Description

Technical Field

[0001] This utility model relates to the field of building waterproofing and drainage construction technology, specifically to an organized polymer waterproofing and drainage system for planted roof slabs. Background Technology

[0002] Currently, the construction methods for waterproofing and drainage structures of basement green roof slabs involve multiple layers, typically including, from bottom to top, a slope-finding layer, a leveling layer, a waterproofing layer, an isolation layer, a fine aggregate concrete protective layer, a drainage layer, a filter layer, and a planting layer. This can easily lead to difficulties in slope and leveling, numerous overlapping work surfaces, complex construction, high project costs, and management difficulties. At the same time, the drainage porosity is small, which can easily damage the filter layer and cause blockages, resulting in problems such as waterlogging and water seepage.

[0003] Meanwhile, waterproofing layers typically use a combination of non-curing asphalt coatings and modified asphalt root-penetration resistant waterproof membranes. However, the non-curing asphalt coatings generate a large amount of fumes during the chemical processing and construction, which pollutes the environment. The root-blocking effect of the waterproofing layer mainly depends on the chemical root inhibitors in the modified asphalt membrane and the quality of the membrane overlaps. This is highly susceptible to the precision of the membrane production process and the skill level of the waterproofing operators. Therefore, the existing technology cannot guarantee the waterproofing and drainage effect of the roof slab.

[0004] The "General Specification for Waterproofing of Buildings and Municipal Engineering" clearly requires that the design service life of waterproofing for underground engineering projects should not be less than the design service life of the engineering structure. Therefore, in order to ensure the durability of the waterproofing layer, a reasonable and new type of planting roof drainage system is urgently needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the prior art by providing an organized polymer waterproofing and drainage system for planting roofs.

[0006] This utility model provides a waterproofing and drainage system for a planting roof, which adopts the following technical solution:

[0007] An organized polymer waterproofing and drainage system for a planting roof is characterized by comprising, from bottom to top, a reinforced concrete roof slab, a polymer waterproof layer, a polymer root-penetration resistant waterproof layer, a polymer siphon drainage layer, and a planting soil layer, which are stacked sequentially.

[0008] Preferably, the material of the polymer waterproof layer is any one or two of polymer waterproof membrane or polymer waterproof coating.

[0009] Preferably, the material of the polymer root-penetration resistant waterproof layer is a polymer root-penetration resistant waterproof membrane.

[0010] The polymer waterproof layer is bonded to the polymer root-penetration resistant waterproof layer.

[0011] Preferably, when the polymer waterproof layer is a polymer waterproof membrane, both the polymer waterproof layer and the polymer root-penetration resistant waterproof layer include a self-adhesive layer and a polymer substrate layer. The self-adhesive layer on the polymer waterproof layer effectively bonds the polymer waterproof layer to the reinforced concrete roof slab, and the self-adhesive layer on the polymer root-penetration resistant waterproof layer bonds the polymer waterproof layer to the polymer root-penetration resistant waterproof layer. The self-adhesive layer is a non-asphalt-based self-adhesive layer, selected from pressure-sensitive adhesives or butyl adhesives. The polymer substrate layer is an HDPE sheet layer, a TPO sheet layer, a TPR sheet layer, or a PVC sheet. The polymer waterproof layer is selected from any one of the following: a polymer waterproof coating layer, a PET film layer, a strong cross-linked film layer, or a fluorocarbon film layer; if the polymer waterproof layer is a polymer waterproof coating, the polymer root-penetration resistant waterproof layer is provided with a self-adhesive layer; if the polymer waterproof layer includes a polymer waterproof coating layer and a polymer waterproof membrane layer, the polymer waterproof membrane layer includes a backing layer and a polymer substrate layer, the polymer root-penetration resistant waterproof layer includes a self-adhesive layer and a polymer substrate layer, the polymer waterproof coating layer is located between the reinforced concrete top slab and the polymer waterproof membrane layer, and is bonded to the backing layer, wherein the backing layer is made of any one or both of polyester nonwoven fabric and polypropylene nonwoven fabric.

