[0036] Working principle:

[0037] The first step: first use the connecting mechanism to connect the pendant 5 to one end of the bottom of the bracket 1, then use the pendant 5 to determine that the bracket 1 and the lifting hole are on the same vertical line, and determine the position of the bracket 1, and then use the adjustment mechanism to control one set of fixing plates 7 to move away from the other set of fixing plates 7, and then fit the bottom of the bracket 1 and the part located between the two sets of fixing plates 7 to the top of the concrete jacking pipe, and then use the adjustment mechanism to control the distance between the two sets of fixing plates 7 to be reduced, so that the bracket 1 can be fixed to the top of the concrete top.

[0038] Step 2: Arrange the two sets of fixing grooves 2 on the top of the bracket 1 symmetrically along the center line of the bracket 1, and the angle between the center lines of the two sets of fixing grooves 2 is 45°. Then place the two sets of optical side parts 3 into the inner walls of the two sets of fixing grooves 2 respectively, and then use the mounting holes 9, mounting rods 10 and connecting holes 11 to fix the protective shell 4 to the top of the bracket 1, so that the angle between the incident angles of the two sets of optical measuring parts 3 installed inside the two sets of fixing grooves 2 is 45°.

[0039] Step 3: Turn on the laser level and project it onto the inner wall of the concrete jacking pipe to mark the position of the light spot. Then place the grouting pipe to the vertical embedded depth of the marked point. Then, perform this method symmetrically once to locate the positions of the other two grouting pipes. This allows for precise positioning of the grouting pipes and allows the device to achieve precise positioning of a variety of embedded parts by adjusting the scale lines at different angles.
