Examples

Referring to fig. 1, the present embodiment provides a green planting roof structure with drainage, and the upper surface of the roof 30 is inclined. The planted roof structure comprises a heat insulation layer 5, a root puncture resistant waterproof coiled material 4 and a soil building module layer 2, wherein the heat insulation layer 5, the root puncture resistant waterproof coiled material and the soil building module layer are sequentially stacked on a roof base layer 6.

Wherein, the roof heat-insulating layer can adopt a polystyrene foam board. The roof insulation board is laid on the roof base layer by adopting cement paste. In order to ensure the sticking effect, the adhesive powder is used for enhancing the adhesive force. PVC pipes with the diameter of 2cm are embedded between the heat insulation plates, the pipes are mutually communicated, and small holes are formed in pipe bodies to serve as ventilation pipes. The base layer of the insulation board is guaranteed to be flat in the process, and the hollowing phenomenon is avoided.

When the root penetration resistant waterproof coiled material is constructed, a heat-insulating layer of a roof is treated by a base layer, C15 plain concrete is paved by 10cm, the uniform thickness of the waterproof base layer is ensured, the base layer is flat and firm, and is clean and dry, the internal and external corners are smeared into circular arc shape by adopting cement mortar, the minimum radius of the circular arc of the internal corner is 50mm, and the minimum radius of the circular arc of the external corner is 20 mm. And (4) strengthening the joint part, wherein at the joint of the plane and the vertical surface, the coiled material is tightly attached to the internal corner, and the additional layer and the waterproof layer are firmly adhered. The joint part must be firmly and tightly bonded, and the seam edge is not allowed to be hollow and bulged, and the edge is not allowed to slide. The lap seams of the first and second webs should be offset by 300 mm. Ensure the waterproof quality and achieve the aim of no leakage. The root-resistant waterproof roll is adopted as a waterproof material, the roll is paved along the direction parallel to the slope of the roof, each long edge is reserved with 8cm of joint, and the short edge is reserved with 10cm of joint. Then, the blowtorch is ignited to be aligned with the bottom surface of the coiled material and the surface of the base layer and is uniformly heated (the nozzle of the blowtorch is preferably about 30cm away from the surface of the coiled material), after the surface of the coiled material is melted, the coiled material is immediately rolled forwards, and is compacted and flattened, the stubble part is preferably extruded with molten asphalt, air and foreign matters are not involved during rolling, and deflection, bulging and wrinkling are prevented. Finally, the seam is sealed well by using a blast burner and a pressing pin uniformly and finely, so that the edge warping is prevented. After the laying is finished, the condition that all the surfaces of the coiled materials are torn, pierced and damaged needs to be checked, the defective parts are cleaned up during maintenance, and the coiled materials are laid again according to the strict 100mm widening of the defective parts.

Referring to fig. 2, criss-cross drainage pipelines 3 are distributed on the root-piercing-resistant waterproof coiled material, and a drainage ditch 7 is arranged at the lower edge of the roof; the lower ends of the longitudinal and transverse drainage pipelines are respectively communicated with the drainage ditches; the drainage pipeline is made of plates distributed with water permeable holes.

Referring to fig. 3, the drain pipe 3 includes a groove 31 with a downward opening and beads 32 extending outward from two sides of the bottom of the groove. The lower end face of the part, corresponding to the drainage pipeline, of the soil building module layer is provided with a notch for accommodating the groove part, and the lower surface of the soil building module layer compresses the blank pressing on the root penetration resistant waterproof roll. In this embodiment, the height of the groove may be equal to or less than 1/2, which is the height of the soil-blocking module layer.

The soil-piling module layer in the embodiment is formed by paving a plurality of prefabricated soil-piling modules, and a gap 21 is formed between every two adjacent soil-piling modules; the gap corresponds to the upper part of the drainage pipeline. The soil-piling module in the embodiment is manufactured by adopting a factory-prefabricated mode and is transported to the site for installation and construction.

The manufacturing method of the soil building module can be that the soil building module for plant planting is manufactured in a prefabrication mode. The solidified and plastic-shaped active fiber culture soil is produced by using agricultural and forestry wastes such as straws, cotton stalks and the like as main raw materials according to the structure of a nutrient medium required by good plant growth and is used as a base soil. The culture soil is fixed into modules with the size of 500 x 50mm by using iron wires, and holes which are uniformly distributed are reserved in the soil body and are used for planting plants.

In the embodiment, a gap 9 is reserved between the outer surface of the groove part and the soil building module layer, and the gap is communicated with the gap; the edge pressing is tightly pressed between the soil building module layer and the root penetration resistant waterproof coiled material in a sealing mode.
