Description

Technical Field

[0001] This utility model relates to the field of underground spring sealing technology, specifically a composite structure for sealing underground springs. Background Technology

[0002] Groundwater gushing refers to the concentrated discharge or sudden surge of groundwater that exists in the pores or fissures of underground rock strata or soil, driven by water pressure difference, gravity, or geological structure, breaking through the water-impermeable boundary of the strata or natural / artificial channels to the surface or underground engineering space. Its essence is the fluid migration process under the coupling effect of groundwater and geological media.

[0003] An investigation revealed that a Chinese utility model patent, CN222207862U, discloses a structure for sealing underground water inflow boreholes. The structure includes a drainage pipe installed within the borehole, a sealing plate fixedly fitted onto the drainage pipe, and the sealing plate sealingly abutting against the inner wall of the borehole. A reinforcing column extending outward from the sealing plate to strengthen the structure is also present. Grout is filled between the borehole, the sealing plate, and the reinforcing column. The structural design of the drainage pipe, sealing plate, and reinforcing column makes the sealing structure more robust and stable, improving the sealing effect, preventing the spread of underground water inflow, and protecting the safety of the project.

[0004] When users use the aforementioned patents, existing devices struggle to achieve precise matching and efficient sealing in the face of springs with varying pressures and flow rates. Furthermore, they lack tiered pressure reduction and multi-layered protection designs. When faced with high-pressure, strong water inrush, a single sealing layer is insufficient to withstand the continuous impact of water flow. After prolonged use, structural deformation can easily occur, leading to sealing failure and a decrease in sealing effectiveness. Consequently, these devices cannot meet the long-term stable sealing requirements of complex engineering scenarios.

[0005] Therefore, this utility model provides a composite structure for sealing underground springs to solve the above-mentioned problems. Utility Model Content

The bearing shell is installed and connected inside the protective component. The mesh is fixedly connected to the inner side of the bearing shell. The fixing plate is fixedly connected to one side of the mesh. The anchors are evenly distributed along the circumference of the bearing shell and penetrate the bearing shell and extend outward. The first handle is fixedly connected to one side of the bearing shell.

[0013] Beneficial effects: This utility model, by setting up a pressure-reducing component consisting of a pressure-reducing shell, permeable gravel, and chemical grouting, allows for flexible adjustment of the installation parameters and material ratios of each component according to different water inflow pressures and flow rates. The amount of permeable gravel filling can be dynamically adjusted according to the water inflow. The inflowing water first passes through the permeable gravel layer for initial diversion and buffering, reducing the impact intensity of the water flow. Then, it completes secondary interception through a tight sealing layer formed by chemical grouting, constructing a graded pressure-reducing and sealing system.

It significantly improves the impact resistance and long-term stability of the structure under high-pressure and strong water inflow scenarios, extends the service life of the sealing structure, and meets the user's operational needs.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1-5 The present invention provides a technical solution: a composite structure for sealing underground springs, comprising a protective component 1, a load-bearing component 2, a sealing component 3, and a pressure-reducing component 4. The load-bearing component 2 is installed and connected inside the protective component 1, the sealing component 3 is installed and connected below the load-bearing component 2, and the pressure-reducing component 4 is installed and connected below the sealing component 3. The pressure-reducing assembly 4 includes a pressure-reducing shell 41, a chemical grouting 42, a permeable gravel 43, and a third handle 44. The pressure-reducing shell 41 is installed inside the protective assembly 1, the chemical grouting 42 is fixedly connected inside the pressure-reducing shell 41, the permeable gravel 43 is fixedly connected to one side of the chemical grouting 42, and the third handle 44 is fixedly connected to the outside of the pressure-reducing shell 41. In this embodiment, a pressure-reducing assembly consisting of a pressure-reducing shell 41, permeable gravel 43, and chemical grouting 42 is set up. The installation parameters and material ratios of each component can be flexibly adjusted according to different water inflow pressures and flow rates. The filling amount of permeable gravel 43 can be dynamically adjusted according to the water inflow. The water inflow first passes through the permeable gravel 43 layer to achieve initial diversion and buffering, reducing the impact intensity of the water flow. Then, the sealing layer formed by chemical grouting 42 completes secondary interception, constructing a graded pressure-reducing and sealing system. This effectively disperses the concentrated force of high-pressure water inflow on the sealing structure, avoids deformation and damage to a single sealing layer due to continuous impact, significantly improves the impact resistance and long-term stability of the structure under high-pressure and strong water inflow scenarios, and extends the service life of the sealing structure.

