How to make the green roof of municipal landscape design not a violation?

The green roof of the building should be planted with plants that are resistant to sunlight and cold, do not need too much water, and have not deep roots. The plant species of roof greening generally choose low shrubs, ground covers, perennial flowers, vines, etc. In principle, tall trees are not used.

In order to prevent plant roots from penetrating the waterproof layer of the building, plant varieties with developed fibrous roots should be preferentially selected for roof greening, rather than plants with straight roots or plants with strong root puncture.

Roof greening should consider the load-bearing problem of the roof. It's a matter of security. The load-bearing capacity of the building is limited by the load-bearing capacity of the beams, slabs, columns, foundations and foundations under the roof garden (greening).

Because the bearing capacity of the building structure directly affects the level of the house cost, the allowable load of the roof is limited by the cost, and can only be within a certain range, especially when the roof greening is carried out for the original building without roof design, more attention should be paid to the allowable load of the roof.

In this way, the average load of the roof garden (greening) can only be controlled within a certain range. To solve this problem, substrate cultivation should be employed. Such as:

When using soilless lawn for roof greening, the amount of substrate can be adjusted as needed to replace the loam layer of the same thickness required for roof greening, so as to greatly reduce the load bearing of the roof.

Leakage should be considered for green roofing. Due to the long-term wetness under the vegetation, and the corrosive effect of acid, alkali and salt, it will cause long-term damage to the waterproof layer. At the same time, the roots of roof plants will invade the waterproofing layer, damaging the roof structure of the house, causing leakage.

Another difficulty in the leakage prevention of the roof garden is that the roof is covered with soil and greenery, and if it leaks, it is difficult to find the leakage point.

Maggi's roof greening should focus on design issues. First, the special requirements of roof greening should be considered in the architectural design, such as: roof load-bearing, roof leakage, lighting, water supply and drainage, leakage prevention, etc. Second, the design of the roof garden should be adapted to local conditions.

The area of the roof garden is not large, and it is necessary to combine sculptures, garden paths, lights, pools, fountains, flowers and trees, pavilions, architectural styles and other exquisite combinations within the limited roof area.

First, the roof can definitely be planted with greenery, which can purify the air and increase oxygen; Thermal insulation in winter, heatstroke prevention in summer, and carbon emission reduction may be the direction of building development in the future.

Second, the greening method:

1. It can be very luxurious, laying drainage, water supply pipelines, and then laying soil, and even fully automated, rockery and fake water, and making it into a garden.

2. It can also be adapted to local conditions, and local flower and tree ponds can be built to fill the soil and plant flowers and trees. But no matter what the method, the first thing is to do a good job of roof leakage, and the second is to facilitate drainage.
