Addressed obstacles in six locations! We were able to achieve significant results in the construction project ordered by Kishiwada City.
In January 2012, we would like to introduce the achievements of the obstacle removal work that was successfully completed after cutting six steel sheet piles of Type III at a construction site ordered by Kishiwada City, Osaka Prefecture. After a thrust length of 432 meters with a diameter of 1000mm, we encountered the first obstacle approximately 100 meters after starting, followed by six consecutive encounters with obstacles over a distance of about 30 meters, with the remaining 222 meters being pushed through normally. The tunneling machine detected obstacles six times, cut through them six times, and reached the target with high precision using an electromagnetic wave guidance surveying device. 【Construction Case】 ■ Project Name: Kishiwada City Public Sewerage Section 1 Pipe Laying Work ■ Client: Kishiwada City, Osaka Prefecture ■ Contractor: Joto Construction Co., Ltd. ■ Pipe Diameter: 1000mm ■ Thrust Length: 432.34m ■ Soil Type: Sandy gravel ■ N Value/Gravel Ratio/Maximum Gravel Diameter: N=33 G=51% φmax=200mm ■ Construction Period: 2011.12.20 to 2012.3.15 (3 months) ■ Type of Obstacles: Six locations of steel sheet piles Type III *For more details, please refer to the PDF document or feel free to contact us.
