Description
Technical Field
[0001] This application relates to the field of shaft construction, and in particular to a material feeding hole for an ultra-deep water-rich shaft in a railway tunnel. Background Technology
[0002] In order to facilitate the efficient delivery of materials such as concrete to the tunnel construction section during railway tunnel construction, vertical shafts are usually opened above the tunnel to form a vertical channel that is connected to the tunnel construction section, thereby facilitating the efficient delivery of materials such as concrete.
[0003] A vertical shaft feeding hole typically includes a shaft body and a feeding pipe installed inside the shaft body. The top of the feeding pipe is located near the shaft opening, and the bottom of the feeding pipe extends into the railway tunnel. During construction, materials such as concrete can be fed into the feeding pipe and then conveniently and quickly fed into the railway tunnel.
[0004] Regarding the aforementioned technologies, when the shaft is located in a water-rich area with complex geological conditions and a deep excavation depth, although the feeding pipe installed in the shaft can efficiently deliver materials such as concrete into the railway tunnel, the concrete and other materials are prone to causing a large impact on the feeding pipe during the feeding process, which makes it difficult to guarantee the service life of the feeding pipe. Utility Model Content
[0005] In order to facilitate the efficient delivery of materials such as concrete into railway tunnels and to ensure the service life of the feeding pipe, this application provides a feeding hole for an ultra-deep water-rich vertical shaft in a railway tunnel.
[0006] The technical solution provided in this application for a feeding hole in an ultra-deep, water-rich vertical shaft of a railway tunnel adopts the following:
[0007] A feeding hole for an ultra-deep water-rich vertical shaft in a railway tunnel includes a shaft body and a feeding pipe installed inside the shaft body. The feeding pipe includes a conveying pipe and a buffer pipe. The buffer pipe includes a buffer conveying section and a vertical conveying section. One end of the buffer conveying section is connected to the conveying pipe and the other end is connected to the vertical conveying section. The vertical conveying section is arranged parallel to the conveying pipe, and there is an angle between the axis of the buffer conveying section and the axis of the vertical conveying section.
[0008] By adopting the above technical solution, the buffer conveying section of the buffer pipeline plays a buffering role when materials such as concrete are sent into the railway tunnel through the feeding pipe. This helps to reduce the impact of materials such as concrete on the feeding pipe during the feeding process, which helps to ensure the service life of the feeding pipe and thus helps to achieve stable and continuous conveying of materials such as concrete.
[0009] Optionally, multiple conveying pipes and buffer pipes are arranged at intervals along the vertical direction. The top of the vertical conveying section of each buffer pipe is fixedly connected to a conveying extension section. The top of the conveying extension section is fixedly installed with a conveying cover plate that closes its own opening by bolts.
[0010] By adopting the above technical solution, multiple buffer pipes can help achieve multiple buffers when conveying materials such as concrete, thereby further ensuring the service life of the feeding pipe. In addition, after opening the conveying cover, the conveying extension section makes it easy to observe the situation inside the buffer pipe, which is conducive to subsequent inspection, maintenance and adaptive adjustment of the buffer pipe.
[0011] Optionally, the two ends of the conveying pipeline are fixedly connected to a first flange, the end of the buffer conveying section away from the vertical conveying section is fixedly connected to a second flange, and the end of the vertical conveying section away from the buffer conveying section is fixedly connected to a third flange. The two first flanges of the conveying pipeline are respectively fixedly installed to the second flange and the third flange by bolts.
[0012] By adopting the above technical solution, the flange fixing setting makes the operation of fixing the conveying pipeline and the buffer pipeline to each other convenient and stable.
[0013] Optionally, the first flange is fixedly connected to a plurality of positioning pins circumferentially distributed around its own axis, and the second flange and the third flange are both provided with positioning holes circumferentially distributed around their own axes and corresponding to each positioning pin. Each positioning pin is inserted into and engaged with each positioning hole.
[0014] By adopting the above technical solution, the cooperation between the positioning column and the positioning hole plays a positioning role when connecting the conveying pipeline and the buffer pipeline, which facilitates the rapid and stable fixing of the conveying pipeline and the buffer pipeline.
[0015] Optionally, sealing gaskets are fixedly installed between the two first flanges of the conveying pipeline and the second and third flanges, respectively.
[0016] By adopting the above technical solution, the setting of the sealing gasket helps to ensure the sealing performance after the connection between the conveying pipeline and the buffer pipeline, so that moisture or other impurities are not easily seeped into the conveying pipeline through the gap between the conveying pipeline and the buffer pipeline, which helps to ensure the conveying quality of the conveying pipeline.
