A method for planting large trees on the roof of an underground garage

Abstract

The invention discloses a large arbor planting method suitable for a top plate of an underground garage. The method comprises the following steps of: S1, performing waterproof and puncture-stopping construction; S2, covering backfill planting soil; S3, placing arbors on the planting soil and supporting the arbors; S4, piling up soil compressing bags layer by layer by taking a region encircled by a supporting device as a boundary, wherein a layer of planting soil is backfilled once a layer of soil compressing bags is piled up to a designed elevation; and S5, removing or damaging the soil compressing bags from the bottom layer and backfilling the planting soil layer by layer. The method disclosed by the invention can effectively avoid damage on underground pipelines and a waterproof puncture layer in the planting process.

Description

technical field [0001] The invention relates to the field of arbor planting, in particular to a method for planting large arbors on the roof of an underground garage. Background technique [0002] In large and medium-sized cities, in order to use expensive land as efficiently as possible and expand the number of parking spaces, many residential areas have built large-scale basements. In order to ensure the greening rate of the residential area, it is usually necessary to cover the basement roof with backfill soil and then plant plants for landscaping. At present, the planting of large trees on the roof of the basement structure includes the following steps: Step 1: Waterproof and puncture-proof construction such as figure 1 As shown, the waterproof and puncture-proof layer construction is carried out on the roof of the basement structure to form a roof waterproof layer 2, a cement mortar protective layer 3, a drainage layer 4, an isolation filter layer 5, and a puncture-pro...

AI Technical Summary

Problems solved by technology

[0008] (1) Later arbor transportation and other work will greatly interfere with the backfill: when the backfill is completed and the arbor is planted in the later stage, it is often necessary to use machinery to transport the arbor, support, and backfill the planting soil. Due to the heavy weight of the mechanical equipment, it is easy to produce excessive Large pressure, the backfill soil is not as compacted as the natural subsidence soil after backfill, and it is easy to be squeezed and deformed, causing damage or interference to the small terrain formed by the backfill, and a second backfill is required after the arbor is planted, wasting manpower and material resources;

[0009] (2) Excavating planting pits is likely to cause damage to underground pipelines: the planting of large trees is generally carried out after pipeline projects, such as irrigation water pipelines and landscape equipment power pipelines, are completed

[0011] (4) The depth of the arbor auxiliary support is insufficient, and the support effect is limited: in order to prevent the damage to the waterproof layer and the anti-puncture layer caused by the excessive depth of the support, the depth of the general arbor support is only about 0.5 meters.

In strong typhoon weather, it is easy to cause the arbor to fall due to insufficient support depth;

[0012] (5) Backfilling planting soil is prone to defects: after the arbor is planted, the amount of backfilling planting soil is small and only exists in the planting pit, which limits the later growth of the arbor and prevents the arbor from achieving the best landscape effect

In addition, due to the limitation of the planting pit wall during the backfilling process, it is difficult to tamp the planting soil, and it is easy to settle during the later maintenance process, requiring secondary soil filling;

[0013] (6) The root system of the tree is easy to damage the waterproof and puncture-proof construction: as the tree grows, its root system can easily penetrate and destroy the waterproof and puncture-proof construction, resulting in a shortened service life of the waterproof and puncture-proof layer
