Highway tunnels are located in a complex geological environment and face the pressure of surrounding rocks and loose soil. If they are not stabilized in time, they may cause local collapse, seriously threatening driving safety. Therefore, it is necessary to build a stable structure for the pits entering the tunnels; the pit stabilization structure can effectively reinforce the pits and enhance the stability of the structure, thereby successfully avoiding deformation and damage to the tunnel. However, the traditional pit stabilization structure can only play the role of a single tunnel support. When encountering groundwater infiltration, the lack of a groundwater treatment mechanism can easily lead to groundwater accumulation in the area, which will not only cause erosion and damage to the stable structure itself, reducing its stability and durability, but may also cause increased humidity inside the tunnel or cracks on the inner wall, causing safety hazards to the tunnel.

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0023] Embodiment 1:

[0024] like Figure 1 , 2As shown, the utility model provides a pit stabilizing structure for a highway tunnel, including a stabilizing bracket 11, on which two groups of drainage grooves 12 are provided to guide groundwater; at the same time, multiple groups of water leakage holes 13 are provided on the bottom surface of the drainage grooves 12, and the water leakage holes 13 allow water to pass smoothly. A through groove 14 is also provided on the stabilizing bracket 11, and a drainage assembly is arranged in the through groove 14. The drainage groove 12 is connected with the drainage assembly through the water leakage holes 13, so that water can flow smoothly from the drainage groove 12 through the water leakage holes 13 into the drainage assembly, thereby realizing an efficient drainage function, and can efficiently discharge the infiltrated groundwater in time, avoiding the erosion and damage of the groundwater accumulation to the stabilizing structure, and effectively ensuring the stability and durability. Multiple groups of support rods 15 are also provided inside the stabilizing bracket 11, and the support rods 15 provide strong support and reinforcement for the stabilizing bracket 11, ensuring the stability and strength of its structure. In addition, electric hydraulic rods 21 are provided at both ends of the stabilizing bracket 11, and these electric hydraulic rods 21 are detachably connected to the stabilizing bracket 11. The electric hydraulic rods 21 can adjust the position of the stabilizing bracket 11 and control the supporting force, so that the stabilizing bracket 11 can better adapt to different practical needs and complex environments, and improve the effectiveness and reliability of its application.

[0025] The drainage assembly includes two sets of drainage pipes 31, which are placed inside the stable bracket 11. A plurality of mounting brackets 32 are arranged on the drainage pipes 31. These mounting brackets 32 play an important connecting role, and are connected to the stable bracket 11 by bolts, thereby ensuring the stability and reliability of the drainage pipes 31 in the stable bracket 11. A water receiving groove 33 is provided on one side of the drainage pipe 31, and the drainage groove 12 can be connected to the water receiving groove 33 through the water leakage hole 13. When groundwater accumulates, the water can flow along the drainage groove 12 and smoothly enter the water receiving groove 33 through the water leakage hole 13, thereby preparing for the subsequent drainage work.

[0026] The drainage assembly also includes two groups of collection boxes 34. Two groups of support plates 16 are arranged on one side of the stable bracket 11, and the collection boxes 34 are installed on these support plates 16, so as to obtain stable support. The two ends of the two groups of drainage pipes 31 are connected to the collection boxes 34 through connecting pipes 35, respectively, to construct a complete drainage channel, so that the water entering the water receiving trough 33 can smoothly flow into the collection box 34 through the drainage pipes 31 and the connecting pipes 35. On one side of the collection box 34, there is also a water outlet pipe 36. This water outlet pipe 36 can guide the water accumulated in the collection box 34 to a suitable discharge location to complete the entire drainage process. Through the use of the drainage assembly, groundwater can be efficiently collected and discharged, which can not only timely discharge the infiltrated groundwater, but also avoid the erosion and damage of the stable structure by the accumulation of groundwater, effectively guarantee the stability and durability of the stable bracket 11, and also provide a basis for the normal operation and long-term reliable operation of the entire structure.

