Description

Technical Field

[0001] The utility model relates to the technical field of drainage systems, in particular to a siphon drainage structure for a basement top plate. Background Art

[0002] Siphon drainage uses the atmospheric pressure difference between the surface and underground space to change the pressure state of water flow in the pipe through the variable diameter design of the system structure. When the air in the pipe is squeezed by rainwater to form a vacuum full pipe flow, the pressure difference between the inlet and outlet of the pipe is the largest, and a siphon effect will be generated, which will accelerate the suction and collection of rainwater. Specific formation process: surface rainwater infiltrates into the drainage system. When the rainfall is small, the infiltrated rainwater is naturally discharged due to gravity. With continuous rainfall, the water collection in the system increases, and the air in the siphon pipe is quickly squeezed out by rainwater, and a vacuum is generated in the drainage pipe to form a negative pressure. The water in the pipe is in a state of full pipe flow under pressure, forming a siphon phenomenon, and continuous drainage. In the process of continuous rainfall drainage, due to the continuous siphon effect, the entire system can quickly discharge the infiltrated rainwater. The pipes of the siphon drainage system are designed according to the full flow and pressure state, and the drainage blind pipe can be laid without slope, breaking the conventional gravity drainage system. When the siphon effect occurs, the water flow rate is accelerated and has a good self-cleaning effect.

[0003] The siphon drainage system in the prior art is mainly composed of a drainage trough, a drainage shaped sheet, a geotextile, a siphon pipe, etc. The water received by the drainage shaped sheet flows into the drainage trough, and the siphon pipe is used to form a siphon effect to drain the water.

[0004] However, the siphon drainage system in the prior art directly discharges rainwater without forming an ecosystem for water resource utilization. Directly discharged rainwater will also cause a waste of water resources and cannot be better utilized. In order to improve this situation, it is necessary to design a basement roof siphon drainage structure. Utility Model Content

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] See also Figure 1-3 , a basement top plate siphon drainage structure, comprising:

[0033] Drainage ditch 1 and drainage shaped sheet 2, the drainage ditch 1 and the drainage shaped sheet 2 are laid on the same plane, the drainage ditch 1 is a plurality of the same structure and is evenly cross-distributed in a grid shape, the drainage ditch 1 and the drainage shaped sheet 2 are connected to each other, the upper surface of the drainage ditch 1 and the drainage shaped sheet 2 is laid with geotextile 3, the top of the geotextile 3 is backfill soil, the accumulated water on the backfill soil flows into the drainage shaped sheet 2 through the geotextile 3, and flows into the drainage ditch 1 along the drainage shaped sheet 21 to be drained;

[0034] A plurality of water inlets 4 connected to the drainage shaped sheets 2 are arranged on both sides of the drainage trough 1, so that the accumulated water on the drainage shaped sheets 2 can flow into the drainage trough 1 through the water inlets 4;

[0035] The bottom of the drainage trough 1 is connected with a siphon pipe 5 extending laterally, so that the siphon pipe 5 cooperates with the drainage trough 1 and the drainage special-shaped sheet 2 to form a siphon drainage structure;

[0036] A water storage tank 6 is pre-buried under the drainage shaped sheet 2. The top of the water storage tank 6 is connected to a first water diversion pipe 7 and a first drainage pipe 8 extending upward to the ground. The upper end of the first water diversion pipe 7 is connected to an anti-blocking water inlet head structure, so that when the rain is heavy and water accumulates, the anti-blocking water inlet head structure can enter the first water diversion pipe 7 to be poured into the water storage tank 6 for storage. The anti-blocking water inlet head structure collects rainwater and also has an anti-blocking effect. The upper end of the first drainage pipe 8 is provided with an irrigation mechanism for irrigating vegetation on the ground. The water stored in the water storage tank 6 is used when there is no rain or when there is a lack of water on the surface, so as to achieve the purpose of recycling the collected rainwater. A second drainage pipe 9 is set at the lower end of the water storage tank 6, and the second drainage pipe 9 is connected to the siphon pipe 5, so that when the water storage tank 6 is full of rainwater on rainy days, the second drainage pipe 9 is started to drain the water. Under the premise of ensuring the liquid level in the water storage tank 6, it also plays an auxiliary drainage effect. Therefore, a liquid level sensor can be set in the water storage tank 6, and the controller can be used to control the opening and closing of the second drainage pipe 9.

