Description

Technical Field

[0001] The utility model belongs to the technical field of basement waterproof construction, and in particular relates to an anti-floating structure of a basement bottom plate. Background Art

[0002] With the rapid development of urban construction, the utilization of underground space is gaining increasing attention. When constructing underground structures such as basements in areas with high groundwater levels, it is often necessary to first install anti-floating anchor bolts to prevent the buoyancy of the groundwater from lifting the entire basement and causing structural damage.

[0003] When constructing an anti-floating anchor rod structure, the bottom end of the anti-floating anchor rod must be driven into the ground and anchored first. When constructing the basement floor slab later, the top end of the anti-floating anchor rod must be anchored into the basement floor slab. This way, after the basement is poured, the anti-floating anchor rod can be used to limit the overall floating caused by the buoyancy of groundwater.

[0004] In order to reduce the subsequent infiltration of groundwater into the basement through the basement floor, a waterproof structural layer is usually provided at the bottom of the basement floor. However, since the anti-floating anchor rods need to be passed through the waterproof structural layer, a seepage channel is easily formed in the gap between the anti-floating anchor rods and the waterproof structural layer. Subsequent groundwater can penetrate into the basement floor through the seepage channel between the waterproof structural layer and the anti-floating anchor rods and finally penetrate into the basement.

[0005] Prior art, such as the document with authorization announcement number CN218204545U, discloses a new anti-floating and anti-leakage structure for a basement floor, comprising a floor, an anchor assembly connected to the floor and passing through the bottom into the soil, a guide cap connected to the bottom of the anchor assembly, a bladder connected to the lower part of the anchor assembly and adjacent to the guide cap, a cage core connected between the bladder and the anchor assembly and filling material in the bag, and bent ribs connected to the top of the anchor assembly.

[0006] However, this device still has the following problems: the number of structural elements installed on the anchor rod and the number of materials used for the elements are too large, which not only makes installation difficult and construction inconvenient, but also has high costs.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0030] The utility model provides an anti-floating structure of a basement floor, comprising a floor 11, an anchor rod assembly 12 connected to the floor 11 and entering into a soil body a, a leveling layer 1, a waterproof structure layer 2, and a waterproof reinforcement layer 3 are sequentially arranged along the direction from the soil body a to the floor 11, and a reinforced waterproof pipe 4 is arranged outside the anchor rod assembly 12, which is located in the waterproof structure layer 2 and passes through the leveling layer 1 to enter into the soil body a.

[0031] It is worth noting that the bottom end of the anchor assembly 12 is anchored within the soil a, while the top end of the anchor assembly 12 penetrates the leveling layer 1, the waterproof structural layer 2, and the waterproof reinforcement layer 3 and is anchored into the base plate 11. A reinforced waterproof pipe 4 is coaxially sleeved outside the anchor assembly 12. The bottom end of the reinforced waterproof pipe 4 enters the soil a, while the top end of the reinforced waterproof pipe 4 passes through the leveling layer 1 and enters the waterproof structural layer 2. Preferably, the top end of the reinforced waterproof pipe 4 is flush with the upper surface of the waterproof structural layer 2. The reinforced waterproof pipe 4 is filled with uncured rubber asphalt or waterproof concrete.

[0032] In this embodiment, the leveling layer 1 is cast from mortar and has an overall thickness of approximately 50 mm. The waterproof structural layer 2 includes a concrete layer 201 connected to the leveling layer 1 and reinforcing steel bars 202 embedded within the concrete layer 201. The concrete layer 201 is cast from impermeable concrete and has an overall thickness of approximately 120 mm. The reinforcing steel bars 202 are arranged in a mesh pattern within the concrete layer 201 to strengthen the overall strength of the structural layer and prevent cracking. The reinforcing steel bars 202 closest to the reinforced waterproof pipe 4 can be directly welded to the pipe wall to enhance the support and position-limiting effect of the reinforced waterproof pipe 4.

[0033] In this embodiment, the waterproof reinforcement layer 3 includes a reinforcement layer 301 connected to the concrete layer 201, a waterproof roll layer 302 disposed on an end of the reinforcement layer 301 away from the concrete layer 201, a connection hole 303 disposed on the waterproof roll layer 302, a fixing ring 304 disposed within the connection hole 303 and connected to the anchor assembly 12, and a connection layer 305 disposed on the waterproof roll layer 302 and connected to the base plate 11. The reinforcement layer 301 is formed of a waterproof coating, which may be a cement-based permeable crystalline waterproof coating having a thickness of approximately 40 mm. The waterproof roll layer 302 extends upward along the anchor assembly 12 near the connection hole 303 and is fixedly wrapped around the outer periphery of the anchor assembly 12 by the fixing ring 304. The fixing ring 304 and the anchor assembly 12, as well as the roll layer and the anchor assembly 12, are bonded and fixed by a sealant, which may be a polyurethane sealant. The connection layer 305 is cast from impermeable concrete and may be 60 mm thick, which helps prevent groundwater from directly seeping into the bottom plate 11 after the coiled material layer is damaged.

