Description

Technical Field

[0001] The invention belongs to the technical field of basement anti-floating, and in particular relates to a device for preventing basement bottom slab from floating and leaking. Background Art

[0002] In recent years, engineering accidents caused by anti-floating problems have attracted widespread attention. This is mainly due to the buoyancy force exerted by groundwater on underground structures. When this buoyancy force exceeds the deadweight of the structure, the structure may arch or float up and become unstable and fail. As the foundation of a building, the quality of its design and construction directly affects the stability and safety of the building. Among them, the anti-floating of the basement is particularly important because it is directly related to the safety of the building under changes in the groundwater level or other hydrogeological conditions. After the construction of the basement is completed, precipitation often stops. Before the main structure is fully constructed, the deadweight of the basement may not be able to resist the buoyancy of the groundwater. Or, during a season with concentrated rainfall, the rising water level will cause the bottom plate to float. Therefore, it is extremely important to take appropriate anti-floating measures after the basement structure is completed. To this end, a device is proposed to prevent the floating and leakage of the basement bottom plate. Summary of the Invention

[0005] Preferably, the claw assembly includes a plurality of mounting grooves circumferentially opened on the outer circumference of the anchor pile, and a limiting claw is rotatably connected in the mounting groove, and the limiting claw is connected to the mounting groove via a spring sheet.

[0006] Preferably, water inlet holes are opened around the lower end of the water storage pool, and a filter is provided on the water inlet holes. A connecting pipe is provided on the water storage pool, and the connecting pipe is connected between the floating plate and the bottom of the water storage pool.

[0007] Preferably, the water storage tank is communicated with the bottom cylinder, and a slide is slidably connected in the bottom cylinder, and the slide is used to adjust the water storage amount of the water storage tank.

[0008] Preferably, a connecting column is fixedly connected to the bottom of the floating plate, and the connecting column passes through the water storage pool and the skateboard in sequence. The bottom of the skateboard is fixedly connected to a vertical plate, and the vertical plate is fixedly connected to rack 2. Rack 1 is fixedly connected to the outer periphery of the connecting column, and a gear is rotatably connected in the bottom cylinder, and the gear is located between rack 1 and rack 2.

[0009] Preferably, the anti-floating plate three is fixedly connected to the vertical plate, a movable groove is opened on the outer periphery of the bottom tube, and the anti-floating plate three slides in the movable groove; a protective cover is fixedly connected to the outer periphery of the bottom tube, and the anti-floating plate three is located in the protective cover.

[0010] Preferably, a sleeve rod is slidably connected to the anti-floating tube, and the two ends of the sleeve rod are respectively fixedly connected to a connecting rod and an insertion rod, the connecting rod is fixedly connected to the sleeve ring, and a spring is sleeved on the connecting rod, one end of the spring is fixedly connected to the front end of the anti-floating tube, and the other end is fixedly connected to the sleeve rod; a slot hole is opened at the lower end of the vertical plate, and the insertion rod corresponds to the slot hole.

[0011] Preferably, a liquid level sensor is provided in the water storage tank, a bracket is fixedly connected to the top wall of the water storage tank, a pressure sensor is installed on the bracket, the pressure sensor corresponds to the float plate, and the liquid level sensor and pressure sensor are used to monitor the liquid level in the water storage tank and the position of the float plate.

[0012] Preferably, four anti-floating plates 1, 2, 3 and 4 anti-floating tubes are provided on the circumference.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0014] 1. The device for preventing the basement floor from floating and leaking provides basic support for anti-floating through the cooperation of anchor piles and claw assemblies. When the anchor pile passes through anti-floating plate 1, anti-floating plate 2, anti-floating plate 3 and anti-floating tube, the limit claw of the claw assembly is deployed under the action of the spring sheet, so that the anchor pile can resist the anti-floating plates and rings when moving upward. This mechanical limit structure directly hinders the upward movement of the basement due to buoyancy. The four anti-floating plates and anti-floating tubes distributed on the circumference increase the contact area with the foundation by being placed horizontally, further strengthening this anti-floating foundation.

