Abstract
Description
Technical Field
[0001] The invention relates to the technical field of compressed gas energy storage artificial underground gas storage structure, and in particular to a concrete lining joint sealing structure and a gas storage chamber. Background Art
[0002] Compressed air energy storage is a technology for storing electrical energy. It compresses and stores air in large gas storage chambers (such as underground salt caverns, abandoned mines, and artificial lined chambers) by using excess electricity to drive compressors during periods of low electricity demand. When the peak period of electricity demand arrives, the compressed air will be released and heated to drive the turbine generator to generate electricity, thereby converting the previously stored energy back into electricity for use.
[0003] At present, artificial gas storage chambers have become a widely studied gas storage method due to their flexible location and large gas storage capacity. Unlike traditional underground chambers, compressed gas energy storage chambers need to achieve gas sealing under the action of high temperature and high internal pressure circulation. In order to enhance the sealing performance, a sealing layer needs to be set inside the lining layer.
[0004] The sealing layer is usually made in the following two ways:
[0005] 1. A steel plate sealing layer is set inside the lining, which is close to the chamber lining. However, due to the high rigidity of the steel plate and its weak ability to coordinate deformation with the lining and surrounding rock, it will be subjected to large hoop tensile stress. Therefore, in order to avoid the steel plate from breaking due to excessive hoop stress as much as possible, thicker steel plates must be used. However, thicker steel plates will lead to an increase in construction costs.
[0006] 2. Considering the strong deformation ability and relatively low cost of flexible materials, a flexible sealing layer is set inside the lining to fit the chamber lining. However, under the action of high internal pressure, the concrete lining structure of the chamber will inevitably crack, and the crack position is random. When the crack width is too large, the flexible sealing layer may be pressed into the lining crack under high internal pressure, causing leakage in the gas storage chamber. Summary of the invention
[0007] The purpose of the present invention is to overcome the problems of sealing of chamber structures existing in the prior art. First, the chamber lining is not divided into blocks, and a steel plate that is in close contact with the chamber lining is arranged inside the lining in a whole ring. However, thicker steel plates are required, which increases the cost. Second, a flexible sealing layer that is in close contact with the chamber lining is arranged inside the lining in a whole ring. However, the flexible sealing layer may be damaged by seams under high internal pressure, resulting in leakage of the gas storage chamber. A concrete lining seam sealing structure and a gas storage chamber are provided.
[0008] In a first aspect, the present invention provides a concrete lining joint sealing structure, comprising:
[0009] At least two segment linings, the segment linings are arranged at intervals along the lining design position of the chamber, and there is a structural joint between two adjacent segment linings;
[0010] At least one set of rigid connection components, the rigid connection components comprising a first connection member and a second connection member, the first connection member and the second connection member are respectively connected to inner surfaces of two adjacent segment linings, the first connection member and the second connection member overlap at the structural seam, and the first connection member and the second connection member can approach or move away from each other;
[0011] A filling piece, wherein the filling piece is used to fill the structural seam and the overlap between the first connecting piece and the second connecting piece.
[0012] The filling element can be a rubber component, a sealing foam or a sealing paste.
[0013] When the gas is compressed and stored in the chamber, the gas pressure is evenly distributed throughout the space and exerts an outward thrust on the inner wall of the concrete lining. This thrust will produce circumferential tensile stress, which will lead to cracking of the concrete lining. To this end, the present application adopts a block-type concrete segment lining, and shear members and structural joints are set between adjacent segment linings. The structural joint can absorb the deformation of the chamber concrete lining caused by the circumferential stress as much as possible, effectively reduce the circumferential tensile stress of the concrete lining, and avoid the cracking of the segment lining and the random location of the cracks to the greatest extent.
[0014] Filling the structural joints with filling pieces is beneficial to ensuring the airtightness of the chamber and is also convenient for repairing the chamber after cracks occur at the structural joints.
[0015] A segmented steel lining sealing layer is arranged on the inner side of the segmented segment lining, which is connected by a rigid connector. The rigid connection assembly includes a first connector and a second connector, which overlap at the structural joint, and the first connector and the second connector can be close to or far away from each other. Compared with the use of a whole ring of steel plate sealing layer in the prior art, the rigid connection assembly of the present application can make the steel lining sealing layer adapt to larger deformation, reduce the annular tensile stress of the steel lining sealing layer under high internal pressure, thereby thinning the thickness of the steel lining sealing layer and reducing the construction cost; compared with the prior art setting a whole ring of flexible sealing layer, the rigid connection assembly arranged at intervals and overlapped can also avoid the occurrence of seam damage. Combined with the segmented concrete segment lining, it can effectively prevent the thin steel plate sealing layer from being damaged due to being pressed into the lining cracks, resulting in gas leakage. In addition, the overlap design of the rigid connection assembly at the structural joint of the concrete lining segment has a limiting effect on the filling piece between the two segment lining structural joints, avoiding the situation where the filling piece is squeezed out. At the same time, the overlapping parts of the rigid connection components are also filled with filling pieces, which can avoid leakage problems caused by extrusion or tearing of the filling pieces to the greatest extent.
