Description

Technical Field

[0001] The utility model relates to the technical field of tunnel anti-condensation, in particular to an anti-condensation structure for the inner wall of a highway tunnel. Background Art

[0002] In tunnel engineering, in order to ensure the safety and dryness inside the tunnel, we need to set up circumferential and longitudinal drainage channels in the constructed tunnel wall. Usually, the circumferential drainage channel is connected with the longitudinal drainage channel to form a complete drainage system. These channels are designed as permeable structures to effectively discharge the accumulated water behind the tunnel lining through the outlet of the longitudinal drainage channel to the trenches on both sides of the tunnel, thereby reducing the water pressure behind the lining structure.

[0003] However, although the existing tunnel technology has achieved the basic effects of waterproofing and drainage, in highway tunnels, due to the temperature difference between the inside and outside, water vapor often condenses into dew on the inner wall of the tunnel. In addition, the increase in humidity inside the tunnel will further increase the risk of dew on the inner wall. These accumulated dew will drip directly onto the tunnel floor, making the ground slippery and posing a potential safety threat to passing vehicles and pedestrians. What's more serious is that the dew will also slide down the inner wall of the tunnel, which may affect the lighting equipment installed on the inner wall of the tunnel, causing a decrease in lighting effect or damage to the equipment.

[0004] Therefore, although the existing tunnel drainage structure can handle the problem of water seepage and leakage inside the tunnel, it is powerless to prevent and deal with the dew on the inner wall of the tunnel. This has become an important problem that needs to be solved in tunnel engineering. Utility Model Content

[0005] In order to overcome the defects of the prior art, a highway tunnel inner wall anti-condensation structure is now provided to solve the problem that the existing highway tunnels lack preventive treatment for condensation, resulting in safety hazards to tunnel lighting and passing vehicles or people.

[0006] To achieve the above-mentioned purpose, a highway tunnel inner wall anti-condensation structure is provided, comprising: a mounting frame and a sealing box, the mounting frame is provided with a through hole cavity, and a hollow box is installed in the through hole cavity, and a desiccant is provided in the hollow box, the sealing box is installed on the outer wall of the mounting frame, and a fan is installed in the sealing box through a fixing rod, and the sealing box is located on the outside of the through hole cavity, and at the same time, the outer wall of the sealing box is connected to a connecting pipe, the outer end of the connecting pipe is connected to an air outlet pipe, and the pipe wall of the air outlet pipe is provided with an air outlet hole.

[0007] Furthermore, the mounting frame is configured as an arched structure, and outwardly protruding mounting corners are provided on both sides of the bottom of the mounting frame, and the mounting corners are inserted into pre-installation holes opened on the inner wall of the tunnel.

[0008] Furthermore, a fixing block is welded on the outer side of the installation angle, and a fixing bolt is screwed inside the fixing block.

[0009] Furthermore, an isolation net is provided at a cavity opening on one side of the through hole cavity facing the center of the tunnel, a lighting lamp is provided on the inner side of the isolation net, and a waterproof and breathable membrane and a dustproof net are provided on the outer side of the lighting lamp.

[0010] Furthermore, the waterproof breathable membrane and the dustproof net are connected to form an integral structure, and the dustproof net is configured as an arc-shaped structure, and the dustproof net covers the outside of the cavity opening of the through hole cavity.

[0011] Furthermore, the sealing box is installed outside the cavity opening on the side of the through hole cavity facing the inner wall of the tunnel, and the shell of the sealing box is provided with a connecting hole, and one end of the connecting pipe is connected to the connecting hole.

[0012] Furthermore, the sealing box and the illuminating lamp are installed equidistantly along the arc direction of the mounting frame, and a sealing box and a illuminating lamp are installed on the inner and outer sides of the mounting frame respectively.

[0013] The beneficial effects of the utility model are:

[0014] 1. When in use, the mounting frame is installed as a whole on the inner side of the highway tunnel and close to the inner wall through the mounting angle, fixing block and fixing bolts, while keeping a certain distance from the inner wall of the tunnel. Then, through the through hole cavity and the dustproof net, the fan can be started to draw air from the outside to the inside of the sealed box. At this time, since the lighting lamp is on the air flow route, the heat generated by the lighting lamp is brought into the sealed box together with the air. At the same time, the air is dried by the desiccant in the hollow box, and then the dry hot air is blown to the inner wall of the tunnel through the connecting hole, connecting pipe and air outlet pipe, thereby reducing the temperature difference between the inner wall of the tunnel and the external environment. In addition, the rapid flow of air on the inner wall surface can avoid condensation on the inner wall of the tunnel.

[0015] 2. The dust-proof net and waterproof breathable membrane are used to filter the air inside the tunnel into the sealed box during the fan exhaust process, and to intercept more moisture in the air to keep the air clean. At this time, the airflow passing through the lighting lamp not only takes away the heat of the lighting lamp, but also achieves a continuous cooling effect on the lighting lamp. Then, through the porous structure of the hollow box, the air passes through the hollow box and is dried by the desiccant inside. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Reference Figures 1 to 4 As shown, the utility model provides an anti-condensation structure for the inner wall of a highway tunnel, comprising: a mounting frame 1 and a sealing box 2, a through hole cavity 11 is opened inside the mounting frame 1, and a hollow box 12 is installed inside the through hole cavity 11, and a desiccant 13 is arranged inside the hollow box 12, the sealing box 2 is installed on the outer wall of the mounting frame 1, and a fan 22 is installed inside the sealing box 2 through a fixing rod 23, and the sealing box 2 is located outside the through hole cavity 11, and at the same time, a connecting pipe 211 is connected to the outer wall of the sealing box 2, and an outer end of the connecting pipe 211 is connected to an air outlet pipe 212, and an air outlet hole 213 is opened on the pipe wall of the air outlet pipe 212.

