Side scraper

As the shield machine advances, the cutter rotates with the cutter head, generating axial (along the tunnel's advance direction) shear forces and radial (tangential to the cutter head's rotation) cutting forces on the excavated soil.

Product Details

Keywords: Tuoda Engineering Equipment

The configuration of soft soil tools is crucial in the design of shield machines and pipe jacking machine tools. Whether the configuration is suitable for the geological conditions of the application project directly affects the service life, cutting effect, soil discharge, excavation speed, and construction efficiency of the shield machine. Soft soil tools are the main tools on the cutting excavation surface of the shield machine. Cutting tools are used to excavate non-rocky or soft soil geology, sand, gravel, and clay loose formations with particle sizes less than 400 mm. The Tuoda technical team designs the most reasonable tools for each customer based on customer needs and geological conditions.

Tuoda has established a scientific and reasonable manufacturing process for the production and processing of soft soil tools. The tool manufacturing process is the key to controlling tool quality.

Tuoda's production process uses: integral forging ~ integral heat treatment ~ silver brazing cemented carbide, resulting in products with higher reliability and good wear resistance.

Cutting tools are soft soil tools, arranged on both sides of the cutterhead opening slot. The cutting principle is that as the shield machine advances, the cutting tools rotate with the cutterhead to generate axial (along the tunnel's forward direction) shear force and radial (cutterhead rotating tangential direction) cutting force on the excavated soil. Under the rotation of the cutterhead, the blade and cutterhead insert into the stratum, continuously cutting away the soil in front of the excavation face. Cutting tools are generally suitable for loose formations such as sand, gravel, and clay with particle sizes less than 400 mm.