[0016] Preferably, one end of the second connecting member is fixed to the inner wall of one of the linings, and the other end extends toward the segment lining on the other side of the structural joint and exceeds the structural joint.
[0017] The second connecting piece covers the structural seam to avoid leakage at the structural seam as much as possible.
[0018] Preferably, the first connecting member is provided with a connecting portion and an overlapping portion, the connecting portion is used to connect the inner wall of the segment lining, the overlapping portion is used to overlap the second connecting member, the overlapping portion extends to the segment lining on the other side of the corresponding structural joint, and the connecting portion and the overlapping portion are located in two planes.
[0019] The connecting portion and the overlapping portion are respectively located on two planes perpendicular to the radial direction of the chamber. The overlapping portion and the connecting portion are respectively located on two planes, which is convenient for overlapping the second connecting portion and arranging a filling piece at the overlapping position.
[0020] Preferably, embedded steel plates are provided inside the segment lining.
[0021] An embedded steel plate is arranged inside the lining to facilitate the installation of the first connecting piece and the second connecting piece.
[0022] Preferably, the first connecting member and the second connecting member are both welded to the embedded steel plate.
[0023] Preferably, the first connecting member and the second connecting member are provided with screw holes, and bolts pass through the screw holes and extend into the inner wall of the segment lining.
[0024] Preferably, the structural joint between two adjacent segment linings is provided with a shear member.
[0025] The shear member can be a shear key, a shear pin or a shear nail, etc. A shear member is arranged between two adjacent segment linings to avoid the misalignment and deformation of the two adjacent segment linings as much as possible, which affects the structural stability of the chamber, and can also provide a smooth supporting surface for the internal sealing layer of the lining.
[0026] Preferably, the shear resistant member is a shear pin, and both ends of the shear pin are respectively anchored to the side walls of two adjacent segment linings.
[0027] The two ends of the shear pin are anchored to the side walls of the two adjacent segment linings facing the structural joint, which can avoid the misalignment of the two adjacent segment linings as much as possible, thereby affecting the structural stability of the chamber.
[0028] Preferably, it further comprises fixing steel bars, wherein the fixing steel bars extend into the side wall of the segment lining facing the structural joint, and the fixing steel bars are used to fix the shear pins.
[0029] The fixing steel bars extend into the side walls of the segment lining and are used to fix the shear pins, which helps to ensure the stability of the shear pins and avoid dislocation of the segment lining as much as possible.
[0030] In a second aspect, the present invention provides a gas storage chamber comprising a concrete lining joint sealing structure as described above.
[0031] A gas storage chamber includes a concrete lining joint sealing structure as described above, which can absorb the deformation of the chamber concrete segment lining caused by the circumferential stress and avoid the segment lining cracking and misalignment as much as possible. A steel plate sealing layer connected by a rigid connector is arranged on the inner side of the lining. The rigid connection assembly can make the steel plate sealing layer adapt to large deformation and reduce the circumferential tensile stress of the steel lining sealing layer, thereby reducing the thickness of the steel lining sealing layer, which is conducive to reducing the construction cost. Combined with the block-type concrete segment lining, it can effectively prevent the thin steel plate sealing layer from being damaged due to being pressed into the lining cracks and causing gas leakage. In addition, the overlap design of the rigid connection assembly at the structural joint of the concrete lining segment has a limiting effect on the filling piece between the two segment lining structural joints, avoiding the situation where the filling piece is squeezed out. At the same time, the overlap of the rigid connection assembly is also filled with filling pieces, which can avoid leakage problems caused by the extrusion or tearing of the filling piece to the greatest extent.
