Description

Technical Field

[0001] The utility model relates to the technical field of gravity energy storage equipment, in particular to a gravity energy storage underground space building template. Background Art

[0002] Gravity energy storage technology refers to the vertical lifting movement of heavy objects from underground under the action of a driving motor through the traction of a steel wire rope, thereby completing the conversion between gravitational potential energy and electrical energy. Gravity energy storage equipment is composed of multiple energy storage units. An energy storage unit usually mainly includes a group of heavy objects, a drive generator and a well site mined on the ground. During the construction of the well site, a building template needs to be placed in the well and fit to the inner wall of the well, and concrete is injected into the gap between the building template and the inner wall of the well. After the concrete solidifies, the well site construction is completed.

[0003] In order to prevent the building formwork from being compressed and deformed during the concrete pouring process, traditional building formwork is generally made of hard materials such as steel, wood or plastic. For the convenience of installation, the hard building formwork needs to be divided into several sections and lowered into the well in turn. After the concrete is solidified and formed, some of the building formwork needs to be taken out of the well. The previous and subsequent construction processes are time-consuming and labor-intensive, which not only affects the construction efficiency, but also wastes manpower and material resources, making the construction cost of the well site higher.

[0004] Therefore, it is necessary to propose a gravity energy storage underground space building template to improve construction efficiency while reducing the construction cost of the well site. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the existing building template affects the construction efficiency of the well site and makes the construction cost of the well site higher. A gravity energy storage underground space building template is now provided.

[0006] The technical solution of the utility model is:

[0007] A gravity energy storage underground space building template comprises a support frame and a building template surrounded by an air film, wherein the building template is a hollow structure with openings at both ends, and comprises a first template and a second template, wherein the bottom end of the first template is fixedly connected to the top end of the second template, and the bottom end of the second template is fixedly connected to the support frame, the diameter of the first template is smaller than the diameter of the support frame, and the diameter of the support frame matches the diameter of the well site, and the air film can be filled with a filler.

[0008] Furthermore, the second template includes a transition template and a support template, the diameter of the support template matches the diameter of the support frame, the bottom end of the support template is fixedly connected to the support frame, one end of the transition template is fixedly connected to the first template, and the other end is fixedly connected to the support template.

[0009] Furthermore, the transition template is in the shape of a truncated cone, the diameter of the top end of which is the same as the diameter of the first template, and the diameter of the bottom end of the transition template is the same as the diameter of the supporting template.

[0010] Furthermore, a positioning seat is provided at the bottom of the support frame, and the center of the positioning seat coincides with the axis of the support frame.

[0011] Furthermore, the positioning seat is cylindrical.

[0012] Furthermore, a connecting rod is provided between the support frame and the positioning seat, one end of the connecting rod is fixedly connected to the support frame, and the other end of the connecting rod is fixedly connected to the positioning seat.

[0013] Furthermore, the filler in the air film is gas.

[0014] Furthermore, the transition template is in the shape of a truncated cone with a top diameter smaller than a bottom diameter.

[0015] Furthermore, the support template is a cylinder with a top diameter equal to a bottom diameter.

[0016] Furthermore, the first template is cylindrical with a top diameter equal to a bottom diameter.

[0017] The utility model discloses a gravity energy storage underground space building formwork, wherein the support frame is located at the end of the air film, and the air film is initially rolled up on a reel, similar to the storage method of cloth, and when the support frame is installed on the air film, the support frame is lowered into the well, and the support frame can sink to the bottom of the well by its own weight, and the air film will also follow the support frame into the well, and when the support frame falls into the well bottom and is stable, the support frame at the well mouth end and the well bottom is tightened, so that the air film is propped up to form a cylindrical building formwork surrounding the well wall around the well, and by injecting concrete slurry and other building materials into the hollow structure, the heavier concrete slurry will enter the well bottom, and the support frame can be wrapped and covered, and the support frame can be cast and fixed to the well bottom after solidification, and the concrete slurry continues to be cast to fill the hollow structure of the second formwork until it reaches the junction of the first formwork and the second formwork, and the casting is stopped, and then the filler is filled into the air film to make the air film swell, thereby increasing the pressure on the air film, and then concrete is cast into the gap between the building formwork and the well wall. The concrete slurry is poured into the wellhead until it reaches the wellhead. At this time, the pouring is completed. After the concrete solidifies, the well site can be constructed. If there is water in the well bottom and the concrete slurry is heavy, it will squeeze the water at the well bottom upward while sinking to the well bottom, and then the water above the concrete will be pumped out. Under the gravity of the support frame, the air film can be easily tightened and propped up. When pouring the support frame and the second formwork, the air film formwork will not be squeezed and deformed by the concrete, and the bottom diameter of the second formwork is larger than its top diameter. The concrete slurry poured in the second formwork is less likely to squeeze and deform the second formwork. After the air film is filled with fillers, the pressure resistance of the air film formwork will be increased. At this time, the concrete slurry poured into the gap between the well wall and the air film formwork will not deform the first formwork. Finally, the well site constructed fully meets the construction requirements. Compared with the traditional technology, the technical solution adopts the air film to be directly lowered into the well, replacing the cumbersome steps of the traditional construction formwork to be installed in sections into the well, which not only improves the construction efficiency, but also saves manpower and material resources, and reduces the construction cost of the well site.

