How is the sunken courtyard designed? How about this sunken courtyard?

Sinking courtyard is one of the forms of courtyard space design under suitable site conditions. Because everyone has their own hobbies, they present different forms of activity space. For example, fully closed, fully open, semi-closed and semi-open. No matter what type of courtyard space is chosen, the sunken courtyard is generally drained by rainwater pipe network, which requires good greening and permeability of the courtyard. If there is a pond or reservoir in the yard, it can relieve part of the drainage pressure well, and it can also be used as a storage pond to kill two birds with one stone.

Now everyone attaches great importance to decoration. People in both urban and rural areas will decorate their homes beautifully, which is a very important issue for yard drainage. The following small series will introduce you to the main points of sinking courtyard drainage. Let's have a look! The advantage is that the first floor that is not easy to sell has become an expensive villa, while the underground has become a saleable property area. There is also an underground parking lot on the basement level, 1-2. So under this sunken courtyard are concrete floors and basements.

There are already supporting water supply and drainage facilities that meet the specifications. Moreover, this kind of space generally appears continuously and regularly in residential villas, and each sunken courtyard conforms to the specifications (considering courtyard area and precipitation). The drainage pipe is connected to the rainwater and sewage pipe network of the community, and then connected to the municipal wide area network. I think this is a very professional question. It is necessary to adjust measures to local conditions, tailor the hospital, or find a professional construction unit to carry out field survey and measurement, and then carry out professional design and construction, in order to achieve effective and efficient drainage. Don't blindly think that three or two sentences can solve the problem here. As an open sunken courtyard, it is most convenient to use Zede ufb200, a buried rainwater and sewage elevator. It is equipped with a leaky grid, which allows rainwater to be poured directly into the box without building too many pipes.
