Description

Technical Field

[0001] The utility model relates to the technical field of laser reflection marks, in particular to a reflection mark device used for total station to measure tunnel structure. Background Art

[0002] With the rapid development of my country's economy, urban underground engineering construction is restricted by surface structures, and underground tunnel projects are increasingly using shield construction methods. After shield construction, pipe segments need to be assembled for support to ensure that the tunnel section has standard firmness and stability.

[0003] The monitoring of the vertical and horizontal displacement of the tunnel segments is an important monitoring item during shield construction. The change in the clearance size inside the tunnel is called convergence displacement. The tunnel clearance convergence measurement is widely used as a method to judge the stability of the tunnel support structure. At present, the tunnel clearance convergence monitoring during the construction process mainly adopts the installation of laser emission markers in the tunnel, and then the laser emission markers are checked by the total station, and then the tunnel clearance convergence monitoring is carried out. In the existing project, in order to install the laser reflection marker on the tunnel surface, the laser reflection marker is set on the angle steel, and then the laser reflection marker is set on the tunnel surface through the angle steel. Although the laser reflection marker can be stably set on the tunnel surface by the above method, the angle steel generally has an "L" structure, which makes the laser reflection marker set perpendicular to the tunnel surface. Therefore, in order to clearly observe the laser reflection marker, the detection personnel need to move the total station to a farther position, which greatly increases the detection difficulty of the detection personnel. Therefore, a new type of laser emission marker device is urgently needed to enable the detection personnel to detect the laser reflection marker more conveniently. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The utility model is a reflective marker device used for measuring tunnel structures with a total station. Figure 1-2 , including: a base 1, a first connecting arm 2, a mounting seat 3 and a reflective mark 4, wherein the base 1 is used to be fixed on the tunnel surface; a fixing piece 5 is provided on the base 1, and the first end of the first connecting arm 2 is hingedly set on the fixing piece 5; the mounting seat 3 is set at the second end of the first connecting arm 2 and is hinged with the first connecting arm 2; the reflective mark 4 is set on the mounting seat 3, and the reflective mark 4 moves with the mounting seat 3. During use, the reflective mark 4 is fixed on the tunnel surface through the base 1, and then the position and orientation angle of the reflective mark 4 are adjusted through the first connecting arm 2 and the mounting seat 3, so that the detection personnel can observe the reflective mark 4 more easily, thereby greatly reducing the detection difficulty of the detection personnel.

[0027] In this embodiment, the fixing member 5 is rotatably connected to the base 1. The rotatably connected fixing member 5 and the base 1 enable the fixing member 5 to drive the first connecting arm 2 and the mounting seat 3 to rotate during the rotation process, thereby adjusting the direction of the reflective mark 4, thereby increasing the flexibility of the reflective mark 4 device when in use.

[0028] Specifically, in this embodiment, the fixing member 5 includes a rotating shaft 6 and a rotatable member 7. The first end of the first connecting arm 2 is arranged on the rotatable member 7. The rotatable member 7 is rotatably arranged on the base 1 through the rotating shaft 6, so that the rotatable member 7 is rotated through the rotating shaft 6. Secondly, a damper is also provided at the connection part between the rotating shaft 6 and the rotatable member 7. The damping member enables the rotatable member 7 to be fixed at any position, which greatly reduces the installation difficulty of the detection personnel when installing the reflective mark 4 device.

[0029] In this embodiment, ears 8 are provided at both ends of the first connecting arm 2, and connecting shafts 9 compatible with the ears 8 are provided on the rotating member 7 and the mounting seat 3. The rotating member 7 and the mounting seat 3 are rotatably connected with the ears 8 through the connecting shaft 9, and a damper is also provided at the connecting portion between the connecting shaft 9 and the ears 8. The damper enables the inspector to more easily adjust the angle between the first connecting portion and the rotating member 7 or the mounting seat 3.

[0030] In the present embodiment, the ear piece 8 includes a first ear piece 10 and a second ear piece 11, and the first ear piece 10 and the second ear piece 11 are arranged at the ends of both ends of the first connecting arm 2, and the first ear piece 10 and the second ear piece 11 are arranged at intervals to form a rotation groove, and the connecting shaft 9 is in a "T" shape. The connecting shaft 9 is placed in the rotation groove, and the two ends of the connecting shaft 9 are respectively connected to the first ear piece 10 and the second ear piece 11. In the present embodiment, since the first ear piece 10 and the second ear piece 11 are placed at the ends of the first connecting arm 2, and the connecting shaft 9 is in a "T" shape, the mounting seat 3 and the base 1 can be flipped at a larger angle during use.

[0031] In this embodiment, the base 1 is further provided with a mounting hole 12 for screws to pass through, and the mounting hole 12 enables the reflective marker 4 device to be more easily installed on the tunnel surface.

[0032] In this embodiment, adhesive is also provided on the base 1. During use, the base 1 is attached to the tunnel surface by the adhesive, which further reduces the construction difficulty of installing the reflective marker 4 device on the tunnel surface.