[0034] In this embodiment, the reinforced waterproof pipe 4 includes a sleeve body 401, a conical tube 402 arranged at the end of the sleeve body 401 and entering the soil a, a first fixed ring plate 403 arranged on the outer periphery of the sleeve body 401 near the conical tube 402, a second fixed ring plate 404 arranged on the outer periphery of the sleeve body 401, and an expansion waterstop 405 arranged between the first fixed ring plate 403 and the second fixed ring plate 404.

[0035] It is worth noting that the tapered tube 402 is a tube with a gradually decreasing outer diameter from top to bottom. The tapered tube 402 is connected to the sleeve body 401, and the inner wall of the tapered tube 402 is in contact with the outer periphery of the anchor assembly 12. The tapered tube 402 is used to reduce the difficulty of inserting the entire reinforced waterproof tube 4 into the soil a, ensuring the connection strength between the reinforced waterproof tube 4 and the soil a. The upper end of the tapered tube 402 is flush with the soil a, and the first fixed ring plate 403 is in contact with the surface of the soil a, improving the watertight seal between the soil a and the leveling layer 1. The second fixed ring plate 404 is located at the connection between the leveling layer 1 and the concrete layer 201, and preferably, the second fixed ring plate 404 is in contact with the upper surface of the leveling layer 1 to improve the watertight seal between the leveling layer 1 and the concrete layer 201. The expansion waterstop 405 is limited by the first fixed ring plate 403 and the second fixed ring plate 404, so that the expansion waterstop 405 is not easily separated from the casing body 401. The expansion waterstop 405 expands when exposed to water, further sealing the gap between the casing body 401 and the leveling layer 1, improving the water-stopping seal and limiting the upward infiltration of groundwater through the gap between the casing body 401 and the leveling layer 1. Preferably, the length of the second fixed ring plate 404 is greater than that of the first fixed ring plate 403, further improving the water-stopping effect.

[0036] As a further preferred embodiment of this embodiment, the reinforced waterproof tube 4 further comprises a third fixing ring plate 406 disposed on the outer periphery of the end of the casing body 401 away from the tapered tube 402. The third fixing ring plate 406 is located near the upper surface of the concrete layer 201 on the casing body 401 and is used to enhance the sealing and water-stopping effect between the casing body 401 and the concrete layer 201.

[0037] As a further preferred embodiment of this embodiment, the reinforced waterproof tube 4 further includes an opening 407 provided on the outer periphery of the casing body 401 between the second fixing ring plate 404 and the third fixing ring plate 406 and communicating with the interior of the casing body 401. The provision of the opening 407 facilitates the concrete poured into the tube to flow out of the tube body through the opening 407, thereby ensuring the pouring effect between the second fixing ring plate 404 and the third fixing ring plate 406, avoiding the problem of concrete not being able to completely fill the space between the second fixing ring plate 404 and the third fixing ring plate 406 due to obstruction, further promoting the integration of the casing body 401 and the concrete layer 201, reducing the number of gaps, and improving the water-stopping and sealing effect.

[0038] As a further preferred embodiment of this embodiment, the reinforced waterproof tube 4 further includes a mounting screw groove 408 provided on the surface of the third fixing ring plate 406, an external screw 409 threadedly connected to the mounting screw groove 408, and a handle 410 provided on the external screw 409. This configuration is intended to allow the sleeve body 401 to rotate the conical tube 402 before the conical tube 402 enters the soil a, thereby clearing the soil at the front end of the conical tube 402, facilitating the entry of the conical tube 402 into the soil a and improving construction efficiency. After the conical tube 402 is installed, the handle 410 can be removed and recycled for future use.

[0039] As a further preferred embodiment of this embodiment, the reinforced waterproof tube 4 further includes a ball bearing 411 disposed on the inner tube wall of the end of the tapered tube 402 and connected to the anchor assembly 12. The provision of the ball bearing 411 not only reduces the frictional resistance between the tapered tube 402 and the anchor assembly 12, but also helps improve the sealing between the tapered tube 402 and the anchor assembly 12.

[0040] The implementation principle of this embodiment includes the following steps: first, installing the reinforced waterproof pipe 4 on the anchor rod assembly 12, rotating the reinforced waterproof pipe 4 until the tapered pipe 402 is drilled into the soil a and the first fixed ring plate 403 is in contact with the surface of the soil a; second, installing the expansion waterstop 405; third, pouring the leveling layer 1 until the upper surface of the leveling layer 1 is in contact with the lower surface of the second fixed ring plate 404; fourth, tying the reinforcing steel bars 202 on the leveling layer 1 and welding the reinforcing steel bars 202 close to the casing body 401 to the outer periphery of the pipe body; fifth, pouring concrete into the pipe body and on the leveling layer 1 until the concrete is flush with the upper end of the casing body 401 to form a concrete layer 201; sixth, applying waterproof material on the concrete layer 201 to form a reinforcement layer 301, and then laying SBS waterproof membrane on the reinforcement layer 301 to form a waterproof membrane layer 302; seventh, pouring concrete on the waterproof membrane layer 302 to form a connecting layer 305; finally, pouring the basement floor 11.

[0041] Compared to existing technologies, the anti-floating structure provided by this embodiment utilizes an integrated pipe body, which not only improves the sealing and watertightness between layers, but also between the pipe body itself and the layers. Furthermore, the integrated pipe body is simple to construct and can also serve as a guide for pouring each construction layer, offering the advantages of simple operation and high construction efficiency.

[0042] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
