Description

Technical Field

[0001] This utility model relates to the field of protective canopy technology, specifically to a protective canopy for tunnel water inrush and mudslide. Background Technology

[0002] During tunnel construction, water inrush and mudslide are extremely difficult and frequent problems. When tunnels pass through adverse geological areas such as karst caves, fault fracture zones, and water-rich rock strata, they are highly susceptible to the threat of water inrush and mudslide.

[0003] The occurrence of water inrush and mud inrush has widespread hazards. It not only seriously threatens the lives of construction workers, but may also damage construction equipment, significantly delay the construction progress, and greatly increase project costs. In particular, when there is a road below the tunnel, if the water inrush and mud inrush break through the tunnel lining, the mud and water will flow down and directly impact the road below, thus seriously affecting the normal passage of the road. At present, traditional protective measures for dealing with the impact of water inrush and mud inrush on the road below have many shortcomings. For example, some temporary protective structures have poor stability and sealing, making it difficult to effectively block the leakage of mud and water, and are not conducive to guiding the water to the sides.

[0004] Therefore, in order to address emergency treatment and ensure passage in tunnels, it is necessary to effectively isolate the risks posed by water inrush and mud inrush during tunnel construction, reduce the workload of workers, and provide a relatively safe working environment for construction personnel. In view of this, we propose a tunnel water inrush and mud inrush protection canopy. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings mentioned in the background art and provide a protective canopy for tunnel water inrush and mudslide.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A tunnel water inrush and mudslide protection canopy includes:

[0008] The inverted U-shaped frame includes two vertical steel frames fixedly connected at the top by a horizontal steel frame, and diagonal braces are installed on both the vertical and horizontal steel frames.

[0009] Two side limiting components are vertically and symmetrically installed on the horizontal steel frame;

[0010] A corrugated plate assembly, installed between the two side limiting assemblies, is used to protect against water inrush and mud inrush in the tunnel.

[0011] Preferably, the side limiting assembly includes an outer fixing plate that can be detachably installed on the horizontal steel frame, and a limiting plate can be detachably installed on the inner side of the outer fixing plate;

[0012] A vertical guide groove is vertically provided in the middle of the limiting plate.

[0013] Preferably, the corrugated plate assembly includes two symmetrically arranged side corrugated plates, and the two side corrugated plates are provided with connecting end blocks that are staggered on the corresponding sides, and a rotating shaft is rotatably mounted on the connecting end blocks;

[0014] The rotating shaft is inserted into the vertical guide groove.

[0015] Preferably, a lifting cylinder for lifting the corrugated plate assembly is installed at the middle of the horizontal steel frame.

[0016] Preferably, the limiting plate is provided with horizontal grooves on both sides, and a roller is horizontally and rotatably mounted between the two horizontal grooves.

[0017] The rollers on both sides respectively support the outer ends of the two side corrugated plates.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The tunnel water inrush and mud inrush protection canopy, through the inverted U-shaped frame body and the corrugated plate assembly, can form a canopy protection structure, which can cope with the water inrush and mud inrush problems of the tunnel above, and is conducive to improving protection. The use of this device can reduce the probability of construction personnel being directly exposed to the risks of water inrush and mud inrush, and further protect the life safety of construction personnel.

[0020] 2. The side limiting component can be installed with the corrugated plate component. Under the action of the power source, the arch support adjustment of the corrugated plate component can be realized, which is conducive to guiding the water and mud inrush to both sides of the tunnel and avoiding the situation of excessive load on the corrugated plate after bearing the water and mud inrush.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Please see Figures 1-6 The present invention will describe the above technical solution in detail through the following embodiments:

[0033] This embodiment of the tunnel water inrush and mudslide protection canopy is used to provide protection inside the tunnel, preventing potential localized water inrush and mudslides on the tunnel wall during construction, thus ensuring the safety and protection performance of the passage below. Specifically, it includes:

[0034] Inverted U-shaped frame section, such as Figures 1-4 The structure shown in this embodiment includes two vertical steel frames 1 that are fixedly connected at the top by a horizontal steel frame 3. The vertical steel frame 1 and the horizontal steel frame 3 are quadrilateral structures. In order to improve the reliability of the structure, diagonal braces 2 are installed on both the vertical steel frame 1 and the horizontal steel frame 3.

[0035] In this embodiment, side limiting components 4 are vertically and symmetrically installed at the front and rear ends of the horizontal steel frame 3, and a corrugated plate assembly 5 is installed between the two side limiting components 4, forming a protective barrier above the tunnel passage through the corrugated plate assembly 5.

[0036] Specifically, such as Figure 6As shown in the structure, in this embodiment, the side limiting component 4 includes an outer fixing plate 41 that can be detachably installed on the horizontal steel frame 3, and a limiting plate 42 can be detachably installed on the inner side of the outer fixing plate 41. In this embodiment, the limiting plate 42 has an isosceles trapezoidal structure; a vertical guide groove 421 is vertically provided in the middle of the limiting plate 42.

[0037] like Figure 5 As shown in the structure, the corrugated plate assembly 5 in this embodiment includes two symmetrically arranged side corrugated plates 51. The two side corrugated plates 51 are offset from each other and have connecting end blocks 52. A rotating shaft 53 is rotatably installed on the connecting end block 52, that is, the rotating shaft 53 is inserted into the vertical guide groove 421. A lifting cylinder is installed between the connecting end block 52 and the horizontal steel frame 3. The lifting cylinder can lift the corrugated plate assembly 5 to form a triangular slope structure, which can guide the gushing water and mud to both sides, thereby playing a protective role and effect on the road.

[0038] It should be noted that, during the lifting process, in order to reduce wear on the outer ends of the two side corrugated plates 51, horizontal grooves 422 are provided on both sides of the limiting plate 42 in this embodiment, and rollers 6 are horizontally sliding and rotatably mounted between the two horizontal grooves 422. The rollers 6 on both sides can support the outer ends of the two side corrugated plates 51. Figure 4 The structure shown reduces wear and tear, and the lifting height can be adjusted according to actual needs during use.

[0039] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