[0037] Furthermore, an observation well 10 is set at the end of the siphon pipe 5, and a discharge pipe 11 is set at the lower end of the observation well 10. The observation well 10 is conducive to observing the drainage situation and is convenient for maintenance. Finally, the drainage flows from the siphon pipe 5 into the observation well 10 and is finally discharged through the discharge pipe 11.

[0038] Furthermore, the anti-blocking water inlet head structure includes:

[0039] A cylindrical cavity shell 12, which is arranged on the top of the first water diversion pipe 7 and communicated with the first water diversion pipe 7, and a plurality of water inlets 13 are circumferentially provided on the side of the cylindrical cavity shell 12;

[0041] The annular mesh baffle plate 15 is disposed outside the cylindrical cavity shell 12 in an annular manner. The annular mesh baffle plate 15 is connected between the arc surface cover plate 14 and the cylindrical cavity shell 12 .

[0042] Specifically, the curved cover plate 14 cooperates with the annular mesh baffle plate 15 to allow rainwater to enter from the annular mesh baffle plate 15 and enter the cylindrical cavity shell 12 through the water inlet 13 and flow into the first water diversion pipe 7. In this process, the annular mesh baffle plate 15 blocks the soil to prevent the soil from entering the cylindrical cavity shell 12, and the curved cover plate 14 prevents water accumulation on the top.

[0043] Further, irrigation institutions include;

[0044] A transverse pipe 16, which is disposed at the upper end of the first drainage pipe 8 and communicated with the first drainage pipe 8;

[0045] A water pump 17, which is arranged on the transverse pipe 16 to pump out the water stored in the water tank 6 for irrigation; and

[0046] The nozzles 18 are multiple nozzles 18 arranged on the transverse pipes 16 for spraying water.

[0047] The water stored in the water storage tank 6 is pumped out by a water pump 17 to enter the transverse pipe 16 through the first drainage pipe 8 and is sprayed out through the sprinkler 18 to achieve irrigation.

[0048] Furthermore, a solenoid valve 19 is provided on the second drainage pipe 9, so that the solenoid valve 19 can be opened according to the amount of water stored in the water tank 6 when the water is full, and the second drainage pipe 9 can discharge the water stored in the water tank 6 to achieve the effect of auxiliary drainage. Therefore, a liquid level sensor can be provided in the water tank 6 to cooperate with the controller to control the opening and closing of the second drainage pipe 9. Among them, all electrical components involved in the device and their electrical connection and use control are common knowledge known to technical personnel in the field, and will not be repeated here.

[0049] Furthermore, the upper end of the side surface of the drainage trough 1 is connected to a second water diversion pipe 20, which extends upward to above the ground. An anti-blocking water inlet head structure is arranged at the upper end of the second water diversion pipe 20. Rainwater entering through the anti-blocking water inlet head structure also enters the drainage trough 1 through the second water diversion pipe 20 to be directly discharged through the drainage trough 1.

[0050] To sum up, while the device utilizes the siphon drainage structure to effectively drain water at the top plate of the basement, it also collects and stores rainwater through the first water diversion pipe on the water storage tank in conjunction with the anti-blocking water inlet head structure for irrigation of vegetation on the ground, thereby achieving the effect of rainwater recycling and reuse. At the same time, after the water storage tank is full of water, the surplus can be discharged through the second drainage pipe, which plays a role in assisting the siphon drainage device to drain water, so as to better drain the top plate of the basement.

[0051] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
