Description

Technical Field

[0001] This utility model belongs to the field of underground building waterproofing technology, specifically relating to an underground anti-seepage device for buildings. Background Technology

[0002] Due to the large-scale development of underground buildings, underground architecture is taking shape. It is a product of the rapid development of modern cities, playing a role in alleviating urban conflicts and improving the living environment. It also opens up new living areas for mankind. Its research content includes the history and development direction of underground buildings, the development and utilization of underground space, the comprehensive planning of urban underground space, the planning and design of various underground buildings, as well as the environmental, physiological, psychological and technical aspects related to underground buildings.

[0003] Underground buildings are structures built in rock or soil layers. The underground structure of a building mainly includes the foundation and the side walls on top of the foundation. During rainy or snowy weather, rainwater can seep into the side walls of the underground structure. The rainwater that accumulates around the side walls can easily seep into the interior of the walls, leading to water leakage.

[0004] Currently, the most common methods to prevent water seepage are to add a waterproof membrane or apply a waterproof coating to the exterior wall. However, with prolonged use, the waterproof membrane or coating may be corroded or damaged. Additionally, due to other external factors, such as the periodic rainy season causing a significant amount of water to accumulate on the exterior of the wall, there is still a high risk of water leakage. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a seepage prevention device for underground buildings, which aims to enable underground buildings to cope with corrosion and damage to waterproof membranes or waterproof coatings, or to ensure smooth waterproofing and drainage even when rainfall increases suddenly in a short period of time during the rainy season.

[0006] To achieve the above objectives, this utility model proposes an underground anti-seepage device for buildings, comprising a water storage mechanism, a seepage mechanism, and a drainage mechanism. The water storage mechanism is sleeved around the foundation of the underground building, and the seepage mechanism is located on the top and outer wall of the underground building. The water storage mechanism has a water storage cavity inside, and the seepage mechanism has a connected guide cavity and a seepage structure. The seepage structure is used to connect the guide cavity with the outside. The bottom end of the seepage mechanism is connected to the water storage mechanism so that the guide cavity connects to the water storage cavity. One end of the drainage mechanism is connected to the water storage mechanism and has a drainage channel inside that connects to the water storage cavity.

[0007] Optionally, the seepage mechanism includes a manifold and multiple seepage pipes. The manifold is located at the top of the underground structure, and one end of each of the multiple seepage pipes is connected to the outer periphery of the manifold, while the other end extends downward from multiple sides of the underground structure to connect to the water storage mechanism.

[0008] Optionally, the manifold is provided with a connected manifold cavity and multiple water filters, with the multiple water filters spaced apart on the side of the manifold facing away from the underground structure.

[0009] Optionally, the seepage structure is configured as a filter plate, the filter plate having multiple water outlets, and each seepage pipe having multiple filter plates spaced apart.

[0010] Optionally, the water storage mechanism is a ring-shaped rectangular pipe, the seepage mechanism is an L-shaped rectangular pipe, and multiple L-shaped rectangular pipes are located at one end of the top of the underground building and converge to the manifold. The wall thickness of the water storage mechanism is greater than or equal to the wall thickness of the seepage pipe.

[0011] Optionally, the water storage mechanism is provided with at least one connection port on each side wall of the underground building, each seepage pipe is connected to one of the connection ports, and each connection port is provided with a filter element.

[0012] Optionally, the filter element is disposed at one end of the seepage pipe; or, the filter element is disposed on the water storage mechanism.

[0013] Optionally, the drainage mechanism includes a pumping pipe, a pump, and a drain pipe. One end of the pumping pipe is connected to the water storage mechanism, and the other end of the pumping pipe extends upward and is connected to the inlet of the pump. The drain pipe is connected to the outlet of the pump.

[0014] Optionally, both the water storage mechanism and the water seepage mechanism are made of seamless steel pipe.

The water storage mechanism is fitted around the foundation of the underground building, while the seepage mechanism is located on the top and outer wall of the underground building. The water storage mechanism has a water storage chamber, and the seepage mechanism has a connected guide chamber and a seepage structure. The bottom end of the seepage mechanism is connected to the water storage mechanism, allowing the guide chamber to connect to the water storage chamber. One end of the drainage mechanism is connected to the water storage mechanism and has a drainage channel connecting to the water storage chamber. The seepage structure connects the guide chamber to the outside environment. The cooperation of the water storage mechanism, seepage mechanism, and drainage mechanism can promptly drain accumulated water when the outer waterproof membrane or waterproof coating of the building is corroded or damaged.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0019] Due to the large-scale development of underground buildings, underground architecture is taking shape. It is a product of the rapid development of modern cities, playing a role in alleviating urban conflicts and improving the living environment. It also opens up new living areas for mankind. Its research content includes the history and development direction of underground buildings, the development and utilization of underground space, the comprehensive planning of urban underground space, the planning and design of various underground buildings, as well as the environmental, physiological, psychological and technical aspects related to underground buildings.

