When the insertion jig 40 is inserted into the guide pipe 8 or 9, the air trapped between the pedestal 41 and the bottom 9 </ b> A is released by the air vent hole 46, whereby the insertion jig 40 is connected to the pedestal 41 and the bottom. 8A or 9A is evacuated and the air resistance is reduced, so that the bottom 8A or the bottom 9A can be smoothly grounded by the suspension wire 21 fed from a winch (not shown). Has been made.

As shown in FIG. 11, a guide pipe 8 is installed on the inner surface of the guide box 5 along the vertical direction of the guide box 5, and the center coordinate position B of the light receiving sensor 23 of the laser beam detecting unit 22 is determined. It is arranged so as to be located directly above the center O of the opening 8B. Here, the laser light L1 emitted vertically upward from the bottom 8A of the guide pipe 8 is detected by the light receiving sensor 23, and XY from the position B of the laser light L1 emitted from the position C of the laser emission port 31B is detected. By measuring the displacement of the insertion tube on the coordinates with respect to the center line G3, the vertical of the guide box 5 can be measured. Furthermore, based on the measured displacement, the guide box 5 can be installed vertically using the jack 16. The four jacks 16 are arranged around the guide box 5 in correspondence with the XY coordinates of the light receiving sensor 23 above the guide pipe 8, and the displacement of the coordinates on the monitor 29 in the X-axis direction and the Y-axis direction The position of the guide box 5 can be adjusted according to ΔX and ΔY.

Further, as shown in FIG. 12, guide pipes 9 are installed at predetermined intervals L in parallel along the side surfaces of the vertical shaft 4. At this time, the horizontal movement direction and the horizontal movement distance (hereinafter referred to as the movement amount) of the center line G2 of the guide pipe 9 are the same as the movement amount of the center line G1 of the vertical shaft 4. The center O of the opening 9B of the guide pipe 9 is set vertically below the position B of the coordinate center on the light receiving sensor 23 of the laser beam detecting unit 22. In other words, when the straight pillar 4 is suspended vertically below the position A of the pillar support 2, the laser emission port 31 </ b> B of the laser device 20 installed at the bottom 9 </ b> A of the guide pipe 9.
Is located vertically below the position B.

Here, in the guide pipe 9 installed on the side surface of the vertical shaft 4, the center line G 1 of the vertical shaft 4 suspended from the excavation hole 2 A of the vertical support 2 on which the laser beam detector 22 is installed. Assuming that the position A of the excavation hole 2A on the horizontal plane 2B is the origin coordinate ( ₀ , ₀ ) and the center coordinate (X ₀ , Y ₀ ) of the light receiving sensor 23 located on the column support 2 is position B, The horizontal distance L to position B is

(Equation 1) Is obtained by

The distance from the position B to the bottom 9A of the guide pipe 9 located vertically below is defined as d.
Assuming that the height from A to the laser emission port 31B is h, the distance d 'from position B to position C is

(Equation 2) Is represented by Here, when the position of the guide pipe 9 at a distance d ′ vertically downward from the position A on the center line G1 of the vertical shaft 4 is defined as a position D, the horizontal distance from the position C to the position D is L. As described above, the fixing members 10 and 11 are used to install the truss pillar 4. As a result, the laser beam L1 emitted vertically upward from the laser emission port 31B provided in the vertical guide pipe 9 is applied to the position B on the light receiving sensor 23. That is, the displacements ΔX and ΔY in the X-axis direction and the Y-axis direction on the XY coordinate at the position D are XY at the position C.
The displacements ΔX and ΔY in the X-axis direction and the Y-axis direction on the coordinate coincide with the X-axis direction and the Y on the XY coordinate at the position B.
It becomes equal to the displacements ΔX and ΔY in the axial direction, whereby the displacements ΔX and Δ on the XY coordinate of the position D on the light receiving sensor 23 are obtained.
Y is detected as displacements ΔX and ΔY on the XY coordinate at the position B.

Here, the inclination Δa of the vertical shaft 4 is determined by the position D (X
_10, the displacement ΔX in X-Y coordinates in the Y _10), the following equation movement amount [Delta] L _D from ΔY horizontal direction H

(Equation 3) From the movement amount ΔL _D and d ′,

(Equation 4) Is obtained by Here, d ′ is sufficiently long and the movement amount ΔL _D is sufficiently small, so that the distance from the position A to the position D and the distance from the position A to the position where the movement amount ΔL _D is added to the position D are approximately equal. Consider the same.

In the above configuration, the laser device 20 is inserted into the guide pipe 8 provided on the inner surface of the guide box 5, and the vertical displacements .DELTA.X and .DELTA.Y of the guide box 5 detected by the laser beam detector 22 are measured. Jack 16
When the guide box 5 is vertically installed in the pile hole EH, the straight box 4 is guided by the guide box 5 and is built in the pile hole EH. A guide pipe 9 is fixed to the straight pillar 4 suspended from the pillar receiving base 2 along the outer peripheral side surface of the straight pillar 4, and the center position O of the opening 9 B of the guide pipe 9 is determined by the light receiving sensor. 23
The position of the light receiving sensor 23 is set so as to be located vertically below the center coordinate position B.