[0022] In this embodiment, the mounting frame 1 and the sealing box 2 constitute the main body of the anti-condensation structure for the inner wall of the highway tunnel involved in this application, and the lighting lamp 5 installed on the inner side of the mounting frame 1 increases the practical use function.

[0023] Specifically, the hollow box 12 is configured as a detachable structure, and the hollow box 12 is provided with a detachable box cover, so as to facilitate regular replacement of the internal desiccant 13 .

[0024] Specifically, the mounting frames 1 are arranged equidistantly in the length direction of the tunnel, and both ends of the air outlet pipe 212 are blocked and fixed between adjacent mounting frames 1, while the connecting pipe 211 is connected to the outer wall of the air outlet pipe 212 and communicated with the internal tube cavity.

[0025] Through the above technical solution, when dry hot air is ejected through the connecting pipe 211 and the air outlet holes 213 of the air outlet pipe 212, the ejected hot air passes through the inner wall of the tunnel to form a diffusion surface, and multiple air outlet holes 213 eject hot air at the same time, so that the diffusion surfaces are connected, and then the entire inner wall of the tunnel is blown by the hot air flow, achieving an anti-condensation effect.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, the mounting frame 1 is configured as an arch structure, and outwardly protruding mounting angles 14 are provided on both sides of the bottom of the mounting frame 1, and the mounting angles 14 are inserted into pre-installation holes opened on the inner wall of the tunnel, and a fixing block 15 is welded on the outer side of the mounting angle 14, and a fixing bolt 16 is screwed inside the fixing block 15, and an isolation net 6 is provided on the side of the through hole cavity 11 facing the center of the tunnel, and a lighting lamp 5 is provided on the inner side of the isolation net 6, and a waterproof and breathable membrane 4 and a dustproof net 3 are provided on the outer side of the lighting lamp 5, the waterproof and breathable membrane 4 is connected to the dustproof net 3 as an integral structure, and the dustproof net 3 is configured as an arc structure, and the dustproof net 3 covers the outer side of the cavity opening of the through hole cavity 11.

[0027] Specifically, a protruding plug-in angle is provided on the top of the mounting frame 1 so that it can be positioned and plugged into a plug-in hole reserved on the inner wall of the tunnel top during installation, thereby enhancing the stability of the mounting frame 1.

[0028] Specifically, the lighting lamp 5 is configured as an LED lamp, including a lamp bead and a transparent cover.

[0029] Through the above-mentioned ending scheme, the isolation protection and dustproof effect of the lighting lamp 5 are achieved by setting the isolation net 6 and the dustproof net 3, and the waterproof breathable membrane 4 prevents large water vapor in the air from entering the interior of the lighting lamp 5 to cause adverse effects.

[0030] like Figure 1 and Figure 2 As shown in the figure, the sealing box 2 is installed on the outer side of the cavity opening of the through hole cavity 11 facing the inner wall of the tunnel, and the shell of the sealing box 2 is provided with a connecting hole 21, and one end of the connecting pipe 211 is connected to the connecting hole 21, the sealing box 2 and the lighting lamp 5 are installed equidistantly along the arc direction of the mounting frame 1, and a sealing box 2 and a lighting lamp 5 are respectively installed on the inner and outer sides of the mounting frame 1.

[0031] Through the above technical scheme, the air in the sealing box 2 is discharged in a direction by opening a connecting hole 21, and at the same time, multiple groups of lighting lamps 5 and the sealing box 2 are connected one by one, so that on the basis of realizing the internal lighting of the tunnel, the heat generated by the lighting lamps 5 can achieve the effect of blowing and moisture-proofing inside the tunnel, thereby reasonably utilizing equipment resources.

[0032] When in use, the mounting frame is installed as a whole on the inner side of the highway tunnel and close to the inner wall through the mounting angles, fixing blocks and fixing bolts, while keeping a certain distance from the inner wall of the tunnel. Then, through the through-hole cavity and the dust-proof net, the fan can be started to draw air from the outside into the sealed box. At this time, since the lighting lamp is on the air flow route, the heat generated by the lighting lamp is brought into the sealed box together with the air. At the same time, the air is dried by the desiccant in the hollow box. Then, the dry hot air is blown to the inner wall of the tunnel through the connecting holes, connecting pipes and air outlet pipes, thereby reducing the temperature difference between the inner wall of the tunnel and the external environment. In addition, the rapid flow of air on the inner wall surface can avoid condensation on the inner wall of the tunnel.

[0033] The anti-condensation structure for the inner wall of a highway tunnel of the utility model can effectively solve the problem that the existing highway tunnels lack preventive treatment for condensation, which causes potential safety hazards to tunnel lighting and passing vehicles or people. It is realized on the basis of the existing anti-condensation structure technology for the inner wall of a highway tunnel, that is, lighting can be achieved for the tunnel, and at the same time, heat can be generated by the lighting to prevent condensation on the inner wall of the tunnel, thereby avoiding the potential safety hazards to passing vehicles and pedestrians caused by the slippery interior of the tunnel.
