Description

Technical Field

[0001] The present invention relates to the technical field of compressed air energy storage, and in particular to an adaptive deformation structure of an air storage chamber lining, a lining structure and an air storage chamber. Background Art

[0002] Artificial gas storage chambers are highly safe, have flexible site selection, excellent durability and reasonable economy. Currently, most of the compressed air energy storage power station projects under construction and planned for filing adopt artificial gas storage chambers. Different from artificial chambers such as natural gas storage reservoirs and hydropower transmission tunnels, compressed air energy storage power stations store energy and peak load by continuously circulating gas in the gas storage chamber, which can reach up to 10-15MPa. Therefore, the temperature and pressure of the gas in the gas storage chamber are in a state of mutual influence and cyclic change. The lining and surrounding rock are subjected to the dual effects of cyclic gas pressure and temperature load. The existing concrete lining structure is prone to cracks under frequent pressure fluctuations, and the sealing structure may be sheared or squeezed out at the cracks in the concrete lining, resulting in seal damage, which places high demands on the structural stability and sealing of the chamber. Summary of the invention

[0003] The purpose of the present invention is to overcome the technical problem in the prior art that the concrete lining structure of the gas storage chamber is prone to cracks under pressure fluctuations and causes damage to the sealing layer, and to provide an adaptive deformation structure of the gas storage chamber lining, a lining structure and a gas storage chamber.

[0004] In a first aspect, the present invention provides an adaptive deformation structure of a gas storage chamber lining, comprising a plurality of connecting plates and a deformation member, wherein the plurality of connecting plates are arranged opposite to and in parallel, and the deformation member is arranged between adjacent connecting plates, and the connecting plates can move away from each other when subjected to force so that the deformation member is stretched and deformed, and the deformation member can return to its original state after the force is released.

[0005] The adaptive deformation structure of the present application can be set at the segmented position of the concrete lining of the gas storage chamber, so that the connecting plates on both sides of the deformation structure are fixedly connected to the two concrete lining sections after the segmentation. By utilizing the principle that the deformation member can be stretched and deformed when subjected to tension, the adaptive deformation structure can be adaptively deformed. When the concrete lining is subjected to the internal pressure of the chamber, the deformation position can be concentrated in the adaptive deformation structure, thereby avoiding tensile damage and cracks in the concrete lining under pressure, and also avoiding damage to the sealing layer due to shearing or extrusion along the concrete cracks, thereby ensuring the stability and sealing performance of the chamber structure.

[0006] Preferably, a plurality of the deformation members are provided between adjacent connecting plates, and the deformation member comprises two deformation plates arranged opposite to each other.

[0007] A plurality of deformation members are arranged between the connecting plates, so as to further share the tensile force exerted on the adaptive deformation structure, and the force exerted on each deformation member can be evenly distributed to the two deformation plates, so that the deformation plates can be tensilely deformed at the same time, and elastic deformation can be maintained under working conditions with relatively high pressure, so as to avoid the inability to recover after the pressure is released.

[0008] Preferably, the deformable plate is a curved plate.

[0009] Setting the deformable plate as an arc plate can improve the force range of the adaptive deformation structure, that is, the arc plate can have a stronger adaptive deformation ability when subjected to force, and can meet a higher pressure change range. Here, the deformable plate can be a semicircular ring plate, and two semicircular ring plates are arranged relative to each other to form an annular deformable member overall structure. The two semicircular ring plates are arranged at intervals from each other. Compared with the overall annular structure, dividing the annular ring into two to form two independent semicircular structures can further improve the elastic deformation amount. That is to say, under the same tensile force, the deformation amount of the semicircular ring plate is greater than that of the overall annular structure, and its adaptive deformation effect is better; in addition, the deformable plate and the connecting plate can be fixedly connected by welding or integral forming.

[0010] Preferably, the connecting plate is a corrugated plate.

