Description

Technical Field

[0001] This utility model relates to the field of underground moisture-proof structure technology, and in particular to a water-absorbing underground moisture-proof structure. Background Technology

[0002] Basements, being rooms below the ground level, are constantly exposed to the influence of the backfill layer and the high moisture content of the surrounding soil. If the original waterproofing layer on the exterior of the main building structure is improperly constructed, poorly done, or damaged further during subsequent construction, groundwater can easily seep into the basement. This not only leads to dampness and condensation in the basement, affecting its functionality and comfort, but may also threaten the safety of the main structure.

[0003] To address the issue of basement dampness, various damp-proofing technologies have been developed, among which absorbent underground damp-proof structures are an effective solution. These structures, through specific design, can absorb and drain moisture from the soil surrounding the basement, thus keeping the basement dry.

[0004] In cases where moisture-proof structures have limited moisture-proofing effects and poor drainage, problems such as dampness and mold growth on basement walls and floors may occur. Therefore, a water-absorbing underground moisture-proof structure is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a water-absorbing underground moisture-proof structure to solve the problems of dampness and mold growth on basement walls and floors caused by the limited moisture-proof effect and poor drainage of the moisture-proof structures proposed in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a water-absorbing underground moisture-proof structure is provided, including a wall, wherein a moisture-proof layer for preventing dampness in the basement space is provided on the outer side of the wall, the moisture-proof layer includes at least a water-absorbing layer for absorbing moisture from the underground soil, a drainage board for collecting moisture in the water-absorbing layer is fixedly provided at the bottom of the moisture-proof layer, and two sets of inclined drainage slopes are fixedly provided below the drainage board.

[0007] Furthermore, the wall is made of breathable bricks, and a suspended layer is fixedly installed on the outside of the wall to provide air circulation space, and the moisture-proof layer is located on the other side of the suspended layer.

[0008] Furthermore, a waterproof membrane is fixedly provided on one side of the absorbent layer, and a breathable layer is fixedly provided on the other side of the absorbent layer, and the breathable layer is fixedly connected to the overhead layer.

[0009] Furthermore, the waterproof membrane has a number of inclined filter holes arranged in a rectangular array, and the diameter of the filter holes gradually increases from one end to the water-absorbing layer end.

[0010] Furthermore, the waterproof membrane is a waterproof material, the absorbent layer is a superabsorbent polymer, and the breathable layer is a microporous breathable membrane.

[0011] Furthermore, two symmetrical horizontal pipes are fixedly installed inside the drainage plate. Several water inlet pipes are fixedly installed above each horizontal pipe, and several water outlet pipes are fixedly installed below each horizontal pipe. The horizontal pipes are connected to the water inlet pipes and the water outlet pipes.

[0012] Furthermore, the diameter of the horizontal pipe is larger than the diameter of the inlet pipe, and the diameter of the inlet pipe is larger than the diameter of the outlet pipe.

[0013] Furthermore, the inlet pipe and outlet pipe are arranged alternately in the horizontal direction, and a spherical protrusion is provided at the center of the inlet pipe.

[0014] Furthermore, the drainage slope is provided with several inclined channels, and the channels are connected to the outlet pipes.

[0015] Furthermore, several conduits are fixedly installed at the bottom of the drainage slope, with one end of each conduit connected to a flow channel and the other end of each conduit fixedly installed with a water tank.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this water-absorbing underground moisture-proof structure, a moisture-proof layer is set up. The water-absorbing layer can quickly absorb moisture from the underground soil and water vapor that seeps in from the external environment, effectively preventing water vapor from accumulating inside the moisture-proof layer. The waterproof membrane on one side can effectively prevent water from directly penetrating into the interior of the moisture-proof layer from the external environment. Although a small amount of water or water vapor may seep in after long-term use, the design of the filter holes allows water to flow smoothly to the water-absorbing layer instead of accumulating on the surface of the waterproof membrane. The breathable layer on the other side can effectively prevent water from seeping from the interior of the moisture-proof layer to the wall side while ensuring air circulation.

[0018] 2. In this water-absorbing underground moisture-proof structure, a drainage board is installed. The presence of spherical protrusions on the water inlet pipe increases the contact area between water and the inner wall of the water inlet pipe, so that more water can be effectively captured and guided into the pipe, and also prevents water accumulation and blockage.

[0031] 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.

[0032] Please see Figures 1-7 As shown, the purpose of this embodiment is to provide a water-absorbing underground moisture-proof structure, including a wall 1. A moisture-proof layer 3 for preventing moisture in the basement space is provided on the outside of the wall 1. The moisture-proof layer 3 includes at least a water-absorbing layer 32 for absorbing moisture from the underground soil. A drainage board 4 for collecting moisture from the water-absorbing layer 32 is fixedly provided at the bottom of the moisture-proof layer 3. Two sets of inclined drainage slopes 5 are fixedly provided below the drainage board 4.

[0033] Wall 1 is constructed of breathable bricks with a porous structure, effectively capturing and storing moisture from both inside and outside the basement. When indoor humidity is high, the breathable bricks absorb excess moisture and slowly release it into the external environment through their internal pore structure, thus maintaining indoor humidity balance and preventing dampness on the basement walls and floor. A raised floor 2 is fixedly installed on the outside of wall 1, providing air circulation space. The raised floor 2 isolates wall 1 from the external environment while allowing air to flow freely within it. This not only accelerates the removal of moisture from inside wall 1 but also reduces the impact of the external environment on the basement's internal humidity to some extent. A moisture-proof layer 3 is located on the other side of the raised floor 2.