[0015] 2. A device to prevent basement floor slab buoyancy and leakage. The linkage between the floating plate and the water reservoir dynamically adjusts the anti-buoyancy capacity. When groundwater enters the reservoir through the water inlet, the floating plate moves upward due to buoyancy, driving the connecting column and rack 1 to drive the gear, which in turn drives rack 2 to push down on the anchor pile. Simultaneously, the slide slides within the base tube to adjust the volume of the water reservoir. This automatically stores more groundwater based on the water level, and through the rack and pinion transmission, it converts buoyancy into downward pressure against the anchor pile, increasing the anti-buoyancy capacity as the water level rises, creating a self-adaptive adjustment mechanism.

[0016] 3. Device to prevent basement floor slab from floating and leaking. When the floating plate moves up and drives the vertical plate downward, the sleeve rod in the anti-floating tube inserts the rod into the slot of the vertical plate under the action of the spring. At this time, the connecting rod generates lateral tension on the anchor pile, forming a three-dimensional constraint with the downward pressure of the anti-floating plate. It not only presses the anchor pile downward in the vertical direction, but also makes the anchor pile more tightly connected to the foundation, water storage tank and bottom tube through lateral tension. This multi-directional force constraint mechanism effectively avoids the loosening problem that may occur when the anchor pile is subjected to unidirectional force, and further improves the anti-floating reliability.

[0017] 4. A device to prevent basement floor slab from floating and leaking: a liquid level sensor monitors the water level in the reservoir in real time, automatically adjusting the pump power through a PLC controller to prevent overload from excessive water flow. A pressure sensor provides real-time feedback on the float plate's position to prevent excessive floating. If the water level is low but the float plate exerts pressure on the pressure sensor, this indicates overflow from the reservoir above the float plate. Water is then pumped through a connecting pipe to restore the float plate to its normal position. This intelligent monitoring and intervention mechanism not only ensures stable operation of the device but also proactively adjusts under abnormal operating conditions, ensuring the continued effectiveness of its anti-floating and anti-leakage functions.

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0039] The following is combined with Figure 1 -Attached Figure 10 , describes in detail the technical solutions provided by each embodiment of the present invention.

[0040] Example 1: Reference Figures 1-10 A device for preventing basement floor slab buoyancy and leakage includes a water reservoir 1 buried beneath the basement. A permeable layer, primarily composed of crushed stone, is provided around the reservoir 1 to facilitate pre-filtration of impurities in the water. Water inlet holes 10 are formed around the lower end of the reservoir 1, each equipped with a filter screen. A connecting pipe 3 is provided on the reservoir 1, connecting the connecting pipe 3 to a floating plate 101 and the bottom of the reservoir 1. The number and size of the water inlet holes 10 around the lower end of the reservoir 1 are determined based on the drainage volume of the basement and the amount of groundwater infiltration. The filter screen is supported by stainless steel wire, and its pore size is sufficient to filter out impurities in the water, further preventing impurities from entering the reservoir 1, clogging the pipe, or otherwise affecting the normal operation of the device. The connecting pipe 3 is made of corrosion-resistant PVC or steel pipe, preferably steel pipe in this embodiment, as it provides strength and improves its anti-buoyancy properties when buried beneath the basement. One end of the connecting pipe 3 is connected to a drainage system or other water treatment equipment to facilitate pumping out when the basement leaks into the water storage tank 1.

[0041] It also includes: a bottom tube 2, connected to the bottom of the water storage pool 1; anti-floating plate 1 11 and anti-floating plate 2 12, respectively arranged around the water storage pool 1; anti-floating plate 3 13 and anti-floating tube 14, respectively arranged around the bottom tube 2; a claw assembly 15, arranged in multiple groups on the outer periphery of the anchor pile 150, when the anchor pile 150 respectively penetrates the anti-floating plate 1 11, anti-floating plate 2 12, anti-floating plate 3 13 and anti-floating tube 14, the claw assembly 15 is deployed when it passes over the anti-floating plate 1 11, anti-floating plate 2 12, anti-floating plate 3 13 and anti-floating tube 14; the claw assembly 15 includes a plurality of mounting grooves 151 circumferentially opened on the outer periphery of the anchor pile 150, and a limiting claw 153 is rotatably connected to the mounting groove 151, and the limiting claw 153 is connected to the mounting groove 151 by a spring sheet 152. The number of mounting grooves 151 can be set according to actual needs. In this embodiment, it is preferably four evenly distributed. The spring sheet 152 is supported by a metal material with a certain elasticity, such as a stainless steel spring sheet, which can improve the corrosion resistance.

