Description

Technical Field

[0001] The utility model relates to the field of tunnel chamber deformation monitoring, in particular to a highway tunnel engineering quality deformation monitoring device. Background Art

[0002] After the tunnel chamber is excavated, it may become loose due to blasting vibration or mechanical force, or the release of original stress may cause deformation of the tunnel wall. It is necessary to monitor the deformation of the tunnel wall. In some monitoring methods, a typical observation section is selected in the cavern, and a verticality measuring instrument is used to continuously monitor the verticality of the section to determine the deformation value of the surrounding rock.

[0003] Analysis shows that the existing tunnel cavern monitoring methods have the following problems: Since the verticality measuring instrument is an instrument that uses the principle of air flotation to achieve precise guidance, the monitoring cost is high, it is inconvenient for manual observation during monitoring, and it is not suitable for tunnel cavern monitoring, and therefore inconvenient to operate.

[0004] Based on the above situation, there is an urgent need for a tunnel chamber deformation monitoring device to solve the problem of inconvenient monitoring operation. Utility Model Content

[0005] The purpose of the utility model is to use a verticality measuring instrument to continuously monitor the verticality of the cross section in the existing monitoring method to determine the deformation value of the surrounding rock. Since the verticality measuring instrument is a precision instrument that uses the air flotation principle to achieve precise guidance, the monitoring cost is relatively high and it is inconvenient for manual reflection observation during monitoring. The application provides a highway tunnel engineering quality deformation monitoring device to solve the problem of inconvenient monitoring operation.

[0006] The technical solution of the utility model is as follows:

[0007] A highway tunnel engineering quality deformation monitoring device, comprising:

[0008] A laser emitting end, used for emitting laser along a specified angle;

[0009] A movable block is attached to the monitoring surface and cooperates with the laser emitting end;

[0010] A reflector, mounted on the movable block and used to reflect the laser;

[0011] The receiving end cooperates with the laser emitting end and is used to receive the laser.

[0012] In the existing monitoring method, a verticality measuring instrument is used to continuously monitor the verticality of the section to determine the deformation value of the surrounding rock. Since the verticality measuring instrument is a precision instrument that uses the air flotation principle to achieve precise guidance, monitoring is inconvenient to operate. In this solution, a vertical observation section is selected in the tunnel chamber as the monitoring surface, the movable block is fitted with the detection surface, and the laser emitting end emits a laser at a specified angle to the reflector on the movable block. When the monitoring surface is deformed, the movable block will be driven to deflect, thereby causing the laser reflection angle emission to change. The receiving end can detect the reflection point of the laser to determine the deformation value of the monitoring surface. Compared with the use of a verticality measuring instrument in the traditional solution, the present application provides a solution with a simple structure, reduces the monitoring cost, facilitates manual observation of reflections during monitoring, and solves the problem of inconvenient monitoring operation.

[0013] Furthermore, in order to make the movable block fit the monitoring surface, one feasible solution is: the movable block is connected with an elastic member. When this solution is adopted, the movable block is pushed toward the monitoring surface by the elastic member so that the movable block is pressed against and fits the monitoring surface.

[0014] Furthermore, in order to enable the laser emitting end to emit laser along a specified angle, one feasible solution is: the laser emitting end is connected to an adjustment component for adjusting the laser emission angle. When this solution is adopted, the laser emitting end is adjusted by the adjustment component so that the laser emitting end emits laser along the specified angle.

[0015] Furthermore, the present solution does not limit the specific structure of the adjustment component. One feasible solution is: the adjustment component includes a threaded rod, and the laser emitting end is provided with a bevel gear that cooperates with the threaded rod. When this solution is adopted, the threaded rod is rotated to drive the bevel gear to rotate, thereby adjusting the laser emission angle of the laser emitting end.

[0016] Furthermore, in order to make the laser emitting end emit laser in a horizontal direction, one feasible solution is: a spirit level is installed on the laser emitting end. When this solution is adopted, the threaded rod is adjusted with the assistance of the spirit level to facilitate adjusting the laser emitting end to emit laser in a horizontal direction.

[0017] Furthermore, in order to facilitate fixing the movable block at a specified height, one feasible solution is: the laser emitting end is connected with a lifting part, the lifting part is penetrated by a vertical pole and a locking knob is installed on the lifting part. When this solution is adopted, the height of the movable block is adjusted by adjusting the height of the lifting part along the axis direction of the vertical pole, and the height of the movable block is fixed by tightening the locking knob.

[0018] Compared with the existing technology, the beneficial effects of the utility model are:

[0019] 1. A vertical observation section is selected in the cave as the monitoring surface, and the movable block is fitted with the monitoring surface. The laser emitting end emits laser at a specified angle to the reflector on the movable block. When the monitoring surface is deformed, the movable block will be driven to deflect, thereby changing the laser reflection angle. The receiving end can detect the reflection point of the laser to determine whether the monitoring surface is deformed. Compared with the verticality measuring instrument used in the traditional solution, the structure is simple, the monitoring cost is reduced, and the manual observation of reflection during monitoring is convenient, which solves the problem of inconvenient monitoring operation.

[0020] Second, since the movable block is connected with an elastic member, the movable block is pushed toward the monitoring surface by the elastic member, so that the movable block is pressed against and fits the monitoring surface;

[0021] 3. Since the adjustment component includes a threaded rod, a bevel gear that cooperates with the threaded rod is provided on the laser emitting end, and a level is installed on the laser emitting end, the threaded rod is adjusted with the assistance of the level to drive the bevel gear to rotate, and then the laser emitting end is adjusted to emit laser in the horizontal direction.