[0012] Furthermore, the aforementioned waterproofing system is characterized in that the thickness of the polymer waterproof membrane is 1.2-4.0 mm, the thickness of the polymer waterproof coating is 1.5-3.0 mm, and the thickness of the polymer root-penetration resistant waterproof membrane is 1.2-4.0 mm.

[0013] Furthermore, the drainage system of this utility model also includes an additional waterproof layer, which is set at the pipe roots, internal and external corners and other places where water leakage is likely to occur in the reinforced concrete roof slab, and is located between the reinforced concrete roof slab and the polymer waterproof layer.

[0014] Preferably, the polymer siphon drainage layer includes a siphon composite drainage board and a siphon high-strength drainage trough, which are connected to a siphon structure, a sedimentation observation well and a water storage tank disposed on one side of the building roof slab.

[0015] The siphon composite drainage board is made of high-density polyethylene (HDPE) through extrusion and stamping. The surface is concave and convex. A layer of filter geotextile is bonded to the concave and convex top surface to prevent soil particles from passing through, thereby avoiding blockage of the drainage channel and ensuring smooth drainage of the channel.

[0016] The siphon high-strength drainage channel is injection molded from polypropylene (PP) and is in the shape of an inverted U. It has wing plates on both sides to prevent collapse and has a design to prevent damage to the geotextile. It has the functions of rapid drainage and protection.

[0017] Furthermore, the siphon structure includes a siphon pipe, one end of which is connected to the polymer siphon drainage layer, and the other end is connected to the sedimentation observation well.

[0018] The siphon pipe is a drainage pipe made of polyethylene (PE) material. By changing the diameter, rainwater quickly forms a full-pipe flow at the outlet, creating a siphon effect to achieve high-speed discharge.

[0019] The siphon high-strength drainage channel is connected to a breathable observation pipe above it. The breathable observation pipe penetrates the planting soil layer and can provide atmospheric pressure, so that the rainwater in the siphon high-strength drainage channel can form an organized flow of water without slope through atmospheric pressure. It plays a role in aeration during drought, providing oxygen to the plant roots and facilitating plant growth.

[0020] The planting soil layer is placed above the polymer siphon drainage layer and is used for planting roof plants.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) The organized polymer drainage system for planting roof provided by this utility model only has a polymer siphon drainage layer, a polymer root-penetration resistant waterproof layer and a polymer waterproof layer below the planting soil layer. It eliminates the leveling layer, slope layer, protective layer and isolation layer and other structures and steps in the traditional method, which simplifies the construction. The polymer siphon drainage layer is used to achieve organized drainage without slope and avoid water accumulation on the top. Rainwater is collected in the water storage tank through the siphon structure and sedimentation observation well, realizing the recycling and utilization of rainwater.

[0023] (2) The polymer waterproofing and drainage system for the planting roof provided by this utility model uses polymer waterproofing layer, polymer root-penetration resistant waterproofing layer and polymer siphon drainage layer, all of which are polymer materials. The main raw materials are virgin materials, and no open flame is used in the construction. It has the characteristics of being green and environmentally friendly and having good durability. More importantly, the waterproofing and drainage structure follows the compatibility principle, and the durability of the system is guaranteed. It meets the requirements of Class I waterproofing protection for underground parts in the "General Specification for Waterproofing of Building and Municipal Engineering", and ensures the quality of waterproofing.

[0024] (3) The organized polymer waterproofing and drainage system for planting roof provided by this utility model effectively intercepts plant roots by utilizing the high strength and density of the polymer substrate layer in the polymer root-penetration resistant waterproof membrane, and has excellent physical root-blocking effect.

[0025] (4) The organized polymer waterproofing and drainage system for planting roof provided by this utility model utilizes the characteristics of high tensile strength, large elongation, impact resistance and puncture resistance of polymer waterproof membrane or polymer waterproof coating and polymer root-penetration resistant waterproof membrane to effectively eliminate the stress caused by the deformation and cracking of reinforced concrete roof caused by foundation settlement. It also solves the problem of building leakage caused by cracking of the waterproof layer due to cracking of the structural base layer.