[0042] The floating plate 101 is arranged in the water storage tank 1. When the floating plate 101 is driven to move upward, the anti-floating plate 13 provides downward pressure for the anchor pile 150.

[0043] The water storage tank 1 is connected to the bottom tube 2, and a slide plate 201 is slidably connected inside the bottom tube 2. The slide plate 201 is used to adjust the water storage amount of the water storage tank 1. A seal, such as a rubber sealing ring, is provided between the slide plate 201 and the inner wall of the bottom tube 2 to prevent water from leaking from the gap between the slide plate 201 and the bottom tube 2.

[0044] A connecting post 102 is fixedly connected to the bottom of the floating plate 101. Connecting post 102 sequentially passes through the water reservoir 1 and the slide plate 201. A vertical plate 205 is fixedly connected to the bottom of the slide plate 201. A second rack 204 is fixedly connected to the vertical plate 205. Rack 1 202 is fixedly connected to the outer periphery of the connecting post 102. A gear 203 is rotatably connected to the bottom barrel 2, located between rack 1 202 and rack 2 204. Connecting post 102 is made of metal, such as stainless steel, with its diameter and length determined by the dimensions of the floating plate 101 and the installation space of the bottom barrel 2. Connecting post 102 sequentially passes through the bottom of the water reservoir 1 and the slide plate 201. Through holes matching the connecting post 102 are provided in the bottom of the water reservoir 1 and the slide plate 201. A sealed bearing is provided between the through hole and the connecting post 102 to ensure free sliding of the connecting post 102 while preventing water leakage.

[0045] The anti-floating plate 3 13 is fixedly connected to the vertical plate 205, and a movable groove 207 is opened on the outer periphery of the bottom tube 2, and the anti-floating plate 3 13 slides in the movable groove 207; a protective cover 131 is fixedly connected to the outer periphery of the bottom tube 2, and the anti-floating plate 3 13 is located in the protective cover 131. The protective cover 131 can protect the anti-floating plate 3 13 from the influence of the external environment, and at the same time prevent debris from entering the movable groove 207 and affecting the sliding of the anti-floating plate 3 13.

[0046] There are four anti-floating plates 11, 2 anti-floating plates 12, 3 anti-floating plates 13 and 14 arranged around the circumference.

[0047] When installing the device, first, a suitable foundation pit is excavated below the basement, and the water storage tank 1 and the bottom tube 2 are buried in the foundation pit. The water storage tank 1 and the bottom tube 2 are then fixed and positioned to prevent displacement. The anchor pile 150 is sequentially inserted through the insertion holes 111 and the collar 144 on the anti-floating plate 1 11, the anti-floating plate 2 12, and the anti-floating plate 3 13. During the insertion process of the anchor pile 150, the limiting claw 153 retracts into the installation groove 151 when it contacts the anti-floating plate 1 11, the anti-floating plate 2 12, the anti-floating plate 3 13, and the collar 144, allowing the anchor pile 150 to be smoothly inserted into the foundation. When the anchor pile 150 is inserted to a preset depth, the limiting claw 153 is located below the anti-floating plate 1 11, the anti-floating plate 2 12, the anti-floating plate 3 13, and the collar 144, and is deployed under the elastic force of the spring sheet 152, thereby limiting the upward movement of the anchor pile 150.

[0048] When the water level around the basement rises, the groundwater has a floating effect on the basement structure. Since the anchor piles 150 are inserted into the foundation, the anchor piles 150 can provide a certain pulling force to prevent the basement from floating.

[0049] In addition, when the anchor pile 150 is subjected to an upward pulling force, the multiple groups of claw assemblies 15 on the anchor pile 150 respectively press against the anti-floating plate 11, the anti-floating plate 2 12, the anti-floating plate 3 13, and the ring 144, thereby hindering the floating of the anchor pile 150 and thereby improving the anti-floating performance.