When the guide pipe 9 is fixed, the column support 2
The laser device 20 placed on the insertion jig 40 is suspended by the suspension wire 21 to the bottom 9A of the guide pipe 9. From the suspended laser device 20, visible laser light L1 is emitted vertically upward from the laser emission port 31B, and this visible laser light L1 is received by the light receiving sensor 23 installed on the column support 2. You.

At this time, as shown in FIG. 13, when the vertical shaft 4 is built with an inclination Δa with respect to the vertical direction, the vertical shaft 4 is vertically lowered from the hanging position A on the center line G1 of the vertical shaft 4. The position D at the predetermined distance d 'causes displacements of ΔX and ΔY in the X-axis direction and the Y-axis direction in the XY coordinates.
As a result, the shaft 4 is moved from the position D to the position D ′ in the horizontal direction H.
Causes a shift of the moving amount ΔL _D. At this time, the position C of the laser emission port 31B of the laser device 20 installed in the guide pipe 9 moves to the position C 'according to the inclination of the straight pillar 4. Here, X− from position C to position C ′
Movement amount [Delta] L _C of displacement ΔX and ΔY in the horizontal direction H with it in the X-axis direction and the Y-axis direction in the Y coordinate each equivalent of to the amount of movement [Delta] L _D and the displacement ΔX and ΔY to the position D'from position D Displacement and movement amount.

As a result, when the vertical shaft 4 is vertically built, the visible laser beam L1 received at the position B on the light receiving sensor 23 has the same displacement as that from the horizontal position C to the position C '. Light is received at a position B ′ shifted by ΔX and ΔY. Accordingly, if the guide box 5 is moved so as to cancel the detected displacements ΔX and ΔY using the respective jacks 16 installed along the axial direction of the XY coordinates around the guide box 5, a straight pillar can be obtained. 4 can be adjusted vertically.

The position B on the light receiving sensor 23 at this time is
′ Is coordinates (X ₁₀ , Y ₁₀ ), the amount of movement ΔL _B from position B to position B ′ is

(Equation 5) And the following equation

(Equation 6) Thus, the horizontal movement amount ΔL _{D of the} straight pillar 4 can be obtained. Furthermore,

(Equation 7) Thus, the inclination Δa of the straight pillar 4 can be obtained.

The irradiation position of the visible laser beam L1 detected on the light receiving sensor 23 is set on the XY coordinates of the monitor 29 of the personal computer 25 on the XY coordinates (X ₀ , Y
₀ ) together with the position D ′ and the displacement Δ from the position D to the position D ′
The numerical values of X and ΔY are displayed. Accordingly, the displacements ΔX and ΔY of the vertical shaft 4 equivalent to the inclination of the guide pipe 9 are immediately detected, and the vertical installation of the vertical shaft 4 can be easily adjusted based on the displacements ΔX and ΔY. . Further, the inclination Δa of the straight pillar 4 can be immediately calculated by the personal computer 25.

According to the above configuration, the laser light L1 emitted vertically upward from the bottom 9A of the guide pipe 9 installed in parallel along the side surface of the vertical shaft 4 is received by the light receiving sensor 23. The guide pipe 9
Can be immediately detected as displacements ΔX and ΔY in the XY coordinates. On this occasion,
In particular, even when the position where the vertical direction is measured is deep in the foundation pile hole, the worker can go down to the foundation pile hole and measure the deviation of the vertical shaft 4 in the horizontal direction H, and can save the worker's safety. Can improve. Further, the measurement result is immediately sent to the personal computer 25, the displacements ΔX and ΔY are displayed on the monitor 29, and the inclination is calculated, so that the time required for vertical measurement and adjustment can be greatly reduced.

In the above-described embodiment, the case where the guide pipe 9 is installed on the side of the straight pillar and then the laser device 20 is hung on the bottom of the guide pipe has been described. However, the present invention is not limited to this. Instead, the guide pipe may be installed on the side surface of the straight pillar to be measured in a state where the laser device 20 is arranged at the bottom of the guide pipe from the beginning.

Further, in the above-described embodiment, the case where the guide pipe for guiding the laser device 20 to the lower part of the vertical shaft 4 is of a single-stage type has been described, but the present invention is not limited to this, and the present invention is not limited thereto. It may be a two-stage type in accordance with the length of the object. That is, as shown in FIG. 14, the cylindrical guide pipe 44 is formed by joining two-stage pipes 44A and 44B. The joint 45 of the guide pipe 44 has a flange shape, and a packing 46 for stopping water is inserted into a connection portion between the flanges, and is joined by a bolt 47. With such a two-stage structure, the guide pipe 44 can be adjusted to a desired length corresponding to the length of the straight pillar 4.

Further, several skirts 48 made of a triangular plate-like steel material are provided above the flange of the joint 45.
