Description

Technical Field

[0001] The present invention relates to the technical field of underground compressed air energy storage, and particularly to an integrated waterproof and seismic isolation structure for underground compressed air energy storage and a construction method thereof. Background Technique

[0002] At present, gas storage and energy storage have become important measures to ensure China's energy security and promote the development of new energy. In particular, building gas storage caverns using underground space will be the key development direction of the energy storage industry in the future. However, the construction of compressed air energy storage is still in its initial stage, and there are still a series of problems such as insufficient airtightness of gas storage caverns, groundwater in surrounding rocks eroding the reinforced concrete lining layer, and facilities in seismic areas being prone to damage. For example, the patent with the publication number CN116624223A discloses a sealing structure for an underground gas storage cavern of compressed air energy storage and a manufacturing method thereof. Although it is provided with a steel bar layer to resist the tensile failure caused by the expansion of concrete under high pressure, for the underground compressed air energy storage structure, the problem of structural damage caused by vibration is not considered, and thus the stability and durability of the sealing structure are affected. Moreover, for the external pressure, the fissure water or groundwater on the periphery cannot be drained away. When exhausting gas, a huge pressure difference is generated between the inside and outside, which is likely to cause damage to the structure.

[0003] Therefore, the present invention provides an integrated waterproof and seismic isolation structure for underground compressed air energy storage and a construction method thereof. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an integrated waterproof and seismic isolation structure for underground compressed air energy storage and a construction method thereof to solve the problems raised in the above background technique. The present invention can seep water through the external support, collect the infiltrated water through the water collection cavity, and then discharge it into the drainage well. The water can be pumped out when exhausting gas or when there is more water, so that the water level can be adjusted, and thus the pressure can be adjusted. It can achieve a good seismic isolation effect, prevent air leakage caused by vibration, and extend the service life of the device. It can ensure a good sealing effect and extend the service life of the device. It can drive the internal support to move a certain distance, which can not only shake off the accumulated water droplets on the external support, but also clean the inside of the water collection cavity to prevent the water outlet from being blocked and ensure the drainage effect of the device.

Specific embodiments

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figures 1 to 12 , the present invention provides a technical solution: an integrated waterproof and seismic isolation structure for underground compressed air energy storage, including a drainage structure, a seismic isolation structure, a support structure and an energy storage structure. The drainage structure includes a plurality of drainage wells 1. The support structure includes an external support 3 and a plurality of internal supports 11. A water collection chamber 6 is opened at the bottom of the external support 3. The water collection chamber 6 corresponds to the drainage well 1. A support structure is installed between the external support 3 and the internal support 11. The energy storage structure includes an outer lining 19 and an inner lining 20. A concrete layer 21 and an asphalt layer 22 are installed between the outer lining 19 and the inner lining 20. A buffer structure is installed on the periphery of the outer lining 19. The buffer structure corresponds to the internal support 11. A buffer gap is installed between the internal support 11 and the outer lining 19. A plurality of connection structures are installed on the periphery of the outer lining 19. The connection structures correspond to the internal support 11. The support structure further includes a fixed seat 10 and an electric slide rail 23. The fixed seat 10 corresponds to the electric slide rail 23. The fixed seat 10 corresponds to the internal support 11. Both the internal support 11 and the buffer structure correspond to the water collection chamber 6.

[0020] In this embodiment, a connecting pipe 2 is installed between the water collection chamber 6 and the drainage well 1. For the connecting pipe 2, a plurality of drainage wells 1 are respectively located on both sides of the external support 3. A plurality of water outlets 7 are opened in the water collection chamber 6. Both ends of the connecting pipe 2 are respectively communicated with the water outlet 7 and the drainage well 1. The connecting pipe 2 is of an inclined downward structure.

[0021] Specifically, the water in the water collecting cavity 6 can be diverted into the drainage well 1 through the connecting pipe 2. The groundwater or fissure water collected in the water collecting cavity 6 enters the connecting pipe 2 through the water outlet 7. Due to the downward-sloping structure of the connecting pipe 2, the water flows downward under the action of gravity and thus enters the drainage well 1. When the water level in the drainage well 1 reaches a certain height, a water pump can be installed externally to pump water, thereby reducing the water level, reducing the pressure on the external support 3, and preventing the external support 3 from being damaged by excessive pressure, ensuring the support and protection effects of the external support 3.

[0022] The top of the external support 3 is an arc-shaped structure. A plurality of water seepage holes 5 are provided on the peripheral side of the external support 3. A plurality of expansion joints 4 are provided on the external support 3. The relative inner side of the external support 3 is a rough surface structure. The support structure corresponds to the rough surface structure and is in contact with the relative inner side of the external support 3.

[0023] Specifically, the arc-shaped structure can disperse the pressure, thereby achieving a better support effect and preventing collapse, and can withstand greater pressure. Water seepage can be carried out through the water seepage holes 5, facilitating the inflow of groundwater or fissure water into the water collecting cavity 6 for drainage, thus reducing the water level and pressure. Moreover, the expansion of the external support 3 can be buffered through the expansion joints 4, preventing cracks from occurring in the external support 3 due to thermal expansion and affecting the structural strength.

