Description

Technical Field

[0001] This utility model relates to the field of centralized drainage and seepage prevention in basements. More specifically, this utility model relates to a centralized drainage and seepage prevention structure for basements. Background Technology

[0002] With the increasing number of private cars, basements have become standard in most residential communities to ensure sufficient parking spaces and green space ratios. Building planting and landscaping projects on basement roofs is now commonplace. However, due to unreasonable design, substandard construction, weakened concrete impermeability over time, or leaks persisting even after sealing due to pipework for building equipment, basement roof leaks are a recurring problem. Minor leaks affect aesthetics and lead to complaints; serious leaks directly impact the normal use of underground parking garages, causing extremely negative social consequences. Basement roof leaks remain one of the long-standing unresolved problems in construction engineering.

[0003] Currently, waterproofing basement roofs has become an important aspect of architectural engineering design and construction discussions. Methods for repairing basement leaks include: 1. Generally, this involves excavating the roof slab, filling cracks in the roof structure with grout, and reinstalling waterproofing measures. This method is effective, but its disadvantages include long construction time, large work area, and lack of economy; 2. Grouting cracks to seal leaks in the roof slab. This is effective in the short term, but because the water stagnant on the upper layer of the roof slab is not drained, new leaks will form in other parts of the basement over time.

[0004] To address the issue of small-scale water seepage in the aforementioned basement, a new type of centralized drainage and seepage-resistant structure for basements is needed. Utility Model Content

[0005] To achieve these objectives and other advantages according to the present invention, a preferred embodiment of the present invention provides a centralized drainage and seepage prevention structure for basements, comprising at least one drainage and seepage prevention component. At least one opening is formed in the basement roof slab, and a drainage and seepage prevention component is correspondingly provided at each opening. The drainage and seepage prevention component comprises:

[0006] The pipe body penetrates the basement roof slab through an opening, and the space between the outer wall of the pipe body and the wall of the opening is filled with asphalt hemp fibers.

[0007] A seepage blind pipe is located above the basement ceiling. The seepage blind pipe is sleeved on the top of the pipe body. The inner diameter of the seepage blind pipe is larger than the outer diameter of the pipe body, and the gap between the two is sealed with sealant.

[0008] A water-cutting baffle tray is arranged in a ring around one end of the pipe body, and the water-cutting baffle tray is located on the bottom surface of the basement ceiling. The bottom of the water-cutting baffle tray is connected to the pipe body through a floor drain connection pipe.

[0009] Preferably, the finished drainage blind pipe extends into the soil layer above the basement roof slab.

[0010] Preferably, the opening diameter in the basement roof slab is 50mm larger than the outer diameter of the pipe.

[0011] Preferably, a flange is also provided, which is annularly sleeved on the outside of the pipe body. The flange is anchored to the bottom surface of the basement roof slab by chemical bolts, and a rubber gasket is pressed between the flange and the bottom surface of the basement roof slab.

[0012] Preferably, the gap between the water-cutting baffle tray and the pipe body is filled with a waterproof sealing layer.

[0013] Preferably, the water-cutting baffle tray is annular, with the side closer to the pipe being higher and the side farther from the pipe being lower.

[0014] Preferably, the pipe bodies of the flow-guiding and seepage-resistant components are all connected to the same flow-guiding pipe, which is then connected to the water collection pit.

[0015] This invention offers at least the following advantages: Through the synergistic effect of the pipe body, the seepage blind pipe, and the water-stopping baffle tray, it forms multiple waterproof and drainage barriers, efficiently collecting and draining seepage water from above the basement ceiling. This invention enhances seepage resistance reliability, expands the seepage collection range, improves construction and maintenance convenience, ensures a dry and stable interior for the basement, and provides a favorable environment for basement use.

[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] like Figure 1-3 As shown, a preferred embodiment of this utility model provides a centralized drainage and seepage prevention structure for a basement, including at least one drainage and seepage prevention component. At least one opening is formed in the basement roof slab, and a drainage and seepage prevention component 1P is correspondingly provided at each opening. The drainage and seepage prevention component 1P includes:

[0023] Pipe 7, which penetrates the basement roof slab 11 through an opening in the basement roof slab 11, with asphalt hemp fiber 3 filling the space between the outer wall of the pipe 7 and the wall of the opening.

[0024] A seepage blind pipe 1 is located above the basement ceiling. The seepage blind pipe 1 is sleeved on the top of the pipe body 7. The inner diameter of the seepage blind pipe is larger than the outer diameter of the pipe body 7. The gap between the two is sealed with sealant 2.

[0025] A water-cutting baffle tray 5 is arranged in a ring around one end of the pipe body 7, and the water-cutting baffle tray 5 is located on the bottom surface of the basement roof slab. The bottom of the water-cutting baffle tray 5 is connected to the pipe body 7 through a floor drain connecting pipe 9.