[0027] like Figure 2 , 4 As shown in Figures 5 and 6, a mounting seat 22 is provided on the electric hydraulic rod 21, and the stabilizing bracket 11 is clamped in the mounting seat 22, so as to achieve a stable connection between the two. A fixing groove 23 is provided on the mounting seat 22, and a plurality of fixing holes 24 are provided at the bottom of the fixing groove 23 and on the stabilizing bracket 11, and fixing bolts are passed through these fixing holes 24, so as to further strengthen the connection firmness and stability between the mounting seat 22 and the stabilizing bracket 11. In order to enhance the sealing effect, a sealing plate 25 is clamped in the fixing groove 23. Such an arrangement can effectively prevent the intrusion of external impurities or other adverse factors, and ensure the integrity and reliability of the connection structure. At the same time, the gap between the mounting seat 22 and the stabilizing bracket 11 is also carefully filled with sealant, which not only further enhances the sealing effect, but also makes the connection between the two tighter, reducing possible looseness or gaps.

[0028] The opening surface of the water leakage hole 13 is set to be funnel-shaped, which can more effectively guide the flow of water, so that groundwater can enter the drainage component more smoothly through the water leakage hole 13. A reinforcement frame 26 is also provided below the stable bracket 11, and the reinforcement frame 26 is reliably connected to the stable bracket 11 through bolts. The existence of the reinforcement frame 26 provides additional support and reinforcement for the stable bracket 11, further improving the stability and firmness of the entire structure.

[0029] Embodiment 2:

[0030] Based on the pothole stabilizing structure of the highway tunnel provided by the first embodiment of the present application, the second embodiment of the present application proposes a pothole stabilizing structure of the highway tunnel. This second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present utility model will be further described below.

[0031] like Figure 1 , 3 As shown, the drainage assembly also includes two groups of collection boxes 34, and two groups of support plates 16 are arranged on one side of the stable bracket 11, and the collection box 34 is installed on these support plates 16, so as to obtain stable support. The two ends of the two groups of drainage pipes 31 are connected to the collection box 34 through the connecting pipe 35, respectively, to construct a complete drainage channel, so that the water entering the water receiving trough 33 can smoothly flow into the collection box 34 through the drainage pipe 31 and the connecting pipe 35. On one side of the collection box 34, there is also a water outlet pipe 36. This water outlet pipe 36 can guide the water accumulated in the collection box 34 to a suitable discharge location to complete the entire drainage process. Through the use of the drainage assembly, groundwater can be efficiently collected and discharged, which can not only timely discharge the infiltrated groundwater, but also avoid the erosion and damage of the stable structure by the accumulation of groundwater, effectively guarantee the stability and durability of the stable bracket 11, and also provide a basis for the normal operation and long-term reliable operation of the entire structure. In order to further improve the drainage efficiency and effect, a vacuum generator 37 is detachably provided on the collection box 34, and the vacuum generator 37 is tightly connected to the collection box 34 through a connecting conduit. The vacuum generator 37 can generate a certain vacuum suction force to speed up the flow of water into the collection box 34, thereby improving the working efficiency of the entire drainage system. It can effectively respond to different situations and needs, whether facing a large amount of groundwater accumulation or under complex and changeable environmental conditions, and can ensure the smooth progress of drainage work, providing a guarantee for the stability and safety of related facilities and structures.

[0032] The difference between the second embodiment and the first embodiment is that a vacuum generator 37 is installed on the collection box 34, and the vacuum generator 37 is connected to the collection box 34 through a connecting conduit. When the vacuum generator 37 starts to work, it will generate a negative pressure state inside the collection box 34, forming a certain attraction, so that the groundwater in the drainage pipe 31 can enter the collection box 34 more smoothly and quickly. The attraction generated by this negative pressure can effectively overcome the various resistances and obstacles that groundwater may encounter during the flow process. It can make the groundwater surge toward the direction of the collection box 34 more actively and proactively, reducing the situation of poor drainage caused by pipeline resistance or other factors. At the same time, this attraction can also enhance the stability and reliability of the entire drainage system, ensuring that the groundwater can be smoothly collected and processed according to the designed path and method. The remaining conditions are consistent with the first embodiment, so this embodiment will not be repeated.

[0033] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
