Greening device used at roof of urban building

Abstract

The invention relates to the technical field of greening engineering, in particular to a greening device used at a roof of an urban building. The greening device comprises a U-shaped case, wherein a cultivation box is clamped in a groove cavity in the middle of the U-shaped case; two water seepage pipes are arranged at the left side and the right side at the bottom of the cultivation box, a soil bottom-layer cavity board is arranged at the bottom in the cultivation box, partition boards are correspondingly arranged on the left side and the right side on the soil bottom-layer cavity board, and the partition boards are vertical to the soil bottom-layer cavity board; rainwater collection boxes are correspondingly arranged at the left side and the right side of the top of the U-shaped case, water outlets are both arranged in the bottoms of the inner lateral surfaces of the rainwater collection boxes, each water outlet is connected to a water pipe, and the two water pipes are respectively arranged on the left lateral surface and the right lateral surface in the cultivation box; a plurality of permeation holes are formed in each water pipe. The greening device has the advantages of simple structure, low cost and capability of collecting rainwater to meet daily water supply requirement for greening plants at the roof of the building.

Description

technical field [0001] The invention relates to the technical field of greening engineering, in particular to a greening device for urban building tops. Background technique [0002] With the development of social urbanization, people are more and more concentrated in the city, so various apartment buildings have been built one after another, encroaching on the green area of ​​the city. Therefore, how to add green for people on the roof or around the buildings in the city, or in some communities with poor greening projects. Traditional urban buildings add greening projects on their roofs, generally a large amount of soil is set on the roof, and then green plants are planted on it. This structural method has the following problems: first, due to the increase of a large amount of soil on the roof, the load-bearing of the building is increased, and there are potential safety hazards, and the structure needs to be strengthened on a large scale, which increases the maintenance c...

Problems solved by technology

This structural method has the following problems: first, because a large amount of soil is added to the roof, the load-bearing of the building is increased, and there are potential safety hazards, and the structure needs to be strengthened on a large scale, which increases the maintenance cost; the second is the roof. The water resistance of the roof increases the hidden danger of water leakage on the roof, which also increases the cost of maintenance; the third is that when it rains, the water cannot be locked, so it is necessary to irrigate the plants from time to time, which is troublesome and inconvenient. job difficulty