[0026] (5) In the organized polymer waterproofing and drainage system for planting roof provided by this utility model, the polymer waterproof layer is bonded to the polymer root-penetration resistant waterproof layer, and the two waterproof layers are fully bonded to achieve the overall waterproof layer not slipping, so that the waterproof membrane overlap will not come apart, and the full bonding effect prevents water leakage, thus improving the reliability of the waterproof system.

[0031] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The technical solution of this application is not only applicable to the waterproofing and drainage system of the planting roof in the basement, but also to the waterproofing and drainage system of the planting roof slab on the roof of ordinary buildings. The following examples are only used to illustrate the technical solution of this utility model more clearly, and should not be used to limit the protection scope of this utility model.

[0032] like Figure 1As shown, an organized polymer waterproofing and drainage system for a planting roof includes a reinforced concrete roof slab 1. The reinforced concrete roof slab 1 is provided with a polymer waterproof layer 2, a polymer root-penetration resistant waterproof layer 3, a polymer siphon drainage layer 4, and a planting soil layer 5 stacked sequentially from bottom to top. The polymer siphon drainage layer 4 includes a siphon composite drainage board 41 and a siphon high-strength drainage channel 42, which are connected to a siphon structure 6, a sedimentation observation well 7, and a water storage tank 8 located on one side of the building roof slab.

[0033] The polymer waterproof layer 2 is made of either polymer waterproof membrane or polymer waterproof coating, or both. The polymer root-penetration resistant waterproof layer 3 is made of polymer root-penetration resistant waterproof membrane. The polymer waterproof layer 2 is bonded to the polymer root-penetration resistant waterproof layer 3. The polymer waterproof membrane has a thickness of 1.2-4.0 mm, the polymer waterproof coating has a thickness of 1.5-3.0 mm, and the polymer root-penetration resistant waterproof membrane has a thickness of 1.2-4.0 mm.

[0034] Reference Figure 2 When a polymer waterproof membrane is selected for the polymer waterproof layer 2, both the polymer waterproof layer 2 and the polymer root-penetration resistant waterproof layer 3 include a self-adhesive layer 21 and a polymer substrate layer 22. The self-adhesive layer 21 is a non-asphalt-based self-adhesive layer, and the material is any one of pressure-sensitive adhesive or butyl adhesive. The polymer substrate layer 22 is any one of HDPE sheet layer, TPO sheet layer, TPR sheet layer, PVC sheet layer, PET film layer, strong cross-linked film layer, or fluorocarbon film layer. The self-adhesive layer 21 set on the polymer waterproof layer 2 enables the polymer waterproof layer 2 to be effectively bonded to the reinforced concrete roof slab 1. At the same time, the self-adhesive layer 21 set on the polymer root-penetration resistant waterproof layer 3 enables the polymer waterproof layer 2 to be bonded to the polymer root-penetration resistant waterproof layer 3. This achieves a full adhesion effect between the reinforced concrete roof slab 1, the polymer waterproof layer 2, and the polymer root-penetration resistant waterproof layer 3, thereby avoiding the occurrence of water seepage. When the polymer waterproof layer 2 is a polymer waterproof coating, the polymer root-penetration resistant waterproof layer 3 is provided with a self-adhesive layer 21.

