Milling Mall Method Construction Case: Sanjiyachishima Main Line Diversion Pipe Construction Project
Cutting at three locations in Matsuhang! Responding with forward exploration using electromagnetic waves and excavation management with a data logger.
This document introduces the construction achievements of the construction work for the Sangenya Chishima main line diversion pipe in Osaka City. Due to the presence of obstacles in the form of wooden piles, forward exploration using electromagnetic waves and excavation management using data loggers were conducted. Since the obstacles were wooden piles, no increase in excavation torque or thrust was observed, and the presence or absence of obstacle cutting was confirmed by the discharge of wood chips. 【Construction Case】 ■ Project Name: Sangenya Chishima Main Line Diversion Pipe Construction (Part 1) ■ Client: Osaka City Construction Bureau ■ Contractor: Kitabume Corporation ■ Pipe Diameter: 800 ■ Pushing Length: 127.61m ■ Soil Type: Sand and Silt ■ N Value/Gravel Ratio/Maximum Gravel Diameter: N=7 G=0% φmax=0mm ■ Construction Period: July 2, 2013 – August 10, 2013 (1 month) ■ Type of Obstacle: Wooden Piles φ150×3 pieces *For more details, please refer to the PDF document or feel free to contact us.
