Description

Technical Field

[0001] The present application relates to the technical field of underground building waterproof engineering, and in particular to an anti-leakage structure and construction process for a floor without a bottom plate for an underground garage. Background Art

[0002] At present, most underground garages are equipped with waterproof layers, structural bottom plates (made of impermeable concrete) and fine stone concrete floors, and multiple protective measures are taken to ensure the waterproof performance of the entire garage. These waterproof systems effectively resist the penetration of groundwater, ensure the safety and dryness of the interior of the garage, and thus extend the overall service life of the garage.

[0003] In the related technology, the waterproofing measures for underground garages mainly include laying a waterproof layer, pouring impermeable concrete as the structural base plate, and setting a fine stone concrete floor on it. Among them, the waterproof layer is used to prevent groundwater from directly penetrating into the garage; the impermeable concrete base plate not only plays a supporting role, but also has a good waterproof function; the fine stone concrete floor further improves the surface flatness and durability.

[0004] Regarding the above-mentioned related technologies, this traditional waterproof system relies on the multi-layer superposition effect to achieve the ultimate waterproof goal. Once a certain layer fails, it may cause the overall waterproof performance to decline. If the amount of water accumulation is large, if the concrete layer is cracked, the accumulated water will seep in and affect the service life of the garage. For this reason, there is an urgent need for a structure that can still drain water when there is a large amount of water accumulated in the basement, thereby reducing leakage. Summary of the invention

[0005] In order to be able to drain water when there is a large amount of water accumulated in the basement, the present application provides an anti-leakage structure for the floor without a bottom plate in an underground garage.

[0007] By adopting the above-mentioned technical scheme, the present application sets up a drainage component. When the amount of accumulated water is small, the accumulated water flows into the first water collecting member along the inclined direction of the first guide part, and part of the water enters the bottom wall of the drainage layer from the first drainage hole, and further enters the first water collecting member. The solid impurities in the water are filtered by the first drainage hole to reduce the blockage of the first drainage hole by impurities, which leads to the inability to discharge the accumulated water. If the amount of accumulated water is large, the pressure generated by the accumulated water is applied to the first guide part to rotate the end of the first guide part close to the first water collecting member toward the side away from the first water collecting member, so that there is a water gap between the guide part and the inner wall of the drainage area, which is convenient for the accumulated water to be discharged into the first water collecting member, and reduces the accumulation of accumulated water in the drainage area and causes it to penetrate into the lower layer.

[0008] Optionally, the drainage assembly also includes a first elastic member, one end of which is fixedly connected to the first guide portion, and the other end is fixedly connected to the inner wall of the drainage area, and the first elastic member has a force driving the first guide portion to rotate toward a side away from the waterproof base layer under recoverable deformation.

When pressure acts on the first guide part, the deformation of the first elastic member gradually increases, and the end of the first guide part close to the second side wall tends to move toward the first side wall. A water gap is provided between the end of the first guide part close to the first water collecting member and the inner wall of the drainage area, so that the accumulated water flows from the water gap into the first drainage member. When the pressure gradually decreases, under the action of the first elastic member, one end of the first guide part gradually returns to a state of contact with the inner wall of the drainage area.

When the amount of accumulated water is large, pressure acts on the second guide part to make the end of the second guide part change from a contact state with the inner wall of the first water collecting part to a non-contact state, so that the accumulated water can enter the first water collecting part.

[0012] Optionally, it further includes a pushing plate, which is in contact with the bottom wall of the drainage layer and is slidably connected to the drainage layer along a third direction, and the third direction is perpendicular to both the first direction and the second direction.

[0018] Optionally, a cleaning plate is further included, wherein the cleaning plate is arranged on the first air guide portion, and the cleaning plate slides along the inclined direction of the first air guide portion.

[0019] By adopting the above technical solution, since the impurities in the accumulated water will be filtered by the first water collecting member and remain on the first guide part, the impurities may block the first drainage hole under the flushing of the accumulated water.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-7 This application is described in further detail.

