A review of ice and snow risk mitigation and control measures for ...
2022年1月1日 · Since the collars were primarily designed to remove wet snow, which is the most common source of bridge cable icing in the area, they might get jammed in hardly packed and frozen snow or slide over it.
To secure traffic safety and to reduce long bridge closures, it is important to develop novel measures against ice accretion. A literature review of existing de- and anti-icing techniques within the fields of bridges, wind turbines, airplanes and power lines has been carried out.
Numerous cable-supported bridges in cold climate regions are prone to seasonal ice or snow shedding, primarily from the bridge cables. Specific atmospheric conditions are required to...
A review of ice and snow risk mitigation and control measures for ...
Numerous ice prevention and removal methods for bridge cables have been tested in the last two decades but none has been widely considered suitable for practical application. The lack of adequate countermeasures usually leads to economically-damaging bridge closures that bridge owners try to minimise through weather monitoring and ice detection ...
An experimental study on mitigating dynamic ice accretion process …
2022年4月1日 · An experimental study is conducted to evaluate the effectiveness of utilizing a superhydrophobic surface (SHS) coating to mitigate ice accretion on bridge cables and to characterize the resultant aerodynamic forces acting on …
An experimental study on mitigating dynamic ice accretion …
2022年4月1日 · In the present study, we report an experimental study to examine the effectiveness of utilizing a SHS coating to suppress/delay the icing process on typical bridge cables under different icing conditions. The experimental study was carried out by leveraging the unique Icing Research Tunnel available at Iowa State University (i.e., ISU-IRT).
(PDF) Dynamic Ice Accretion on Bridge Cables with Surface Mods
In the present study, we aim to not only reveal the transient details of the surface water transport and ice accretion on the surfaces of bridge cable models under different icing conditions (i.e., rime vs. glaze), but also evaluate the effects of different surface modifications (i.e., standard plain, pattern-indented, and helical fillet) on ...
Cable Surface for the Reduction of Risk Associated with Bridge Cable ...
2019年5月29日 · In this paper, a recently developed cable surface that can effectively reduce the risk associated with ice and snow shedding is presented. Experimental results and statistical comparisons between two different cable surfaces in ice shedding tests performed in a climatic wind tunnel are shown.
Innovative Mobile Parallel Octahedral Ice-Breaker to Remove Ice …
2022年8月24日 · The problem of ice build-up on cable-stayed bridges is addressed, and innovative ways to solve this issue are examined. The urgency to automate the process of removing ice and snow from guy lines is discussed. A new concept of an adaptive mobile parallel Octahedral Ice Breaker robot is presented to remove frozen snow and ice from guy lines.
Solutions to snow and ice buildup on Port Mann cables - Gov
A custom-designed cable sweeper has been developed that will be fitted around the bridge cables and used to remove snow and ice before it can accumulate. In addition, engineers have identified highly water repellent, or hydrophobic, coatings and de-icing sprays that could be applied to the bridge cables to further prevent the accumulation of ...