[0034] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0035] Example:

[0036] Please refer to Figure 2 and Figure 3 , a highway tunnel engineering quality deformation monitoring device, comprising:

[0037] A laser emitting end 1, used for emitting laser light at a specified angle;

[0038] The movable block 2 is attached to the monitoring surface and cooperates with the laser emitting end 1;

[0039] A reflector 3, mounted on the movable block 2 and used for reflecting laser light;

[0040] The receiving end 4 cooperates with the laser emitting end 1 and is used to receive laser light.

[0041] In the existing monitoring method, a verticality measuring instrument is used to continuously monitor the verticality of the tunnel section to determine the deformation value of the inner wall. Since the verticality measuring instrument is a precision instrument that uses the air flotation principle to achieve precise guidance, the monitoring cost is high and it is not convenient to operate. In this scheme, a new monitoring device is provided. A vertical observation section is selected in the cave as the monitoring surface. The movable block 2 of the monitoring device is fitted with the monitoring surface. The laser emitting end 1 emits a laser to the reflector 3 on the movable block 2 along a specified angle. When the monitoring surface is deformed, the movable block 2 will be driven to deflect, thereby causing the laser reflection angle emission to change. The receiving end 4 can detect the reflection point of the laser and determine whether the monitoring surface is deformed through the reflection point. Compared with the traditional method using a verticality measuring instrument, it is easier to operate. The operator can observe the monitoring results through the reflection point at the receiving end 4. The monitoring cost is low, which solves the problem of inconvenient monitoring operation.

[0042] Reference Figure 3 and Figure 4In order to make the movable block 2 fit the monitoring surface, one feasible solution is: the movable block 2 is connected with an elastic member 21. When this solution is adopted, the movable block 2 is pushed toward the monitoring surface by the elastic member 21 so that the movable block 2 is pressed against and fits the monitoring surface.

[0043] Reference Figure 2 In order to enable the laser emitting end 1 to emit laser along a specified angle, one feasible solution is: the laser emitting end 1 is connected to an adjustment component 5 for adjusting the laser emitting angle. When this solution is adopted, the laser emitting end 1 is adjusted by the adjustment component 5 so that the laser emitting end 1 emits laser along the specified angle.

[0044] Reference Figure 5 This solution does not limit the specific structure of the adjustment component 5. One feasible solution is: the adjustment component 5 includes a threaded rod 51, and the laser emitting end 1 is provided with a bevel gear 52 that cooperates with the threaded rod 51. When this solution is adopted, the threaded rod 51 is rotated to drive the bevel gear 52 to rotate, thereby adjusting the laser emission angle of the laser emitting end 1.

[0045] Reference Figure 3 and Figure 5 In order to make the laser emitting end 1 emit laser in the horizontal direction, one feasible solution is: a level 11 is installed on the laser emitting end 1. When this solution is adopted, the threaded rod 51 is adjusted with the assistance of the level 11 to facilitate adjusting the laser emitting end 1 to emit laser in the horizontal direction.

[0046] Reference Figure 1 In order to facilitate fixing the movable block 2 at a specified height, one feasible solution is: the laser emitting end 1 is connected to a lifting part 6, the lifting part 6 is penetrated by a vertical rod 61 and a locking knob 62 is installed on the lifting part 6, and the vertical rod 61 is arranged on the bottom plate 7. When this solution is adopted, the height of the movable block 2 is adjusted by adjusting the height of the lifting part 6 along the axial direction of the vertical rod 61, and the height of the movable block 2 is fixed by tightening the locking knob 62.

[0047] The working principle of this embodiment:

[0048] A vertical observation section is selected in the tunnel chamber as the monitoring surface, the movable block 2 is fitted to the monitoring surface, and the threaded rod 51 is adjusted with the assistance of the level 11 to drive the bevel gear 52 to rotate, and then the laser emitting end 1 is adjusted to emit laser in the horizontal direction. The reflection point of the laser can be detected by the receiving end 4 to determine whether the monitoring surface is deformed.

[0049] To solve the problems of high monitoring cost and inconvenient operation, in this solution, a vertical observation section is selected in the cave as the monitoring surface, the movable block 2 is fitted with the monitoring surface, and the laser emitting end 1 emits laser along a specified angle to the reflector 3 on the movable block 2. When the monitoring surface is deformed, the movable block 2 will be driven to deflect, thereby causing the laser reflection angle emission to change. The reflection point of the laser can be detected by the receiving end 4 to determine the deformation value of the monitoring surface. Compared with the traditional solution using a verticality measuring instrument, the present application provides a solution with a simple structure, which reduces the monitoring cost while solving the problem of inconvenient monitoring operation.

[0050] In order to make the movable block 2 press against and fit the monitoring surface, in this solution, since the movable block 2 is connected to the monitoring surface by an elastic member 21, the movable block 2 is pushed toward the monitoring surface by the elastic member 21 so that the movable block 2 presses against and fits the monitoring surface.

[0051] In order to enable the laser emitting end 1 to emit laser in a horizontal direction, in the present solution, since the adjustment component 5 includes a threaded rod 51, a bevel gear 52 cooperating with the threaded rod 51 is provided on the laser emitting end 1, and a level 11 is installed on the laser emitting end 1. The threaded rod 51 is adjusted with the assistance of the level 11 to drive the bevel gear 52 to rotate, thereby adjusting the laser emitting end 1 to emit laser in a horizontal direction.
