Description

Technical Field

[0001] The invention belongs to the technical field of drainage, and specifically relates to an auxiliary system for drainage risks in deep underground space development. Background Technique

[0002] With the rapid development of urbanization in China, urban renewal has become the key development direction in the core areas of super-large cities such as Shanghai. The development of urban underground space has been rapidly advancing towards digitalization, industrialization, large-scale, energy-saving and high-efficiency directions. When developing deep underground space under existing large industrial buildings, the foundation form and stress state of the existing buildings are changed. Whether the upper structure of the existing buildings is safe has become a key issue during this process.

[0003] When constructing additional underground space in existing buildings, aspects such as pile foundation enclosure construction, foundation pit water stop and dewatering, and foundation pit deformation need to be considered. When dewatering the foundation pit, workers can use equipment such as water pumps to drain some of the water sources inside the foundation pit to ensure the construction environment. However, during this process, a large amount of drainage may affect the environment around the foundation pit due to water pressure changes, resulting in situations such as deformation of the pile foundation enclosures used to support the existing buildings inside the foundation pit, thus affecting the support effect on the existing buildings. And due to the large construction site, it is difficult for workers to promptly detect slight deformations in a certain enclosure, which affects the safe operation of deep underground space development.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Such as Figures 1 to 11As shown in the figure, the present invention provides an auxiliary system for drainage risk in deep underground space development, including a base 1 and a water pump 26 installed on the top of the base 1. A support 2 and a fixed frame 16 are fixed on the top of the base 1. A hollow box 3 is fixed on the top of the support 2. An extrusion mechanism 4 is arranged inside the hollow box 3. Air bags 5 are fixed on both sides of the inner wall of the hollow box 3. The extrusion mechanism 4 can extrude the air bags 5 and squeeze out the gas inside the air bags 5. Lower pressing plates 7 slide through both sides of the top of the hollow box 3. The lower pressing plates 7 cooperate with the extrusion mechanism 4 to squeeze the air bags 5. A water storage tank 8 is fixed on the top of the lower pressing plates 7. A cross plate 9 is arranged on the top of the water storage tank 8 and an inner plate 12 slides through it. A support plate is fixed on the inner wall of the water storage tank 8. The bottom of the inner plate 12 contacts the top of the support plate. When the inner plate 12 is idle, the support plate supports and limits the inner plate 12. A first limiting mechanism 13 is installed on the surface of the water storage tank 8. The first limiting mechanism 13 includes an outer frame 131 fixed on the surface of the water storage tank 8, a first limiting plate 132 fixed on the bottom of the cross plate 9, and a first auxiliary component 133 arranged inside the outer frame 131. Second limiting mechanisms 14 are installed on the surfaces of both sides of the water storage tank 8. The second limiting mechanisms 14 include second limiting plates 141 fixed on the surface of the water storage tank 8, sliding frames 142 fixed on the surface of the hollow box 3, elastic pieces 144 installed on the inner walls of the sliding frames 142, and second auxiliary components 143 arranged inside the sliding frames 142. A buffer pad 15 is fixed on the bottom of the water storage tank 8. The setting of the buffer pad 15 can reduce the hard contact between the bottom of the water storage tank 8 and the top of the hollow box 3; An air injection box 17 is fixed on the surface of the fixed frame 16. A ventilation pipe 18 is communicated with the surface of the air injection box 17. The two ends of the ventilation pipe 18 are respectively communicated with the two air bags 5. A moving mechanism 19 is installed inside the air injection box 17. An arc plate 20 is slidably connected to the inner wall of the fixed frame 16. An inclined plate 21 is fixed on the top of the arc plate 20. Lifting mechanisms 22 are installed on both sides of the top of the base 1. Side plates 23 are fixed on the surfaces of both sides of the cross plate 9. A stress plate 24 is fixed on the surface of the side plates 23. The lifting mechanisms 22 cooperate with the stress plate 24 and the side plates 23 to adjust the height of the cross plate 9 so that the cross plate 9 can lift to support the deformed existing building pile foundation enclosure. A sealing mechanism 25 is installed on the surface of the arc plate 20. The water outlet of the water pump 26 is communicated with a water outlet pipe 27. The top of the water outlet pipe 27 is communicated with a water delivery pipe 28 communicated with the water storage tank 8. The bottom of the water outlet pipe 27 is communicated with a drain pipe 29. The water inlet of the water pump 26 is communicated with a water inlet pipe. When the staff starts the water pump 26, the water inlet pipe can pump out part of the water source in the foundation pit, thereby reducing the influence of excessive water source on the construction.

