Description
Technical Field
[0001] The invention relates to the field of building waterproof facilities, in particular to a waterproof, moisture-proof and mildew-proof basement structure. Background Art
[0002] A basement is a room whose floor is lower than the outdoor ground level by more than half of the room's net height. Multi-story and high-rise buildings require a deeper foundation. To utilize this height, a basement is built under the bottom floor of the building, which can increase the usable area and save the backfill soil in the center of the house. Building a basement below the bottom floor of the house can improve the efficiency of building land. Some high-rise buildings have a very deep burial depth. Making full use of this depth to build a basement has excellent economic and practical effects. Basements are divided into ordinary basements and air-raid basements according to their functions; according to structural materials, there are brick wall structure and concrete structure basements; according to structural forms, there are full basements and semi-basements.
[0003] Traditional basements are all concrete structures. When the basement is poured and the soil is backfilled, the soil is relatively soft, which makes it easy for natural water from the outside to seep into the ground. Since concrete is a material full of cracks, some of the natural water that seeps into the ground seeps into the basement, causing water to enter the basement, and the moisture increases, which is easy to cause mold. Therefore, during the construction of the basement, the components of waterproof facilities are particularly important. Traditional basement waterproof facilities use water-proofing to prevent, that is, laying and painting waterproof coatings on the inner facade (or outer wall) of the basement to achieve the effect of waterproofing, moisture-proofing and mildew-proofing in a "blocking" manner. However, in actual use, this method is affected by the environment and geographical location, and its service life itself has uncertain factors, and later maintenance and construction are difficult.

DETAILED DESCRIPTION
[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0017] In addition, the terms used below are defined based on the functions of the present invention and may differ depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.
[0018] See also Figure 1-8 The waterproof, moisture-proof and mildew-proof basement structure of the present invention comprises a side wall 1 and a bottom plate 2, both of which are cast and formed by concrete, and a water filter pipe 13 is pre-buried at the inner corner of the side wall 1 and the bottom plate 2, and the cross section of the water filter pipe 13 is square, and sand and gravel can be laid on the inner side of the water filter pipe 13, and the two ends of the water filter pipe 13 are welded and blocked by metal cover plates, and water diversion holes 11 are opened at equal distances in the horizontal direction at the lower position of the side wall 1, and the water diversion holes 11 can be opened by drilling equipment; A water diversion pipe 12 is installed inside the water diversion hole 11, and the natural water in the soil outside the side wall 1 can enter the water filter pipe 13 through the water diversion pipe 12, and the water filter pipe 13 is connected to the outside of the side wall 1 through the water diversion pipe 12. The two end positions near the water filter pipe 13 are connected to the water collecting box 3 through the connecting pipe 31. The natural water entering the water filter pipe 13 enters the water collecting box 3 through the connecting pipe 31. The natural water in the external soil is isolated by drainage, so that the water absorption of the side wall 1 and the bottom plate 2 is reduced, and the waterproof effect of the basement is achieved. The isolation of natural water also reduces the humidity inside the basement, and the dry basement environment is not easy to produce mold; A part of the water collecting tank 3 is pre-buried inside the base plate 2, a water pump 4 is arranged at the center of the water collecting tank 3, the water outlet of the water pump 4 is extended to the outdoors through an external pipe, the open end of the water collecting tank 3 is sealed by a cover plate 32, a positioning plate 41 is horizontally installed at the upper position of the inner wall of the water collecting tank 3, a cross rod 42 is inserted in the positioning plate 41, a floating block 43 is connected to the bottom of the cross rod 42, a float switch 44 is connected to one side of the floating block 43, and the float switch 44 is electrically connected to the water pump 4, as the liquid level in the water collecting tank 3 rises, the floating block 43 drives the float switch 44 to rise synchronously under the action of buoyancy, the cross rod 42 moves up along the positioning plate 41, when it rises to a certain height, the float switch 44 is triggered, the water pump 4 works and pumps out the natural water in the water collecting tank 3, so as to achieve the effect of water level monitoring and automatic drainage of the water collecting tank 3; It should be noted that the "rising to a certain height" mentioned above refers to the working height of the float switch 44, which is normally set to three quarters of the height of the water collecting tank 3. The float switch 44 is selected to be a model with adjustable working height. The water diversion pipe 12 is composed of an outer sleeve 121 and an inner pipe 122. The outer sleeve 121 is arranged obliquely on the inner wall of the water diversion hole 11. The two end ends of the inner pipe 122 are welded to the inner wall of the outer sleeve 121. A filter screen 123 is built into the outer end of the inner pipe 122 facing the outer wall 1. The central pipeline of the inner pipe 122 is U-shaped. When the water diversion pipe 12 is in operation, when natural water in the soil flows through the inner pipe 122, part of the natural water will be stored in the U-shaped area. This part of natural water can isolate and seal the inner cavity of the inner pipe 122, thereby preventing part of the odor in the soil from entering the water collecting tank 3 through the water diversion pipe 12. When there is a sealing problem in the water collecting tank 3, the odor will not spread to the basement.
