Description

Technical Field

[0001] The invention belongs to the technical field of underground building waterproofing, and in particular relates to an underground waterproofing system and a construction method thereof. Background Art

[0002] Due to the current shortage of land, buildings are expanding to high altitudes and also extending to underground layers, such as basements, culverts, tunnels, underground garages, etc. However, the waterproof leakage of underground buildings is different from the ordinary building waterproofing, and requires back waterproofing. The existing back waterproofing generally adopts the grouting method, but this method can only solve the problem temporarily. It only stops leaking at the grouting place, and it will continue to leak in other places. For drainage, existing underground waterproof buildings are mostly equipped with drainage pipes, but as the use time increases, the drainage pipes are easily blocked by silt; with the development of the times, building complexes are developing in the direction of large-scale, high-tech, multi-functional and intelligent.

[0003] China's public patent CN203007995U discloses a blind ditch under the basement floor, including a drainage pipe, multiple concrete layers, crushed stone and geotextile layers. After the accumulated water is filtered through the geotextile layer and crushed stone, it enters the drainage pipe and is discharged through the drainage pipe, thereby achieving the drainage of the accumulated water in the basement. However, in this setting, when the accumulated water enters the drainage pipe, it is always in direct contact with the upper concrete layer, and the outer layer of the upper concrete is in contact with the outside world, which is a public area for people to walk or place objects. When the bottom surface of the upper concrete is soaked by accumulated water for a long time, the overall strength of the upper concrete will be reduced, which will lead to unsafe and unreliable conditions for people to walk or place objects.

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This embodiment provides an underground waterproof system, such as Figure 1 As shown, it includes a drainage mechanism 100, a water storage mechanism 200 and a waterproof mechanism 300 placed under the basement, wherein the drainage mechanism 100 is arranged horizontally through the underground soil layer, and the drainage mechanism 100 is arranged directly above the water storage mechanism 200 and is arranged in communication with the water storage mechanism 200; the drainage mechanism 100 includes a drainage channel 110 and a drainage switch 120 placed on the drainage channel 110. The water storage mechanism 200 includes a water reservoir 210, and an overflow channel 220 placed above the water reservoir 210 and connecting the water reservoir 210 and the drainage channel 110; the water reservoir 210 is an inverted cone structure, the upper end surface of the water reservoir 210 is a small-diameter surface, and the lower end surface of the water reservoir 210 is a large-diameter surface; the overflow channel 220 is vertically arranged at the top of the upper end surface of the water reservoir 210, and an overflow switch 230 is arranged in the overflow channel 220. The waterproof mechanism 300 is arranged directly below the water reservoir 210; the waterproof mechanism 300 is connected to the water reservoir 210. The drainage channel 110 and the overflow channel 220 are connected by a three-way pipe; the drainage channel 110 is placed on both sides of the overflow channel 220 and is inclined downward relative to the overflow channel 220.

[0034] Furthermore, the angle θ between the drainage channel 110 on either side and the overflow channel 220 is not greater than 60°; preferably, the angle θ between the drainage channel 110 on either side and the overflow channel 220 is 45°. This angle makes it easier for the water overflowing from the water reservoir 210 through the overflow channel 220 to be discharged from the drainage channel 110.

[0035] like Figure 2 As shown, the drainage switch 120 is axially arranged along the length direction of the drainage channel 110, including a conical support platform 121 placed on the inner side of the drainage channel 110, a drainage spring 122 that passes through the conical support platform 121 and is located on its axis, and a spherical water stopper 123 placed on the upper end surface of the conical support platform 121 and connected to one end of the drainage spring 122. The large end surface of the conical support platform 121 is arranged away from one end of the spherical water stopper 123.

[0036] Furthermore, the drainage switch 120 is provided with a gap between the outer wall of the conical support platform 121 and the inner wall of the drainage channel 110, forming a symmetrically distributed first water channel 124 and a second water channel 125, the first water channel 124 and the second water channel 125 are connected to the overflow channel 220 at one end away from the spherical water stopper 123, the first water channel 124 and the second water channel 125 are confluently arranged near one end of the spherical water stopper 123, and are both interconnected with the drainage channel 110, that is, the spherical water stopper 123 is arranged at the water inlet of the drainage channel 110, and the spherical water stopper 123 is elastically connected to the top wall of the conical support platform 121 through the drainage spring 122, and the expansion and contraction direction of the drainage spring 122 is the same as the water flow direction at the water inlet of the drainage channel 110.