[0029] Preferably, the transition template 7 is in a truncated cone shape, the diameter of the top end of which is the same as the diameter of the first template 3 , and the diameter of the bottom end of the transition template 7 is the same as the diameter of the supporting template 8 .

[0030] Preferably, Figure 3 , Figure 4 and Figure 5As shown, a positioning seat 9 is provided at the bottom of the support frame 1, and the center of the positioning seat 9 coincides with the axis of the support frame 1. The support frame 1 is annular, and the positioning seat 9 is located at the center directly below the support frame 1. When the support frame 1 falls into the bottom of the well, the positioning seat 9 first contacts the bottom of the well, and because the diameter of the support frame 1 is the same as or matches the diameter of the well position 6, the center of the positioning seat 9 will coincide with the center of the circle of the bottom of the well, which can assist the support frame 1 in being fixed at the bottom of the well to improve stability, and on the other hand, it can assist the support frame 1 in automatically centering the bottom circle of the well, so that the support frame 1 is coaxial with the bottom of the well. , or the gaps around the support frame 1 and the well wall are the same, and the support frame 1 is located at the center of the well, so that after the building template 2 falls into the well and opens, it will also be located at the center of the well, and the building template 2 is coaxial with the well, so that the gaps around the building template 2 and the well wall are equal, ensuring the construction accuracy of the well position 6 after pouring concrete. Preferably, the positioning seat 9 is cylindrical. Preferably, a connecting rod 10 is provided between the support frame 1 and the positioning seat 9, one end of the connecting rod 10 is connected to the support frame 1 by screws or welding, and the other end of the connecting rod 10 is connected to the positioning seat 9 by screws or welding.

[0031] Preferably, the filler in the air membrane 5 is gas, and the gas of the filler can be air, or other gases such as nitrogen or carbon dioxide, preferably air. The air pressure of the gas filled in the air membrane 5 is preferably 3Mpa. The specific construction air pressure can be determined by technical personnel in this field according to factors such as the depth of the well and the amount of concrete poured.

[0032] Preferably, the transition template 7 is in the shape of a truncated cone with a top diameter smaller than a bottom diameter.

[0033] Preferably, the support template 8 is cylindrical with a top diameter equal to a bottom diameter.

[0034] Preferably, the first template 3 is cylindrical with a top diameter equal to a bottom diameter.

[0035] The specific construction steps are:

[0036] 1. Use a drilling machine to dig a deep well on the ground to form a well-shaped underground space, referred to as well location 6. If the well depth reaches the groundwater level, there is water at the bottom of the well.

[0037] 2. The air film 5 is made of flexible materials such as PVC and is rolled up at the wellhead. After the impurities in the well are cleared, the support frame 1, the positioning seat 9 and the connecting rod 10 thereon are first placed into the bottom of the well. The support frame 1, the positioning seat 9 and the connecting rod 10 thereon are made of heavy medium materials. Under the action of their own gravity, the support frame 1, the positioning seat 9 and the connecting rod 10 thereon quickly reach the bottom of the well, and the building template 2 is driven by the three to quickly penetrate the well position 6 and reach the bottom of the well.

[0038] 3. Send the grouting pipe into the hollow structure 12 of the building template 2 and reach the bottom of the well to start pouring cement. The cement flows to the bottom of the well through the gap between the support frame 1 and the connecting rod 10. After filling the bottom of the well, the support template 8 is filled, and finally the transition template 7 is filled. After the bell mouth of the air film 5 template is filled with cement, the entire building template 2 is vertically located in the middle of the well position 6. At this time, concrete slurry is no longer poured into the hollow structure 12 of the building template 2. The grouting pipe is retracted to the ground. At this time, the bottom of the cavity of the air film 5 template is cement, and the upper part is water.

[0039] 4. After the concrete slurry in the hollow structure 12 in the building template 2 solidifies, inject gas of appropriate pressure into the air membrane 5, and the air membrane 5 filled with gas expands. Since the hollow structure 12 in the second template 4 is already filled with concrete and solidified at this time, the injected gas will only be in the air membrane 5 of the first template 3. The air membrane 5 of the first template 3 expands into a cylindrical shape, which is the same as the well shape. The inflation port also enhances the air membrane 5's ability to resist extrusion deformation.

