It relates to a pile reinforcement guide device and its construction method.

In general, in order to construct an underground structure in civil works or building works, a breaker work is performed in which the ground, which is the construction foundation of the structure, is excavated to a certain depth. During excavation construction, if groundwater or infiltrating water elutes into the inside of the foundation site through the excavated ground, the work becomes difficult, and there is a concern that the strength and safety of the structure to be constructed are adversely affected.

Therefore, before performing the foundation digging construction, it is necessary to construct a wall that prevents the groundwater or infiltrate from leaching into the foundation site over the circumference of the improved ground and to prevent the collapse of the ground by the earth pressure generated during the construction.

When the H-beam is inserted into the cylindrical casing, the flange portion of the beam is placed in parallel with the wall surface and is inserted vertically into the center of the cylindrical casing. However, there is a problem that construction errors occur because the H beam is inserted at an inclined angle into the cylindrical casing due to external factors generated during construction.

In order to solve the above problems, a structure for continuous wall construction with a casing and an H-beam guide has been recently registered in Korean Patent Publication No. 10-1861805. This prior art is a technology in which a beam guide is fastened and fixed with bolts to the first and second side frames connected by a connection frame and a space maintaining frame, and an H beam is moved inside the beam guide to be constructed. By moving to, the conventional problem could be solved.

However, in the prior art, since the beam guide is mounted on the upper end of the first and second side frames to guide the vertical movement of the H beam only with the thickness of the beam guide, there is a limitation in accurately guiding the vertical movement of the H beam due to a narrow guide area.

In addition, since the beam guide is fastened and fixed with bolts, the work process is complicated and the work efficiency is low, so there is a problem that the working time is increased.If the beam guide is not firmly fixed by the bolt, flow occurs during the construction of the H beam. There was a problem that accurate construction was difficult because it could be tilted.

In addition, there is a problem in that the construction direction of the H beam cannot be accurately set or confirmed.

1 is a perspective view of a pile reinforcement guide device to which the present invention is applied, and Figure 2 is an exploded perspective view of a pile reinforcement guide device to which the present invention is applied.

The present invention pile reinforcement guide device 100 is installed in the casing 10 inserted into the ground to guide the movement of the pile reinforcement 20 inserted into the ground, the position fixing frame 110, the direction setting unit 120 ) Can be included.

The casing 10 may be a cylindrical steel pipe that is inserted when excavating the ground to prevent the collapse of soil.

The pile reinforcement 20 may be formed of an H-shaped beam, an I-shaped beam, and a square-shaped reinforcing bar.

The position fixing frame 110, as shown in FIG. 3, is inserted and installed in a longitudinal direction so as to contact the inner surface of the casing 10 to guide the pile reinforcement 20 to move vertically without inclining into the casing 10, It may include an upper plate 111 and a lower plate 112, a vertical member 113, a vertical horizontal member 114, a horizontal horizontal member 115.

The upper plate 111 and the lower plate 112 are plate bodies that move along the inner surface of the casing 10. Guide through holes 111 ′ and 112 ′ for guiding the movement of the pile reinforcement material 20 may be formed through the inside of the upper plate 111 and the lower plate 112.

In addition, when the side surfaces of the upper plate 111 and the lower plate 112 are formed with an inclined surface inclined in the moving direction of each plate or a curved curved surface is formed to move into the casing 10, the inner surface of the casing 10 It can reduce friction with a minimum.

The vertical member 113 is configured to connect the upper plate 111 and the lower plate 112 and may be formed in a column shape of a predetermined length. The vertical member 113 may be fixed to the upper plate 111 and the lower plate 112 so as to be located on each side of the guide through holes 111 ′ and 112 ′, but each corner of the guide through holes 111 ′ and 112 ′ It is preferable to be fixed to the upper plate 111 and the lower plate 112 to be located at.

The longitudinal horizontal members 114 are configured to connect the vertical members 113 corresponding in the longitudinal direction, and may be laminated in at least two stages.

The horizontal horizontal member 115 is configured to connect the vertical members 113 corresponding in the horizontal direction, and may be stacked in at least two stages.

In addition, it is possible to connect the longitudinal horizontal member 114 and the transverse horizontal member 115 and the vertical member 113 by the sand member 116. The sand material 116 may further reinforce strength by diagonally connecting the stacked vertical horizontal members 114 and the stacked horizontal horizontal members 115 and the vertical members 113. In addition, the sand material 116 prevents the lower end of the pile reinforcement 20 from being separated from the vertical and transverse horizontal members 114 and 115 to the next vertical and transverse horizontal members 114 and 115, thereby preventing the pile reinforcement 20 Can be guided well in the vertical direction.

