[0032] Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one of ordinary skill in the art that the present application can be practiced without some or all of these specific details. The description of the embodiments is merely illustrative of the present application and is not intended to limit the present application, as is apparent to one of ordinary skill in the art. In the following description, well-known structures and techniques have not been shown in detail in order not to obscure the present application.

[0033] In the description of the present application, it should be noted that, unless otherwise specified, the meaning of "a plurality of" is more than two; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like is merely for the purpose of facilitating the description of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] The orientation words appearing in the following description are the directions shown in the drawings, and do not limit the specific structure of the embodiments of the present application. In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected. The specific meaning of the above terms in the present application can be understood by the person of ordinary skill in the art according to the specific circumstances.

[0035] In the prior art, the waterproof composite layer and the protective layer are often arranged separately, so that the waterproof composite layer and the protective layer need to be constructed at different time periods during construction, which not only affects the construction period, but also may cause the risk of peeling and falling off between the waterproof composite layer and the protective layer.

[0036] In order to solve the above problems, the waterproof drainage and protection integrated structure is provided, which integrates the waterproof composite layer and the protective layer, can reduce the risk of peeling and falling off between the waterproof composite layer and the protective layer, and at the same time improves the construction convenience and improves the construction efficiency.

[0037] Please refer to Figure 1 and Figure 2The waterproof drainage protection integrated structure 10 provided by the embodiment of the present application comprises: at least one waterproof composite layer 11, a protection layer 13 and a transition layer 12 between the waterproof composite layer 11 and the protection layer 13 which are stacked along a first direction X, the waterproof composite layer 11 comprises a self-adhesive layer 111 on the side away from the protection layer 13, and the self-adhesive layer 111 is used for bonding with the surface 20 of the building structure; the protection layer 13 comprises a plurality of concave-convex structures which are arranged in an array, and the protection layer 13 is connected with the transition layer 12 at least through the concave-convex structures and can form a plurality of airflow channels.

[0038] When the waterproof composite layer 11 and the protection layer 13 are constructed in stages, dust may exist between the waterproof composite layer 11 and the protection layer 13 due to the influence of construction conditions, which causes the bonding between the waterproof composite layer 11 and the protection layer 13 to be not firm, and arching or hollowing phenomena are prone to occur. In the waterproof drainage protection integrated structure 10 in the embodiment of the present application, the waterproof composite layer 11, the transition layer 12 and the protection layer 13 are stacked, and are integrated when leaving the factory, so that the waterproof drainage protection integrated structure 10 can be not affected by the construction site conditions, and the risk of peeling and falling off between the waterproof composite layer 11 and the protection layer 13 is reduced, thereby improving the waterproof effect, and the waterproof drainage protection integrated structure 10 can improve the construction convenience and improve the construction efficiency.

[0039] Specifically, the waterproof composite layer 11 comprises a self-adhesive layer 111 on the side away from the protection layer 13, and the self-adhesive layer 111 itself has adhesion, so that the waterproof drainage protection integrated structure 10 can be directly pasted on the required surface 20 of the building structure during use, so that the waterproof drainage protection integrated structure 10 can be attached to the surface 20 of the building structure, and reliable waterproof and protection effects of the building structure are achieved, and the operation is simple, the construction steps are reduced, thereby the construction efficiency can be significantly improved, the construction period can be effectively shortened, and the backfill soil layer 30 can be laid to complete the construction.

[0040] Exemplarily, the building structure comprises a basement side wall, a basement bottom plate, a main building skirt facade and the like.

[0041] The waterproof drainage protection integrated structure 10 in the embodiment of the present application can comprise one waterproof composite layer 11, or can comprise a plurality of waterproof composite layers 11, for example, two, three, four or more layers, and the present application is not limited thereto. When the waterproof drainage protection integrated structure 10 comprises a plurality of waterproof composite layers 11, each waterproof composite layer 11 is bonded and attached to another waterproof composite layer 11 through the self-adhesive layer 111 thereof.

