[0022] like Figures 1 to 3 As shown, the utility model preferably provides a basement roof siphon drainage system, which includes a basement roof 1, a paving plate 2 arranged above the basement roof 1, and a siphon component 3 arranged below the basement roof 1. The paving plate 2 includes a covering layer 21 for planting plants, an isolation layer 22 for isolating foreign matter, a drainage layer 23 for collecting accumulated water, and a waterproof layer 24 for isolating accumulated water, which are arranged in sequence from the ground to the basement roof 1; the drainage layer 23 includes a drainage board 26 and a drainage pipe 27, the drainage board 26 is respectively arranged at both ends of the drainage pipe 27, and a plurality of protrusions 261 are provided on one end surface of the drainage board 26 close to the waterproof layer 24, and a plurality of protrusions 261 are formed between the waterproof layer 24 and the plurality of protrusions 261. There is a circulation channel, and first openings 271 are provided at both ends of the bottom of the drain pipe 27, and the circulation channel is connected to the first opening 271, and a second opening 272 is provided at the bottom end of the drain pipe 27; the siphon assembly 3 includes an inlet pipe 31 and an outlet pipe 33 extending in the vertical direction and a siphon pipe 32 extending in the horizontal direction, the inlet pipe 31 is arranged below the basement roof 1, one end of the inlet pipe 31 passes through the basement roof 1 and is connected to the second opening 272 of the drain pipe 27, the siphon pipe 32 is arranged below the inlet pipe 31, and the other end of the inlet pipe 31 is connected to the siphon pipe 32, the outlet pipe 33 is arranged below the siphon pipe 32, and the end of the siphon pipe 32 facing away from the inlet pipe 31 is connected to the outlet pipe 33.

[0023] Based on the above technical features, the utility model is provided with a paving plate 2, which is responsible for collecting the accumulated water on the basement roof 1 and discharging it into the siphon assembly 3. The paving plate 2 includes a covering layer 21, an isolation layer 22, a drainage layer 23 and a waterproof layer 24, wherein the drainage layer 23 includes a drainage board 26 and a drainage pipe 27. The drainage board 26 is provided at both ends of the drainage pipe 27, and a plurality of protrusions 261 are provided on one end face thereof close to the waterproof layer 24. A flow channel is formed between these protrusions 261, which helps the accumulated water to flow quickly to the drainage pipe 27. The drainage pipe 27 has a first opening 271 and a second opening 272. The first opening 271 is connected to the flow channel of the drainage board 26 to receive the accumulated water, and the second opening 272 is connected to the water inlet pipe 3 1 is connected to guide the accumulated water into the siphon component 3; through the setting of the siphon component 3, the siphon component 3 is located below the basement roof 1, and uses the siphon principle to accelerate the drainage process. The siphon component 3 includes an inlet pipe 31, a siphon pipe 32 and an outlet pipe 33. The inlet pipe 31 extends in a vertical direction, one end of which is connected to the second opening 272 of the drain pipe 27 to receive the accumulated water from the drainage layer 23, and the other end is connected to the siphon pipe 32 to guide the accumulated water into the siphon pipe 32. The siphon pipe 32 extends in a horizontal direction and is located below the inlet pipe 31. When the water flow in the inlet pipe 31 reaches a certain level, the diameter of the outlet pipe 33 is smaller than the diameter of the siphon pipe 32, so that negative pressure is generated in the siphon pipe 32, forming a siphon phenomenon and accelerating drainage.

[0024] As some embodiments of the present invention, Figure 1 As shown, there are multiple drainage pipes 27, each spaced apart along the length of the basement roof 1. This arrangement ensures that accumulated water on the roof 1 is quickly dispersed into each of the drainage pipes 27, thereby accelerating drainage and reducing the duration of accumulated water. This layout helps avoid drainage problems or flooding caused by excessive localized water accumulation, thereby improving overall drainage efficiency.

[0025] As some embodiments of the present invention, Figure 1 As shown, there are multiple water inlet pipes 31, and each water inlet pipe 31 corresponds to the drainage pipe 27. One end of each water inlet pipe 31 is connected to the second opening 272, and the other end is connected to the siphon pipe 32. The one-to-one correspondence between the water inlet pipe 31 and the drainage pipe 27 ensures that the accumulated water in each area of ​​the drainage layer 23 can be effectively guided into the siphon assembly 3, avoiding confusion and crossover of the water flow during the drainage process. This design helps achieve more efficient drainage, reduces the retention time of accumulated water, and improves drainage efficiency.

[0026] As some embodiments of the present invention, Figure 1As shown, siphon assembly 3 also includes a reservoir 34, which is disposed below outlet pipe 33. One end of reservoir 34 is connected to outlet pipe 33, and the other end is connected to the municipal drainage system. Reservoir 34, located below outlet pipe 33, serves as a buffer zone, receiving and storing water discharged from outlet pipe 33. This helps balance drainage flow and avoid excessive pressure on the municipal drainage system during peak hours.

