Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a waterproof structure for an entrance garden and its construction process. Background Technology

[0002] As people's demands for the quality of their living environment continue to rise, entrance gardens, as transitional spaces connecting the outdoors and indoors, have become a common feature in modern residential design. Entrance gardens are usually in direct contact with the outdoors and often involve planting greenery and small water features. They are constantly facing problems such as rainwater seepage and water accumulation. If waterproofing is not done properly, it can easily lead to floor leaks, which can not only damage interior decoration and affect the living experience, but may also pose a threat to the structural safety of the building. Therefore, the waterproofing performance of entrance gardens is of paramount importance.

[0003] Currently, waterproofing of entrance gardens in residential buildings mostly adopts traditional methods, mainly divided into two categories: flexible waterproofing and rigid waterproofing. Flexible waterproofing often uses rolled materials or coatings, which have a certain degree of flexibility and crack resistance. However, gaps can easily appear at the joints of rolled materials due to improper construction. Coatings, on the other hand, suffer from uneven application thickness and insufficient adhesion to the substrate. After long-term use, they are susceptible to aging and cracking due to factors such as ultraviolet rays and temperature changes, leading to waterproofing failure. Rigid waterproofing mostly uses ordinary cement mortar, which has high strength and good durability, but poor flexibility. When the building structure develops tiny cracks due to settlement or temperature deformation, the waterproofing layer is prone to cracking as well, losing its waterproofing function.

[0004] Furthermore, existing waterproofing construction techniques are insufficient in treating details such as pipe penetrations through floor slabs, corners, and around floor drains. They often use the same materials and construction methods as the main waterproofing layer, without specifically reinforcing these leak-prone areas. Additionally, some construction processes lack standardized control, such as incomplete base treatment and improper water retention tests after waterproofing layer construction, further increasing the risk of leaks in the entrance garden.

[0005] To address the problems of easy leakage, poor durability, and insufficient treatment of details in existing waterproofing technologies for entrance gardens, there is an urgent need for an entrance garden waterproofing structure and its construction process that is structurally reasonable, has standardized construction techniques, reliable waterproofing effect, and can adapt to minor building deformations. Therefore, this paper provides an entrance garden waterproofing structure and its construction process. Summary of the Invention

[0006] The purpose of this application is to provide a waterproof structure for an entrance garden and its construction process to solve the problems existing in the background art.

[0007] This application provides a waterproof structure for an entrance garden, employing the following technical solution: It includes a base structure layer, a detailed supplementary layer, a rigid waterproof layer, and a water-blocking mechanism. The base structure layer is a floor slab structure with a surface free of dust, debris, and defects such as hollow areas and cracks. The corners and pipe roots of the base structure layer are all rounded or obtuse angles. The detailed supplementary layer is laid around the pipe roots, drains, and corners of the base structure layer. The rigid waterproof layer completely covers the surfaces of the base structure layer and the detailed supplementary layer. The water-blocking mechanism is located at the entrance of the entrance garden. The detailed supplementary layer is made of waterproof coating, which is evenly applied around the pipe roots, drains, and corners. The rigid waterproof layer is made of polymer waterproof mortar, which is mixed evenly according to a preset ratio and then laid on the surfaces of the base structure layer and the detailed supplementary layer. The water-blocking mechanism is a water-blocking sill formed by pouring cement mortar, which is tightly bonded to the base structure layer. By adopting the above technical solutions, the requirements for the base structure layer are clearly defined as "free from dust, debris, hollow areas, and cracks" and "corners and pipe roots should be rounded or obtuse." This avoids impurities in the base layer causing insufficient adhesion of the waterproof layer or sharp edges that could damage the waterproof layer. It provides a smooth and defect-free foundation for subsequent waterproof structures, reducing the risk of waterproof layer damage from the source. Detailed additional layers are precisely placed at easily leaking nodes such as pipe roots, floor drains, and corners, specifically strengthening waterproofing in weak areas. Simultaneously, the rigid waterproof layer completely covers both the base layer and the detailed additional layers, forming a double-layer waterproof structure of "specific node protection + overall comprehensive protection." This solves localized leakage problems while ensuring overall waterproofing effectiveness. The water-blocking mechanism uses a water-blocking sill that is tightly integrated with the base layer. This stably blocks water flow during water storage tests, preventing test water from overflowing and ensuring the tests can be carried out normally. This accurately detects whether there are leaks in the waterproof structure, ensuring the quality of waterproof construction meets standards. The overall structure is complete and provides comprehensive protection for the entrance garden waterproofing system.