[0034] A waterproof membrane 31 is fixedly installed on one side of the absorbent layer 32, and a breathable layer 33 is fixedly installed on the other side of the absorbent layer 32, and the breathable layer 33 is fixedly connected to the overhead layer 2.

[0035] The waterproof membrane 31 has a number of inclined filter holes 311 arranged in a rectangular array inside, and the diameter of the filter holes 311 gradually increases from one end to the water-absorbing layer 32. This allows water to be subjected to a gradually increasing gravitational force when it flows through the filter holes 311, thus flowing more smoothly to the water-absorbing layer 32.

[0036] The waterproof membrane 31 is a waterproof material, preferably a PE (polyethylene) film, which can effectively prevent water penetration and avoid moisture accumulation inside the moisture barrier 3. However, after prolonged use, a small amount of water penetration or water vapor circulation may occur. The absorbent layer 32 is a superabsorbent polymer (such as sodium polyacrylate, polyacrylamide, etc.). When water or water vapor molecules come into contact with the surface of the absorbent layer 32, they will gradually penetrate into the resin and be adsorbed. The water vapor will be effectively converted into liquid water, and the moisture will be adsorbed inside the absorbent layer 32 and will not diffuse into the basement. The breathable layer 33 is a microporous breathable membrane (such as PTFE or EVA), which can achieve good breathability while ensuring waterproof performance. The breathable layer 33 not only helps to regulate the air circulation and humidity balance inside the moisture barrier 3, but also effectively prevents moisture from penetrating to the wall 1 side.

[0037] Two symmetrical horizontal pipes 41 are fixedly installed inside the drainage board 4. Several inlet pipes 42 are fixedly installed above each horizontal pipe 41, and several outlet pipes 43 are fixedly installed below each horizontal pipe 41. The horizontal pipes 41 are connected to the inlet pipes 42 and the outlet pipes 43. One end of the inlet pipe 42 extends into the interior of the absorbent layer 32. Because water in the absorbent layer 32 gradually flows downwards under gravity, the inlet pipe 42 can capture and guide this flowing water into the horizontal pipes 41, and then discharge it through the outlet pipes 43.

[0038] The diameter of the horizontal pipe 41 is larger than the diameter of the inlet pipe 42, the diameter of the inlet pipe 42 is larger than the diameter of the outlet pipe 43, and the number of outlet pipes 43 exceeds the number of inlet pipes 42, which helps to quickly collect and transport large amounts of water.

[0039] The water inlet pipe 42 and the water outlet pipe 43 are arranged in a staggered manner in the horizontal direction to ensure that the water is evenly distributed inside the drainage plate 4 and avoid local water accumulation. In addition, the water inlet pipe 42 has a spherical protrusion at its center, which increases the contact area between the water and the inner wall of the water inlet pipe 42, so that more water can be effectively captured and guided into the pipe. Furthermore, the spherical protrusion also plays a role in dispersing water, preventing water accumulation and blockage, which not only improves drainage efficiency but also extends the service life of the drainage plate 4.

[0040] Several inclined channels 51 are formed within the drainage slope 5. This inclined design ensures that water flows smoothly along the channels 51 under gravity, accelerating the drainage speed. Each channel 51 is connected to a corresponding outlet pipe 43, meaning that one end of each channel 51 is connected to an outlet pipe 43, ensuring that water flows directly from the outlet pipe 43 into the channel 51 and is smoothly discharged. This not only improves drainage efficiency but also prevents water from stagnating and accumulating inside the drainage plate 4.

[0041] Several conduits 6 are fixedly installed at the bottom of the drainage slope 5. One end of each conduit 6 is connected to a flow channel 51, and the other end of each conduit 6 is fixedly connected to a water tank 7. The addition of the conduits 6 and the water tank 7 makes the drainage system more complete and efficient. The flow channel 51 in the drainage slope 5 can quickly capture and discharge water, while the conduits 6 ensure that this water flows smoothly into the water tank 7, which stores and treats the water. This not only improves drainage efficiency but also achieves sustainable water resource utilization and environmentally friendly development. The moisture barrier 3 absorbs and collects water, thus providing moisture protection for the basement.

[0042] In practical use, when the external humidity of the basement is high or there is moisture in the soil, a small amount of water or water vapor in the waterproof membrane 31 will come into contact with the absorbent layer 32 through the filter holes 311 after long-term use. The water will then be absorbed and flow downwards into the inlet pipe 42 under the action of gravity. The inlet pipe 42 will guide the water in the absorbent layer 32 into the horizontal pipe 41. The horizontal pipe 41 will then distribute the water evenly to each outlet pipe 43 and then discharge it into the flow channel 51 of the drainage slope 5. The water will enter the conduit 6 through the flow channel 51 and will eventually be guided into the water tank 7 for storage or treatment. During this process, the breathable layer 33 effectively prevents water from seeping from the inside of the moisture-proof layer 3 to the wall 1 side, and the suspended layer 2 further blocks water from entering the basement.

[0043] 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.