[0024] The inner support 11 includes a first guard plate 12 and a second guard plate 13. The buffer structure corresponds to the first guard plate 12 and the second guard plate 13. A fixing block 28 is installed between the first guard plate 12 and the second guard plate 13. The fixing block 28 corresponds to the buffer structure. The second guard plate 13 corresponds to the connecting structure. The support structure includes a triangular support plate 15. The end of the triangular support plate 15 is a rough surface structure. The end of the triangular support plate 15 is in contact with the relative inner side of the external support 3. A connecting plate 14 is fixed between two adjacent inner supports 11.

[0025] Specifically, the inner support 11 can be used for auxiliary support. A part of the force received by the external support 3 is transmitted to the inner support 11 through the triangular support plate 15 to assist the external support 3 in supporting. Moreover, due to water seepage, a large amount of water droplets will remain on the inner surface of the external support 3. The inner support 11 is a movable structure. As the inner support 11 moves, the two rough surface structures come into contact, generating slight vibrations, causing the water to vibrate and fall into the water collecting cavity 6.

[0026] And the buffer structure is located between the first protective plate 12 and the second protective plate 13. Thus, the buffer structure can be limited by the first protective plate 12 and the second protective plate 13. Moreover, the pressure received by the outer support 3 is transmitted to the first protective plate 12 through the triangular support plate 15, and then transmitted to the second protective plate 13 through the fixing block 28 between the first protective plate 12 and the second protective plate 13. At this time, there is a gap between the buffer structure and the first protective plate 12 and the second protective plate 13. Therefore, the pressure will not be transmitted to the buffer structure, nor will it be transmitted to the outer lining layer 19. At this time, the support structure and the energy storage structure are relatively independent. Therefore, the energy storage structure does not need to bear the external pressure.

[0027] The buffer structure includes a buffer plate 16. A plurality of first shock isolation supports 9 are fixed between the buffer plate 16 and the outer lining layer 19. The buffer plate 16 is located between the first protective plate 12 and the second protective plate 13. A plurality of through grooves 17 are formed in the buffer plate 16, and the through grooves 17 correspond to the fixing blocks 28. The shock isolation structure includes a plurality of shock isolation balls 8 and a plurality of second shock isolation supports 18. The second shock isolation supports 18 are fixedly connected to the outer lining layer 19. The bottom of the outer lining layer 19 is a planar structure. The shock isolation balls 8 are located below the outer lining layer 19, and the second shock isolation supports 18 and the shock isolation balls 8 are arranged at intervals.

[0028] Specifically, when vibrations occur, at this time, the second shock isolation supports 18 and the shock isolation balls 8 can achieve a good shock isolation effect. At the same time, the buffer plate 16 can be limited by the first protective plate 12 and the second protective plate 13, and shock isolation is carried out through the first shock isolation supports 9, so as to ensure the overall shock isolation effect of the gas storage structure and prevent the gas storage structure from leaking air.

[0029] The connection structure includes a plurality of upper connection blocks 24. The upper connection blocks 24 are fixedly connected to the outer lining layer 19. The upper connection blocks 24 correspond to the second protective plates 13. The upper connection blocks 24 are located between two adjacent second protective plates 13, and the upper surfaces of the upper connection blocks 24 and the relative inner sides of the second protective plates 13 are on the same plane. The connection structure further includes a plurality of lower connection blocks 25. The lower connection blocks 25 are fixedly connected to the outer lining layer 19. The fixing seat 10 is located between two adjacent lower connection blocks 25, and the upper surface of the fixing seat 10 and the lower surface of the lower connection blocks 25 are on the same plane. The fixing seat 10 is fixedly connected to the output end of the electric slide rail 23.

[0030] Specifically, when the inner support 11 moves, at this time, the second protective plate 13 moves until the second protective plate 13 contacts the upper connection block 24. At the same time, the fixing seat 10 contacts the lower connection block 25. At this time, the force received by the second protective plate 13 can be transmitted to the outer lining layer 19, so as to assist in supporting through the gas storage structure and ensure the support effect of the device.

[0031] Start the electric slide rail 23, and the fixed seat 10 can be driven to slide by the electric slide rail 23, thereby driving the first guard plate 12 and the second guard plate 13 to slide, so as to conveniently adjust the relative position between the second guard plate 13 and the upper connecting block 24, and thus auxiliary support can be carried out through the air storage structure according to requirements.

[0032] The inner support 11 and the buffer structure are both located on the upper side of the water collection cavity 6. A brush block 27 is fixed on one side of the fixed seat 10. The brush block 27 is located in the water collection cavity 6, and the fixed seat 10 is fixedly connected to the first guard plate 12 and the second guard plate 13.

[0033] Specifically, as the inner support 11 moves, the inner support 11 drives the brush block 27 to move together, thereby brushing the sundries in the water collection cavity 6 and brushing the sundries above the water outlet 7 to one side, so as to prevent the water outlet 7 from being blocked.

