Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel construction tools, specifically relating to a device for controlling multi-level elevation lines during tunnel lining construction. Background Technology

[0002] To improve the construction quality of the tunnel invert lining, the geotextile, waterproofing membrane, upper and lower reinforcing bars, embedded waterstop, concrete pouring elevation, and longitudinal drainage pipes of the tunnel invert lining are constructed according to the design elevation with an error controlled within ±20mm. This involves numerous construction steps, making on-site control difficult. The traditional method uses a total station to lay out the elevations of the two ends of the invert lining. However, because multiple elevation lines need to be set for the multi-layered structure, multiple ink lines need to be drawn to control the elevation, making the drawing process cumbersome and prone to errors.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected" and "linked" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0024] like Figure 1-2 As shown, a device for controlling multi-level elevation lines during tunnel lining construction includes a base 1 and a support rod 5. The base 1 and the flip plate 2 are metal plates, both having flat upper and lower surfaces. The flip plate 2 is hinged to the top, and the length of the flip plate 2 is adapted to the length of the base 1. A limiting mechanism is provided between the end of the base 1 and the flip plate 2. The limiting mechanism can limit the flip angle of the flip plate 2, so that it maintains the set angle after flipping. This allows the flip plate 2 to switch between two states: flat and upright.

[0025] Multiple support rods 5 are detachably mounted on the upper surface of the flip plate 2. A laser collimator 6 is provided on the support rod 5 and slidably mounted along its length. The laser collimator 6 can emit a red laser line, so the number and spacing of the laser collimators 6 can be adjusted according to actual needs, thereby facilitating the height adjustment and control between the layers of the structure.

[0026] In this implementation, scales are provided on both the support rod 5 and the flip plate 2, so only the initial elevation control is required. Subsequently, the laser collimator 6 can be adjusted through the support rod 5, reducing the measurement steps and improving construction efficiency.

[0027] In an optional embodiment, a dovetail groove extending along its length is provided above the flip plate 2. The support rod 5 is slidably assembled in the dovetail groove via a slider 3. The cross section of the slider 3 is adapted to the dovetail groove to form a stable sliding relationship. A fixing bolt is provided on the slider 3. The fixing bolt passes through the slider 3 from top to bottom and abuts against the bottom surface of the dovetail groove to fix the support rod 5 and prevent the slider 3 from slipping during the flipping process.

[0028] In an optional embodiment, the base 1 is a metal plate with a flat upper surface. The lower surface of the flip plate 2 is provided with a magnetic component corresponding to the base 1, and the lower surface of the flip plate 2 is provided with an assembly groove corresponding to the magnetic component. The magnetic component is a magnet, which is embedded in the assembly groove to achieve assembly, so that the two can maintain relative stability through the attraction of the magnet.

[0029] In an optional embodiment, the limiting mechanism is a limiting strip 4 that protrudes upward and is located on the edge of the base 1. The limiting strip 4 and the base 1 are integrally formed. An inclined surface is provided on the side of the limiting strip 4 corresponding to the flip plate 2. The edge of the flip plate 2 is provided with a chamfered surface corresponding to the inclined surface. The chamfered surface is a flat surface. The two are adapted to each other. The flip plate 2 and the base 1 are hinged by a hinge. After the flip plate 2 is flipped, the inclined surface and the chamfered surface abut against each other to limit the angle of the flip plate 2. In this embodiment, it is preferable that the flip plate 2 is perpendicular to the base 1 after flipping. Therefore, the angle between the inclined surface and the chamfered surface is set to 45°. In this way, after flipping, the two are pressed against each other so that the flip plate 2 is perpendicular to the base 1. Furthermore, the flip plate 2 will be pressed against the limiting strip 4 from the left and right sides of the support rod 5 and the laser collimator 6. In addition, an assembly pin can be provided. The assembly pin passes through the inclined surface and the chamfered surface to ensure the stable relationship between the two.

[0030] In an optional embodiment, the laser collimator 6 is mounted on the support rod 5 via a sliding sleeve 8. The shape of the sliding sleeve 8 is adapted to the support rod 5, thereby slidably assembling the support rod 5. After the locking bolt 9 extends radially along the sliding sleeve 8, it abuts against the support rod 5, and the locking bolt 9 tightens the support rod 5 to lock the sliding sleeve 8.

[0031] Furthermore, in order to allow for the adjustment of the laser collimator 6 angle, a connecting rod 10 is provided on the side of the sliding sleeve 8 away from the locking bolt 9. The connecting rod 10 extends horizontally, and one end of the connecting rod 10 extends into the sliding sleeve 8 and connects to a limiting flange. The limiting flange is made of rubber, so that it is pressed tightly against the sleeve and the support rod 5 under the pressure of the locking bolt 9, and thus limited by friction. The other end of the connecting rod 10 is connected to the laser collimator 6 through a clamp 7. Generally, the laser collimator 6 is cylindrical, so the clamp 7 is set as a U-shaped structure with the opening facing upward, so as to facilitate the assembly and disassembly of the laser collimator 6.

[0032] Furthermore, the base 1 is provided with adjustable support feet. The adjustable support feet can be bolts threaded onto the base 1. The four adjustable support feet are located at the four corners of the base 1, thereby enabling adjustment and ensuring that the upper surface of the base 1 is in a horizontal state.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