[0017] Optionally, a discharge pipe is provided near the bottom of the well body, the discharge pipe includes multiple discharge sections, and two adjacent discharge sections are connected by a connecting assembly. The connecting assembly includes a connecting screw, a connecting fixing rod, and a connecting sleeve. Multiple connecting assemblies are distributed circumferentially around the axis of the discharge section. The connecting screw is fixedly installed in one of the discharge sections, the connecting fixing rod is rotatably installed in another adjacent discharge section, and the connecting sleeve is coaxially rotatably installed on the connecting fixing rod. The connecting screw passes through and is threaded into the connecting sleeve.
[0018] By adopting the above technical solution, when one of the connecting sleeves is rotated, the connecting screw drives the discharge pipe to make a slight adjustment in angle and direction, which facilitates the slight adjustment of the position of the bottom opening of the discharge pipe, making it easier for materials such as concrete to fall into different positions in the well body, and making it highly applicable.
[0019] Optionally, the radial dimension of the opening at the top of the discharge section is smaller than the radial dimension of the opening at the bottom of the discharge section.
[0020] By adopting the above technical solution, when materials such as concrete are discharged through the discharge pipe, the material between two adjacent discharge sections is less likely to fall out of the discharge pipe, which helps to further ensure the stability of the feeding and conveying of materials such as concrete.
[0021] Optionally, a feed hopper is fixedly connected to the top of the conveying pipe near the top of the well body, and the radial dimension of the feed hopper away from the conveying pipe is smaller than the radial dimension of the feed hopper near the conveying pipe.
[0022] By adopting the above technical solution, the feeding hopper is designed to facilitate rapid filling of materials during feeding, allowing the materials to enter the conveying pipeline more smoothly.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The buffer conveying section serves to buffer the flow of materials such as concrete into the railway tunnel through the feeding pipe. This helps to reduce the impact of the materials on the feeding pipe during the feeding process, thus ensuring the service life of the feeding pipe and facilitating the continuous and stable conveying of materials such as concrete.
[0025] 2. The installation of sealing gaskets helps to ensure the sealing of the connection between the conveying pipeline and the buffer pipeline, so that moisture or other impurities are not easily seeped into the conveying pipeline through the gap between the conveying pipeline and the buffer pipeline, which helps to ensure the conveying quality of the conveying pipeline.
[0026] 3. When one of the connecting sleeves is rotated, the connecting screw drives the discharge pipe to make a slight adjustment in angle and direction, which facilitates the slight adjustment of the position of the bottom opening of the discharge pipe, making it easier for materials such as concrete to fall into different positions in the well body, and making it highly applicable.

[0033] The following is combined with Figure 1-4 This application is described in further detail.
[0034] This application discloses a material feeding hole for an ultra-deep, water-rich vertical shaft in a railway tunnel. (Refer to...) Figure 1 The feeding hole of the ultra-deep water-rich vertical shaft of the railway tunnel includes a shaft body 1 and a feeding pipe 2 set in the shaft body 1. Specifically, the feeding pipe 2 includes a conveying pipe 201 and a buffer pipe 202. The conveying pipe 201 and the buffer pipe 202 are both set in the shaft body 1 and are arranged at intervals along the vertical direction.
[0035] The buffer pipe 202 includes a buffer conveying section 2021 and a vertical conveying section 2022. One end of the buffer conveying section 2021 is connected to and installed in the conveying pipe 201, and the other end is integrally connected to and installed in the vertical conveying section 2022. The conveying pipe 201 is a straight pipe. The axis of the vertical conveying section 2022 is parallel to the axis of the conveying pipe 201. There is an angle between the axis of the buffer conveying section 2021 and the axis of the vertical conveying section 2022. The angle between the axis of the buffer conveying section 2021 and the axis of the vertical conveying section 2022 is greater than 0 degrees and less than or equal to 60 degrees. In this embodiment, the angle between the axis of the buffer conveying section 2021 and the axis of the vertical conveying section 2022 is set to 45 degrees so that the buffer conveying section 2021 can play a stable buffering role in the conveying of materials in the buffer pipe 202.
