Because the basic measurement control network of a work area is determined, the erection position of the instrument is relatively fixed, the gate slot embedded parts are generally divided into a main rail, a side rail and a reverse rail, the measurement instrument is erected in one position and cannot completely measure three-side rails, the measurement of all embedded parts can be carried out only by moving the instrument twice, the preparation time of personnel and equipment is consumed in the process of moving the instrument and is influenced by the concrete body type, the erection position of the instrument is limited, and the measurement precision is reduced due to the fact that a prism cannot be erected, so that a novel measurement device is required to be used for measurement.
The existing measurement conditions are fully utilized, the rolled concrete arch dam pouring partition layering is combined, and the control of the installation accuracy of embedded parts is the key for ensuring the smooth operation of a later-stage gate. In view of the above, it is necessary to use the existing measurement conditions to match with the corresponding detection devices.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some examples of the present invention, not all examples. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, the gate slot embedded part position measuring device of the concrete arch dam gate 4 of the embodiment includes a steel wire rope 5 arranged between the back sides of the working surfaces 2.1 of the embedded parts 2 to be measured on the two sides, at least one reflective lens 6 is sequentially arranged on the rope, the total station is arranged in front of the embedded parts 2 to be measured on the two sides, a blind zone 3 is arranged for the measuring instrument in the area between the concrete arch dam gate 4 and the embedded parts 2 to be measured on the two sides, and the gate slot flatness and the blind spot in the measuring area are judged through the position data of the reflective lens measured by the total station emitting laser 7. Two ends of the steel wire rope 5 are tightly attached to the measuring working surface. The position of the mirror plate 6 corresponds to the position size of the insert 2 to be measured, as shown in fig. 2. The diameter of the steel wire rope 5 is 1.2 mm.
In this embodiment, the total station 1 cannot be arranged in the measurement arrangement blind area in the drawing due to the influence of the site terrain and the building, and the laser beam cannot measure the working surface of the embedded part frontally.
The total station 1 is arranged on the reverse side of the working surface of the embedded part to be measured, and cannot directly measure the precision data such as the flatness, the verticality and the like of the working surface of the embedded part to be measured. The reflecting sheet is fixed on the steel wire rope, the mounting accuracy of the embedded part is reflected on the reflecting sheet, and meanwhile, the measuring instrument controls the mounting accuracy of the embedded part according to the measured position data of the reflecting sheet.
Wherein, the door slot roughness measurement principle is as follows:
and arranging a steel wire rope at any position of the two door slots, arranging at least two light reflecting sheets on the steel wire rope, and emitting laser again by the total station to measure the coordinates of the two light reflecting sheets. And then changing an arbitrary elevation, arranging a steel wire rope, emitting laser again by the total station, and measuring the coordinates of the two reflectors. And (4) calculating whether the coordinates of the four points are coplanar, wherein if the coordinates of the four points are coplanar, the flatness of the door slot is better. In order to improve the measurement accuracy, a plurality of groups of steel wire ropes are usually measured, and a plurality of groups of reflective sheets are usually measured on each steel wire rope.
The measurement process of the measurement zone blind spot in this embodiment is as follows:
as shown in fig. 3, by arranging a steel wire at a blind spot to be measured (a position where a door slot cannot be directly measured), the total station can measure 2 reflectors arranged on the steel wire at any position of an area, and by measuring point coordinates of the 2 reflectors, a steel wire distance between the blind spot to be measured and the reflectors, the coordinates of the blind spot to be measured are calculated on a linear equation. The wire distance can be measured directly by a precision ruler.
Two-point coordinates of the measured light reflecting sheet are respectively A (X)1，Y1，Z1）,B（X2，Y2，Z2). Setting P coordinate of blind spot to be measuredIs (X, Y, Z)
By calculating the distance L between the steel wires AB1Measuring the distance L between the wires of PA2，
Then L1/(X1-X2) = L2/(X-X1)
Thereby obtaining the X coordinate of the point P to be measured
And the Y coordinate and the Z coordinate of the point to be measured can be obtained in the same way.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
