Description

Technical Field

[0001] The invention belongs to the technical field of building basement waterproofing, and in particular to a building basement waterproofing structure and a process thereof. Background Art

[0002] In order to maximize the use of area in modern urban buildings, basements are often built in the lower floors of buildings, which can not only increase the use area utilization rate of urban buildings but also save the backfilling step. However, because the basement is designed to be below the ground, and the basement floor and side walls cannot be cast in one piece, water from the basement side walls will enter the basement through the construction joints of the side walls, causing leakage.

[0003] In the related art, most basement corner waterproof structures use pre-laid polymer self-adhesive membrane waterproofing rolls, which may be damaged due to long-term placement and imperfect protection measures, resulting in poor waterproofing protection effects and increased risks of water seepage and leakage. They cannot meet the purpose of long-term waterproofing of building basements, making maintenance and repair difficult and costly.

[0004] Therefore, there is an urgent need for a building basement waterproof structure and process thereof, so as to solve the above-mentioned technical problems and meet the stability and reliability of long-term waterproofing of the building basement. Summary of the invention

[0005] The object of the present invention is to provide a building basement waterproof structure and a process thereof to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0006] Specifically, the first aspect of the present invention discloses a building basement waterproof structure, which is arranged in a protective wall of the basement, comprising:

[0007] A bottom plate and a side wall, wherein a first rubber asphalt layer is provided at a concave angle between the bottom plate and the side wall, wherein the upper end of the first rubber asphalt layer extends to the outer surface of the side wall, and the lower end extends to the upper surface of the bottom plate;

[0008] A first pre-laid polymer self-adhesive film waterproofing coiled material layer is disposed on the upper portion of the first rubber asphalt layer, and the first pre-laid polymer self-adhesive film waterproofing coiled material layer extends to the bottom of the base plate;

[0009] A second rubber asphalt layer is disposed on the first pre-laid polymer self-adhesive membrane waterproofing coiled material layer, and a first self-adhesive polymer modified asphalt waterproofing coiled material layer is disposed on the second rubber asphalt layer;

[0010] The upper end of the first self-adhesive polymer modified asphalt waterproofing membrane layer extends to the outer surface of the side wall, and the lower end extends to the upper surface of the bottom plate;

[0011] A second self-adhesive polymer modified asphalt waterproofing membrane layer is arranged on the upper part of the first self-adhesive polymer modified asphalt waterproofing membrane layer.

[0012] The building basement waterproof structure according to the present invention has at least the following beneficial effects:

[0013] The first rubber asphalt layer and the second rubber asphalt layer in the waterproof structure of the building basement of the present invention both adopt rubber asphalt waterproof coating, and the first rubber asphalt layer is used for base treatment, and then the first pre-laid polymer self-adhesive film waterproofing roll layer, the second rubber asphalt layer, the first self-adhesive polymer modified asphalt waterproofing roll layer and the second self-adhesive polymer modified asphalt waterproofing roll layer are laid in sequence, which can effectively avoid the damage of the reserved section of the self-adhesive film waterproofing roll due to long-term storage, and ensure the sealing of the overall long-term waterproofing effect;

[0014] The present invention extends the upper end of the first pre-laid polymer self-adhesive film waterproofing roll material layer to the upper surface of the base plate, and the upper end of the first pre-laid polymer self-adhesive film waterproofing roll material layer is located between the first rubber asphalt layer and the second rubber asphalt layer, thereby ensuring that both sides of the waterproofing roll material are completely attached to each other, thereby preventing the situation in which the waterproofing effect is affected due to the long-term placement of the reserved overlap area at the upper end of the first pre-laid polymer self-adhesive film waterproofing roll material layer and the incomplete protection measures;

[0015] The present invention adopts multiple layers of different types of waterproof materials to form multiple waterproof protections, and different types of waterproof materials can make up for each other's shortcomings, significantly improving the overall performance of the waterproof structure, reducing maintenance costs, and ensuring the waterproof durability and reliability of the building basement.

[0016] As a further solution of the present invention: sealants are respectively arranged between the second rubber asphalt layer and the first pre-laid polymer self-adhesive film waterproofing membrane layer, between the second rubber asphalt layer and the first self-adhesive polymer modified asphalt waterproofing membrane layer, and between the first self-adhesive polymer modified asphalt waterproofing membrane layer and the second self-adhesive polymer modified asphalt waterproofing membrane layer.

[0017] Since sealants are respectively arranged between the second rubber asphalt layer and the first pre-laid high molecular self-adhesive film waterproofing membrane layer, between the second rubber asphalt layer and the first self-adhesive polymer modified asphalt waterproofing membrane layer, and between the first self-adhesive polymer modified asphalt waterproofing membrane layer and the second self-adhesive polymer modified asphalt waterproofing membrane layer, the ends can be effectively sealed, thereby ensuring the overall sealing of the connection between the second rubber asphalt layer, the first pre-laid high molecular self-adhesive film waterproofing membrane layer, the first self-adhesive polymer modified asphalt waterproofing membrane layer and the second self-adhesive polymer modified asphalt waterproofing membrane layer, reducing the hidden danger of water leakage and improving the waterproof effect of the basement.

[0018] As a further solution of the present invention: the covering length between the first rubber asphalt layer and the first pre-laid polymer self-adhesive film waterproofing membrane layer, the covering length between the second rubber asphalt layer and the first self-adhesive polymer modified asphalt waterproofing membrane layer, and the covering length between the first self-adhesive polymer modified asphalt waterproofing membrane layer and the second self-adhesive polymer modified asphalt waterproofing membrane layer are 250mm-300mm respectively.

