Description

[Technical Field]

[0001] The present invention relates to a mountain trail construction device. [Background technology]

[0002] The logs used for conventional mountain trails are 15 to 25 centimeters in diameter and weigh 4 to 13 kilograms, and are secured by driving stake logs 50 to 70 centimeters into the ground. However, transporting the logs is hard work, and because the work is done on an inclined surface, transporting and driving the logs into the ground in places with poor footing can be dangerous. Furthermore, conventional mountain trails include those that extend horizontally and those that extend upward in a stepped pattern. Horizontal trails require widening work because soil washes out from the mountain side, narrowing the walking path. In this process, anchor means consisting of anchors and anchor bolts that support the logs are buried underground to prevent them from coming out of the ground. As shown in Patent Document 1, stepped trails are also prevented from coming out of the ground by burying anchor means that support the logs, some of which are buried underground and some of which are exposed above ground. However, when rainwater flows over the logs, it washes away the soil on the ground downstream of the logs, resulting in the logs and anchoring means becoming exposed above ground. Eventually, the logs and anchoring means are pulled out of the ground, damaging the hiking trail and causing it to become rough, as shown in Figure 11. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 60-104524 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made to solve the above problems, and aims to provide a lightweight, easy-to-use mountain trail construction device, and to provide a mountain trail construction device that can be configured to prevent damage to the mountain trail caused by rainwater flowing over retaining members that correspond to conventional logs, washing away the soil on the ground downstream of the retaining members. [Means for solving the problem]

[0005] In order to solve the above problems, the mountain trail construction device of the present invention is a mountain trail construction device equipped with a retaining member formed in a long, cylindrical shape from a corrosion-resistant material and filled with soil, a water leakage prevention means made of a sheet-like corrosion-resistant material that is attached to the retaining member, a retaining member fixing means made of a corrosion-resistant material that is attached to the retaining member, and anchor means made of a corrosion-resistant material that fixes the retaining member fixing means to the ground, wherein the retaining member is made of a horizontally long, rectangular plate material, and a first opening for putting soil into the retaining member is formed on the center line of the plate material in the short direction, and the retaining member forming member has a plurality of second openings for draining water formed on at least one side of the first opening, and is formed into a cylindrical shape. Furthermore, it is desirable that the retaining earth member of the mountain trail construction device of the present invention be configured by being clamped by a plurality of divided retaining earth member clamping members whose inner surfaces abut against the outer circumferential body of the retaining earth member. Furthermore, in the mountain trail construction device of the present invention, it is desirable that an earth retaining member fixing means be attached to the earth retaining member clamping material, and that anchor means be attached to the earth retaining member fixing means. [Effects of the Invention]

[0006] The construction device for a mountain path of the present invention is formed in a long cylindrical shape from a corrosion-resistant material and includes an earth retaining member that is used with soil filled inside, a drainage prevention means formed from a sheet-like corrosion-resistant material attached to the earth retaining member, an earth retaining member fixing means formed from a corrosion-resistant material attached to the earth retaining member, and an anchor means formed from a corrosion-resistant material for fixing the earth retaining member fixing means to the ground.

[0008] 1 to 10. The mountain trail construction device 1 includes a long, cylindrical soil-retaining member 2 made of a corrosion-resistant material and filled with soil; water-leakage prevention means 3 made of a sheet of corrosion-resistant material and selectively attached to the center or end of the soil-retaining member 2; soil-retaining member fixing means 4 made of stainless steel and made of a corrosion-resistant wire or chain attached to the soil-retaining member 2; and anchor means 5 made of a corrosion-resistant material and fixing the soil-retaining member fixing means 4 to the ground. The soil-retaining member 2 is made of a horizontally long, rectangular plate material, and is formed by winding a cylindrical soil-retaining member-forming member 9 around the plate. The first opening 6 for allowing soil to enter the soil-retaining member 2 is formed on a center line 7 along the shorter side of the plate material, and multiple second openings 8 for draining water are formed on at least one side of the first opening 6.

