Abstract

The invention discloses a sidewalk tree planting method for guiding tree roots to grow downwards by cement slabs, and relates to the field of tree planting, in particular to sidewalk tree planting. Root systems of trees are developed, and roots of sidewalk trees often damage a pavement to stumble pedestrians, particularly children and the old. When a tree is planted, hoisting equipment is used to put four trapezoidal cement slabs at positions 75 cm away from the trunk in a mode that long sides are positioned below and the short sides are positioned upwards, the four trapezoidal cement slabs are close to each other to encircle the tree and are buried in soil 30cm away from the soil surface; and a rectangular cement slab is vertically arranged on each trapezoidal cement slabs, is buried in the soil by 30cm and extends out of the ground by 50cm to provide a sitting place for the pedestrians. The trapezoidal cement slabs are inclined, so after the tree roots reach the cement slabs, the tree roots tend to grow downwards under the blockage of the cement slabs and are prevented from extending towards the pavement and jacking up paving bricks or cement blocks on the pavement to avoid influencing the flatness of the pavement, so that the potential safety hazards are avoided when the pedestrians walk.

Description

The pavement tree tree-planting method of cement plate guiding tree root growth downwards

Technical field

The present invention relates to the field of planting of trees, particularly the plantation of pavement tree.

Background technology

Tree root is flourishing, pavement tree tree root often occurs and destroys the road surface, makes intact road surface become uneven, causes pedestrian, particularly child and old man to trip and meets accident.

Summary of the invention

For overcoming the destruction of pavement tree tree root to the road surface, pavement, the present invention designs a kind of cement plate and promotes tree root to underground growth.

The technical scheme that the present invention solves its technical problem employing is: arrange that four upper ends are near from trunk, trunk trapezoidal cement plate far away is left in the lower end; The tree root growth touches cement plate; Because the tree root of this moment must be more immature, be not enough to contend with heavy cement plate, self-heating can only be crooked; Tree root mean level or growth downwards, the tree root propensity of running into cement plate is in wide-angle, just to darker underground growth.

The invention has the beneficial effects as follows: tree root reduces the damage to ground to underground growth, reduces security incident; Reduce the expense that safeguard on the road surface; Cement plate can partly elevate above the soil and supply the usefulness of pedestrian's rest.

Description of drawings

Fig. 1 is the pavement tree cement plate sketch map that tree-planting method adopted of cement plate guiding tree root growth downwards.

Wherein, 1, the rectangle cement plate, 2, lifting hole(eyelet), 3, trapezoidal cement plate.

Embodiment

Rectangle cement plate 1 size is: long 150cm, high 80cm, thick 10cm.

Trapezoidal cement plate 3 sizes are: the long 150cm of minor face, long length of side 300cm, high 150cm, thick 10cm.

Lifting hole(eyelet) 2 sizes are the circular hole of diameter 5cm, and the purpose of lifting hole(eyelet) is to overlap usefulness wherein with rope when supplying crane gear to shift out and install, and helps installing and maintenance in the future.

When planting trees, with the minor face of four trapezoidal cement plates 3 be placed on apart from trunk 75cm, four long limits of trapezoidal cement plate down, minor face last, draw close each other, be trapped among tree around, bury apart from earth surfaces 30cm; On each trapezoidal cement plate 3, vertically place a rectangle cement plate 1 then, rectangle cement plate 1 has that 30cm is embedded in the soil, 50cm elevates above the soil, and supplies the be seated usefulness of rest of passerby.

Because the inclination of trapezoidal cement plate; After tree root grows into cement plate, under the stopping of cement plate, tree root will tend to the less angle growth of resistance; I.e. growth downwards; Avoid tree root to stretch to pave the way brick or the cement block jack-up of road surface, influence the smooth of road surface, reduce the risk that passerby's security row walks to bring hidden danger the road surface.

Claims

1. the pavement tree tree-planting method of cement plate of the present invention guiding tree root growth downwards is characterized in that: use crane gear with the minor face of four trapezoidal cement plates be placed on apart from trunk 75cm, four long limits of trapezoidal cement plate down, minor face last, draw close each other, be trapped among tree around, bury apart from earth surfaces 30cm; On each trapezoidal cement plate, vertically place a rectangle cement plate then, the rectangle cement plate has that 30cm is embedded in the soil, 50cm elevates above the soil.

2. the pavement tree tree-planting method of cement plate guiding tree root according to claim 1 growth downwards, it is characterized in that: rectangle cement plate size is long 150cm, high 80cm, thick 10cm; Each rectangle cement plate has 2 lifting hole(eyelet)s, and the lifting hole(eyelet) size is the circular hole of diameter 5cm.

3. the pavement tree tree-planting method of cement plate guiding tree root according to claim 1 growth downwards is characterized in that: trapezoidal cement plate size is the long 150cm of minor face, long length of side 300cm, high 150cm, thick 10cm; Each trapezoidal cement plate has 2 lifting hole(eyelet)s, and the lifting hole(eyelet) size is the circular hole of diameter 5cm.
