Simultaneously completed with the stacking of blocks! Road widening construction method!
The Wide Wall Method is a road widening system that is completed simultaneously with the stacking of blocks. It involves using trapezoidal blocks on top of large blocks to achieve road widening. Similar to the conventional construction of large stacked blocks, road widening can be accomplished simply by "stacking blocks," allowing for a maximum road widening of approximately 2.0 meters with three layers of Wide Wall blocks. It is ideal for the installation of pull-off areas, bus stops, and sidewalks in mountainous regions where full two-lane conversion is difficult! <Received the 11th National Land Technology Development Award "Regional Contribution Technology Award">

basic information
〇 It can suppress the vertical height of the retaining wall. The top of the block expands in a trapezoidal shape, allowing for a reduction in the vertical height of the retaining wall. As a result, the retaining wall's supports can be smaller, contributing to improved cost-effectiveness and constructability. 〇 It is effective in reducing the required land and earthwork volume. Since the vertical height of the retaining wall is smaller compared to the required widening, it is possible to significantly reduce the volume of earthwork, contributing to shortened construction periods and reduced overall project costs. Additionally, the required land area is also smaller, minimizing the impact on the surrounding environment. 〇 It is ideal for 1.5-lane conversion in mountainous areas. The development of 1.5-lane roads involves creating passing areas on single-lane roads in narrow areas such as mountainous regions, partially converting them to two lanes. The wide wall construction method minimizes excavation impact, making it possible to achieve 1.5-lane conversion at a low cost.
