Novel combined type roof greening tank with communication of matrixes

Abstract

The invention discloses a combined type roof greening tank which is suitable for roof greening and can maintain the communication of matrix layers. The combined type roof greening tank comprises a water storage and drainage bottom plate, a surrounding plate and a water absorbing carpet, wherein the water storage and drainage bottom plate and the surrounding plate are respectively made by punching HDPE (high density polyethylene) plastic rubber bottom plates. The combined type roof greening tank has the advantages that the water storage space of the water storage and drainage bottom plate is large, the water distribution is uniform, and the water drainage is smooth; lower surrounding ridges and reinforcing ribs are arranged around the plate surface of the bottom plate; the bottom plate is provided with connecting bayonest, and can be combined and spliced with other bottom plates; the surrounding plate can be installed or detached according to requirements, and can be repeatedly used; after multiple tank bodies are spliced, the surrounding plates are plugged out, so that the planted matrixes can be connected into a whole, plant roots obtain open development space, and the development space is favorable for plants to survive and grow; the appearance is not blocked, and more attractiveness is realized; during removal or detachment, the surrounding plate is inserted into a corresponding position again, so as to facilitate handling; the water absorbing carpet is formed by crushing and pressing recycled cloth, a water absorbing belt is arranged under the water absorbing carpet, and water can be supplemented into the matrixes from bottom to top.

Description

technical field [0001] The invention belongs to the field of building greening engineering and relates to a novel combined substrate-connected roof greening box. Background technique [0002] With the rapid development of urbanization, impermeable materials cover the urban land, leading to the urban heat island effect, urban waterlogging is becoming more and more serious, and the contradiction between green land and urban construction land is increasingly intensified. In order to maximize the accumulation, infiltration and purification of rainwater in urban areas, the state and local governments have successively issued opinions and methods for the construction of "sponge cities" that promote the utilization of rainwater resources and ecological environment protection. Roof greening will transform desertified roofs, which occupy a considerable proportion of the city, into green spaces. While retaining rainwater, slow drainage and slow release, it will also play a role in ene...

Problems solved by technology

[0004] However, in the current related technologies, the usual box body is too simple, and the water storage capacity is insufficient to meet the needs of plants, and the survival rate of plants is low; when storing water, some water storage cups are full and overflow, and some have not yet collected rainwater; , some of the water storage cups have dried up, and some of the water storage cups have not been fully utilized

Some need to set up additional water tanks, which requires high load-bearing capacity of the roof structure and increases the cost

The on-site construction process is complicated, maintenance is inconvenient, the construction period is increased, construction waste may appear, and labor costs and time costs are high

The product has poor adaptability and cannot meet the needs of roof greening with different substrate thicknesses and shapes

Each box is blocked by the box wall, which affects the appearance and makes the matrix disconnected, and the habitat of the plants is fragmented. Some plants need to be transplanted on site, which is not conducive to the growth and survival of the plants.
