DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a step for a mountain trail, and more particularly to a step for a mountain trail having a function of preventing scouring of a sidewalk surface due to a flowing water such as rainwater on the mountain trail.

[0002]

2. Description of the Related Art Since a mountain climbing road is compacted by the traffic of climbers, it has a terrain one step lower than the surrounding area. Therefore, the mountain trail becomes a waterway when rainwater flows down,
In particular, on a mountain road with a steep slope, the water flows like a waterfall, and the surface of the sidewalk is gradually scoured by this flowing water flow, and is cut into a U-shaped cross section. As a result, the rock surface is exposed and the sidewalk surface becomes severe with unevenness or muddy soil, making it difficult to walk.

Therefore, conventionally, steps have been installed on mountain trails,
There is a device that makes it easier for climbers to walk, but as a means, a structure is used in which a plurality of piles are driven into the ground, and a receiving plate is fixed to the part of the piles that protrudes from the ground surface, and the soil is retained. There were many steps.

[0004]

However, the conventional steps as described above have a main purpose of constructing a sidewalk surface which is easy for climbers to walk, and prevent scouring of the sidewalk surface caused by rainwater flow. No consideration has been given to doing so. Therefore,
In case of heavy rainfall, etc., the overflow water of the receiving plate scours the soil on the valley side of the steps, and the sidewalk surface is often deeper and U-shaped, and the receiving plate has no opening. As a result, the rainwater spilling into the lower part of the receiving plate flows like a waterfall at a stretch, and the lower part of the receiving plate is easily washed.

[0005] As a result, the ground around the pile is loosened, and the earth and sand tends to flow out. In some cases, the step itself collapses after a long period of time, and the pile and the receiving plate are made of wooden material in consideration of the surrounding scenery. In many cases, the deterioration is quick and the durability is short. And the decayed wood is left as it is,
On the contrary, there were drawbacks that the landscape could be spoiled.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and the present invention provides a step with water permeability and water flow velocity damping functions to reduce the flow rate of flowing water. The purpose is to prevent scouring on the sidewalk surface and to provide a landscape-friendly one. The gist of this is that a rectangular horizontal top plate and the opposite sides of this top plate A substantially U-shaped concrete block comprising a side wall portion installed toward a mountain side of a mountain trail hanging down from a side and a side wall portion higher than the mountain side wall portion installed toward a valley side of the mountain road, A plurality of openings are respectively formed in the top plate portion and the valley side wall portion, and natural stones are buried in upper surfaces of the climbing steps and the top plate portion, and the valley side wall portion is also embedded. On the outer surface, natural rock or a pattern imitating natural rock is applied. It is in the step for climbing road, characterized in that was.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the embodiments shown in the drawings. In the drawings, A is a precast concrete climbing step (hereinafter referred to as step).
A rectangular horizontal top plate 1 that is long in the left-right direction, a front side wall portion 2 hanging down from both front and rear long sides of the top plate portion 1 facing each other, and a height higher than the front side wall portion 2 It is mainly composed of the lower rear side wall 3 and is generally
It has a character shape.

The front side wall 2 is formed on an inclined mountain road R
And the height (H) is higher (H> h) than the height (h) of the rear side wall portion 3 installed toward the mountain side of the mountain road R facing the mountain. ) Is formed so that the top plate 1 can be installed horizontally on an inclined mountain road R. Reference numeral 4 denotes a rectangular opening formed in the top plate 1 and extending in the left-right direction. In the illustrated embodiment, two openings are formed apart from each other.

Reference numeral 5 denotes a circular opening formed in the front side wall 2, which is 1 (H) of the height of the side wall 2 in the illustrated embodiment.
At a position slightly higher than / 2 in the horizontal direction (longitudinal direction)
Are formed apart from each other. A cut surface 6 is formed at both corners of the lower end of the front side wall portion 2 and has a structure that can be easily installed on the mountain trail R washed in a U-shape. 7
Reference numeral 8 denotes a natural stone provided on the upper surface of the top plate portion 1 and embedded in a lower portion thereof. Reference numeral 8 denotes a natural rock or a pattern imitating a natural rock provided on an outer surface of the front side wall portion 2. As a result, it is possible to prevent slippage during walking and to provide a step having excellent durability and scenic properties.

