DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a method for constructing a method, and more particularly, to a method and a method for constructing a method for constructing a method for protecting a slope, which is economical and has high durability.

[0002]

2. Description of the Related Art Conventionally, on a slope which is susceptible to surface erosion,
Concrete block framing is often employed as slope protection. This concrete block framing works when it is necessary to prevent gully erosion due to erosion or weathering due to rainwater, or when soil is unsuitable for vegetation and greening is required due to surrounding environmental conditions. It is effective on cut slopes with spring water, embankment slopes that are steeper than the standard slope, and when the surface may collapse even if vegetation is performed.

FIG. 7 is a schematic sectional view showing the structure of a conventional general concrete block framing method. Cut slope 50
As shown in FIG. 8, an elongated concrete block 52 as shown in FIG. Each concrete block 52 has a slope 5
The lattice shape is maintained by using the meshing shape at the intersection point 53.

[0004] An anchor pin 54 is cast near an intersection 53 of the concrete blocks 52 stacked along the slope 50. The anchor pin 54 prevents the assembled concrete block 52 from shifting. The anchor pin 54 is made of a reinforcing bar having a length of about 0.5 to 1.0 m, and its head is fixed to a part of the concrete block 52 or fixed with a filling mortar to deform the concrete block 52. It can be stopped.

Further, a filling material 56 is filled so as to cover the exposed ground 55 partitioned by the concrete blocks 52. For the filling material 56, locally generated soil is used as a customer soil material. In addition, chestnut, flat block, porous concrete, etc. may be applied to the filling material depending on the site conditions.

[0006]

However, since the concrete block used for the concrete block framing is a precast concrete product, the material unit price is high. In addition, one concrete block is also heavy, and it is necessary to use a lifting machine such as a crane when arranging it on the slope. For this reason, workability is significantly reduced in an area where a crane cannot be used, such as on a slope, or the like. Further, there is a problem that in a cold region or the like, the framing work is lifted by the influence of frost and the block is deformed. That is, it has been confirmed that when the anchor pin placed in the freezing area rises with the frost heave of the ground, the law frame fixed to the anchor pin floats integrally with the anchor pin. At this time, since the concrete block has high rigidity, it floats up during frost heaving or subsidence due to thawing, and cannot follow the subsidence, etc., and the blocks may compete with each other or torsion may damage the concrete block. .

Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, to use a readily available and inexpensive recycled material, and to have a flexible and durable method. It is to provide a construction method.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a law frame comprising a plurality of waste tires which are sequentially laid and arranged on a slope and which are connected to each other. It is characterized in that the slope is covered between the waste tires adjacent to the frame and the filling material filled in the tire.

In this method, the waste tires are laid one after another on the slope from the bottom of the slope, and the waste tires are connected to each other to construct a legal framework. It is characterized in that it is filled with a filling material, integrated into a layer, and constructed so as to cover the slope.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a method for constructing a method according to the present invention. FIG. 1 is an overall sectional view showing an embodiment in which a sill 10 according to the present invention is constructed on a slope 1. At the bottom end of the slope 1, a method casting concrete 2 made of precast concrete is installed. This method concrete 2
Is constructed by digging a local board so that the front surface has a predetermined depth. In this embodiment, a drainage mat 4 is laid on the sloped ground surface 3 as enlarged in FIG. The drainage mat 4 is laid for the purpose of securing a channel space for flowing down spring water from the ground surface. As the drainage mat 4, a mat in which resin fibers are three-dimensionally formed so as to obtain a porous space having a predetermined thickness (for example, about 1 cm) is used. This drainage mat 4 has such a rigidity that the porous space can be held against a plane load,
The thickness is secured even when waste tires described later are laid. Since an air layer is interposed between the ground surface 3 and the waste tire described later by the drain mat 4, an effect of preventing frost heaving of the framing work can be expected in winter.

Further, on the drain mat 4 laid on the ground surface 3, waste tires 13 are laid so as to be stacked along the slope. Here, the waste tire 13 is used as a vehicle tire such as a passenger car, and is intended to use the original form (product recycling) among the tires which are unsuitable for riding due to wear of the tread and discarded. Tires that have been used. As described above, the lowermost row of the waste tires 13 is supported by the method concrete 2 as a method of digging. At this time, each waste tire 13 is fixedly supported on the ground surface 3 by a tire fixing pin 19 having a predetermined length. The tire fixing pin 19 is fixed in the ground so that the drain mat 4 also penetrates the sidewall of the tire from the inside of the tire. The tire fixing pin 19 can be used by cutting a reinforcing bar having a predetermined diameter into a length that can secure a fixing length. Further, as shown in FIG. 3A, the waste tires 13 are connected by connecting bolts and nuts 18. As a result, the waste tires are integrated to form a legal frame. Further, a filling material 14 is filled in the waste tire frame and between adjacent tires. In this embodiment, locally generated soil is used, but it is preferable to select and use a vegetation bag, a sandbag, a chestnut stone or the like as appropriate according to the situation of the slope.

