Embodiment Construction

[0009] Each layer material and structure among the present invention:

[0010] For the roof of new buildings, the green roof adopts a five-layer structure, namely waterproof layer, drainage layer, filter layer, planting layer, and vegetation layer. The material and thickness of each layer are: the waterproof layer is two layers of PVC waterproof membrane, with a total thickness of 5mm; the drainage layer: blast furnace slag, broken bricks, broken tiles, crushed stones, broken concrete blocks or a mixture of several materials , Thickness: 5-10cm; filter layer: use two layers of non-woven fabric, about 1mm thick; planting layer: use foundation dregs (or cinder soil or a mixture of the two) and garbage compost, a small amount of long-term chemical fertilizer and bacterial fertilizer. In addition, generally some organic matter and clay should be applied to improve water retention performance, thickness: 5-15cm Vegetation layer: determined according to the climate of the area and t...

Abstract

The present invention discloses a method for greening roof by utilizing solid discarded wastes. It is characterized by successively laying water-proofing layer, water-discharging layer, filtering layer and planting layer so as to attain the goal of greening roof. The water-proofing layer utilizes PVC water-proofing sheet material, the water-discharging layer is made up by using blast furnace slag, broken brick, broken tile, broken stone and broken concrete block, the filtering layer is made of non-woven fabric and the planting layer is mainly formed from ground soil, coal cinder and composting soil.

Description

technical field [0001] The invention relates to a method for greening the roof, in particular to a method for greening the roof mainly by using solid waste. Background technique [0002] With the rapid development of my country's urban construction and the rapid growth of urban population, the solid waste generated in cities has also increased geometrically. Now many cities in our country are surrounded by all kinds of garbage. It is an urgent task to study how to utilize solid waste and reduce its pressure on the urban environment. At the same time, my country's cities generally have problems of excessive building density, low green area ratio, and deterioration of urban ecological environment. The central area of ​​some cities is hardened by concrete even more than 80% of the total area. Too little urban green area will bring problems such as heat island effect, waterlogging, and poor landscape, which have seriously affected the quality of life of the urban population. ...
