[0002] In the construction of landscaping, it is necessary to transplant and transplant the original seedlings in the shaping area, and then restore the seedlings after the earthwork is cleaned, leveled, improved, and shaped. If transplantation and transplanting are not performed, the backfilled earth will cover part of the tree trunk, and the backfill height may reach about 1m. The backfilling of earth will affect the normal growth of the seedlings and even cause the death of the seedlings. Since transplantation and transplanting will cause a certain degree of damage to the roots, branches and leaves of the seedlings during the operation, it will lead to problems such as slow recovery of the seedlings after planting, cumbersome maintenance and management, and poor landscape effects.

[0019] The technical solution of the utility model is further described below in conjunction with specific implementation methods:

[0020] A high fill protection structure for seedlings in situ includes a partition wall 1, a breathable water-retaining layer 2, and a protective layer 3. This embodiment takes slope construction as an example. Figure 1As shown, shaping earth is covered on top of the original soil layer 4 where the roots of the seedlings are located, so that part of the tree trunk will be buried in the shaping earth 5. In this embodiment, the isolation wall 1 is installed on the outside of the trunk of the existing seedling, and a cavity is formed in the isolation wall 1. The shaping earth 5 is filled on the outside of the isolation wall 1, and the shaping earth 5 and the trunk are separated by the isolation wall 1; the cavity formed by the isolation wall 1 is vertically arranged, and the cavity extends upward to be flush with the shaping earth 5, and the trunk passes through the cavity.

[0021] The breathable water-retaining layer 2 is filled in the cavity. When water enters the cavity from the upper end of the cavity, part of the water seeps into the original soil layer 4 and is absorbed by the roots, and part of the water is absorbed and stored in the breathable water-retaining layer 2, thereby avoiding water accumulation in the cavity, causing root hypoxia and the production of organic acids and other substances, and preventing the tree trunks from being soaked in water and causing mildew and rot. In addition, due to the backfilling of the modeling earthwork 5, the roots of the seedlings move downward relative to the ground surface, and the moisture situation at the roots cannot be observed. The water on the surface can enter the cavity, and the breathable water-retaining layer 2 can store part of the water. When the roots are short of water, the water stored in the breathable water-retaining layer 2 can be released to provide water to the roots, thereby avoiding water shortage at the roots.

[0022] The breathable water-retaining layer 2 is filled along the original soil layer 4 at the bottom of the cavity to near the upper end of the cavity. A protective layer 3 is arranged above the breathable water-retaining layer 2 in the cavity to prevent the breathable water-retaining layer from escaping from the cavity. The protective layer 3 is a water-permeable and breathable protective layer, and external rainwater can enter the cavity through the protective layer 3.

[0023] The air-permeable water-retaining layer 2 includes a plurality of granular spheres, each granular sphere having a plurality of water-absorbing pores, and a plurality of gap channels formed between the granular spheres, which can not only realize the function of absorbing and storing water, but also ensure the air permeability in the cavity. In this embodiment, the granular spheres are such as perlite particles, and the protective layer 3 is such as a planting soil layer, which confines the perlite particles in the cavity and can also ensure the air permeability and water permeability in the cavity.

[0024] As a preferred method, the planting soil layer is a peat soil layer with a thickness of 80-100 mm. Peat soil is soft and breathable but has weak water retention, which can ensure that water can penetrate into the cavity.

[0025] The planting soil layer fills the cavity flush with the modeling soil 5, and the planting soil layer and the modeling soil 5 are respectively covered with a soil consolidation layer, such as turf 6, which can achieve both soil protection and aesthetic purposes. Peat soil has a high organic matter content, which can slowly release a large amount of trace elements for the growth of turf, ensuring the growth of turf.

[0026] In another embodiment, the protective layer may also be a mesh structure, such as a wire mesh, which is tied and fixed to the upper edge of the partition wall.

[0027] The partition wall 1 includes an outer supporting structure layer 7 and a waterproof layer 8 arranged inside the supporting structure layer 7. This embodiment provides a form of a partition wall, such as Figure 2 As shown, the supporting structure layer 7 has a uniformly arranged corrugated structure 9, and the waterproof layer 8 is arranged in contact with the inside of the supporting structure layer 7, and a number of annular air chambers are formed between the corrugated structure 9 of the supporting structure layer 7 and the outer surface of the waterproof layer 8. The corrugated shape increases the strength of the partition wall, and at the same time can ensure that the partition wall has a certain toughness and is not easy to crack under the pressure of the outer modeling earthwork. In this embodiment, the partition wall is made of high-density polyethylene (HDPE). When in use, the partition wall is first cut to facilitate the tree trunk to enter the cavity from the side of the partition wall, and then the cut position is fixed by tying strips, steel wires, hoops, etc., and waterproof glue can also be applied to the cut position for bonding.

[0028] This embodiment also provides a form of a partition wall, such as Figure 3 As shown, the side wall of the partition wall 1 is provided with an opening for the tree trunk to enter the cavity, the opening extends from one end of the cavity to the other end, and an interface for the opening to be matched is provided at the opening, such as a mortise and tenon interface, and the mortise and tenon interface is connected. The partition wall is elastic, and the opening can be enlarged to facilitate the entry of the tree trunk. The material of the partition wall is a high-density polyethylene material (HDPE). In order to increase the tightness of the interface, sealant can also be applied to the mortise and tenon interface, and hoops, steel wires, etc. can be added to the outside of the partition wall for reinforcement.

[0029] This embodiment is only a further explanation of the utility model, not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the scope of the claims of the utility model, it will be protected by the patent law.