[0020] Underground buildings are structures built in rock or soil layers. The underground structure of a building mainly includes the foundation and the side walls on top of the foundation. During rainy or snowy weather, rainwater can seep into the side walls of the underground structure. The rainwater that accumulates around the side walls can easily seep into the interior of the walls, leading to water leakage.

[0021] Currently, the most common methods to prevent water seepage are to add a waterproof membrane or apply a waterproof coating to the exterior wall. However, with prolonged use, the waterproof membrane or coating may be corroded or damaged. Additionally, due to other external factors, such as the periodic rainy season causing a significant amount of water to accumulate on the exterior of the wall, there is still a high risk of water leakage.

[0022] To achieve the above objectives, this utility model provides a building underground anti-seepage device 100, including a water storage mechanism 10, a seepage mechanism 30, and a drainage mechanism 50, as shown in the reference. Figure 1As shown, the water storage mechanism 10 is installed around the foundation of the underground structure 900, and the seepage mechanism 30 is installed on the top and outer wall of the underground structure 900. The water storage mechanism 10 has a water storage cavity, and the seepage mechanism 30 has a connected guide cavity and a seepage structure 35. The seepage structure 35 is used to connect the guide cavity with the outside. The bottom end of the seepage mechanism 30 is connected to the water storage mechanism 10 so that the guide cavity is connected to the water storage cavity. One end of the drainage mechanism 50 is connected to the water storage mechanism 10 and has a drainage channel connected to the water storage cavity.

[0023] This utility model comprises a water storage mechanism 10, a seepage mechanism 30, and a drainage mechanism 50. The water storage mechanism 10 is fitted around the foundation of the underground structure 900, and the seepage mechanism 30 is located on the top and outer wall of the underground structure 900. The water storage mechanism 10 has a water storage cavity, and the seepage mechanism 30 has a connected guide cavity and a seepage structure 35. The bottom end of the seepage mechanism 30 is connected to the water storage mechanism 10, allowing the guide cavity to connect with the water storage cavity. One end of the drainage mechanism 50 is connected to the water storage mechanism 10 and has a drainage channel connecting to the water storage cavity. The seepage structure 35 connects the guide cavity to the outside. The cooperation of the water storage mechanism 10, the seepage mechanism 30, and the drainage mechanism 50 can promptly drain accumulated water when the outer waterproof membrane or waterproof coating of the building is corroded or damaged. It can also quickly guide the water accumulated around the underground structure 900 in a short period of time to the water storage cavity and smoothly drain it through the drainage mechanism 50, avoiding the risk of water leakage or seepage in the underground structure 900 due to damage to the waterproof coating or a sudden increase in water volume in a short period of time.

[0024] It should be noted that the anti-seepage device 100 of this utility model is a water collection and drainage structure added on the basis of the outer layer of the underground building 900 having a water-proof film or waterproof coating. It can quickly collect and discharge water to prevent the underground building 900 from being soaked in water.

[0025] Optionally, the seepage mechanism 30 includes a manifold 31 and a plurality of seepage pipes 33. The manifold 31 is located at the top of the underground structure 900. One end of the plurality of seepage pipes 33 is connected to the outer periphery of the manifold 31, and the other end extends downward from a plurality of sides of the underground structure 900 to connect to the water storage mechanism 10.

[0026] In this embodiment, the manifold 31 is located at the center of the outer top wall of the underground building 900, which can collect the water accumulated on the top of the underground building 900. Multiple seepage pipes 33 are attached to the outer top wall and outer side wall of the underground building 900, which can guide and collect the water collected on the top wall and side wall of the underground building 900, and then merge it together with the water in the manifold 31 into the water storage chamber of the water storage mechanism 10, and then discharge it through the drainage mechanism 50, thereby quickly draining the water and preventing the water from accumulating for a long time and causing leakage.

[0027] Optionally, the manifold 31 is provided with a connected manifold cavity and a plurality of water filter ports 31A, which are spaced apart on the side of the manifold 31 facing away from the underground building 900.

[0028] In this embodiment, the manifold 31 can be a square, circular, or other shaped box. The manifold 31 has a manifold cavity inside. When the wall thickness of the manifold 31 is small, multiple water inlets 31A can be provided on the top of the manifold 31. When the wall thickness of the manifold 31 is large, multiple water inlets 31A can be provided on the top and sides of the manifold 31, avoiding the seepage pipe 33. The water inlets 31A are used to connect the manifold cavity to the outside. They can collect the water accumulated on the top of the underground building 900 and guide it out to the water storage cavity through the seepage pipe 33. With the help of the seepage pipe 33, the water accumulated on the top of the underground building 900 can be quickly treated, avoiding the problem of water leakage caused by long-term water accumulation on the top.

