Abstract

This invention discloses a comprehensive production system and method for a steep inclined shaft in a hydraulic tunnel. The system includes: a crushed stone transportation system for processing excavated stone from the tunnel face into crushed stone and transporting it outside the tunnel; a tunnel water diversion and utilization system for collecting and diverting seepage water from fissures inside the tunnel to an external reservoir, where it is settled and clarified before being used in a sand washing machine; a concrete mixing system for transporting dry-mixed materials produced by an external batching machine to an internal mixing plant via a belt conveyor, where water is added and mixed to produce concrete; and a mine car transportation system for transporting materials and personnel. The required support foundation is simple and easy to install, with low cost, and high utilization of the inclined shaft's clearance. The four transportation systems operate independently and simultaneously, significantly improving transportation efficiency, reducing the frequency of mine car transportation, and greatly enhancing safety. Because the wet mixing process of concrete is moved inside the tunnel, the problem of low efficiency in transporting wet-mixed concrete is solved, significantly improving the production efficiency and utilization rate of concrete construction.

Description

Technical Field

[0001] This invention relates to the field of water conservancy tunnel technology, specifically to a comprehensive production system and method for steep inclined shafts in water conservancy tunnels. Background Technology

[0002] Hydraulic tunnels are tunnels used for water diversion or discharge. They are an important component of water conservancy projects. The tunnel route must be adapted to the construction tasks of the water conservancy project and must be selected based on topography, engineering geology, hydrogeology, and hydrological conditions. According to their function, they are classified as follows: water diversion and conveyance tunnels, used for diverting or conveying water for power generation, irrigation, or industrial and domestic use; diversion and flood discharge tunnels, used for diverting water during construction or discharging floodwater during operation; tailrace tunnels, used to discharge tailwater from hydroelectric power stations; and sediment flushing tunnels, used to flush silt accumulated in reservoirs or to empty reservoirs for air defense or maintenance of hydraulic structures.

[0003] Water conservancy tunnels should be as short and straight as possible. The inclined shafts of water conservancy tunnels generally have a large gradient. They usually use shuttle rail mine cars for up and down transportation. However, due to the limited capacity of the buckets and the slow round trip, the transportation time is long and the efficiency is extremely low, which seriously affects the effectiveness. As the only means of transportation, it is very easy to cause safety accidents, which has become a bottleneck in tunnel construction and seriously affects the efficiency of water conservancy tunnel construction. Summary of the Invention

[0004] To address the problems existing in the prior art, a comprehensive production system and method for steep inclined shafts in hydraulic tunnels is provided.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] This invention proposes an integrated production system for steep inclined shafts in hydraulic tunnels, comprising:

[0007] The crushed stone transportation system is used to process the stone debris excavated from the working face into crushed stone and transport it outside the tunnel, thus completing the processes of slag removal and crushed stone production.

[0008] The tunnel water diversion and utilization system is used to collect and divert seepage water and construction wastewater from the fissures inside the tunnel to a water storage tank outside the tunnel. After sedimentation and clarification, the water is used for sand washing and concrete production.

[0009] A concrete mixing system is used to transport the dry-mixed material produced by the batching machine outside the tunnel to the mixing machine inside the tunnel via a belt conveyor, and then mix it with water to produce concrete.

[0010] A mining car transportation system, which is used to transport materials and personnel.

[0011] Preferably, the crushed stone transportation system includes a jaw crusher, a screening and traction system, and a sand washing machine. The jaw crusher is connected to the screening and traction system via a jaw crusher belt conveyor and the crushed stone transportation system 5. The crushed stone transportation system 5 is located in the inclined shaft section, the jaw crusher belt conveyor and the jaw crusher are located in the main tunnel section, and the screening and traction system and the sand washing machine are located outside the tunnel.

[0012] Preferably, the tunnel water diversion and utilization system includes a mobile water collection tank, a water storage tank, and a sedimentation tank. The water storage tank and the sedimentation tank are located outside the tunnel, and the mobile water collection tank is located in the main tunnel section.

