Description

Technical Field

[0001] This application relates to the technical field of foundation drainage, and in particular to a foundation settlement prevention and drainage system for high-rise buildings. Background Technology

[0002] During the construction of multi-story buildings, foundations must be excavated to ensure the stability of the building. This is especially true for high-rise buildings, where foundations need to be quite deep. At this depth, groundwater can easily seep out, and surface water and rainwater can also easily collect in the foundation. If drainage and protection measures are not properly implemented, the foundation may collapse, and the high-rise building may subsequently experience settlement.

[0003] Open drainage is a common method for foundation drainage. It involves excavating drainage ditches around or in the center of the foundation pit and setting up sump pits at the four corners. Water from the pit flows through the drainage ditches into the sump pits and is then pumped out. However, simple sump pits and water levels cannot be monitored effectively. Workers need to check the water level periodically for timely removal, which is inconvenient and increases their workload. Furthermore, untimely manual monitoring can lead to water overflow, thus affecting construction progress.

[0004] Existing drainage systems that monitor water levels to automatically activate water pumps typically use level sensors to monitor two water levels. When the water level is high, the controller starts the pump, and when the water level is low, the pump shuts off. However, these contact-type sensors are not only expensive but also susceptible to interference from air, pressure, sealing issues, and electromagnetic interference, which can affect their performance and even cause damage, reducing the lifespan of the monitoring equipment and potentially impacting construction progress. Summary of the Invention

[0005] In order to improve the shortcomings of sensor-based control systems that are prone to failure, this application provides a high-rise building foundation anti-settlement drainage system.

[0006] This application provides a drainage system for preventing settlement of foundations in high-rise buildings, employing the following technical solution:

[0007] A high-rise building foundation settlement prevention and drainage system includes a water pump, drainage ditches arranged around the perimeter of the foundation, and a collection well located at the corner of the foundation. The water pump is connected to a pumping pipe extending into the bottom of the collection well. A waterproof tank and a drive mechanism are installed inside the collection well. A switch electrically connected to the water pump is installed inside the waterproof tank. The drive mechanism includes an adjustment control and a buoyancy component. The buoyancy component is vertically movably connected to the waterproof tank, and its lower end extends through the bottom of the waterproof tank. One end of the adjustment control is hinged to the waterproof tank, and the other end is movably connected to the buoyancy component, rotating as the buoyancy component moves vertically. An elastic element is connected to the adjustment control and abuts against the buoyancy component. When the adjustment control rotates toward the bottom of the waterproof tank, the elastic element provides downward pressure on the buoyancy component. When the adjustment control rotates toward the top of the waterproof tank, the elastic element provides upward support to the buoyancy component. A touch control is provided on the buoyancy component. When the buoyancy component floats upward and drives the adjustment control to rotate toward the top of the waterproof tank, the touch control abuts against the switch and activates the switch. When the buoyancy component descends and drives the adjustment control to rotate toward the bottom of the waterproof tank, the touch control disengages from the switch and deactivates the switch.

[0008] By adopting the above technical solution, when the water volume in the collection tank is low, the buoyancy component is located at the bottom of the collection well, and the adjustment control rotates downward under the action of gravity. At this time, the elastic force of the elastic component on the buoyancy component tilts downward, thereby limiting the buoyancy component from floating upward. As the water volume increases, the volume of the buoyancy component submerged in water increases, thereby gradually increasing the buoyancy until the buoyancy exceeds the sum of the weight, friction, and vertical component of the elastic force of the drive mechanism. The buoyancy component becomes unbalanced and begins to float upward, eventually reaching the highest position. The adjustment control is driven by the buoyancy component to rotate upward, at which point the elastic force of the elastic component on the buoyancy component changes to tilting upward. When the buoyant component rises to the position where the touch panel reaches the switch, it presses against the switch, thus starting the water pump to draw water through the suction pipe. At this point, due to the large elastic force and buoyancy, the buoyant component is still at its highest position. As the water level drops, the buoyancy gradually decreases, and the buoyant component begins to move downwards. The friction force also reverses, and the water volume is now low. Until the sum of the vertical components of buoyancy, friction, and elastic force is less than gravity, the buoyant component begins to descend, the touch panel gradually disengages from the switch, shutting off the water pump. The control panel also rotates downwards, and the elastic force of the elastic component on the buoyant component changes to a downward tilt. This system automatically starts and stops the water pump without manual monitoring and is controlled by elastic force, water buoyancy, and the weight of the mechanism itself. The structure is stable and not easily damaged. The switch itself is located in a high position in the sump, preventing it from being submerged, and a waterproof box further extends its service life.