[0011] The use of corrugated plates in connecting plates can improve rigidity and enhance the structure's ability to resist deformation. The corrugated plates have good toughness and can avoid cracks between the corrugated plates and the concrete lining.

[0012] Preferably, the deformation member is connected to the crest or trough of the corrugated plate.

[0013] Setting the deformation member at the crest or trough of the corrugated plate can make the deformation direction of the deformation member along the circumferential direction of the concrete lining, avoid the deformation member from being misplaced along the radial or longitudinal direction of the lining, and increase the stability of the deformation member joint.

[0014] Preferably, adjacent corrugated plates are arranged symmetrically.

[0015] The symmetrical arrangement of the corrugated plates can increase the distance between the crests or troughs of two adjacent corrugated plates, increase the size of the deformable member, and further increase the deformation range and size of the deformable member, thereby improving the adaptive deformation capability.

[0016] In a second aspect, the present invention provides a lining structure of a gas storage chamber, comprising a plurality of concrete lining segments and the adaptive deformation structure of the gas storage chamber lining as described above, wherein the adaptive deformation structure is arranged between adjacent concrete lining segments.

[0017] The deformation of the concrete lining can be calculated based on the maximum internal pressure in the chamber, and the number of segments of the concrete lining can be obtained.

[0018] Preferably, sealant is provided at the inner side of the lining structure and at the corresponding position of the adaptive deformation structure.

[0019] Providing sealant at segmented locations of the concrete inside the lining can ensure that the lining of the adaptive deformation structure maintains sufficient sealing performance when deformation occurs, thereby avoiding air leakage.

[0020] Preferably, steel bars are provided in the concrete lining section, and both ends of the steel bars are respectively connected to the connecting plates.

[0021] In a third aspect, the present invention provides a gas storage chamber, comprising surrounding rock layers, a lining structure of the gas storage chamber as described above, and a sealing layer arranged in sequence from the outside to the inside.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention provides an adaptive deformation structure of a gas storage chamber lining, a lining structure and a gas storage chamber. The adaptive deformation structure of the present application can be set at a segmented position of the concrete lining of the gas storage chamber. By utilizing the principle that a deformable member can be stretched and deformed when subjected to tension, the adaptive deformation structure can be adaptively deformed. When the concrete lining is subjected to the internal pressure of the chamber, the position where the deformation occurs can be concentrated in the adaptive deformation structure, thereby avoiding tensile damage and cracks in the concrete lining under pressure, and also avoiding damage to the sealing layer due to shearing or extrusion along concrete cracks, thereby ensuring the stability and sealing performance of the chamber structure.

[0039] Example 1

[0040] This embodiment provides an adaptive deformation structure of a gas storage chamber lining.

[0041] Figure 1 It is a schematic diagram of the first structure of the adaptive deformation structure of the gas storage chamber lining of the present invention before deformation; Figure 2 It is a schematic diagram of the first structural deformation of the adaptive deformation structure of the gas storage chamber lining of the present invention; Figure 3 It is a schematic diagram of the second structure of the adaptive deformation structure of the gas storage chamber lining of the present invention before deformation; Figure 4 It is a schematic diagram of the second structural deformation of the adaptive deformation structure of the gas storage chamber lining of the present invention; Figure 5 It is a schematic diagram of the lining structure of the gas storage chamber of the present invention; Figure 6 for Figure 1 A partial enlarged view of point A in the middle. Figure 7 for Figure 2 A partial enlarged view of point B in the middle.

[0042] like Figures 1 to 7 As shown in, the adaptive deformation structure of the gas storage chamber lining includes a plurality of connecting plates 11 and deformable members 12. The plurality of connecting plates 11 are arranged oppositely and in parallel, and the deformable members 12 are arranged between adjacent connecting plates 11. The deformable members 12 can be stretched and deformed, and can also return to their original shape after the force is unloaded; for example, there are four connecting plates 11, and the four connecting plates 11 are arranged at intervals from each other. A deformable member 12 is provided between two adjacent connecting plates 11, that is, the deformable member 12 can be three-layered, and the connecting plates 11 on both sides of the deformable member 12 can stretch and elastically deform the deformable member 12 when subjected to opposite tensile forces, thereby increasing the spacing between the connecting plates 11, and after the tensile forces acting on the connecting plates 11 and the deformable members 12 are unloaded, the deformable members 12 can return to their original shape under the elastic action of their materials.

