[0061] In view of this, the present invention provides a cage-type anchor bolt sealed inner lining structure, an underground silo for compressed air energy storage power stations and its construction method, which is simple to construct, highly efficient, has excellent sealing performance, and is inexpensive, thus making it more suitable for practical use.

In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0063] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can mean that A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0064] Cage-type anchor bolt sealing liner structure

[0065] See appendix Figure 1 - Appendix Figure 5The cage-type anchor bolt sealing liner structure provided in this embodiment of the invention includes a skeleton 2, a fixed base plate 3, multiple sealing layers 5, and a cage-type anchor bolt fastener. A hollow surface is formed between the skeleton 2. The skeleton 2 is adapted to the fixed base plate 3. After the skeleton 2 and the fixed base plate 3 are assembled, a sealing layer retaining groove is formed between the skeleton 2 and the fixed base plate 3. The sealing layers 5 are spread within the hollow surface, and the free edges of the sealing layers 5 fill the sealing layer retaining groove, so that multiple sealing layers 5 are connected as a whole. A first gap exists between the free edges of two sealing layers 5 located in the same sealing layer retaining groove. The cage-type anchor bolt fastener is inserted into the first gap, so that the free edges of two sealing layers 5 located in the same sealing layer retaining groove are respectively press-fitted with the cage-type anchor bolt fastener, forming a cage-type anchor bolt sealing liner structure.

[0066] The cage-type anchor-type sealing lining structure provided in this embodiment of the invention can connect the sealing layer 5 using the sealing layer retaining groove formed between the frame 2 and the fixed base plate 3 after assembly. The free edges of the sealing layer 5 are filled into the sealing layer retaining groove, creating a fitting between the sealing layer 5 and the groove. The free edges of the two sealing layers 5 within the same retaining groove are interference-fitted with the cage-type anchor-type fixing component, thus preventing displacement or detachment of the sealing layer 5 and ensuring airtightness. Therefore, when formed inside the concrete lining layer 1 of the underground chamber of a compressed air energy storage power station, its construction period is shorter and the cost is lower than that of welded steel plates. It has good sealing performance, and the components are easy to replace and maintain. Under the premise of ensuring tightness, its airtightness meets the usage requirements. Furthermore, the sealing layer 5 has a short construction period, and the components can be prefabricated. Compared with the traditional steel plate lining which requires on-site welding, it can save a lot of construction time and reduce costs. During maintenance, damaged parts can be directly replaced.

[0067] The skeleton 2 includes a warp skeleton 21 and a weft skeleton 22. The warp skeleton 21 and the weft skeleton 22 interweave to form a cylindrical shape, creating openings between adjacent warp skeletons 21 and adjacent weft skeletons 22. In this embodiment, the warp skeleton 21 and the weft skeleton 22 are evenly distributed, thus enabling the cage-type anchor-type sealing liner structure provided by this embodiment to be isotropic. When prefabricating the sealing layer 5, only a standard prefabricated sealing layer 5 needs to be manufactured to facilitate replacement when components are damaged.

[0068] The cage-type anchor-type sealing liner structure provided in this embodiment of the invention also includes an arc-shaped skeleton 23. The arc-shaped skeleton 23 is the warp skeleton of the weft skeleton 22 near both ends of the skeleton 2. The diameter of the weft skeleton 22 gradually decreases near the ends of the cylindrical structure. One end of the arc-shaped skeleton 23 is connected to the larger diameter weft skeleton 22, and the other end is connected to the smaller diameter weft skeleton 22, causing the diameter of the cylindrical structure to gradually shrink at both ends in the axial direction, forming a dome. In this case, because the cage-type anchor-type sealing liner structure provided in this embodiment of the invention also includes the arc-shaped skeleton 23, a dome can be formed at both ends in the axial direction, thus making the application range of the cage-type anchor-type sealing liner structure provided in this embodiment of the invention wider. In this case, the sealing layer 5 between two adjacent arc-shaped skeletons 23 has different specifications than the sealing layer 5 between the warp skeleton 21 and the weft skeleton 22. Therefore, it is necessary to prefabricate replacement sealing layer 5 components according to the dimensions of the arc-shaped skeleton 23.