[0009] Optionally, the buoyancy component includes a connecting rod that passes through and connects to the waterproof box and a float that connects to the lower end of the connecting rod, and the touch control part is disposed on the side of the connecting rod near the switch.

[0010] By adopting the above technical solution, the buoyancy component is specifically divided into a float at the lower end and a connecting rod with greater rigidity. The touch control part is located on the side of the connecting rod facing the switch. When the connecting rod floats up to the height of the switch, the touch control part can continuously press the switch to turn on the water pump.

[0011] Optionally, the adjustment control is disposed inside the waterproof box, and a linkage groove along the length direction is provided on the adjustment control. A linkage part is fixedly provided at the top of the connecting rod, and the linkage part slides in the linkage groove. One end of the elastic element is connected to the adjustment control and the other end is pressed against the linkage part.

[0012] By adopting the above technical solution, the linkage part of the connecting rod slides in the linkage groove of the adjustment control, thereby realizing the rotation of the adjustment control driven by the connecting rod, and thus realizing the change of the direction of the elastic force applied by the elastic element to the buoyancy element; the adjustment control is set in a waterproof box to avoid being submerged in water, reducing the resistance encountered during rotation, and making it easier to control the buoyancy element and thus control the opening and closing switch.

[0013] Optionally, a first buffer is provided at the end of the linkage groove that is away from the adjustment control and hinged to the waterproof box, and the linkage part abuts against the first buffer when the connecting rod is in the highest position.

[0014] By adopting the above technical solution, when the buoyancy of the buoyancy component increases to the maximum critical point, it will float upward rapidly. At the highest point, due to the high speed, the linkage part will hit the bottom of the linkage groove. The first buffer component plays a buffering and absorbing role, which can reduce the possibility of the buoyancy component vibrating up and down, reduce the wear of the linkage part, and further improve the stability of the structure.

[0015] Optionally, the top of the waterproof tank is provided with a second buffer that abuts against the end of the connecting rod away from the float when the connecting rod is in its highest position.

[0016] By adopting the above technical solution, the length of the connecting rod is set so that the buoyancy component can abut against the second buffer component at the top of the waterproof box when it is at its highest point, which further plays a role in buffering and absorbing the impact force, and provides a buffering effect on the connecting rod, making the structure more stable.

[0017] Optionally, the water collection well includes a connected filtration zone and a pumping zone, the pumping zone is fitted with a water storage tank, the water storage tank is provided with a filtration section on the side facing the filtration zone, and the waterproof tank and the drive mechanism are disposed inside the water storage tank.

[0018] By adopting the above technical solution, the water entering the collection well is first filtered through the filter section before entering the water storage tank and being pumped by the water pump, which reduces the possibility of water pump blockage and damage and extends its service life.

[0019] Optionally, a removable filter basket is provided in the filtration zone.

[0020] By adopting the above technical solution, the secondary filtration of water through the filter basket and filtration section reduces the possibility of impurities in the water entering the water storage tank, and the impurities are intercepted in the filter basket, making it easy to clean.

[0021] Optionally, a rotating plate is hinged to the bottom of the water tank, the hinged end of the rotating plate is away from the waterproof tank, and a traction rope is connected between the rotating plate and the buoyancy component.

