Description

Technical Field

[0001] This utility model belongs to the field of waterproofing technology for green roofs, specifically, it relates to a structure for the application of self-adhesive waterproof membrane on green roof slabs. Background Technology

[0002] Currently, the common structural layers for waterproofing planting roofs are: structural roof slab, leveling layer, waterproof layer, root-penetration resistant waterproof membrane layer, siphon drainage system, planting soil layer, and vegetation layer. The waterproof layer is a non-curing rubber asphalt waterproof coating, and the root-penetration resistant membrane is a modified bitumen root-penetration resistant waterproof membrane.

[0003] The above-mentioned waterproofing methods have the following drawbacks: 1. The hot-melt construction method used in the roll material construction process cannot avoid the environmental pollution problems caused by hot-melt construction; 2. The application of non-curing rubber asphalt waterproof coating requires heating to a specified temperature, and the required thickness is difficult to control effectively. The heating process generates a large amount of smoke emissions, which does not conform to the green concept of low carbon and environmental protection; 3. It is difficult to detect whether there are leaks at the joints between the roll materials, which also poses a certain risk to the waterproofing effect; 4. The construction period for two waterproof layers is long, the construction is complicated, and the building design cost is high. The purpose of this utility model is to address the problems of the above-mentioned existing technologies by providing a brand-new, zero-leakage, low-carbon, environmentally friendly, quick-construction, short-term construction period, and low-overall cost orderly waterproofing and drainage structure for planted roof slabs. Utility Model Content

[0004] To solve the above problems, the technical solution adopted by this utility model is: a structure for the application of self-adhesive waterproof membrane in a planted roof, the structure comprising, from bottom to top, a waterproof concrete base layer, a leveling layer, a siphon drainage system, a planting soil layer and a vegetation layer, wherein a prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane is provided between the leveling layer and the siphon drainage system.

[0005] A further technical solution is that the leveling layer is a 20mm thick M15 mortar (water: mortar ratio 1:3).

[0006] A further technical solution is that the prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane consists of a strong cross-laminated film + modified bitumen coating layer + PET base film + modified bitumen coating layer + release film layer from top to bottom, with an overall membrane thickness of 3.0-5.5mm.

[0007] A further technical solution is that the thickness of the high-strength cross-linked film is 0.08-0.11 mm; the thickness of the PET base film is 0.10-0.15 mm; and the separation film layer is an aluminized separation film with a thickness of 0.025-0.035 mm or an adhesive separation film with a thickness of 0.030-0.045 mm.

[0008] A further technical solution is that the siphon drainage system is a geotextile composite polymer drainage and storage board combined with a high-strength drainage trough.

[0009] A further technical solution is that the long and short sides of the geotextile composite polymer drainage and storage board are both fixed by overlapping double-sided self-adhesive rolls, and the geotextile overlaps are connected by spot bonding with high-strength adhesive.

[0010] A further technical solution is that the waterproofing system of the present invention also includes an additional waterproof layer, which is disposed at the pipe roots and internal and external corners of the leveling layer, and is located between the leveling layer and the prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane layer.

[0011] A further technical solution is that the modified asphalt coating layer contains a root inhibitor, and the root inhibitor can be either Lanxess (Germany) or Büscherhofer (Austria).

[0012] A further technical solution is that the overlap width of the adjacent short sides of the prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane is greater than or equal to 80mm, and the overlap method of the adjacent short sides of the membrane is an interlocking type with a 2+1 overlap design. The overlap layer is made of a coating layer containing root inhibitor.

