The multi-year average rainfall in North China is the annual statistical hour. The maximum rainfall intensity is the maximum within the hour.
The maximum rainfall intensity is the multi-year average natural evaporation in North China. . Covering with green plants can effectively reduce evaporation
, especially shrub vegetation. Garage planting filter board/basement drain board/Langfang plastic drainage board manufacturer
Therefore, North China is an arid area where rainfall is far less than evaporation. For urban shallow basin green spaces, it is easy to form deep accumulation
The worst-case scenario of dry water on top of the water. The emergence of water storage and drainage boards has completely solved this passive situation. It not only solves the problem of deep water accumulation that cannot be drained, but also reduces the need for artificial evaporation in the north because evaporation is greater than rainfall. Cost of watering.
Generally, the saturated moisture content of soil is between ~. The water retention performance of soil depends on the soil type and thickness. The thicker the soil
the stronger its water retention function is. Garage planting drain board sales/Langfang plastic drainage board manufacturer Manager Liu
A well-greened ground can delay the surface runoff of natural rainfall for a long time, increase the infiltration of surface water, and the precipitation within the year is concentrated
Within a short period of time, a groundwater layer will still form on the roof of the underground garage. If there is no communication between the internal and external environment, the water level will gradually rise. When the groundwater level rises to a certain height, it will affect some aspects. The growth and even death of trees, shrubs and even flowers and plants. Garage planting filter board/basement drain board/Langfang plastic drainage board manufacturer Manager Liu
All plants have a certain ability to withstand waterlogging and will not die when completely immersed in a water environment in a short period of time. Most plants can
Communities that have withstood hours of waterlogging, but have no drainage layer to remove the deep water accumulation on the roof, causing the vegetation to wither and die
There is a trend of frequent occurrences (originally there are fewer underground garage roofs, and more Because of hardening, not enough attention was paid).
In the natural environment, the flow and circulation of groundwater rely on the natural flow and circulation of water by gravity. Therefore, if there are good drainage channels
the deep water seepage on the roof of the underground garage can rely on its own gravity. Realize natural circulation flow. Find the slope) layer
