Heat-insulating and waterproof system of planted roof and construction method thereof

Abstract

The invention discloses a heat-insulating and waterproof system of a planted roof and a construction method thereof. The heat-insulating and waterproof system comprises an inverted roof, a siphon type roof drainage system and a rainwater collection and reuse device, wherein a structure layer, a sloping layer, a leveling layer, a waterproof layer, an XPS board heat-insulating layer, a root separating protective layer, a drainage layer, a geotechnical cloth filter layer and a planting soil layer are sequentially arranged on the inverted roof. The construction method comprises the construction steps: (1) cleaning the structure layer; (2) constructing the sloping layer and the leveling layer; (3) laying an HDPE (High Density Polyethylene) film waterproof layer; (4) laying the XPS board heat-insulating layer; (5) constructing the root separating protective layer; (6) constructing the drainage layer; (7) laying the geotechnical cloth filter layer; (8) constructing the planting soil layer; (9) carrying out acceptance check. According to the heat-insulating and waterproof system of the planted roof and the construction method thereof, the defects of the traditional roofs are improved, and the service life of the waterproof layer is effectively prolonged; through additionally arranging the siphon type roof drainage system and the rainwater collection and reuse device, rich precipitation resources can be excellently utilized, the consumption of tap water is lowered, and the improvement on the current situation that water resources are scarce is facilitated.

Description

technical field [0001] The invention relates to a planting roof heat preservation and waterproof system and a construction method thereof. Background technique [0002] With the continuous deepening of the urbanization process, the construction land in the city is becoming more and more tense, the energy is excessively consumed, the green area is reduced, and the quality of the living environment is deteriorating day by day. As an effective energy-saving and environmental protection measure, planted roof has been paid more and more attention by people. It not only has the functions of heat preservation, heat insulation, climate improvement and air purification, but also plays a role in reducing heat island effect, degrading floating dust in the air, integrating urban environment and creating A harmonious society also has good effects, and it can also increase the urban green area and beautify the living environment. [0003] The construction method of the steel structure th...

Problems solved by technology

However, this invention is directly affected by the natural environment like the roof waterproof layer constructed by traditional construction methods, and is easily damaged by the natural environment and man-made. The service life is shortened, and the waterproof layer must be repaired. At the same time, the rainwater on the roof cannot be used and can only pass through the sewer. Flowing into the river is a waste of water resources and is not conducive to improving the scarcity of water resources
