Description

Reinforced soil method using waste tire

The present invention relates to a reinforcement earth process using waste tires having geometrical characteristics such as shape, size, and structure of waste tires, and physical and chemical material properties, and in particular, a plurality of waste tires having a plurality of holes perforated on a trade surface. It is to be connected to the fixed slope to install the integrated one on the inclined slope, but the rear part of the laminated tire is connected to the auxiliary tire to install and to be reinforced with a string or anchor.

In general, reinforcement soil method is a method of reinforcing earth structure by inserting reinforcement into the soil body. As the soil and reinforcement are integrated, a soil retaining wall or reinforcing soil is used to improve the bearing capacity and slope stability of the soil. The structure consists of three basic elements: faceplate, reinforcement and backfill.

Since the front plate and the reinforcement may cause stress bias due to the floating settlement of the foundation part and the poor compaction of the fill part, the front plate and the reinforcing material are provided with deformability to the wall itself or the connection between the wall and the reinforcement material. It is used a lot because of the friction and drainage, but it is not used because it is difficult for compaction and damages reinforcement during compaction.

As described above, the general reinforcement soil method firstly, when the fill height is less than 7 ~ 8m, the construction cost is more expensive than the other method. In addition, the uniformity of compaction is necessary to prevent stress bias on the connection part, and the backfilling material must have friction and drainage ability. Therefore, non-adhesive soil such as sand and gravel is expensive, and fourthly, when backfilling with poor drainage There was a problem that the horizontal drainage system needed.

In order to solve this problem, there are domestic patent applications No. 90-16574 and Korean patent applications No. 92-22373, which are previously filed. The upper and lower layers drill the sides of the tire and bind them using bolts and nuts. This is because the number of perforated holes is about 6 to 12, which makes the drilling work cumbersome. There is a problem that it is difficult to apply to high fill, and the latter form a wall by using a U-shaped bolt binding device after drilling holes on the trade surface and side wall of the tire. It is designed to be used as a dike or retaining wall for civil engineering work. Since tires must be joined with U-shaped bolts or ordinary bolts and nuts, the material cost and fastening cost are high, and when the retaining wall is used, there is a problem that the retaining wall may fall forward because there is no anchor device or reinforcement, and there is no horizontal drainage system. Therefore, in case of rainfall, the underground water level is increased and the stability of the fill layer is weakened. Also, when the cross-sectional shape of the tire is stacked in the form of C, it is difficult to fill and compact the earth and sand to the top of the tire, so the stability of the retaining wall is difficult. There was a problem falling.

In order to solve the above problems, the present invention facilitates the drilling work by drilling three to four holes in the waste tire, and facilitates the construction by continuously binding the perforated tires to the fixed line including the bead wire. In addition, the ability to withstand stress increases, and the ability to cope with earthquakes and landslides is increased, and one of the bead wires and side portions of the tire is cut to facilitate soil filling and compacting during layering, further increasing the stability of the retaining wall. The purpose is to make the hole large so that the free space can be used as a drainage passage after binding the fixed line.

In order to achieve the above object, the present invention is to cut a single bead wire and a portion of the side portion of the tire, and the front surface is integrally formed by stacking a plurality of waste tires with three holes perforated at the position of the tie on the trade surface. The plate wall is installed along the inclined surface, and four holes are drilled to face each other on the trade surface of the tire at the rear of a predetermined tire which is a component of the faceplate wall. The reinforcement tire plate formed by bringing it into close contact with the fixing line is laid long to be horizontal with the front plate wall, covered with a set soil, and then chopped, and then the other face plate wall and the reinforcement tire plate are chopped. The purpose is achieved by installing on the inclined surface in the same manner as

The reinforcement tire plate 5 is formed by being connected to the fixing line 4 so as to be in close contact with each other, including the bead wire, by the hole 3b drilled on the trade surface. 3) A plurality of front plate wall tires 6 formed by cutting three bead wires and one side of the bead line and a portion of the side portion are laminated, and the fixing line 4 is formed by holes 3 and 3a drilled in the trade surface. Passage forms the bounded front plate wall 7.

The front part of the reinforcement tire plate 5 formed in the planar shape is passed through the fixing line 4 through the hole 3 drilled in the rear side of the waste tire 6 which is a component of the front plate wall 7. The reinforcement soil wall 8 is comprised.

The front plate wall 7 of the reinforcement soil wall 8 is installed on the concrete foundation 9 formed at the bottom of the inclined slope, but the reinforcement tire plate 5 is horizontal to the rear of the front plate wall 7. It is a method of compacting by filling up a predetermined height with the earth and sand so that it is long.

At this time, the inside of the front plate wall 7 and the reinforcement tire plate 5 is filled with a filter material 9 such as sand and gravel to play a drainage function in the fill layer.

The reinforcement soil wall 8 may be stacked in such a manner that the front plate wall 7 is stacked in a predetermined interval and height according to the angle of the inclined surface formed, and filled in the soil.

The fixed string 4 is composed of synthetic fibers, synthetic rubber and wire rope or a composite material having a high tensile strength and high weather resistance, abrasion resistance, corrosion resistance and flexibility.

The installation method of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

In order to use the tire as a front plate wall of the earthen reinforcement soil method as shown in FIG. 3, the tire number of stages is illustrated as four plates and the number of tire layers at each stage in five layers. Determine the load and tire characteristics.

First, as a lower base 13 facility, the concrete in which the grooves 12 are grooved in the longitudinal direction is formed in the center portion, and the external drain pipe 10 is buried, and then the gravel 11 is filled in the water channel and the nonwoven fabric is covered on the upper portion.