[0008] Preferably, the waterproof coating is an elastic flexible waterproof coating, and during the application process, it is applied in a ring around the pipe root and the drain, and continuously applied along the inside and outside corners. By adopting the above technical solutions, the waterproof coating is defined as an "elastic flexible waterproof coating." Its elastic properties can adapt to the slight deformation of the building caused by settlement and temperature changes, avoiding cracking of the coating due to structural deformation and solving the problem of easy cracking and failure of traditional rigid coatings. The process of "circular wrapping of the pipe roots and floor drains, and continuous coating of the inside and outside corners" is specified, which allows the waterproof coating to completely conform to the outline of the node without any blind spots. At the same time, it is required to be "free of bubbles and free of missed areas" to avoid gaps caused by improper coating. This further enhances the sealing and waterproofing performance of key nodes such as pipe roots, floor drains, and inside and outside corners, and reduces the probability of leakage at the nodes.

[0009] Preferably, before laying the polymer waterproof mortar, the surface of the base structure layer and the detailed additional layer is cleaned and moistened. During laying, a troweling process is used to ensure that the mortar adheres tightly to the base layer. After laying, the surface of the rigid waterproof layer is polished. By adopting the above technical solutions, the surface of the base layer and detailed additional layer is "cleaned and moistened" before laying the polymer waterproof mortar. This removes surface dust and impurities, while keeping the base layer moderately moist to prevent the mortar from being absorbed too quickly by the base layer, which could lead to shrinkage and cracking. It also enhances the adhesion between the mortar and the base layer, preventing hollow areas between the mortar and the base layer. The "troweling process" used during laying removes air from the mortar, allowing it to adhere tightly to the base layer and detailed additional layer, reducing internal gaps. The "smoothing treatment" after laying fills the tiny pores on the mortar surface, improving the density of the rigid waterproof layer and thus enhancing its impermeability. This solves the problem of poor impermeability caused by the high porosity and low density of traditional rigid waterproof layers.

[0010] Preferably, the water-retaining sill is integrally connected with the wall or ground structure at the entrance of the entrance garden during the pouring process, the surface of the water-retaining sill facing the inside of the entrance garden is smoothed, and the top end face of the water-retaining sill is finished and compacted. By adopting the above technical solutions, the water-retaining sill is "integrated with the doorway wall or ground structure" during pouring, which avoids gaps between the water-retaining sill and the surrounding structure, prevents test water from leaking out from the joint, and solves the problem of test water leakage caused by loose joints in traditional water-retaining structures. The "smoothing treatment" of the inner surface of the water-retaining sill and the "smoothing and compaction treatment" of the top end face can eliminate surface roughness, protrusions or loose particles, avoid the waterproof layer being scratched by rough edges and corners, or water seepage due to loose end faces, ensure that the water-retaining sill itself has no leakage risk, provide reliable water-retaining protection for water storage tests, and ensure accurate test results.

[0011] A waterproofing construction process for an entrance garden includes the following steps: Preferably, the construction process is as follows: Step 1, construction preparation, including technical preparation, material preparation, construction equipment preparation, construction personnel preparation, and inspection of working conditions; Step 2, base treatment, cleaning and leveling the surface of the base structure layer, and treating the corners and pipe roots; Step 3, detailed additional layer construction, applying waterproof coating around the pipe roots, drains, and corners of the base structure layer to form a detailed additional layer; Step 4, rigid waterproof layer construction, laying polymer waterproof mortar on the surface of the base structure layer and detailed additional layer to form a rigid waterproof layer; Step 5, water retention test, blocking water flow through a water-blocking mechanism, releasing water onto the surface of the rigid waterproof layer for water retention testing, and completing the construction after confirming no leakage. By adopting the above technical solutions, a complete process of "construction preparation → base treatment → detailed additional layer construction → rigid waterproof layer construction → water retention test" is established, providing clear step-by-step guidance for waterproofing construction and avoiding construction chaos. Each step is interconnected: construction preparation lays the foundation for subsequent construction, base treatment ensures the adhesion of the waterproof layer, detailed additional layers and rigid waterproof layers address node and overall protection respectively, and the water retention test verifies the final quality, forming a standardized construction system. This can reduce waterproofing defects caused by disordered construction sequence or missing steps, improve construction standardization, and ensure stable and consistent waterproofing effects.

