Description

Technical Field

[0001] This application relates to the field of tunnel protection technology, and in particular to a protective canopy structure for the entrance of a hydraulic tunnel. Background Technology

[0002] During the construction of hydraulic tunnels, the tunnel entrances and exits are often used as access channels for personnel and equipment. However, the rolling of unstable rocks on the tunnel entrance slope is a major cause of danger as personnel and equipment enter the tunnel. In addition to supporting the slope, erecting a tunnel entrance protective shed is a common method of tunnel entrance protection, which can effectively ensure the safety of personnel and equipment.

[0003] Common existing protective shed construction methods include wooden frame sheds and steel pipe frame sheds, which are then fully covered with bamboo mats or scaffold boards. Wooden frame sheds are relatively simple and inexpensive to construct, but their strength and durability are relatively poor. Steel pipe frame sheds, on the other hand, have higher strength and stability, can withstand greater impact, and have a longer service life, but they are more expensive, their dimensions are difficult to control, and their curved structure makes on-site cutting and welding inconvenient. Furthermore, the current practice of personnel and equipment sharing the same access passage easily leads to congestion and poses certain safety hazards. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a protective canopy structure for the entrance of a hydraulic tunnel, which is installed at the construction site as a pedestrian-machine separation channel to ensure the safety of personnel and equipment near the entrance of the hydraulic tunnel and those entering and exiting the tunnel.

[0005] The first aspect of this application provides a protective canopy structure for the entrance of a hydraulic tunnel, comprising: embedded parts, uprights, horizontal bars, side bars, diagonal braces, and stiffening plates. The horizontal bars are horizontally spaced and connected to the side bars to form a rectangular template. The two ends of the horizontal bars are respectively connected to the uprights. Diagonal braces connect the uprights and the horizontal bars, forming an equipment passage between the uprights. The rectangular template is stably erected at the tunnel entrance based on the embedded parts installed at the bottom of the uprights. A protective plate is laid on the top of the rectangular template. Side bars are also installed between the uprights. The side bar farthest from the tunnel entrance forms a pedestrian entrance with the uprights. Stiffening plates are installed at the corners where the uprights connect to the side bars and the horizontal bars.

[0006] One side of the equipment passage is equipped with a turnstile corresponding to the pedestrian entrance. The turnstile is connected to the pedestrian entrance through a protective railing to form a pedestrian passage.

[0007] The embedded parts include an embedded plate and components spaced apart at the bottom of the embedded plate. Shaped rod.

[0008] The rectangular template has a fan bracket at the top, which is used to install the fan equipment.

[0009] The technical solution provided in this application may include the following beneficial effects:

[0010] This application provides a protective canopy structure for the entrance of a hydraulic tunnel, which is easy to produce and install on the construction site, has good structural strength and durability, and after being erected, can not only protect the entrance but also serve as a passage for the separation of people and machinery, effectively ensuring the safety of personnel and equipment near the entrance of the hydraulic tunnel and those entering and exiting the tunnel.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, according to the size of the tunnel entrance and the protection requirements, a protective canopy structure is erected at the entrance of the hydraulic tunnel, including: embedded parts 5, uprights, horizontal bars 2, side bars 4, diagonal braces 3, and stiffening plates 6. The horizontal bars 2 are horizontally spaced and connected to the side bars 4 to form a rectangular template. The two ends of the horizontal bars 2 are respectively connected to the uprights 1. The uprights 1 and the horizontal bars 2 are connected by diagonal braces 3, and the uprights 1 form an equipment passage. The rectangular template is stably erected at the tunnel entrance based on the embedded parts 5 installed at the bottom of the uprights 1. The top of the rectangular template is covered with a protective plate 7. Side bars 4 are also installed between the uprights 1. The side bar 4 farthest from the tunnel entrance forms a pedestrian entrance with the uprights 1. Stiffening plates 6 are installed at the corners where the uprights 1 connect to the side bars 4 and the horizontal bars 2.

[0026] In one specific embodiment, the specific parameters of the components are as follows: the upright 1 is an I14 I-beam with a length of 3.40m; the horizontal bar 2 is an I14 I-beam with a length of 4.08m; the diagonal brace 3 is an I14 I-beam with a length of 1.50m; the side bar 4 is an I14 I-beam with a length of 1.63m; the embedded part 5 includes a square steel plate with a side length of 20cm and a thickness of 1cm, on which two parallel steel bars are welded at 3cm intervals on all four sides. The steel bar is C22 in shape, with a horizontal length of 14cm and two other side lengths of 17cm, totaling 48cm; the stiffening plate 6 is an isosceles right triangle with a right angle side length of 20cm and a thickness of 1cm.

[0027] Installation process of the protective canopy structure:

[0028] 1. Within 5m of the opening, 8 embedded plates are pre-embedded in the poured concrete of the site according to the drawings. The horizontal and vertical spacing is 408cm×163cm. 8 uprights are welded on each plate to serve as the main structure for the vertical support of the device.

[0029] 2. Use side rods 4 to weld and connect adjacent uprights on the same side. The connection position is the midpoint of the uprights (the welding height of side rod 4 between the two uprights 1 on the left side furthest from the opening is 2.4m above the ground, serving as a passage for subsequent personnel to enter the site), and use stiffening plates 6 to weld and reinforce the corner of the connection.

[0030] 3. The protective structure at the top of the protective shed uses horizontal bars 2 to connect the uprights 1 on both sides, with a total of 4 horizontal bars 2. Diagonal braces 3 are used to reinforce the horizontal bars 2 and the uprights on both sides by welding, forming a solid structure. Side bars 4 are used to connect the horizontal bars 2 on the same side, with the connection positions being the two ends and the midpoint of the horizontal bars 2. Stiffening plates 6 are used to reinforce the corners on both sides by welding, with a total of 9 side bars 4 and 12 stiffening plates 6.

[0031] 4. Before implementing protective measures, the ventilation fans used for ventilation inside the tunnel can be installed above the protective canopy, such as... Figure 5 As shown, the fan bracket 8 is installed and connected securely on the top of the protective shed by welding or other methods. The air duct is arranged along the top of the hole, and the remaining space on the top of the protective shed is fully covered with 5cm thick wooden boards or other protective facilities.

[0032] 5. A duty room, a real-name gate, and protective railings are set up on the right side of the protective canopy as a pedestrian passage. Personnel enter the tunnel along the inner side of the protective railings, while the outer side serves as a passage for mechanical equipment, thus achieving the function of separating pedestrians and vehicles. Figure 4 As shown.

[0033] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
