Modular Green Roof System

Abstract

The invention relates to a modular green roof system. The modular green roof system comprises a plurality of module boxes (1) ; the bottom surface of the module box (1) is in a saw tooth structure (3), each tooth valley is provided with a perforated pipe (4), and two ends of the perforated pipe are communicated with a water collecting pipe (2) ; the middle of the water collecting pipe is connectedwith a drainage vertical pipe (5), the upper end of the drainage vertical pipe is communicated with a drainage pipe (6), and the drainage pipe is also communicated with a reservoir (7) ; a drainage layer (8), a filter layer (9), a planting layer (10) and an ultrahigh area are sequentially arranged in the module box (1) from bottom to top; a cathode (11) and an anode (12) which are communicated with each other are respectively embedded in the drainage layer and the planting layer; landscape plants are planted in the planting layer (10) and a humidity sensor (13) and a perforated buried irrigation pipeline (14) are buried in the planting layer; the perforated buried irrigation pipeline (14) is communicated with a submersible pump (15) at the bottom of the reservoir (7). According to the modular green roof system, high-efficiency regulation and control of nitrogen and phosphorus can be realized through modularization reconstruction of the green roof.

Description

technical field [0001] The invention relates to the application of green roofs in the construction of green buildings and sponge cities, in particular to a practical modular green roof system. Background technique [0002] Green roof is one of the commonly used technologies in green building and sponge city construction. Green roofs do not occupy additional land for urban construction. They have many advantages such as energy saving, increasing urban green space, reducing urban heat island effect, high efficiency in reducing runoff, and high efficiency in regulating nitrogen and phosphorus pollution loads. They have been more and more widely used in urban construction. [0003] At present, traditional green roofs are generally constructed by covering the roof with soil on site. On the one hand, this method has high construction costs, complicated construction process, high requirements for the top floor, and complicated operation and maintenance in the later stage; Landsca...

Problems solved by technology

On the one hand, this method has high construction costs, complicated construction process, high requirements for the top floor, and complicated operation and maintenance in the later stage; landscape requirements

In the process of green roof application, it is also found that the traditional green roof construction method is prone to secondary release of nitrogen and phosphorus. Sufficient retention has become an important issue facing the current development of green roofs
