Mold for raceway operation at a road construction

摘要

The present invention relates to a formwork for the construction of the raceway during road construction, conventionally, because the bottom and sidewalls of the raceway are not manufactured at the same time, but are individually manufactured by wooden formwork, it takes a long construction period, is expensive to manufacture and reuses the formwork. This was difficult and there was a problem that the quality of the raceway deteriorated.;Therefore, the subject innovation is to install the outer plate 120 upright on both sides of the ground 300 of the excavated road and connect the upper fixing rod 110 to the upper side of the outer plate 120, and then have a constant interval inside the outer plate 120. The inner plate 130 is fixed to the upper fixing stand 110, and the bottom of the bottom plate by placing concrete between the outer plate 120 and the inner plate 130 in a state in which the lower fixing stand 140 is installed. After the 210 is formed and the bottom plate 150 is installed on the bottom surface of the inner plate 130, the concrete is poured again between the outer plate 120 and the inner plate 130 so that the side wall 220 is formed. By removing the formwork to complete the construction of the raceway, the construction period can be shortened, and even without high-quality manpower, the construction can be easily performed and the formwork can be reused to reduce the overall construction cost.