[0026] In the above technical solution, when there is water seepage above the basement ceiling, the seepage water is first collected by the seepage blind pipe 1 located above the ceiling. The water can enter the blind pipe 1 and then flow along the seepage blind pipe 1 to the pipe body 7, and then flow downward through the pipe body 7. At the same time, if a small amount of water seeps out from the gap between the pipe body 7 and the opening wall, it will be caught by the water interception baffle tray 5 located on the bottom surface of the basement ceiling. The water in the water interception baffle tray 5 flows into the pipe body 7 through the floor drain connection pipe 9 under the action of gravity. Finally, all the water entering the pipe body 7 is concentrated and guided to the designated drainage system for discharge, thereby achieving centralized diversion and seepage prevention of the basement.

[0027] The drainage and seepage-resistant component of this application can effectively collect seepage water above the basement roof and guide it out, preventing seepage water from penetrating into the basement. The synergistic effect of the asphalt hemp fiber 3 between the pipe body 7 and the opening wall, the sealant 2 between the seepage blind pipe 1 and the pipe body 7, and the water-stopping baffle tray 5 forms multiple waterproof and drainage barriers, greatly reducing the possibility of seepage water entering the basement, improving the basement's seepage resistance, and ensuring the dryness and stability of the basement's internal environment.

[0028] In another technical solution, the finished seepage blind pipe 1 extends into the soil layer above the basement roof slab.

[0029] In the above technical solution, extending the prefabricated seepage blind pipe 1 into the backfill layer allows for direct collection of moisture from the backfill layer, preventing excessive moisture accumulation and seepage into the basement roof slab, thereby further reducing the risk of seepage into the basement. This design extends seepage collection from the basement roof surface into the interior of the backfill layer, expanding the scope and depth of seepage collection and improving the control over moisture in the backfill layer.

[0030] In another technical solution, the opening diameter of the basement roof slab is 50mm larger than the outer diameter of the pipe body 7.

[0031] In the above technical solution, the setting that the opening diameter of the basement roof slab is 50mm larger than the outer diameter of the pipe body 7 not only provides sufficient space for the filling of asphalt hemp fiber 3, ensuring the compactness and waterproof effect of the filling, but also improves the convenience of construction and subsequent maintenance.

[0032] In another technical solution, a flange is also provided, which is annularly sleeved on the outside of the pipe body 7. The flange 6 is anchored to the bottom surface of the basement roof slab 11 by chemical bolts 10, and a rubber gasket 4 is pressed between the flange 6 and the bottom surface of the basement roof slab.

[0033] In the above technical solution, the flange 6, through the anchoring effect of the chemical bolts 10, effectively enhances the installation stability of the pipe body 7 on the basement roof slab 11, preventing the pipe body 7 from shifting due to external forces and ensuring the integrity of the entire anti-seepage structure. The seal formed by the rubber gasket 4 under the compression of the flange 6 further prevents water leakage from the gap between the flange 6 and the bottom surface of the basement roof slab 11.

[0034] In another technical solution, the gap between the water-blocking baffle support and the pipe body 7 is filled with a waterproof sealing layer 8.

[0035] In the above technical solution, the waterproof sealing layer 8 completely seals the gap between the water intercepting baffle tray 5 and the pipe body 7, ensuring that all the water received by the water intercepting baffle tray 5 can be discharged through the floor drain connection pipe 9 into the pipe body 7, thereby improving the diversion efficiency of the water intercepting baffle tray 5.

[0036] In another technical solution, the water-cutting baffle tray 5 is annular, with the side closer to the pipe body 7 being higher and the side farther from the pipe body 7 being lower.

[0037] In the above technical solution, the high and low structure design of the water interception baffle tray 5 uses gravity to accelerate the flow and collection of seepage water, improves the efficiency of guiding seepage water, avoids water accumulation and overflow on the tray, and ensures that the water interception baffle tray 5 can more effectively guide the received seepage water into the pipe body 7 for discharge.

[0038] In another technical solution, the pipe body of the flow-guiding and seepage-resistant component 1P is connected to the same flow-guiding pipe 12, which is then connected to the water collection pit.

[0039] In the above technical solution, connecting all pipes 7 to the same diversion pipe and then to the sump allows for centralized and unified treatment of basement seepage, avoiding the problems of messy pipes and low drainage efficiency caused by individual drainage of each pipe 7. The reasonable pipe diameter and slope design of the diversion pipe ensures smooth water flow and reduces the risk of blockage; the centralized collection in the sump and the timely drainage by the drainage pump further improve the reliability of drainage.

[0040] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
