[0002] Tunnel construction environmental monitoring is a key link to ensure that the tunnel construction process is safe, efficient and environmentally friendly. It involves real-time and continuous monitoring of the construction site and its surrounding environment to prevent potential safety hazards, reduce the impact on the environment, and optimize the construction process. Through tunnel construction environmental monitoring, potential safety hazards can be discovered and dealt with in a timely manner, such as changes in geological structures and groundwater level fluctuations. At the same time, the impact of construction on the surrounding environment, such as noise, vibration, air pollution, etc., can be obtained to ensure that construction activities meet environmental protection requirements.

[0003] At present, there are several monitoring methods for environmental monitoring, such as sensor monitoring, drone monitoring and manual inspection. Sensor monitoring is usually used for highway tunnel construction monitoring. Environmental monitoring instruments are installed in highway tunnels for real-time monitoring. However, during tunnel construction, it is inevitable that gravel will fall, accompanied by groundwater seepage and dripping, which can easily cause damage to environmental monitoring instruments. Therefore, the present application proposes a highway tunnel construction environmental monitoring device. Utility Model Content

[0013] Beneficial Effects

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model uses a mounting arm arranged at the bottom end of the support column, and a positioning bolt simultaneously passes through the first positioning hole and one of the second positioning holes on the rotating connecting seat to relatively fix the mounting arm and the support column. The air quality environment monitor can be fixedly supported and installed by using the mounting arm and the support column. Moreover, since a plurality of second positioning holes are provided around the rotating axis of the mounting arm, the positioning bolt passes through the second positioning holes at different positions, so that the mounting arm and the support column can be relatively fixed at different angles. As a result, the air quality environment monitor can be supported and installed on the ground or tunnel wall at different inclination angles at the highway tunnel site, and the utility model has high flexibility and adaptability.

[0016] In the utility model, by setting the elastic telescopic arm and the protective cover, the elastic force support of the piston arm by the spring is utilized, so that the elastic telescopic arm as a whole elastically supports the protective cover, and the protective cover is endowed with elastic buffering performance, so that the top of the air quality environment monitor can be protected, and the falling gravel during the tunnel construction process can be prevented from damaging the air quality environment monitor. Moreover, since the elastic telescopic arm is directly mounted on the support column, the direct force on the air quality environment monitor when the gravel falls is avoided, and the protective effect on the top of the air quality environment monitor is further improved. In addition, the upper surface of the protective cover is arched in an arc shape, and the water guide box is arranged on both sides of the protective cover. The groundwater dripping during the tunnel construction process can be guided by the protective cover to the water guide box, and then the inclined surface of the bottom wall of the water guide box is used to guide the groundwater to the downpipe and drain from the back side of the air quality environment monitor. The convex edge arranged on the side of the protective cover facing the front of the air quality environment monitor can prevent the water dripping on the protective cover from dripping toward the front of the air quality environment monitor, thereby effectively preventing the groundwater leaking during the tunnel construction from affecting the air quality environment monitor, and having high protective performance.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] This embodiment provides a highway tunnel construction environment monitoring device, and its structural schematic diagram is as follows: Figure 1-Figure 5 As shown, it includes an air quality environment monitor 1; a support column 2 vertically arranged at the bottom of the air quality environment monitor 1; an elastic telescopic arm 3 arranged on the support column 2; a protective cover 4 installed at the telescopic end of the elastic telescopic arm 3, and the protective cover 4 is located directly above the air quality environment monitor 1. The support column 2 is used to support the installation of the air quality environment monitor 1, and the elastic telescopic arm 3 is used to elastically support the protective cover 4, giving the protective cover 4 elastic buffering properties, which can protect the top of the air quality environment monitor 1 and prevent the air quality environment monitor 1 from being damaged by falling debris during tunnel construction.

[0026] As a preferred technical solution in this embodiment, a mounting arm 5 is connected to the bottom end of the support column 2, and a mounting plate 14 is provided at the bottom end of the mounting arm 5, which is used to cooperate with the support column 2 to support and install the air quality environment monitor 1. Specifically, a rotating connection seat 9 is fixed to the bottom end of the support column 2, and an axial hole 10 that is hinged and adapted to the rotating connection seat 9 is opened at the top of the mounting arm 5. A first positioning hole 11 is also opened at the top of the mounting arm 5, and the first positioning hole 11 is located above the axial hole 10. A plurality of second positioning holes 12 are opened on the rotating connection seat 9 around the rotating axis of the mounting arm 5, and a plurality of second positioning holes 12 are opened on the rotating connection seat 9, and a plurality of second positioning holes 12 that can simultaneously penetrate the second positioning holes 12 and the first positioning holes are provided on the rotating connection seat 9. The positioning bolt 13 of the hole 11 passes through the first positioning hole 11 and one of the second positioning holes 12 on the rotating connecting seat 9 at the same time, so that the mounting arm 5 and the support column 2 can be relatively fixed. At this time, the mounting arm 5 and the support column 2 can be used to fix the air quality environment monitor 1. Since there are multiple second positioning holes 12 around the rotating axis of the mounting arm 5, the positioning bolt 13 passes through the second positioning holes 12 at different positions, so that the mounting arm 5 and the support column 2 can be relatively fixed at different angles. As a result, the air quality environment monitor 1 can be supported and installed on the ground or tunnel wall with different inclination angles at the highway tunnel site.

