The "Micro Joint Pile Method" is a rock embedding method using special short-length jointed steel pipe sheet piles that eliminates the need for pre-drilling at the joint sections. By utilizing special short-length joints (micro joints) to shorten the pitch, the labor of pre-drilling is eliminated. By installing micro joint-type steel pipe sheet piles specifically designed for this method at approximately one-fourth the conventional short pitch, pre-drilling at the joint sections becomes unnecessary, allowing for simultaneous rock excavation and installation of steel pipe sheet piles in one process. 【Features】 ■ Construction technology review certification obtained ■ Direct installation of steel pipe sheet piles into rock layers is possible ■ Rental options for steel pipe sheet piles are available ■ Elimination of pre-drilling labor through pitch shortening with special short-length joints *For more details, please refer to the PDF materials or feel free to contact us.

The "PRD-ROSE Method" is a group of open-end down-the-hole hammer drilling technologies that allows for the selection of methods tailored to various construction conditions such as diverse terrain, soil types, and excavation diameters. With a crane-suspended construction style, it can flexibly accommodate the distance and elevation differences between heavy machinery scaffolding and the center of the pile, while also minimizing the installation area of the heavy machinery scaffolding. Thanks to a variety of drilling techniques, including large-diameter low-vibration and low-noise drilling with CD (Cluster Drill) type hammers for hard rock formations, rapid construction is achieved under diverse site conditions. 【SINGLE TYPE Features】 ■ Standard type for open excavation ■ Suitable for stable ground with stable borehole walls ■ Capable of large-diameter drilling up to 1,830mm *For more details, please refer to the PDF materials or feel free to contact us.