[0037] like Figure 3 As shown, the overflow switch 230 is arranged along the height direction of the overflow channel 220, including a fixed plate 231 placed inside the overflow channel 220, a connecting column 232 arranged through the fixed plate 231, and an outer baffle 234 and an inner baffle 235 fixedly arranged at both ends of the connecting column 232, wherein a plurality of overflow water-guiding through holes 233 are arranged on the fixed plate 231 and around the connecting column 232, preferably, the water-guiding through holes 233 are fan-shaped structures and are evenly distributed along the circumference, which are omitted in the figure; the outer baffle 231 is placed outside the upper end surface of the overflow channel 220, and the inner baffle 235 is placed on the inner side of the overflow channel 220 close to the water reservoir 210. An overflow spring 236 is arranged between the fixing plate 231 and the inner baffle 235 on the connecting column 232, and the connecting column 232 passes through the overflow spring 236. The diameter of the outer baffle plate 234 is greater than the diameter of the inner baffle plate 235 , and the diameter of the outer baffle plate 234 is greater than the diameter of the overflow channel 220 , and the diameter of the inner baffle plate 235 is smaller than the diameter of the overflow channel 220 .

[0038] like Figure 1 As shown, the waterproof mechanism 300 is mainly used for waterproofing, including a horizontally arranged leaking plate 310 and a plurality of waterproof cavities 320 arranged at intervals below the leaking plate 310. The leaking plate 310 is located at the lower end surface of the water reservoir 210, and a plurality of leaking holes are arranged on the leaking plate 310. The leaking plate 310 is connected to the water reservoir 210 through the leaking holes. The waterproof cavity 320 is composed of channel steels arranged in position, and a layer of concrete is laid at the bottom of the waterproof mechanism 300, that is, on the bottom surface of the waterproof cavity 320, and the interior of the waterproof cavity 320 is filled with waterproof material, which is one of waterproof mortar or waterproof coating, and is used to prevent moisture from flowing and prevent the water storage mechanism 200 above from collapsing. The setting of the waterproof mechanism 300 can separate the basement floor from the water storage mechanism 200, thereby avoiding direct contact between the area with accumulated water and the basement floor, thereby avoiding the phenomenon that the basement floor is damaged and rotted after long-term contact with accumulated water, thus ensuring the service life of the basement floor.

[0039] When in use, when the accumulated water penetrates through the concrete layer, it first passes through the waterproof mechanism 300. When the waterproof mechanism 300 is not enough to block the water or the waterproof mechanism 300 is damaged, the accumulated water will pass through the reservoir 210. If there is too much accumulated water in the reservoir 210, the accumulated water will enter the overflow channel 220. The overflow switch 230 set in the overflow channel 220 is pushed by the pressure of water. The water pressure pushes the inner baffle 235 to overcome the elastic force of the sealed overflow spring 236, so that the inner baffle 235 moves upward under the guidance of the lifting connecting column 232, thereby releasing the seal of the overflow channel 220 by the outer baffle 234, so as to facilitate the emptying of the accumulated water in the reservoir 210. When it is not necessary to drain, the inner baffle 235 is restored to its original position under the action of the sealed overflow spring 236, and the outer baffle 234 is set outside the overflow channel 220. At this time, the outer baffle 234 seals the overflow channel 220. When the accumulated water flows from the overflow channel 220 to the drainage channel 110, the water pressure forces the spherical water stopper 123 to move to the side away from the water overflow channel 220, and the spherical water stopper 123 presses the drainage spring 122 to move toward the large port side of the conical support platform 121, so that there is a gap between the spherical water stopper 123 and the water inlet of the overflow switch 230, causing the water inlet of the overflow switch 230 to be connected with the first water channel 124 and the second water channel 125, and the accumulated water flows out from the first water channel 124 and the second water channel 125.
