Ecology & Ground Restraint Effect! New Long Steel Pipe Cutting Edge Reinforcement System
The "Me Method" is a small-diameter long steel pipe face reinforcement technique applied in weak ground conditions such as tunnel entrances and unconsolidated ground during mountain tunnel excavation. By enlarging the connection part, it enhances the strength of the threaded section, allowing the use of small-diameter thin-walled steel pipes (φ76.3×4.2mm), which improves economic efficiency and workability due to weight reduction. Additionally, "Me-fix" aims to improve the adhesion strength, which has been a weakness of previous steel pipe face reinforcements, ensuring reliable ground confinement. 【Features】 ■ Recycling of steel materials through separate collection ■ Thinning of steel pipes through enlarged connection parts (socket method) ■ Improved adhesion strength of long steel pipe face reinforcements *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Construction Method】 1. Set the bit adapter and rod on the leading pipe and begin drilling. 2. After driving the leading pipe into the ground, disconnect the rod at the shank and connect the next intermediate pipe and rod to continue drilling. 3. Continue drilling sequentially using the same procedure, and when the specified length of steel pipe has been installed, rotate the rod while retracting to detach the ring bit. The slime remaining in the steel pipe will be discharged using flushing water. 4. Retrieve the rod and bit adapter. 5. Completion of steel pipe installation. *For more details, please refer to the PDF document or feel free to contact us.
