Description

  TECHNICAL FIELD The present invention relates to a tree support construction method, a support construction tool, and more particularly to a tree support construction method and a support construction tool to be constructed for street trees and the like.

  In recent years, the demand for urban greening has increased, and in response to this, artificially planted in various places in urban areas, such as parks, sidewalks, exhibition halls, parking lots, plazas, plazas, public open spaces, etc. Construction methods for constructing trees while supporting them are being implemented. And in such a support construction method, it is necessary to fix the root pot of a tree in an underground part, and various methods and tools are conventionally employ | adopted as such a support construction method and a support construction tool.

  For example, a method of fixing a root pot by hanging a string-like body such as a wire around the root pot, locking the string-like body to a driving member such as an anchor, and driving the driving member into the ground ( FIG. 12 etc. of Patent Document 1 below), or a method of placing a root pot on a mounting material instead of the anchor, and fixing the root pot by hanging a string-like body around the mounting material (Patent Document 2 below) 3), or a method of driving a pile-shaped member along the side surface of the root pot (Patent Documents 4 and 5 below).

  Such a method is, for example, a place in an urban area such as an exhibition hall, a plaza, a plaza, an open space, etc., and is mainly used for supporting and constructing a tree having a tree height of 3 m or more. The supporting tools used in the construction are also large-scale, and some construction cost is required.

  On the other hand, for example, a tree using a bipedal pillar made of traditional logs is still used for supporting construction of relatively small trees with a tree height of 3 m or less, such as trees planted in street trees. . However, when such a method using a bipedal support made of logs is adopted, the strength to support the tree is not necessarily sufficient.

  The present invention was made in order to solve such problems, and it does not become as large as a construction method or a support construction tool for supporting and constructing a tall tree having a tree height of 3 m or more. Compared with conventional construction methods and support construction tools, the cost is low, and especially when used as support construction for roadside trees, etc. It is another object of the present invention to provide a tree support construction method and a support construction tool whose cost is comparable to or cheaper than the method using such a bipedal support.

The present invention, in order to solve such problems, laying laying sheet 1 on the ground, on the laying sheet 1, the mounting base 2 for placing a root ball 17 trees 16, the A pedestal fixing member 3 comprising a pedestal holding body 4 which is pushed into the ground while holding the pedestal 2 from the upper side, and a driving body 5 which is hooked on the pedestal holding body 4 and driven deeper into the ground than the pedestal holding body 4. Then, the pedestal 2 is fixed , the root pot 17 is placed on the pedestal 2 , the root pot presser sheet 7 is placed on the upper surface of the root pot 17, and the root pot presser sheet 7 is Provided is a method for supporting and supporting a tree, characterized in that it is fixed and applied by means of a sheet holding means for pot holder. Such a support construction method is mainly applied to a so-called underground strut in which a root pot 17 is housed and supported in a planting hole 15 formed in advance on the ground. In that case, the laying sheet 1 is laid on the bottom wall surface 20 of the planting hole 15.

The present invention also provides a laying sheet 1 laid on the ground, a pedestal 2 mounted on the laying sheet 1 and for placing a root pot 17 of a tree 16, and holding the pedestal 2 from above. A pedestal holding body 4 that is driven into the ground while being held, a pedestal fixture 3 that is hooked on the pedestal holding body 4 and driven into the ground deeper than the pedestal holding body 4, and an upper surface of the root pot 17 A tree support holding tool, characterized in that it comprises a root pot presser sheet 7 placed on the root pot presser and a root pot presser sheet fixing means for fixing the root pot presser sheet 7. provide.

The sheet fixing device for roots Hachiosae, a root ball presser sheet 7, is used like a binding band 18 for fixing the root ball presser sheet 7 by tying with bridged on the base 2.