The upper plate 111 and the lower plate 112 of the positioning frame 110 are sized to correspond well to the inner surface of the casing 10. Therefore, the position fixing frame 110 is installed in the axial direction of the casing 10, which is a vertical direction, by simply inserting it into the casing 10, and the pile reinforcement 20 can be accurately guided in the vertical direction. In addition, when the length of the casing 10 is long, by coupling the plurality of position fixing frames 110 to each other, the pile reinforcement material 20 having a long length can be accurately installed in a vertical direction. Accordingly, since the pile reinforcement material 20 is accurately positioned at the center of the pile, there is no loss of strength of the pile, and corrosion due to the lack of the coating thickness of the pile reinforcement material 20 is prevented, thereby providing excellent durability.

The direction setting unit 120 is configured to set the construction direction of the pile reinforcement 20 and may include a top plate 121 and a direction setting member 122.

The upper plate 121 is configured to be mounted on the upper surface of the casing 10 and may be formed in a square or circular shape. A guide through hole 121 ′ through which the pile reinforcement material 20 is moved may be formed through the upper plate 121.

The direction setting member 122 may protrude in the same direction as the longitudinal horizontal member 114 on the upper surface of the upper plate 121 to guide the construction direction of the pile reinforcement member 20. In addition, the direction setting member 122 may be formed in a ring shape so that the pile reinforcement guide device 100 by a lifting device can be lifted.

In addition, as shown in Figure 4, further comprises a connection portion 130 for connecting the position fixing frame 110 and the adjacent position fixing frame (110'), the connecting portion 130 is an upper through hole 131, a lower through hole 132, It may include a fixing member 133.

The upper through hole 131 is a through hole formed through the fixing member 133 to be coupled to the lower plate 112 of the position fixing frame 110.

The lower through-hole 132 is a through-hole formed through which the fixing member 133 is coupled to the upper plate 111 of the adjacent position fixing frame 110 ′. The lower through hole 132 may be formed through the upper through hole 131 in the same line.

The fixing member 133 may be installed with an upper through hole 131 and a lower through hole 132 to fix the position fixing frame 110 and the adjacent position fixing frame 110 ′. The fixing member 133 may include a fixing tool coupled with through holes 131 and 132 to protrude an end thereof, and a fixing pin coupled with a pin hole penetrating through the fixing tool. The fixing member 133 may include a bolt coupled through the through hole to protrude an end thereof, and a nut fastened to the bolt.

Next, the manufacturing process of the pile reinforcement guide device configured as described above will be described.

According to the design drawing, the guide through holes 111 ′ and 112 ′ through which the pile reinforcement material 20 is moved are formed to form an upper plate 111 and a lower plate 112 through which the pile reinforcement material 20 is moved. The upper plate 111 and the lower plate 112 may be formed in the same shape as the inner surface of the casing 10. That is, it may be formed in a circular shape so as to contact the inner surface of the casing 10.

In addition, four vertical members 113 connecting the upper plate 111 and the lower plate 112 are formed. The vertical member 113 is manufactured to have a predetermined length, and may be connected and fixed to each corner of the guide through holes 111 ′ and 112 ′ of the upper plate 111 and the lower plate 112. At this time, the inner surface of the vertical member 113 may be positioned on the same line as the inner surface of the guide through holes 111 ′ and 112 ′ so that the pile reinforcement member 20 may contact and move.

Of the four vertical members 113, the vertical horizontal member 114 is connected and fixed to the vertical member 113 facing in the vertical direction, and the horizontal horizontal member 115 is connected and fixed to the vertical member 113 facing in the horizontal direction. Fixing frames 110 and 110 ′ may be manufactured

Here, the vertical horizontal member 114 and the horizontal horizontal member 115 may be laminated in at least two stages, and the vertical horizontal member 114 and the horizontal horizontal member 115 are preferably located on the same horizontal line, The longitudinal horizontal member 114 may be positioned to be higher or lower than the transverse horizontal member 115.

And it is possible to reinforce the strength of the vertical member 113 by diagonally connecting the horizontal member 114 in the longitudinal direction and the horizontal member 115 and the vertical member 113 in a diagonal line with the thread member 116. This is because the reinforcing force can be further increased than when the sand material 116 is connected and fixed horizontally or vertically.