[0013] Preferably, the concrete mixing system includes a mixer and a batching system. The mixer is connected to the batching system through a dry material transportation system. The batching system is located outside the tunnel, the dry material transportation system is located in the inclined shaft section, and the mixer is located in the main tunnel section.

[0014] Preferably, the mine car transportation system includes inclined shaft mine cars, which are installed in the inclined shaft section.

[0015] This invention also proposes a comprehensive production method for steep inclined shafts in hydraulic tunnels, employing the aforementioned comprehensive production system for steep inclined shafts in hydraulic tunnels, comprising the following steps:

[0016] S1: Excavate a slag storage chamber at a specified distance from the working face and perform initial support;

[0017] S2: Install a water diversion and utilization system inside the tunnel, install inclined shaft mine cars, crushed stone transportation system and dry mixing material transportation system in the inclined shaft section, install jaw crusher, jaw crusher belt conveyor and mixer in the main tunnel section, excavate water storage tank and sedimentation tank outside the tunnel, and install screening traction system and sand washing machine.

[0018] S3: During the tunnel excavation process, the fissure water at the tunnel face is diverted to a reservoir outside the tunnel, and then clarified through a sedimentation tank for sand washing. The wastewater after sand washing is then filtered and used to produce concrete.

[0019] S4: Transport the excavated stone debris from the working face to the storage chamber, and feed the jaw crusher with a loader to process the crushed stone;

[0020] S5: The produced crushed stone mixture is conveyed to the screening and traction system by the jaw crusher belt conveyor and crushed stone transportation system. After washing, screening and stacking according to specifications, it forms sand and gravel stacks. The wastewater generated by washing is discharged into natural water bodies after being treated in the sedimentation tank. The sludge adhering to the belt is cleaned with a sludge scraper.

[0021] S6: Use inclined shaft mine cars to transport materials and tools needed for daily construction;

[0022] S7: Use a dry mix transportation system to transport dry mix material into the tunnel. After entering the tunnel, use a mixer to add water and mix it before putting it into use.

[0023] S8: After the construction task is completed, dismantle the crushed stone transportation system, the tunnel water diversion and utilization system, the concrete mixing system and the mine car transportation system. For the slag storage chamber, construct a secondary lining for the slag storage chamber to use it as a functional chamber, or backfill the slag storage chamber with rubble concrete and then construct the main tunnel lining.

[0024] Preferably, before the inclined shaft is excavated, a water diversion and utilization system is built inside the tunnel to pump the accumulated water at the working face of the inclined shaft to a water storage tank outside the tunnel for sedimentation and filtration. During this stage, the water in the water storage tank is used for concrete curing and dust suppression at the construction site. The water inside the tunnel is transported through water pipes, and a flexible hose is used at the downstream end to ensure that the water pump can be moved easily.

[0025] Preferably, after the inclined shaft is excavated and supported to a specified length, the mine car transportation system is built. In the early stage of the inclined shaft excavation, the mine car transportation system is used for transportation inside and outside the tunnel.

[0026] Preferably, after the inclined shaft is excavated, the main tunnel is excavated. After the main tunnel has been advanced to a specified length, the slag storage chamber is excavated, and a concrete mixing system and a crushed stone transportation system are installed, and the water diversion and utilization system inside the tunnel is improved.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. In this invention, a jaw crusher can be used to process larger stone chips, saving the step of breaking smaller chips with explosives / blasting hammers. This provides a working face for drilling and blasting operations in a timely manner. The slag storage chamber is used to temporarily store stone chips, storing raw materials for the jaw crusher's production and ensuring the continuity of stone crushing. In addition, the completed slag storage chamber can be converted into a functional chamber or backfilled. Furthermore, the produced crushed stone and manufactured sand are screened, washed, and stacked according to specifications after exiting the chamber. They can be used to build access roads, or, after passing inspection, used in physical projects or sold externally, thereby improving material utilization efficiency and saving costs.

[0029] 2. This invention comprises three belt conveyor systems. Compared to the mine car transport system, the belt conveyor requires a simple and easy-to-install support foundation, is low in cost, and makes more efficient use of the inclined shaft clearance. The three belt conveyor systems are independent of each other and can operate simultaneously, which greatly improves the transport efficiency and the overall efficiency of tunnel construction, reduces the frequency of use of the mine car transport system, and greatly improves safety.