[0042] Please refer to Figures 4 to 7 Among them, Figure 4 The structure diagram of the waterproof drainage protection integrated structure 10 applied to the basement side wall in the embodiment of the present application is as follows, Figure 5A construction drawing of the waterproof drainage protection integrated structure 10 applied to the main building skirt facade, Figure 6 A construction drawing of the waterproof drainage protection integrated structure 10 applied to the main building skirt facade, Figure 7 A construction drawing of the waterproof drainage protection integrated structure 10 applied to the main building skirt facade.

[0043] Please continue to refer to Figure 1 and Figure 2 The transition layer 12 is arranged between the waterproof composite layer 11 and the protection layer 13, so that the waterproof composite layer 11 and the protection layer 13 can be firmly bonded together to form a continuous whole.

[0044] The material of the transition layer 12 is not limited in the embodiments of the present application, as long as it can achieve the effect of firmly bonding the waterproof composite layer 11 and the protection layer 13 together.

[0045] In some embodiments, the transition layer 12 is a non-woven fabric adhesive layer formed by glue and non-woven fabric.

[0046] The non-woven fabric adhesive layer firmly bonds the waterproof composite layer 11 and the protection layer 13 together. The non-woven fabric itself has certain strength and flexibility, and after being compounded with glue, the glue can further enhance the mechanical properties such as tensile strength and tear strength of the non-woven fabric, so that it is less likely to be damaged when subjected to external force, and can withstand greater tension, pressure and shear force, etc.

[0047] The glue fills the pores of the non-woven fabric and the gaps between the fibers, and after solidification, it forms an effect similar to "anchoring", greatly enhancing the bonding force between the non-woven fabric and the waterproof composite layer 11 and the protection layer 13, making the connection between them more firm and reliable, and less likely to separate or fall off during use.

[0048] The protection layer 13 has a certain strength and is used to protect the waterproof composite layer 11. When laid on the building structure surface 20, the protection layer 13 is located on the side of the waterproof composite layer 11 away from the building structure surface 20, and can effectively block the impact of external force on the waterproof composite layer 11.

[0049] Further, please refer to Figures 1 to 3 The protection layer 13 includes a plurality of concave-convex structures, and the protection layer 13 is connected to the transition layer 12 at least through the concave-convex structures and can form a plurality of airflow channels. The airflow channels formed between the protection layer 13 and the transition layer 12 provide a convenient path for the flow of air, allowing air to flow freely between the protection layer 13 and the transition layer 12, which can assist in quickly draining the water vapor permeated in the underground structure, and facilitate comprehensive treatment of the basement leakage project.

[0050] The plurality of concave-convex structures are distributed in an array, which can form a structure similar to a grid or a frame, and when an external force is applied, the force can be evenly dispersed to each convex platform, thereby improving the bearing capacity and stability of the entire protective layer 13. At the same time, the concave-convex structures are distributed in an array, which is easier to use standardized processes and equipment during processing, facilitating accurate positioning and control, thereby ensuring the dimensional accuracy, shape accuracy and position accuracy of each concave-convex structure.

[0051] In summary, the waterproof drainage protection integrated structure 10 in the embodiment of the present application connects the waterproof composite layer 11 and the protective layer 13 through the transition layer 12, realizes the integration of the waterproof composite layer 11 and the protective layer 13, can reduce the risk of peeling and falling off between the waterproof composite layer 11 and the protective layer 13, at the same time, improves the construction convenience, improves the construction efficiency, and the protective layer 13 includes a plurality of concave-convex structures distributed in an array, the concave-convex structures form airflow channels, which can assist in quickly draining the water vapor permeated in the underground structure.

[0052] In some embodiments, please continue to refer to Figures 1 to 3 The concave-convex structure includes a first plane 131, a second plane 132 and a connecting portion 133 between the first plane 131 and the second plane 132, the first plane 131 is attached to the transition layer 12, the airflow channel is formed between the first plane 131 and the transition layer 12, the average area of the first plane 131 is 5cm 2 ~80cm 2 , preferably, the distribution density of the plurality of concave-convex structures in the protective layer 13 is 10~30 / m 2 .