[0009] The retaining members 2 are made of stainless steel or synthetic resin, with their circumferential ends overlapping and fixed at the overlapping portions with a plurality of fasteners 10 consisting of screws or pins, and are clamped by two-piece retaining member clamping members 11 whose inner surfaces abut the outer circumferential body of the retaining members 2, with retaining member fixing means 4 attached to the retaining member clamping members 11 and anchoring means 5 attached to the retaining member fixing means 4. The retaining members 2 may be cylindrical or may have a cross-sectional shape with at least the top surface, which is the tread surface, flat to prevent shoes from slipping, or a polygonal cross-sectional shape such as a square to prevent slipping on the surface buried in the ground, and the shapes of the retaining member forming members 9 and the cover body 13 are also formed to correspond to the shape of the retaining members 2.

[0010] The retaining member 2 has four first openings 6 in a row at the top. These openings serve as introduction holes for pouring soil into the retaining member 2 and are oval-shaped with a straight center and semicircular ends for anti-slip purposes. These openings 6 are formed on the center line 7 of the retaining member-forming member 9 along the transverse direction, but do not necessarily have to be on the transverse center line 7. The retaining member 2 may be made of synthetic resin, but synthetic resin tends to turn into microplastics, which is undesirable for the environment. Therefore, a metal material such as stainless steel is preferred. Stainless steel retaining members 2 have an outer diameter of 120 to 250 mm, a thickness of 0.3 to 2 mm, and a length of 1000 mm. Both sides are open so that the retaining members 2 can be connected to each other. The end openings 12 are designed to allow detachable attachment of covers 13 or retaining members 2.

[0011] Before filling the retaining members 2 with soil, the retaining members 2 are connected to each other and the end openings 12 are closed with lids 13. In the embodiment, four first openings 6 are formed in a row on the top of the retaining members 2, each having a straight center and semicircular oval ends for anti-slip purposes, but they do not have to be oval, and they do not have to be in a row or four, as long as the determination is made taking into consideration strength, the introduction of rainwater, and anti-slip properties. When filling the retaining members 2 with additional soil, it can be filled through the first openings 6.

[0012] The second openings 8 are formed as round holes with a diameter of 1 to 5 mm, and the opening area is designed to allow only rainwater to drain without allowing soil to run off. Forming multiple second openings 8 for draining water on both sides of the first opening 6 has the effect of allowing construction without having to worry about the top and bottom, and forming multiple second openings 8 for draining water on one side of the first opening 6 has the effect of preventing a decrease in strength.

[0013] The retaining wall forming member 9 is designed with transportation in mind; a cylindrical retaining wall member 2 takes up space and is not suitable for transportation, but a flat or arc-shaped retaining wall forming member 9 can be stacked and transported, so multiple retaining wall forming members 9, each weighing 0.8 to 3.0 kilograms, can be efficiently transported at once.

[0014] As shown in Figure 7, the soil-retaining members 2 are fixed in place by fasteners 14 consisting of bolts and nuts in a state that prevents them from spreading outward. The soil-retaining members 2 are fixed by soil-retaining member clamping members 11 that are divided into two in the circumferential direction, and locking portions 15 are formed on both ends of the soil-retaining member clamping members 11 that protrude and into which the fasteners 14 are inserted or screwed. The soil-retaining members 2 are prevented from spreading outward by the soil-retaining member clamping members 11 and the fasteners 14, and are prevented from being crushed inward by the soil filled inside. However, if either the soil-retaining member clamping members 11 or the fasteners 14 can be used alone, it is sufficient to use either the soil-retaining member clamping members 11 or the fasteners 14.

[0015] The retaining member 2 may be formed from a pair of half-split members and folded into a cylindrical shape, which has the effect of making the retaining member 2 stronger.If there is no problem in not clamping the retaining member 2 with the retaining member clamping material 11 divided into two circumferentially, as shown in Figures 4 and 5, a simple structured retaining member fixing means 4 may be wrapped around the retaining member 2, and the retaining member 2 and the anchor means 5 may be connected by the retaining member fixing means 4.

