  However, since extremely high accuracy is required for the installation of the base material, the adjustment work and the measurement for moving the base material with a bar or the like are repeated many times until it falls within the tolerance specified by the orderer. Although it is necessary, conventionally, there is no equipment that can easily measure the installation state, and there is no effective means for leveling variation in measurement accuracy due to a difference in the ability of the operator. In addition, although the base material may move during concrete placement, there was no simple measuring device that could confirm the displacement of the base material during work.

  Furthermore, in the configuration of Patent Document 2, only the rolling of the base material can be measured, and all installation dimensions cannot be measured. In the configuration of Patent Document 3, an obstacle is placed between the fixed points of the tower leg tops. It is possible to measure the installation even if there is, but it is necessary to arrange the light wave rangefinder in a position where the fixed point of the top of each leg can be seen, and such arrangement is physically If it was difficult, it could not be used.

The present invention has been made in view of the above circumstances, and can be easily measured regardless of the presence or absence of obstacles in the steel tower foundation work. The main problem is to provide a measurement method for steel tower foundation work that can be eliminated and that can easily check the displacement of the foundation material during work.

In order to achieve the above object, a measurement method for tower foundation work according to the present invention can be detachably attached to a foundation material of a tower structure installed in a drilling hole, and the tower center with respect to the vertical line of the foundation material Inclination angle detection unit for detecting data on a diagonal inclination amount indicating a tilt angle in a direction and a horizontal inclination amount indicating a horizontal inclination angle with respect to a steel tower center facing the base material , and transmission time data are included. An instrument for mounting a base material having a radio wave transmitter that transmits radio waves, and a data transmitter that transmits data related to the tilt angle detected by the tilt angle detector, and any other than that on the center line of the steel tower structure A radio wave receiving unit that is installed in three or more locations and receives radio waves transmitted from the radio wave transmitting unit; a position data acquiring unit that receives GPS signals and acquires its own position data; And a ground installation device having a data transmission unit for transmitting the transmission time data and the reception time data of the radio wave received by the radio wave reception means together with the position data, and data reception for receiving data transmitted from the data transmission unit Based on various data received by the data receiving unit, a data calculating unit for calculating fixed point position information of a member on which the base material mounting measuring instrument is installed, and the fixed point position information calculated by the data calculating unit. Comparing with a design value, a comparison result calculation unit for calculating a comparison result including correction information, and a measurement result display device having a display unit for displaying the comparison result calculated by the comparison result calculation unit. that a method using a steel tower foundation construction measuring device, measuring instrument attached to be attached to the upper end of the foundation member of the tower structure to be installed the basic material mounting instrument in wellbore Then, the data calculation unit calculates the position information of the base material top based on the data transmitted from the data transmission unit of the ground installation device, and the comparison result calculation unit calculates the position information of the base material top. The first step of calculating a comparison result including correction information on the installation position of the top of the base material compared to the above, and displaying the comparison result on the display unit, and the measuring instrument for mounting the base material on the data calculation unit The diagonal direction inclination amount and the horizontal direction inclination amount of the base material are calculated based on the data relating to the inclination angle transmitted from the data transmission unit, and the diagonal direction inclination amount and the horizontal direction inclination amount are calculated by the comparison result calculation unit. And a second step of calculating a comparison result including correction information of the diagonal direction tilt amount and the horizontal direction tilt amount and displaying the comparison result on the display unit. age ing.

Here, for the calculation of the fixed point position information of the member that installs the base material mounting measuring instrument, the transmission time data of the radio waves transmitted from the base material mounting measuring instrument, the reception time data of the radio waves received by the ground installation device, etc. Therefore, it is desirable that the base material mounting measuring instrument and the ground installation device have a time data acquisition unit that acquires time data by GPS and performs time synchronization.
Moreover, as a measuring instrument for mounting a base material, a mounting portion that is formed in accordance with the surface shape of the base material and is detachably mounted on the surface of the base material, and extends outward from this mounting portion, an inclination angle It is good to have the structure which comprises the measuring device main body with which the detection part and the electromagnetic wave transmission part were integrated.

Therefore, if such a measurement method is used, the measurement baseline is determined by the ground installation device installed on the center line of the tower and any other three or more locations, and the data calculation unit measures the foundation material attachment. The fixed point of the member that installs the measuring instrument for mounting the base material based on the transmission time data of the radio wave transmitted from the radio transmission unit of the instrument, the reception time data of the radio wave received by the reception unit of the ground installation device, and the position data of the ground installation device The position information is calculated, the fixed point position information calculated by the data calculation unit by the comparison result calculation unit is compared with the design value, the comparison result including the correction information is calculated, and the comparison calculated by the comparison result calculation unit by the display unit Since the result is displayed, the installation state can be easily measured, and variation in measurement accuracy due to the difference in the ability of the operator is eliminated.

