Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an underground anti-floating structure of a building under a thin soil layer. Background Art
[0002] When the soil cover of an underground building is not heavy enough, the building may float up under the action of surface water and groundwater. When the underground building floats up, the structural floor and columns will crack, causing damage to the structure of the entire underground building. To avoid this phenomenon, anti-floating structures are usually set up to drain water, thereby preventing the building from floating up.
[0003] 202320945800.5 An anti-floating drainage system for an underground building, comprising: a basement consisting of a bottom plate and side walls arranged around the outside of the bottom plate, backfill soil being arranged outside the bottom plate and the side walls; the anti-floating drainage system comprises: an anchor rod, one end of which is connected to the bottom surface of the bottom plate, and the other end of which is fixed in the backfill soil; a first drainage pipe network, comprising a first water inlet and a first water outlet, the first water inlet passing through the bottom plate and connected to the basement, and the water outlet being connected to a rainwater pipe of a city pipe network system; a second drainage pipe network, comprising a second water inlet and a second water outlet, the second water inlet passing through an elevated drainage level arranged on the side wall to connect to the basement, and the second water outlet being connected to a sewage pipe of the city pipe network system; wherein the position of the elevated drainage level is higher than the position of the bottom plate, and when the water level in the underground chamber reaches the position of the elevated drainage level, the sewage in the basement is discharged into the sewage pipe through the second drainage pipe network.
[0004] However, this technical solution mainly discharges water into the urban pipeline network by gravity drainage. When water is discharged from the pipe by gravity, outside air can easily enter the pipe, leaving air inside the pipe. The air rises in the pipe or is discharged with the water flow, occupying part of the space in the pipe, thereby reducing the drainage flow rate and affecting the working efficiency of the anti-floating system. If a water pump is used to pump water, firstly, a liquid level sensor is required to monitor whether there is water, and secondly, electricity is required to drive the water pump, resulting in a high operating cost of the anti-floating structure. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide an underground anti-floating structure for buildings under a thin soil layer to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an underground anti-floating structure of a building under a thin soil layer, comprising a wall, a shell connected to the bottom of the wall, and a siphon and a straight pipe connected to the top of the shell on both sides, a first water delivery trough and a second water delivery trough are respectively arranged on both sides of the inside of the shell, and blocking frames are connected to the inside of the first water delivery trough and the second water delivery trough, and a spring is connected between the blocking frame and the shell.
[0007] By adopting the above technical scheme, when the amount of water is small, the water is sent to the combined pipe for discharge through the straight discharge pipe and the second water supply trough. When the amount of water is large, and the internal flow of the straight discharge pipe and the first water supply trough is reduced due to the influence of air, making it difficult for the discharge volume to keep up with the water intake, the liquid level in the wall rises and covers the siphon tube. Then the siphon tube uses the siphon effect to make the water in the wall pass through the siphon tube and the first water supply trough into the combined pipe for discharge under the influence of the dual forces of atmospheric pressure and gravity. At the same time, the water flow in the first water supply trough pushes the blocking frame to move left to close the first water supply trough, thereby preventing the straight discharge pipe from affecting the siphon drainage operation. When the siphon pipe cannot absorb water, the water flow in the first water supply trough is reduced. At this time, the spring drives the blocking frame to move right to open the first water supply trough, thereby discharging the remaining water through the straight discharge pipe and the first water supply trough.
[0008] Furthermore, the siphon tube is connected to the first water supply trough, and the straight discharge pipe is connected to the second water supply trough.
[0009] By adopting the above technical solution, when the amount of water is small, the water is sent into the combined pipe through the straight discharge pipe and the second water supply trough for discharge. When the amount of water is large, the liquid level in the wall rises above the siphon tube. Then the siphon tube uses the siphon effect to make the water in the wall pass through the siphon tube and the first water supply trough into the combined pipe under the influence of the dual forces of atmospheric pressure and gravity and be quickly discharged.
[0010] Furthermore, the right side of the blocking frame is slidably connected to the first water supply trough, and the right side cross-section of the outer surface of the blocking frame is in a "T" shape.