[0016] The water leakage prevention means 3 is made of a deformable thin plate material, such as a stainless steel plate or a synthetic resin plate. A plurality of insertion holes 16 with a diameter of 2 to 8 mm are formed at the end or center of the water leakage prevention means 3 so that either the end or center can be selectively attached to the retaining member 2, but they may be formed at both ends. If the water leakage prevention means 3 is made of a synthetic resin material, it will turn into microplastics, which is undesirable for the environment, so it is preferable that it be made of a metal material such as stainless steel. Stainless steel water leakage prevention means 3 is formed with a width of 1000 mm, a length of 600 mm, and a thickness of 0.3 to 2.0 mm.

[0017] The water leakage prevention means 3 is preferably installed facing the soil retaining member 2, and may overlap adjacent water leakage prevention means 3 laterally, and the water leakage prevention means 3 may be installed with its upper surface exposed or covered with soil. By installing the water leakage prevention means 3, rainwater is prevented from seeping into the ground in front of the soil retaining member 2, weakening of the soil below the soil retaining member 2 can be prevented, damage to mountain trail construction equipment can be prevented, and the mountain trail can be prevented from becoming rough.

[0018] In the embodiment, the retaining member fixing means 4 is formed of a corrosion-resistant wire or chain, but it may also be formed of a plate or rod material.

[0019] The anchor means 5 is made up of an anchor or an anchor bolt, and has a notch to make it easier to attach the earth retaining member fixing means 4 and harder to remove.

[0020] The lid body 13 is fixed to the retaining member 2 so that it does not come off, and may be fixed with multiple screws, but as shown in Figure 8, it is also possible to form multiple cut-out portions 17 on the lid body 13, fold the cut-out portions 17 toward the inside of the lid body 13, and fit the folded end portion 18 into an opening formed in the retaining member 2 to prevent the lid body 13 from coming off, which has the effect of allowing the lid body 13 to be attached to the retaining member 2 with a single touch, improving workability.

[0021] Next, we will explain how to use the mountain trail construction device of the present invention.It can be used in both a connecting specification, in which the mountain trail construction device is used to construct a mountain trail that extends horizontally, and a stair specification, in which the mountain trail construction device is used to construct stairs.

[0022] When using the mountain trail construction device 1 of the present invention as a connecting model, the retaining member 2 is positioned along the mountain trail on the valley side of the trail, the upper side of the water leakage prevention means 3 is positioned on the tread of the mountain trail, and the length of the retaining member fixing means 4 is determined so that the anchor means 5 is located at the upper edge of the water leakage prevention means 3. The upper side of the water leakage prevention means 3 prevents rainwater from seeping into the mountain trail from the tread of the trail, preventing the interior of the trail from weakening. The lower side of the water leakage prevention means 3 is positioned to cover the lower slope of the mountain trail, so that rainwater that flows over the retaining member 2 or that is discharged from the second opening 8 flows over the upper surface of the lower side of the water leakage prevention means 3, thereby preventing damage to the mountain trail construction device that would be caused by washing away soil on the ground downstream of the mountain trail. The anchor means 5 is provided at the upper edge of the water leakage prevention means 3, but it may be positioned on the inside to prevent rainwater from entering the inside of the stairs and prevent the anchor means 5 from slipping out.

[0023] When using the mountain trail construction device 1 of the present invention for stairs, the soil retaining member 2 is positioned at the stair nosing, the upper side of the water leakage prevention means 3 is positioned on the stair tread, and the length of the soil retaining member fixing means 4 is determined so that the anchor means 5 is positioned at the upper edge of the water leakage prevention means 3. The upper side of the water leakage prevention means 3 prevents rainwater from seeping into the interior of the stairs from the stair tread, preventing the interior of the stairs from weakening. The lower side of the water leakage prevention means 3 is arranged to cover the riser and tread on the lower step of the stairs, so that rainwater flowing over the soil retaining member 2 and rainwater discharged from the second opening 8 flows over the upper surface of the lower side of the water leakage prevention means 3, thereby preventing damage to the mountain trail construction device caused by the washing away of soil on the ground downstream of the stairs. The anchor means 5 is provided at the upper edge of the water leakage prevention means 3, but it may be positioned on the inside to prevent rainwater from entering the inside of the stairs and prevent the anchor means 5 from slipping out.
