Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope protection body using logs such as thinned wood in consideration of environment and landscape.

[Prior art]

[0002] Methods for preventing the collapse of earth and sand include a method of constructing an earth retaining wall by casting concrete in place, a method of using a concrete block, and a masonry method. Conventionally, only structural strength, economy, or ease of construction has been emphasized, and the impact on the landscape, friendliness, and ecosystem has not been considered.

[0003] In addition, concrete blocks are often used for embankments of small and medium-sized rivers in terms of economy.
In agricultural waterways or small-scale waterways for water supply and drainage related to living, it is common to use fences made of concrete plates or U-shaped blocks.

In the conventional construction method, the position of the structure in the natural environment has been neglected, resulting in an artificial and inorganic landscape. By developing and disseminating construction methods for earth retaining walls and river revetments, and waterways that are more natural and friendly to humans and animals and plants, multi-natural structures that can inhabit a wide variety of insects and small fish are desired. ing.

[0005]

In addition, a large amount of cedar and cypress blanks are generated, but the blanks are low in value as building materials, and cultivation for other uses is being sought. The inventor has
We have researched and developed a wooden retaining structure that uses natural logs to make use of these materials for civil engineering.

[0006] It is an object of the present invention to provide a slope stabilizing protection body and a retaining wall body which are made of wood which can be protected and harmonized with the environment and which can be easily constructed.

[0007]

A panel unit is prepared by arranging and fixing a plurality of logs in a factory,
This panel unit is piled up at the site to form a fence, connected to a fixed pile and fixed, and this fence is connected to an anchor cast on the back to obtain a stabilized slope protection body as a structure It is. Slope stabilization to prevent landslides by stacking and installing panel units at intervals to form a fence-like body, placing wooden anchor piles in the gaps between panel units, and fixing the anchor piles to fixed piles You get the protection. When constructing the log material into the panel unit, stainless steel bolts are used to prevent corrosion.

[0008]

[Function] Since logs are unitized as panels in a factory, construction on site can be performed efficiently. All the panel units, fixed piles and anchor piles that make up the slope protector are made of wood, and the use of thinning materials is expanded, and the exposed surfaces are all made of wood. It doesn't give too much feeling. In places of high earth pressure, the anchors prevent the bar from tipping over.

[0009]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of an embodiment of the slope protection body of the present invention. FIG. 2 is a front view, and FIG. 3 is a sectional view of a panel unit.

Reference numeral 1 denotes a panel unit, which has a standard size of 30 × 300 (cm) in consideration of handling convenience. Three logs 15 each having a diameter of about 15 cm are cut into upper and lower surfaces to be overlapped as a flat surface, and holes 12 penetrating vertically are formed.
And a stainless steel bolt 13 and a nut 14 were used to form a log panel. The diameter of the log 11 constituting the panel is 10 to 20 cm.

The fixed pile 2 is also made of thinned wood and has a diameter of about 10 to 20 cm and a length of about 250 cm, and has a sharpened tip. The bolt 13 is, as shown in FIG.
It is connected through a log 11 constituting a panel, and is fixed by a nut 14 screwed to a bolt 13. The anchor 3 is driven into the ground to prevent collapse of the slope protection body due to pull-out resistance, and it is preferable to use a cast-in type branch anchor in terms of construction efficiency.

The construction procedure will be described. The branch anchors 3 are cast at intervals of about 3 meters with respect to the slope, and the mounting portions of the branch anchors 3 are exposed from the slope. The fixed pile 2 is vertically driven into the ground at an interval of 1.5 meters. Next, the panel units 1 are sequentially stacked to form a fence-like body, and are fixed to the fixing pile 2 with bolts. The anchoring portion of the anchor is fixed to a metal fitting provided on the panel unit 1 or the fixed pile 2, or is fixed on the front side by penetrating the panel unit 1 and the fixed pile 2. A tension is applied to the anchor by the turnbuckle 4 of the branch anchor 3 to fix the slope protection body. Panel unit 1
Fill the backfill between the slope and the slope to complete the slope protection body.

A second embodiment will be described with reference to FIGS. 4, 5 and 7. First, the fixed pile 2 is driven into the ground at an interval of 1.5 meters along the slope. The first-stage panel unit 1 manufactured in the factory is installed between the fixed pile 2 and the slope, and is fixed to the fixed pile 2 with bolts. First stage panel unit 1
A wooden anchor pile 3 is cast on the slope on the upper side. The anchor pile 3 is driven until the head of the anchor pile 3 protrudes from the fixed pile 2 by several centimeters, and the anchor pile 3 is fixed to the fixed pile 2 with bolts. A resistor is provided at the tip of the anchor pile 3 to increase the pull-out resistance.

The second-stage panel unit 1 is installed above the anchor pile 3 and fixed to the fixed pile 2 with bolts. Therefore, a gap equal to the diameter of the anchor pile 3 is formed between the panel units. This operation is repeated to fix the plurality of panel units 1 to the fixed stakes 2 to assemble the slope protection body having a required height.

[0015]

According to the slope protection body of the present invention, a wooden slope protection body having sufficient strength can be constructed efficiently and sufficiently using wood, which can achieve environmental protection and harmony. Is more natural.
