Description

Technical Field

[0001] This application relates to the field of tunnel excavation and support technology, and in particular to a hydraulic tunnel excavation and support structure. Background Technology

[0002] Tunnel excavation refers to the engineering process of loosening, breaking, excavating, and transporting excavated soil or rock during tunnel construction. It is widely used in water conservancy projects for water diversion, drainage, flow control, transportation, and other tunnel construction. Tunnel construction is characterized by narrow working faces, poor working conditions, numerous procedures, and significant interference. It is particularly prone to safety accidents, necessitating thorough geological exploration beforehand to rationally select the locations of tunnel entrances and adits, excavated material transportation routes, and tunnel excavation methods. Tunnel excavation mainly includes tunneling, excavation, safety support, and auxiliary operations such as ventilation, water, and electricity supply, as well as ventilation and drainage.

[0003] If the tunnel excavation support structure is ineffective and has weak load-bearing capacity, it is prone to collapse accidents during the excavation process. Therefore, the support structure cannot effectively guarantee the stability of the tunnel, thereby increasing the probability of danger to the operators.

[0004] Therefore, this application proposes a hydraulic tunnel excavation support structure. Utility Model Content

[0005] This application proposes a hydraulic tunnel excavation support structure to solve the problems mentioned in the background art. By setting up support mechanisms, load-bearing mechanisms, and reinforcement mechanisms, the thickness of the middle zone is greater than that of the side zones. Therefore, by deepening the core strength of the support frame, the support frame has strong support force and is not easily affected by gravity, resulting in disintegration or collapse. This reduces the probability of collapse during excavation and the probability of danger to operators, thereby effectively ensuring the stability of the tunnel. I-beams are steel materials with an I-shaped cross-section, possessing high strength and rigidity. Their strength and stability ensure the safety and stability of the structure, increasing the rigidity and stability of the support frame, preventing loosening, displacement, or deformation during construction, and greatly improving the practicality of the device.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A hydraulic tunnel excavation support structure includes a tunnel and a ground surface. The tunnel is located at the top of the ground surface. A support mechanism is installed inside the tunnel. The support mechanism includes a support frame and support plates. Two support plates are fixedly connected to the support frame, and the two support plates are movably installed on the ground surface. The support frame is divided into a middle section and side sections. The middle section is located in the middle of the support frame, and side sections are provided on both sides of the middle section. The support thickness of the middle section is greater than that of the side sections.

[0008] In a preferred embodiment, the support frame is provided with a load-bearing mechanism, which includes an I-beam and is fixedly connected to the middle area inside the support frame.

[0009] By setting up a load-bearing mechanism and I-beams, I-beams are a type of steel with an I-shaped cross-section. They are called "I-beams" because of their strong ability to withstand pressure and tension. They are mainly made of carbon steel, low alloy steel, and high-strength steel, and have high strength and rigidity. Their strength and stability can ensure the safety and stability of the structure, thereby improving the practicality of the device.

[0010] In a preferred embodiment, the support frame is provided with a reinforcement mechanism, which includes reinforcement plates and reinforcement bars. Both reinforcement plates are located in the side area of ​​the support frame, and multiple reinforcement bars are inserted inside the two reinforcement plates.

The waterproof layer is provided on the exterior of the support frame, and the wear-resistant layer is provided on the exterior of the waterproof layer.

[0013] By incorporating protective mechanisms, wear-resistant layers, and waterproof layers, the support frame possesses certain wear-resistant and waterproof properties during construction, thereby extending its service life, ensuring its quality, and ultimately enhancing the practicality of the device.

[0014] In a preferred embodiment, both support plates are provided with a moving mechanism, which includes a groove and a moving wheel. Each groove is formed inside the support plate, and a moving wheel is slidably connected inside each groove. The outside of each moving wheel is in contact with the ground.

[0015] By incorporating a moving mechanism, grooves, and wheels, the mobility and convenience of the support mechanism during use are improved, thereby enhancing the practicality of the device.

[0016] In a preferred embodiment, the bottom of the two support plates is provided with multiple sets of ground-piercing mechanisms, each set of ground-piercing mechanisms including ground spikes, each set of ground spikes being provided at the bottom of the support plate and each set of ground spikes being driven into the ground;

[0017] By incorporating ground anchors and spikes, the stability of the support mechanism during use is improved, thus reinforcing and stabilizing the support mechanism, preventing movement, and enhancing the practicality of the device.

[0018] In a preferred embodiment, the two support plates are externally fixedly connected to a plurality of fixing mechanisms, each fixing mechanism including a mounting plate and fixing screws. Each mounting plate is fixedly connected to the outside of the support plate, and each mounting plate is internally threaded with a fixing screw, with the bottom end of each fixing screw extending into the ground.

[0019] By incorporating a fixing mechanism, mounting plate, and fixing screws, the structure is simple and easy to operate, allowing for quick disassembly and fixing, thereby improving the effectiveness of use and enhancing the practicality of the device.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-3 A hydraulic tunnel excavation support structure includes a tunnel 1 and a ground surface 2, with the tunnel 1 located on top of the ground surface 2.