[0013] The beneficial effects of adopting the above technical solution are as follows: 1. This utility model firstly uses a prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane, which can achieve the design effect of one waterproof layer meeting the waterproof requirements of two layers of root-penetration resistant waterproof membrane. 2. The prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane uses a polymer film base as the prefabricated composite material. The excellent elongation performance of the polymer film base can effectively absorb the stress generated by the deformation and cracking of the reinforced concrete roof slab. In addition, the overlapping edge adopts a 2+1 interlocking overlapping edge design, which will not produce pull-out cracks at the overlapping part of the membrane, and the bonding effect of the overlapping edge is more reliable. 3. The entire membrane waterproofing construction adopts a skin-like bonding method, which can effectively eliminate open flame operations, eliminate the environmental pollution problems caused by hot-melt construction, save the entire waterproofing construction period, and reduce the overall cost. 4. The combination of prefabricated double-layer root-penetration resistant waterproof membrane and the polymer layer of the siphon drainage system results in excellent root-blocking performance. The geotextile composite polymer drainage and water-retaining board possesses excellent chemical stability, resists chemical corrosion and aging, effectively resists mold corrosion from plants and soil, and exhibits excellent physical root-blocking performance. Simultaneously, the prefabricated double-layer root-penetration resistant waterproof membrane provides dual protection against physical and chemical root-blocking, reliably ensuring the drainage performance of the underground garage's planting roof slab. 5. Through the rational distribution of high-strength drainage channels, the entire base surface is divided into several small water-retaining and drainage zones. Excess water is ultimately discharged in a unified and orderly manner through the drainage channels, ensuring that the moisture content of the planting soil meets the needs of plant growth.

[0017] To make the objectives and technical solutions of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit its scope. Example 1

[0018] like Figure 1As shown, a structure for the application of self-adhesive waterproof membrane in a planted roof slab includes, from bottom to top, a waterproof concrete base layer 1, a leveling layer 2, a siphon drainage system 4, a planting soil layer 5, and a vegetation layer 6. A prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane 3 is provided between the leveling layer 2 and the siphon drainage system 4. The prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane 3 consists of, from top to bottom, a strong cross-laminated film + a modified bitumen coating layer + a PET base film + another modified bitumen coating layer + a release film layer. It is prefabricated using two layers of high-polymer structural films. The overall thickness of the membrane is 3.0-5.5mm. The entire waterproofing construction uses a skin-like adhesive method to achieve full adhesion to the substrate. The overlap edges use a 2+1 interlocking adhesive method to achieve zero leakage. The prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane uses a high-polymer film base as the prefabricated composite material. The excellent elongation properties of the high-polymer film base can effectively absorb the stress generated by the deformation and cracking of the reinforced concrete roof slab. The unique overlapping method prevents stress at the membrane overlap. Pull-out cracks and overlapping edge bonding effects are more reliable; and the modified asphalt coating layer in the precast double-layer root-penetration resistant membrane is entirely coated with root inhibitors. The root inhibitors can effectively prevent plant roots from penetrating and damaging the waterproof layer and the building, but without harming the plant roots or affecting the normal growth of the plants. The root inhibitors are either Lanxess from Germany or Büchner from Austria; the siphon drainage system 4 is a geotextile composite polymer drainage and storage board combined with a high-strength drainage channel; the waterproof and drainage polymer layer geotextile and the polymer drainage and storage board are connected by point bonding, and the connection points use special adhesives, resulting in a strong bonding effect; the polymer drainage and storage board consists of a flat base layer and columnar protrusions, with the columnar protrusions evenly distributed and integrally formed with the base layer. Example 2

[0019] An additional layer is added to areas prone to leakage, such as pipe roots and internal / external corners, in the leveling layer 2. This additional layer is located between the leveling layer 2 and the precast double-layer root-penetration-resistant self-adhesive waterproof membrane 3, and its width is preferably 500mm. The thickness of the precast double-layer root-penetration-resistant self-adhesive waterproof membrane 3 is 3.0-5.5mm.