[0040] 5. At the wellhead, if Figure 6 As shown, four points A, B, C, and D are selected between the building formwork 2 and the wall of the well 6 as the wellhead 11 for pouring the deep groove, and four grouting pipes are simultaneously sent into the bottom of the well from the four points A, B, C, and D of the cement pouring deep groove wellhead 11. After all four grouting pipe openings reach the bottom of the well, concrete pumping begins. At this time, the original water body of the pouring deep groove is replaced by concrete slurry from the bottom to the top, and water is pressed out from the wellhead. According to the concrete pumping volume and pumping progress, the four grouting pipes are raised from the wellhead 11 for pouring the deep groove in real time to complete the pouring of the concrete slurry. After the four grouting pipes are slowly raised, the slurry surface of the concrete slurry in the wellhead 11 for pouring the deep groove will sink a little. At this time, concrete slurry is poured at the top again until the concrete slurry is flush with the ground, and the pouring is ended.

[0041] 6. If Figure 7 As shown, after the deep groove well 11 is filled with concrete slurry, a concrete circular tube 13 is formed, and the concrete circular tube 13 enters the natural curing period. At this time, the hollow structure 12 of the second template 4 is filled with solidified concrete or cement, and the upper part of the second template 4 or the hollow structure 12 of the first template 3 is filled with water.

[0042] 7. When the concrete circular tube 13 reaches the designed strength, the water in the hollow structure 12 of the first template 3 is pumped out, and the construction of the well-shaped underground space is completed.

[0043] The support frame 1 is located at the end of the air film 5. In the initial state, the air film 5 exists by being rolled up on a reel, which is similar to the storage method of cloth. When the support frame 1 is installed on the air film 5, the support frame 1 is lowered into the well. The support frame 1 can sink to the bottom of the well by its own weight, and the air film 5 will also fall into the well with the supported frame 1. When the support frame 1 falls to the bottom of the well and stabilizes, the positioning seat 9 will fall at the center of the well bottom circle. The support frame 1 is located directly above the positioning seat 9 and remains horizontal. Due to the material of the support frame 1, its weight is huge. The end of the air film 5 at the wellhead can cooperate with the support frame 1 at the bottom of the well to tighten the air film 5, so that the air film 5 is The well is supported to form a cylindrical building template 2 surrounding the well wall, and then a grouting pipe is extended from the middle of the building template 2. The grouting pipe passes through the hollow structure 12 of the building template 2, and the grouting pipe mouth reaches the bottom of the well. At a distance of 30-50 cm from the bottom of the well, concrete slurry and other building materials are injected into the bottom of the well. The heavier concrete slurry will enter the bottom of the well. If there is water at the bottom of the well at this time, the water can be squeezed out and raised. After that, the support frame 1 is wrapped and covered with concrete slurry. After solidification, the support frame 1 can be cast and fixed at the bottom of the well, and the concrete slurry is continued to be poured to fill the hollow structure 12 of the second template 4 until it reaches the first template 3 and the second template 4. At the junction of the plates 4, the pouring is stopped, and then the filler is filled into the air film 5 to make the air film 5 bulge, thereby increasing the pressure on the air film 5, and then concrete slurry is poured into the gap between the building formwork 2 and the well wall until the concrete slurry reaches the wellhead. At this time, the pouring is completed, and the construction of the well position 6 can be completed after the concrete solidifies. If there is water at the bottom of the well, the concrete slurry is heavy, and when it sinks to the bottom of the well, it will squeeze the water at the bottom of the well upward, and then the water above the concrete will be pumped out. Under the gravity of the support frame 1, the air film 5 is easily tightened and supported. When pouring the support frame 1 and the second formwork 4, the air film 5 formwork will not be squeezed and deformed by the concrete. , and the bottom diameter of the second template 4 is larger than its top diameter, the concrete slurry poured in the second template 4 is less likely to squeeze and deform the second template 4, and after the air film 5 is filled with fillers, the pressure resistance of the air film 5 template will be improved. At this time, the concrete slurry poured into the gap between the well wall and the air film 5 template will not deform the first template 3. Finally, the well site 6 constructed fully meets the construction requirements. Compared with the traditional technology, the technical solution adopts the air film 5 to be directly lowered into the well, replacing the cumbersome steps of the traditional building template 2 to be installed in sections into the well, which not only improves the construction efficiency, but also saves manpower and material resources, and reduces the construction cost of the well site 6.

[0044] Preferably, the pumped concrete slurry can also be replaced by cement, and the specific building materials can be determined according to the specific construction conditions.
