Description
Slurry Mechanical Seal for BAUER Trench Cutter Systems
Structural Features: single end, multiple springs, with spring protector, balanced, independent direction of rotation. The component is cartridge seal with easy installation. The compensation components are supporting the sleeve. The springs are not touching the subjects so that there will be no jam caused by the high viscosity and crystallization active content. This makes sure the flexibility of the compensation ring and as a result, it lasts the lifetime of the whole component.
Industrial Standards: DIN24960, ISO3069, ANSI B73.1M
Scopes of Application: The construction of diaphragm walls is a standard specialist foundation engineering technique. It covers a wide range of different applications in almost all kinds of geotechnical conditions. It provides various solutions for load bearing (reinforced in situ concrete wall, barrettes) and sealing purposes (cut-off walls). A continuous wall is formed by a series of individual rectangular panels. During the excavation, the open trench is stabilized by a supporting fluid (e.g. thixotropic slurry). Depending on the wall type, the construction process differs after reaching the final excavation depth. As the trend shows an increase of excavation depth in the future, the cutter system provides an economical and technically approved solution.
