Description

Technical Field

[0001] The utility model relates to the field of building pressure stabilization and anti-floating, in particular to a building groundwater pressure stabilization and anti-floating structure. Background Art

[0002] With the development of urban economy and the increase of population density, more and more super high-rise buildings are springing up. In order to ensure people's living needs, while the height of buildings is rising, the expansion and utilization of underground space has also become a major trend. Nowadays, the basements of super high-rise buildings generally have the characteristics of large area, large span and large depth. The floor elevation is often more than ten or even twenty meters below the ground surface. According to investigation and data research, the basements of super high-rise buildings generally have the quality risk of rising groundwater level due to surface water infiltration and other reasons, and the floor is subject to increased water pressure, resulting in floating and cracking of the floor, which seriously affects the use of the building.

[0003] In order to prevent the rising groundwater from causing damage to buildings, many holes need to be drilled on the outer walls and the floor to ensure that the groundwater can be completely pumped out to achieve the effect of groundwater pressure stabilization. However, the large number of drainage holes on the outer walls and the floor will have a certain impact on the building, and such drainage holes are prone to the risk of siltation and blockage over a long period of time, requiring regular manual maintenance, which greatly increases the workload of subsequent staff.

[0004] In summary, the large number of drainage holes on the outer wall and the bottom plate of the above structure will have a certain impact on the building during use, and the drainage holes are very likely to cause the risk of siltation and blockage over a long period of time, greatly increasing the workload of subsequent staff. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a groundwater pressure-stabilizing and anti-floating structure for a building, so as to solve the technical problem that a large number of drainage holes on the outer wall and the bottom plate will have a certain impact on the building, and the drainage holes are very likely to cause siltation and blockage over a long period of time, greatly increasing the workload of subsequent staff.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a groundwater pressure-stabilizing and anti-floating structure of a building, comprising a base plate, an array of through holes is arranged on the base plate, a seepage cylinder is detachably arranged inside the through hole, an array of seepage holes is evenly arranged on the upper part of the outer wall of the seepage cylinder, a floating plate is slidably arranged inside the seepage cylinder, a drainage hole is penetrated through the bottom of the seepage cylinder at the bottom of the floating plate, and a drainage pipe is connected to one end of the drainage hole, a water collecting trough is arranged on the base plate at the other end of the drainage pipe, and a water retaining plate is slidably arranged at the bottom of the floating plate at the drainage hole.

[0007] By adopting the above technical scheme, when the groundwater pressure is too high and the water level rises, it will enter the seepage barrel through the seepage holes to ensure the stability of the groundwater pressure. When the groundwater pressure is too low, it will not seep into the seepage barrel, thereby ensuring that the groundwater pressure will not be too high or too low. When the floating plate drives the water retaining plate to float upward, the drainage hole will be completely exposed. At this time, the groundwater in the seepage barrel will be discharged into the sump through the drainage pipe, which is convenient for subsequent staff to extract it regularly. During this process, the drainage hole is inside the seepage barrel, and the groundwater is filtered through the seepage hole, which effectively improves the blockage of the drainage hole, thereby extending the cleaning cycle of the staff.

[0008] The utility model is further configured that the water seepage cylinder is provided with an inner groove for sliding at the water retaining plate.

[0009] By adopting the above technical solution, the inner groove facilitates the water retaining plate to slide up and down inside the water seepage cylinder. At the same time, the cooperation between the inner groove and the water retaining plate can improve the sealing of the drainage hole, effectively preventing groundwater leakage.

[0010] The utility model is further configured that the inner wall of the water seepage cylinder is symmetrically provided with sliding grooves, and the outer side of the floating plate is provided with sliding blocks that cooperate with the sliding grooves.

[0011] By adopting the above technical solution, the stability of the floating plate sliding up and down in the water seepage cylinder is ensured through the cooperation of the slider and the slide groove, and the floating plate is prevented from sliding left and right.

[0012] The utility model is further configured that a compression spring is arranged inside the slide groove, and the other end of the compression spring is connected to the sliding block.

[0013] By adopting the above technical scheme, the floating plate can be prevented from tilting up and down in the seepage cylinder under the action of the compression spring, thereby preventing the water retaining plate from getting stuck in the inner groove. At the same time, the elastic force of the compression spring is smaller than the buoyancy of the floating plate in the seepage cylinder. When groundwater accumulates in the seepage cylinder, the compression spring can be stretched. When the groundwater is subsequently discharged, the drainage hole can be quickly blocked to prevent the groundwater from flowing back.