[0022] By adopting the above technical solution, some impurities or sand will still accumulate at the bottom of the water tank after long-term use. When the buoyancy component floats upward, the traction rope pulls up one end of the rotating plate, which can make the impurities slide towards the hinge end, making it easy to clean. When the water volume is low, the rotating plate can also gather the water so that the water pipe can suck it up.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. The water pump is automatically turned on and off by adjusting the direction of the elastic force and the magnitude of the buoyancy, eliminating the need for manual monitoring, reducing workload, and improving construction efficiency;

[0025] 2. The mechanical structure controls the start and stop of the water pump, which is more stable and less prone to damage compared to sensor control;

[0026] 3. By changing the direction of the elastic element, the buoyancy element can be kept at the highest point for a longer time and fall more slowly, thereby allowing more water to be drawn in. In addition, the rotating plate can also gather water to facilitate the suction of the water pipe.

[0027] 4. The switch itself is located at a high position in the water collection well, so it will not be submerged in water. It also has a waterproof box that is sealed to prevent water damage, further extending its service life.

[0028] 5. The rotating plate allows impurities to accumulate on one side and away from the bottom of the waterproof tank, making cleaning easier;

[0029] 6. The rotating plate can push away impurities below the float, reducing the possibility of impurities accumulating above the float after long-term use and improving the stability of the structure. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0036] Reference Figure 1 This application discloses a high-rise building foundation anti-settlement drainage system, including a water pump 3, a drainage ditch 1 set around the foundation, and a water collection well 2 located at the corner of the foundation. The water pump 3 is connected to a pumping pipe 4 extending into the bottom of the water collection well 2. The water collection well 2 is provided with a switch 7 electrically connected to the water pump 3 and a drive mechanism 8 for controlling the opening and closing of the switch 7.

[0037] Reference Figure 2 The water collection well 2 may include a connected filtration zone 21 and a pumping zone 22. Water in the drainage ditch 1 flows to the pumping zone 22 after being filtered by the filtration zone 21. A water storage tank 5 is embedded in the pumping zone 22. A filter section 62 is provided on the side of the water storage tank 5 facing the filtration zone 21 near the bottom of the filtration zone 21. The filter section 62 has several filter holes. The drive mechanism 8 and the pumping pipe 4 are both located in the pumping zone 22. A filter screen may also be provided at the inlet of the pumping pipe 4.

[0038] Reference Figure 2 To facilitate the cleaning of impurities, a detachable filter basket 13 is provided in the filtration zone 21. The height of the side of the filter basket 13 closest to the drain well does not exceed the bottom of the drain well, and a handle is provided on the filter basket 13 for easy lifting.

[0039] Reference Figure 2 and Figure 3A waterproof tank 6 is fixed to the inner wall of the water storage tank 5 near the top. A switch 7 is fixed to the inner wall of the waterproof tank 6. The switch 7 is set to start the water pump 3 when pressed and turn off the water pump 3 when released. The drive mechanism 8 includes an adjustment control 9 and a buoyancy component 10. The buoyancy component 10 includes a connecting rod 101 and a float 102 fixed to the lower end of the connecting rod 101. The volume of the float 102 can be set to be larger in order to obtain greater buoyancy. The waterproof box 6 is sealed, with only a through hole 61 at the bottom for the connecting rod 101 to pass through and move vertically. The inner wall of the through hole 61 is fitted with a waterproof sealing element 14, which can be a rubber strip. A touch part 103 is provided on the side of the connecting rod 101 near the switch 7. The top of the connecting rod 101 near the switch 7 is chamfered so that the touch part 103 gradually presses against the switch 7 to open when the connecting rod 101 moves upward. The touch part 103 is arranged along the length of the connecting rod 101 so that when the connecting rod 101 moves upward to the height of the switch 7, the touch part 103 can continuously press the switch 7. In addition, the connecting rod 101 can be set as a rectangle or have other limiting parts to restrict its rotation. The through hole 61 is set to a shape consistent with the cross-section of the connecting rod 101. When the float 102 is at the lowest point and abuts against the bottom wall of the water storage tank 5, the connecting rod 101 does not detach from the water tank 6.