[0053] The concave-convex structure includes a first plane 131, a second plane 132 and a connecting portion 133 between the first plane 131 and the second plane 132, wherein the first plane 131 and the second plane 132 are both arranged towards the waterproof composite layer 11. The first plane 131 is used to attach to the transition layer 12, that is, the protective layer 13 in the waterproof drainage protection integrated structure 10 is bonded together with the transition layer 12 through the first plane 131; the second plane 132 has a predetermined interval with the transition layer 12 to form an airflow channel between the second plane 132 and the transition layer 12. The connecting portion 133 is arranged between the first plane 131 and the second plane 132 and connected with the first plane 131 and the second plane 132 respectively, and the connecting portion 133 can support the first plane 131.

[0054] The concave-convex structure is arranged in an array, and the first planes 131 are arranged in an array, that is, the first planes 131 are discontinuous. In order to improve the bonding strength between the protective layer 13 and the transition layer 12, the single first plane 131 needs to have a certain area. The larger the area of the first plane 131, the larger the area of the first plane 131 and the transition layer 12, and the peel strength is also improved accordingly. However, if the area of the first plane 131 is too large, the size of the airflow channel will be compressed. After comprehensive consideration, the average area of the first plane 131 in the embodiment of the application is 0.5 cm 2 ~ 64 cm 2 The average area of the first plane 131 is in the above range, which can make the first plane 131 and the transition layer 12 have a suitable bonding area, and can make the airflow channel have a suitable size for water vapor dissipation. For example, the average area of the first plane 131 is 0.5 cm 2 , 0.1 cm 2 , 2 cm 2 , 3 cm 2 , 4 cm 2 , 5 cm 2 , 10 cm 2 , 15 cm 2 , 20 cm 2 , 25 cm 2 , 30 cm 2 , 35 cm 2 , 40 cm 2 , 45 cm 2 , 50 cm 2 , 55 cm 2 , 60 cm 2 , 65 cm 2 , 70 cm 2 , 75 cm 2 , or 80 cm 2 .

[0055] The areas of the plurality of first planes 131 can be the same. When the areas of the plurality of first planes 131 are the same, it is convenient to use standardized processes and equipment, and it is convenient to accurately position and control. The areas of the plurality of first planes 131 can also be different. For example, the sizes of the first planes 131 along the first straight line are the same, the sizes of the first planes 131 along the second straight line are also the same and uniform, the first straight line is parallel to the second straight line, but the sizes of the first planes 131 along the first straight line are different from the sizes of the first planes 131 along the second straight line. The application is not limited thereto.

[0056] The shape of the first plane 131 can be various, such as a square, a circle, etc., and the application is not limited thereto.

[0057] Exemplarily, the first plane 131 is circular in shape, and the diameter can be 1 cm to 9 cm. When the diameter is 1 cm, the area of the first plane 131 is 0.785 cm 2 When the diameter is 9 cm, the area of the first plane 131 is 63.585 cm 2 .

[0058] The impact resistance and the water vapor dissipation effect of the waterproof and drainage protection integrated structure 10 are related to the distribution density of the concave-convex structure in the protection layer 13. When the average area of the first plane 131 is determined, the greater the distribution density of the concave-convex structure, the stronger the impact resistance, but the ventilation effect will be weakened. After comprehensive consideration, the distribution density of the concave-convex structure in the protection layer 13 is 50 to 1800 / m 2 . The distribution density of the concave-convex structure in the above range can make the waterproof and drainage protection integrated structure 10 have good impact resistance and water vapor dissipation effect. Exemplarily, the distribution density of the concave-convex structure in the protection layer 13 is 50 / m 2 , 60 / m 2 , 70 / m 2 , 80 / m 2 , 90 / m 2 , 100 / m 2 , 200 / m 2 , 300 / m 2 , 400 / m 2 , 500 / m 2 , 600 / m 2 , 700 / m 2 , 800 / m 2 , 900 / m 2 , 1000 / m 2 , 1100 / m 2 , 1200 / m 2 , 1300 / m 2 , 1400 / m 2 , 1500 / m 2 , 1600 / m 2 , 1700 / m 2 , or 1800 / m 2 .