[0027] As some embodiments of the present invention, Figure 2 As shown, the drain pipe 27 further includes a third opening 273, which is provided at both ends of the drain pipe 27. There are multiple third openings 273, which are spaced apart along the length of the drain pipe 27. The provision of multiple third openings 273 can more effectively collect and discharge water, especially in areas with heavy rainfall or high drainage needs. By dispersing the drainage points, the drainage pressure of the first opening 271 can be reduced. At the same time, multiple drain pipes 27 are horizontally connected through the third openings 273 to form a drainage system, thereby improving the overall drainage efficiency of the system.

[0028] As some embodiments of the present invention, Figure 2 As shown, the drain pipe 27 further includes a fourth opening 274, which is respectively provided at the front and rear ends of the drain pipe 27. By providing the fourth opening 274, the front and rear ends of each drain pipe 27 can be connected to other drain pipes 27, and the length of the drain pipe 27 can be adjusted according to actual conditions, further ensuring the applicability of the drain pipe 27.

[0029] In some embodiments of the present invention, the height of the circulation channel is not less than 50 mm, and an air isolation area is formed in the circulation channel to prevent plant roots from growing along the direction of the waterproof layer 24. The drainage board 26 is provided with a raised portion 261, so that after the drainage board 26 is covered with soil, air exists in its circulation channel. The existing air is used to block the growth of plant roots. The air isolation area formed in the circulation channel makes it difficult for plant roots to continue to grow downward in the absence of water and nutrients, effectively preventing the plant roots from affecting the basement roof 1.

[0030] As some embodiments of the present invention, Figure 1As shown, the paving panels 2 also include a leveling layer 25. The bottom end of the leveling layer 25 is laid on the basement roof 1, and the top end of the leveling layer 25 is connected to the waterproof layer 24 to improve the flatness of the paving panels 2. The main function of the leveling layer 25 is to provide a flat surface on which the drainage layer 23 and the waterproof layer 24 can be laid evenly and stably. By adjusting the leveling layer 25, the unevenness and defects on the basement roof 1 can be eliminated, ensuring the installation quality of the paving panels 2, and ensuring that the foundation of the drainage board 26 is always in a stable state, effectively improving the drainage efficiency of the drainage board 26.

[0031] The working process of the present utility model is as follows: when rainwater or accumulated water accumulates on the basement roof 1, they penetrate into the drainage layer 23 through the covering layer 21; the accumulated water in the drainage layer 23 flows in the circulation channel on the drainage board 26 and merges into the drainage pipe 27; the drainage pipe 27 guides the accumulated water into the water inlet pipe 31. When the water flow in the water inlet pipe 31 increases to a certain level, a siphon phenomenon occurs in the siphon pipe 32, accelerating the drainage process; the accumulated water is finally discharged to the water reservoir 34 through the outlet pipe 33, and enters the municipal government drainage system through the water reservoir 34, completing the drainage process.

[0032] In summary, the embodiment of the present invention provides a basement roof siphon drainage system, which has the following beneficial effects compared with the prior art: 1) paving panels 2, which are responsible for collecting the accumulated water on the basement roof 1 and discharging it into the siphon assembly 3. The paving panels 2 include a covering layer 21, an isolation layer 22, a drainage layer 23 and a waterproof layer 24, wherein the drainage layer 23 includes a drainage board 26 and a drainage pipe 27. The drainage board 26 is arranged at both ends of the drainage pipe 27, and a plurality of protrusions 261 are provided on one end face close to the waterproof layer 24. A flow channel is formed between these protrusions 261, which helps the accumulated water to flow quickly to the drainage pipe 27. The drainage pipe 27 has a first opening 271 and a second opening 272. The first opening 271 is connected to the flow channel of the drainage board 26 to receive the accumulated water, and the second opening 272 is connected to the flow channel of the drainage board 26 to receive the accumulated water. The second opening 272 is connected to the water inlet pipe 31 and is used to guide the accumulated water into the siphon assembly 3; 2) the siphon assembly 3, which is located below the basement roof 1 and uses the siphon principle to accelerate the drainage process. The siphon assembly 3 includes an inlet pipe 31, a siphon pipe 32 and an outlet pipe 33. The inlet pipe 31 extends in a vertical direction, one end of which passes through the basement roof 1 and is connected to the second opening 272 of the drain pipe 27 to receive the accumulated water from the drainage layer 23, and the other end is connected to the siphon pipe 32 to guide the accumulated water into the siphon pipe 32. The siphon pipe 32 extends in a horizontal direction and is located below the inlet pipe 31. When the water flow in the inlet pipe 31 reaches a certain level, and the diameter of the outlet pipe 33 is smaller than that of the siphon pipe 32, a negative pressure is generated in the siphon pipe 32, forming a siphon phenomenon and accelerating drainage. The utility model effectively solves the problems of low drainage efficiency and easy leakage of accumulated water in the basement roof drainage system in the prior art.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
