Retaining wall for widening roads {REVETMENT FOR WIDENING STREET}

The present invention relates to a retaining wall for widening roads. More specifically, when the lanes are expanded to the side of the existing pavement constructed on the fill layer, the road width can be maximized and the road can be effectively expanded, and the construction can be performed relatively quickly. It can be easily taken to minimize the construction period and cost, and to maintain a solid installation state after construction to prevent lateral shifts in advance, and to reinforce the fill layer located in the existing pavement. It is related to the road widening retaining wall to minimize the problem of the road pavement deformation due to the uneven settlement of the fill layer.

In general, due to the rapid increase in vehicle supply, road conditions have deteriorated day by day, causing severe traffic jams everywhere.

Therefore, most road extension works such as the expansion of road roadway are mostly carried out in areas with frequent traffic such as highways and main roads.

In this case, it is common for such a road extension construction to expand and add fillet as much as it is equivalent to a distant lane.

This is preferred because of the relatively low construction cost and short air cost compared to new road construction, which requires a huge budget.However, there is a lack of land, land compensation and construction cost due to land price increase, air delay, increase in construction period, and safety. There were a number of problems such as accident risks.

Therefore, in recent years, in order to compensate for the existing problems, a method of expanding road roadway using retaining walls has been widely implemented.

However, when the road is widened by using the conventional retaining wall structure as described above, the following problems generally occur.

This is described in detail based on the order as follows.

First, when a certain period elapses, a transverse change occurs in the retaining wall by the imputation of the transverse pressure, causing a gap between the road and the retaining wall, and deterioration of the road quality due to the inflow of surface water.

Second, since the acting transverse earth pressure is supported by the frictional force of the retaining wall substrate, the retaining wall structure has to be enlarged because the width of the retaining wall substrate is inevitably wide in order to secure safety against stress conduction.

Therefore, in the expansion work of concrete pavement expressway, the existing surface is kept to the maximum, and the surface water is prevented between the road and the retaining wall to improve the lateral load acting on the retaining wall. There was an urgent need to reduce construction costs.

The present invention is to solve the above problems, the purpose of which is to maximize the width of the road when the lanes to the side of the existing pavement constructed on the fill layer to maximize the road width and at the same time construction Can be taken relatively quickly and easily, minimizing construction period and cost, and maintaining a solid installation state after construction, thus preventing lateral variation in advance, and filling in existing pavement It is to provide a retaining wall for widening the road to minimize the problem that the pavement of the road is deformed due to the uneven settlement of the fill layer by reinforcing the layer.

In the technical idea of the present invention to achieve the above object,

The vertical and horizontal portions are bent in a "┖" shape to be formed, and the vertical portion is formed with equally spaced strut insertion grooves in the longitudinal direction, and inside the vertical portion, a tie-net having a predetermined length is connected to the center. An exposed projection wall, in which a tooth projection is formed integrally with a tooth projection, and a horizontal portion has a plurality of fastening holes and drains;