[0014] The utility model is further configured that one side of the water collecting tank is connected to the outside through a water pipe.

[0015] By adopting the above technical solution, it is convenient for subsequent staff to regularly pump out groundwater in the sump to prevent leakage due to long-term accumulation.

[0016] The utility model is further configured such that the water seepage hole is configured to be wide outside and narrow inside.

[0017] By adopting the above technical solution, the wide outer side facilitates the penetration of groundwater into the seepage tube, and the narrow inner side facilitates the filtering of impurity particles carried by the groundwater, thereby preventing the infiltrated groundwater from clogging the drainage pipe and reducing the cleaning frequency of the staff.

[0018] The utility model is further configured such that the diameter of the floating plate is smaller than the diameter of the water seepage cylinder, and the outer wall of the floating plate is configured in an arc shape.

[0019] By adopting the above technical solution, when groundwater seeps in, it can flow to the bottom of the seepage tube through the edge, preventing water from accumulating on the top of the floating plate. At the same time, the arc-shaped setting of the floating plate makes it easier for groundwater accumulated on the top to slide to the bottom of the seepage tube.

[0020] The utility model is further configured such that the slider and the slide groove are arranged in a smooth shape.

[0021] By adopting the above technical solution, the sliding friction between the two is reduced, preventing the buoyancy of the groundwater from failing to lift up the floating plate, and ensuring the stability of the floating plate sliding up and down.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] 1. The utility model reduces its own impact on the building by arranging through holes on the bottom plate, and the spacing between each group of through holes is large. At the same time, a water seepage cylinder is arranged in the through hole, and a group of water seepage holes is arranged on the upper part of the water seepage cylinder. When the groundwater pressure is too high and the water level rises, it will enter the water seepage cylinder through the water seepage holes to ensure the stability of the groundwater pressure. When the groundwater pressure is too low, it will not penetrate into the water seepage cylinder, thereby ensuring that the groundwater pressure will not be too high or too low;

[0024] 2. The utility model provides a floating plate in the seepage cylinder. When groundwater seeps into the seepage cylinder, the floating plate will float upward. At the same time, a water retaining plate is provided at the bottom of the floating plate. When the floating plate drives the water retaining plate to float upward, the drainage hole will be completely exposed. At this time, the groundwater in the seepage cylinder will be discharged into the sump through the drainage pipe, which is convenient for subsequent staff to extract it regularly. During this process, the drainage hole is inside the seepage cylinder, and the groundwater is filtered through the seepage hole, which effectively improves the blockage of the drainage hole, thereby extending the cleaning cycle of the staff and reducing the subsequent cleaning burden.

[0030] 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.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] Embodiment 1

[0033] A building groundwater pressure stabilizing and anti-floating structure, such as Figure 1-Figure 3 As shown, it includes a bottom plate 1, a water seepage cylinder 3, a drainage mechanism and a sliding mechanism. An array of through holes 2 is evenly arranged on the top of the bottom plate 1, and the spacing between each group of through holes 2 is large, so as to reduce the impact on the building, and a water seepage cylinder 3 is arranged inside the through hole 2, and an array of water seepage holes 4 are evenly arranged on the upper part of the outer wall of the water seepage cylinder 3. When the groundwater pressure is too high and the water level rises, it will enter the water seepage cylinder 3 through the water seepage holes 4 to ensure the stability of the groundwater pressure. When the groundwater pressure is too low, it will not penetrate into the water seepage cylinder 3, so as to ensure that the groundwater pressure will not be too high or too low. The phenomenon of low water level is eliminated, and the seepage hole 4 on the outer wall of the seepage cylinder 3 is arranged with a wide outer side and a narrow inner side. The wide outer side facilitates the groundwater to penetrate into the seepage cylinder 3, and the narrow inner side facilitates the filtering of impurity particles carried by the groundwater, thereby preventing the infiltrated groundwater from clogging the drainage pipe 8 and reducing the cleaning frequency of the staff. The diameter of the floating plate 7 is smaller than the diameter of the seepage cylinder 3, and the outer wall of the floating plate 7 is arranged in an arc shape. When groundwater penetrates, it can flow to the bottom of the seepage cylinder 3 through the edge, thereby preventing water from accumulating on the top of the floating plate 7. At the same time, the arc-shaped arrangement of the floating plate 7 facilitates the groundwater accumulated on the top to slide to the bottom of the seepage cylinder 3.