  In the present invention, as described above, a laying sheet is laid on the ground, a pedestal for placing a tree root pot is mounted on the laying sheet, and the root pot is placed on the pedestal. The root pot presser sheet is placed on the upper surface of the root pot, and the root pot presser sheet is fixed by the root pot presser sheet fixing means. The support strength is stable compared to the method, etc., and the method for supporting trees and the support tools can be provided at a cost comparable to or cheaper than the method using such a bipedal support. .

  As described above, the tree support method according to the present invention includes laying a sheet for laying on the ground, attaching a pedestal for placing a tree root pot on the laying sheet, and mounting the root on the pedestal. In this method, a pot is placed, a root pot presser sheet is placed on the upper surface of the root pot, and the root pot presser sheet is fixed by a root pot presser sheet fixing means.

  The tree support construction method of the present invention is mainly applied to a tree support construction method called an underground strut. Therefore, the laying sheet is laid on the bottom wall surface of the planting hole previously formed on the ground. In this way, when laying a laying sheet on the bottom wall surface of the planting hole, it is possible to attach a pedestal on the laying sheet at the construction site, but from the viewpoint of facilitating the construction and shortening the construction time, It is desirable that the pedestal is previously attached on the laying sheet. The mounting of the pedestal on the laying sheet is performed by, for example, bonding with an adhesive or the like, but can be mounted by other means.

  Further, the tree support construction tool of the present invention is a sheet for laying laid on the ground, a pedestal mounted on the sheet for laying and mounting a tree root pot, and an upper surface of the root pot. A root pot presser sheet to be placed and a root pot presser sheet fixing means for fixing the root pot presser sheet.

  The laying sheet is used by laying it on the ground, especially the bottom wall of the planting hole, and contributes to the stability of the tree by the weight of the soil backfilled around the laying sheet. Also, because of the sheet, root growth is not hindered and the roots are firmly attached over time, and the strength is maintained. The material of the laying sheet is not particularly limited, but from the viewpoint of preventing destruction of the natural environment, it is desirable to use a degradable material that can be embedded in the soil and decomposed. Examples of the decomposable material include natural fibers such as palm fiber, hemp, cotton, and jute, straw, paper, and the like. Among these, it is desirable to use palm fiber or hemp from the viewpoint of ease of handling and cost.

  Further, the pedestal improves the stationary stability of the initial root pot, and prevents the root pot from being inadvertently displaced due to rotation or the like on the pedestal, as will be described later. The material of the pedestal is not particularly limited, but it is desirable to use a wooden material. By using a wooden pedestal, it can be disassembled when a certain number of years have passed since it has been buried in the soil, like a laying sheet, and thus contributes to the prevention of destruction of the natural environment. Moreover, it is because the cost of a base can be made cheap by using a wooden thing.

  The shape of the pedestal is not particularly limited, but it is desirable that the pedestal be formed in a shape suitable for placing the root pot. For example, a wooden prism-shaped frame member arranged on four sides and formed into a substantially square frame shape is used. By using such a substantially square frame-shaped flat surface, a rounded root pot is generally placed on the pedestal while being locked to the frame-shaped pedestal. In this case, inadvertent displacement of the root pot on the pedestal is prevented.

Pedestal is fixed by further pedestal fixing means. Such pedestal fixing means is not particularly limited. For example, in the case where the pedestal is formed into a substantially square frame shape by arranging wooden frame members on the four sides as described above. A member that is driven into the ground so as to straddle the frame member of the pedestal can be used. More specifically, for example, two members, a pedestal holding body that is pushed into the ground while holding the pedestal from the upper side, and a driving body that is hooked on the pedestal holding body and is driven deeper than the pedestal holding body. A pedestal fixture such as can be used.

  As described above, the pedestal 2 is mounted on the laying sheet 1 by, for example, bonding with an adhesive, but by fixing the pedestal 2 by the above-described pedestal fixing means in addition to such mounting means, It is possible to suitably prevent the pedestal 2 from being carelessly detached from the laying sheet 1 and floating. It is also possible to attach the pedestal 2 to the laying sheet 1 only by a pedestal fixing means such as the pedestal fixing tool 3 without adopting an attaching means such as bonding with an adhesive as described above. In this case, the pedestal fixing means itself becomes a means for attaching the pedestal 2 onto the laying sheet 1.

