Basement roof cinnamomum camphora planting method

Abstract

The invention relates to the technical field of garden engineering, in particular to a basement roof cinnamomum camphora planting method. The planting method comprises the following specific operationsteps that backfill is designed according to a heaped slope, a layer of geocells are arranged in a cinnamomum camphora planting area, the mesh geocells in a tree hole digging area are cut off, and atree hole is dug; and geotextile and geogrids are arranged in the tree hole, the geotextile is laid at the bottom of the tree hole, landfill of light soil with the thickness of 20-30 cm is carried out, cinnamomum camphora is placed in the tree hole and covered with filled soil, mixed soil is added after soil filling is completed, wood piles are used for fixing, and the wood piles are fixed to thegeocells close to the wood piles through straw ropes. It is guaranteed that soil balls are stable when the cinnamomum camphora is subjected to heaped slope planting on a basement roof with thin backfill soil, slope surface collapse caused by flowing water scouring or slope top collapse caused by slope bottom soil loss is avoided, the heaped slope stability is guaranteed, the landscape attractiveness is improved, a guarantee is provided for the structure of over-excavating the tree hole and replacing the light soil, the water permeability of the bottom of the cinnamomum camphora tree hole is indirectly improved, and the survival rate is increased.

Description

technical field [0001] The invention relates to the technical field of landscape engineering, in particular to a method for planting camphor on the roof of a basement. Background technique [0002] In the greening of the community, the planting technology above the basement roof has always been one of the difficult problems to solve. Since the basement roof is close to the ground level, the roof bearing capacity and impermeability of the roof are limited, and it is difficult to plant large trees on the roof. In addition to the need There is a good drainage cushion and load distribution structure, and the tree hole is deep enough to accommodate the arbor soil ball. The most difficult thing is the planting of camphor. Generally, the size of camphor is relatively large, and the soil ball is also relatively large. However, the elevation between the basement roof and the backfilling surface is relatively small. In order to meet the drainage requirements, the bottom of the camphor...

Problems solved by technology

The most difficult thing is the planting of camphor. Generally, the size of camphor is relatively large, and the soil ball is also relatively large. However, the elevation between the basement roof and the backfilling surface is relatively small. In order to meet the drainage requirements, the bottom of the camphor hole often needs to be replaced with light soil. The thickness of the backfill soil cannot meet the planting requirements. At present, the main solution is to plant on slopes. Since camphor plantation requires soil with good air permeability, the soil has a high sliding property, and places with large slopes will collapse under the erosion of rainwater.

[0003] Install geocells on the pile slope, and use the lateral confining force of the geocells to prevent soil displacement. This method has a better effect in the short term, but long-term rain erosion will cause the underlying soil to move, resulting in the collapse of the pile slope. Happening
