Course 130126 Strut-and-Tie Modeling (STM) for Concrete Structures
This Manual provides four design examples illustrating the application of the strut-and-tie method for a variety of structural configurations, including a simply-supported deep beam, a cantilever bent cap,
A Review of Vertical Shaft Technology and Application in Soft
In the manuscript, a systematic analysis of vertical shaft technologies, specifically focusing on their use in soft ground conditions, is conducted. The analysis is based on an extensive
Grid couplings
The grid, which, is the primary wear component of the coupling is designed for quick and easy replacement. Unlike other couplings, the hubs and other components are not disturbed.
Vertical Shaft Sinking Machine (VSM)
The Vertical Shaft Sinking Machine (VSM) from Herrenknecht enables the reliable and efficient construction of vertical shafts – even in complex ground conditions with high groundwater levels.
CSP for Vertical Applications: Understanding Design
Understand how the pressure applied to the shaft depends on the soil type, water-table height and other loads that may be applied to the shaft; and how these
Optimization of reinforced ring base depth for vertical shaft sinking
Design recommendations for vertical shaft sinking include a 16 m reinforced ring base depth, which effectively balances shaft stability while minimizing both lateral and vertical deformations.
Horizontal vs. Vertical: Learn the Direction Difference NOW!
From building walls (vertical) to laying roads (horizontal), knowing what direction is vertical and horizontal is essential. Why is understanding the difference important?
CSP for Vertical Applications: Understanding Design
A prevalent use for these products is vertical applications, which includes caissons for utility poles in electric transmission lines, bridge and building piers, wind
Tunnel Shafts: Types, Construction, and Advantages
What are tunnel shafts? Tunnel shafts are vertical passages that connect the ground surface to the tunnel roof. Shafts have many advantages and are used in constructing tunnels. When the position
Numerical study on a supercritical vortex drop shaft with a spiral
The present research provides new experimental data related to the flow field establishing across the vertical shaft. The study describes a CFD modelling, based on 3D Volume-Of-Fluid
A Numerical Study of Reinforcement Structure in Shaft
Using the Vertical Shaft Sinking Machine (VSM) for shaft construction is an emerging modern technology, which is also currently one of the most advanced techniques in the field of shaft
Study on Construction Approaches and Mechanics Characteristics of Shaft
The vertical shaft of the Huayingshan tunnel is constructed by the Top-down shaft method and the excavation technology of the Drill and blast excavation method.
Underground Mine Surface Access Sketches
ACCESS FROM SURFACE Access can be gained by vertical shafts, declines (also called drifts, slopes or ramps) or horizontal adits. The chosen method depends on topography, reserve shape, reserve
Towers of Suspension and Cable Stayed Bridges
Towers of bridges are vertical concrete or steel structures extended above bridge decks. Functions and conceptual design of bridge towers are discussed.
