[0002] Basements, a common building type, offer significant space utilization and functionality. However, due to their underground environment and surrounding soil and rock, they are susceptible to groundwater, rainwater, and soil moisture. Prolonged dampness in basements can not only damage the building structure, such as causing mold and peeling paint, but also affect the health of residents, potentially leading to respiratory illnesses. Therefore, the application of moisture-proof and dry-maintaining devices in basements is particularly important.

[0003] Although various moisture-proof materials and methods are available on the market, some limitations remain in practical applications. For example, traditional waterproofing materials may not completely prevent moisture penetration, especially in areas with high water tables or high soil moisture content. Ventilation and dehumidification are another important aspect of basement moisture control, and ventilation and dehumidification technologies face several challenges.

[0004] In cases where the moisture-proof structure is weak and the ventilation and dehumidification effect is poor, the wall becomes severely damp, leading to damage to the building structure and increased energy consumption of the equipment. In view of this, a moisture-proof and dry maintenance device for underground building structures is provided. Utility Model Content

[0005] The main purpose of this utility model is to provide a moisture-proof and dry maintenance device for underground building structures, so as to solve the problems of severe wall dampness leading to building structure damage and increased equipment energy consumption when the devices proposed in the related technology have thin moisture-proof structures and poor ventilation and dehumidification effects.

[0006] To achieve the above objectives, according to one aspect of this utility model, a moisture-proof and drying maintenance device for underground building structures is provided, comprising a basement wall, the inner wall of which is coated with a moisture-proof coating, a moisture-proof layer fixedly installed on the outer side of which, an insulation layer fixedly installed on one side of the moisture-proof layer, a waterproof and vapor-proof layer installed on one side of the insulation layer, and a pipe installed between the insulation layer and the waterproof and vapor-proof layer, the pipe being used to discharge moisture and introduce dry air, a guide plate for preliminary moisture prevention fixedly installed on one side of the waterproof and vapor-proof layer, and a fixed box for collecting infiltrated moisture being snapped into the bottom of the guide plate.

[0009] Furthermore, the pipe is S-shaped, with several through holes extending through the side wall of the pipe. A negative pressure suction device is installed at one end of the pipe, and a positive pressure air supply device is installed at the other end of the pipe.

[0010] Furthermore, both ends of the pipe are equipped with filter screens, which are located above the negative pressure suction device and the positive pressure air supply device, and both ends of the pipe are fitted with sealing caps.

[0011] Furthermore, the waterproof and vapor-proof layer includes a vapor-proof layer near the insulation layer and a waterproof layer fixedly connected to one side thereon. Several vent holes are provided through the vapor-proof layer, and the vent holes are inclined upwards.

[0035] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0036] Please see Figures 1-11 As shown, the purpose of this embodiment is to provide a moisture-proof and dry maintenance device for underground building structures, including a basement wall 1. The inner wall of the wall 1 is coated with a moisture-proof coating 11. A moisture-proof layer 2 is fixedly installed on the outer side of the wall 1. An insulation layer 3 is fixedly installed on one side of the moisture-proof layer 2. A waterproof and vapor-proof layer 4 is installed on one side of the insulation layer 3. A pipe 6 is installed between the insulation layer 3 and the waterproof and vapor-proof layer 4. The pipe 6 is used to discharge moisture and introduce dry air. A guide plate 7 for preliminary moisture prevention is fixedly installed on one side of the waterproof and vapor-proof layer 4. A fixed box 8 for collecting leaked moisture is snapped into the bottom of the guide plate 7.

[0037] The inner wall of wall 1 is coated with a moisture-proof coating 11, which can effectively prevent moisture inside wall 1 from seeping outward. Especially in damp environments such as basements, the moisture-proof coating 11 can significantly reduce the risk of wall 1 getting damp and keep the indoor environment dry.

[0038] The moisture-proof layer 2 is made of polyurethane, which can effectively prevent groundwater or rainwater from seeping in and protect the underground structure of the building. At the same time, its excellent breathability and moisture-proof performance can also maintain the dryness and comfort of the basement. The insulation layer 3 is made of rock wool board, which can effectively isolate the influence of external temperature on the basement and maintain a constant indoor temperature. At the same time, its fire resistance and sound absorption and noise reduction performance can also provide a safer and more comfortable living environment for the basement.

[0039] A void 5 is provided between the insulation layer 3 and the waterproof and vapor-proof layer 4. The pipe 6 is placed in the void 5, and the void 5 is filled with expanded perlite around the pipe 6. This effectively fixes and supports the pipe 6, preventing displacement or deformation of the pipe 6 due to external forces during construction, and ensuring the stability and safety of the pipe 6 during use. Expanded perlite has good thermal insulation properties, which can further enhance the thermal insulation effect of the insulation layer 3. The width of the void 5 is 5~10cm. This size range can accommodate the pipe 6 and the filling material, while maintaining sufficient space for air circulation and heat transfer. At the same time, this width range can also ensure the filling density and uniformity of the expanded perlite, thereby improving its fixing, supporting and thermal insulation performance.