Next, a description will be given of a method of using the step A having the above configuration. In the case where the step A is installed on a relatively steep mountain trail, as shown in FIG. A plurality of steps A are laid at intervals. At this time, the front side high side wall portion 2 is arranged toward the valley side, and the rear side low side wall portion 3 is arranged toward the mountain side, and the side wall portions 2 and 3 are arranged such that the top plate 1 is in a horizontal state. Embed the lower end of the underground and fix it.

Thereafter, the opening 4 formed in the top plate 1 is formed.
Gravel, crushed stones, etc. are put into the steps A from the top and filled, and at the same time, between the steps A, A, the gravel, crushed stones, etc. are almost flush with the upper surface of the lower top plate 1. Lay S2. As a result, the opening 4 formed in the top plate 1 is moved upward.
Further, the openings 5 formed in the front side wall 2 are opened in a state of being exposed to the valleys, respectively.

Therefore, during rainfall, rainwater collected on the mountain trail R which is one step lower than the surroundings penetrates into the inside of the gravel or crushed stone S2 laid between the steps A, A, and the side wall 3 on the rear side of the steps A. It flows in the direction S1 such as gravel and crushed stone in the steps A through the lower end side. If the amount of rainfall is large, gravel, crushed stone, etc.
Flows into the step A from the opening 4 formed in the top plate 1 of the step A, penetrates into the gravel or crushed stone S1 filled in the step A, and flows from the mountain side to the valley side. Flow down.

In the meantime, the falling water collides with the above-mentioned gravel and crushed stones S1 and S2 and flows down while bypassing the gaps of the gravel and crushed stones, so that the flow velocity thereof is attenuated. Most of the flowing water whose flow has become gentle is drained out of the step A from the opening 5 formed in the front side wall 2, and the above process is repeated in the step A of the lower step. The flow velocity of the flowing water is attenuated. After that, it will flow down the mountain trail R with a gentle flow. Therefore, the walking surface of the mountain trail R is not washed by the flowing water, and the washed mud does not stay.

FIG. 4 shows an installation example in which the slope of the mountain trail R is relatively gentle. In the case of this embodiment, the opening 5 formed in the front side wall 2 of the step A installed in the upper stage is laid so as to be substantially flush with the upper surface of the top plate 1 of the step A installed in the lower stage. It is covered with gravel and crushed stones S2. Therefore, the opening 5 of the step A installed on the upper stage is installed without being exposed to the outside.

The flowing water flowing into the upper step A and having its flow velocity attenuated by colliding with the gravel, crushed stones, etc. S1 therein, as in the above embodiment, Most of the water is drained out of the step A from the opening 5 formed in the side wall 2. Thereafter, by repeating the above-described operation, the flow velocity of the flowing water is gradually reduced, and the flowing water flows down the mountain trail R as a gentle flow. Therefore, the sidewalk surface of the mountain trail R is not washed by the flowing water,
Mud does not stay on the sidewalk.

[0016]

As described above, the climbing steps according to the present invention are installed facing the rectangular horizontal top plate and the mountain side of the climbing road hanging down from the opposite sides of the top plate. A substantially inverted U-shaped concrete block comprising a side wall portion and a side wall portion higher than the mountain side wall portion installed toward the valley side of the mountain trail, wherein the top plate portion and the valley side wall portion are provided. Since each of the openings has a plurality of openings, the flow rate of rainwater flowing down the climbing road is reduced at the steps of the climbing road, and scouring of the climbing road by the flowing water is reduced.
Therefore, the outflow of the earth and sand is reduced, and the inclined sidewalk surface is maintained in a step-like manner, so that it becomes easy to walk.
In addition, by adopting a structure in which natural rock or a pattern imitating natural rock is applied to the outer surface of the valley side wall portion, it is easy to walk without slipping, and it matches natural scenery in the surroundings. There are various effects that the destruction of the environment can be prevented.