[0050] Groundwater enters reservoir 1 through inlet hole 10, gradually raising the water level in reservoir 1. As the water level rises, the buoyancy on float plate 101 increases, causing float plate 101 to begin to move upward. This upward movement of float plate 101 drives connecting column 102 upward, which in turn causes rack 1 202 on connecting column 102 to move upward. Because rack 1 202 meshes with gear 203, gear 203 begins to rotate, driving rack 2 204 downward. Because rack 204 is fixed to vertical plate 205, which is fixedly connected to anti-floating plate 3 13, anti-floating plate 3 13 moves downward with vertical plate 205, pressing down on anchor pile 150, providing downward pressure on anchor pile 150 and increasing the basement's anti-floating capacity.

[0051] When floating plate 101 is able to float upward, it indicates a high level of groundwater. Therefore, the upward movement of floating plate 101 causes slide plate 201 to move downward, thereby increasing the volume of water reservoir 1 and bottom cylinder 2 between floating plate 101 and slide plate 201, thereby increasing the water storage capacity and preventing groundwater from leaking into the basement. Therefore, this device can automatically adjust the water storage capacity based on the amount of groundwater. While adjusting the water storage capacity, it can also coordinate with vertical plate 205 to drive anti-floating plate 3 13 downward, exerting downward pressure on anchor pile 150 and enhancing the basement's anti-floating ability.

[0052] In addition, the circumferentially arranged anti-floating plate 11, anti-floating plate 2 12, anti-floating plate 3 13, and anti-floating pipe 14 are located in the foundation and are placed horizontally in the foundation to increase the contact area and further improve the anti-floating ability of the basement.

[0053] A sleeve rod 141 is slidably connected to the anti-floating tube 14, and the two ends of the sleeve rod 141 are fixedly connected to a connecting rod 143 and an insertion rod 142 respectively. The connecting rod 143 is fixedly connected to the collar 144, and a spring 145 is sleeved on the connecting rod 143. One end of the spring 145 is fixedly connected to the front end of the anti-floating tube 14, and the other end is fixedly connected to the sleeve rod 141; a slot 206 is opened at the lower end of the vertical plate 205, and the insertion rod 142 corresponds to the slot 206.

[0054] When the insertion rod 142 is against the vertical plate 205, the spring 145 is in a charged state. When the vertical plate 205 moves downward so that the slot 206 is opposite to the insertion rod 142, the spring 145 pushes the sleeve rod 141 so that the insertion rod 142 is inserted into the slot 206. At this time, the connecting rod 143 generates a lateral pulling force on the anchor pile 150, so that the anchor pile 150 is tightly combined with the foundation, the water storage tank 1, and the bottom tube 2, further preventing the anchor pile 150 from floating up, and effectively enhancing the anti-floating ability of the basement.

[0055] Example 2: Reference Figure 5 A device for preventing basement floor slab from floating and leaking is basically the same as Example 1, further comprising: a liquid level sensor is provided in the water storage tank 1, a bracket is fixedly connected to the top wall of the water storage tank 1, a pressure sensor is mounted on the bracket, the pressure sensor corresponds to the floating plate 101, and the liquid level sensor and the pressure sensor are used to monitor the liquid level in the water storage tank 1 and the position of the floating plate 101.

[0056] When the device automatically adjusts the water storage capacity according to the amount of groundwater, the liquid level sensor detects the water amount in the water storage tank 1, the PLC controller automatically controls the pumping power of the water pump, and the pressure sensor prevents the floating plate 101 from floating excessively.

[0057] In addition, when the liquid level sensor detects a low water level, but the pressure sensor detects the pressure of the float 101 on it, it can be determined that a large amount of water in the water storage tank 1 has overflowed into the space above the float 101. At this time, an external water pump can be connected to the connecting pipe 3 to pump water into the space between the float 101 and the bottom of the water storage tank 1, so that the float 101 floats normally.

[0058] It should be understood that an exhaust pipe is provided above the water storage tank 1 to discharge gas or water.

[0059] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