[0012] Preferably, the technical preparation in step one includes reviewing construction drawings and design change documents, mastering relevant waterproofing specifications and technical standards, understanding the performance and operation process of waterproofing materials, preparing a waterproofing construction plan, and providing written technical instructions to construction personnel; material preparation requires ensuring that materials such as polymer waterproof mortar and waterproof coatings have factory certificates of conformity and quality inspection reports, and witness sampling and re-inspection are carried out according to specifications, and they can only be used after passing the re-inspection; construction equipment preparation includes preparing plastic containers, scrapers, brushes, trowels, putty knives, brooms, and fire-fighting equipment; construction personnel must have the corresponding qualifications, have undergone professional training, and be certified to work; the inspection of working conditions requires confirming that pipes penetrating the floor slab and floor drains are firmly installed and have passed acceptance, and that pipe holes and reserved openings have been sealed tightly with fine stone concrete; By adopting the above technical solutions, the technical preparation process, including "reviewing drawings, mastering specifications, preparing plans, and providing technical briefings," ensures that construction personnel clearly understand the design requirements and operating standards, avoiding construction errors due to misunderstandings. The material preparation requirement of "materials having certificates of conformity, test reports, and passing re-inspection" eliminates the use of substandard materials, ensuring waterproofing performance from the source and preventing waterproofing failure due to poor material quality. The complete preparation of construction equipment and tools ensures smooth construction and avoids impacts on efficiency or quality due to missing equipment. The requirement that construction workers "possess qualifications, undergo professional training, and hold certificates" ensures standardized operation and reduces waterproofing problems caused by improper operation. The work condition inspection, including "confirming that pipes are securely installed and openings are tightly sealed," prevents leakage caused by loose pipes or unsealed openings during subsequent construction, creating a qualified working environment for waterproofing construction and comprehensively managing construction risks in advance.

[0013] Preferably, in step two, the base treatment requires first removing dust, debris, hardened mortar lumps and protruding parts from the surface of the base structure layer, and then leveling the surface to ensure that the base surface is clean and flat; for inside and outside corners and pipe roots, cement mortar should be used to make rounded or obtuse angles to ensure a smooth transition; By adopting the above technical solutions, the first step in the base treatment is to "remove dust, debris, hardened mortar lumps, and protruding parts," which removes obstacles on the base surface that affect the adhesion of the waterproof layer and prevents hollowing and detachment of the waterproof layer due to impurities. The "leveling treatment" of the base surface ensures a smooth surface, preventing damage to the waterproof layer due to uneven stress caused by uneven base surfaces. The corners and pipe roots are "rounded or obtuse with cement mortar," which eliminates sharp edges and prevents cracking of the waterproof layer due to stress concentration at the corners. At the same time, it allows the subsequent application of waterproof coatings and the laying of mortar to adhere better to the base, improving the adhesion between the waterproof layer and the base and reducing the risk of leakage related to the base.

[0014] Preferably, in step five, the water storage test requires first sealing the floor drain, then forming a closed area through a water-blocking mechanism, filling the area with water to a preset water level and maintaining it for a specified time. If there is no leakage during this period, the test is qualified. If leakage occurs, the leaking part needs to be repaired. After the repair is completed, the local water storage test is carried out again until there is no leakage. By adopting the above technical solutions, "sealing the floor drain" before the water storage test can prevent the test water from flowing out of the floor drain and ensure that the test area can normally store water; "forming a closed area through the water-blocking mechanism" allows the test water to remain only in the waterproof area, making it easy to observe whether there is leakage; specifying "keeping the water at the preset water level for a specified time" allows the waterproof layer to fully contact the water, and any potential leakage can be fully revealed, ensuring comprehensive testing; specifying "repairing after leakage and conducting another local water storage test" can address leakage problems in a targeted manner, avoiding leakage in later use due to missed leakage points. Through the closed-loop process of "testing-repairing-retesting", it is ensured that the waterproof structure is ultimately leak-free, guaranteeing the waterproof effect is qualified. Beneficial effects

