Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of greening engineering, in particular to a breathable and water-draining device for planting large trees. Background Art
[0002] In the construction of greening projects, planting large trees is one of the key points of greening project management. The cost of seedlings accounts for a large proportion. Problems in construction and maintenance will lead to low survival rates of large trees and poor growth of seedlings. In order to ensure the survival rate of large trees, they are usually planted with soil balls, and measures such as gravel air permeable layers or perforated plastic pipes are set in the tree pool for ventilation and water drainage of the roots of seedlings. However, during the implementation of the above measures, the air permeability and water drainage properties of the roots are gradually lost because the soil particles flow when they encounter water and fill the air permeable channels. Greening management and maintenance personnel need to loosen the soil again, which is not conducive to the management and maintenance of large-scale seedlings. Utility Model Content
[0003] In order to solve the above problems, the utility model proposes a breathable and water-draining device for planting large trees.

The inner ends of the horizontal tube bodies are connected to each other, and the air permeable tubes form a seat structure for accommodating a soil ball. The horizontal tube body is horizontally placed at the bottom of the tree pit, the vertical tube body is close to the inner wall of the tree pit, and the vertical tube body extends upward from the tree pit.
[0005] Preferably, the surface of the air permeable tube is covered with a layer of geotextile.
[0006] Preferably, the air permeable tube is a plastic tube with side walls densely covered with water-permeable circular holes.

[0008] Preferably, a circular water collecting shell is provided between the inner ends of the air-permeable tubes, and the side of the water-collecting shell is evenly distributed with a plurality of through holes connected with the internal cavity thereof, and a plurality of air-permeable tubes are correspondingly inserted into the plurality of through holes to form a sealing structure with each other.
[0009] Preferably, the number of the vent pipes is at least five;
[0010] Preferably, the vertical tube extends about five centimeters above the ground.
[0011] The beneficial technical effects of the utility model are:
[0012] (1) The utility model forms an interconnected ventilation and drainage channel at the bottom of the tree pit through the ventilation tubes distributed in a circular pattern, thereby providing sufficient circulating air for the roots of the seedlings and draining the upper water to the lower part through the ventilation tubes, thereby reducing the risk of root rot and disease.
[0013] (2) The geotextile on the surface of the ventilation pipe of the utility model has a filtering effect, preventing soil particles from entering the ventilation pipe and avoiding affecting the air permeability and hydrophobicity of the drainage blind pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1, see the attached specification Figure 1-6 A breathable and water-repellent device for planting large trees is installed in a tree pit 61, and includes a plurality of breathable tubes 01 evenly arranged in a circle. The breathable tube 01 includes a vertically connected transverse tube body 11 and a vertical tube body 12. A bend transition is provided at the connection between the transverse tube body 11 and the vertical tube body 12. The inner ends of the transverse tube bodies 11 are connected to each other. The transverse tube bodies 11 are horizontally placed at the bottom of the tree pit 61, and the vertical tube bodies 12 are close to the inner wall of the tree pit 61. The soil ball 41 of the root of the seedling is placed between the breathable tubes 01, and the vertical tube body 12 extends upward from the tree pit 61.
[0022] The ventilation pipe 01 is a plastic pipe or drainage blind pipe with side walls densely covered with water holes 13. The plastic pipe or drainage blind pipe densely covered with water holes 13 is to make the ventilation pipe 01 have good water permeability.
[0023] The surface of the air pipe 01 is covered with a layer of geotextile 21 , which is used to prevent fine soil from clogging the holes on the surface of the air pipe 01 , and the geotextile 21 will not affect the water permeability of the side wall of the air pipe 01 .
[0024] A circular water collecting shell 31 is provided between the inner ends of the air tubes 01, and the sides of the water collecting shell 31 are evenly distributed with a number of through holes connected to the internal cavity 311 thereof. A number of air tubes 01 are correspondingly inserted into the number of through holes. The water collecting shell 31 is used to connect the various air tubes 01 and can also store some water.
[0025] The number of the air tubes 01 is at least five. The roots of the seedlings are concentrated in the soil ball 41. A larger number of air tubes 01 can ensure the air permeability and water-repellent effect of the air tubes 01 on the roots of the seedlings.
[0026] The vertical tube body 12 extends out of the ground by about five centimeters, which is convenient for exchanging air from the inside of the tree pit 61 to the outside, and water can be directly poured to the roots of the seedlings from the extended part.
[0027] The use process of the utility model is as follows: each air permeable tube 01 is firmly covered with a layer of geotextile 21, and then the air permeable and water-draining device is placed in the tree pit 61, and the seedlings are placed between the air permeable tubes 01 in the tree pit 61, and then the tree pit 61 is filled, and the upper end of the air permeable tube 01 extends out of the ground, and a circle of earthen ridge cofferdam 51 is surrounded on the outside of the tree pit 61. Each air permeable tube 01 forms an interconnected air permeable and water-draining channel at the bottom of the tree pit 61, providing sufficient circulating air for the roots of the seedlings, and can drain the upper water to the lower part through the air permeable tube 01, so that the water distribution at the roots of the seedlings is more even, effectively reducing the problems of root rot and disease.
