Description

Slope reinforcing structure and slope constructing method

The present invention relates to a slope reinforcing structure and a method for constructing a greening slope using the same, and in particular, by adjusting the spacing of wire meshes placed on both sides in order to cast concrete, the slope reinforcement can be arbitrarily controlled by the thickness of cement. The present invention relates to a structure and a method for constructing a green slope using the same.

In general, when some slopes of the mountain slopes or hills are damaged by natural disasters such as heavy rain or flooding, the damaged slopes are shaved by a certain amount, and the soil is filled in the areas to form new slopes. When a new back is opened, the mountain slopes or hills are cut by a certain amount to flatten the opened surface, and then the rest is formed as a new slope.

In addition, if a bank or embankment is formed near a river or a lake in order to prevent flooding of rivers and use of water resources, slopes due to soil filling are formed as in the above case.

When the unstable slope of the fill area or cut area created by cutting or filling up the soil as a new terrain as described above is left uncovered, the soil is easily lost due to various natural causes such as heavy rain or flood. In addition, the surface of the inclined surface can be installed by installing a separate protection and reinforcement structure on the inclined surface because it is not only necessary to perform the repair work on the inclined surface frequently but also in severe cases, the inclined surface of the earth can collapse and cause great life and property damage. Risk factors such as collapse and rockfall from activities should be blocked in advance.

Therefore, various methods for stabilizing the inclined surface have been developed for the above reasons. Among them, the wire mesh is installed on both sides, and the gap retaining member is installed between the wire meshes. The method of curing by pouring was representatively used.

However, the above method has a problem in that the thickness of the concrete to be poured cannot be adjusted because the gap between the wire meshes is fixed because the width of the gap holding member is fixed.

The present invention has been made to solve the problems of the prior art, it is configured to adjust the width of the gap holding member disposed between the wire mesh to adjust the gap between the wire mesh, as a result It is an object of the present invention to provide a slope reinforcing structure that can control the thickness of concrete poured between the wire mesh and a greening slope construction method using the same.

Slope reinforcing structure according to the present invention for solving the above problems is an octagonal gap retaining member consisting of a rectangular wire mesh and eight circular hollow tubes disposed between the wire mesh to maintain the spacing between the wire mesh Consisting of, the vertical circular hollow pipe disposed vertically to the wire mesh is characterized in that the length is adjustable.

In addition, the green slopes construction method according to the present invention is a wire mesh installation step of arranging the wire mesh of the rectangular shape, the gap holding member installation step of installing and fixing the gap holding member between the adjacent wire mesh, and A shotcrete placing step of placing shotcretes between wire meshes adjacent to each other to maintain a predetermined interval by a spacing member; and a shotcrete fixing step of nailing or anchoring the shotcrete at a predetermined interval, and filling the soil inside the wire mesh; It is composed of fill phase to plant plants.

Slope reinforcement structure according to the present invention configured as described above and the greening slope construction method using the same because the length of the upper and lower circular heavy space of the gap maintaining member is adjusted, thereby adjusting the gap between the wire mesh installed on both sides of the gap maintaining member There is an advantage that can be adjusted to the thickness of the concrete poured between the wire mesh.

Hereinafter, with reference to the accompanying drawings an embodiment of a slope reinforcing structure according to the present invention will be described in detail.

1 is a perspective view showing a state in which a gap retaining member according to the present invention is installed on a wire mesh, FIG. 2 is a perspective view showing a gap maintaining member according to the present invention, and FIG. 3 is a greening using a slope reinforcing structure according to the present invention. A perspective view of the slope.

Slope reinforcing structure according to the present invention is composed of a wire mesh 10 is installed on both sides and the gap maintaining member 20 is disposed between the wire mesh 10 to maintain the spacing of the wire mesh 10.

The wire mesh 10 has a plurality of reinforcing bars arranged in a horizontal direction and a vertical direction at a predetermined interval, and configured in a grid shape having a predetermined area.

At this time, the size of the grid is formed small enough to prevent the cement and gravel, etc. contained in the concrete to be discharged to the outside through the grid. Therefore, even if the formwork is not padded on the outer surface of the wire mesh 10, the wire mesh 10 and the gap maintaining member 20 are cured in a state where the concrete is firmly attached in the concrete due to the viscosity of the cement itself.

The gap maintaining member 20 is composed of an octagonal shape in which eight circular hollow pipes are tail-tailed, and the upper and lower circular hollow pipes are disposed perpendicular to the wire mesh 10 among the eight circular hollow pipes. (22, 24) is formed to be adjustable in length.

In addition, the left and right circular hollow pipes 26 and 28 arranged horizontally on the wire mesh 10 among the eight circular hollow pipes are firmly connected to the wire mesh 10 using a coupling string 30 such as a wire. .

