A powerful ally for bamboo cutting type pit door construction! Significantly shortens construction time and reduces costs!
The "Portal Out Form" is an external formwork for bamboo-split and protruding type tunnel entrances that allows for cost reduction and shortened construction periods. Since the formwork is modularized in the factory, assembly on-site is completed very quickly. It can be constructed without using separators, eliminating concerns about separator holes in the center. Additionally, it is registered with NETIS and has a track record of about 200 sites, including the Second Tomei Expressway. 【Features】 ■ Approximately one-third of the construction period compared to previous methods ■ Steel formwork and supports are integrated, so just assembly is sufficient ■ Easy installation and adjustment of formwork on-site ■ Assembly can be done using only a crane truck ■ Significantly reduces the number of days required before concrete pouring *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 - The formwork materials are combined with the support materials at the factory to create units that match the design dimensions. - The shape of the units is rectangular (width 2.3m, length 6.0 to 8.0m) considering truck transportation. - To improve the quality of the concrete in the crown section, the open area of the openings is kept as small as possible, with multiple concrete pouring windows. - Drain holes with a diameter of 10mm are provided to release breathing water and air from the concrete. - During unit assembly, temporary scaffolding for bolt fastening is equipped at the joints between the left and right units and the top unit. - Since wooden formwork is used minimally, it is possible to significantly reduce the generation of construction by-products. - By inserting embedded spacers, construction can be carried out without pipe supports and separators. *For more details, please refer to the PDF materials or feel free to contact us.