[0020] The construction process of the leveling layer 2 is as follows: 1. Base cleaning: The base after shot blasting should be firm, moist, free of dust and oil. 2. Mixing cement mortar: Add cement mortar according to the mix ratio of 20mm thick DS M15 mortar (1:3 cement mortar). Do this before large-area plastering at pipe roots, embedded parts, and internal and external corners. After leveling and compacting the specified thickness of the leveling layer, finally cure it. Example 3

[0021] The overlap width of the prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane 3 shall not be less than 80mm, and the short side overlap interval between adjacent membranes shall be more than 500mm.

[0022] The construction process for prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane 3 is as follows: 1. Determine the baseline; 2. Stress release: Before on-site construction, the membrane should be pre-laid to fully release the concentrated stress of the membrane. 3. Additional layer membrane installation: Before large-area construction, prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane should be bonded to pipe roots, embedded parts, and internal and external corners as an additional layer. The additional layer should be 500mm wide and fully bonded to the leveling layer 2. 4. Large-area membrane installation: Install the membrane according to the baseline, adjust the installation position, and first attach the end of the membrane to the leveling layer. Slowly roll it forward to remove air and ensure tight adhesion. The installed membrane should be flat, straight, and have correct overlap dimensions, without twisting. Adjacent membranes should be firmly bonded, with an overlap width of not less than 80mm on both long and short sides. The short side overlap seams of adjacent membranes in the same layer should be staggered by more than 500mm. V. Treatment of roll material overlap joints: Long and short side overlap joints shall use self-adhesive bonding; short side overlap joints shall use a 2+1 interlocking overlap, such as... Figure 2 As shown in Figure 3. Example 4

[0023] The siphon drainage system 4 is a geotextile composite polymer drainage and storage board combined with a high-strength siphon drainage trough.

[0024] The construction process of the siphon drainage system 4 is as follows: 1. Use special double-sided self-adhesive roll material to fix the high-strength siphon drainage channel according to the design requirements; 2. Lay the geotextile composite polymer drainage and storage board with flat joints, laying it parallel to the determined drainage direction; 3. Use special self-adhesive roll material to fix the long and short sides of the geotextile composite polymer drainage and storage board; use special strong adhesive to spot bond the composite geotextile. Install pressure balance pipes at the corresponding positions in the drainage channel according to the design requirements. 4. Lay 800mm wide geotextile on the high-strength siphon drainage channel, using special adhesive to spot bond the geotextile. 5. Connect the drainage channel to the outlet position of the top slab according to the design requirements. 6. Install rainwater observation and sedimentation wells according to the design requirements and connect them to the high-strength siphon drainage channel at the outlet position of the top slab. 7. Backfill soil using a simultaneous laying and filling method; construction machinery must not directly contact the tidal orderly drainage and waterproof polymer layer; equipment can only be installed after backfilling. 8. Treatment of irregularly shaped areas: The geotextile composite polymer drainage and storage board laid on the side wall should be laid from top to bottom, with a laying height of 500mm, and fixed to the waterproof layer. The bottom end should be folded over onto the geotextile composite polymer drainage and storage board laid flat on the top slab, extending 100mm. The geotextile should be folded into the gap between the polymer drainage and storage board and the wall by 100mm. 9. Rainwater collection outlets should be set at the edge of leveling layer 2 to collect water from the planting soil into the siphon drainage channel, and then sucked into the sedimentation observation well under the siphon action. The water will then be discharged into the rainwater collection system for recycling through the sedimentation observation well.

[0025] In summary, the structure designed for the application of self-adhesive waterproof membrane in green roof slabs not only efficiently utilizes rainwater resources in conjunction with a siphon drainage system, but also significantly improves waterproofing construction efficiency. The use of prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane achieves a skin-like, full-adhesion waterproofing effect, while its low-carbon and environmentally friendly construction process effectively eliminates open flame operations. A single waterproofing application can also shorten the construction period and reduce the overall cost of waterproofing construction. The siphon drainage system effectively prevents rainwater erosion from damaging the building. The use of prefabricated double-layer root-penetration resistant self-adhesive waterproof membrane simultaneously achieves the dual effects of environmental beautification and building waterproofing.