[0030] The present application embodiment discloses an anti-leakage structure for a floor without a bottom plate in an underground garage. Figure 1 and Figure 2The anti-seepage structure of the bottomless floor of the underground garage includes a concrete layer 1, a gravel layer 2, a drainage layer 3, a waterproof base layer 4 and a structural layer 5 arranged in sequence along a first direction. The drainage layer 3 is penetrated with a drainage area 31 along the first direction. The drainage area 31 includes a first side wall 311 and a second side wall 312 parallel to each other. A drainage component 32 is arranged in the drainage area 31. The drainage component 32 includes a first guide part 321 and a first water collecting part 322. One end of the first guide part 321 is rotatably connected to the drainage layer 3. The outer peripheral wall of the first guide part 321 is fitted with the inner peripheral wall of the shooting area 31. The first guide part 321 is parallel to the second direction along the rotation axis of the drainage layer 3, and the second direction is perpendicular to the first direction. The first guide part 321 is penetrated with a first side wall 311 and a second side wall 312 parallel to each other. A drainage hole 3211, a first guide portion 321 is inclined from the first side wall 311 to the second side wall 312 along the direction of the concrete layer 1 to the structural layer 5, and a first water collecting member 322 is openly arranged, the first water collecting member 322 is connected to the drainage area 31, and the first water collecting member 322 is arranged on the side of the drainage member close to the second side wall 312; the gravel layer 2 has a certain density, which can fill the pores or tiny holes on the concrete layer 1 to form an additional barrier to effectively prevent rainwater or accumulated water from leaking. If there is still accumulated water leaking from the gravel layer 2 and further entering the drainage area 31, the first guide portion 321 is inclined to guide the accumulated water, so that the accumulated water further enters the first water collecting member 322, thereby reducing further leakage of the accumulated water; Reference Figure 2 When the amount of accumulated water is small, the accumulated water flows into the first water collecting member 322 along the inclined direction of the first guide portion 321, and part of the water enters the bottom wall of the drainage layer 3 through the first drainage hole 3211, and further enters the first water collecting member, and the solid impurities in the water are filtered by the first drainage hole 3211 to reduce the blockage of the first drainage hole 3211 by impurities, thereby causing the accumulated water to be unable to be discharged. If the amount of accumulated water is large, the accumulated water presses the first guide portion 321 to move the end of the first guide portion 321 close to the second side wall 312 close to the first side wall 311, so that there is a water gap between the guide portion and the second side wall 312, which is convenient for the discharge of accumulated water.

[0031] Reference Figure 2 and Figure 3In order to restore the first guide part 321 to its initial position, the drainage component 32 further includes a first rotating shaft 323 and a first elastic member 324. One end of the first guide part 321 close to the first side wall 311 is rotatably connected to the drainage layer 3 through the first rotating shaft 323. Specifically, the first guide part 321 is provided with a first through hole 3212 along the second direction. In order to ensure that the first guide part 321 can rotate with the first rotating shaft 323, the shaft hole tolerance between the first through hole 3212 and the first rotating shaft 323 is an interference fit, so as to fix the first rotating shaft 323 to the first guide part 321. A guide portion 321 is further provided with a second through hole 3213 for accommodating a first elastic member 324, the second through hole 3213 is coaxially arranged with the first through hole 3212, the first elastic member 324 is sleeved on the outer periphery of the first rotating shaft 323, one end of the first elastic member 324 is fixedly connected to the inner peripheral wall of the drainage area 31, and the other end is fixedly connected to the first rotating shaft 323. In this embodiment, the first elastic member 324 is a torsion spring, and the end of the first guide portion 321 that contacts the first side wall 311 is semicircular. Under different forces, the positional relationship of the first guide portion 321 relative to the drainage area 31 is also different, as follows: When the first elastic member 324 is slightly deformed, the first flow guide portion 321 and the peripheral wall of the drainage area 31 are completely fitted together; When pressure acts on the first guide portion 321, the deformation of the first elastic member 324 gradually increases, and the end of the first guide portion 321 close to the second side wall 312 tends to move toward the first side wall 311. A water gap is provided between the end of the first guide portion 321 close to the second side wall 312 and the second side wall 312, so that the accumulated water flows into the first water collecting member 322 through the water gap. When the pressure gradually decreases, under the action of the first elastic member 324 , the end of the first air guide portion close to the second side wall 312 gradually returns to a state of contacting the second side wall 312 .