[0040] Reference Figure 3 The inner wall of the waterproof box 6 is hinged to an adjustment control 9 via a pivot. The other end of the adjustment control 9 is movably connected to the buoyancy component 10, and the adjustment control 9 can rotate as the buoyancy component 10 moves vertically. Specifically, the adjustment control 9 has a linkage groove 91 along its length, and a linkage part 104 is fixedly provided at the top of the connecting rod 101. The linkage part 104 can be configured as a round shaft, and the linkage part 104 slides within the linkage groove 91, thereby enabling the up-and-down movement of the connecting rod 101 to drive the rotation of the adjustment control 9.

[0041] Reference Figure 3 An elastic element 11 is connected to the adjustment control 9 and abuts against the linkage part 104. The elastic element 11 can be disposed in the linkage groove 91. In this embodiment, the elastic element 11 is preferably a compression spring. When the adjustment control 9 rotates toward the bottom of the waterproof box 6, the elastic element 11 provides downward pressure to the buoyancy member 10. When the adjustment control 9 rotates toward the top of the waterproof box 6, the elastic element 11 provides upward support to the buoyancy member 10.

[0042] Reference Figure 3 and Figure 4As the water volume increases, when the buoyancy of the buoyancy component 10 increases to its maximum critical point, it will float upwards rapidly. At the highest point, due to the high speed, the linkage part 104 will impact the bottom of the linkage groove 91. To absorb the impact force, a first buffer 92 is provided at the end of the linkage groove 91 away from the adjustment control 9 and hinged to the waterproof box 6. When the connecting rod 101 is in its highest position, the linkage part 104 abuts against the first buffer 92. Optionally, but not limited to, the top of the waterproof box 6 is also provided with a second buffer 12 that abuts against the end of the connecting rod 101 away from the float 102 when the connecting rod 101 is in its highest position. Both the first buffer 92 and the second buffer 12 are made of flexible materials with a certain deformation capacity, such as sponge or rubber.

[0043] Furthermore, after prolonged use, some impurities or sand may accumulate at the bottom of the water tank 5. To facilitate cleaning, a rotating plate 15 is hinged to the bottom of the water tank 5. The rotating plate 15 is made of lightweight or hollow material. The shape of the rotating plate 15 is consistent with the bottom of the water tank 5. The hinge end of the rotating plate 15 is located on the side away from the waterproof tank 6. A traction rope 16 is connected between the rotating plate 15 and the buoyancy component 10. One end of the traction rope 16 is fixed to the bottom of the float 102, and the other end is fixed to the end of the rotating plate 15 away from the hinge.

[0044] The implementation principle of a high-rise building foundation anti-settlement drainage system according to an embodiment of this application is as follows:

[0045] When the water level in the collection tank is low, the float 102 is located at the bottom of the storage tank 5. The control 9 rotates downward under the action of gravity. At this time, the elastic force of the elastic element 11 on the buoyancy element 10 tilts downward, thus limiting the upward movement of the buoyancy element 10. As the water level increases, the volume of the float 102 submerged in water increases, thus gradually increasing the buoyancy. Until the buoyancy exceeds the sum of the weight, friction, and vertical component of the elastic force of the drive mechanism 8, the buoyancy element 10 becomes unbalanced and begins to float upward, reaching its highest position. The control 9 rotates upward under the influence of the buoyancy element 10. At this time, the elastic force of the elastic element 11 on the buoyancy element 10 changes to tilting upward. When the buoyancy component 10 rises to the position where the touch unit 103 reaches the switch 7, it begins to press against the switch 7, thereby starting the water pump 3 to pump water through the water pipe 4. At this time, due to the large elastic force and buoyancy, the buoyancy component 10 is still at its highest position. As the water level drops, the buoyancy gradually decreases, and the buoyancy component 10 begins to have a downward movement tendency. The friction force changes to the opposite direction, and at this time, the water volume is already small. Until the sum of the vertical components of buoyancy, friction, and elastic force is less than the gravity, the buoyancy component 10 begins to descend, the touch unit 103 gradually disengages from the switch 7, causing the water pump 3 to shut off. The adjustment control 9 also rotates downward, and the elastic force of the elastic component 11 on the buoyancy component 10 changes to tilting downward. This achieves automatic starting and stopping of the water pump 3 without manual monitoring, and the structure is stable and not easily damaged.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