[0040] The waterproof and vapor barrier layer 4 includes a vapor barrier layer 42 near the insulation layer 3 and a waterproof layer 41 fixedly connected to one side. In order to prevent the waterproof layer 41 from bulging or sinking due to air pressure difference, a number of vent holes 421 are provided through the vapor barrier layer 42 to maintain the flatness and stability of the waterproof layer 41. The vent holes 421 are inclined upwards and can also allow a very small amount of water vapor to pass through and lead it to the empty layer 5, reducing the accumulation of moisture inside the waterproof and vapor barrier layer 4 and helping to maintain the dry state of the wall 1.

[0041] The pipe 6 is S-shaped. Since a small amount of moisture flows within the empty layer 5, several through holes 61 are provided through the side wall of the pipe 6. The through holes 61 allow moisture to enter the pipe 6 from the empty layer 5. A negative pressure suction device 62 is installed at one end of the pipe 6. In this embodiment, the negative pressure suction device 62 is a vacuum pump. This device generates negative pressure to effectively extract the moisture from the pipe 6 and discharge it to the outside. A positive pressure air supply device is installed at the other end of the pipe 6 to circulate dry gas into the pipe 6. This dry gas can enter the empty layer 5 through the pipe 6 and the through holes 61, thereby reducing the humidity within the empty layer 5 and maintaining the dryness of the wall 1.

[0042] Both ends of the pipe 6 are equipped with filters 63, which are located above the negative pressure suction device 62 and the positive pressure air supply device. The main function of the filters 63 is to prevent dust, impurities and other pollutants from entering the pipe 6, thereby protecting the normal operation of the negative pressure suction device 62 and the positive pressure air supply device, and ensuring that the flowing gas is clean and dry. Both ends of the pipe 6 are also fitted with sealing caps 64. The main function of the sealing caps 64 is to protect the devices and the pipe 6 when the negative pressure suction device 62 and the positive pressure air supply device are not in use. When the negative pressure suction device 62 and the positive pressure air supply device need to be used, the sealing caps 64 can be opened to allow gas to enter or flow out of the pipe 6 through the filters 63.

[0043] The outer wall of the guide plate 7 is in contact with the soil. The guide plate 7 is made of polymer material and has a certain moisture-proof performance. It can effectively block most of the water penetration and play a preliminary moisture-proof role, but a small amount of water will still penetrate. The inner wall of the guide plate 7 has several grooves 71. The grooves 71 not only increase the inner surface area of ​​the guide plate 7, but also provide a channel for water to flow. The penetrated water can flow in the grooves 71, reducing the impact on the waterproof and vapor-proof layer 4. In addition, the bottom of the guide plate 7 is fixedly connected to a limiting strip 72.

[0044] The top of the fixed box 8 has a limiting groove 83, and the limiting strip 72 is snapped into the limiting groove 83, which can effectively resist soil pressure and external impact.

[0045] A collection box 81 is fixedly installed inside the fixed box 8. Several drain pipes 82 are inclinedly arranged on the inner wall of the fixed box 8. One end of the drain pipe 82 is connected to the limiting groove 83, and the other end of the drain pipe 82 is connected to the groove 71. The fixed box 8 is filled with gravel, which plays the role of supporting and fixing the position of the drain pipe 82.

[0046] The other end of the drain pipe 82 is connected to the collection box 81, so that the water that seeps into the guide plate 7 from the soil can flow along the groove 71 and be smoothly discharged into the collection box 81 through the drain pipe 82. The bottom of the collection box 81 is provided with a conduit 84 through the fixed box 8 to drain the water accumulated in the collection box 81 for subsequent treatment or discharge.

[0047] In practical use, this utility model involves coating the inner wall of the basement wall 1 with a moisture-proof coating 11. Moisture first seeps into the guide plate 7 from the soil side, then flows along the groove 71 and is discharged into the collection box 81 through the drain pipe 82 and out through the conduit 84. However, the seeping water may attempt to enter the waterproof and vapor-proof layer 4, but the water is blocked. A very small amount of water vapor passes through the vent 421 and is directed to the empty layer 5. The through hole 61 on the pipe 6 allows moisture to enter the interior of the pipe 6 from the empty layer 5 and is extracted and discharged to the outside through the negative pressure suction device 62. Then, the positive pressure air supply device is activated to send dry gas into the pipe 6. This gas enters the empty layer 5 through the through hole 61, further reducing humidity and maintaining the dry state of the wall 1. After the treatment is completed, the sealing cap 64 is snapped onto both ends of the pipe 6.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
