Description

Soil support unit and soil support device

The present invention relates to a soil supporting unit and a soil supporting device, and more particularly to a soil supporting unit and a soil supporting device which are laid under the surface of the ground and provide a good stretching space for the roots of the trees planted on the ground.

At present, the surface layer composed of cement, tar and pebbles or floor tiles laid on the soil layer, due to insufficient water permeability of the surface layer, it is difficult for rainwater to pass through the surface layer of the ground to the soil layer below, and rainwater is likely to generate water on the ground. Flooding; in summer, the sun is shining, and the moisture in the soil layer is also difficult to evaporate through the surface layer to cause the ambient temperature to drop.

In order to solve the problem of insufficient water permeability of the ground surface layer composed of cement, tar and pebbles or floor tiles laid on the soil layer, some people use the soil support device to lay flat on the base layer of the construction, and then tiling on the soil support structure. The surface layer of the ground is used to extend the permeable hole in the soil supporting device to the ground, so that the rainwater falling on the ground can flow into the underlying basal layer through the permeable hole of the soil supporting device, and on the other hand, the water oozing into the soil layer The ambient temperature can also be lowered by evaporation through the permeable holes.

However, the existing soil support device provides poor drainage performance, resulting in a slower permeation rate of the base layer under the ground, so that the rainwater falling on the ground is still difficult to effectively penetrate into the soil layer under the ground through the soil support device.

Secondly, trees have other infrastructures that can beautify the city, regulate the climate to alleviate the urban heat island effect, absorb urban air pollution, purify the air, supplement oxygen, improve people's living environment, prevent soil loss, manage and purify rainwater, and improve property value. As an alternative function, urban trees are considered to be an important part of green infrastructure and the main means and content for urban greening.

When trees are used as the infrastructure for urban greening, most of the urban trees are usually planned to be set up in narrow areas due to the urban planning land planning. Therefore, only small holes can be planted, and pedestrian pavements are often set around the planting area. Traffic space such as roads or city roads. Therefore, the soil in the traffic area around the planting trees is compacted by the regular pressure, and the soil around the tree hole is compacted.

However, the narrow tree hole and the compacted tree hole soil are the main factors hindering the growth of trees, which often cause the tree to grow poorly, and the roots of the tree can not absorb the oxygen and water nutrients, which leads to the problem of limited tree growth and degradation. These problems are more serious in traffic spaces such as parking lots, impervious pedestrian pavements, or urban roads.

In addition, dig a small hole to plant trees, it will make the roots of the trees difficult to stretch, and the roots of the trees will not be able to penetrate the hard surface of the hard-skinned ground surface outside the tree hole, which will cause floating roots, often leading to paving of pedestrian walkways. Arching and destruction of the floor or pavement surface. It not only causes damage to road facilities, but also affects the street landscape. On the other hand, the floating roots of the roots of the trees can also cause problems such as slow tree growth, poor root development, and shallow roots, so that the roots of the trees are on the soil layer. The grip is weakened. When an abnormal weather such as a typhoon or heavy rain occurs, the trees are easily uprooted and dumped. The dumping of trees will damage the surrounding buildings, vehicles or public facilities, and pose a hazard to people's lives.