[0034] Working process: Water seeps through the seepage holes 5, so as to facilitate the inflow of groundwater or fissure water into the water collection cavity 6. The expansion of the outer support 3 can be buffered through the expansion joint 4. The connecting pipe 2 diverts the water in the water collection cavity 6 into the drainage well 1. The groundwater or fissure water collected in the water collection cavity 6 enters the connecting pipe 2 through the water outlet 7. Due to the downward-sloping structure of the connecting pipe 2, the water flows downward under the action of gravity and thus enters the drainage well 1. When the water level in the drainage well 1 reaches a certain height, a water pump can be installed externally to pump water, thereby reducing the water level; Support is carried out through the outer support 3, auxiliary support is carried out through the inner support 11, and a part of the force received by the outer support 3 is transmitted to the inner support 11 through the triangular support plate 15, thereby assisting the outer support 3 in supporting. Start the electric slide rail 23, and the fixed seat 10 can be driven to slide by the electric slide rail 23, thereby driving the first guard plate 12 and the second guard plate 13 to slide. As the inner support 11 moves, the two rough surface structures come into contact, and slight vibrations can be generated, so that the water vibrates and falls into the water collection cavity 6. At the same time, the second guard plate 13 contacts the upper connecting block 24, and the fixed seat 10 contacts the lower connecting block 25. At this time, the force received by the second guard plate 13 can be transmitted to the outer lining 19, so as to assist in supporting through the air storage structure and ensure the supporting effect of the device; The second shock isolation support 18 and the shock isolation ball 8 can achieve a good shock isolation effect. At the same time, the buffer plate 16 can be limited by the first guard plate 12 and the second guard plate 13, and shock isolation is carried out through the first shock isolation support 9, so as to ensure the overall shock isolation effect of the air storage structure and prevent the air storage structure from leaking air.

[0035] A construction method for an integrated underground compressed air energy storage waterproof and shock isolation structure includes the following steps: S1. Excavate the construction space through a roadheader and fix the outer support on the side of the space for protection; S2. Install a drainage structure at the bottom of the external support. Excavate a drainage well with a roadheader, connect the drainage structure to the drainage well, and let the seepage water of the external support flow into the drainage structure and then into the drainage well, so as to facilitate pumping out the water in the drainage well for pressure balance; S3. Install seismic isolation bearings, seismic isolation balls and a support structure at the bottom of the construction space. Use the support structure to assist the external support for protection to increase the compressive capacity, and use the seismic isolation bearings and seismic isolation balls to increase the seismic capacity. Install an electric slide rail at the bottom of the construction space, and drive the support structure to move through the electric slide rail to disperse the pressure and clean the drainage structure; S4. Install a buffer layer on the periphery of the outer lining layer to assist in seismic isolation and at the same time assist the external support and the support structure for support; S5. Arrange a concrete layer, an asphalt layer and an inner lining layer in the outer lining layer. A gas storage space is formed on the relative inner side of the inner lining layer. The concrete layer and the asphalt layer are used for waterproofing, and the asphalt layer is used for buffering and shock absorption.

[0036] Workflow: Excavate the construction space and the drainage well with a roadheader, fix the external support on the side of the space for support, let the external support seep water by itself, and discharge the water into the drainage well through the drainage structure, so as to facilitate pumping out the water to adjust the water level and thus reduce the pressure on the external support.

[0037] Install seismic isolation bearings, seismic isolation balls, an electric slide rail and a support structure at the bottom of the construction space. Seismic isolation can be carried out through the seismic isolation bearings and seismic isolation balls, and the support structure can be driven to move through the electric slide rail, so as to adjust the structure of the device, and thus the outer support 3 can be assisted in support by the outer lining layer to ensure the strength of the device.

[0038] The concrete layer and the asphalt layer can achieve a good waterproof effect, and the asphalt layer can be used for buffering. The asphalt layer has a good shock absorption effect and can assist in shock absorption to ensure sealing.

The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

10. The construction method of an integrated underground compressed air energy storage waterproof and shock isolation structure according to claim 1, characterized in that: It includes the following steps: S1. Excavate the construction space by a roadheader, and fix the outer support on the side of the space for protection. S2. Install the drainage structure at the bottom of the outer support. Dig a drainage well by the roadheader, connect the drainage structure with the drainage well. Let the water seeped through the outer support flow into the drainage structure and then into the drainage well, so as to facilitate pumping out the water in the drainage well to balance the pressure. S3. Install shock isolation supports, shock isolation balls and a support structure at the bottom of the construction space. Use the support structure to assist the outer support for protection and increase the compressive capacity. Use the shock isolation supports and shock isolation balls to increase the seismic capacity. Install an electric slide rail at the bottom of the construction space. Drive the support structure to move through the electric slide rail to disperse the pressure and clean the drainage structure. S4. Install a buffer layer on the periphery of the outer lining layer to assist in shock isolation and at the same time assist the outer support and the support structure for support. S5. Set a concrete layer, an asphalt layer and a lining layer in the outer lining layer. An air storage space is formed on the relative inner sides of the lining layer. Use the concrete layer and the asphalt layer for waterproofing, and use the asphalt layer for buffering and shock absorption.
