- the pavement, the containment die and the water drain channel are placed on said filling material.
- Korean Patent No. KR 10-2005-0082986A1 Another procedure for extending roads and highways is found in Korean Patent No. KR 10-2005-0082986A1, whose procedure includes as a first stage the placement of internal anchors on the slope. Once the anchors are placed, a layer of mortar is poured over the surface of the slope. The lower area of the slope is excavated and a base block is constructed or placed, which has a plurality of bolts that project upwards. On the base block, a segment of the retaining wall is placed or strained. Fill material is poured into the space between the slope and the retaining wall. Preferably said material is light mortar. A new segment of the wall is constructed and more filling material is poured. The operation is repeated until the extension reaches the level of the road. A reinforcement matrix is installed at the top and the asphalt is placed. If the retaining wall requires more support to support itself, anchors are inserted that project from the retaining wall to the slope.
- the procedure described above has the disadvantage that the retaining wall is formed by several prefabricated segments that are interconnected with each other, which can compromise the rigidity and continuity structural structure of said wall once it is finished.
- the retaining wall is formed by several prefabricated segments that are interconnected with each other, which can compromise the rigidity and continuity structural structure of said wall once it is finished.