[0034] At the same time, a floating plate 7 is slidingly provided inside the seepage cylinder 3, and a drainage hole 12 is penetrated through the bottom of the floating plate 7 on the seepage cylinder 3, and a drainage pipe 8 is connected to one end of the drainage hole 12, and a water collecting trough 9 is provided on the bottom plate 1 at the other end of the drainage pipe 8, wherein a water retaining plate 10 is sliding up and down at the bottom of the floating plate 7 at the drainage hole 12. When the groundwater pressure is too high, the groundwater penetrates into the seepage cylinder 3 through the seepage hole 4. At this time, the buoyancy force will drive the floating plate 7 to slide upward. In this process, the water retaining plate 10 at the bottom will slide upward with the floating plate, so that the water retaining plate 10 releases the blockage of the drainage hole 12, so that the drainage hole is completely exposed. At this time, the groundwater in the seepage cylinder will be discharged into the water collecting trough through the drainage pipe, which is convenient for subsequent staff to extract it regularly.

[0035] See also Figure 2 and Figure 3 An inner groove 11 for sliding is provided on the water seepage cylinder 3 at the water baffle plate 10. The inner groove 11 facilitates the water baffle plate 10 to slide up and down inside the water seepage cylinder 3. At the same time, the cooperation between the inner groove 11 and the water baffle plate 10 can improve the sealing of the drainage hole 12, effectively preventing groundwater leakage.

[0036] See also Figure 2 and Figure 3 The inner wall of the water seepage cylinder 3 is symmetrically provided with a slide groove 5, and the outer side of the floating plate 7 is provided with a slider 6 that cooperates with the slide groove 5. The cooperation between the slider 6 and the slide groove 5 ensures the stability of the floating plate 7 sliding up and down in the water seepage cylinder 3, and prevents the floating plate 7 from sliding left and right. In addition, the slider 6 and the slide groove 5 are arranged in a smooth shape to reduce the sliding friction between the two, prevent the floating plate 7 from being unable to lift up the buoyancy of the groundwater, and ensure the stability of the floating plate 7 sliding up and down.

[0037] Embodiment 2

[0038] See also Figure 4 The shown structure is a groundwater pressure-stabilizing and anti-floating structure for a building, and its overall structure is similar to that of the first embodiment. A compression spring 13 is arranged inside the slide groove 5, and the other end of the compression spring 13 is connected to the slider 6. Under the action of the compression spring 13, the floating plate 7 can be prevented from tilting up and down in the seepage cylinder 3, thereby preventing the water retaining plate 10 from getting stuck in the inner groove 11. At the same time, the elastic force of the compression spring 13 is less than the buoyancy of the floating plate 7 in the seepage cylinder 3. When groundwater accumulates in the seepage cylinder 3, the compression spring 13 can be stretched. When the groundwater is subsequently discharged, the drainage hole 12 can be quickly blocked to prevent the groundwater from flowing back.

[0039] The working principle of the utility model is as follows: when in use, an array of through holes 2 is provided on the bottom plate 1, and the spacing between the through holes 2 is large, so as to reduce the impact on the building. Through the internal seepage cylinder 3, and an array of seepage holes 4 is provided on the upper part of the seepage cylinder 3, when the groundwater pressure is large, the water level rises, so that the groundwater is discharged into the seepage cylinder 3 through the seepage holes 4, so as to prevent the groundwater from floating and affecting the building. At the same time, when the groundwater pressure is too small, the groundwater will not be discharged into the seepage cylinder 3, so as to achieve a long-term stable groundwater pressure. The seepage cylinder 3 is in a fixed state, and a floating plate 7 is arranged in the seepage cylinder 3. When the groundwater is discharged into the seepage cylinder 3, the floating plate 7 will be driven to float upward, thereby driving the water retaining plate 10 to open the drainage hole 12. At this time, the infiltrated groundwater is uniformly discharged into the water collecting tank 9 on one side, which is convenient for subsequent staff to uniformly extract. Moreover, the drainage hole 12 is inside the seepage cylinder 3. The groundwater in the seepage cylinder 3 carries very few impurity particles after being filtered through the seepage hole 4, which effectively improves the blockage of the drainage hole 12, thereby extending the cleaning cycle of the staff.