On the other hand, after the upper plate 121 on which the direction setting member 122 of the direction setting unit 120 is protruded is mounted on the upper surface of the upper plate 111, the upper plate 111 and the upper plate 121 may be fixed. . The upper plate 111 and the upper plate 121 may be fixed by welding, or the upper plate 111 and the upper plate 121 may be fixed by fastening bolts/nuts. A through hole may be formed in the upper plate 121 in the same line as the lower through hole 132 formed through the upper plate 111 so that the bolt is coupled.

The direction setting member 122 may be formed to protrude from the upper plate 121 so as to be formed in the same direction as the longitudinal horizontal member 114. Since it is possible to easily set the construction direction of the pile reinforcement material 20 in the direction indicated by the direction setting member 122 while rotating the upper plate 121, the working time can be shortened by improving work efficiency and shortening the work process.

The position fixing frame 110 may be connected to a neighboring position fixing frame 110 ′ and a connection part 130 according to a length inserted into the casing 10. The lower plate 112 of the positioning frame 110 and the upper plate 111 of the adjacent positioning frame 110 ′ are positioned on the same line so that they are in close contact with each other. In this case, the upper through hole 131 formed through the lower plate 112 and the lower through hole 132 formed through the upper plate 111 may be located on the same line.

The fixing member 133 may be installed in the upper through hole 131 and the lower through hole 132 to connect and fix the position fixing frame 110 and the adjacent position fixing frame 110 ′. The fixing member 133 may be fixed by combining the fixing pin with a fixing tool in which an end protrudes and a pin hole of the protruding fixing part by being coupled to the upper through hole 131 and the lower through hole 132. In addition, the fixing member 133 may be fixed by fastening a bolt to the protruding end and a bolt that is coupled to the upper through hole 131 and the lower through hole 132 to protrude the end.

By repeating the above process, a plurality of other adjacent position fixing frames may be connected and fixed to the neighboring position fixing frames 110 ′.

As described above, it is possible to manufacture the pile reinforcement guide device 100 in which the position fixing frame 110 is fixed to the direction setting unit 120, and a plurality of position fixing frames 110 and 110 ′ are provided in the direction setting unit 120 The pile reinforcement guide device 100 connected to the connection part 130 may be manufactured.

The following describes the construction process of the earthing wall using the pile reinforcement guide device 100 manufactured by the above process.

As shown in FIG. 6, as shown in FIG. 6, the casing 10 is inserted and installed in the drilling hole while forming a drilling hole in the ground with an excavation equipment. A guide wall for guiding the insertion of the casing 10 may be formed at the upper end of the perforated hole.

The casing 10 may be inserted and installed in the casing 10 while drilling the perforated hole by a screw auger.

When the casing 10 is inserted and installed in the perforated hole, as shown in FIG. 7, a ring of a lifting device (not shown) is hung on the direction setting member 122 of the direction setting unit 120, and a pile reinforcement guide device with the lifting device ( 100) is lifted and positioned above the casing 10, and in this state, the pile reinforcement guide device 100 is moved downward and inserted into the casing 10.

At this time, the side of the upper plate 111 of the position fixing frame 110 ′ adjacent to the position fixing frame 110 ′ of the pile reinforcement guide device 100 is formed with an inclined surface inclined in the moving direction of the upper plate or a curved curved surface. (10) Since friction with the inner surface can be reduced to a minimum, the pile reinforcement guide device 100 can be smoothly moved and inserted into the casing 10.

When the adjacent position fixing frame 110 ′ and the position fixing frame 110 are inserted into the casing 10 to a certain depth, the bottom surface of the upper plate 121 of the direction setting part 120 fixed to the upper end of the position fixing frame 110 is the casing (10) Insertion movement stops while seating on the upper surface.

At this time, since the side of the upper plate 111 and the lower plate 112 of the position fixing frame 110 and the adjacent position fixing frame 110 ′ are in contact with the inner surface of the casing 10, the position fixing frame 110 and the adjacent position fixing frame ( 110') can be prevented.

In addition, as shown in FIG. 8, the upper plate 121 seated on the upper surface of the casing 10 is rotated in a forward or reverse direction by a lifting device (not shown). At this time, since the direction setting member 122 protruding on the upper surface of the upper plate 121 can easily indicate the construction direction of the pile reinforcement 20 while moving with the rotation of the upper plate 121, the construction direction of the pile reinforcement 20 Can be set easily, so the working time can be shortened.