[0029] Optionally, the seepage structure 35 is configured as a filter plate 351, with multiple water outlets 31A on the filter plate 351, and multiple filter plates 351 are spaced apart on each seepage pipe 33.

[0030] In this embodiment, the seepage structure 35 is disposed on the seepage pipe 33. The seepage structure 35 can be a filter screen plate 351 with multiple filter ports 31A, or it can be a mesh structure with multiple filter ports 31A directly opened on the seepage pipe 33. Multiple filter screen plates 351 or multiple mesh structures are disposed at intervals on each seepage pipe 33, which can collect the water accumulated on the extension path of the seepage pipe 33 in sections and improve the water collection efficiency.

[0031] Optionally, the water storage mechanism 10 is a ring-shaped rectangular pipe, and the seepage mechanism 30 is an L-shaped rectangular pipe. Multiple L-shaped rectangular pipes are located at one end of the top of the underground building 900 and are connected to the manifold 31. The wall thickness of the water storage mechanism 10 is greater than or equal to the wall thickness of the seepage pipe 33.

[0032] In this embodiment, the water storage mechanism 10 is a ring-shaped rectangular pipe, allowing it to be installed around the periphery of the underground structure 900. The seepage mechanism 30 is an L-shaped rectangular pipe. Using rectangular pipes allows for increased width while maintaining the same flow rate, thus reducing the wall thickness of the pipe. Compared to circular pipes, this design allows for more flexible arrangement. The wall thickness of the rectangular pipe in the water storage mechanism 10 is greater than or equal to the wall thickness of the seepage pipe 33. This increases the water storage capacity, while the smaller wall thickness of the seepage pipe 33 reduces the likelihood of it being scratched or bumped by external objects, improving the water collection reliability of the anti-leakage device 100.

[0033] Optionally, both the water storage mechanism 10 and the water seepage mechanism 30 are made of seamless steel pipes, and anti-rust paint or anti-rust coating can be applied to the outer periphery of the seamless steel pipes.

[0034] Optionally, the water storage mechanism 10 is provided with at least one connection port on each side wall of the underground building 900, and each seepage pipe 33 is connected to a connection port, with a filter element provided at each connection port.

[0035] In this embodiment, an L-shaped seepage pipe 33 can be installed on one side wall of the underground building. If the underground building 900 has a large structural volume, multiple seepage pipes 33 can also be installed on one side wall. Each seepage pipe 33 is provided with a connection port, which can make multiple seepage pipes 33 smoothly connected to the water storage structure.

[0036] The filter element is located at the connection port to filter the water collected in the seepage pipe 33 and the manifold 31 before it enters the water storage chamber, so as to prevent the water containing large particles of residue from forming sediment or clogging the drainage mechanism 50.

[0037] Furthermore, when multiple seepage pipes 33 are provided on one side wall, the multiple seepage pipes 33 can use separate connection ports, that is, the multiple seepage pipes 33 can be arranged in parallel, or the upper part of two adjacent seepage pipes 33 can be branched, and the lower part can share a pipe for water collection. In this case, a connection port is used to connect the water storage chamber. For example, the multiple seepage pipes 33 can be arranged in a Y-shape.

[0038] Optionally, the filter element is located at one end of the seepage pipe 33; or, the filter element is located on the water storage mechanism 10.

[0039] In this embodiment, the filter element can be a screen that is welded or detachably connected to one end of the seepage pipe 33, or a screen that is welded or detachably connected to the top of the annular pipe of the water storage mechanism 10, for filtering accumulated water.

[0040] Optionally, the drainage mechanism 50 includes a pumping pipe 51, a pump (not shown) and a drain pipe (not shown). One end of the pumping pipe 51 is connected to the water storage mechanism 10, and the other end of the pumping pipe 51 extends upward and is connected to the inlet end of the pump. The drain pipe is connected to the outlet end of the pump.

[0041] In this embodiment, the water pump and drain pipe can be installed on the ground or in a dedicated drainage well; their installation locations are not limited to a single location. Drainage can be discharged into a dedicated water tank or connected to a sewer system; these options are also not limited to a single location.

[0042] The water pump is started, and the accumulated water in the annular rectangular pipe is pumped out through the water pump 51 and flows into the water storage tank or underground drainage channel through the water pump and delivery pipe, so as to prevent a considerable amount of water from accumulating around the walls of the underground building 900 and effectively reduce the risk of water leakage.

[0043] In this utility model, the terms "inner", "outer", "upper", "lower", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "fix," and "connect" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
