Green roof system

Abstract

The invention discloses a green roof system that makes full use of such clean energy as solar energy, wind energy and the like, saves water resource, and is energy-saving, environment-friendly, good in the whole comprehensive energy saving effect as well as in waterproofness, easy for maintenance and long in service life. The roof system comprises a roof (1), a plant layer (4), a drain tank (31), a circulating water tank (32), a water supply irrigation pipeline (33), a circulating water pump (36), a solar power generation device (6), a wind power generation device (7), an electrical control cabinet (80) and an accumulator battery (81). The roof (1) is covered with a stainless steel waterproof layer (2) with all-welded seam. The plant layer (4) is on the stainless steel waterproof layer (2). A water outlet of the drain tank (31) is connected into the circulating water tank (32). The inlet of the circulating water pump (36) leads to the circulating water tank (32) and the outlet is connected with the water supply irrigation pipeline (33). A water replenishing pipeline (37) and an evacuation pipeline (38) are connected on the circulating water tank (32). The green roof system can be widely applied to the green building field.

Description

technical field [0001] The invention relates to a building roof system, in particular to a green roof system. Background technique [0002] In recent years, with the development of the concept of green environmental protection, more and more attention has been paid to green roofs, and green buildings have gradually emerged. Urban roof greening is one of the most effective ways to improve the urban climate, and it is an environmental project with low investment and quick results. Green roof refers to the greening on the top of various buildings, structures, etc., as well as on the roof and terrace above the ground and the surroundings are not connected with the natural soil layer. The benefits of the green roof system are many: it can effectively increase the area of ​​the garden green space, expand the green space, promote the ecological balance of the city, optimize the living environment, meet the needs of people to get close to nature and return to nature, and it is also...

AI Technical Summary

Problems solved by technology

[0003] The existing green roof system is to lay a waterproof layer of rolled materials such as plastic on the roof, and then cover the planting layer on the waterproof layer. This kind of green roof system is relatively simple, and has not fully utilized clean energy such as solar energy and wind energy. Taking into account the recycling of water, that is, not considering the overall effect of comprehensive energy saving

In addition, this structure has the following disadvantages: the sealing of the seams between the waterproof layer membranes is not reliable, and it is easy to cause water to leak from the seams to the roof; in addition, when the planting layer is covered, the waterproof layer may also be damaged. And produce water leakage; the root system of the plant growth process may also damage the plastic waterproof layer and cause leakage. Once this traditional green roof system leaks, it will be difficult to find out the leakage point and difficult to repair , may eventually require remaking the entire green roof system, which is quite expensive to maintain