The root pot holding sheet is for pressing and fixing the root pot from the upper surface side, but because it is a sheet, the whole root pot is pressed and the bite into the root pot is small. . Since root pots of small trees are particularly weak, it is effective to hold the root pot with a sheet-like member such as a root pot holding sheet. The material of the root pot holding sheet is not particularly limited, and synthetic fibers and natural fibers can be used. From the viewpoint of preventing the destruction of the natural environment, it is desirable to use natural fibers such as hemp, cotton, coconut fiber, jute, etc., in the same manner as the above laying sheet, but the root pot presser sheet is a root pot presser sheet. Since it is fixed by the fixing means, when an external force such as a tightening force by such a root pot presser sheet fixing means is generated, from the viewpoint of preventing the root pot presser sheet from being torn carelessly, the strength It is desirable to use a strong synthetic fiber. As the synthetic fiber, for example, polypropylene is used from the viewpoint of versatility and cost.

  Further, as the root pot holding sheet fixing means, for example, a binding band for fixing the root pot holding sheet by bridging the root pot holding sheet and the base is used. When such a binding band is bridged between the root pot presser sheet and the pedestal, for example, the root pot presser sheet may be provided with a hole through which the binding band can be inserted, and the binding band may be hooked on the pedestal. Attach a fastener that can be used to hook one end of the binding band to the hook, and insert the other end of the binding band into the hole of the root pot holder sheet, in addition to the binding band inserted into the hole. The binding band is bridged between the root pot presser sheet and the pedestal by returning the end side to the latching tool attached to the pedestal and hooking the latching tool to the other end of the binding band. It becomes.

  Such a binding band is composed of, for example, a head portion and a trunk portion, has a hole in the head portion, and moves in the reverse direction by inserting the distal end portion on the distal end side of the trunk portion into the hole in the head portion. Thus, a binding band having a so-called non-returning function can be used. Such a binding band is a binding band generally referred to as Insulok (registered trademark: manufactured by Hemaran Taiton). The material of the binding band is not particularly limited, and for example, a material made of a synthetic resin such as polyamide (aliphatic polyamide) or polypropylene can be used. By using a binding band having such a non-return function, inadvertent detachment of the binding band from the hook can be suitably prevented. Further, such a binding band has an advantage that the work for binding is simple, the work can be performed in a short time, and it is difficult to loosen and come off easily. However, it is also possible to use a general string-like body in place of such a binding band having a check function.

  As a latching tool for latching the binding band, for example, a latching body formed in a substantially S-shaped side surface so that the binding band as described above is latched, and the latching body are latched, It is possible to use a member composed of two members, a fixed body that can be driven and fixed to the pedestal.

  Hereinafter, more specific embodiments of the present invention will be described with reference to the drawings.

Both the driving body 5 and the pedestal holding body 4 are made of metal such as iron.

  As shown in FIG. 4, the root pot presser sheet 7 is formed in a substantially square planar shape, and is composed entirely of synthetic fibers made of polypropylene. A circular tree insertion hole 8 for inserting a tree is formed in the approximate center of the root pot holding sheet 7, and a single notch 9 communicates with the tree insertion hole 8 to form the root pot. The presser sheet 7 is formed to face one corner. Further, one of the four corners of the root pot holding sheet 7 is provided with one insertion hole 10 for inserting a binding band, which will be described later, so that the notch 9 faces. Two insertion holes 10 are bored in the corner portion formed at the corner so as to straddle the notches 9. The two insertion holes 10 and 10 are formed at positions asymmetric with respect to the cut 9.