[0069] Viewed from the radial section of the fixed base plate 3, the fixed base plate 3 includes a bottom and two side walls. The two side walls are fixedly connected to the bottom on one side, and two sealing layer hooks are correspondingly arranged facing each other on the other side of each side wall. A second gap exists between the two sealing layer hooks, wherein the axial width of the second gap is greater than the axial width of the first gap. The free edges of the two sealing layers 5 are respectively embedded in the second gap through the corresponding two sealing layer hooks, thus creating a first gap between the free edges of the two sealing layers 5. In this configuration, the two side walls of the fixed base plate 3 engage with the free edges of the two sealing layers 5 located in the same locking groove using hooks, resulting in a more stable and reliable connection.

[0070] The cage-type anchor bolt fastener includes a reinforcing cage 4, an anchor bolt 6, and a fastening nut 7. The reinforcing cage 4 is inserted into the first gap, so that the side wall of the reinforcing cage 4 has an interference fit with the free edges of the corresponding two sealing layers 5. The anchor bolt 6 passes through the core hole of the reinforcing cage 4, so that one end of the anchor bolt 6 terminates at the bottom of the fixed base plate 3, and the other end of the anchor bolt 6 has a free end. The fastening nut 7 is fastened to the free end of the anchor bolt 6. In this case, the interference fit between the side wall of the reinforcing cage 4 and the free edges of the corresponding two sealing layers 5 can reduce or avoid the displacement or detachment of the free edges of the two sealing layers 5, making the setting of the sealing layers 5 more stable and reliable.

[0071] The steel cage 4 includes multiple meridional bars and multiple latitudinal bars, which are connected in a crisscross pattern to form a cylindrical structure. In this case, the connection stability between the steel cage 4 and the free edges of the two sealing layers 5 can be increased through these multiple meridional bars and multiple latitudinal bars.

[0072] In this embodiment, the frame 2 and the fixed base plate 3 are integrally formed. In this embodiment, the integral forming of the frame 2 and the fixed base plate 3 can be achieved using CAD cutting or CAM cutting. The integral forming process has no connecting joints, which reduces stress concentration and thus extends the lifespan of the cage-type anchor-type sealing liner structure provided in this embodiment of the invention.

[0075] The cage-type anchor-type sealing lining structure provided in this embodiment of the invention is formed inside the concrete lining layer 1 of the underground cavern of a compressed air energy storage power station. Its construction period is shorter and the cost is lower than that of welded steel plates. It possesses excellent sealing performance, and its components are easy to replace and maintain. While ensuring tightness, its airtightness meets the usage requirements. Furthermore, this sealing layer 5 has a short construction period, and its components can be prefabricated. Compared to the disadvantages of traditional steel plate linings that require on-site welding, it can save a lot of construction time and reduce costs. During maintenance, damaged parts can be directly replaced.

[0076] The underground chamber of the compressed air energy storage power station also includes fasteners 7. Fasteners 7 pass through the frame 2 and the fixed base plate 3, and terminate within the concrete lining layer 1. In this case, by fixing the cage-type anchor-type sealing lining structure provided in this embodiment of the invention to the concrete lining layer 1 using fasteners 7, the possibility of the cage-type anchor-type sealing lining structure provided in this embodiment of the invention shifting within the concrete lining layer 1 can be reduced, thereby ensuring the implementation stability of the underground chamber of the compressed air energy storage power station provided in this embodiment of the invention.

[0077] The inner wall of the concrete lining layer 1 is provided with a receiving groove. The shape of the receiving groove is adapted to the shape of the fixed base plate 3, so that the fixed base plate 3 is embedded in the receiving groove. In this case, the limiting effect formed by the side wall of the receiving groove itself can be used to prevent the fixed base plate 3 from shifting relative to the concrete lining layer 1, so that the underground cavern of the compressed air energy storage power station provided in this embodiment of the invention has better application stability.