[0015] In summary, this application includes at least one of the following beneficial technical effects: This invention provides a waterproof structure and construction process for an entrance garden. It involves setting up a base layer, which is a floor slab structure free of dust, debris, and defects such as hollow areas and cracks. The corners and pipe roots are rounded or obtuse angles. During construction, the base surface is first cleaned and leveled, then the corners and pipe roots are rounded / obtuse to prevent damage to the subsequent waterproof layer caused by unevenness or sharp edges. This provides a stable and flat foundation for the subsequent waterproof structure, reducing the risk of cracking and leakage caused by base defects and solving the problem of incomplete base treatment in existing technologies. An additional layer, made of waterproof coating, is applied around the pipe roots, drains, and corners of the base layer. This waterproof coating is a flexible, elastic material. During construction, a circular coating is applied around the pipe roots and drains, and a continuous coating is applied along the corners. To ensure the coating is free of bubbles and missed spots, special reinforcement sealing is applied to the details of the entrance garden that are prone to leakage. The flexible waterproof coating can adapt to minor deformations of the building, preventing leakage at the joints due to structural deformation or construction oversights, thus solving the problem of incomplete treatment of details in existing technologies. A rigid waterproof layer is set up, which is made of polymer waterproof mortar and covers the entire surface of the base structure layer and the additional detailed layer. During the work process, the base layer and the additional detailed layer are cleaned and moistened before laying. During laying, a troweling process is used to ensure that the mortar adheres tightly. After laying, the surface is smoothed. The polymer waterproof mortar has both rigid strength and a certain degree of flexibility, which avoids the problem of cracking of ordinary rigid waterproofing and makes up for the poor durability of flexible waterproofing. At the same time, the entire coverage forms a complete waterproof surface, improving the overall seepage resistance of the entrance garden and solving the problem of poor effect of single flexible or rigid waterproofing in existing technologies.

[0016] This invention provides a waterproof structure and construction process for an entrance garden. By setting up a water-retaining mechanism—a water-retaining sill formed by pouring cement mortar—it is tightly bonded to the base layer, with a smooth inner surface and a smooth, compacted top surface. During operation, the water-retaining sill blocks water flow during water storage tests, forming a closed area for easy inspection. This ensures the water storage test is conducted correctly, accurately detecting any leakage in the waterproof layer. Simultaneously, the tight connection between the water-retaining sill and the base layer prevents leakage due to defects in the water-retaining structure during the test, thus improving the quality control of waterproof construction and solving the problem of non-standard water storage tests in existing technologies. By combining detailed additional layers with a rigid waterproof layer, the detailed additional layers are constructed first to reinforce the joints, followed by the rigid waterproof layer covering the entire structure. This forms a composite waterproof system of "flexible joint sealing + overall rigid protection," balancing joint sealing performance and overall waterproof durability. It adapts to building deformation and possesses high impermeability, solving the problems of easy failure and poor durability of single waterproofing methods in existing technologies.