[0043] The adaptive deformation structure 1 of the present application can be set at the segmented position of the concrete lining of the gas storage chamber. By utilizing the principle that the deformable member 12 can be stretched and deformed when subjected to tension, the adaptive deformation structure 1 can be adaptively deformed. When the concrete lining is subjected to the internal pressure of the chamber, the deformation position can be concentrated in the adaptive deformation structure 1, thereby avoiding tensile damage and cracks in the concrete lining under pressure, and also avoiding damage to the sealing layer 4 due to shearing or extrusion along the concrete cracks, thereby ensuring the stability and sealing performance of the chamber structure.

[0044] Specifically, six groups of deformation members 12 may be arranged between two adjacent connecting plates 11, and each group of deformation members 12 may include two deformation plates 121 arranged opposite to each other. Of course, the number of the above-mentioned connecting plates 11, the number of deformation members 12 between adjacent connecting plates 11, and the number of deformation plates 121 in each group of deformation members 12 may be selected according to actual needs, and the present invention does not specifically limit this.

[0045] A plurality of deformation members 12 are arranged between the connecting plates 11, which can further share the tensile force applied to the adaptive deformation structure 1, and the force applied to each deformation member 12 can be evenly distributed to the two deformation plates 121, so that the deformation plates 121 can be tensilely deformed at the same time, and elastic deformation can be maintained under high pressure conditions to avoid failure to recover after the pressure is released.

[0046] In this embodiment, the deformable plate 121 is an arc-shaped plate, specifically, the deformable plate 121 can be a semicircular deformable steel ring; setting the deformable plate 121 as an arc-shaped plate can improve the force range of the adaptive deformation structure 1, that is, the arc-shaped plate can have a stronger adaptive deformation ability when subjected to force, and can meet a higher pressure change range. However, the present invention is not limited to this, and the type of the deformable plate 121 can also be an angle plate with a cross section similar to a broken line, or other deformable shapes; in addition to including the deformable plate 121, the deformable member 12 can also be composed of other elastic deformation structures, such as a spring, and the present invention does not specifically limit this.

[0047] Here, the deformation plate 121 can be a semicircular ring plate. The two semicircular ring plates are arranged relative to each other to form an annular deformation member 12 as an overall structure. The two semicircular ring plates are arranged at intervals from each other. Compared with the overall circular ring structure, dividing the circular ring into two independent semicircular structures can further increase the elastic deformation. That is to say, under the same tensile force, the deformation of the semicircular ring plate is greater than that of the overall circular ring structure, and its adaptive deformation effect is better. In addition, the deformation plate and the connecting plate can be fixedly connected by welding or integral forming.

[0048] Alternatively, the connecting plate 11 may be a corrugated plate (such as Figure 3 or Figure 4), or a plain steel plate (as shown in Figure 1 or Figure 2 The connecting plate 11 adopts a corrugated plate structure to improve rigidity and enhance the structure's ability to resist deformation. The corrugated plate has good toughness and can avoid cracks between the corrugated plate and the concrete lining.

[0049] The material of the connecting plate 11 and the deformable part 12 can be steel. Steel has sufficient elasticity and can undergo elastic deformation when subjected to force, and can also recover under the elastic action after the external force is removed; however, the present invention is not limited to this. The material of the connecting plate 11 and the deformable part 12 can also be selected according to actual needs, and the present invention does not make specific limitations on this.

