Description

Polygonal block assembly and tree protector including the same}

The present invention relates to a multi-perforated block body, and more particularly, to include at least one multi-perforated block and at least one block fixing pin, characterized in that the multi-perforated block is supported in the ground or underground, the multi-perforated block it's about the body.

Trees growing in the city center include street trees, park trees, and landscape trees. These urban trees enhance the aesthetics of the city, provide greenery, and perform various functions such as temperature control and resting places for humans and animals. are doing

These urban trees are planted around roads where vehicles are driven, on sidewalks where pedestrians pass, or in parks close to walking trails with a lot of floating population. There are management problems such as sluggish growth due to obstacles on the road structure (sidewalks, trails), hardening of the soil and insufficient supply of moisture and air (oxygen) due to impermeable pavement materials and footsteps of pedestrians.

In particular, the lack of moisture causes damage to underground facilities in surrounding buildings and lift-up by roots such as sidewalk blocks and asphalt as the water-soluble roots continuously grow in search of moisture, which causes damage to pedestrians and structures such as loss of structures. Things are happening.

In addition, the trees in the city park are being hardened by foot pressure by pedestrians and the soil is being lost, such as exposing the roots.

Accordingly, in order to solve the above problems, devices or methods capable of supplying moisture and nutrients while protecting trees have been developed.

In relation to the prior art for the preservation of these urban trees, in Korea Patent Publication No. 10-1437121 (2014.08.27), it is a water supply and water supply and ventilation pipe device for street trees, which is located on the upper side and is opened so that water or nutrients are supplied. Including an inlet, a hollow communicating with the inlet in the vertical direction so that water or nutrients supplied from the inlet are supplied to a street tree, and a body portion positioned on the side of the hollow and having a plurality of supply holes communicating with the hollow Therefore, there is a technology related to a device for supplying water or nutrients to a street tree, but this has a limitation in the burial depth of the device as the inlet must be located close to the ground for water or nutritional supply, so it is a fine root located deep underground. There is a limit that cannot supply sufficient water or nutrients.

In addition, Korea Patent Publication No. 10-1087300 (2011.11.21) describes a technology related to a variable street tree protection plate using an eccentric circle, which is provided in a frame body in which a penetrating part is formed therein and the penetrating part, and is provided with concentric circles and Including a plurality of cover parts that can change direction in an eccentric circle, no matter where the street tree is in any position in the tree guard plate, a guard plate that can be installed quickly and accurately without cutting the street tree cover or tree is provided. As the roadside tree guard plate is located close to the ground surface, there is a limit to the protection of the roadside tree, and furthermore, there is a limit in solving the problem of moisture or nutritional deficiency of the roadside tree in the dry season such as winter because it does not have a function of supplying moisture or nutrients.

Therefore, while solving the problems presented in the prior art, it is easy to manufacture and can be deformed in various forms, and the development of a tree protector device that can be easily fixed and supported on the ground or underground to prevent the pushing phenomenon and shape deformation is difficult. It is urgently required.

) and pentagram (

) may be in any one shape selected from the group consisting of, through this, when combined with the polygonal perforated block according to the present invention, the polygonal perforated block having a polygonal cross section and the straight, cross-shaped, X-shaped, Y-shaped, Hexagonal (

) and pentagram (

) by combining any one shape selected from the group consisting of the block fixing pin, the multi-perforated block body can be manufactured and transformed into more various shapes by a combination thereof.

In FIG. 10, a plan view (a) and a perspective view (b) of a structure in which two polygonal perforated blocks having a regular hexagonal cross section at both ends of a connecting block having a straight cross section are coupled to each other by two block fixing pins by way of example In this case, the thickness of the fastening groove in the block fixing pin is provided such that two of the three fastening grooves are equal to the thickness of the support surface of the polygonal perforated block or at least 3 mm greater than the thickness of the support surface, and the remaining 1 The two fastening grooves may be provided so as to be the same as the thickness of the fastening part at the end of the connecting block, or at least not larger than the thickness of the fastening part by 3 mm or more.

In addition, as shown in FIG. 10, at least one opening is formed on the side surface of the connection block like the support surface of the multi-perforated block, so that moisture and/or air can move in the ground or underground, As a standard, the material including the soil filled inside and outside can move horizontally through the opening, so that nutrients such as oxygen movement, water exchange, and microorganisms can smoothly move between the pupils of neighboring multi-perforated blocks or neighboring soils. can be exchanged.

In addition, the present invention provides a tree protector including the multi-perforated block body described above, which will be described below with reference to FIGS. 11 and 12 .

11 and 12 are diagrams showing examples of various forms of a tree protector including a multi-perforated block body according to an embodiment of the present invention. Referring to FIGS. 11 and 12, a tree protector according to the present invention can be located on the ground surface as well as underground, especially directly above the fine roots of trees, and arrange the shape of multi-perforated blocks in a line in consideration of the growth environment of trees, planting type, drainage condition, soil compaction, and the position of fine roots of trees. It can be formed and installed in a combined linear form, in a planar form in which tree roots are connected in a circular or variable form, and in a multi-layered continuous non-continuous vertical connection.

In addition, the tree guard may be installed in a mixture with the boundary stone 301 on a newly planted tree, and may be installed in various forms according to the tree growth state in the boundary stone 301 of an existing street tree.

As described above, as the tree protector according to the present invention includes a multi-perforated block body, it is manufactured and installed in a suitable shape and depth around the tree, and can be stably buried in the earth pressure of the adjacent soil, as well as pedestrians or facilities. It is possible to prevent soil loss due to soil pressure or tread pressure and rainwater.

In addition, since the tree protector can be buried just above the fine root, that is, to the depth of the ground, it is possible to supply continuous moisture and nutrients even to the fine root of the tree, and to suppress abnormal growth of the exponential root. , through this, it is possible to suppress the lifting phenomenon by the roots of the sidewalk blocks around trees.