  As shown in FIG. 5, the binding band 18 has a head 18a wider than the body 18b at the upper part of the elongated body 18b, and a tip 18c at the lower part of the body 18b formed in a sharp shape. It has been done. Although not shown in FIG. 5, the distal end portion 18c is inserted into the head portion 18a of the binding band 18 in a state where the body portion 18b is bent so that the lower distal end portion 18c is returned to the head portion 18a side. Such a hole is drilled. This hole has a so-called non-return function that allows the tip portion 18c to be inserted in the insertion direction, but preferably prevents the tip portion 18c from coming out in the direction opposite to the insertion direction. Is. The binding band 18 is entirely made of polyamide.

  As shown in FIG. 6, the latching tool 11 has a latching body 12 that is formed in a substantially S-shaped side surface so that the binding band 18 is latched, a latching body 12, and a base. 2 and a fixed body 13 which is fixed by being driven. As shown in FIG. 6, the fixed body 13 includes a substantially ring-shaped head portion 13 a and a body portion 13 b formed at a lower portion of the head portion 13 a, and a distal end portion 13 c of the body portion 13 b is sharp. It is formed into a shape. The hole portion 14 of the substantially ring-shaped head portion 13a is formed to have an inner diameter such that the side surface substantially S-shaped hooking body 12 can be inserted. Both the retaining body 12 and the fixed body 13 are made of a metal such as iron.

  As shown in FIG. 7, the laying sheet 1 and the pedestal 2 are integrated in advance by bonding the pedestal 2 onto the laying sheet 1 with an adhesive or the like. Further, as shown in FIG. 8, the latching tool 11 is fixed and attached in advance to the four corner portions of the base 2. More specifically, as shown in FIG. 9, the fixed body 13 of the latching tool 11 is driven into the base 2, and the latching body 12 is inserted into the hole 14 of the head 13 a of the fixed body 13. The latch 11 is attached to the base 2 by setting the latch 12 to the fixed body 13.

  In this case, as shown in FIG. 9, the fixed body 13 is attached by being driven into the pedestal 2 in a state where only the head portion 13 a is bare and most of the trunk portion 13 b is embedded in the pedestal 2. ing. In FIG. 9, for the sake of convenience, the side surface substantially S-shaped latching body 12 is illustrated in a standing state, but the latching body 12 is swingably latched with respect to the fixed body 13. Therefore, actually, the latching body 12 is attached to the fixed body 13 in a laid state.

  Next, a method for performing tree support construction using the tree support construction tool having the above-described configuration will be described.

  First, as shown in FIGS. 10 to 12, the laying sheet 1 in which the pedestal 2 is integrated is accommodated in a previously formed planting hole 15, and the laying sheet is placed on the bottom wall surface 20 of the planting hole 15. 1 is placed. In this case, when the outer diameter of the laying sheet 1 is formed larger than the inner diameter of the planting hole 15, as shown in FIGS. 15 is bent toward the side wall surface 21 side. As described above, the latch 11 is attached to the base 2 in advance.

  Next, as shown in FIGS. 13 to 15, the four pedestal fixtures 3 are attached to the prisms 2 a, 2 b, 2 c, and 2 d constituting the four sides of the pedestal 2, respectively. More specifically, as shown in FIG. 16, the upper holding part 4a of the pedestal holding body 4 is brought into contact with the upper surface of the pedestal 2, and one of the pair of falling parts 4b and 4b of the pedestal holding body 4 is contacted. The leading end portions 4c and 4c of both falling portions 4b and 4b are arranged so that the falling portion 4b is along the side surface of the base 2 and the other falling portion 4b is slightly separated from the side surface of the base 2 as shown in FIGS. As shown in FIG. 17, it is driven into the bottom wall surface 20 of the planting hole 15. The tip portions 4c and 4c of these pedestal holders are driven into the bottom wall surface 20 through the laying sheet 1 as shown in FIG.

