First, if a steel wire with a weight is dropped into a vertical shaft, the weight hanging from the end of the steel wire will continue to shake underground without stopping due to the Earth's rotation and magnetic force. As the shaking subsides, it becomes a state where the shaking remains constant. Accordingly, the worker who went down to the bottom area of the vertical shaft measures the X-axis and Y-axis shaking of the weight with a measuring instrument to set a horizontal reference point.

And when the measurement of the horizontal reference point is completed in this way, the plate marked with the cross-shaped origin is placed on the bottom of the weight, and the center of the plate is matched with the set horizontal reference point using a measuring instrument again, and then the operator hammers and nails or Using a tableting gun, hit the fixing means against the ground at the center of the plate to fix it.

And after fixing the plate marked with the cross-shaped marker in this way, another horizontal reference point is set by installing one more plate on the horizontal centerline spaced apart from the fixed plate by a certain distance using a measuring instrument.

The present applicant has proposed the present invention as a technology that allows the vertical transfer of horizontal reference points in vertical shafts or buildings to be performed more accurately in addition to improving the workability of the steel wire method described above.

A plurality of solenoid actuators 160 installed on the upper surface of the transparent shelf 140 to be positioned below the weight immersion tank 150 to provide lifting power to the weight immersion tank 150;
a laser distance meter 170 installed on the top surface of the top plate 111 and measuring the distance between the panel structure 20 and the top plate 111;
A first user operation switch 181 installed on the upper surface of the top plate 111 as a user's operation purpose for the electronic locking device 130;
A second user operation switch 182 installed on the upper surface of the top plate 111 for the user's manipulation of the laser pointer 123;
a short-distance wireless communication module 191 for wirelessly transmitting the control signal to the short-distance wireless communication module 124 of the weight 120 according to an ON operation of the second user operation switch 182;
Based on the distance between the panel structure 20 and the top plate 111, the solenoid actuator 160 rises with respect to the weight immersion tank 150 from the time when the unlocking operation of the electronic locking device 130 is performed a storage unit 192 for pre-setting and storing immersion tank operation standby times corresponding to the elapsed time until operation starts; and
Installed on the table 110 and detecting the corresponding flooding tank operation waiting time among the flooding tank operating standby times of the storage unit 192 according to the distance measurement signal transmitted from the laser distance meter 170, and then the detected flooding Horizontal reference point vertical displacement surveying device using a laser plumb machine and a steel wire method including a control unit 193 for controlling the operation of the solenoid actuator 160 according to the jaw operation waiting time.