[0019] In another embodiment, see Figure 1 , Figure 4 and Figure 5A drainage pipe 5 is arranged at a lower position on the outer side of the measuring wall 1, and a circular arc groove 51 is opened on the top of the drainage pipe 5. A support rod 52 is arranged at an equal angle between the two end surfaces of the circular arc groove 51. The inner and outer sides of the support rod 52 are covered with a water-permeable membrane 53, and the surrounding of the water-permeable membrane 53 is embedded in the circular arc groove 51. The outer wall of the drainage pipe 5 is arranged with a connecting pipe 54 at an equal distance along the pipe diameter direction, and one end of the connecting pipe 54 is connected to the water diversion pipe 12. The placement position of the drainage pipe 5 can be understood as the outer wall root of the measuring wall 1, and the opening of the drainage pipe 5 extends To the external environment of the basement, when the water content in the soil is low, the natural water in the soil will enter the drain pipe 5 through the permeable membrane 53 and flow along the drain pipe 5 to the external environment. When the water content in the soil is large (such as rainy weather), a large amount of natural water will flow into the drain pipe 5, and the natural water flow rate flowing in the drain pipe 5 is large, and the liquid level rises to the level of the connecting pipe 54. At this time, the natural water in the drain pipe 5 will enter the water collecting tank 3 through the connecting pipe 54, so that the drainage pressure of the water diversion pipe 12 can be effectively shared through the connecting pipe 54.
[0020] like Figure 4 and Figure 5 As shown, support rods 55 are installed at equal distances at the bottom of the outer wall of the drainage pipe 5, and discs 56 are welded at equal distances on the outer wall of the support rod 55. A support 57 is connected to the bottom of the support rod 55. The drainage pipe 5, the support rod 55, the disc 56 and the support 57 are all pre-buried in the soil. The support 57 can be constructed together with the wall 1 when pouring. The disc 56 increases the contact area with the soil, that is, the support 57 and the disc 56 are used to start the anti-settling effect of supporting the drainage pipe 5.
[0021] In another embodiment, see Figure 1-Figure 8 A sealing shell 61 is fixedly installed on the top of the cover plate 32 by bolts, a through hole 611 is opened on the top of the sealing shell 61, a positioning block 63 is fixedly installed concentrically inside the sealing shell 61, and a placement hole 64 is opened at the center of the top of the positioning block 63, and the external pipe of the water pump 4 can be connected to the external environment through the placement hole 64; The bottom of the positioning block 63 is symmetrically provided with triangular grooves 35 at equal angles, a rectangular groove 66 is provided at the top of the triangular groove 35, a triangular plate 67 is provided directly below the triangular groove 65, and the triangular plate 67 is connected and fixed to the positioning block 63 through an L-shaped rod, and the triangular plate 67 and the triangular groove 35 are combined to form a flip channel, and a rotating ring block 62 is rotatably installed at the outer concentric position of the positioning block 63, and the bottom of the rotating ring block 62 passes through the cover plate 32 and is located in the center of the water collecting tank 3, and the internal cavity of the rotating ring block 62 can accommodate the water pump 4; The bottom outer wall of the rotating ring block 62 is provided with arc grooves 621 at equal angles in the circumferential direction. Two adjacent arc grooves 621 are connected by vertical grooves 622. The arc grooves 621 and the vertical grooves 622 are combined into an offset channel. The rotating ring block 62 is located at the upper position and is rotatably mounted with a rotating shaft 68 on all sides. The outer end of the rotating shaft 68 is fixedly connected with a storage box 69. A desiccant 691 is placed in the storage box 69. The desiccant 691 can be a colored silica gel desiccant. The humid gas in the basement can contact the desiccant 691 through the through hole 611. The moisture in the basement is adsorbed by the desiccant 