[0035] Reference Figure 3When the polymer waterproof layer 2 includes a polymer waterproof coating layer 23 and a polymer waterproof membrane layer 24, the polymer waterproof membrane layer 24 includes a backing layer 241 and a polymer substrate layer 22. The polymer root-penetration resistant waterproof layer 3 includes a self-adhesive layer 21 and a polymer substrate layer 22. The polymer waterproof coating layer 23 is located between the reinforced concrete top slab 1 and the polymer waterproof membrane layer 24, and is bonded to the backing layer 241. The backing layer 241 is made of either polyester nonwoven fabric or polypropylene nonwoven fabric, or either one or both. The polymer waterproof membrane layer 24 is made of polymer waterproof coating layer 23. Layer 24 is fully bonded to the reinforced concrete roof slab 1. Simultaneously, the self-adhesive layer 21 set on the polymer root-penetration resistant waterproof layer 3 bonds the polymer waterproof membrane layer 24 to the polymer root-penetration resistant waterproof layer 3, thereby achieving a full adhesion effect between the reinforced concrete roof slab 1, the polymer waterproof layer 2, and the polymer root-penetration resistant waterproof layer 3, thus preventing water seepage. The waterproof and drainage layer of polymer material ensures the durability of the system, meets the requirements of Class I waterproofing for underground parts in the "General Specification for Waterproofing of Building and Municipal Engineering", and ensures the quality of waterproofing.

[0036] The drainage system of this utility model also includes an additional waterproof layer, which is set at the pipe roots, internal and external corners and other places where water leakage is likely to occur in the reinforced concrete top slab, and is located between the reinforced concrete top slab and the polymer waterproof layer.

[0037] Furthermore, in order to achieve organized drainage without slope on the planting roof, this utility model utilizes the siphon effect for drainage, which has a good drainage effect. Rainwater is collected in the water storage tank 8 through the polymer siphon drainage layer 4, the siphon structure 6 and the sedimentation observation well 7, realizing the recycling and utilization of rainwater.

[0038] Specifically, the construction method of the slope-free organized polymer drainage system includes the following steps:

[0039] (1) Construct polymer waterproof layer 2 and polymer root-penetration resistant waterproof layer 3 sequentially on reinforced concrete top slab 1;

[0040] (2) A polymer siphon drainage layer 4 is fully laid on the top waterproof layer. First, the siphon high-strength drainage channel 42 is used to divide the top slab into drainage zones. A 200mm wide double-sided self-adhesive roll is used to bond and fix the siphon high-strength drainage channel 42. The long side joints between the siphon composite drainage boards 41 are bonded with the 100mm wide non-woven fabric attached to the long side by applying a special polymer adhesive. The short side joints between the siphon composite drainage boards 41 can be covered with a 200mm wide non-woven fabric and bonded with a special polymer adhesive. The overlap width between each board and the non-woven fabric is 100mm. A 500mm wide geotextile is laid on the siphon high-strength drainage channel 42. The overlap between the geotextile and the drainage board geotextile is bonded with a special polymer adhesive.

[0041] (3) Install the breathable observation tube 9, which penetrates the planting soil layer 5 and is connected to the siphon high-strength drainage channel 42 at its lower end.

[0042] (4) Install the siphon structure 6 pipeline, sedimentation observation well 7 and water storage tank 8;

[0043] (5) Backfilling: The first layer of backfill should be backfilled in reverse and vehicles should not be driven directly onto the drainage board; the second layer of backfill can be used by large vehicles.

[0044] In the organized drainage system provided by this utility model, rainwater first naturally infiltrates through the soil and other matrix layers in the planting soil layer 5 and collects into the fully enclosed siphon composite drainage board 41. Then, it is guided to the siphon high-strength drainage channel 42 and organized to flow into the siphon drainage outlet. During the flow process, the change in the pipe diameter of the siphon structure 6 creates a full-pipe pressure flow, achieving a highly efficient drainage effect. The siphon structure is designed for a full-flow pressurized state, allowing for slope-free laying. The rainwater collected and discharged by the polymer siphon drainage layer 4 enters the water storage tank 8 for collection. After passing through a filtration device, the collected rainwater can be discharged through the drainage device, realizing rainwater reuse. At the same time, the breathable observation pipe 9 can provide atmospheric pressure, playing a role in ventilation during drought, providing oxygen to the plant roots, and facilitating plant growth.

[0045] By adopting the above technical solution, the shortcomings of the existing technology are improved, and a reasonable, new, and new organized polymer waterproofing and drainage system for planted roof slabs that meets the new regulations is provided. It is suitable for waterproofing and drainage construction of planted roof slabs on the top of underground buildings.