[0018] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the bearing component 2 includes a bearing shell 21, a mesh 22, a fixing anchor 23, a fixing plate 24, and a first handle 25. The bearing shell 21 is installed inside the protective component 1. The mesh 22 is fixedly connected to the inner side of the bearing shell 21. The fixing plate 24 is fixedly connected to one side of the mesh 22. The fixing anchor 23 is evenly distributed along the circumference of the bearing shell 21, penetrates the bearing shell 21, and extends outward. The first handle 25 is fixedly connected to one side of the bearing shell 21. The fixing anchor 23 includes an anchor rod and an anchor head. The anchor head is fixedly connected to the outer end of the anchor rod, and the anchor head... It has a conical structure, with the anchor rod threadedly connected to the bearing shell 21, and the inner end of the anchor rod abutting against the mesh 22. The first handle 25 has an annular groove in the middle, which can be used to suspend the hoisting rope, facilitating the installation and disassembly of the bearing component 2. The first handle 25, the second handle 35 and the third handle 44 have the same structure. The protective component includes a protective shell 11, a baffle 12, an anti-corrosion layer 13 and an expansion rubber 14. A movable groove is opened on one side of the protective shell 11, the baffle 12 is movably connected in the movable groove of the protective shell 11, the anti-corrosion layer 13 is fixedly connected to the inner side of the protective shell 11, and the expansion rubber 14 is fixedly connected to the inner side of the anti-corrosion layer.

[0019] In this embodiment, the sealing structure is firmly connected to the surrounding strata through the synergistic effect of the bearing shell 21, the mesh 22 and the anchor 23, which disperse the water pressure and strata stress on the structure. The anchor 23 can be deeply adapted to the strata structure to achieve stable fixation, thereby improving the overall bearing strength of the structure. At the same time, the protective shell 11 and the baffle 12 of the protective component 1 are made of high-strength materials. With the protection of the anti-corrosion layer 13, the structure's deformation resistance is enhanced and it can resist the erosion and damage of groundwater. The dual protection ensures that the sealing structure remains stable under complex geological environment and long-term water flow, avoiding problems such as structural loosening and collapse.

[0020] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the sealing assembly 3 includes a sealing shell 31, a cover plate 32, a rigid filler 33, a rubber strip 34, and a second handle 35. The sealing shell 31 is installed above the expanding rubber 14, the cover plate 32 is fixedly connected to the inner side of the sealing shell 31, the rigid filler 33 is fixedly connected to the inside of the sealing shell 31, the rubber strip 34 is fixedly connected to the outer surface of the rigid filler 33, and the second handle 35 is fixedly connected to one side of the sealing shell 31. The expanding rubber 14 is distributed along the axial direction of the anti-corrosion layer 13 on the side where the sealing shell 31 and the pressure-reducing shell 41 are close to each other, and another set of expanding rubber 14 is arranged on the side where the sealing shell 31 and the bearing shell 21 are close to each other.

[0021] In this embodiment, the expanding rubber 14 of the protective component 1 expands upon contact with water and adheres tightly to the stratum, forming the first sealing barrier; the rubber strip 34 of the sealing component 3 forms a tight connection with the cover plate 32 and the sealing shell 31, and together with the filling and compaction of the rigid filler 33, it constructs the second high-efficiency sealing layer; the chemical grouting 42 penetrates into the stratum fissures and the joints between the components, forming the third full-area sealing network. The multi-seal design effectively avoids problems such as grout loss and water leakage, greatly improves the overall sealing performance of the sealing structure, and completely blocks the path of spring diffusion.

[0022] like Figure 1-5As shown, when a user needs to use a composite structure for sealing underground springs, a comprehensive survey of the spring site is conducted. Based on the measured data, the installation positions of each component, the amount of material filling, and the extension length of the anchor 23 are determined. Using the third handle 44 on the outside of the pressure-reducing shell 41, the pressure-reducing component 4 is hoisted to the preset installation position above the protective shell 11 of the spring channel, ensuring that the permeable gravel 43 faces the direction of the water flow. Polyurethane chemical grout 42 is injected into the other side of the limiting boss through the grouting pipe embedded in the pressure-reducing shell 41. Using the second handle 35 on the outside of the sealing shell 31, the sealing component 3 is hoisted above the pressure-reducing component 4, so that the top of the sealing shell 31 is... Aligning with the top of the pressure relief shell 41, high-strength cement mortar is injected into the cavity formed by the sealing shell 31 and the cover plate 32 through the grouting hole on the cover plate. Then, with the help of the first handle 25 on one side of the bearing shell 21, the bearing assembly 2 is hoisted above the sealing assembly 3, so that the bearing shell 21 is embedded inside the protective shell 11. The top of the bearing shell 21 abuts against the baffle 12 inside the protective shell 11. The buffer rubber pad at the abutment ensures a tight fit. The anchors evenly distributed around the circumference of the bearing shell are rotated and pushed forward through the threaded structure, so that the anchors 23 penetrate the protective shell 11 and extend outward into the stratum. The conical anchor head penetrates into the stratum to achieve a stable anchoring, ensuring that the bearing assembly 2 is firmly connected to the surrounding stratum.