[0032] Compared with the prior art, the present invention has the following beneficial effects:
[0033] 1. The present invention provides a concrete lining joint sealing structure, comprising at least two segment linings, a filling piece and a rigid connection assembly of a segmented sealing steel plate. The segment lining is used, and the segment lining is arranged at intervals along the design position of the lining, so that a structural joint is formed between two adjacent segment linings, and a shear member is arranged between the segments. The structural joint can absorb the deformation of the chamber concrete lining due to the circumferential stress as much as possible, effectively reduce the circumferential tensile stress of the concrete lining, and avoid the cracking of the segment lining and the random cracking position to the greatest extent. A segmented steel lining sealing layer is arranged on the inner side of the segmented segment lining, which is connected by a rigid connector. The rigid connection assembly includes a first connection member and a second connection member, which overlap at the structural joint, and the first connection member and the second connection member can approach or move away from each other. Compared with the use of a whole ring of steel plate sealing layer in the prior art, the rigid connection assembly of the present application can make the steel lining sealing layer adapt to larger deformation, reduce the annular tensile stress of the steel lining sealing layer under high internal pressure, thereby reducing the thickness of the steel lining sealing layer and reducing the construction cost; compared with the prior art setting a whole ring of flexible sealing layer, the rigid connection assembly with interval arrangement and overlap can also avoid the occurrence of seam damage. Combined with the block-type concrete segment lining, it can effectively prevent the thin steel plate sealing layer from being damaged due to being pressed into the lining cracks and causing gas leakage. In addition, the overlap design of the rigid connection assembly at the structural joint of the concrete lining segment plays a limiting role on the filling piece between the two segment lining structural joints, avoiding the situation where the filling piece is squeezed out. At the same time, the overlap of the rigid connection assembly is also filled with filling pieces, which can avoid leakage problems caused by the extrusion or tearing of the filling piece to the greatest extent. A concrete lining joint sealing structure overcomes the existing means of enhancing the sealing of the chamber structure in the prior art. First, the chamber lining is not divided into blocks, and a steel plate that is in close contact with the chamber lining is arranged inside the lining in a whole ring, but thicker steel plates are required, which increases the cost; second, a flexible sealing layer that is in close contact with the chamber lining is arranged inside the lining in a whole ring, but the flexible sealing layer may be damaged by cracks under high internal pressure, causing leakage of the gas storage chamber.

A steel plate sealing layer connected by a rigid connector is arranged on the inner side of the lining. The rigid connection assembly can make the steel plate sealing layer adapt to large deformation, reduce the circumferential tensile stress of the steel lining sealing layer, thereby reducing the thickness of the steel lining sealing layer, which is conducive to reducing the construction cost. Combined with the block-type concrete segment lining, it can effectively prevent the thin steel plate sealing layer from being damaged due to being pressed into the lining cracks, resulting in gas leakage. In addition, the overlap design of the rigid connection assembly at the structural seam of the concrete lining segment plays a limiting role on the filling piece between the two segment lining structural seams, avoiding the situation where the filling piece is squeezed out. At the same time, the overlap of the rigid connection assembly is also filled with filling pieces, which can avoid leakage problems caused by the extrusion or tearing of the filling piece to the greatest extent.

[0046] Example 1
[0047] like Figures 1 to 4 As shown, a concrete lining joint sealing structure comprises:
[0048] At least two segment linings 1, wherein the segment linings 1 are arranged at intervals along the lining design position of the chamber, and a structural joint is provided between two adjacent segment linings 1;
[0049] At least one set of rigid connection components, the rigid connection components comprising a first connection member 3 and a second connection member 4, the first connection member 3 and the second connection member 4 are respectively connected to the inner surfaces of two adjacent segment linings 1, the first connection member 3 and the second connection member 4 are overlapped at the structural seam between the two adjacent segment linings 1, and the first connection member 3 and the second connection member 4 can approach or move away from each other;
[0050] A filling piece 2 is used to fill the structural joint and the overlap between the first connecting piece 3 and the second connecting piece 4.
[0051] Because when the gas is compressed and stored in the chamber, the gas molecules will be evenly distributed in the entire space and exert an outward thrust on the inner wall of the lining. This pressure will cause the lining material to be subjected to radial tensile stress, and this pressure will also cause the lining material to be subjected to circumferential stress in the circumferential direction. Circumferential stress can easily cause the lining to crack.
[0052] When the gas is compressed and stored in the chamber, the gas pressure is evenly distributed throughout the space and exerts an outward thrust on the inner wall of the concrete lining. This thrust will produce circumferential tensile stress, which will cause the concrete lining to crack. Therefore, the present application uses segment lining 1, and the segment lining 1 is arranged at intervals along the designed position of the lining, so that a structural joint is formed between two adjacent segment linings 1. The structural joint can absorb the deformation of the chamber concrete lining due to the circumferential stress as much as possible, effectively reduce the circumferential tensile stress of the concrete lining, and avoid the cracking of the segment lining 1 and the random cracking position to the greatest extent; the shear member 7 can effectively reduce the misalignment deformation of the two lining segments. Provide a smooth support surface for the internal sealing layer of the lining.
