Description

[0002] At present, to meet people's living needs, large-scale, large underground garage structures are becoming more and more common in the construction industry. This is especially true in large residential communities, large office buildings, and other projects. Almost all underground spaces are used as garages and equipment rooms, and fire lanes, landscaping, pedestrian walkways, etc. need to be constructed on the roof of the underground garage. At the same time, the planting of seedlings in the landscaping needs to be considered. For example, the planting of large trees should be given more attention. In the past, in tree planting, especially in underground garage roofs, the bottom of the tree planting hole was impermeable. In the summer, heavy and rapid rainfall can easily cause waterlogging in the tree planting hole, which in turn causes the tree's root system to rot and die.

[0003] According to the requirements, if the tree planting mortality rate exceeds a certain level, the dead seedlings must be replaced free of charge, which will result in huge additional costs. To change this situation, we will increase the survival rate of tree planting and reduce the occurrence of additional costs.