[0078] Construction method of underground cavern for compressed air energy storage power station

[0079] The construction method for the underground chamber of the compressed air energy storage power station provided by this invention includes the following steps:

[0080] Step S1: Install a fixed base plate 3 on the inner wall of the underground chamber of the compressed air energy storage power station;

[0081] Step S2: Install the frame 2 on the inner wall of the underground cavern of the compressed air energy storage power station, so that the frame 2 and the fixed base plate 3 are assembled, a sealing layer locking groove is formed between the frame 2 and the fixed base plate 3, and a hollow surface is formed between the frames 2.

[0082] Step S3: Spread the sealing layer 5 in the hollow surface, and fill the free edge of the sealing layer 5 into the sealing layer locking groove, so that multiple sealing layers 5 are connected into one to form a cage-type anchor rod type sealing liner structure.

[0083] Step S4: Fix the cage-type anchor-type sealing lining structure to the inner wall of the concrete lining layer 1.

[0084] The construction method for the underground silo of a compressed air energy storage power station provided in this embodiment of the invention enables the cage-type anchor-type sealing lining structure provided in this embodiment to be formed inside the concrete lining layer 1 of the underground silo of the compressed air energy storage power station. Its construction period is shorter than that of welded steel plates, its cost is lower, it has good sealing performance, and its components are easy to replace and maintain. Under the premise of ensuring tightness, its airtightness meets the usage requirements. In addition, the sealing layer 5 has a short construction period, and the components can be prefabricated. Compared with the disadvantage of traditional steel plate lining requiring on-site welding, it can save a lot of construction time and reduce costs. During maintenance, damaged parts can be directly replaced.

[0085] The construction method for the underground chamber of the compressed air energy storage power station includes the following steps before the step of installing the fixed base plate 3 on the inner wall of the underground chamber:

[0086] On the inner wall of the concrete lining layer 1, a receiving groove is chiseled at a position corresponding to the fixed base plate 3. The shape of the receiving groove is adapted to the fixed base plate 3 so that the fixed base plate 3 can be embedded in the receiving groove.

[0087] In this case, the limiting effect formed by the side wall of the accommodating tank itself can be used to prevent the fixed bottom plate 3 from shifting relative to the concrete lining layer 1, thus making the application stability of the underground cavern of the compressed air energy storage power station provided in this embodiment of the invention better.

[0088] The construction method for the underground cavern of the compressed air energy storage power station also includes the following steps:

[0089] Gas storage tests were conducted on the underground chamber of the compressed air energy storage power station to determine the sealing performance of the underground chamber;

[0090] Real-time monitoring is conducted to identify potential air leakage points in the underground chambers of the compressed air energy storage power station.

[0091] In this situation, by monitoring the potential leak points in the underground chambers in real time, any leaks can be detected and remedied promptly.

[0092] In the process of real-time monitoring of potential air leakage points in the underground chamber of the compressed air energy storage power station, the potential air leakage points include: the connection between the sealing layer 5 and the fixed base plate 3, the connection between the fixed base plate 3 and the frame 2, the connection between the fixed base plate 3 and the concrete lining layer 1, and one or more locations within the sealing layer 5 itself. In this way, it is possible to accurately monitor potential air leakage points in the underground chamber in real time.

[0093] The real-time monitoring of potential gas leakage points in underground caverns specifically includes the following steps:

[0094] At potential leak points in the underground chamber of the compressed air energy storage power station, gas flow monitoring instruments are installed, and location labels are set for each gas flow monitoring instrument.

[0095] Set alarm thresholds for the gas flow monitoring instrument based on its location;

[0096] When an abnormal gas flow alarm is detected, the location of the leak in the underground chamber of the compressed air energy storage power station is determined based on the location label of the gas flow monitoring instrument that triggered the alarm.

[0097] In this situation, once a potential leak occurs in the underground chamber, the leak location can be accurately determined based on the alarm information and the location label of the gas flow monitoring instrument, allowing for emergency repair measures to be taken.
