Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology in building engineering, and more specifically, to a waterproofing structure for underground garages. Background Technology

[0002] Underground parking garages refer to parking spaces designed and built in underground or semi-underground spaces. As an important part of modern urban planning and architectural design, they have multiple characteristics and functions. In the construction of underground parking garages, pipes (such as water supply and drainage pipes, HVAC pipes, etc.) often need to pass through the roof slab for connection.

[0003] Pipe crossings are often weak points in waterproofing, often resulting in poor sealing and easy leakage under external forces. This can lead to problems such as dampness inside the garage, mold on the walls, and water accumulation on the floor, seriously affecting the garage's lifespan and safety.

[0004] Therefore, we made improvements and proposed a waterproof structure for underground parking garages. Utility Model Content

[0005] The purpose of this utility model is to address the fact that pipe penetration points are often weak points in waterproofing, often have poor sealing, and are prone to leakage under external forces, leading to problems such as dampness inside the garage, mold on the walls, and water accumulation on the floor, which seriously affects the service life and safety of the garage.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0016] As a preferred embodiment of the underground garage waterproof structure provided by this utility model, the waterproof material layer is a modified bitumen waterproof membrane.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0035] Example 1

[0036] Please refer to Figure 1-2 The underground garage waterproof structure includes a base surface 1. A retaining wall 11 is fixedly installed on one side of the outer surface of the base surface 1. Two waterproof material layers 12 are fixedly installed between the outer surfaces of the base surface 1 and the retaining wall 11. A reinforced concrete self-waterproofing protective layer 13 is fixedly installed on the upper surface of one of the waterproof material layers 12. A pipe 1 2 is fixedly installed inside the reinforced concrete self-waterproofing protective layer 13. A pipe 21 is fixedly installed inside the reinforced concrete self-waterproofing protective layer 13 on one side of the pipe 1 2. One end of the pipe 21 is fixedly connected to the pipe 1 2. A sealing element is fixedly installed on the upper surface of the pipe 21. The sealing element includes a sealing ring 22. The lower surface of the sealing ring 22 is fixedly connected to pipe 21 and reinforced concrete self-waterproofing protective layer 13, respectively. A manhole cover 23 is slidably connected to the upper surface of the reinforced concrete self-waterproofing protective layer 13. A connecting frame 24 is fixedly connected to the lower surface of the manhole cover 23. Several filter holes 25 are opened on the outer surfaces of both the manhole cover 23 and the connecting frame 24. The connecting frame 24 is slidably set on the inner surface of pipe 21 and the outer surface of the sealing ring 22, respectively. An annular slot is opened on the upper surface of the reinforced concrete self-waterproofing protective layer 13 outside the sealing ring 22. A sealing gasket 26 is slidably connected to the inner bottom surface of the annular slot. An insert ring 27 is fixedly connected to the lower surface of the manhole cover 23 and is slidably set inside the annular slot. Four threaded rods 28 are threadedly connected between the manhole cover 23 and the reinforced concrete self-waterproofing protective layer 13. Steel sleeves 3 are installed on the outer surfaces of both pipe 21 and pipe 22. Water-stop rings 31 are installed on the outer surfaces of both steel sleeves 3.

[0037] Implementation process: Rainwater falls into the interior of pipe 21 through the filter holes 25 on the surface of manhole cover 23 and connecting frame 24, and then is discharged through pipe 2. During the flow of rainwater, the interface between pipe 21 and reinforced concrete self-waterproofing protective layer 13 is sealed by sealing ring 22, the interface between sealing ring 22 and pipe 21 is sealed by connecting frame 24, and the interface between reinforced concrete self-waterproofing protective layer 13 and manhole cover 23 is sealed again by sealing gasket 26. At the same time, the setting of steel sleeve 3 and water-stop ring 31 can effectively prevent rainwater from seeping into the gap between pipe 21 and steel sleeve 3, greatly improving the sealing and waterproof performance.

[0038] Benefits of implementation: Significantly improves sealing and waterproofing.

[0041] Implementation process: The chamfer 14 is made of cement mortar, and a layer of polymer waterproof coating is applied to the upper surface of the chamfer 14. The waterproof material layer 12 is made of modified bitumen waterproof membrane and laid on the surface of the base 1, the retaining wall 11 and the chamfer 14. At the same time, the reinforced concrete self-waterproof protective layer 13 itself has a certain degree of waterproofness, which can effectively prevent water from seeping into the interior of the basement.

[0042] Benefits of implementation: It can effectively prevent water from seeping into the interior of the basement.