As the upper plate 121 rotates, the position fixing frame 110 fixed to the upper plate 121 and the sides of the upper plate 111 and the lower plate 112 of the neighboring position fixing frame 110 ′ come into contact with the inner surface of the casing 10 While rotating, the guide holes 111 ′ and 112 ′ of the upper plate 111 and the lower plate 112 are positioned in the direction set by the direction setting member 122.

When the direction of the direction setting member 122 is set by the above process, the ring of the lifting equipment (not shown) is separated from the direction setting member 1220, and as shown in FIGS. 9 to 10, an H-shaped beam and an I-shaped After lifting the pile reinforcement material 20 of the beam or the reinforcing bar with a lifting device (not shown) and moving it to the upper guide hole 121 ′ of the top plate 121, the pile reinforcement material 20 is moved downward.

The pile stiffener 20 sequentially passes through the guide through holes 121 ′ of the top plate 121 and the guide through holes 111 ′ of the top plate 111, and then the vertical members 113, the longitudinal and horizontal members 114 in the transverse direction. It moves downward along the inner surface of the horizontal member 115 and passes through the guide through hole 112 ′ of the lower plate 112 again.

In addition, the lower end of the pile reinforcement 20 is positioned at the bottom of the casing 10 while passing through the guide through hole 111 ′, the vertical member 113 and the guide through hole 112 ′ of the adjacent position fixing frame 110 ′ in sequence. Then, the lifting equipment fixed to the pile reinforcement 20 can be separated, and the upper end of the pile reinforcement 20 is hit with a striking member so that the lower end is embedded in the rock layer and fixed. At this time, the pile reinforcement material 20 is located in the center of the casing 10 while accurately moving vertically without inclining along the inner surface of the pile reinforcement guide device 100, and the durability is not damaged due to the difference in the thickness of the concrete cover poured below. Strength and safety can be ensured.

When the lower end of the pile reinforcement material 20 is embedded and fixed in the rock layer, as shown in FIG. 11, concrete can be poured into the casing 10. When the concrete upper surface to be poured is sequentially moved from the lower end of the casing 10 to the upper end, the hook of the lifting device is hooked on the direction setting member 122 of the direction setting part 120, and the pile reinforcement guide device 100 by the lifting device Can be stored separately from the casing (10).

At this time, the side of the lower plate 112 of the position fixing frame 110 and the adjacent position fixing frame 110 ′ is formed with an inclined or curved curved surface inclined in the moving direction of the lower plate to reduce friction with the inner surface of the casing 10 to a minimum. Therefore, the pile reinforcement guide device 100 can be smoothly moved to the outside and withdrawn.

When the pile reinforcement guide device 100 is withdrawn from the casing 10, concrete is even poured into the casing 10, and the casing 10 is lifted with a lifting device (not shown) and separated from the ground, as shown in FIG. Likewise, piles can be formed by cured concrete. The casing 10 may be lifted while concrete is poured.

The piles adjacent to each other through the above process may be sequentially formed at a location spaced apart from the pile by a predetermined distance. A female pile without the pile reinforcement 20 is first formed between the pile and the adjacent pile, and a male pile with the pile reinforcement 20 installed so as to overlap with these female piles can be constructed.

A pile reinforcement material 20 is installed on the female pile to be constructed first at a predetermined interval, and a circular reinforcing bar network reinforced with a band reinforcement or spiral reinforcement may be installed in the male pile to be constructed later while partially cutting the female pile.

In addition, a pile reinforcement material 20 may be installed on the female piles that are constructed at regular intervals, and a circular reinforcing bar network may be installed on the male piles constructed while partially cutting the female piles.

By repeating the process of placing the piles in the cut portion of the piles, the wall W may be formed as shown in FIGS. 13A to 13C. In addition, it is possible to form a wall (W) by constructing an overlapping pile between the pile and the adjacent pile. In addition, by installing a separate water barrier between the piles and the stacked piles, it is possible to prevent the ordering so that groundwater, etc., cannot penetrate through the gaps in the wall.

In addition, since concrete can be placed on the inner surface of the wall (W) to form the basement outer wall of the structure, the use of raw materials is reduced due to the reduction of the wall thickness than when forming the basement outer wall of the structure inside the wall. And, as the space expands, the utilization of the space can be increased.

In addition, it is possible to construct the piles of the overlapping column pile wall by the construction method of the pile reinforcement guide device of the present invention. That is, in an overlapping column pile wall including a female pile constructed at a certain interval and a male pile constructed while partially cutting the female pile, the female pile is constructed, the male pile is constructed, the female pile and the male All piles can be constructed. In addition, only some of the piles can be selectively constructed by the construction method of the pile reinforcement guide device of the present invention.
