Description

Technical Field

[0001] This utility model relates to a structure for preventing toxic gas penetration in civil defense basements. Background Technology

[0002] As an important wartime protection facility, the ability to prevent the penetration of toxic gases is a core requirement in the design and construction of civil defense basements. Among these requirements, the gas penetration prevention of wall penetration holes is particularly important. These holes are mainly used for installing cables, water pipes, etc. To facilitate installation, their diameter is generally slightly larger than the diameter of the cables and water pipes, which creates gaps. Traditionally, sealing gaps are sealed with sealing rings or fillers. Sealing rings tend to age and harden after a period of use, and while fillers solidify and fill the gaps, thermal expansion and contraction, as well as potential earthquakes, explosions, and other shocks can cause the fillers to crack, affecting the sealing performance. Utility Model Content

[0003] The purpose of this utility model is to provide a gas-proof structure for civil defense basements, which can not only automatically adapt to filling and play a good sealing role when the concrete deforms due to earthquakes or thermal expansion and contraction, but also can be stored for a long time without failing.

[0004] The technical solution of this utility model is as follows: A gas-proof structure for use in civil defense basements, comprising: The wall has through holes for installing cables or pipes, and a sealing ring is provided at one end of the through hole; A grease storage container has an opening at the bottom, and a sealing film is attached to the opening. The sealing film is connected to a peeling strip, and the sealing film can be peeled off from the opening by pulling the peeling strip in a set direction. The mounting hole is located on the side wall of the wall near the basement and above the through-wall hole. The external dimensions of the through-wall hole are the same as those of the grease storage tank. A grease collection groove is provided on the bottom surface of the through-wall hole corresponding to the opening. A grease supply hole is provided at the bottom of the grease collection groove and is connected to the through-wall hole.

[0005] The beneficial effects of this technical solution are as follows: In the use of a gas-proof structure for a civil defense basement, the grease storage container is normally placed face down in the installation hole, with a sealing film affixed to the opening to keep the grease storage container sealed. This ensures the grease can be stored for several years. For example, synthetic oil-based grease can be sealed and stored for 5-10 years without deterioration. This application utilizes its semi-fluid state to achieve a seal on the wall penetration hole, so even if it deteriorates, it can still be used for a period of time. When the civil defense basement is needed, personnel sheltering inside can... By peeling off the sealing film from the opening using the pull strip, the opening of the grease storage container is opened. The grease inside can then slowly flow downwards under its own weight into the grease collection tank, and then enter the wall penetration hole through the grease supply hole, filling the gap between the cable, pipe, etc. and the wall penetration hole. Due to the viscosity and slow flow of the grease, it can remain in the wall penetration hole for a long time without flowing out. When the concrete expands and contracts due to heat, or when an earthquake or explosion occurs, the grease will also adaptively fill newly formed cracks or self-seal. Moreover, a new grease storage container can be replaced for subsequent use. It is easy to see that this solution can adaptively seal the wall penetration hole in scenarios such as earthquakes, explosions, and concrete expansion and contraction deformation, preventing toxic gases from penetrating into the civil defense basement. Furthermore, the sealing film is only removed when the civil defense basement is in use, ensuring that the grease can be stored for a long time. It is also convenient and quick to operate and replace.

[0006] Based on the above solution, the following improvement is made: the sealing ring is set at the end of the wall penetration hole near the basement.

[0007] Based on the above solution, the following improvements are made: the length of the pull bar is greater than the diameter of the grease reservoir, so that one end of the pull bar can be folded over and protrude from the mounting hole.

[0008] Based on the above solution, the following improvements are made: one end of the pull strip extending from the mounting hole is provided with a pull hole for fingers to pass through.

[0009] Based on the above solution, the following improvements are made: the sealing film and the peeling strip are made of the same material in one piece.

[0010] Based on the above solution, the following improvements are made: both the grease container and the corresponding mounting hole are rectangular.

[0011] Based on the above scheme, the following improvements are made: the grease in the grease storage tank is a synthetic oil-based grease. Attached Figure Description

[0016] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0017] A specific embodiment of the gas-proof structure for civil defense basements according to this utility model is as follows: Figure 1-3As shown, the gas penetration prevention structure for the civil defense basement includes a wall 1, with a through hole 11 for installing cables 5 or pipes on the wall 1. A sealing ring 2 is provided at one end of the through hole 11. The sealing ring 2 is located at the end of the through hole 11 closest to the basement.

[0018] The lower end of the grease reservoir 3 has an opening 31, and a sealing film 4 is affixed to the opening 31. A peeling strip 41 is connected to the sealing film 4. By pulling the peeling strip 41 in a predetermined direction, the sealing film 4 can be peeled off from the opening 31. The length of the peeling strip 41 is greater than the diameter of the grease reservoir 3, so that one end of the peeling strip 41 is folded over and extends out of the mounting hole 12. The end of the peeling strip 41 extending out of the mounting hole 12 has a pull hole 411 for a finger to pass through. The sealing film 4 and the peeling strip 41 are made of the same material in one piece.

[0019] The mounting hole 12 is located on the side wall of wall 1 near the basement, above the through-wall hole 11. The through-wall hole 11 has the same dimensions as the grease storage tank 3. A grease collection groove 13 is provided on the bottom surface of the through-wall hole 11 corresponding to the opening 31. A grease supply hole 14 is provided at the bottom of the grease collection groove 13, and the grease supply hole 14 communicates with the through-wall hole 11. Both the grease tank and the corresponding mounting hole 12 are rectangular. The grease in the grease storage tank 3 is a synthetic oil-based grease.

[0020] When using the gas-proof structure for civil defense basements, the grease storage tank 3 is normally placed with its opening 31 facing downwards in the mounting hole 12. A sealing film 4 is affixed to the opening 31, keeping the grease storage tank 3 sealed and ensuring the grease can be stored for several years. For example, synthetic oil-based grease can be sealed and stored for 5-10 years without deterioration. This application utilizes its semi-fluid state to seal the wall penetration hole 11, so even if it deteriorates, it can still be used for a period of time. When the civil defense basement needs to be used, personnel sheltering inside can remove the sealing film by lifting the strip 41. The membrane 4 is peeled off from the opening 31, opening 31 of the grease storage tank 3. The grease inside then flows slowly downwards under its own weight to the grease collection tank 13, and then along the grease supply hole 14 into the wall penetration hole 11, filling the gap between the cable 5, pipes, etc., and the wall penetration hole 11. Due to the viscosity and slow flow of the grease, it can remain in the wall penetration hole 11 for a long time without flowing out. When the concrete expands and contracts due to heat, or when an earthquake or explosion occurs, the grease will adaptively fill newly formed cracks or self-seal them. Furthermore, a new grease storage tank 3 can be replaced for subsequent use. It is clear that this solution can adaptively seal the wall penetration hole 11 even in scenarios such as earthquakes, explosions, and concrete thermal expansion and contraction, preventing toxic gases from penetrating into the civil defense basement. Moreover, the sealing membrane 4 is only removed when using the civil defense basement, ensuring long-term storage of the grease. The operation is convenient and quick, and replacement is also easy and quick.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