  Then, the pedestal holding body 4 is inserted in advance into the hole 6 of the head 5a of the driving body 5 from the other falling part 4b side driven into the bottom wall surface 20 so as to be separated from the side surface of the base 2, As shown in FIGS. 16 and 17, the trunk portion 5 b of the driving body 5 is inserted into the base 2 in a state where the upper pressing portion 4 a of the base holding body 4 is inserted into the hole 6 of the head portion 5 a of the driving body 5. The body portion 5 b and the tip portion 5 c of the driving body 5 are driven into the bottom wall surface 20 of the planting hole 15. The tip portions 5c and the like of these driving bodies 5 are driven into the bottom wall surface 20 through the laying sheet 1 in the same manner as the tip portion 4c of the pedestal holding body.

  In this case, the upper surface of the pedestal 2 is brought into contact with the upper pressing portion 4a of the pedestal holding body 4, and the tip portions 4c and 4c of the pedestal holding body 4 are driven into the bottom wall surface 20 of the planting hole 15, and further With the upper presser 4a of the pedestal holding body 4 inserted into the hole 6 of the head 5a of the driving body 5, the tip 5c of the driving body 5 is driven into the bottom wall surface 20 of the planting hole 15. Therefore, by the driving of these three tip portions 4c, 4c, 5c, the pressing force by the upper pressing portion 4a of the pedestal holding body 4 effectively acts on the pedestal 2, and as a result, the pedestal 2 is It will be securely fixed on the laying sheet 1 without causing any positional displacement.

  Next, as shown in FIGS. 18 to 20, a root pot 17 of the tree 16 is placed on the pedestal 2. In this case, since the pedestal 2 is securely and firmly fixed by the pedestal fixing tool 3 including the pedestal holding body 4 and the driving body 5 as described above, when performing the operation of placing the root pot 17, The pedestal 2 is not inadvertently peeled off from the laying sheet 1 and is not lifted up or displaced.

  Next, as shown in FIGS. 21 and 22, the root pot presser sheet 7 is placed on the upper surface of the root pot 17. More specifically, the root pot presser sheet is formed such that the tree 16 is inserted into the tree insertion hole 8 that starts from the portion of the cut 9 formed in the root pot presser sheet 7 and communicates with the cut 9. 7 is placed on the upper surface of the root pot 17. In this case, since the notch 9 is formed so as to go from the tree insertion hole 8 to one corner portion of the four corner portions, the tree 16 is inserted into the tree insertion hole 8 of the root pot presser sheet 7. When inserting, the notch 9 is suitably cleaved, whereby the operation of inserting the tree 16 into the tree insertion hole 8 can be easily performed.

  Next, as shown in FIGS. 23 and 24, four binding bands 18 are bridged between the root pot holding sheet 7 and the latch 11. More specifically, as shown in the figure, one end of the binding band 18 is hooked to the hook 12 of the hook 11 and the other end of the binding band 18 is used for holding the root pot in this state. The binding band 18 is sequentially inserted into the insertion hole 10, the other end side of the binding band 18 is returned to the hook 11, and the other end of the binding band 18 is also hooked on the hook 12 of the hook 11. Stop.

  In this case, of the four binding bands 18, the three binding bands 18 are inserted into one insertion hole 10 in the triangular corner portion as shown in FIG. As shown in FIG. 25, the binding band 18 of the book is inserted into the two insertion holes 10 at the corners where the notches 9 are formed, and returned to the latching tool 11 side. Stop. In this manner, the four binding bands 18 are respectively inserted into the insertion holes 10 formed in the four corner portions of the root pot holding sheet 7 and are attached to the four corner portions of the base 2. Both ends of the binding band 18 are hooked on the tool 11.