[0030] 3. This invention utilizes wastewater by diverting fissure water inside the tunnel to a reservoir at the tunnel entrance for sand washing, thereby transferring the wet mixing process of concrete inside the tunnel. This solves the problem of low transportation efficiency of wet-mixed concrete and significantly improves the production efficiency and utilization rate of concrete construction.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figure 1-4 As shown in the figure, this embodiment proposes a comprehensive production system for a steep inclined shaft in a hydraulic tunnel, including a crushed stone transportation system 5. The crushed stone transportation system 5 is used to process the excavated rock slag from the working face into crushed stone and transport it outside the tunnel, completing the processes of slag removal and crushed stone production. The working face, also known as the tunnel face, is a term in tunnel construction. It refers to the working face that is continuously advanced during tunnel excavation (in coal mining, mining, or tunnel engineering).

[0040] The crushed stone transportation system 5 includes a jaw crusher 3, a screening and traction system 6, and a sand washing machine 7. The jaw crusher 3 is connected to the screening and traction system 6 through the jaw crusher belt conveyor 4 and the crushed stone transportation system 5. The crushed stone transportation system 5 is located in the inclined shaft section, the jaw crusher belt conveyor 4 and the jaw crusher are located in the main tunnel section, and the screening and traction system 6 and the sand washing machine 7 are located outside the tunnel.

[0041] The crushed stone transport system 5 transports the excavated stone debris from the working face to the slag storage chamber, completing the slag removal process. The jaw crusher 3 crushes the stone debris with extremely irregular particle size and shape, and the crushed stone is sent out of the tunnel via the jaw crusher belt conveyor 4 and the crushed stone transport system 5. After screening, washing, and inspection, the crushed stone is used internally or sold.

[0042] Jaw crusher 3 processes larger stone chips, saving the step of breaking smaller ones with explosives / blasting hammers, and promptly providing a working face for drilling and blasting operations. The slag storage chamber is used to temporarily store stone chips, storing raw materials for the production of jaw crusher 3 and ensuring the continuity of stone crushing.

[0043] In addition, the completed slag storage cavern can be converted into a functional cavern or used for backfilling. The crushed stone and manufactured sand produced can be screened, washed, and stacked according to specifications after leaving the cavern. They can be used to build access roads, or used in physical projects or sold after passing inspection, thereby improving material utilization efficiency and saving costs.

[0044] The tunnel water diversion and utilization system 13 is used to collect and divert seepage water and construction wastewater from the cracks in the tunnel to a water storage tank outside the tunnel. After sedimentation and clarification, the water is used by the sand washing machine 7 to produce concrete.

[0045] The tunnel water diversion and utilization system 13 includes a mobile water collection tank 2, a water storage tank and a sedimentation tank 14. The water storage tank and sedimentation tank 14 are located outside the tunnel, while the mobile water collection tank 2 is located in the main tunnel section. The mobile water collection tank 2 is used for water collection inside the tunnel.

[0046] The tunnel water diversion and utilization system 13 collects and diverts seepage water from the fissures inside the tunnel to a reservoir outside the tunnel. After sedimentation and clarification, the water is used in the sand washing machine 7. The wastewater generated from sand washing is filtered through a three-stage sedimentation tank before being discharged into natural water bodies, thus achieving the effects of wastewater utilization and environmental protection.

[0047] The concrete mixing system 15 is used to transport the dry-mixed material produced by the batching machine 12 outside the tunnel to the mixing machine 12 inside the tunnel via a belt conveyor, add water and mix to produce concrete for construction inside the tunnel.

[0048] The concrete mixing system 15 includes a mixer 12 and a batching system 10. The mixer 12 is connected to the batching system 10 through a dry material transport system 11. The batching system 10 is located outside the tunnel, the dry material transport system 11 is located in the inclined shaft section, and the mixer 12 is located in the main tunnel section.