The second guide portion 3221 is parallel to the second direction along the rotation axis of the first water collecting member 322. The second guide portion 3221 passes through the second drainage hole 3222 along the first direction, so that the first water collecting member 322 is closed by the second guide portion 3221, and the impurities in the water are filtered for the second time by the second drainage hole 3222. When the amount of accumulated water is large, pressure acts on the second guide portion 3221 to make the end of the second guide portion 3221 change from a contact state with the inner wall of the first water collecting member 322 to a non-contact state, so that the accumulated water enters the first water collecting member 322.

[0033] Reference Figure 2 and Figure 4The drainage area 31 is connected to the first water collecting member 322 through the first drainage pipe 35. The first drainage pipe 35 includes a first drainage main pipe 351 and two first drainage branch pipes 352. The ends of the two first drainage branch pipes 352 are connected to the first drainage main pipe 351. One end of the first drainage main pipe 351 is located on the second guide member, one end of a first drainage branch pipe 352 is located on the first guide part 321, and the other first drainage branch pipe 352 is located on the bottom wall of the drainage area 31.

The first rack 71 is parallel to the third direction, and one end of the first rack 71 is located in the receiving groove 33, and the other end passes through the groove wall of the receiving groove 33 and extends into the drainage area 31. The end of the first rack 71 located in the drainage area 31 is fixedly connected with the first guide ball 74, and the first guide ball 74 contacts with the side of the first guide part 321 close to the second waterproof base layer 4, that is, the first guide part 321 is overlapped with the first guide ball 74, and the first rack 71 is connected to the drainage layer 3 by reciprocating sliding along the third direction; Reference Figure 5, the second rotating shaft 75 is parallel to the second direction, the second rotating shaft 75 is located in the receiving groove 33, the second rotating shaft 75 is rotatably connected to the drainage layer 3, the second rotating shaft 75 is parallel to the second direction along the rotation axis of the drainage layer 3, the first gear 72 is coaxially sleeved on the second rotating shaft 75, and the first rack 71 is meshed with the first gear 72; the second rack 73 is parallel to the third direction, one end of the second rack 73 is located in the receiving groove 33, and the other end passes through the groove wall of the receiving groove 33 and is fixedly connected to the pushing plate 6, the second rack 73 is meshed with the first gear 72, and the second rack 73 is slidably connected to the drainage layer 3 along the third direction. When pressure acts on the first guide portion 321, the first guide portion The end of 321 close to the second side wall 312 rotates toward the side away from the second side wall 312, and the bottom wall of the first guide part 321 further contacts the first guide ball 74, and pushes the first guide member to slide along the third direction toward the first side wall 311, driving the first rack 71 to slide along the first direction toward the accommodating groove 33, driving the first gear 72 to rotate, thereby driving the second rack 73 to slide along the third direction toward the side close to the drainage area 31, and driving the push plate 6 to slide along the third direction toward the second side wall 312 close to the drainage area 31, so that the push plate 6 still pushes the water tank first water collecting member 322 of the bottom wall of the drainage layer 3, thereby reducing the residual water in the drainage layer 3.

[0036] Reference Figure 5 When the pressure on the first guide portion 321 is lost, in order to restore the push plate 6 to its initial position, the anti-leakage structure of the underground garage floor without a bottom plate further includes a reset component 8, the reset component 8 is located in the receiving groove 33, the reset component 8 includes a third elastic member 81 and a mounting block 82, the mounting block 82 is fixedly connected to the first rack 71, one end of the third elastic member 81 is fixedly connected to the groove wall of the receiving groove 33, and the other end is fixedly connected to the mounting block 82.

