Description

Technical Field

[0001] The invention relates to the technical field of urban greening construction, and in particular to a roadside tree pool filling protection construction method. Background Art

[0002] It has become a development trend to plant trees on the sidewalk to beautify the road, provide shade, reduce noise, and purify the air. At present, in the process of planting trees, the tree pit is usually excavated after the sidewalk is paved. After the tree pit is excavated, the anti-seepage geotextile is laid, and then the green soil is backfilled with a loader and the trees are planted. However, in the process of backfilling the green soil, it is easy to cause the green soil to overflow the tree pit, which will cause secondary pollution to the curbstones and walkway bricks that have just been constructed, which is not conducive to cleaning and protection of finished products. In addition, in the process of backfilling the green soil, the impact force is large, which is easy to cause the geotextile to be damaged and fall off, which is not conducive to later anti-seepage and seedling survival. Summary of the invention

[0003] In view of the above problems, an embodiment of the present invention provides a roadside tree pit filling protection construction method.

[0004] One aspect of the present invention provides a roadside tree pit filling protection construction method, comprising:

[0005] After the tree pit is excavated and the geotextile is laid, the main body of the protective device is designed and manufactured according to the size of the top opening of the tree pit. The inner edge contour of the main body of the protective device is adapted to the top opening of the tree pit.

[0006] Fix the prepared protective device body at the edge of the top of the tree pit, press the geotextile tightly, and fix the enclosure on the outer edge of the protective device body;

[0007] A buffer baffle is hinged relatively on the inner edge of the protective device body, and the buffer baffle is in a double-door structure. When the buffer baffle is closed, the top pool opening of the tree pool can be closed;

[0008] After the buffer baffle closes the top of the tree pit, a loader is used to backfill the green soil. During the backfilling process, the buffer baffle is pressed down by the weight of the green soil itself, so that the buffer baffle is closely attached to the geotextile at the side wall of the tree pit. During the backfilling process, the buffer baffle plays a role in buffering the green soil and protecting the geotextile.

[0009] After the greening soil is backfilled, it is leveled, and then tree holes are dug and street trees are planted in the tree holes.

[0010] Optionally, before planting the street tree in the tree pit, the method also includes: welding a lifting handrail on the enclosure, and using a lifting device to lift the main body of the protective device out through the lifting handrail.

[0011] Optionally, a positioning mark is relatively set on the center line of the protective device body. When the manufactured protective device body is fixed on the edge of the top of the tree pit and the geotextile is pressed tightly, the position of the protective device body is adjusted by the positioning mark so that the positioning mark is located on the center line of each tree pit.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the enclosure set on the main body of the protective device can reduce the secondary pollution of the surrounding structures during the backfilling of greening soil; the weight of the main body of the protective device is used to press and fix the geotextile, and a buffer baffle is set in the middle of the main body of the protective device to prevent the geotextile from being damaged by excessive impact during the backfilling of greening soil. In addition, the buffer baffle is pressed down and adheres to the surface of the geotextile, which protects the geotextile; finally, the positioning marks can be set to ensure that all tree holes are in a straight line, so as to prepare for the later planting of street trees, ensure that the seedlings are planted in a straight line, improve the appearance and beauty, and reduce the later laying and straightening work. The overall construction device is easy to manufacture, easy to operate, and reusable. It has good economic and social benefits and a certain promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0022] See also Figure 1-Figure 6 The embodiment of the present invention provides a roadside tree pit filling protection construction method, comprising:

[0023] S100, after the tree pit is excavated and the geotextile is laid, the protection device body 1 is designed and manufactured according to the size of the top opening of the tree pit, and the inner edge contour of the protection device body 1 is adapted to the top opening of the tree pit.

[0024] In implementation, the shape of the protection device body 1 can be the same as the shape of the top opening of the tree pit. For example, if the top opening of the tree pit is rectangular, the corresponding protection device body 1 is a rectangular frame structure.

[0025] S110, fix the prepared protection device body 1 at the edge of the top of the tree pit and press the geotextile 7, and fix the enclosure 2 on the outer edge of the protection device body 1. The enclosure 2 set on the protection device body 1 can reduce the secondary pollution of the surrounding structure during the greening soil backfilling process.

[0026] During implementation, a positioning mark 4 can be relatively set on the center line of the protection device body 1. When the manufactured protection device body 1 is fixed on the edge of the top of the tree pit and the geotextile 7 is pressed tightly, the position of the protection device body 1 is adjusted by the positioning mark 4 so that the positioning mark 4 is located on the center line of each tree pit; the positioning mark 4 is set to ensure that all tree holes are located in a straight line, prepare for the later planting of street trees, ensure that the seedlings are planted in a straight line, improve the appearance and beauty, and reduce the later line laying and straightening work.

[0027] The positioning mark 4 can be made by cutting an iron plate into an isosceles triangle, and the height of the isosceles triangle coincides with the center line of the protective device body 1; four positioning marks 4 can be set in specific settings, two of which are on the length center line of the protective device body 1, and the other two are on the width center line of the protective device body 1.

[0028] S120, a buffer baffle 3 is relatively hinged on the inner edge of the protection device body 1, and the buffer baffle 3 is a double-door structure. When the buffer baffle 3 is closed, the top opening of the tree pit can be sealed.

[0029] During implementation, the buffer baffle 3 can be hinged on the protective device body 1 using the damping hinge 6 to achieve a buffering effect when the greening soil is backfilled.

[0030] S130, after the buffer baffle 3 closes the top of the tree pit, a loader is used to backfill the green soil. During the backfilling process, the buffer baffle 3 is pressed down by the green soil itself, so that the buffer baffle 3 is tightly attached to the geotextile 7 on the side wall of the tree pit. During the backfilling process, the buffer baffle 3 plays a role in buffering the green soil and protecting the geotextile 7.

[0031] During implementation, after the green soil is backfilled, the buffer baffle 3 is pressed down and closely adheres to the surface of the geotextile 7, thereby protecting the geotextile 7.

[0032] S140, after the greening soil is backfilled, it is leveled, and then tree holes are dug and street trees are planted in the tree holes.

[0033] During implementation, before planting street trees in the tree pits, the steps also include: welding a lifting handrail 5 on the enclosure 2, using a lifting device to lift the main body of the protective device through the lifting handrail, and then moving it to the next tree pit for construction.

[0034] By setting the enclosure 2 on the main body 1 of the protective device, the secondary pollution to the surrounding structures during the backfilling of greening soil can be reduced; the weight of the main body 1 of the protective device is used to press and fix the geotextile 7, and at the same time, a buffer baffle 3 is set in the middle of the main body 1 of the protective device to prevent the geotextile 7 from being damaged by excessive impact force during the backfilling of greening soil. In addition, the buffer baffle 3 is pressed down and tightly adheres to the surface of the geotextile 7, which protects the geotextile 7; finally, the positioning mark 4 can be set to ensure that all tree holes are located in a straight line, so as to prepare for the later planting of street trees and ensure that the seedlings are planted in a straight line, thereby improving the appearance and beauty and reducing the later line laying and straightening work.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
