High seismic performance for architectural structures! Ground improvement methods directly beneath existing structures for liquefaction countermeasures.
The "Grand Flex Mall Method" is a technology that combines flexible boring techniques capable of controlling straight and curved paths underground with various ground improvement technologies. This method addresses various challenges in ground improvement directly beneath existing structures when work cannot be performed from above the existing structures or when the available surrounding land is limited. It can accommodate a wide range of target grounds and achieve construction objectives such as soil purification and cavity filling, not just liquefaction countermeasures. 【Features】 ■ Direction control ■ Drilling position confirmation ■ Double pipe structure ■ Impact penetration For more details, please refer to the catalog or feel free to contact us.
