Description

Technical Field

[0001] The present invention relates to the technical field of concrete assembly, and particularly to a hydraulic concrete lining structure that can be quickly assembled. Background Art

[0002] The precast concrete tunnel lining structure is a tunnel support system formed by prefabricating concrete components such as arch rings, side walls, and invert arches in a factory and mechanically assembling them on site. This structure transfers the processes of concrete pouring, curing, and formwork removal in traditional in-situ construction to the factory, uses standardized molds to produce high-precision components, transports them to the site for rapid assembly, and realizes the integrity and waterproof performance of the structure through joint treatment technology.

[0003] According to the tunnel design drawings, geological exploration reports, and relevant specifications, a detailed precast lining construction plan is formulated. Precast concrete lining components are prefabricated in the factory according to the design requirements. Cranes, transport vehicles, assembly equipment, surveying instruments, etc. are prepared to ensure that the equipment performance is good and meets the construction requirements. After the tunnel excavation and initial support construction are completed, the precast components are transported from the factory to the construction site by special transport vehicles. A temporary storage area is set up at the tunnel entrance or a designated site, and the precast components are stored separately. A cushion layer is laid at the bottom of the tunnel, and the installation position of the invert arch is determined by measuring and setting out. The precast invert arch component is hoisted to the design position by a crane, and the elevation and flatness of the component are adjusted. The side wall components are hoisted in sequence and connected to the invert arch and adjacent side wall components through embedded connectors. Support frames are set on the side walls, and the arch ring components are installed to the design position by means of segmented hoisting or integral hoisting.

[0004] However, traditional in-situ cast concrete lining requires on-site formwork support, pouring, and curing. The construction of a single ring takes a long time. The in-situ casting process needs to be carried out layer by layer and cannot be carried out in parallel. On-site pouring and curing are required, resulting in a long construction period and low efficiency. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0027] Embodiment 1

[0028] Referring to Figures 1 - 4 , which is the first embodiment of the present invention, a quickly assembled hydraulic concrete lining structure is provided, including a bottom plate 1. A plurality of main bodies 2 are fixedly connected to the top end of the bottom plate 1. A first support ring 4 is fixedly connected to the inner wall of the main body 2. A through hole for the sliding of a cylinder 13 is formed in the outer wall of the first support ring 4. A sealing gasket 11 is fixedly connected to the outer wall of the first support ring 4. The sealing gasket 11 is elastic. A second support ring 9 fixedly connected to the inner wall of the main body 2 is movably connected to the outer wall of the sealing gasket 11. Two drain pipes 5 distributed in a mirror image are fixedly connected to the inner wall of the main body 2. The drain pipes 5 are used to guide water flow into a drain port 6. A diversion pipe 10 slidably connected to the inner wall of the main body 2 is formed in the inner wall of the drain pipe 5. A plurality of cylinders 13 clamped to the inner wall of the second support ring 9 are slidably connected to the inner wall of the first support ring 4. The cylinders 13 are used to fix the first support ring 4 and the second support ring 9.

[0029] Two sliding blocks 14 distributed in a mirror image are fixedly connected to the outer wall of the cylinder 13. The sliding blocks 14 are used to position the angle of insertion of the cylinder 13. A convex plate fitting the outer wall of the first support ring 4 is fixedly connected to the outer wall of the cylinder 13. A push rod 12 is slidably connected to the inner wall of the cylinder 13. The push rod 12 is used to push a trapezoidal block 18.

[0030] Two baffles 15 distributed in a mirror image are fixedly connected to the outer wall of the push rod 12. Two movable plates 17 corresponding to the baffles 15 are slidably connected to the inner wall of the cylinder 13. A first spring 16 is connected between the outer wall of the movable plate 17 and the inner wall of the baffle 15. The first spring 16 is used to push the baffle 15. A moving groove for the movement of the baffle 15 is formed in the inner wall of the cylinder 13. The moving groove is in an "L" shape.

[0031] Two trapezoidal blocks 18 distributed in a mirror image are slidably connected to the inner wall of the cylinder 13. Two second springs 19 distributed in a mirror image are connected between the outer wall of the trapezoidal block 18 and the inner wall of the cylinder 13. The second springs 19 are used to push the trapezoidal block 18 into a notch. A notch for the sliding of the second spring 19 is formed in the outer wall of the second support ring 9.

[0032] During use, the main body 2 drives the sealing gasket 11 to be inserted into the outer wall of the second support ring 9 through the first support ring 4, and the cylinder 13 is inserted along the through hole of the first support ring 4. The cylinder 13 enters the inner wall of the second support ring 9 through the sliding block 14. When the convex plate contacts the outer wall of the first support ring 4, the push rod 12 is pushed to squeeze the first spring 16 through the baffle 15. At the same time, the push rod 12 squeezes the outer wall of the trapezoidal block 18. Since the contact surface between the trapezoidal block 18 and the push rod 12 is an inclined surface, the trapezoidal block 18 is forced to squeeze the second spring 19, and the trapezoidal block 18 enters the groove. At this time, the push rod 12 is rotated to drive the baffle 15 and the movable plate 17 to rotate, and then the limit is achieved.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a guide port 3 is provided at the top of the main body 2 to facilitate the sliding of the outer wall of the guide pipe 10. Two mirror-distributed sealing rings 21 are fixedly connected to the inner wall of the guide port 3. The sealing ring 21 is used to limit the permeable geotextile 20. A permeable geotextile 20 is installed between the two sealing rings 21. The permeable geotextile 20 is used to prevent sand from entering the guide pipe 10, while not affecting the water entering the guide pipe 10 through the permeable geotextile 20.

[0035] One end of the outer wall of the drain pipe 5 is fixedly connected to a plurality of positioning rods 7 distributed in a circular array. The positioning rods 7 facilitate the installation of multiple main bodies 2. The other end of the drain pipe 5 is provided with a circular groove for facilitating the sliding of the positioning rods 7. Both ends of the outer wall of the drain pipe 5 are fixedly connected to a magnet ring 8. The bottom end of the base plate 1 is provided with a drain outlet 6 connected to the inner wall of the drain pipe 5. The drain outlet 6 is used to discharge water to avoid accumulation.

[0036] During use, when the main body 2 is installed in sequence, the positioning rod 7 of the drain pipe 5 is aligned with the circular groove of the other drain pipe 5 and inserted, and at the same time, the two magnet rings 8 are adsorbed and fitted, and the water flows into the diversion port 3 from the top of the main body 2, and the water flows into the diversion pipe 10 through the permeable geotextile 20, and the water flows into the inner wall of the drain pipe 5 through the diversion pipe 10, and the water flows into the drain port 6 through the drain pipe 5 and is discharged, and the operation is completed.
