Description

Technical Field

[0001] This invention relates to the field of utility tunnel technology, and in particular to a prefabricated grid energy dissipation structure for underground utility tunnels. Background Technology

[0002] Underground utility tunnels refer to structures and ancillary facilities located below urban ground level to accommodate two or more types of public utility pipelines or specialized pipelines. Public utility pipelines include power, communication (including monitoring lines), radio and television, water supply, drainage, heating, gas, fire protection pipelines, traffic signals, emergency optical cables, etc. Ancillary facilities include drainage, ventilation, lighting, electrical, communication, fire protection, safety monitoring systems, and monitoring and management rooms used to maintain the normal operation of the utility tunnel.

[0003] Energy dissipation bar screens in utility tunnels are a structural design primarily used to reduce and disperse the energy generated by water flow through pipes or ditches, preventing erosion and improving the safety of water flow control. Prefabricated energy dissipation bar screens are an efficient and convenient design and construction method used in modern utility tunnel construction. These screens are typically prefabricated in a factory and assembled on-site, significantly accelerating project progress and ensuring quality. Energy dissipation bar screens are usually installed in the downstream section of the utility tunnel, using a series of staggered bar screens or similar structures to increase water flow turbulence, thereby slowing the flow velocity and reducing impact force. However, existing screens are fixedly connected and not adjustable, meaning the degree of energy dissipation cannot be adjusted by modifying the screen itself. Summary of the Invention

[0008] Preferably, the second energy-dissipating grille is slidably connected to the inner wall of the ground drainage pipe, and a corrugated sealing sleeve is provided between the second mounting plate and the top of the control box, with the mounting platform located inside the corrugated sealing sleeve.

[0009] Preferably, the top of the energy dissipation box is provided with an energy dissipation inlet connected to the ground drainage pipe, and the bottom of the energy dissipation box is provided with an energy dissipation outlet connected to the pipe gallery drainage pipe.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should be understood in their ordinary sense by those skilled in the art. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate the invention and are not intended to limit the scope of the invention.

[0023] Example

[0024] like Figure 1 As shown, this invention provides a prefabricated grid energy dissipation structure for underground utility tunnels, including a utility tunnel 1 and a ground drainage pipe 2 entering the utility tunnel 1. A grid energy dissipation unit is provided between the ground drainage pipe 2 and the utility tunnel drainage pipe 3. The top of the energy dissipation box 4 of the grid energy dissipation unit is connected to the top of the utility tunnel 1, and the utility tunnel drainage pipe 3 is connected to the drainage support 6 at the bottom of the utility tunnel 1. A utility tunnel water supply pipe 7 is provided on the other side of the utility tunnel drainage pipe 3. A first energy dissipation grid 41 is connected to the lower side wall of the energy dissipation box 4, and a second energy dissipation grid 42 is connected to the mounting platform 439 on the top of the energy dissipation box 4. The second energy dissipation grid 42 is located inside the ground drainage pipe 2.

[0025] After removing large particles of impurities, the water from the ground drainage pipe 2 enters the bar grid energy dissipation unit. The structure for removing large particles is existing technology and will not be described in detail here. The bar grid energy dissipation unit dissipates energy from the water in the ground drainage pipe 2, and the dissipated water then enters the pipe gallery drainage pipe 3. The first energy dissipation bar 41 performs primary energy dissipation, and the second energy dissipation bar 42 performs secondary energy dissipation. The second energy dissipation bar 42 can rotate relative to the first energy dissipation bar 41 to change the path of the falling water, thereby adjusting the degree of energy dissipation. The bar grid energy dissipation unit is detachably connected to the ground drainage pipe 2 and the pipe gallery drainage pipe 3, facilitating independent replacement of all three and saving maintenance time and costs.

[0026] like Figure 2 and Figure 3As shown, a first mounting plate 411 is located in the center of the first energy dissipation grille 41. A control box 43 is mounted on the first mounting plate 411. Inside the control box 43, a lifting chamber 431 and a rotating chamber 434 are arranged sequentially from top to bottom. A rotating motor 435 is located at the bottom of the rotating chamber 434. A lifting rack 433 is sleeved on the rotating rod 436 connected to the rotating motor 435. The mounting bracket on the side wall of the lifting chamber 431 is connected to the lifting motor 432. The lifting motor 432 is connected to a gear 4311, and the lifting rack 433 meshes with the gear 4311.

[0027] The first energy-dissipating grid 41 is connected to the side wall of the energy-dissipating box 4, which is a cylindrical box to ensure smooth connection with the ground drainage pipe 2 and the pipe gallery drainage pipe 3. The control box 43 is used to adjust the position of the second energy-dissipating grid 42 and its angle relative to the first energy-dissipating grid 41, thereby adjusting the energy dissipation level of the energy-dissipating box 4.

