The present invention relates to a geogrid installation apparatus of a fill portion, and more particularly, to a geogrid installation apparatus of a fill portion improved structure for fastening the geogrid deployed in the fill body to the natural stone forming the retaining wall of the front surface of the fill body.

In general, civil engineering or construction sites should consider reinforcement of incised slopes formed by cutting rock sections or grounds, or reinforcement of fill slopes that occur between different altitudes in the process of laying soil.

The cut section is a reinforcement structure for the inclined inclined surface formed by an arbitrary incision of a rock section or the ground, and the fill section is a reinforcement structure for a fill slope generated between areas having different altitudes during the filling process.

The retaining wall, which is a structure for reinforcing and protecting the inclined surface of the cut portion and the fill portion, may be constructed in various ways, and the construction method may be variously applied according to the characteristics of the inclined slope and the fill slope.

Typically, the retaining walls of the cut and fill sections can be constructed as structures using concrete pouring or structures using natural stone.

However, the retaining wall using concrete pouring lacks flexibility and variability corresponding to the shape of the slope and rock to be installed. And a support base is needed to solve the flexibility and variability, but a considerable space is required to secure the support base. In addition, securing such space requires a lot of backfilling work, and thus, the construction period is extended and construction cost is high. In the case of partial breakage of the retaining wall in the future, repair is difficult, and the landscape aspect considering the aesthetics is difficult to be satisfied.

In addition, the retaining wall using natural stone can satisfy the landscape aspect, and the flexibility and variability of the shape of the slope and the rock to be installed can be secured, but when the large natural stone is piled up with the fill, the natural stone is difficult to maintain in an upright state and is stacked in multiple layers. If you are not a highly skilled installer, natural stone can easily fall.

Among these, when the retaining wall is constructed with large natural stone in the fill, the natural stone may be supported by a geogrid that is deployed as a reinforcement in the fill.

The natural stone of the fill portion supported by the geogrid is arranged in an irregular shape, and the geogrid deployed in the fill body has an end portion formed in a direction orthogonal to the unfolding direction. Therefore, the spacing between the back of the natural stone and the end of the geogrid is difficult to remain constant.

As described above, an expensive fastening device such as a turn buckle may be used to fasten the distance between the natural stone and the geogrid end having different distances for each location, but this increases the construction cost and lowers the economic effect.

Therefore, it is necessary to present a fastening device that is securely fastened and inexpensive while naturally responding to the separation distance between the natural stone and the geogrid end arranged in an irregular shape.

The present invention for solving the above-mentioned problems is to provide a geogrid installation apparatus of the fill portion that can be firmly fastened to the natural stone and geogrid end that is arranged in an irregular shape at a low cost and flexibly corresponding to the separation distance.

Geogrid installation device of the fill portion according to the present invention, one end is inserted and fixed to the rear of the natural stone disposed on the front of the fill body three anchors formed with a male screw on the other end; A support bar coupled to an end of the geogrid that is horizontally developed in the fill body; Fastening rings including a ring engaged with the support bar and having a nut penetrating the ring and disposed one-to-one corresponding to the set anchors; Connection nuts having a female thread through which one end of the three anchors is coupled to the male screw, and has a length corresponding to a separation distance for each position between the natural stone and the geogrid; And computer bolts fastened between the other end of the connection nut and the fastening ring.

In addition, the geogrid installation apparatus of the fill portion according to the present invention, one end is fixed to the rear of the natural stone disposed on the front of the fill body and three anchors formed with a male screw on the other end; A support bar coupled to an end of the geogrid that is horizontally developed in the fill body; Fastening rings including a ring engaged with the support bar and having a nut penetrating the ring and disposed one-to-one corresponding to the set anchors; Connecting nuts having a penetrating female screw and fastened to the male screw of the three anchors at one end thereof; And computer bolts fastened between the other end of the connection nut and the coupling ring and having a length corresponding to a separation distance for each position between the natural stone and the geogrid.

According to the present invention, since the geogrid installation device of the fill part is constructed by combining low-cost parts, the natural stone and geogrid ends that are irregularly arranged at low cost can be flexibly responded to the separation distance while being firmly coupled.
