to be coupled to the fixed beam 21, and the end plates 220 may be bolted to the flange of the fixed beam 21. . To this end, it is preferable that the bolt coupling holes are formed at intervals in the flange of the fixed beam 21 in advance.

As described above, according to the present invention, the adjacent steel pipe piles (1) are connected to each other at the side, the first coupling steel bar 13 and the outer surface of the insertion member 11 and the inner surface of the receiving member 12, respectively; The insert member 11 is provided with a second coupling steel bar 14 and the insertion member 11 moves vertically to the ground so that the first coupling steel bar 13 and the second coupling steel bar 14 are disposed to abut each other. Since it is inserted into and coupled to the receiving member 12 of the neighboring steel pipe pile, water passes between the insertion member 11 of the steel pipe pile pile and the receiving member 12 of the neighboring steel pipe pile without using a filler as in the prior art. A state of order that cannot be achieved is created. That is, in the present invention, unlike the prior art that joins the side of the steel tube sheet pile (1) by using a filler such as non-shrink mortar, the close coupling between the insertion member 11 and the receiving member 12 provided in the steel tube pile pile, In particular, the mechanical coupling by the side close contact between the first coupling steel rod 13 of the insertion member 11 and the second coupling steel rod 14 of the receiving member 12 is faithful between the sides of the adjacent steel pipe pile (1). It will be able to achieve the order. Therefore, the additional work called "filling material filling" is unnecessary, thereby increasing work efficiency and reducing costs when constructing the order wall, and injecting the steel pipe pile into the water or ground without having to wait until the filling material is completely hardened. It has the advantage that the order effect is exerted immediately after installation. Furthermore, since the filling material is not used, there is no fear of water pollution due to the external spillage of the filling material when performing underwater construction, and it is possible to prevent the increase of material cost, construction cost, and delay in construction period by using the filling material. The effect that there is is exerted.

In addition, since the use of the filler is unnecessary in the present invention, it is possible to prevent the difficulty in recycling the steel sheet pile when the filler is used, and in particular, in the welding and attaching the insertion member and the receiving member to the side of the steel pipe, By using it, the welding attachment operation becomes easier, and the removal of the insertion member and the receiving member is also facilitated, and the use of steel pipe piles in temporary facilities and the like also makes it easier to recycle.

Furthermore, according to the present invention, since the insertion member 11, the receiving member 12, the first coupling steel bar 13 and the second coupling steel bar 14 are installed in a protruding form, they can be used for simple work such as welding. It is easy to manufacture the steel pipe piles, and since the steel pipe board piles of the present invention can be easily manufactured by using the ready-made steel pipe products produced in the factory and products such as channel shapes without any special cutting or processing work, The effect is to significantly reduce and reduce the time and cost required to produce the fabrication.