[0022] As Figure 2 - Figure 4As shown in the figure, the extrusion mechanism 4 includes a smooth rod 41, an extrusion plate 42 and a first compression spring 43. Both ends of the smooth rod 41 are fixed to both sides of the inner wall of the hollow box 3. The number of extrusion plates 42 is two, and the two extrusion plates 42 are respectively slidably sleeved on both sides of the surface of the smooth rod 41. The first compression spring 43 is sleeved on the surface of the smooth rod 41. The surface of the extrusion plate 42 is fixed to the surface of the airbag 5. The bottom of the lower pressing plate 7 is slidably connected to the top of the extrusion plate 42. When the cross plate 9 is stressed, the pressure is transmitted to the water storage tank 8. At this time, the lower pressing plate 7 descends with the water storage tank 8 and can extrude the extrusion plate 42. The extrusion plate 42 moves and extrudes the airbag 5. The gas inside the airbag 5 is discharged into the inside of the air injection box 17 through the air pipe 18. When the extrusion plate 42 moves, the smooth rod 41 guides the movement of the extrusion plate 42.

[0023] A partition plate 6 is fixed to the bottom of the extrusion plate 42. The bottom of the airbag 5 is in contact with the top of the partition plate 6. Through the arrangement of the partition plate 6, the airbag 5 can be isolated from the first compression spring 43, increasing the practicability of the airbag 5.

[0024] Guide plates 11 are fixed to the surfaces of the other two sides of the cross plate 9. On the top of the base 1 and on both sides of the support 2, guide frames 10 are fixed. The guide plates 11 slidably penetrate through the top of the guide frames 10. Through the cooperation of the guide frames 10 and the guide plates 11, the stability of the lifting movement of the cross plate 9 can be increased.

[0025] Adopting the above solution: When the drainage operation affects the stability of the retaining support, the retaining structure deforms and presses down on the cross plate 9. The cross plate 9 supports the retaining structure. The water storage tank 8 is stressed and drives the lower pressing plate 7 to descend. The extrusion plate 42 is extruded by the lower pressing plate 7 and moves, and the air inside the airbag 5 is discharged into the inside of the air injection box 17 through the air pipe 18, so as to move the moving mechanism 19 inside the air injection box 17 through air pressure.

[0026] As Figure 8 - Figure 11 As shown in the figure, the first auxiliary component 133 includes a connecting frame 1331, a first auxiliary plate 1332 and a second compression spring 1333. The connecting frame 1331 slidably penetrates through the surface of the outer frame 131. The first auxiliary plate 1332 is fixed to one end of the connecting frame 1331. The second compression spring 1333 is sleeved on the surface of the connecting frame 1331. The surface of the first limiting plate 132 is in contact with both the inner wall of the outer frame 131 and the surface of the first auxiliary plate 1332. The surface of the first auxiliary plate 1332 is slidably connected to the inner wall of the outer frame 131.