[0019] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0020] Example 1: A waterproof structure for an entrance garden, referring to... Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7The system comprises a base structure layer 1, a detailed supplementary layer 2, a rigid waterproof layer 3, and a water-retaining mechanism 4. The base structure layer 1 is a floor slab structure 11 with a surface free of dust, debris, and defects such as hollow areas and cracks in the entrance garden. The corners and pipe roots of the base structure layer 1 are rounded or obtuse angles. The detailed supplementary layer 2 is laid around the pipe roots, floor drains, and corners of the base structure layer 1. The rigid waterproof layer 3 completely covers the surfaces of the base structure layer 1 and the detailed supplementary layer 2. The water-retaining mechanism 4 is located at the entrance of the entrance garden. The detailed supplementary layer 2 is made of waterproof coating 21, which is evenly applied around the pipe roots, floor drains, and corners. The rigid waterproof layer 3 is made of polymer waterproof mortar 31, which is mixed according to a preset ratio and then laid on the surfaces of the base structure layer 1 and the detailed supplementary layer 2. The water-retaining mechanism 4 is a water-retaining sill 41 formed by pouring cement mortar. The water-retaining sill 41 is tightly bonded to the base structure layer 1, providing protection for the base structure. Layer 1 explicitly requires "no dust, debris, hollow areas, or cracks" and "rounded or obtuse angles for internal and external corners and pipe roots." This prevents impurities in the base layer from causing insufficient adhesion of the waterproof layer or sharp edges from scratching it, providing a smooth and defect-free foundation for subsequent waterproofing structures and reducing the risk of damage to the waterproof layer from the source. Detailed additional layer 2 is precisely placed at easily leaking nodes such as pipe roots, floor drains, and internal and external corners, specifically strengthening waterproofing in weak areas. Simultaneously, the rigid waterproof layer 3 completely covers the base layer and detailed additional layer 2, forming a double-layer waterproofing structure of "specific node protection + overall comprehensive protection." This solves localized leakage problems while ensuring overall waterproofing effectiveness. The water-blocking mechanism 4 uses a water-blocking sill 41 that is tightly integrated with the base layer. It can stably block water flow during water storage tests, preventing test water from overflowing and ensuring the test can be carried out normally. This accurately detects whether there are leaks in the waterproof structure, ensuring the quality of waterproofing construction meets standards, and ultimately constructing a complete and comprehensive waterproofing system for the entrance garden.

[0021] Reference Figure 1 , Figure 3 and Figure 5The waterproof coating 21 is an elastic flexible waterproof coating 21. During the application process, it is applied in a ring around the pipe roots and floor drains, and continuously along the inside and outside corners. Before laying the polymer waterproof mortar 31, the surfaces of the base structure layer 1 and the detailed additional layer 2 are cleaned and moistened. During the laying process, a troweling process is used to ensure that the mortar adheres tightly to the base layer. After the laying is completed, the surface of the rigid waterproof layer 3 is smoothed. The waterproof coating 21 is defined as an "elastic flexible waterproof coating 21", whose elasticity can adapt to the slight deformation caused by building settlement and temperature changes, avoiding cracking of the coating due to structural deformation and solving the problem of cracking and failure of traditional rigid coatings. The process of "ring-shaped application around pipe roots and floor drains, and continuous application along the inside and outside corners" ensures that the waterproof coating 21 completely adheres to the node outline without any blind spots. At the same time, it is required to be "air-free". The "soaking and no-missing brushing" process avoids gaps caused by improper brushing, further enhancing the sealing and waterproofing performance of key nodes such as pipe roots, floor drains, and internal and external corners, reducing the probability of leakage at these nodes. Before laying the polymer waterproof mortar 31, the surface of the base layer and the detailed additional layer 2 is "cleaned and moistened" to remove surface dust and impurities, while keeping the base layer moderately moist to prevent the mortar from being absorbed too quickly by the base layer, which would cause shrinkage and cracking. This also enhances the adhesion between the mortar and the base layer, preventing hollow areas between the mortar and the base layer. The "troweling process" used during laying removes air from the mortar, allowing the mortar to adhere tightly to the base layer and the detailed additional layer 2, reducing internal gaps. The "smoothing treatment" after laying fills the tiny pores on the mortar surface, improving the density of the rigid waterproof layer 3, thereby enhancing its impermeability and solving the problem of poor impermeability caused by the high porosity and low density of traditional rigid waterproof layers 3.

[0022] Reference Figure 1 , Figure 2 and Figure 7 When the water-retaining sill 41 is poured, it forms an integral connection with the wall or ground structure at the entrance of the garden. The surface of the water-retaining sill 41 facing the inside of the garden is smoothed, and the top end face of the water-retaining sill 41 is finished and compacted. The "integral connection" between the water-retaining sill 41 and the surrounding structure during pouring avoids gaps between the water-retaining sill 41 and the surrounding structure, preventing test water from leaking out from the joint. This solves the problem of test water leakage caused by loose joints in traditional water-retaining structures. The "smoothing" of the inner surface of the water-retaining sill 41 and the "finishing and compacting" of the top end face eliminate surface roughness, protrusions, or loose particles, preventing the waterproof layer from being scratched by rough edges or the water from seeping out due to loose end faces. This ensures that the water-retaining sill 41 itself has no leakage risk, providing reliable water-retaining protection for the water storage test and ensuring accurate test results.