[0059] At the same time, the impact resistance of the waterproof and drainage protection integrated structure 10 is also related to the extension direction of the connecting part 133. In some embodiments, please refer to Figure 3The extension direction of the connecting portion 133 intersects the first direction X. The extension direction of the connecting portion 133 intersecting the first direction X can keep the connecting portion 133 in an inclined state between the first plane 131 and the second plane 132. The inclined connecting portion 133 can form a more stable triangular structure with the first plane 131 and the second plane 132. The stability principle of the triangle makes this structure better resist external forces, reduces shaking and deformation, and thus enhances the overall stability.

[0060] The extension direction of the connecting portion 133 in the embodiments of the present application can also be parallel to the first direction X, and the present application is not limited thereto.

[0061] To achieve the protection of the protection layer 13, in some embodiments, the compression resistance of the protection layer 13 is ≥90kPa, and the elongation at break is ≥20%.

[0062] The compression resistance and elongation at break of the protection layer 13 meet the above requirements, which can make the protection layer 13 have good impact resistance, so that the waterproof and drainage protection integrated structure 10 has good strength.

[0063] Exemplarily, the protection layer 13 can use a high-density polyethylene plate as a protection plate.

[0064] The high-density polyethylene plate has a compact molecular structure, extremely low water absorption, and good water vapor resistance, which can effectively prevent water from penetrating from the external environment to the inside of the protected structure. Whether it is rainwater, groundwater or other water sources, it is difficult to penetrate through the plate, thereby providing a reliable defense line for the waterproof structure and ensuring that the inside of the structure remains dry.

[0065] At the same time, the high-density polyethylene plate has high strength and toughness, excellent physical puncture resistance, and can withstand certain external force impact without being easily damaged. When an object hits or presses the waterproof and drainage protection integrated structure 10, the high-density polyethylene plate can play a buffering role to protect the integrity of the internal structure and can assist in avoiding the penetration and damage of the plant root system to the bottom waterproof composite layer 11 and the structure layer, thereby reducing the risk of later water leakage.

[0066] In addition, high-density polyethylene is a non-toxic, odorless, and pollution-free environmentally friendly material, which has less impact on the environment during production, use, and disposal, and meets the development requirements of modern green buildings.

[0067] The protection layer 13 can also use other hard boards that meet the requirements as protection plates, and the present application is not limited thereto.

[0068] In some embodiments, please refer to Figure 1The waterproof composite layer 11 is one layer, and the waterproof composite layer 11 comprises a first adhesive layer and a first polymer film layer 112 arranged in layers. The first adhesive layer is located on the side of the first polymer film layer 112 away from the transition layer 12. The first polymer film layer 112 is bonded to the transition layer 12. The first adhesive layer serves as a self-adhesive layer 111.

[0069] The one-layer waterproof composite layer 11 is relatively simple and fast to process, reduces production procedures and time, and improves production efficiency. At the same time, due to the small number of layers, the probability of quality problems such as interlayer hollowing and peeling during production is also reduced. Compared with the multi-layer waterproof composite layer 11, the one-layer waterproof composite layer 11 is relatively low in material cost and construction cost.

[0070] In some embodiments, referring to Figure 2 The waterproof composite layer 11 is two layers, and the waterproof composite layer 11 comprises a first waterproof composite layer A and a second waterproof composite layer B arranged in layers. The first waterproof composite layer A comprises a first adhesive layer and a first polymer film layer 112 arranged in layers. The first adhesive layer is located on the side of the first polymer film layer 112 away from the transition layer 12. The second waterproof composite layer B is located between the first waterproof composite layer A and the transition layer 12. The second waterproof composite layer B comprises a second adhesive layer 113 and a second polymer film layer 114. The second adhesive layer 113 is bonded to the first polymer film layer 112. The second polymer film layer 114 is bonded to the transition layer 12. The first adhesive layer serves as a self-adhesive layer 111.