[0027] Adopting the above solution: when the cross plate 9 descends, the first limiting plate 132 presses down the first auxiliary plate 1332, and the water storage tank 8 descends accordingly. When the cross plate 9 ascends, the first limiting plate 132 ascends accordingly. During this process, the second compression spring 1333 moves under the extrusion of the first auxiliary plate 1332. At this time, the second compression spring 1333 is stressed and shortened. After that, under the elastic force of the second compression spring 1333, the first auxiliary plate 1332 moves back to its original position and cooperates with the first limiting plate 132 to reinforce the position of the first limiting plate 132, thereby restricting the descending height of the cross plate 9. At this time, the lifted cross plate 9 can stably support the upper enclosure, thereby reducing the harm caused by excessive deformation of the enclosure.

[0028] As Figure 9 shown, the second auxiliary component 143 includes a vertical plate 1431, a sliding plate 1432, and a second auxiliary plate 1433. The vertical plate 1431 is slidably connected to the top of the sliding frame 142. The sliding plate 1432 is fixed to the bottom of the vertical plate 1431. The second auxiliary plate 1433 is fixed to the surface of the sliding plate 1432. The surface of the second auxiliary plate 1433 is in contact with the surface of the second limiting plate 141. The surface of the sliding plate 1432 is in fit with the surface of the elastic piece 144.

[0029] Adopting the above solution: when the water storage tank 8 descends under force, the second limiting plate 141 descends and presses the second auxiliary plate 1433. The vertical plate 1431 moves under force. At this time, the elastic piece 144 is compressed and deformed. After that, under the elastic potential energy of the elastic piece 144, the sliding plate 1432 drives the vertical plate 1431 to return to its original position. At this time, the second auxiliary plate 1433 and the second limiting plate 141 cooperate to limit the position of the water storage tank 8. Accordingly, when the cross plate 9 and the inner plate 12 ascend, the possibility of the water storage tank 8 ascending can be reduced, thereby restricting the relative position between the lower pressing plate 7 and the extrusion mechanism 4.

[0030] As Figure 3 shown, the moving mechanism 19 includes a thin rod 191, a piston plate 192, and a push rod 193. The thin rod 191 is fixed to the inner wall of the air injection box 17. The piston plate 192 is slidably sleeved on the surface of the thin rod 191. The surface of the piston plate 192 is in fit with the inner wall of the air injection box 17. One end of the push rod 193 is fixed to the surface of the piston plate 192. The other end of the push rod 193 slidably penetrates through the fixed frame 16 and is fixed with a moving plate 194. The arc plate 20 is fixed to the surface of the moving plate 194.

[0031] Adopting the above solution: the air pipe 18 conveys the air inside the airbag 5 to the inside of the air injection box 17. The piston plate 192 is driven to move by air pressure. The push rod 193 drives the moving plate 194 to move accordingly. The arc plate 20 moves accordingly to drive the inclined plate 21 to move, so that the inclined plate 21 can cooperate with the lifting mechanism 22.

[0032] AsFigure 5 As shown in the figure, the lifting mechanism 22 includes a vertical frame 221, a lifting frame 222 and a tension spring 223. The vertical frame 221 is fixed to the top of the base 1. The lifting frame 222 slides through the top of the vertical frame 221. The top of the inclined plate 21 is slidably connected to the bottom of the lifting frame 222. The top of the lifting frame 222 is in contact with the bottom of the force-bearing plate 24. The two ends of the tension spring 223 are respectively fixed to the bottom of the inner wall of the vertical frame 221 and the bottom of the lifting frame 222.

[0033] With the above solution: when the inclined plate 21 moves horizontally with the arc plate 20, the inclined plate 21 can lift the lifting frame 222. At this time, the force-bearing plate 24 drives the cross plate 9 to lift through the side plate 23. Then, under the elastic force of the tension spring 223, the lifting frame 222 can reset, so that the cross plate 9 and the inclined plate 21 can reset.

[0034] As Figure 5 - Figure 6 As shown in the figure, the sealing mechanism 25 includes a rectangular plate 251. The surface of the rectangular plate 251 is fixed to the surface of the arc plate 20. An extension rod 252 is fixed to the surface of the rectangular plate 251. The extension rod 252 slides through the water outlet pipe 27. One end of the extension rod 252 is fixed with a sealing plate 253. The surface of the sealing plate 253 is in contact with the inner wall of the water outlet pipe 27.

