Abstract

PURPOSE: To provide at low cost a planting tree-tightening method for self- standingly and firmly fixing the root ball of a planting tree with piles so as to make the respective piles hammered into the ground act assuredly on the root ball without injuring the trunk of the tree. CONSTITUTION: This method for self-standingly fixing a tree is such one that the root ball 2 of a planting tree is placed at a hole 1 formed by digging the ground, plural piles 4 are hammered around the root ball 2 and a clamping equipment 5 continuously bridged on the upper ends of these piles 4 is temporarily tightened; subsequently, pressing pieces 8 set up around the trunk 3 of the tree and the respective upper ends of the piles are mutually clamped by relevant pieces 9 followed by removing the clamping equipment 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-supporting fixing method for planting which prevents a danger of falling down easily by wind pressure or the like during planting of a tree having a root pot formed therein for a while.

[0002]

2. Description of the Related Art As a prior art relating to a method for self-supporting and fixing trees for planting, FIG.
As shown in FIG. 6 which is a side view, a hole (10) having a desired size is excavated and formed in the surface of the ground to form a root pot (2) of a tree.
0), the pile (40) is driven into the root pot (20) so as to press a part of the upper surface and side surfaces thereof, and then the protective cloth (60) wound around the tree trunk (30). The fastener (50) composed of the wire (50a) and the winch (50b) is passed over the thimble (40a) formed on the upper surface of the opposing piles (40) (40) via the like, and then the winch (5)
By driving the wire 0b), the wire (50a) is tightened to strongly integrate the root mortar (20) and the pile (40), and the tree is self-supported and fixed in the root mortar (20) and remains in the hole (10). There is a method of completing the construction by backfilling the excavated soil in the gap, and furthermore, as shown in the attached plan view in FIG. 7, four piles (40) driven into the outer periphery of the root pot (20) There is also known a method of obtaining a desired pressing and holding force on the root mortar (20) by being tightened by a tightening tool (50) suspended via a thimble (40a) provided at the upper end thereof.

[0003]

In the above-mentioned prior art, in the method shown in FIGS. 5 and 6, the tightening tool (50) in which the wires (50a) and the winches (50b) are integrated with the opposing piles. Although the wire is tightened more tightly (50
a) the tree trunk (30) is pressed through the protective cloth (60), but in the method of FIG. 7, all four piles (40) are connected to the wire (50a) and winch. (5
0b) is integrally fixed with a large-sized tightening tool (50) at once, and in any case, one or more expensive tightening tools are permanently buried. What was economical, in the present invention, the expensive tightening tool in which the wire and the winch are integrated is made of an inexpensive material that is used for temporarily tightening the pile and is composed of the pressing piece and the mild steel wire. The present invention provides a method for self-supporting a tree at an extremely low cost, which is to remove the tree for re-use after the tree has been self-fixed without pressing the trunk tightly.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a tree for planting is strongly and self-supported and fixed, and a tree root is set in a hole excavated and formed in advance on the ground surface, and a plurality of piles are placed around the root. The pile was driven so that the upper end of the pile was flush with the upper surface of the root mortar, and the wire and the winch continuously extended over the upper end of each pile were tightened with a fastener to integrate the pile into the root mortar. Under the condition, the holding piece provided to surround the tree trunk and the upper end of the pile are tightened and connected by a flexible tightening piece, and then the tree fasteners for tightening the piles are removed to stand the tree independently. It is a method of fixing and finally backfilling earth and sand such as excavated soil in the voids in the holes to complete the planting of trees.

[0005]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, FIG. 1 and FIG. 2 show that each of the four piles (4) driven around the root basin (2) of the tree temporarily applies an arbitrary pressing force to the root basin (2) and sustains it. FIG. 3 is a plan view and a side view showing an embodiment in which the holding member (8) and the pile (4) are fastened to the tightening member (9) while maintaining the embodiment of FIG. FIG. 4 is a plan view showing a state in which the tree is strongly tightened by removing the tightening tool (5) which has maintained the state of FIG.

[0006] Next, the planting method will be described. As shown in Figs. 1 and 2, a hole (1) having a desired size is previously formed by excavation on the ground surface, and the hole (1) is formed. The root pot (2) formed on the tree is placed in the plant, and four L-shaped piles (4) are driven around the root pot (2) with an appropriate driving tool to The head is flush with the upper surface of the root pot (2) or reaches a position where the upper surface is recessed.

When the root bowl (2) swings or rotates due to natural wind pressure or the like only by driving the piles (4) as described above, each pile (4) is also moved independently and the pressure holding force of the piles itself decreases. In order to do this, it is necessary for all the piles (4) to act on one another in the root bowl (2).

As shown, a front locking piece (4b) and a rear locking piece (4a) are formed at the upper end of the pile (4). First, the wire (5a) and the winch (5b) are integrally formed. After the wire (5a) of the tightened fastener (5) is continuously extended over all the rear locking pieces (4a), the winch (5)
b) is driven to temporarily tighten each pile (4) until a desired pressing force is obtained.

Under the above-mentioned temporary tightening condition, the main tightening work is started, and as shown in FIG. 3, all the piles (4) indicated by the one-dot chain line are properly installed while maintaining the mutual tightening condition. The pressing piece (8) (for example, mild steel wire,
A string or a donut-shaped board may be used) and the front locking piece (4b) formed at the upper end of the pile is tightened and connected by a flexible tightening piece (9) such as a mild steel wire. The holding piece (8) must be positioned so as to be finally separated from around the trunk of the tree.

FIG. 4 shows a fastener (5) which becomes unnecessary when the tree is self-supported and fixed by such a final tightening operation.
Is removed for reuse, and the gap naturally formed in the hole (1) is backfilled with earth and sand such as residual soil at the time of excavating the hole, so that the desired tree for planting can be fixed independently. Complete.

L-shaped piles are used in the above-mentioned method for self-supporting trees, and log piles can be used as another example, although not shown, and two locking pieces at different positions are provided. The top of the log pile is the one that has one locking piece on each side of the L-shape, or the one where the fastener is attached to either the upper end surface or the upper rear side of the log pile. It may be of a form fixed so as to surround the corners of
A log pile having a two-step groove formed on the upper side surface can be used.

[0012]

As described above, according to the present invention, all the piles driven into the outer periphery of the root mortar are temporarily pressed and maintained on the outer periphery of the root mortar by the winding and tightening of the fastening device in which the wire and the winch are integrated. Then, at the time of the next tightening operation, the pile and the holding part are tightened and connected by an inexpensive tightening part such as a mild steel wire for each pile to achieve self-standing fixation of the tree, and the tightening tool is finally finished. Is extremely economical, including the fact that it is removed and reused, and since the holding piece is located away from around the trunk of the tree, there is no need for a protective cloth, of course. This method is most suitable as a method for firmly fixing rooted planting trees at an early stage without damaging the tree trunk, and its practical value is remarkable.