[0011] By adopting the above technical solution, the water flow in the first water supply trough pushes the blocking frame to move left to close the first water supply trough, thereby preventing the straight discharge pipe from affecting the siphon drainage operation, thereby accelerating the drainage efficiency.
[0012] Furthermore, the left side of the blocking frame is slidably connected to the second water supply trough.
[0013] By adopting the above technical solution, when the siphon tube cannot absorb water, the water flow in the first water supply trough is reduced. At this time, the spring drives the blocking frame to move right to open the first water supply trough, so that the remaining water is discharged through the straight discharge pipe and the first water supply trough.
[0014] Furthermore, a guide plate is connected to the lower part of the wall, and a confluence pipe is connected to the bottom of the shell.
[0015] By adopting the above technical solution, when the amount of water is small, the water is guided to the direction of the straight pipe through the guide plate, and then sent to the combined pipe through the straight pipe and the second water supply trough for discharge.
[0016] Furthermore, the inner circle of the guide plate is inclined downward, and the confluence pipe is connected to the first water supply trough and the second water supply trough.
[0017] By adopting the above technical scheme, water is guided to the direction of the straight discharge pipe through the guide plate, and the water is sent to the combined pipe through the straight discharge pipe and the second water supply trough for discharge, or the siphon pipe utilizes the siphon effect, so that the water in the wall is affected by the dual forces of atmospheric pressure and gravity and passes through the siphon pipe and the first water supply trough into the combined pipe for rapid discharge.
[0018] Furthermore, a bracket is connected inside the wall, and a filter is connected to the outer surface of the bracket.
[0019] By adopting the above technical solution, impurities in the water are blocked by the filter to prevent the impurities from entering the pipeline and causing blockage affecting drainage. At the same time, the large-sized filter increases the efficiency of water flow and reduces the impact of the filter on the flow rate of the water when filtering water.
[0020] Furthermore, the outer ring of the filter is inclined downward.
[0021] By adopting the above technical solution, the outer circle of the filter is tilted downward, so that the impurities on the filter are displaced toward the wall due to the impact of water flow and gravity, thereby reducing the occurrence of filter clogging.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] The utility model uses a siphon, a straight-discharge pipe, a first water delivery trough, a second water delivery trough, a blocking frame and a spring. When the amount of water is small, the water is delivered to the combined pipe through the straight-discharge pipe and the second water delivery trough for discharge. When the amount of water is large, and the internal flow of the straight-discharge pipe and the first water delivery trough is reduced due to the influence of air, so that the discharge volume is difficult to keep up with the water intake volume, the liquid level in the wall rises and covers the siphon. Then the siphon uses the siphon effect to make the water in the wall pass through the siphon and the first water delivery trough under the influence of the dual forces of atmospheric pressure and gravity, enter the combined pipe for discharge, and at the same time, the water flow in the first water delivery trough pushes the blocking frame to move left to close the first water delivery trough, thereby preventing the straight-discharge pipe from affecting the siphon drainage operation. When the siphon cannot absorb water, the water flow in the first water delivery trough is reduced. At this time, the blocking frame is driven by the spring to move right to open the first water delivery trough, thereby discharging the remaining water through the straight-discharge pipe and the first water delivery trough. The siphon effect is used to quickly discharge water, which speeds up the drainage efficiency and improves the anti-floating effect. At the same time, no additional electrical drive is required to reduce energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0030] The following describes an embodiment of the utility model based on its overall structure.