[0049] The concrete mixing system 15 solves the problem of low transportation efficiency of wet-mixed concrete by transferring the wet mixing process of concrete to the tunnel, and significantly improves the production efficiency and utilization rate of concrete construction.

[0050] The mine car transportation system 8 is used to transport materials and personnel. The mine car transportation system 8 includes inclined shaft mine cars 9, which are located in the inclined shaft section. The mine car transportation system 8 meets the transportation needs of personnel, reinforcing bars, structural steel, machinery, parts, etc.

[0051] The three belt conveyor systems include a crushed stone transport system 5 (upward), an inclined shaft mine car 9 (double-track), and a dry material transport system 11 (downward). Compared to the mine car transport system, the crushed stone transport system 5, the inclined shaft mine car 9, and the dry material transport system 11 all use belt conveyors. The support foundation required for belt conveyors is simple and easy to install, with low cost, and makes more efficient use of the inclined shaft clearance. The three belt conveyor systems are independent of each other and can operate simultaneously, which greatly improves transport efficiency, reduces the frequency of use of the mine car transport system, and greatly improves safety.

[0052] This invention also proposes a comprehensive production method for steep inclined shafts in hydraulic tunnels, employing the comprehensive production system for steep inclined shafts in hydraulic tunnels described in this embodiment, including the following steps:

[0053] S1: Excavate a slag storage chamber at a specified length away from the working face and perform initial support. The specified length refers to a position that is safe enough from the working face.

[0054] S2: Install the tunnel water diversion and utilization system 13, install the inclined shaft mine car 9, the crushed stone transportation system 5, and the dry mixing material transportation system 11 in the inclined shaft section, install the jaw crusher 3, the jaw crusher belt conveyor 4 and the mixer 12 in the main tunnel section, excavate the water storage tank and sedimentation tank 14 outside the tunnel, and install the screening traction system 6 and the sand washing machine 7 as well as other necessary corresponding equipment.

[0055] S3: During the tunnel excavation process, the fissure water at the tunnel face is diverted to a reservoir outside the tunnel, and then settled and clarified in sedimentation tank 14 for sand washing. The wastewater after sand washing is discharged into natural water bodies or used to produce concrete, achieving the effects of wastewater utilization and environmental protection.

[0056] S4: Transport the excavated stone debris from the working face to the storage chamber, and feed it to the jaw crusher 3 via a loader to process the crushed stone;

[0057] S5: The produced crushed stone mixture is conveyed to the screening traction system 6 via the jaw crusher belt conveyor 4 and the crushed stone transportation system 5. The screening traction system 6 includes a screening machine. After washing, screening, and stacking according to specifications, the sand and gravel stack 1 is formed. The wastewater generated by washing is treated in the sedimentation tank 14 and then discharged into the natural water body. The sludge adhering to the belt is cleaned with a sludge scraper.

[0058] S6: Use inclined shaft mine cars 9 to transport materials such as steel bars and structural steel, as well as equipment, parts and other tools required for daily construction.

[0059] S7: Use the dry mix transportation system 11 to transport the dry mix into the tunnel. After entering the tunnel, use the mixer 12 to add water and mix it before putting it into use.

[0060] S8: After the construction task is completed, dismantle the crushed stone transportation system 5, the tunnel water diversion and utilization system 13, the concrete mixing system 15 and the mine car transportation system 8. For the slag storage chamber, construct a secondary lining for the slag storage chamber to use it as a functional chamber, or backfill the slag storage chamber with rubble concrete and then construct the main tunnel lining.

[0061] Before the inclined shaft is excavated, a water diversion and utilization system 13 is built inside the tunnel to pump the accumulated water at the working face of the inclined shaft to a water storage tank outside the tunnel for sedimentation and filtration.

[0062] During this phase, other systems were not yet completed. The water in the reservoir was used for concrete curing and dust suppression at the construction site. Water inside the tunnel was transported through pipes, which were primarily constructed using support-mounted steel pipes to ensure stability, while flexible hoses were used at the downstream end to facilitate pump movement.