[0036] To facilitate a direct observation of the material conveying process within the vertical conveying section 2022, each buffer pipe 202 has an integrally fixed and connected conveying extension section 3 at the top of its vertical conveying section 2022. The top of the conveying extension section 3 is bolted with a conveying cover plate 4 that closes its own opening. When the conveying cover plate 4 is opened, it is convenient to observe the conveying process within the vertical conveying section 2022 directly through the opening of the conveying extension section 3.
[0037] Both ends of the conveying pipe 201 are fixedly connected to a first flange 5. The end of the buffer conveying section 2021 away from the vertical conveying section 2022 is fixedly connected to a second flange 6. The end of the vertical conveying section 2022 away from the buffer conveying section 2021 is fixedly connected to a third flange 7. The two first flanges 5 of the conveying pipe 201 are respectively fixedly installed to the second flange 6 and the third flange 7 by bolts, so as to quickly and stably achieve a secure connection between the conveying pipe 201 and the buffer pipe 202.
[0038] To ensure the stability of the position when the conveying pipe 201 and the buffer pipe 202 are connected, the first flange 5 is fixedly connected with a plurality of positioning pins 8 evenly distributed around its own axis. The second flange 6 and the third flange 7 are both provided with positioning holes 9 distributed around their own axes and corresponding one-to-one with each positioning pin 8. Each positioning pin 8 is inserted into and fitted with each positioning hole 9 to provide positioning for the connection of the conveying pipe 201 and the buffer pipe 202.
[0039] On the side of the first flange 5 away from the conveying pipe 201, a sealing gasket 10 is fixedly installed by adhesive bonding. Each positioning post 8 passes through the sealing gasket 10. In this embodiment, the sealing gasket 10 is made of rubber. When the conveying pipe 201 and the buffer pipe 202 are connected, the sealing gasket 10 presses against the second flange 6 or the third flange 7 to further ensure the waterproof sealing after the connection between the conveying pipe 201 and the buffer pipe 202.
[0040] A feed hopper 11 is fixedly connected to the top of the conveying pipe 201 near the top of the well body 1. The radial dimension of the opening of the feed hopper 11 away from the conveying pipe 201 is smaller than the radial dimension of the feed hopper 11 near the conveying pipe 201, so as to facilitate rapid filling when the material is fed, so that the material can enter the conveying pipe 201 more smoothly.
[0041] A discharge pipe 12 is coaxially fixed at the bottom of the conveying pipe 201 near the bottom of the well body 1. Specifically, the discharge pipe 12 includes multiple discharge sections 121. In this embodiment, the number of discharge sections 121 is four. Adjacent discharge sections 121 are connected by connecting components. There are two connecting components distributed circumferentially around the axis of the discharge section 121, and two vertically adjacent connecting components are located at different positions of the discharge section 121.
[0042] In this embodiment, two adjacent discharge sections 121 are designated as follows: the discharge section 121 at the bottom is the first discharge section 121, and the discharge section 121 at the top is the second discharge section 121. The connecting assembly includes a connecting screw 13, a connecting fixing rod 14, and a connecting sleeve 15. The connecting screw 13 is fixedly installed in the first discharge section 121, the connecting fixing rod 14 is rotatably installed in the adjacent second discharge section 121, and the connecting sleeve 15 is coaxially rotatably installed on the connecting fixing rod 14. The connecting screw 13 passes through and is threaded into the connecting sleeve 15, so that when one of the connecting sleeves 15 is rotated, the connecting screw 13 moves towards the connecting sleeve 15, thereby causing the discharge pipe 12 to make minor adjustments to its angle and direction. This facilitates the final falling of materials such as concrete into different positions within the well body 1 through the discharge pipe 12, making it highly adaptable. The discharge sections 121 are all funnel-shaped, that is, the radial dimension of the opening at the top of the discharge section 121 is smaller than the radial dimension of the opening at the bottom of the discharge section 121, so that concrete and other materials are not easily spilled out of the discharge pipe 12 when they are transported through the discharge pipe 12, which facilitates the stability of concrete and other materials when they are fed and transported through the discharge pipe 12.
[0043] The implementation principle of the feeding hole of the ultra-deep water-rich vertical shaft of the railway tunnel in this application embodiment is as follows: During the transportation of materials such as concrete, the buffer transportation section 2021 of the buffer pipe 202 plays a buffering role when the concrete and other materials are sent into the railway tunnel through the feeding pipe 2, thereby helping to reduce the impact of the concrete and other materials on the feeding pipe 2 during the feeding process, making it easier to ensure the service life of the feeding pipe 2, and thus helping to achieve stable transportation of concrete and other materials continuously and stably.
[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
