[0022] Reference Figure 1 and Figure 6A drainage layer 26 is fixedly connected to the top side of the building base layer 1. The drainage layer 26 is composed of coarse sand. The coarse sand has good water permeability and can quickly drain water, reducing the potential damage of water accumulation to the building base. The gaps between the coarse sand particles allow water to flow while preventing the loss of soil and fine particles. A reinforcement layer 27 is fixedly connected to the top side of the drainage layer 26. On top of the drainage layer 26, the reinforcement layer 27 is further fixedly connected. The addition of this layer is intended to enhance the overall stability and bearing capacity of the foundation, especially in bearing large loads or preventing ground settlement. It plays a key role. The reinforcement layer 27 is composed of crushed stone. The reinforcement layer 27 is composed of crushed stone materials. These crushed stones not only provide good drainage channels, but also increase the stability of the structure due to their interlocking properties. The irregular shape of the crushed stones helps to lock adjacent stones. , preventing displacement, thereby improving the reinforcement effect. The inner walls of the left and right ends of the building base layer 1 are fixedly connected with a plurality of drainage components for accelerating drainage. A drainage pipe 31 is installed inside each drainage component, which is tightly combined with the inner wall of the component by a fixed connection. The function of the drainage pipe 31 is to provide a direct water flow channel to lead water out of the building base layer 1 to avoid adverse effects of water accumulation and water pressure on the structure. The inner wall of the drainage component is fixedly connected with a drainage pipe 31. The drainage component includes an outer layer 28, and the material of the outer layer 28 is gravel. The design of the drainage component is multi-layered, wherein the outer layer 28 is the outermost layer 28 of the system, directly in contact with the inner wall of the building base layer 1. The outer layer 28 is composed of gravel, which has sufficient strength to maintain the shape of the structure and sufficient water permeability to allow water to flow through; The outer parts of the plurality of outer layers 28 are respectively fixedly connected to the inner walls of the left and right ends of the building base layer 1, and the inner part of the outer layer 28 is further fixedly connected to the middle layer 29. In order to improve the functionality and efficiency of the drainage component, the middle layer 29 plays a role of transition and reinforcement. The inner wall of the outer layer 28 is fixedly connected to the middle layer 29. The material of the middle layer 29 is a drainage core. The inner wall of the middle layer 29 is fixedly connected to the inner layer 30. The middle layer 29 adopts the drainage core material. This material usually has good drainage performance and certain filtering function. The drainage core can effectively transport water from the outer layer 28 to the inner layer 30, while preventing mud and other fine particles from entering the drainage pipe 31. In order to protect the drainage pipe 31 and ensure the long-term operation of the drainage system, the inner wall of the middle layer 29 is fixedly connected to the inner layer 30, as the innermost layer 30 of the system, is in direct contact with the water flow. The material of the inner layer 30 is permeable geotextile. The inner layer 30 is composed of permeable geotextile, which can allow water to pass freely and prevent soil particles and impurities from entering the drainage pipe 31. The permeable geotextile has good durability and corrosion resistance and is suitable for long-term exposure to various water conditions. The inside of the inner layer 30 is fixedly connected to the outside of the drainage pipe 31, and the inner layer 30 is tightly attached to the outer wall of the drainage pipe 31 by a fixed connection, so that all water flows passing through the inner layer 30 can smoothly enter the drainage pipe 31, thereby effectively drawing water out of the building base layer 1. A plurality of openings 32 are provided inside the drainage pipe 31, and bolts 34 are threadedly connected at the far ends of the plurality of drainage pipes 31.

[0023] The present invention also discloses a method for decompressing drainage at the base of a building, comprising the following steps: Step 1: Open enough space in the building base layer 1 to accommodate the partition frame 2 and several drainage components on its sides; Step 2: fix the drainage assembly to the outer wall of the partition frame 2, and then backfill the building base layer 1; Step 3: construct and lay the drainage layer 26 and the reinforcement layer 27 on the upper part of the building base layer.

[0024] The drainage layer is a coarse sand layer and the reinforcement layer is a crushed stone layer.

[0025] Working principle: when the water level rises, water will flow into the interior of the partition frame 2 through the drainage assembly and the filter ring 4 between the partition circular plate 5 and the partition frame 2, and then as the water level rises, it will flow into the enclosed space formed by the opening of the cavity 20 of the partition frame 2, and then it will be stored and rise in this enclosed space, and then after it is higher than the positioning ring 22, the buoyancy ball 23 will float upward by using the water and its own buoyancy, thereby being able to push the vertical rod 24 to slide upward, and then drive the warning column 25 to slide upward. As the water level continues to rise, the warning column 25 will also slowly rise and be seen by the staff. At this time, the staff will drive the water pump 8 to pump out the water inside the partition frame 2 in the same way as above. The warning structure is simple in composition, low in cost, and easy to assemble, thereby reducing initial investment and later maintenance; When water enters the partition frame 2 through the filter ring 4, the soil and gravel in the building base layer 1 are filtered out by the filter ring 4, thereby preventing the soil and gravel from blocking the water pump 8, the water inlet pipe 9 and the water outlet pipe 10, thereby improving the pumping efficiency; at the same time, after driving the water pump 8, the water pump 8 will use the water inlet pipe 9 to pump out the water inside the partition frame 2. After the water flow passes through the multiple rotating blades 15, the multiple rotating blades 15 are restricted by the connecting column 14, so that the rotating blades 15 can rotate at this time, and then drive the rotating shaft 13 to rotate, thereby driving the connecting column 16 to rotate, and driving the rotating plate 17 to rotate through the connecting column 16, and then driving the side block 18 to rotate, thereby driving the brush 19 to rotate and clean the filter ring 4, preventing the soil and gravel from blocking the filter ring 4, while avoiding the blockage caused by soil and gravel, it can further improve the pumping efficiency; The building base layer 1 is composed of coarse sand and a drainage layer 26. The good water permeability of the coarse sand is used to quickly drain water, and the gaps between the particles prevent the loss of soil and fine particles. A reinforcement layer 27 composed of crushed stone material is further placed on the drainage layer 26, which not only provides a drainage channel, but also increases the structural stability due to its interlocking nature. In addition, the drainage components inside the building base layer 1, each drainage component is installed with a drainage pipe 31 inside, which is tightly combined by welding to directly provide a water flow channel to draw out water. The drainage component is designed as a multi-layer structure, and the outer layer 28 is made of gravel material to maintain the structural shape while allowing water to flow through; The middle layer 29 uses drainage core material to play a transition and reinforcement role, effectively transporting water and preventing impurities from entering the drainage pipe 31; the inner layer 30 uses permeable geotextile material, which allows water to pass freely while preventing soil particles from entering, protecting the drainage pipe 31. The opening 32 inside the drainage pipe 31 and the bolt 34 at the far end ensure the sealing and efficiency of the system. Overall, the structure achieves effective drainage and removal of moisture inside the building base through the coordinated work of the coarse sand drainage layer 26, the crushed stone reinforcement layer 27 and the multi-layer designed drainage components, thereby reducing the potential damage of accumulated water to the building base and enhancing the overall stability and bearing capacity of the foundation.