[0019] Since the covering length between the first rubber asphalt layer and the first pre-laid high molecular self-adhesive film waterproofing membrane layer, the covering length between the second rubber asphalt layer and the first self-adhesive polymer modified asphalt waterproofing membrane layer, and the covering length between the first self-adhesive polymer modified asphalt waterproofing membrane layer and the second self-adhesive polymer modified asphalt waterproofing membrane layer are 250mm-300mm respectively, there is sufficient overlapping length between the layers of waterproofing materials, which enhances the adhesion between the layers, can effectively prevent separation and delamination between the layers, ensure that the waterproof layer will not loosen or separate due to external force or environmental factors during long-term use, and ensure the overall stability of the waterproof structure.

[0020] As a further solution of the present invention: the height of the first self-adhesive polymer modified asphalt waterproof membrane layer is 250mm-300mm higher than the construction joint of the concrete structure.

[0021] Since the height of the first self-adhesive polymer modified asphalt waterproof membrane layer is 250mm-300mm higher than the construction joint of the concrete structure, it can effectively block the path of moisture penetration through the construction joint, prevent moisture from penetrating along the construction joint to the waterproof layers, enhance the sealing at the construction joint, reduce the risk of leakage at the construction joint, and ensure the long-term waterproof effect of the basement.

[0022] As a further solution of the present invention: a second pre-laid polymer self-adhesive film waterproofing membrane layer is arranged below the first pre-laid polymer self-adhesive film waterproofing membrane layer and at the inner corner on one side of the bottom plate.

[0023] By arranging a second pre-laid polymer self-adhesive film waterproof membrane layer at the lower part of the first pre-laid polymer self-adhesive film waterproof membrane layer and at the inner corner on one side of the base plate, the waterproof performance at the inner corner can be effectively enhanced, the gap between the layers can be reduced, and moisture can be prevented from penetrating through the gap in the inner corner, thereby ensuring that the waterproof layer maintains good stability and reliability during long-term use.

[0024] As a further solution of the present invention: one side of the second pre-laid polymer self-adhesive film waterproof membrane layer is bonded to the first pre-laid polymer self-adhesive film waterproof membrane layer, and the other side of the second pre-laid polymer self-adhesive film waterproof membrane layer is bonded to the protective wall of the basement.

[0025] Since one side of the second pre-laid polymer self-adhesive film waterproof membrane layer is adhered to the first pre-laid polymer self-adhesive film waterproof membrane layer, and the other side of the second pre-laid polymer self-adhesive film waterproof membrane layer is adhered to the protective wall of the basement, the second pre-laid polymer self-adhesive film waterproof membrane layer is pressed between the first pre-laid polymer self-adhesive film waterproof membrane layer and the protective wall of the basement, which can effectively enhance the adhesion between the layers, further prevent separation and delamination between the layers, reduce the gaps between the layers, prevent moisture from penetrating layer by layer through the gaps, and ensure the continuity and integrity of the waterproofing.

[0026] As a further solution of the present invention: a steel plate waterstop is arranged inside the side wall.

[0027] By installing a steel plate waterstop inside the side wall, the path for moisture to penetrate through cracks in the concrete structure or construction joints can be effectively blocked, thereby improving the side wall's anti-penetration ability, ensuring seamless coverage of the waterproof layer inside the side wall, and reducing the risk of moisture leakage.

[0028] As a further solution of the present invention: a waterproof protective layer is provided at the connection between the bottom plate and the side wall.

[0029] By setting a waterproof protective layer at the connection between the base plate and the side wall, and the first rubber asphalt layer, the first pre-laid polymer self-adhesive film waterproof roll layer, the second rubber asphalt layer, the first self-adhesive polymer modified asphalt waterproof roll layer and the second self-adhesive polymer modified asphalt waterproof roll layer are all located on the inner side of the waterproof protective layer, it can ensure that the waterproof layers between the base plate and the side wall are continuous and seamless, thereby enhancing the overall waterproof effect.

[0030] The second aspect of the present invention also discloses a building basement waterproof structure process, comprising the following steps:

[0031] S1, laying the first rubber asphalt layer along the upper surface of the bottom plate and the inner and outer corners of the side wall in a channel extending 250mm-300mm, and then laying the first pre-laid polymer self-adhesive membrane waterproofing coiled material layer on the first rubber asphalt layer and fixing it;

[0033] S3. Laying a second self-adhesive polymer modified asphalt waterproof membrane layer on top of the first self-adhesive polymer modified asphalt waterproof membrane layer.

[0034] The following steps are also included:

[0035] S01, laying a second pre-laid polymer self-adhesive film waterproofing membrane layer under the first pre-laid polymer self-adhesive film waterproofing membrane layer and at the inner corner on one side of the bottom plate;

[0036] S02. Use the sealant to seal the ends between the second rubber asphalt layer and the first pre-laid polymer self-adhesive film waterproofing membrane layer, between the second rubber asphalt layer and the first self-adhesive polymer modified asphalt waterproofing membrane layer, and between the first self-adhesive polymer modified asphalt waterproofing membrane layer and the second self-adhesive polymer modified asphalt waterproofing membrane layer for sealing treatment.

[0037] The present invention uses the process of the above-mentioned building basement waterproof structure, and through the laying and sealing of multiple layers of waterproof materials, effectively blocks the penetration of moisture through the inner corners and construction joints at the connection between the bottom plate and the side wall, ensures seamless coverage of the waterproof layer connection, and improves the continuity and integrity of the overall waterproofing; and the multi-layered waterproof material layers and the bonding therebetween enhance the stability and reliability of the overall waterproofing; at the same time, materials with good waterproof performance and durability are selected to ensure that each waterproof layer can maintain good structural stability during long-term use, reduce maintenance and repair costs, increase service life, and ensure long-term waterproofing effect of the building basement.