[0035] A baffle 30 and a clamping block 31 are fixed to the inner wall of the water outlet pipe 27. The bottom of the baffle 30 is in contact with the top of the sealing plate 253. When the sealing mechanism 25 is idle, the baffle 30 and the sealing plate 253 cooperate to block one side of the water outlet pipe 27 to prevent water from flowing out through the water delivery pipe 28. The setting of the clamping block 31 can limit the moving position of the sealing plate 253.

[0036] With the above solution: when the arc plate 20 moves, the rectangular plate 251 drives the extension rod 252 to move accordingly. The sealing plate 253 moves with the extension rod 252 to seal the drain pipe 29, reducing the possibility of water being discharged from the drain pipe 29. At this time, the water can be discharged into the interior of the water storage tank 8 through the water delivery pipe 28.

[0037] Working principle and usage process of the present invention: The staff installs this risk assistance system in the foundation pit and makes the top of the cross plate 9 fit with the bottom of the existing building pile foundation enclosure. After that, the staff can start the water pump 26 during the construction process as needed. The water pump 26 cooperates with the water inlet pipe to pump out the water source at the construction site. The pumped water source is discharged through the water outlet pipe 27 and the drain pipe 29, thereby reducing the impact of water accumulation on the construction operation. When the drainage volume affects the building, the force on the enclosure deforms and decreases. At this time, the cross plate 9 is stressed and conducts the force to the water storage tank 8. The lower pressing plate 7 then descends and presses the extrusion plate 42. The air bag 5 is squeezed by the movement of the extrusion plate 42 and discharges the air through the air pipe 18 into the inside of the air injection box 17. At this time, the piston plate 192 drives the moving plate 194 to move through the push rod 193. The arc plate 20 moves with the moving plate 194. When the arc plate 20 moves, the rectangular plate 251 and the inclined plate 21 move simultaneously. The rectangular plate 251 and the extension rod 252 drive the sealing plate 253 to move, and the sealing plate 253 blocks the drain pipe 29. The water source inside the drain pipe 29 stops flowing. The staff can timely judge the risk of building settlement according to the stop of the drainage operation of the drain pipe 29. At the same time, the water source inside the water outlet pipe 27 is discharged into the inside of the water storage tank 8 through the water delivery pipe 28 and lifts the inner plate 12, thereby lifting the cross plate 9. And when the water delivery pipe 28 injects water into the water storage tank 8, the movement of the inclined plate 21 can drive the lifting frame 222 to lift. The force receiving plate 24 and the side plate 23 cooperate to lift the cross plate 9. The cross plate 9 is lifted by the assistance of water injection and the lifting of the side plate 23 to support the enclosure and reduce the possibility of further deformation of the enclosure, thereby improving the safety during the development of the deep underground space; When the water storage tank 8 descends, the second limit plate 141 descends accordingly. The second limit plate 141 and the second auxiliary plate 1433 cooperate to limit the height of the water storage tank 8 after the descent, thereby ensuring the stability of the relative position between the lower pressing plate 7 and the extrusion plate 42. Accordingly, the stability of the position of the moving mechanism 19 can be increased. After the cross plate 9 is lifted by the force, the first limit plate 132 and the first auxiliary plate 1332 cooperate to limit the height of the cross plate 9, preventing the possibility of the cross plate 9 descending, so as to ensure the effect of the cross plate 9 supporting the enclosure. The first limit plate 132 and the first auxiliary plate 1332 cooperate. When the cross plate 9 is stressed again, continue to apply force to the first auxiliary plate 1332 through the first limit plate 132. At this time, the water storage tank 8 can be stressed and descend again, so as to continue to squeeze the remaining air in the air bag 5 through the cooperation of the lower pressing plate 7 and the extrusion plate 42.
