It is often necessary to use barricades and barriers in different situations. They can be used to prevent access to restricted areas or to ensure that vehicular and pedestrian traffic moves in specific directions.
Often we see barricades being used to cordon off construction sites. In such cases crowd concrete barriers are used to promote safety and to ensure that visitors do not inadvertently move into risky areas. Also, when a special event takes place – say for a public meeting or sports meet – it becomes necessary to use barriers to ensure that the traffic moves in the right direction. In the absence of such barricades, an ugly traffic jam could result very quickly.
We have seen some examples of barriers being used as temporary measures. Similarly, on highways, there is often construction work going on, and it becomes necessary to cordon off a part of the highway to direct or restrict traffic. In such cases, highway concrete barriers are used for great effect. These measures can be temporary and the barricades can be removed as soon as the event is over, or the construction work is complete. Even on a regular or ongoing basis, people often use barriers to block access to certain areas. Barricades are also used to great effect as road dividers, and this can be for a long term.
There are several other uses to which concrete barriers have been put. For example, they can be used to block or stop out of control vehicles, or vehicles which are being chased. A barrier strategically placed in the path of the vehicle can bring the vehicle to a stop. These barriers can also be used to shore up sand piles or piles of debris.
Jersey barriers, as they are commonly called have also been used to great effect as noise control agents, particularly in construction sites. In a construction site, noise is a part of the scheme of things. If these barriers are placed strategically around the noise pollution area, they tend to absorb much of the noise and thus act as sound control agents.
These barriers have their origin in the construction industry and are produced in many different designs to suit specific requirements. However, their use has spread out much wider than just the construction industry, into many different areas of life. Construction barriers are indeed a great boon to many industries and businesses.