[0031] Embodiment 1:
[0032] An underground anti-floating structure for buildings under a thin soil layer, such as Figure 1-Figure 4 As shown, it includes a wall 1, a shell 8 is connected to the bottom of the wall 1, and a siphon pipe 5 and a straight pipe 6 are connected to the top of the shell 8 on both sides. When the water volume is small, the water is sent to the combined pipe 7 through the straight pipe 6 and the second water feeding trough 10 for discharge; the first water feeding trough 9 and the second water feeding trough 10 are respectively arranged on both sides of the shell 8. The siphon pipe 5 is connected to the first water feeding trough 9, and the straight pipe 6 is connected to the second water feeding trough 10. The siphon pipe 5 uses the siphon effect to make the water in the wall 1 pass through the siphon under the influence of the dual forces of atmospheric pressure and gravity. The pipe 5 and the first water delivery trough 9 enter the combined pipe 7 and are quickly discharged; the first water delivery trough 9 and the second water delivery trough 10 are internally connected with a blocking frame 11, and the right side cross-section of the outer surface of the blocking frame 11 is in a "T" shape. A spring 12 is connected between the blocking frame 11 and the shell 8. The right side of the blocking frame 11 is slidably connected to the first water delivery trough 9, and the left side of the blocking frame 11 is slidably connected to the second water delivery trough 10. The water flow in the first water delivery trough 9 pushes the blocking frame 11 to move left to close the first water delivery trough 9, thereby preventing the straight discharge pipe 6 from affecting the siphon drainage operation, thereby accelerating the drainage efficiency.
[0033] See also Figure 1-Figure 3In the above embodiment, a guide plate 4 is connected to the lower part of the wall 1, and the inner circle of the guide plate 4 is inclined downward. The water is guided to the direction of the straight discharge pipe 6 through the guide plate 4. A confluence pipe 7 is connected to the bottom of the shell 8. The confluence pipe 7 is connected to the first water supply trough 9 and the second water supply trough 10, and the water is discharged into the urban pipe network through the confluence pipe 7.
[0034] Embodiment 2:
[0035] On the basis of the above-mentioned embodiment one, although by setting up the siphon tube 5, the straight discharge pipe 6, the first water supply trough 9, the second water supply trough 10, the blocking frame 11 and the spring 12, the siphon effect can be used to quickly discharge water, thereby accelerating the drainage efficiency and improving the anti-floating effect, and no additional electrical drive is required to reduce energy consumption; but there is a lot of mud, garbage and gravel in the water, which may block the pipeline; now by setting up the filter 3, impurities can be prevented from entering the pipeline to cause blockage and affect drainage.
[0036] See also Figure 1-Figure 3 In the above embodiment, a bracket 2 is connected inside the wall 1, and a filter 3 is connected to the outer surface of the bracket 2. The filter 3 blocks impurities in the water to prevent the impurities from entering the pipeline and causing blockage and affecting drainage; the outer circle of the filter 3 is tilted downward, so that the impurities on the filter 3 are displaced toward the wall 1 due to the impact of water flow and gravity, thereby reducing the occurrence of blockage of the filter 3.
[0037] The implementation principle of the utility model is as follows: first, when the amount of water is small, the water is guided to the direction of the straight pipe 6 through the guide plate 4, and then the water is sent to the combined pipe 7 through the straight pipe 6 and the second water delivery trough 10 for discharge, and at the same time, the impurities in the water are blocked by the filter 3 to prevent the impurities from entering the pipeline and causing blockage and affecting the drainage. At the same time, the outer circle of the filter 3 is tilted downward, so that the impurities on the filter 3 are displaced toward the wall 1 under the impact of the water flow and the influence of gravity, reducing the occurrence of blockage of the filter 3. At the same time, the large-sized filter 3 increases the efficiency of the water flow, reducing the significant impact of the filter 3 on the flow rate of the water when filtering water;
[0038] When the amount of water is large, the liquid level in the wall 1 rises above the siphon tube 5. Then the siphon tube 5 uses the siphon effect to make the water in the wall 1 pass through the siphon tube 5 and the first water delivery trough 9 under the influence of the dual forces of atmospheric pressure and gravity and enter the combined pipe 7 for rapid discharge. At the same time, the water flow in the first water delivery trough 9 pushes the blocking frame 11 to move left to close the first water delivery trough 9, thereby preventing the straight discharge pipe 6 from affecting the siphon drainage operation, thereby accelerating the drainage efficiency.
[0039] When the siphon 5 cannot absorb water, the water flow in the first water supply trough 9 decreases. At this time, the spring 12 drives the blocking frame 11 to move right to open the first water supply trough 9, so that the remaining water is discharged through the straight discharge pipe 6 and the first water supply trough 9.
[0040] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