  In this case, both ends of the binding band 18 are hooked to one end of the hook 12 of the hook 11, and the fixed body 13 hooked to the other end of the hook 12 is driven into the base 2. Therefore, even if tension is generated in the binding band 18 by a tilting force or the like acting on the tree 16, the binding band 18 is not inadvertently detached, and the hanging body 12 and the root pot presser sheet 7 are separated. A tension is suitably generated in the bound binding band 18 and the root pot 17 is securely fixed. Further, since the binding band 18 has a non-returning function as described above, the binding band 18 that is stretched between the retaining body 12 and the root pot holding sheet 7 does not loosen carelessly. .

  Then, as shown in FIG. 26, the soil 19 is accommodated in the planting hole 15, whereby the root pot 17 is embedded in the soil 19, and the support work of the tree is completed.

  As described above, the tree support construction tool of the present embodiment is composed of the laying sheet 1 made of palm fiber, the root pot presser sheet 7 made of polypropylene fiber, the wooden pedestal 2, and the polyamide. The constructed binding band 18 is used as a main constituent member for holding the root pot, and the iron base fixing tool 3 for fixing the base 2 and the binding band 18 are hooked as other auxiliary constituent members. The support construction tool is made up of only these using iron hooks 11, so that the support construction tool has a simple structure as a whole, and support construction of a relatively small tree with a tree height of 3 m or less like a roadside tree. It has come to be able to provide a support construction tool suitable for.

  Moreover, since the binding band 18 is bridged between the pedestal 2 on the laying sheet 1 and the root pot holding sheet 7 and the pedestal 2 is fixed by the pedestal fixture 3, it is used for supporting a tree such as a roadside tree. The support strength of the root pot becomes better than the conventional method using a bipedal support made of logs.

  Further, since the laying sheet 1 is covered with soil, the weight of the soil acts on the laying sheet 1 and the pedestal 2 attached to the laying sheet 1 and the tie band 18 are bridged to the pedestal 2. Since it also acts on the whole root pot presser sheet 7 integrated, the root pot 17 can be favorably supported in the underground part, so that the tree in the ground part as in the method using the above bipedal support. Compared with the method of supporting the root pot, the support strength of the root pot is further improved.

  Further, since the pedestal 2 is formed by connecting four wooden prisms 2a, 2b, 2c, and 2d, and the whole is formed in a frame shape of a substantially square plane, such a frame shape pedestal having a substantially square shape. When the root pot 17 is placed on 2, the bottom of the root pot 17 is caught, whereby the inadvertent movement of the root pot 17 is more preferably prevented.

  Furthermore, since the main structural members for holding the root pot, such as the laying sheet 1 and the pedestal 2, are made of natural fiber or wooden material, the support construction tool is buried in the soil for a certain number of years. As time passes, these components will be disassembled. Further, the root pot presser sheet 7 made of synthetic fibers and the synthetic resin binding band 18 are not materials that can be decomposed in the soil, but can deteriorate to some extent over a certain number of years. Furthermore, since the metal base fixing tool 3 and the latching tool 11 that are difficult to disassemble are small component parts, they are less affected by the natural environment even if they remain in the ground. . In any case, in the present embodiment, since a large metal component is not used, it contributes to prevention of destruction of the natural environment.

  Further, as a fixing means for fixing the root pot presser sheet 7, it is not necessary to use a mechanical tool such as a winch, which is conventionally used for supporting and supporting trees of a high tree, and it is extremely Since simple constituent members can be used, the construction can be further facilitated and the cost can be further reduced.

  Furthermore, since all the constituent members are inexpensive, the cost of the entire support construction tool is also low.

  In addition, in the said embodiment, as mentioned above, the case where the root pot 17 was accommodated in the planting hole 15 previously formed in the ground and the root pot 17 was supported by the underground part was demonstrated. However, the present invention is not limited to application to such underground struts.

  Further, the shapes and materials of the laying sheet 1, the pedestal 2, the pedestal fixing tool 3, the root pot presser sheet 7, the binding band 18, and the like are not limited to the above embodiment, and are within the scope of the present invention. It can be changed arbitrarily.
