Special Assembly Method "Reverse Driving Method"

A special assembly method for advancing concrete work from top to bottom.

Our company employs the "reverse excavation method," where we construct the first-floor slab in advance while simultaneously building the upper floors and excavating downwards to create the basement levels sequentially. Compared to traditional earth retention methods, this approach allows for excavation to be carried out with minimal loosening of the ground, enabling stable underground construction supported by the structure. Additionally, regarding the upper structure, work can be conducted in parallel with the underground structure from the early-constructed first-floor slab, which helps shorten the overall construction period. 【Customer Benefits】 - By using the permanent floor beams as temporary support, underground construction is safe, and there is minimal impact on the surrounding ground (ground deformation). - The ability to progress with both underground and above-ground construction simultaneously allows for a reduction in construction time. - The first-floor beams can be utilized as a working platform, making it possible to control the impact on the surrounding environment (noise, dust). *For more details, please download the PDF or contact us.
