Description

Technical Field

[0001] This utility model relates to the field of basement drainage technology, specifically to a basement underground drainage water collection system. Background Technology

[0002] The basement bears the entire load of the building and transfers that load to the soil; its stability is crucial to the building's safety and lifespan. Traditional basement waterproofing focuses primarily on prevention. However, in practice, relying solely on waterproofing often fails to achieve the desired effect, frequently leading to leaks, water accumulation, and dampness due to damage to the waterproofing layer. These problems are difficult to resolve and costly to address later.

[0003] To address the aforementioned issues, Chinese Patent No. CN220469050U discloses a basement drainage structure, which includes an original subbase, a structural waterproofing board on the original subbase, a drainage layer on the structural waterproofing board, drainage ditches and impermeable concrete in the drainage layer, and a floor slab on the drainage layer.

[0004] Although this utility model can effectively drain water seepage from basements, its drainage layer is made of permeable concrete, which has limited drainage effect. Furthermore, it can only passively allow water to flow to the outside through underground channels, which is not conducive to automated water collection and drainage. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a basement underground drainage system, which solves the problems of limited drainage effect and inability to automatically collect and drain water in existing basement drainage structures.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A basement underground drainage system is provided, comprising a geotextile located below the floor level in the basement, a siphon drainage board laid below the geotextile, an underground ditch on the drainage side of the siphon drainage board, a permeable pipe installed in the underground ditch, the permeable pipe connected to a collection well, a submersible pump and a liquid level sensor installed in the collection well, both of which are electrically connected to a controller, and the outlet pipe of the submersible pump connected to the outside.

[0008] The working principle of this solution is as follows: the siphon drainage board drains water into the culvert, and the permeable pipes of the culvert drain the water into a collection well for collection. The controller uses a liquid level sensor to detect the hydraulic pressure and obtain the water level in the collection well. When the hydraulic pressure exceeds a set value, a submersible pump is activated to discharge the water from the collection well. The siphon drainage board utilizes the siphon principle to quickly and effectively drain accumulated water, and its drainage effect is better than that of permeable concrete. The collection well acts as a buffer, temporarily storing a certain amount of water to prevent excessive pressure on the culvert when it handles a large amount of water in a short period of time, thus improving the stability and efficiency of the system. Real-time monitoring of the liquid level by the liquid level sensor allows for timely detection and handling of abnormal situations, preventing seepage and water accumulation in the basement due to untimely drainage, and improving the safety of the basement.

[0009] Furthermore, the thickness of the geotextile is 10mm to 20mm.

[0010] Furthermore, the liquid level sensor is fixed on the side wall of the water collection well and close to the outlet of the permeable pipe.

[0011] Furthermore, a filter screen is installed at the inlet of the submersible pump. The filter screen prevents impurities from entering the submersible pump.

[0012] Furthermore, the controller is fixed inside the basement.

[0013] Furthermore, the controller is a PLC.

[0014] Furthermore, the controller is electrically connected to the alarm. If the level sensor detects a high level for an extended period, it indicates a malfunction in the submersible pump or excessive moisture. The alarm will then sound, alerting staff to inspect the pump and prevent water from overflowing from the collection well.

[0015] Furthermore, the porosity of the siphon drainage board is 70%–90%. Higher porosity improves drainage efficiency, ensuring that accumulated water is quickly discharged.

[0016] Furthermore, a water-resistant plate is installed at the bottom of the siphon drainage board.

[0017] Furthermore, the siphon drainage board is made of polyethylene or polypropylene. High-density polyethylene or polypropylene has good corrosion resistance and mechanical strength, making it suitable for use in underground environments.

[0018] This utility model discloses a basement underground drainage water collection system, the beneficial effects of which are:

[0019] This utility model's siphon drainage board utilizes the siphon principle to quickly and effectively drain accumulated water. Compared to permeable concrete, the siphon drainage board offers superior drainage. Furthermore, the use of a collection well and a level sensor enables water level control, improving the efficiency and safety of the drainage system, and ultimately enhancing the reliability and performance of the basement drainage system.

[0024] refer to Figure 1 and Figure 2 This embodiment provides a basement underground drainage system, including geotextile 2, siphon drainage board 3, underground ditch 4, water collection well 5, submersible pump 6 and liquid level sensor 7.

[0025] Geotextile 2 is located below the basement floor 1, and the thickness of geotextile 2 is 10mm to 20mm.

[0026] The siphon drainage board 3 is laid under the geotextile 2, and the bottom of the siphon drainage board 3 is provided with a water-resistant board 9.

[0027] In this embodiment, the siphon drainage board 3 is made of polyethylene or polypropylene. High-density polyethylene or polypropylene has good corrosion resistance and mechanical strength, making it suitable for underground environments. The porosity of the siphon drainage board 3 is 70%–90%. Higher porosity improves drainage efficiency, ensuring rapid drainage of accumulated water. The siphon drainage board 3 is lightweight, easy to transport and install, and utilizes the siphon principle to quickly and effectively drain accumulated water. Compared to permeable concrete, the siphon drainage board 3 offers better drainage performance.

[0028] The siphon drainage board 3 has a culvert 4 on its drainage side. A permeable pipe 41 is installed in the culvert 4. The permeable pipe 41 is connected to the water collection well 5. The water collection well 5 plays a buffer role and can temporarily store a certain amount of water to avoid excessive pressure when the culvert 4 processes a large amount of water in a short period of time, thereby improving the stability and efficiency of the system.

[0029] A submersible pump 6 and a level sensor 7 are installed inside the sump 5. The level sensor 7 is fixed on the side wall of the sump 5 and near the outlet of the permeable pipe 41. Both the submersible pump 6 and the level sensor 7 are electrically connected to the controller 8, and the outlet pipe of the submersible pump 6 is connected to the outside. By monitoring the water level in real time through the level sensor 7, abnormal situations can be detected and dealt with in a timely manner, preventing problems such as water seepage and water accumulation in the basement due to untimely drainage, and improving the safety of the basement.

[0030] As a further embodiment, a filter screen is provided at the inlet of the submersible pump 6. The filter screen prevents impurities from entering the submersible pump 6.

[0031] The controller 8 is fixed inside the basement and is electrically connected to the alarm 81. If the liquid level sensor 7 detects a high liquid level for an extended period, it indicates that the submersible pump 6 has malfunctioned or there is too much water. The alarm 81 will then sound an alarm to alert staff to inspect the area and prevent water from overflowing from the collection well 5. In this embodiment, the controller 8 is a PLC.

[0032] In summary, the working principle of this embodiment is as follows:

[0033] The working principle of this scheme is as follows: the siphon drainage board 3 drains water into the culvert 4, the permeable pipe 41 of the culvert 4 drains water into the collection well 5 for collection, and the controller 8 detects the water level of the collection well 5 through the liquid level sensor 7. When the hydraulic pressure is greater than the set value, the submersible pump 6 will be started to discharge the water in the collection well 5.

[0034] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