[0028] The lifting motor 432 is started, driving the gear 4311 to rotate. The gear 4311 drives the lifting rack 433 to move up and down. The lifting rack 433, through the mounting platform 439, drives the second energy-dissipating grid 42 to move up and down, adjusting the distance between the first energy-dissipating grid 41 and the second energy-dissipating grid 42. The lifting rack 433 is evenly provided with several horizontally arranged rack rings. The gaps between adjacent rack rings mesh with the teeth of the gear 4311. The rack rings ensure that even after the lifting rack 433 rotates, the gear 4311 can still drive the lifting rack 433 to move up and down.

[0029] like Figure 4 As shown, a positioning block 437 is provided at the top of the rotating rod 436. The positioning block 437 is slidably connected to the positioning groove 438 inside the lifting rack 433. The positioning groove 438 and the rotating rod 436 are horizontally arranged. The upper part of the lifting rack 433 passes through the energy dissipation box 4 and is connected to the mounting platform 439. The mounting platform 439 is connected to the second mounting plate 421 in the center of the second energy dissipation grid 42.

[0030] The rotating motor 435 is started, driving the rotating rod 436 to rotate. The rotating rod 436, through the positioning block 437 and the positioning groove 438, drives the lifting rack 433 to rotate with the rotating rod 436, adjusting the angle between the grid bars of the second energy-dissipating grid 42 and the grid bars of the first energy-dissipating grid 41, thereby adjusting the energy dissipation effect of the first energy-dissipating grid 41 and the second energy-dissipating grid 42. A through hole is provided between the lifting cavity 431 and the rotating cavity 434 to facilitate the rotation or up-and-down movement of the lifting rack 433.

[0031] The second energy dissipation grille 42 is slidably connected to the inner wall of the ground drainage pipe 2. A corrugated sealing sleeve 4310 is provided between the second mounting plate 421 and the top of the control box 43, and the mounting platform 439 is located inside the corrugated sealing sleeve 4310. The corrugated sealing sleeve 4310 is designed to waterproof the control box 43 during the movement of the lifting rack 433, preventing water from entering the control box 43 and affecting the adjustment of the angle and position of the second energy dissipation grille 42. The corrugated sealing sleeve 4310 is slidably connected to the annular groove of the second mounting plate 421, ensuring that the corrugated sealing sleeve 4310 remains connected to the second energy dissipation grille 42 during its rotation.

[0032] The energy dissipation box 4 has an energy dissipation inlet 44 at the top that connects to the ground drainage pipe 2, and an energy dissipation outlet 45 at the bottom that connects to the pipe gallery drainage pipe 3. The energy dissipation box 4 is located between the ground drainage pipe 2 and the pipe gallery drainage pipe 3, and sealing rings are provided at the connection points of the three to seal the ground drainage pipe 2 and the pipe gallery drainage pipe 3, preventing water from flowing out from the connection points of the energy dissipation box 4 with the ground drainage pipe 2 and the pipe gallery drainage pipe 3.

[0033] The first energy-dissipating grille 41 has downward-protruding arc-shaped bars, and the connection between the first mounting plate 411 and the control box is horizontal. The downward-protruding design of the first energy-dissipating grille 41 buffers the impact force of falling water, and the horizontal design of the first mounting plate 411 facilitates a stable connection with the control box 43.

[0034] The second energy-dissipating grille 42 has downward-protruding arc-shaped bars, and the connection between the second mounting plate 421 and the mounting platform 439 is horizontal. The downward-protruding design of the second energy-dissipating grille 42 buffers the impact force of falling water, and the design of the second mounting plate 421 facilitates a stable connection with the mounting platform 439.

[0035] Power cables 5 are installed on the side wall of the integrated utility tunnel 1.

[0036] The metal control box 43 is equipped with a maintenance door, and a sealing strip is installed between the maintenance door and the control box 43. Sealing strips are also installed at all gaps in the control box 43, and a sealing ring is installed between the lifting rack 433 and the top side wall of the control box 43. The installation of sealing strips and sealing rings ensures that no water enters the control box 43 and affects its normal operation.

[0037] Therefore, the present invention adopts an underground utility tunnel prefabricated grid energy dissipation structure with the above-mentioned structure. The control box can control the distance between the second energy dissipation grid and the first energy dissipation grid and the overlap angle between the grid bars of the two grids to adjust the energy dissipation degree of the grid energy dissipation unit.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