691, which further increases the moisture-proof and mildew-proof effect of the basement. The colored silica gel desiccant can be judged by observing its color change to determine whether it is fully absorbed. The inner end of the rotating shaft 68 is connected to the arc plate 60, and the inner concave surface of the arc plate 60 is symmetrically installed with a limit rod 601. Figure 7 As shown, taking the L end of the limit rod 601 entering the flip channel first as an example, the top of the cross rod 42 is plugged with an extrusion rod 45, one end of the extrusion rod 45 is located in the vertical groove 622, and a return spring 46 is installed at the connection between the extrusion rod 45 and the cross rod 42. The elastic force of the return spring 46 pushes the extrusion rod 45 to be close to the vertical groove 622, and the lateral depth of the arc groove 621 relative to the rotating ring block 62 gradually increases from bottom to top, that is, the arc groove 62 is connected to the top of the vertical groove 622. There is a lateral drop at the bottom of the arc groove 621 and the connecting surface of the vertical groove 622. It can be understood that when the extrusion rod 45 slides in the offset channel, when it moves from the lowest point to the highest point, the extrusion rod 45 slides in the vertical groove 622, and vice versa, it slides in the arc groove 621. When the water pump 4 enters the drainage operation, the cross rod 42 drives the extrusion rod 45 to be located at the top of the vertical groove 622 (which is also the top of the arc groove 621, and the two are continuously connected) under the action of the floating block 43. The return spring 46 pushes the extrusion rod 45 into the arc groove 621. The extrusion rod 45 squeezes the inner wall of the arc groove 621 so that the rotating ring block 62 rotates concentrically on the outer wall of the positioning block 63. The L end of the limit rod 601 will enter the flip channel and slide along the top of the triangular plate 67. When the L end of the limit rod 601 slides to the top of the triangular plate 67, it will enter the rectangular groove 66. At this time, the L end position of the limit rod 601 is temporarily locked by the rectangular groove 66, and the rotating ring block 62 continues to rotate. The R end of the rotating limit rod 601 will pass through the bottom of the triangle plate 67 and drive the L end of the limit rod 601 to separate from the rectangular groove 66 and slide along the triangle plate 67 to the lower end surface of the positioning block 63. In this process, the positions of the L end and the R end of the limit rod 601 are reversed, that is, the rotating shaft 68 rotates 180°, and the desiccant 691 placed in the storage box 69 turns over and shakes, which can increase the adsorption efficiency of the desiccant 691 and ensure that the desiccant 691 at each position can fully absorb moisture.
[0022] like Figure 1As shown, the connection between the outer sleeve 121 and the water diversion hole 11 is coated with a waterproof coating to increase the sealing between the outer sleeve 121 and the water diversion hole 11, and the outer sleeve 121 is a component made of corrosion-resistant material, which extends the service life of the outer sleeve 121.
[0023] The cover plate 32 and the water collecting tank 3 are locked and fixed by a clamp to ensure the sealing of the two while facilitating the opening of the cover plate 32 and facilitating the maintenance of components such as the water pump 4. An O-ring is installed at the connection between the sealing shell 61 and the cover plate 32 to increase the sealing between the sealing shell 61 and the cover plate 32 and prevent the natural water stored in the water collecting tank 3 from evaporating into the basement environment along the gap between the two.
[0024] In another embodiment, see Figure 1 and 3 A brush is embedded in the outer wall of the floating block 43, and the brush is in contact with the inner wall of the water collecting tank 3 but not connected. The brush can move synchronously with the rise and fall of the floating block 4, and scrape the inner wall of the water collecting tank 3 during the movement, thereby reducing the generation of scale and other attachments on the inner wall of the water collecting tank 3.