[0023] This application also discloses a waterproofing construction process for an entrance garden, which is applicable to one of the above-mentioned entrance garden waterproofing structures. The construction steps are as follows: Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 Step 1: Construction preparation, including technical preparation, material preparation, construction equipment preparation, construction personnel preparation, and inspection of working conditions; Step 2: Base treatment, cleaning and leveling the surface of the base structure layer 1, and treating the corners and pipe roots; Step 3: Construction of the detailed additional layer 2, applying waterproof coating 21 around the pipe roots, drains, and corners of the base structure layer 1 to form the detailed additional layer 2; Step 4: Construction of the rigid waterproof layer 3, laying polymer waterproof mortar 31 on the surface of the base structure layer 1 and the detailed additional layer 2 to form the rigid waterproof layer 3; Step 5: Water retention test, using a water-blocking mechanism 4 to block water flow towards the rigid waterproof layer. 3. Conduct a water retention test on the surface to confirm there is no leakage, and then complete the construction. A complete process has been established: "Construction Preparation → Base Treatment → Construction of Additional Detail Layer 2 → Construction of Rigid Waterproof Layer 3 → Water Retention Test." This provides clear step-by-step guidance for waterproofing construction, avoiding confusion. Each step is interconnected: construction preparation lays the foundation for subsequent construction; base treatment ensures the adhesion of the waterproof layer; additional detail layer 2 and rigid waterproof layer 3 address specific nodes and overall protection, respectively; and the water retention test verifies the final quality. This standardized construction system reduces waterproofing defects caused by disordered construction sequence or missing steps, improves construction standardization, and ensures consistent and stable waterproofing results.

[0024] Reference Figure 1 , Figure 3 and Figure 5Step one's technical preparation includes reviewing construction drawings and design change documents, mastering relevant waterproofing specifications and technical standards, understanding the performance and operation process of waterproofing materials, preparing a waterproofing construction plan, and providing written technical instructions to construction personnel; material preparation requires ensuring that materials such as polymer waterproof mortar 31 and waterproof coating 21 have factory certificates of conformity and quality inspection reports, and that witnessed sampling and re-inspection are conducted according to specifications, with materials only being used after passing the re-inspection; preparation of construction tools includes preparing plastic containers, scrapers, brushes, trowels, putty knives, brooms, and fire-fighting equipment; construction personnel must possess the corresponding qualifications, have undergone professional training, and be certified to work; and inspection of working conditions. The inspection should confirm that pipes penetrating the floor slab and floor drains are securely installed and have passed inspection. Pipe holes and reserved openings must be sealed tightly with fine aggregate concrete. Step two, the base treatment, requires first removing dust, debris, hardened mortar lumps, and protruding parts from the surface of the base structural layer 1, then leveling the surface to ensure it is clean and flat. For internal and external corners and pipe roots, cement mortar should be used to create rounded or obtuse angles to ensure a smooth transition. In the technical preparation phase, "reviewing drawings, mastering specifications, preparing plans, and providing technical instructions" ensures that construction personnel understand the design requirements and operating standards, avoiding construction errors due to misunderstandings. Material preparation requires that "materials have certificates of conformity and test reports." "And the re-inspection is qualified," which can prevent the use of substandard materials, ensuring waterproofing performance from the source and avoiding waterproofing failure due to poor material quality; the preparation of complete construction equipment and tools can ensure the smooth progress of the construction process and avoid the impact of missing equipment on construction efficiency or quality; requiring construction workers to "possess qualifications, undergo professional training and hold certificates" can ensure that construction workers operate in accordance with regulations, reducing waterproofing problems caused by improper operation; the inspection of working conditions "confirms that the pipes are firmly installed and the openings are tightly sealed," which can prevent leakage caused by loose pipes or unsealed openings during subsequent construction, creating a qualified working environment for waterproofing construction, comprehensively controlling construction risks in advance, and laying a solid foundation. The first step in the layer treatment is to "remove dust, debris, hardened mortar lumps, and protruding parts," which removes obstacles from the substrate surface that may affect the adhesion of the waterproof layer and prevents hollowing or detachment of the waterproof layer due to impurities. The "leveling treatment" of the substrate ensures a smooth surface, preventing damage to the waterproof layer due to uneven stress caused by uneven substrate surfaces. The corners and pipe roots are "rounded or obtuse with cement mortar," eliminating sharp edges and preventing cracking of the waterproof layer at these points due to stress concentration. This also allows the subsequent application of waterproof coating and mortar to adhere better to the substrate, improving the adhesion between the waterproof layer and the substrate and reducing potential leakage risks associated with the substrate.

