Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction drainage, in particular to a drainage device for groundwater. Background Art
[0002] In modern urban construction, basements, as an essential component of architecture, are widely used in residential, commercial, and public facilities settings. However, with the acceleration of urbanization and the continuous development and utilization of underground space, the issue of basement floor waterproofing has become increasingly prominent, especially in southern China, where groundwater levels are relatively high.
[0003] Traditional basement slab waterproofing primarily relies on the use of materials such as waterproofing membranes and coatings, as well as self-waterproofing methods. However, these measures often face numerous limitations in practical application. First, the varying quality of waterproofing materials, improper construction practices, and inadequate subsequent maintenance can all lead to waterproofing failure, potentially causing seepage and leakage in the basement slab. Second, the dynamic fluctuations in the groundwater level make traditional waterproofing measures difficult to adapt, especially during the rainy season, when rising groundwater levels increase the pressure on the waterproofing layer, making it more susceptible to damage and leakage.
[0004] Water seepage and leakage from basement slabs not only affect the normal use of a building but can also damage the structure, shortening its lifespan. Long-term water accumulation can also lead to damp conditions within the basement, fostering mold growth and impacting the health of residents. Furthermore, water seepage and leakage increase building maintenance costs, resulting in financial losses for users.
[0005] To address these issues, the industry has explored various solutions, such as increasing the thickness of waterproofing layers, employing high-performance waterproofing materials, and strengthening construction supervision. However, these measures often only address the symptoms, failing to fundamentally resolve the problem of water seepage and leakage in basement slabs. Traditional waterproofing measures are particularly ineffective in areas with high groundwater levels. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense.

[0032] See also Figures 1 to 2 As shown, the utility model is a drainage device for groundwater, comprising a foundation soil layer 20 arranged on the basement floor, a concrete layer 10 laid on the upper part of the foundation soil layer 20, a sump 40 for storing accumulated water provided on one side of the concrete layer 10, and a drainage mechanism 50 for guiding the accumulated water into the sump 40 provided in the foundation soil layer 20 and the concrete layer 10; the drainage mechanism 50 comprises:
[0033] The drainage tube 51 has mesh-shaped through holes 53 on its side wall and / or bottom wall. The mesh-shaped through holes 53 have a diameter of 5mm-8mm and a hole spacing of 10mm-15mm, and are distributed in a staggered arrangement.
[0034] A reducer 54 is welded to the upper end of the drainage tube 51;
[0035] The drainage elbow 55 is fixedly connected to the reducer 54 via a clamp;
[0036] One end of the drainage pipe 56 is connected to the drainage elbow 55 , and the other end extends into the sump 40 .
[0037] In an optional embodiment, the outer periphery of the drainage tube 51 is covered with a filter sleeve 52 for filtering sand and gravel.
[0038] It should be noted that the provision of the filter sleeve 52 can effectively prevent sand and gravel from entering the drainage tube 51, thereby causing the drainage mechanism 50 to be blocked and resulting in failure to drain water normally.
[0039] In an optional embodiment, a sand and gravel filter layer 30 is provided outside the filter sleeve 52 .
[0040] It should be noted that the sand and gravel filter layer 30 is composed of gravel with a particle size of 10mm-20mm and a thickness of not less than 200mm, which can effectively enhance the water filtering capacity and disperse the groundwater pressure to avoid local seepage damage.
[0041] In an optional embodiment, a check valve 57 is provided at the end of the drain pipe 56 .
[0042] It should be noted that the check valve 57 is provided to prevent the water in the sump 40 from flowing back, thereby ensuring one-way drainage.
[0043] In an optional embodiment, the filter sleeve 52 is made of cotton and linen cloth, the porosity of the cotton and linen cloth is 60%-80%, and the side of the cotton and linen cloth away from the drainage tube 51 is coated with a waterproof resin coating.
[0044] It should be noted that the provision of the waterproof resin coating ensures that the cotton and linen cloth is prevented from rotting due to long-term immersion while filtering out impurities, thereby increasing the service life of the drainage device.
[0045] In an optional embodiment, the drainage pipe 56 is arranged along the slope of the basement concrete layer 10, and the slope ranges from 1% to 3%.