  In addition, since it is possible to measure the installation dimensions using radio waves and GPS signals transmitted from the measuring instrument for mounting the base material, when there is an obstacle etc. and the fixed point at the top of each base material cannot be seen However, it is possible to reliably measure the installation dimensions.

Furthermore, the position of the top of the base material is designed by adjusting the installation position of the top of the base material so that it matches the design value within a predetermined tolerance while looking at the comparison result displayed on the display unit in the first step. It becomes possible to install according to the value.
  Further, in the second step, the diagonal inclination amount (rolling) and the horizontal inclination amount (dimension) of the base material are matched with the design value within a predetermined allowable range while observing the comparison result displayed on the display unit. By adjusting in this way, it becomes possible to make the fall and the behavior as designed.

In addition, it is useful to use the measurement method described above for adjusting the position of the upper end of the foundation material or for precise adjustment of the foundation material, but in the case of performing steel tower foundation work using the measurement device described above. First, it is necessary to measure the excavation position of the excavation hole, and then to adjust the installation position of the lower end portion of the base material attachment measuring instrument.

For this reason, in order to measure the excavation position of the excavation hole, the measuring instrument surface arrangement step of attaching the base material attachment measuring instrument to the temporary base material, determining the planned excavation site of the excavation hole, and arranging it on the ground surface, and the data Based on the data transmitted from the data transmission unit of the ground installation device in the calculation unit, the position information of the fixed point position of the lower end of the temporary base material is calculated, and the position information of the fixed point position of the lower end of the temporary base material is calculated in the comparison result calculation unit And a third step of calculating a comparison result including correction information of the installation location of the temporary base material by comparing with the design value of the excavation center and displaying the comparison result on the display unit. Also good.

  According to such a method, it becomes possible to measure the center of excavation using the foundation material mounting measuring instrument instead of the tape measure, and the fixed point position of the lower end of the temporary foundation material is within the predetermined allowable range with the design value of the excavation center. By excavating a point that matches, the drilling hole can be drilled at a point as designed.

Next, in order to adjust the installation position of the lower end portion of the base material mounting measuring instrument, the measuring instrument that is mounted on the temporary base material and placed on the mounting base placed at the bottom of the excavation hole The position information of the fixed point position of the lower end of the temporary base material is calculated based on the data transmitted from the data transmitting unit of the ground installation information in the gantry placement step, and the temporary calculation result calculation unit calculates the temporary base material. The position information of the fixed point position of the lower end is compared with the design value of the installation position of the lower part of the base material, the comparison result including the correction information of the installation location of the temporary base material is calculated, and this comparison result is displayed on the display unit. You may make it further comprise 4 processes.

  According to such a method, while observing the comparison result displayed on the display unit, the fixed point position of the lower end of the temporary base material is adjusted to match the design value of the installation position of the lower end of the base material within a predetermined allowable range. If it does so, it will become possible to specify the installation position of the lower end part of a base material as a design value.

As described above, according to the measurement method for tower foundation work according to the present invention, it is possible to easily measure all the installation dimensions of the excavation position and the foundation material of the tower structure even if there are obstacles between the foundation materials. In addition, it is possible to eliminate variations in measurement accuracy due to differences in worker ability.

If not within the allowable error, the position of the temporary base material 10 is adjusted based on the correction information, and the current position of the temporary base material 10 is re-evaluated (S524). . If the installed location matches the installation position of the lower part of the base material within a predetermined allowable error range, the lower end position (position indicated by β) of the current temporary base material 10 is set to the lower part of the base material. The installation position is determined, and the position is marked on the installation base 20 (S6).

  When the planned installation position of the lower part of the base material is determined, the base material 1 is suspended and placed on the mounting base 20 from above, the support material is attached to the base material 1, and the lower position of the base material 1 is aligned with the marking position.

The comparison result including the correction information (correction direction, correction amount, etc.) of the tilt amount and the presence or absence of the allowable error is calculated, and the comparison result is displayed on the display unit 4d (S824).

  If the current position of the base material top and the amount of inclination of the base material (foundation state of the base material) match within the specified tolerance range, the installation adjustment of the foundation material top ends and the current position of the foundation material top is within the tolerance range. If it is not within the range, or if the amount of inclination of the base material 1 is not within the allowable error range, the top position and the amount of inclination are adjusted based on the correction information using a bar or the like, and the installation state of the base material 1 is evaluated again.
