Different Types Of Protection Systems - 727 Words

These protection systems either helps in capturing the rocks or to control their trajectory once it has fallen down, they are of following types : Rigid barriers Flexible barriers Attenuator system Catch areas Rock sheds Rigid barriers: These barriers are constructed to either contain or deflect the rockfall as these structures are so stiff that they can easily withstand the kinetic energy impacted by the falling boulder with very less or no deformation. So they are mainly constructed near the disaster place. Catch areas: These are used to stop the capture falling rocks before they cause risk to the structure. They are usually constructed along the transportation routes. Flexible barrier : These barriers are the lightweight barriers†¦show more content†¦Design ( flexible barrier) : The design approach for the flexible barrier is the most developed part of all the rock fall protection system as it involves the design approach ( MEL SEL), corrosion protection of the fence, downward deflection of the fence, sizing of the fence. These all aspects helps to get a better design of the fences which can withstand very harsh and aggressive environment. MEL (Maximum energy level): This energy level fence is used at the site where the occurrence of the rockfall is very low so after the impact with the fence ie. when a boulder hits the fences there is a need for the repair or the replacement of the fence as the barrier have to catch a boulder with a maximum energy level of 100% and the residual height after the impacts shows the quality of the barrier. SEL (Service energy level): This is the type of the fences in which the barrier has to catch the two impacts of the boulder with â…“ of the MEL energy being damaged. These type of fences are used where the occurrence of the rockfall is more. After the first impact of the boulder, the residual height should be greater than 70% so that the fence can take the second impact which is just to catch the boulder. Flexible barrier size selection : The selection of the size basically depends uponShow MoreRelatedVirtual Electrical Panel For Ultra Modern Buildings And Industries Essay1130 Words   |  5 Pageselectrical protection are becoming more complex and costly also.

The fundamental principle of distance relaying is based on the local measurement of voltages and currents, where the relay responds to the impedance between the relay terminal and the fault location [1]. There are many types of distance relay characteristic such as mho, reactance, admittance, quadrilateral polarized-mhoRead MorePrinciples Of Business Document Production And Information Management990 Words   |  4 PagesUnit 03: Principles of Business Document production and Information Management 1.1 Describe different types of business documents that may be produced and format to be followed for each?

It’s the first line of defense against malware. An organization can not protect their network with just a firewall. Additional protection is needed to avoid potential risks and attacks. An Intrusion Prevention System adds the extra layer of protection by examining all network traffic that is allowed through the firewall. Previously Intrusion Prevention Systems simply protected operatingRead MoreChild Protective Services1477 Words   |  6 PagesCHILD PROTECTIVE SERVICES REFORM 1 INTRODUCTION Child Protective Services (CPS) is a complex system of assessments, investigations, and conclusions.