[0050] Optionally, the deformation member 12 can be connected to the crest or trough of the corrugated plate; placing the deformation member 12 at the crest or trough of the corrugated plate can limit the deformation direction of the deformation member 12 to the circumferential direction of the concrete lining, avoid the deformation member 12 from being misplaced in the radial or longitudinal direction of the lining, and increase the stability of the deformation member joint. Specifically, when there is a tendency for the connection plates 11 to be misplaced in the radial or longitudinal direction of the lining, the deformation member 12 can abut against the arc portion of the corrugated plate to prevent the arc plates from being misplaced.

[0051] In this embodiment, adjacent corrugated plates are symmetrically arranged; the symmetrical arrangement of adjacent corrugated plates means that the bending directions between the two corrugated plates are opposite, and a wider gap can be formed between the two corrugated plates, which can increase the size of the deformable member 12 installed in the gap, thereby improving the deformation range and size of the deformable member 12 and improving the adaptive deformation capability.

[0052] The connecting plate 11 and the deformable part 12 in the above-mentioned adaptive deformation structure 1 can be welded by high-elasticity and high-strength alloy steel, so that they have good toughness and fatigue resistance. The connecting plate 11 and the deformable part 12 can also be integrally formed and connected. The present invention does not specifically limit the specific materials of each component and the connection method between the components.

[0053] Example 2

[0054] This embodiment provides a lining structure for a gas storage chamber.

[0055] The lining structure of the gas storage chamber described in this embodiment includes a plurality of concrete lining sections 2 and the adaptive deformation structure of the gas storage chamber lining as described in Example 1. The adaptive deformation structure 1 is arranged between adjacent concrete lining sections 2.

[0056] The concrete lining section 2 can be used as the basic lining part, and several deformation-induced joints can be formed between multiple concrete lining sections 2. The specific lining thickness is calculated and determined in combination with the surrounding rock conditions and operating internal pressure and other working conditions of different projects, and the specific number of joints is determined in combination with the maximum compression of the surrounding rock and the increase in the circumference of the chamber. In other words, the circumferential deformation of the concrete lining can be calculated based on the maximum internal pressure in the chamber, and combined with the deformable amount of each adaptive deformation structure 1, the number of segments of the concrete lining and the number of adaptive deformation structures 1 can be obtained.

[0057] In this embodiment, a sealant 3 is provided at the inner side of the lining structure and at the corresponding position of the adaptive deformation structure 1; here, the specific form of the sealant 3 can be a polymer rubber strip, which can be closely attached to the inner side of each deformation induced joint, that is, the corresponding position of the adaptive deformation structure 1, to ensure the air tightness of the structure; the sealant 3 is provided at the segmented position of the concrete on the inner side of the lining to ensure that the lining of the adaptive deformation structure 1 maintains sufficient sealing performance when deformation occurs to avoid air leakage.

[0058] When the adaptive deformation lining structure of the artificial gas storage chamber is in maintenance condition, Figure 1 or Figure 3 As shown in , the pressure and temperature inside the chamber drop, the concrete lining structure is mainly subjected to the surrounding rock and soil pressure and is in a compressed state, and the semicircular steel ring (deformation member 12) at the structural joint is compressed; when the adaptive deformation lining structure of the artificial gas storage chamber is in the operating condition, as shown in Figure 2 or Figure 4 As shown in the figure, the direction of the arrow is the direction of the pressure. Under the action of high internal pressure, the temperature inside the chamber rises, the concrete structure produces tensile stress, the semicircular steel ring structure at the joint opens, concentrated deformation occurs at the steel joint, and the lining stress is dispersed. At the same time, the polymer rubber strip is elongated with the deformation trend of the joint to maintain the air tightness at the joint.

[0059] In this embodiment, a steel bar (not shown) is provided in the concrete lining section 2, and both ends of the steel bar are respectively connected to the connecting plate 11. The steel bar can be connected to the connecting plate 11 by welding or integrally forming, so that the overall structure of the concrete lining section 2 can be kept stable and the movement and dislocation between the connecting plate 11 and the concrete lining can be avoided. Specifically, the concrete lining section 2 uses C45 waterproof concrete.