[0053] At the same time, filling the filling piece 2 inside the structural seam is conducive to ensuring the sealing of the chamber, and the chamber is also easy to repair after cracking at the structural seam. The rigid connection assembly includes a first connection piece 3 and a second connection piece 4, which overlap at the structural seam, and the first connection piece 3 and the second connection piece 4 can be close to or far away from each other. Compared with the steel plate with a whole ring set in the prior art, the rigid connection assembly of the present application can make the steel lining sealing layer adapt to larger deformation, reduce the annular tensile stress of the steel lining sealing layer under high internal pressure, thereby reducing the thickness of the steel lining sealing layer and reducing the construction cost. Combined with the block-type concrete pipe segment lining 1, it can effectively prevent the thin steel plate sealing layer from being damaged due to being pressed into the lining cracks and causing gas leakage. In addition, the overlap design of the rigid connection assembly at the structural seam of the concrete lining pipe segment has a limiting effect on the filling piece 2 between the two pipe segment linings 1 to avoid being squeezed out. And the overlap of the rigid connection assembly is also filled with a filling piece 2, which can avoid leakage caused by the filling piece 2 being squeezed out or torn as much as possible.
[0054] Furthermore, if Figure 1 and Figure 2 As shown, one end of the second connector 4 is fixed to the inner wall of one of the linings, and the other end extends toward the segment lining 1 on the other side of the structural joint and exceeds the structural joint, so that the second connector 4 can cover the structural joint and avoid leakage at the structural joint as much as possible.
[0055] Furthermore, if Figure 1 and Figure 2 As shown, the first connector 3 is provided with a connecting portion and an overlapping portion, the connecting portion is used to connect the inner wall of the segment lining 1, the overlapping portion is used to overlap the second connector 4, the overlapping portion extends to the segment lining 1 on the other side of the corresponding structural seam, and the connecting portion and the overlapping portion are located in two planes. In this embodiment, the connecting portion and the overlapping portion are respectively located in two planes perpendicular to the radial direction of the chamber. The overlapping portion and the connecting portion are respectively located in two planes, which is convenient for overlapping the second connecting portion and also convenient for setting the filling member 2 at the overlapping position.
[0056] Furthermore, if Figure 2 As shown, the segment lining 1 is provided with an embedded steel plate 5. The first connector 3 and the second connector 4 are both welded to the embedded steel plate 5. This connection method can also be replaced by: Figure 1 As shown, the first connecting member 3 and the second connecting member 4 are provided with screw holes, and the bolts 6 pass through the screw holes and extend into the inner wall of the segment lining 1.
[0057] The structural joint between two adjacent segment linings 1 is provided with a shear member. The shear member can be a shear key, a shear pin 7 or a shear nail, etc. The shear member is provided between two adjacent segment linings 1 to avoid the misalignment of the two adjacent segment linings 1 as much as possible, which affects the structural stability of the chamber. In this embodiment, if Figure 1 and Figure 2 As shown, the shear-resistant member is a shear pin 7, and both ends of the shear pin 7 are anchored to the side walls of two adjacent segment linings 1 respectively.
[0058] It also includes a fixing steel bar 8, which extends into the side wall of the segment lining 1 toward the structural joint, and is used to fix the shear pin 7. In this embodiment, Figure 3 and Figure 4 As shown, two fixing steel bars 8 are arranged on one side of a segment lining 1, and the two fixing steel bars 8 fix the shear pin 7 from above and below the shear pin 7 respectively. One shear pin 7 needs to be fixed by four fixing steel bars 8, which is beneficial to improving the stability of the structure.
[0059] Example 2
[0060] A gas storage chamber, characterized in that it includes a concrete lining joint sealing structure as described in Example 1, which can absorb the deformation of the chamber concrete segment lining caused by the circumferential stress and avoid the cracking and misalignment of the segment lining as much as possible. A steel plate sealing layer connected by a rigid connector is arranged on the inner side of the lining. The rigid connection assembly can make the steel plate sealing layer adapt to large deformation, reduce the circumferential tensile stress of the steel lining sealing layer, thereby thinning the thickness of the steel lining sealing layer, which is conducive to reducing the construction cost. Combined with the block-type concrete segment lining 1, it can effectively prevent the thin steel plate sealing layer from being damaged due to being pressed into the lining cracks and causing gas leakage. In addition, the overlap design of the rigid connection assembly at the structural seam of the concrete lining segment has a limiting effect on the filling piece 2 between the two segment linings 1 to avoid being squeezed out. And the overlap of the rigid connection assembly is also filled with the filling piece 2, so that leakage caused by the filling piece 2 being squeezed out or torn can be avoided as much as possible.
