We conducted a comprehensive evaluation and overall assessment of the methods for dealing with obstacles in the construction method, considering aspects such as estimated construction period, estimated construction costs, safety, and reliability of construction.
You can download the materials comparing the methods for dealing with obstacles in the push construction method from CASE 1 to CASE 4, along with a comprehensive evaluation and overall judgment based on aspects such as estimated construction period, estimated construction costs, safety, and reliability of construction. 【Model Case】 Pipe Diameter: 1000mm Push Length: 100m Cover Depth: 10m Target Obstacle: H-200×1 location Soil Type: Ordinary 【Comparison of Obstacles in Push Construction Method】 ▶Normal Push The normal push method is used, but when encountering an obstacle, the tunneling machine is left in place, and the height of the pipeline is changed for re-pushing. ▶Normal Push The normal push method is used, but when encountering an obstacle, a shaft for obstacle removal is constructed, and the obstacle is manually removed before re-pushing. ▶Normal Push The normal push method is used, but when encountering an obstacle, the tunneling machine is left in place. ▶Milling Mole The route of the pipeline is changed for re-pushing, and the obstacle is directly cut using a milling mole tunneling machine.

basic information
The "Milling Mall Method" is a sub-surface obstacle response type of mud-based thrusting method equipped with four special functions: "exploration, improvement, cutting, and guidance." It consists of three devices: a tunneling machine, a special telescopic pipe, and a special injection pipe, allowing for the precise cutting and removal of underground obstacles. Using electromagnetic waves, it explores metal obstacles ahead while thrusting and can also improve the ground from within the tunneling machine before and after the detected obstacles.
