Detailed Description

The embodiment is as follows: referring to fig. 1, a roadbed structure around a street tree comprises a tree root pool 14, curbstones 5, a motor vehicle lane 15, a non-motor vehicle lane 20 and a pedestrian path 16; the tree root pool 14 is arranged below the pedestrian walkway 16, the curbstone 5 is arranged between the non-motor vehicle lane 20 and the pedestrian walkway 16, and the motor vehicle lane is tightly attached to the non-motor vehicle lane; the tree root pool 14 comprises two symmetrical semi-trapezoidal concrete structures, and the two symmetrical semi-trapezoidal concrete structures are connected through butterfly-shaped buckles 6 to form the tree root pool 14 for containing tree roots of a street tree.

In this embodiment, the semi-trapezoidal concrete structure has a plurality of dovetail openings 19 with the same size as the butterfly-shaped buckles, and the dovetail openings are connected through the butterfly-shaped buckles 6. The butterfly-shaped buckle 6 is high in connection strength and convenient to install.

In this embodiment, the butterfly-type buckle includes a butterfly body 61 and butterfly wings 62 connected to both sides of the butterfly body.

In this embodiment, the butterfly wing 62 is a side-mounted trapezoidal shaped snap. The two sides of the butterfly body 61 are integrally connected with the upper bottom of the trapezoidal elastic buckle which is placed laterally.

In this embodiment, the sidewalk is provided with a ground masonry 9, a cement mortar bonding layer 10, a concrete layer 11, and a miscellaneous soil backfill layer 12 from top to bottom.

In the embodiment, the motor vehicle road is provided with an asphalt layer 1, a concrete base layer 2, a ballast layer 3 and a miscellaneous soil layer 4 from top to bottom.

In the present embodiment, the curbstone 5 is attached between the non-motor vehicle lane 20 and the pedestrian walkway 16, the lower part of the curbstone 5 is fastened 20cm below the road asphalt layer 1, and the upper part of the curbstone 5 is at the same height as the pedestrian walkway floor masonry 9.

In this embodiment, the upper part of the root pool 14 is a rectangular opening 7. The upper opening is favorable for rainwater and summer irrigation water to deeply enter the ground to supply nutrients for root systems of the tree roots to ensure the normal growth of the tree.

In this embodiment, the lower portion of the root pool 14 is an opening 18. The lower opening is convenient for guiding the root system of the tree to freely grow downwards, so that the tree can grow well.

Specifically, referring to fig. 3 and 4, the trapezoidal concrete tree pool can be divided into a left half trapezoidal concrete tree pool and a right half trapezoidal concrete tree pool which are symmetrical left and right, and can be separated during transportation, so that the transportation is convenient; during construction, the position of planting trees on the street trees is determined, a half of the trapezoidal concrete structure is placed into the dug tree pit to wrap the tree root, the other half of the trapezoidal concrete structure is placed into the dug tree pit to wrap the tree root, the tree root is wrapped and closed, and the inner walls are spliced to form a tree root pool for containing the tree root of the street trees.

Referring to fig. 2 and 5, the semi-trapezoidal concrete structure is provided with a dovetail port 19 which is connected by a butterfly-shaped buckle 6, and the two symmetrical semi-trapezoidal concrete tree ponds are provided with butterfly-shaped buckles which comprise a rectangular elastic butterfly body 61 and butterfly wings 62 on two sides of the butterfly body.

The tree root pool 14 is divided into a left half-trapezoid structure and a right half-trapezoid structure which are spliced, a plurality of dovetail ports 19 with large inside and small outside are correspondingly arranged on the splicing edges, the splicing is embedded by butterfly-shaped buckles 6 corresponding to the dovetail ports, and the two ends of each butterfly-shaped buckle are large and the middle is small.

Referring to fig. 1, after the trapezoidal concrete tree pool is spliced, the structure of the pedestrian path is firstly made into a miscellaneous soil backfill layer 12, a concrete layer 11, a cement mortar bonding layer 10 and finally ground masonry 9 from bottom to top. The structure of the motor vehicle lane is from bottom to top, wherein a miscellaneous soil layer 4, a ballast layer 3, a concrete base layer 2 and an asphalt layer 1 are manufactured firstly.
