Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a buried auxiliary positioning device for tunnel monitoring and measuring points. Background Art

[0002] Tunnel monitoring and measurement is an indispensable part of the tunnel construction process. It involves monitoring and analyzing the entire process of tunnel construction, mastering the dynamic information of surrounding rock and support structure, and timely feedback of this information to provide a basis for adjusting design and construction. Through real-time monitoring, potential instability can be discovered early, thereby improving construction safety and preventing accidents such as landslides.

[0003] Tunnel monitoring and measurement is a must-measure item in the tunnel, usually including parameters such as arch settlement and peripheral displacement. Non-contact measurement is widely used in tunnel monitoring and measurement as an efficient, accurate and safe modern measurement technology. Non-contact measurement requires the arrangement and burial of monitoring points. Peripheral displacement measurement points are usually arranged in one or more horizontal measuring lines. The measurement points of the same section are generally arranged symmetrically, and the measurement points of different sections should be arranged in the same position; the arch settlement measurement points are usually arranged in 2 to 3 points in the arch area, and are generally arranged in the arch and left and right arch waist areas in the same section.

[0004] However, the current layout and positioning of monitoring points are usually carried out with the assistance of visual inspection, measurement and other means. The operation is extremely irregular and cannot meet the relevant requirements for the location of the measuring points. Utility Model Content

[0028] The base 10 is the basic platform of the entire auxiliary positioning device, and the base 10 can be a horizontally arranged plate. Of course, in the specific implementation, the structure and shape of the base 10 can be adjusted according to the needs, such as being designed as a frame or a support, etc., as long as it can carry other components.

[0029] The vertical indexing disk 20 is mounted on the base 10, and the vertical indexing disk 20 is perpendicular to the base 10. In one embodiment, the vertical indexing disk 20 is in an arcuate shape, and the vertical indexing disk 20 is connected to the base 10 through a triangular connecting portion 22. A scale for measuring angles is provided on the vertical indexing disk 20, and the scale is used to locate the position of the vertical laser emitter 40 on the vertical indexing disk 20. In one embodiment, the top end of the vertical indexing disk 20 is 90 degrees, and the bottom end of the vertical indexing disk 20 can be 0 degrees, or can be designed to be negative 20 degrees, etc., and the range of angle measurement can be specifically adjusted according to needs.

[0030] The horizontal laser emitter 30 is mounted on the base 10, and the horizontal laser emitter 30 can rotate up and down, and the plane where the horizontal laser emitter 30 rotates is perpendicular to the vertical indexing plate 20. The horizontal laser emitter 30 can rotate up and down, which can be easily aligned with the midpoint position of the tunnel road surface, so that the vertical indexing plate 20 is at the centerline position of the tunnel.

[0031] In one embodiment, the vertical laser emitter 40 is mounted on the vertical indexing disk 20 via a rotating connector 42, and a plurality of vertical laser emitters 40 are respectively mounted via a plurality of rotating connectors 42. One end of the rotating connector 42 is hinged on the vertical indexing disk 20, and the vertical laser emitter 40 is mounted on the other end of the rotating connector 42.

In this embodiment, the number of vertical laser emitters 40 and rotating connectors 42 is three, corresponding to two horizontal measurement points and one dome sinking measurement point respectively. It can be understood that in other embodiments, the number of vertical laser emitters 40 can be specifically set as needed, and the number of rotating connectors 42 corresponds to the number of vertical laser emitters 40.

[0033] In one embodiment, the tunnel monitoring measurement point buried auxiliary positioning device also includes a tripod 50, and the base 10 is carried on the tripod 50, so that the base 10 is in a horizontal state in an uneven tunnel environment. Further, the tripod includes two retractable legs 54 and a fixed leg 52, and the upper device of the tripod can be quickly adjusted to a horizontal state by retracting the two retractable legs 54.

The circular level bubble 56 can indicate whether the upper device of the tripod is in a horizontal state to ensure the accuracy of the laser line.

[0035] The working principle of the buried auxiliary positioning device for the above-mentioned tunnel monitoring and measuring point is specifically as follows:

[0036] (1) Use a total station or other equipment to stake out and mark the center point A at the tunnel section pavement location where the monitoring and measurement points are pre-buried, and mark another pavement center point B at intervals of about 5 to 10 meters on the staked section;

[0037] (2) Place the tripod fixed leg 52 on the center point A;

[0038] (3) Install the base 10 of the device on a tripod and secure it;

[0039] (4) Adjust the circular level bubble 56 so that the bubble is centered, and adjust the upper device of the tripod 50 to a horizontal state to ensure that the vertical indexing plate 20 is perpendicular to the tunnel axis;

[0040] (5) Adjust the horizontal laser transmitter 30 so that the laser spot falls on the center point B of the road surface and the vertical indexing plate 20 is located at the center line of the tunnel;

[0041] (6) Turn on the vertical laser transmitter, adjust the laser transmitter angle to locate the monitoring measurement point and mark it;

[0042] (7) Bury monitoring measurement points at the marked locations.