[0060] It should be noted that the adaptive deformation structure of the gas storage chamber lining described in this embodiment is consistent with the adaptive deformation structure of the gas storage chamber lining described in Example 1, and this embodiment will not be further described in detail.

[0061] The lining structure of the gas storage chamber of the present invention may include a basic lining portion (i.e., a concrete lining section 2) and a deformation-induced joint (i.e., a gap between the concrete lining sections 2). The basic lining portion is constructed with high-strength concrete to form the basic skeleton of the chamber. The deformation-induced joints are evenly distributed on the secondary lining structure, dividing the lining structure into a number of independent but interconnected units. Each joint may be composed of three rows of semicircular deformable steel rings (deformation plates 121) and end steel plates (connecting plates 11). The semicircular deformable steel rings have good elasticity and toughness, and can undergo elastic deformation when the chamber is deformed, absorbing and dispersing stress. The end steel plates are used to fix the semicircular deformable steel rings and are connected to the concrete lining through steel bars.

[0062] The characteristic of the present invention is that a polymer rubber material is arranged on the inner side of each adaptive deformation structure 1. The polymer rubber material has a certain elasticity and can deform and expand and contract according to the opening and closing of the deformation steel ring, always keeping the lining structure joints sealed to ensure the sealing of the lining structure; according to different surrounding rock conditions, the maximum compression of the surrounding rock and the increase in the circumference of the chamber under the action of the chamber pressure are calculated, and combined with the deformation of a single adaptive deformation structure 1, the expansion rate of the polymer rubber material and the number of adaptive deformation structures 1 are calculated to make the lining structure meet the expansion and deformation requirements of the chamber.

[0063] Example 3

[0064] This embodiment provides a gas storage chamber.

[0065] The gas storage chamber described in this embodiment may include surrounding rock layers (not shown in the figure) arranged in sequence from the outside to the inside, the lining structure of the gas storage chamber as described in Example 2, and a sealing layer 4.

[0066] After the excavation of the chamber, the initial support of shotcrete is first carried out. The joint position is marked before tying the secondary lining steel bars. The prefabricated adaptive deformation structure 1 is installed at the marked position. The adaptive deformation structure 1 divides the secondary lining structure into several blocks, and the secondary lining steel bars are tied in blocks. The secondary lining main bars are welded to the connecting plate 11. After the construction of the joint joint is completed, a special template trolley is used to cast each concrete lining, and the connecting plate 11 is used as the annular end template for pouring the lining concrete. After the secondary lining concrete is cured to the design strength, a polymer rubber strip is installed on the inside of each joint, and the rubber strip is fixed to the inside of the concrete lining by a low-temperature vulcanization process, so that it is closely attached to the adaptive deformation structure 1 and forms a whole with the secondary lining structure. The polymer rubber strip can still maintain a close fit with the lining structure under the conditions of filling and deflation during the operation and maintenance of the chamber, and serves as the second airtight insurance outside the sealing layer 4 of the artificial gas storage chamber, effectively preventing compressed gas leakage.

[0067] In summary, the present invention provides an adaptive deformation structure of a gas storage chamber lining, a lining structure and a gas storage chamber. The adaptive deformation structure of the present application can be set at a segmented position of the concrete lining of the gas storage chamber. By utilizing the principle that the deformable member can be stretched and deformed when subjected to tension, the adaptive deformation structure can be adaptively deformed. When the concrete lining is subjected to the internal pressure of the chamber, the deformation position can be concentrated in the adaptive deformation structure, thereby avoiding tensile damage and cracks in the concrete lining under pressure, and also avoiding damage to the sealing layer due to shearing or extrusion along the concrete cracks, thereby ensuring the stability of the chamber structure and the sealing performance.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