[0029] The tunnel 1 is equipped with a support structure 3, which includes a support frame 31 and two support plates 32. The two support plates 32 are fixedly connected to the support frame 31 and are movably mounted on the ground 2. The support frame 31 is divided into a central area 311 and side areas 312. The central area 311 is located in the middle of the support frame 31, and the side areas 312 are located on both sides of the central area 311. The support thickness of the central area 311 is greater than that of the side areas 312. By setting the central area 311 and the side areas 312, and by increasing the thickness of the central area 311 compared to the side areas 312, the support frame 31 has stronger support force and is less likely to fall apart or collapse due to gravity. This reduces the probability of collapse during excavation and the probability of danger to operators, thereby effectively ensuring the stability of the tunnel.

[0030] The support frame 31 is equipped with a load-bearing mechanism 4, which includes an I-beam 41. The I-beam 41 is fixedly connected to the middle section 311 inside the support frame 31. By setting the load-bearing mechanism 4 and the I-beam 41, the I-beam, a type of steel with an I-shaped cross-section, is called "I-beam" because of its strong ability to withstand pressure and tension. It is mainly made of carbon steel, low alloy steel and high strength steel, and has high strength and rigidity. Its strength and stability can ensure the safety and stability of the structure, thereby improving the practicality of the device.

[0031] The support frame 31 is equipped with a reinforcement mechanism 5, which includes a reinforcement plate 51 and reinforcement bars 52. Both reinforcement plates 51 are located in the side area 312 of the support frame 31, and multiple reinforcement bars 52 are inserted inside the two reinforcement plates 51. By setting up the reinforcement mechanism 5, reinforcement plates 51 and reinforcement bars 52, the rigidity and stability of the support frame 31 are increased, preventing loosening, displacement or deformation during construction, thereby improving the practicality of the device.

[0032] The support frame 31 is provided with a protective mechanism 6 on its exterior. The protective mechanism 6 includes a wear-resistant layer 61 and a waterproof layer 62. The waterproof layer 62 is located on the exterior of the support frame 31, and the wear-resistant layer 61 is located on the exterior of the waterproof layer 62. By setting up the protective mechanism 6, the wear-resistant layer 61 and the waterproof layer 62, the support frame 31 has certain wear resistance and waterproof performance during construction, thereby extending the service life of the support frame 31, ensuring the quality of use of the support frame 31, and thus improving the practicality of the device.

[0033] Both support plates 32 are equipped with a moving mechanism 7 inside. The moving mechanism 7 includes a groove 71 and a moving wheel 72. Each groove 71 is opened inside the support plate 32, and a moving wheel 72 is slidably connected inside each groove 71. The outside of each moving wheel 72 is in contact with the ground 2. By setting the moving mechanism 7, the groove 71 and the moving wheel 72, the mobility and convenience of the support mechanism 3 during use are improved, thereby enhancing the practicality of the device.

[0034] Multiple sets of ground-piercing mechanisms 8 are provided at the bottom of the two support plates 32. The ground-piercing mechanism 8 includes ground spikes 81. Each set of ground spikes 81 is located at the bottom of the support plate 32 and each set of ground spikes 81 is embedded in the ground 2. By setting the ground-piercing mechanism 8 and ground spikes 81, the stability of the support mechanism 3 during use is improved, which is used to strengthen and stabilize the support mechanism 3, prevent movement, and thus improve the practicality of the device.

[0035] Multiple fixing mechanisms 9 are externally fixed to the two support plates 32. Each fixing mechanism 9 includes a mounting plate 91 and fixing screws 92. Each mounting plate 91 is fixedly connected to the outside of the support plate 32, and each mounting plate 91 is internally threaded with a fixing screw 92. The bottom end of each fixing screw 92 extends into the ground 2. By setting the fixing mechanism 9, mounting plate 91 and fixing screw 92, the structure is simple and easy to operate, and it has the effect of quick disassembly and fixing. Thus, the use effect is improved, thereby enhancing the practicality of the device.

[0036] Working principle: By setting up a middle zone 311 and side zones 312, the thickness of the middle zone 311 is greater than that of the side zones 312 on both sides. Therefore, by increasing the central strength of the support frame 31, the support frame 31 has a stronger supporting force and is less likely to fall apart or collapse due to gravity. This reduces the probability of collapse during excavation and the probability of danger to operators, thereby effectively ensuring the stability of the tunnel.

[0037] By setting up the load-bearing mechanism 4 and the I-beam 41, the I-beam is a type of steel with an I-shaped cross section. It is called "I-beam" because of its strong ability to withstand pressure and tension. It is mainly made of carbon steel, low alloy steel and high strength steel, and has high strength and rigidity. Its strength and stability can ensure the safety and stability of the structure.

[0038] By setting up reinforcement mechanism 5, reinforcement plate 51 and reinforcement steel bar 52, the rigidity and stability of support frame 31 are increased, preventing loosening, displacement or deformation during construction.

[0039] By setting up the protective mechanism 6, the wear-resistant layer 61 and the waterproof layer 62, the support frame 31 has certain wear-resistant and waterproof properties during construction, thereby extending the service life of the support frame 31 and ensuring the quality of use of the support frame 31.

[0040] By setting up the moving mechanism 7, the groove 71 and the moving wheel 72, the mobility and convenience of the support mechanism 3 during use are improved.

[0041] By setting up the ground anchoring mechanism 8 and the ground spikes 81, the stability of the support mechanism 3 during use is improved, which is used to strengthen and stabilize the support mechanism 3 and prevent movement.

[0042] By setting up a fixing mechanism 9, a mounting plate 91, and fixing screws 92, the structure is simple and easy to operate, and it has the effect of quick disassembly and fixing, thereby improving the use effect.