Waste tires 1 stacked along the slope 1
No. 3 forms a stable legal frame only by connecting tires when the gradient is gentle like an embankment slope. Therefore, it is sufficient to determine whether to use the tire fixing pin 19 according to the slope of the slope. In addition, the head of the tire fixing pin 19 is in the soil at a sufficient depth (about 30 cm) from the surface of the protective layer, and therefore is not easily affected by frost.

Although there are various standards for tire dimensions,
Waste tire 13 having substantially the same diameter and tread width
It is more workable to lay them all together. However, general passenger car tires having slightly different sizes can be used without any problem. Further, it is preferable to use waste tires 13 having greatly different sizes, such as tires for trucks and mini-vehicles, in order to adjust the dimensions at the end of the slope and to ensure stability at the lower part.

FIG. 2 is an enlarged partial sectional view showing a stacked state of the waste tires 13. As shown in the figure, a soil covering layer 15 is formed above the waste tire 13. The soil cover layer 15 is a layer formed by spreading the soil generated in the field to a uniform layer thickness of 5 to 10 cm and rolling, and plays a role as a fire protection layer for preventing a fire of the waste tire 13. In order to stabilize the soil covering layer 15, the surface of the soil covering layer 15 is
Covered with.

FIG. 3 exemplifies means for connecting the waste tires 13 to each other. In FIG. 3A, the connection by the bolt and nut 18 is performed using a through-hole (not shown) provided in a portion where the treads of the tire come into contact with each other. If necessary, a patch made by cutting a waste tire may be directed to the reinforcing portion in order to maintain the strength of the through hole. FIG. 3B is a diagram showing a modification in which the metal connecting plate 28 is addressed to the sidewall of the tire and is bolted to connect the tires. According to this example, after arranging the waste tires 13, the connection plate 28 can be attached by making a hole in the sidewall of the tire to be connected, so that workability is improved.

Next, a method of constructing the framing frame 10 will be described with reference to FIGS. First, as shown in FIG. 4, a drainage mat 4 is laid on a slope 1 shaped to a predetermined slope, so that a predetermined depth of penetration is ensured at the front of a settlement concrete 2 as a forehead work. To construct. It is preferable that a drainage work (not shown) is performed on the method concrete 2 so that the spring water flowing down the drainage mat 4 is drained to a drainage layer. Thereafter, the waste tire 13 is laid along the row of the method concrete 2 serving as the lower end guide. The waste tires 13 are fixed to the ground with tire fixing pins 19 as necessary, and in parallel with this, the tires are sequentially connected to each other by the connection method shown in FIG. In addition, each waste tire 1
The in-situ generated soil as the filling material 14 is filled into the space between the three and inside the tire surrounded by the sidewall. As a result, a legal frame integrally formed with the waste tire 13 as a whole is formed on the slope (see FIG. 5). Since the middle filling material 14 is filled in a large number of spaces defined by the waste tires 13, it is difficult for the middle filling material 14 to be washed away by rainfall or the like. In addition, since the tires are connected to each other and the entire legal frame is integrated to have an appropriate weight, stability of the slope is improved.

Further, as shown in FIG. 6, a soil covering layer 1 as a fire protection layer is provided to prevent a fire in the waste tire 13 portion.
5 is formed. The soil covering layer 15 may be set to such a thickness that the waste tire 13 is not exposed to the ground surface. Specifically, it is preferable to scatter the soil generated on site to a layer thickness of about 5 to 10 cm and compact it. Further, a wire mesh 16 is placed on the soil covering layer 15.
Cover with. As shown in FIG. 2, the wire net 16 is fixed on the surface of the soil covering layer by an anchor pin 17 formed by processing a steel rod. At this time, the anchor pin 17 can be fixed in the ground by penetrating the sidewall of the waste tire 13 by sharpening the tip.

Also, instead of the cast concrete 2 made of precast concrete, cast-in-place concrete and installation of a serpentine cage can be used to carry out proper cast work. If the slope is to be exposed for a long period of time, greening is performed on the covering layer by spraying with a turf or seeds to protect the covering layer 15 from erosion and the wire mesh 16 from corrosion. Then, a wire mesh may be further covered.

It goes without saying that the above framing method 10 can be applied to embankment and cut slopes set to various slopes in consideration of the degree of fixing by fixing means such as tire fixing pins. In addition, since the construction can be carried out without using heavy equipment and the like, the construction work can be quickly applied as an emergency restoration work for the existing slope collapse.

[0020]

As described above, by laying waste tires while connecting them along the slopes, a durable legal framework can be constructed at low cost and safely. This has the effect. Also, from the viewpoint of resource recycling, desirable effects can be expected as part of product recycling of waste tires.