[0071] The first waterproof composite layer A and the second waterproof composite layer B are arranged in layers and cooperate with each other, which can more effectively resist the penetration of water and reduce the probability of leakage, greatly enhancing the reliability and safety of waterproofing and providing more durable and stable protection for building structures. The waterproof and drainage protection integrated structure 10 with the first waterproof composite layer A and the second waterproof composite layer B is especially suitable for some projects with high waterproofing requirements, such as large commercial buildings, hospitals, airports, etc.

[0072] In addition, the two-layer waterproof composite layer 11 can increase the construction fault tolerance: if local defects occur in the construction of a layer of waterproof composite layer 11, the other layer of waterproof composite layer 11 can still play a certain waterproofing role, reducing the risk of leakage due to construction quality problems, and also providing a certain fault tolerance space for construction personnel, improving the stability of the overall construction quality.

[0073] In some embodiments, the thickness d of each waterproof composite layer 11 satisfies d≥1.5mm.

[0074] The thickness of each waterproof composite layer 11 in the waterproof and drainage protection integrated structure 10 of the embodiments of the present application reaches or exceeds 1.5 mm, which can increase the path length and resistance of water penetration, making it difficult for liquid water to penetrate, thereby forming a reliable waterproof barrier and reducing the risk of leakage.

[0075] At the same time, a certain thickness can make the waterproof composite layer 11 have better mechanical properties, and it is less likely to be punctured or torn when subjected to external force, thereby ensuring the integrity of the waterproof composite layer 11.

[0076] In some scenarios, the waterproof and drainage protection integrated structure 10 is put into use soon after production, for example, produced on site and directly put into use after production, at which time the waterproof and drainage protection integrated structure 10 includes at least one waterproof composite layer 11, a protection layer 13, and a transition layer 12 between the waterproof composite layer 11 and the protection layer 13.

[0077] In other scenarios, the waterproof and drainage protection integrated structure 10 exists in a coiled state, and the waterproof and drainage protection integrated structure 10 can also include at least one waterproof composite layer 11, a protection layer 13, and a transition layer 12 between the waterproof composite layer 11 and the protection layer 13.

[0078] In yet other scenarios, the production and construction of the waterproof and drainage protection integrated structure are not in the same place, and the waterproof and drainage protection integrated structure needs to be transported from the production place to the construction place, at which time the waterproof and drainage protection integrated structure 10 needs to be protected. Therefore, in some embodiments, referring to Figure 1 and Figure 2 , the waterproof and drainage protection integrated structure 10 further includes an isolation film 14, and the self-adhesive layer 111 is covered by the isolation film 14.

[0079] The isolation film 14 is arranged on the side surface of the self-adhesive layer 111 away from the high polymer film layer, the isolation film 14 covers the self-adhesive layer 111, and the isolation film 14 can keep the waterproof and drainage protection integrated structure 10 in a good isolation state before paving, preventing the waterproof and drainage protection integrated structure 10 from being contaminated, damp, and adhered during storage and transportation, maintaining the performance and quality stability of the waterproof and drainage protection integrated structure 10, and ensuring normal use during construction. The construction personnel can expose the self-adhesive layer 111 by removing the isolation film 14 when needed, and then pave.

[0080] In some embodiments, referring to Figures 8 to 11 , the waterproof composite layer 11 has a functional part 115 and a lap joint part 116 surrounding the functional part 115, the functional part 115 is flush with the edge of the protection layer 13, and the lap joint part 116 protrudes from the edge of the protection layer 13.

[0081] The waterproof composite layer 11 in the embodiment of the present application includes a lap joint part 116, which is used to realize the lap joint of adjacent waterproof and drainage protection integrated structures 10. When the lap joint is performed, the protection layers 13 of the adjacent waterproof and drainage protection integrated structures 10 are connected, and the lap joint parts 116 of the adjacent waterproof and drainage protection integrated structures 10 are overlapped together, so that the lap joint is reliable, and the construction quality of the waterproof composite layer 11 is effectively ensured.