[0025] Reference Figure 1 , Figure 2 and Figure 7In step five, the water storage test requires first sealing the floor drain, then forming a closed area through the water-blocking mechanism 4, filling the area with water to the preset water level and maintaining it for a specified time. If there is no leakage during this period, the test is qualified. If leakage occurs, the leaking part needs to be repaired. After the repair is completed, a local water storage test is conducted again until there is no leakage. "Sealing the floor drain" before the water storage test can prevent the test water from flowing out of the floor drain and ensure that the test area can store water normally. "Forming a closed area through the water-blocking mechanism 4" allows the test water to remain only in the waterproof area, making it easy to observe whether there is leakage. Specifying "filling the water to the preset water level and maintaining it for a specified time" allows the waterproof layer to fully contact the water, and any potential leakage can be fully revealed, ensuring comprehensive testing. Specifying "repairing after leakage and conducting another local water storage test" can address leakage problems in a targeted manner and avoid leakage during later use due to missed leakage points. Through the closed-loop process of "testing-repairing-retesting", the waterproof structure is ultimately guaranteed to be leak-free, ensuring the waterproof effect is qualified.

[0026] The implementation principle of this application embodiment is as follows: First, construction preparation is carried out, including technical preparation, material preparation, construction equipment preparation, personnel qualification confirmation, and work condition inspection, laying a compliant and safe foundation for subsequent construction; then, base treatment is carried out, first removing dust, debris, mortar lumps, and protruding parts from the surface of the base structure layer 1, and leveling the surface to ensure cleanliness and flatness; then, the internal and external corners and pipe roots of the base structure layer 1 are smoothed with cement mortar into arcs or obtuse angles to avoid sharp edges damaging the subsequent waterproof layer, while eliminating base defects and providing a stable adhesion surface for the waterproof structure; subsequently, the detailed additional layer 2 is constructed, applying waterproof coating 21 around the pipe roots, around the floor drain, and at the internal and external corners of the base structure layer 1 to form the detailed additional layer 2; during application, a circular wrapping application is made around the pipe roots and floor drain, and a continuous application is made along the internal and external corners to ensure that the coating is free of bubbles and missed areas, utilizing the sealing performance of the elastic flexible waterproof coating 21 to prevent easy seepage. Specific protection measures are implemented for leaky details to accommodate minor building deformations and prevent leakage. Then, the rigid waterproof layer 3 is constructed. Before laying the polymer waterproof mortar 31, the surfaces of the base structure layer 1 and the additional detail layer 2 are cleaned and moistened. During laying, a troweling process is used to ensure the polymer waterproof mortar 31 adheres tightly to the base and additional detail layer 2. After laying, the surface of the rigid waterproof layer 3 is smoothed to reduce porosity. The polymer waterproof mortar 31 completely covers the surfaces of the base structure layer 1 and the additional detail layer 2, forming an overall waterproof surface that combines rigidity and flexibility, improving impermeability and compensating for the shortcomings of single waterproofing methods. Finally, a water retention test is conducted. The water-blocking mechanism 4 blocks water flow at the entrance garden, forming a closed area. Water is poured onto the surface of the rigid waterproof layer 3 to a preset level and maintained for a specified time to check for leaks. If leaks are found, they are repaired and tested again locally until there are no leaks, ensuring the overall waterproofing effect of the waterproof structure is qualified.
