[0002] When measuring in underground projects such as underground mines, most of the measuring points are on the roof. During the measurement, it is necessary to perform point-to-point centering operations. It is necessary to use a ladder to hang hammer balls or hang prisms, which is inconvenient and dangerous; , the hammer ball and the prism are constantly swinging, it is impossible to realize the centering of the hammer ball or the distance measurement through the prism
If the measurement is carried out in the transportation roadway with power lines, this operation will also face the risk of electric shock. Therefore, it is inconvenient and dangerous to use the original instrument for engineering measurement underground or in the tunnel, which will affect the work efficiency and measurement efficiency of the measurement. precision

Embodiment Construction
[0016] Below in conjunction with the accompanying drawings, the operation method of pointing and centering using a total station or a target plate that generates a vertical laser beam will be described in detail.
[0017] When in use, place a special total station or target plate that can generate a beam of vertical laser light on the tripod, move the instrument below the position of the measuring point, level the circular level, turn on the laser, and the instrument can generate a beam that is consistent with the instrument. The vertical axes are coincident, and the laser beam near the measuring point on the top plate is irradiated vertically upwards. like figure 1 As shown, let the laser point be B and the measuring point be A. At this time, check whether the distance between the laser point B and the measuring point A formed by the laser beam on the top plate is > 6CM, if > 6CM, then move the instrument to the direction of A The moving distance of each tripod tip is equal ...

A centering under point operation method of a total station or target for generating a plumb laser beam is characterized by comprising the following steps of: supposing the point emitted by the plumb laser beam on a top board is B and a measuring point is A, determining whether the distance from the laser point B formed by the laser beam on the top board to the measuring point A is larger than 6CM, respectively moving each foot rest tip of the device in the direction of the A point until the moving distance equals to the length from A to B if the distance is larger than 6CM; leveling a circular bubble, determining whether the distance from the laser point B on the top board to the A point is larger than 6CM, moving the foot rest tip if the distance is still larger than 6CM, repeating the last operating step until the distance from the laser point B to the measuring point A on the top board is less than 6CM, stabilizing the foot rest, adjusting the screw of the foot to place the circular leveling bubble in the middle, and accurately centering and leveling the device by three methods of foot screw-foot rest method, foot rest-foot screw method and approaching method.
Description
technical field [0001] The invention belongs to an operation method for pointing and centering by using a total station or a target plate which generates a vertical laser beam in underground engineering survey. Background technique [0002] When measuring in underground projects such as underground mines, most of the measuring points are on the roof. During the measurement, it is necessary to perform point-to-point centering operations. It is necessary to use a ladder to hang hammer balls or hang prisms, which is inconvenient and dangerous; , The hammer ball and the prism are constantly swinging, so it is impossible to realize the centering of the hammer ball or the distance measurement through the prism. If the measurement is carried out in the transportation roadway with power lines, this operation will also face the risk of electric shock. Therefore, it is inconvenient and dangerous to use the original instrument for engineering measurement underground or in the tunnel, w...