[0082] The adjacent waterproof and drainage protection integrated structures 10 are tightly connected through the lap joint parts 116, forming a continuous whole waterproof composite layer 11, which avoids the penetration of water due to the gaps between the waterproof and drainage protection integrated structures 10, thereby effectively preventing rainwater, groundwater and the like from entering the inside of the building and reducing the risk of leakage.

[0083] In addition, the lap joint part 116 connects and restricts the adjacent waterproof and drainage protection integrated structures 10, thereby enhancing the stability of the whole waterproof composite layer 11, so that the whole waterproof composite layer 11 can maintain good integrity when subjected to external force, and is not prone to displacement, warping, tearing and the like.

[0084] The lap joint part 116 can completely surround the functional part 115, i.e., the lap joint part 116 is arranged around the functional part 115, so that the waterproof and drainage protection integrated structures 10 can be lap jointed on each side. The lap joint part 116 can also partially surround the functional part 115, i.e., the lap joint part 116 is arranged on only part of the side of the functional part 115, which is used for directional lap joint of the waterproof and drainage protection integrated structures 10.

[0085] For example, when the number of layers of the waterproof composite layer 11 is one layer, referring to Figure 8 , the corresponding area of the waterproof composite layer 11 and the protection layer 13 is the functional part 115, the corresponding area of the waterproof composite layer 11 and the protection layer 13 is the functional part 115, which is used to realize the main waterproof function, the area protruding from the edge of the protection layer 13 is the lap joint part 116, which is used for the lap joint of the adjacent waterproof and drainage protection integrated structures 10. When the isolation film 14 exists, the isolation film 14 covers the whole layer of the waterproof composite layer 11.

[0086] The waterproof and drainage protection integrated structure 10 is provided with the lap joint part 116 on both sides of the functional part 115 Figure 8 , only one side of which is provided with the lap joint part 116), when the adjacent two waterproof and drainage protection integrated structures 10 are lap jointed, referring to Figure 9 , the respective lap joint parts 116 can be overlapped and laid, and the functional parts 115 are placed side by side.

[0087] For example, when the number of layers of the waterproof composite layer 11 is two layers, referring to Figure 10, waterproof drainage protection integrated structure 10 is provided with a lap joint part 116 on one side of the functional part 115 of one waterproof composite layer, and the edges of the two waterproof composite layers on the other side are flush with the edges of the protection layer 13, for example, the lap joint part 116 is provided on one side of the functional part 115 of the second waterproof composite layer B, and the lap joint part 116 is provided on one side of the functional part 115 of the second waterproof composite layer B, which is beneficial to improve the flatness during laying. When the isolation film 14 exists, the isolation film 14 covers the entire first waterproof composite layer A, the second waterproof composite layer B, the area protruding from the edge of the protection layer 13, and the area between the edges of the first waterproof composite layer A and the second waterproof composite layer B that need to be engaged.

[0088] In the embodiments of the present application, when the number of layers of the waterproof composite layer 11 is two, the lap joint part 116 can also be provided on one side of the functional part 115 of the first waterproof composite layer A, and the present application is not limited thereto.

[0089] When the waterproof drainage protection integrated structure 10 is lapped, please refer to Figure 11 The protruding lap joint part 116 can be inserted between the two waterproof composite layers of the adjacent waterproof drainage protection integrated structure 10 for engagement and lap joint, and the functional parts 115 are placed side by side.

[0090] The width of the lap joint part 116 is not specifically limited in the embodiments of the present application, and can be set as needed, and exemplarily, the width of the lap joint part 116 protruding from the edge of the protection layer 13 is 80-100mm.

[0091] The width of the lap joint part 116 protruding from the edge of the protection layer 13 is 80-100mm, which can ensure the close connection between the adjacent waterproof drainage protection integrated structures 10, effectively prevent water from seeping from the lap joint part, improve the overall sealing performance and waterproof effect of the waterproof composite layer 11, the service life, and protect the waterproof function of the building.

[0092] Although the present application has been described with reference to the preferred embodiments, various modifications can be made thereto and equivalents can be substituted for elements thereof without departing from the scope of the present application. In particular, the technical features mentioned in each embodiment can be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
