Embodiment 1

[0084] Embodiment one sees Figure 1-3 As shown, a green roof structure includes a roof structure layer 1, and also includes a waterproof insulation layer 2, a protective isolation layer 3, and a solid The aquifer 4, the soil layer 5, the soil barrier 6, the soil layer 7 and the plant layer 8.

[0085] The waterproof and thermal insulation layer 2 is a waterproof thermal insulation layer of acrylic acid recycling fibers resistant to root puncture.

[0086] The protective isolation layer 3 is laid on the upper side of the waterproof insulation layer 2 in the same laying direction as the waterproof insulation layer 2, and the junction with the facade wall is turned up 100mm, and the vertical and horizontal overlap width is 100mm. When encountering pipes and tube wells protruding from the roof, turn up 100mm. The protective isolation layer 3 is an acrylic recycled fiber layer. Material grade 2, material thickness about 3mm, weight about 300g per square meter, resist mechanical...

Embodiment 2

[0096] Embodiment two see Figure 4 As shown, a green roof structure is different from the first embodiment in that it also includes the upper side of the roof structure layer 1 and the sidewalk area between the soil barriers 6 in the planting areas on both sides.

[0097] The sidewalk area includes a waterproof insulation layer 2, a protective isolation layer 3, a double-layer PE film sliding layer 9, a drainage board 10, a crushed stone mixture layer 11 and a road slab layer that are sequentially compounded on the upper surface of the roof structure layer 1 from bottom to top. 12.

[0098] The double-layer PE film sliding layer 9 is laid on the upper side of the protective isolation layer 3, and both ends extend toward the planting area.

[0099]The drainage board 10 is laid on the upper side of the double-layer PE film sliding layer 9, the drainage board is FKD 10, made of high-density polyethylene recycled material, and the polypropylene PP filter layer is about 10mm thic...

Embodiment 3

[0102] Embodiment three see Figure 5 As shown, a green roof structure is different from the second embodiment in that the sidewalk area is also provided with a floor drain area, and the roof structure layer 1 of the floor drain area forms a floor drain that is disconnected from small to large steps from bottom to top. Space 13, the four sides of the floor drain space are provided with a transition layer 14 adapted to and connected to the shape of the roof structure layer 1, and the middle part of the floor drain space penetrates up and down.

[0103] The upper surface of the edge of the transition layer 14 is flush with the upper surface of the roof structure layer 1, the upper surface of the transition layer 14 gradually slopes downward from the edge to the center, and the upper surface of the transition layer 14 is It is connected with a waterproof insulation layer 2, a protective isolation layer 3, a double-layer PE film sliding layer 9 and a drainage board 10, which exten...

Abstract

The invention relates to a green roof structure and a construction method thereof. The green roof structure comprises a roof structural layer and further comprises a waterproof heat-preservation layer, a protective isolation layer, a solid water drainage and storage layer, a soil-isolating layer, a soil-isolating baffle, a hilling layer and a plant layer. The plant layer comprises herbaceous plantseeds and crassulaceae plant seedlings. The green roof structure is an energy-saving and environment-friendly system utilizing plants planted on a roof top plate to hinder solar energy so as to prevent a room from overheating. The principle of the green roof structure is that through laying construction of all the layers such as the protective isolation layer, the water drainage and storage layer, the soil-isolating layer, the hilling layer and the plant layer, a heat-insulation, anti-seepage, environment-friendly and energy-saving overall covering roof system is formed. The green roof structure has the characteristics that the construction speed is high, the cost is low, the weight is low, maintenance is hardly needed, and the number of checking times is small.

Description

technical field [0001] The invention relates to the field of roof greening, in particular to a green roof structure and a construction method thereof. Background technique [0002] The green roof is based on the characteristics of relatively small building loads, using lawns, ground covers, small shrubs and climbing plants to cover green roofs and underground building roofs. Paths and courtyards can be left on the roof for people to walk and stay. Existing green roofs generally use lawns, but irrigation systems need to be set up separately, which wastes resources; at the same time, existing green roofs are only building roofs supplemented with planting soil or containers for planting plants, which have poor integration with the roof and cannot be formed. It has a multi-functional heat insulation, anti-seepage, environmental protection and energy-saving overall covering roof system; at the same time, the cost is high and the maintenance cost is high.