[0027] As a preferred technical solution in this embodiment, the elastic telescopic arm 3 includes a fixed arm 15 fixed on the support column 2, and the end of the fixed arm 15 is vertically bent upward from the back side of the air quality environment monitor 1 and extends to the top of the air quality environment monitor 1. The top of the fixed arm 15 is vertically movably penetrated by a piston arm 16, and a stopper 17 is provided at one end of the piston arm 16 extending into the fixed arm 15. A spring 18 is provided between the stopper 17 and the bottom end of the fixed arm 15. The spring 18 supports the piston arm 16 with elastic force, so that the elastic telescopic arm 3 as a whole elastically supports the protective cover 4, so that the protective cover 4 protects the top of the air quality environment monitor 1. Since the elastic telescopic arm 3 is directly installed on the support column 2, the air quality environment monitor 1 is prevented from being directly subjected to force when gravel falls, thereby further improving the protection effect on the top of the air quality environment monitor 1.

[0028] Furthermore, in this embodiment, the upper surface of the protective cover 4 is arched in an arc shape, and water guide boxes 6 are provided on both sides of the protective cover 4. The bottom of the water guide box 6 gradually slopes downward toward the back side of the air quality environment monitor 1, and a downpipe 7 is connected to the bottom of the water guide box 6 near the back of the air quality environment monitor 1. The upper surface of the protective cover 4 is arched in an arc shape. In addition, the water guide boxes 6 are provided on both sides of the protective cover 4. The groundwater dripping during the tunnel construction process can be guided by the protective cover 4 to the water guide box 6, and then the inclined surface of the bottom wall of the water guide box 6 is used to guide the groundwater to the downpipe 7 and drain from the back side of the air quality environment monitor 1. A convex edge 8 is provided on the upper surface of the protective cover 4 facing the front side of the air quality environment monitor 1. The two ends of the convex edge 8 extend above the water guide box 6. The convex edge 8 can prevent the water dripping on the protective cover 4 from dripping toward the front of the air quality environment monitor 1, thereby effectively preventing the groundwater leaking during the tunnel construction from affecting the air quality environment monitor 1.

[0029] Working principle: When in use, the positioning bolt 13 passes through the first positioning hole 11 and one of the second positioning holes 12 on the rotating connecting seat 9 at the same time to relatively fix the mounting arm 5 and the support column 2. The air quality environment monitor 1 can be fixedly supported and installed by using the mounting arm 5 and the support column 2. Since there are multiple second positioning holes 12 around the rotating axis of the mounting arm 5, the positioning bolt 13 passes through the second positioning holes 12 at different positions, so that the mounting arm 5 and the support column 2 can be relatively fixed at different angles. As a result, the air quality environment monitor 1 can be supported and installed on the ground or tunnel wall with different inclination angles at the highway tunnel site, with high flexibility and adaptability. Furthermore, the spring 18 is used to elastically support the piston arm 16, so that the elastic telescopic arm 3 as a whole elastically supports the protective cover 4, giving the protective cover 4 elastic buffering properties, which can protect the top of the air quality environment monitor 1 and prevent the air quality environment monitor 1 from being damaged by falling debris during tunnel construction. In addition, the upper surface of the protective cover 4 has an arc-shaped arched structure design, and coupled with the water guide box 6 arranged on both sides of the protective cover 4, the groundwater dripping during the tunnel construction process can be guided by the protective cover 4 into the water guide box 6, and then guided to the downpipe 7 by the inclined surface of the bottom wall of the water guide box 6 to be discharged from the back side of the air quality environment monitor 1. The convex edge 8 arranged on the side of the protective cover 4 facing the front side of the air quality environment monitor 1 can prevent the water dripping on the protective cover 4 from dripping toward the front of the air quality environment monitor 1, thereby effectively preventing the influence of groundwater leaking during tunnel construction on the air quality environment monitor 1, and having high protection performance.