[0046] It should be noted that the drainage pipe 56 is set at an angle to utilize the principle of gravity flow to enhance drainage efficiency.
[0047] In an optional embodiment, a sewage discharge mechanism 60 for discharging sand and soil in the drainage tube 51 is provided on the drainage bend 55, and a sewage trough 101 for removing sand and soil is provided at the upper end of the concrete layer 10. A slot cover plate 102 is rotatably installed at the upper end of the sewage trough 101, and the size of the slot cover plate 102 is larger than the diameter of the sewage trough 101.
[0048] It should be noted that the spiral sewage discharge mechanism can manually remove accumulated sand, and the sewage trough 101 and the slot cover 102 are easy to clean, which extends the life of the device. The large size of the slot cover 102 ensures that it remains stable when covered, and the slot of the sewage trough 101 is used to support the slot cover 102.
[0049] In an optional embodiment, the sewage discharge mechanism 60 includes a sewage discharge pipe 61 connected to the side wall of the drainage bend 55, and an upper sealing plate 62 is fixedly provided on the upper end of the sewage discharge pipe 61. The sewage discharge pipe 61 is located on the side wall of the sewage trough 101 and is provided with a sewage discharge outlet. A sewage discharge side cover 63 is rotatably installed at the sewage discharge outlet, and the lowest point of the sewage discharge outlet is higher than the highest point of the drain pipe 56. A spiral sewage discharge assembly is rotatably installed in the sewage discharge pipe 61.
[0050] It should be noted that the spiral sewage discharge assembly can pull the sand and gravel in the drainage tube 51 upward and discharge it to prevent the sand and gravel from clogging the drainage tube 51, and the height of the sewage outlet is higher than the height of the drain pipe 56, ensuring that the accumulated water will not overflow from the sewage pipe 61 during normal drainage.
[0051] In an optional embodiment, the spiral sewage discharge assembly includes a sewage discharge shaft 65 that rotates and passes through the upper sealing plate 62, and a sewage discharge knob 64 is fixedly installed on the upper end of the sewage discharge shaft 65. The sewage discharge shaft 65 is located in the sewage pipe 61. The outer periphery is provided with a sewage discharge spiral piece 66, and the sewage discharge shaft 65 is located in the drainage tube 51. The outer periphery is provided with a lifting spiral piece 67, and the outer periphery of the sewage discharge shaft 65 located in the reducing joint 54 is provided with a reducing spiral piece 68. The outer diameter of the reducing spiral piece 68 gradually decreases from bottom to top, and the upper part of the reducing spiral piece 68 is smoothly connected to the sewage discharge spiral piece 66, and the lower part of the reducing spiral piece 68 is smoothly connected to the lifting spiral piece 67.
[0052] It should be noted that by rotating the sewage knob 64, the sewage shaft 65 and the sewage spiral 66, the lifting spiral 67 and the diameter-changing spiral 68 are driven to rotate, thereby achieving effective discharge of sand and soil, and the setting of the lifting spiral 67 ensures the effective removal of sand and soil during the process of pipe diameter change.
[0053] In an optional embodiment, a water level sensor 41 is provided in the sump 40 , and the water level sensor 41 is electrically connected to an external alarm system.
[0054] It should be noted that by providing a water level sensor 41 to monitor the water level in real time and issue an early warning, it is convenient to deal with the problem of water accumulation in a timely manner.
[0055] The working principle of the present invention is as follows: groundwater enters the drainage mechanism 50 through the mesh-shaped through-hole 53 at the bottom of the drainage tube 51, while the filter sleeve 52 and the sand and gravel filter layer 30 block the sand and gravel to prevent blockage; the water flows into the drainage elbow 55 through the reducer 54, and flows to the sump 40 under the action of gravity through the slope-designed drainage pipe 56, and the end check valve 57 prevents backflow; the sand and soil accumulated in the drainage tube 51 is pushed to the sewage pipe 61 by the spiral sewage discharge component 60, and finally enters the sewage trough 101 for cleaning. The height design of the sewage outlet avoids water flow interference; the water level sensor 41 in the sump 40 monitors the water level in real time, triggers the alarm system, and handles the accumulated water in time.
[0056] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