When the pressure on the first guide portion 321 is lost, the first guide portion 321 and the first guide ball 74 change from a contact state to a non-contact state, and the first elastic member 324 gradually recovers from a stretched state to a normal state, so as to drive the first rack 71 to slide into the drainage area 31, thereby driving the push plate 6 to return to its initial position.

[0037] Reference Figure 6Since the impurities in the accumulated water will be filtered by the first water collecting member 322 and remain on the first guide part 321, the impurities may block the first drainage hole 3211 under the flushing of the accumulated water. In order to prevent the impurities from affecting the discharge of water flow, the anti-leakage structure of the bottomless floor of the underground garage also includes a cleaning plate 9, which is arranged on the first guide part 321. The cleaning plate 9 slides along the inclined direction of the first guide part 321 so that the cleaning plate 9 can scrape off the impurities on the first guide part 321, thereby reducing the blockage of the first drainage hole 3211 by impurities.

The third rack 913 is meshed with the second gear 912. When the first rack 71 slides along the third direction toward one side of the receiving groove 33, it drives the second gear 912 to rotate and drives the third rack 913 to slide toward the drainage area 31, thereby driving the cleaning plate 9 to slide along the inclined direction of the first guide part 321, and the cleaning plate 9 pushes the impurities on the first guide part 321 into the collecting groove 3214.

[0040] Reference Figure 7 Since some of the accumulated water will also enter the receiving groove 33, for this reason, the drainage component 32 also includes a second water collecting member 37, and the second water collecting member 37 is openly arranged.

The second water collecting member 37 is connected to the receiving groove 33 through the second drainage main pipe 38. One end of the second drainage main pipe 38 is located in the receiving groove 33, and the other end is located in the second water collecting member 37, so as to discharge the water in the receiving groove 33 from the second drainage pipe to the second water collecting member 37.

[0041] The implementation principle of the anti-seepage structure of the floor without a bottom plate of an underground garage in the embodiment of the present application is as follows: if the accumulated water on the concrete layer 1 enters the drainage area 31, part of the accumulated water passes through the first drainage hole 3211 and enters the bottom wall of the drainage area 31, and part of the accumulated water further enters the first water collecting member 322 through a first drainage branch pipe 352 along the inclined direction of the first guide part 321. When there is too much accumulated water, pressure acts on the first guide part 321, driving one end of the first guide part 321 to rotate in a direction away from the second side wall 312, and the first guide part 321 contacts and contacts the first guide ball 74 and the first guide ball 74 is moved to the first side wall 312. The first rack 71 is driven to slide into the receiving groove 33, and the pushing plate 6 is driven to slide toward the second side wall 312 through the first gear 72 and the second rack 73, so that the water on the bottom wall of the drainage area 31 is pushed into the first water collecting part 322. The water enters the first water collecting part 322 from another first drainage branch pipe 352 via the first drainage main pipe 351. The first rack 71 slides and drives the cleaning plate 9 to slide along the inclined direction of the first guide part 321 through the second gear 912 and the third rack 913, so that the impurities on the first guide part 321 can be pushed into the receiving groove by the cleaning plate 9.

[0042] The present application also discloses a construction process for an anti-leakage structure of a floor without a bottom plate in an underground garage, comprising the following steps: S1: pouring concrete structure layer 5: Using impermeable concrete for pouring to form a concrete structure layer 5; S2: Laying a waterproof base layer 4 on the structural layer 5 to protect the structural layer 5; S3: Install drainage layer 3: A drainage area 31 and a receiving groove 33 are provided in the drainage layer 3, a first guide portion 321 is provided in the drainage area 31, and a first driving assembly 7 and a second driving assembly 91 are installed in the receiving groove 33. If the accumulated water is small, the accumulated water enters the first water collecting member along the inclined direction of the first guide plate; if the accumulated water is large, the accumulated water enters the bottom wall of the drainage area 31 through the first drainage hole 3211 on the first guide portion 321, and the first rack 71 slides toward the receiving area to drive the push plate 6 to slide along the third direction, so as to push the water on the bottom wall of the drainage area 31 into the first water collecting member; S4: Lay the gravel layer 2 and the concrete layer 1 on the drainage layer 3.