The upper and lower circular hollow pipes 22 and 24 formed to be adjustable in length have first hollow pipes 22-1 and 24-1 disposed on one side, and outer diameters of the first hollow pipes 22-1 and 24. It is formed of a second hollow pipe 22-2, 24-2 formed smaller than the inner diameter of -1) and slides while a predetermined portion is inserted into the first hollow pipe 22-1, 24-1.

The first hollow pipe 22-1, 24-1 has an end, more specifically, the second hollow pipe 22-2, at an inlet portion into which the second hollow pipe 22-2, 24-2 is inserted. The first engaging projections 22-1a and 24-1a protruding toward the outer circumferential surface of 24-2 are formed at predetermined heights, and the second hollow pipes 22-2 and 24-2 are formed at the ends of the first hollows. The second locking projections 22-2a and 24-2a are formed to protrude toward the inner circumferential surfaces of the pipes 22-1 and 24-1 to be engaged with the first locking projections 22-1a and 24-1a.

The first locking projections 22-1a and 24-1a and the second locking projections 22-2a and 24-2a will be described in more detail. The interval is the same as the outer diameter of the second hollow pipe (22-2, 24-2) and the length, the interval between the second engaging projection (22-2a, 24-2a) is the first hollow pipe (22) -1,24-1) is formed to have the same inner diameter and length.

Accordingly, while the second hollow pipes 22-2 and 24-2 are inserted into the first hollow pipes 22-1 and 24-1 and slide, the second hollow pipes 22-2 and 24-2 are slid. When attempting to break out of the first hollow pipes 22-1 and 24-1, the first locking projections 22-1a and 24-1a are caught by the second locking projections 22-2a and 24-2a. This prevents the second hollow pipes 22-2 and 24-2 from being completely separated from the first hollow pipes 22-1 and 24-1.

On the other hand, on one side of the outer circumferential surface of the first hollow pipe (22-1, 24-1), support nuts (22-1b, 24-1b) having a predetermined height is provided by welding or the like, the support nut (22-) The fastening bolt 40 having a predetermined length is inserted into 1b). At this time, the support nut (22-1b, 24-1b) to the portion of the first hollow pipe (22-1, 24-1) in which the support nuts (22-1b, 24-1b) are installed to communicate with the support nuts (22-1b, 24-1b) Through-holes 22-1c and 24-1c are formed to have a size equal to or slightly larger than the inner diameters of 22-1b and 24-1b, and the fastening bolt 40 is formed through the through-holes 22-1c and 24-1c. It is inserted into the first hollow pipe (22-1, 24-1) through.

Therefore, when the fastening bolt 40 is rotated and inserted into the first hollow pipes 22-1 and 24-1, the ends of the fastening bolts 40 are first hollow pipes 22-1 and 24-1. In contact with the outer circumferential surface of the second hollow pipe (22-2, 24-2) inserted into the, and then continues to insert the fastening bolt 40, the fastening bolt 40 is the second hollow pipe (22) By strongly pressing the outer circumferential surface of -2, 24-2, the positions of the second hollow pipes 22-2 and 24-2 inserted into the first hollow pipes 22-1 and 24-1 are fixed. Therefore, the relative position of the first hollow pipe (22-1, 24-1) and the second hollow pipe (22-2, 24-2) is fixed by the fastening bolt 40, the gap maintaining member ( 20) is prevented from changing the width. Through this process, the width of the space keeping member 20 is adjusted, and as a result, the spacing of the wire mesh 10 is adjusted and the thickness of the concrete that is poured between the wire mesh 10 is adjusted.

On the other hand, greening slope construction method according to the present invention is a wire mesh installation step of arranging the wire mesh 10 of the rectangular shape in a grid form, and the space maintaining member (provided in the above configuration between the adjacent wire mesh 10) ( 20) installing and fixing a gap holding member for installing and fixing the shotcrete (C) placing the shotcrete (C) between the wire mesh 10 adjacent to each other to maintain a predetermined interval by the gap holding member (20); It consists of a shotcrete fixing step of nailing the nail or anchor (N) at a predetermined interval on the shotcrete (C), and the filling step of filling the soil (S) in the inside of the wire mesh 10 and planting the plant.

The filling step is to install a vinyl between the wire mesh 10 and the soil sand (S) before filling the soil (S) to prevent the soil sand (S) flows out between the scale of the wire mesh (10). Of course, if the scale of the wire mesh 10 is made sufficiently small, it is possible to prevent shotcrete or earth and sand particles from leaking to the scale of the wire mesh 10. However, when using the wire mesh 10 having a large scale, a vinyl may be installed. Soil and shotcrete can be prevented from spilling and mixing with each other.

On the other hand, the recording slope construction method configured as described above is not always performed in that order, it will be obvious that the order may be changed in part depending on the situation of the work site.