[0063] After the inclined shaft is excavated and supported to a specified length, the mine car transportation system 8 is constructed. In the early stages of the inclined shaft excavation, the mine car transportation system 8 is used for transportation inside and outside the shaft. The mine car transportation system includes the foundation, supports, and tracks inside the shaft, as well as the foundation, supports, portal, and traction machine of the external traction unit.

[0064] Initially, the mine car transportation system 8 was mainly used for transportation inside and outside the tunnel. The components of the inclined shaft mine car 9 should be at least 50m away from the working face to avoid damage to the components caused by flying rocks from blasting at the working face.

[0065] The ground beneath the mine car support foundation should be leveled (or reinforced with rebar as an anti-slip measure) to ensure vertical load-bearing capacity and prevent slippage caused by frequent vibrations during use. The bedrock surface must be thoroughly cleaned before pouring the foundation concrete.

[0066] Supports, tracks, and other components must be securely installed and positioned close to the central axis of the inclined shaft, providing sufficient space for the crushed stone conveyor and dry-mix material conveyor. A passageway should be provided outside the tunnel for vehicles to ensure road access.

[0067] After the inclined shaft is excavated, the main tunnel is excavated. After the main tunnel advance exceeds the specified length, the slag storage chamber is excavated, and the concrete mixing system 15 and the crushed stone transportation system 5 are installed. The water diversion and utilization system 13 inside the tunnel is also improved.

[0068] The components of each system should be at least 50m away from the working face to avoid damage to the components caused by flying rocks from blasting at the working face. The belt conveyors of the concrete mixing system 15 and the crushed stone transportation system 5 need to be equipped with scrapers to remove the debris adhering to the belt conveyors, and the residual material spilled under the belts should be cleaned up regularly to ensure transmission efficiency.

[0069] When selecting the model of jaw crusher 3, it is necessary to comprehensively consider factors such as the cross-section of the main tunnel, the excavation progress, the lithology and grade of the surrounding rock. It is recommended to select a slightly higher specification to ensure that the tunnel muck can be consumed in a timely manner.

[0070] Due to the limited clearance inside the tunnel, the mixing machine 12 adopts a low support form, and small tank trucks are used for the transportation of shotcrete and lining concrete inside the tunnel.

[0071] In addition, the screening machine and sand washing machine outside the tunnel need to be cleaned regularly to remove any adhering or spilled gravel to ensure continuous production.

[0072] All equipment inside and outside the tunnel requires a stable and large power supply. Each piece of equipment needs to be equipped with an independent power distribution system and corresponding fire-fighting equipment, especially the jaw crusher 3 and the mixing machine 12 inside the tunnel.

[0073] The various sizes of sand and gravel produced by the crushed stone transportation system 5 can be used in the concrete mixing system 15, and the excess sand and gravel can be sold externally.

[0074] The tunnel water diversion and utilization system 13 collects water from inside the tunnel into a reservoir outside the tunnel. The water in the reservoir can be used for concrete mixing system 15 after sedimentation and filtration, while excess water can be discharged into natural water bodies after three-stage sedimentation and filtration.

[0075] The mining car transportation system 8 is used for the transportation of personnel, steel, machinery, etc., including the transportation of various materials and tools.

[0076] The concrete mixing system 15 can use the sand and gravel produced by the crushed stone transportation system 5 and the water produced by the tunnel water diversion and utilization system 13 to produce concrete in the tunnel mixing machine 12. The concrete is used for initial support concrete, lining concrete, etc., and is applied to tunnel excavation and lining. During the tunnel excavation process, the surrounding rock fissure water, drilling wastewater, curing wastewater, etc. can be collected by the tunnel water diversion and utilization system 13 and sent to the water storage tank outside the tunnel. The tunnel slag produced can be processed by the jaw crusher 3 to produce sand and gravel of various specifications.

[0077] The four systems described above work together to significantly improve production efficiency and quality, enhance material utilization, and fully utilize wastewater and waste generated during production, effectively saving production costs. The three belt conveyor systems are simple to install, low in cost, and make more efficient use of the inclined shaft clearance. Furthermore, the three belt systems operate independently and simultaneously, greatly improving transportation efficiency and significantly enhancing safety.

[0078] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
