Barrier road fences: types of structures and their use

Due to the increased accident rate on the Russian roads, thousands of citizens of our country die every year. Some of the tracks because of the constant accidents traffic police inspector and drivers are called "routes of death."

This problem needs a comprehensive solution. And one of the elements of such a solution is a barrier road fence. It is simply necessary in the organization of safe traffic.

Barrier Fence

Road Fence Functions

Such constructions implement the following functions:

• Separation of traffic - the use of these products allows you to separate the flow of vehicles and pedestrian directions. Use for this barriers made of metal or plastic. The second option applies in case of temporary measures;

Such a barrier separates flows.

• Redirection of flows - such a need arises in the case of work to repair the road in various non-standard cases.. At the same time using plastic fences, painted in a combination of white and red. Such a color scheme makes it possible to make the structure visible even in poor visibility conditions;
• Increased safety of movement - fencing extinguishes impact energy and does not allow the car to be in a ditch.

To give durability to the product, it is made of materials that can withstand temperature drops from -30? up to +40 ?. Usually it is metal. On the dangerous sections of the federal highways, it is precisely the metal barrier fencing of the highway that is installed.

Its main purpose is to prevent the departure of the car outside the track. And besides, the design allows you to extinguish the impact energy, if the car suddenly deviated from the course.

Types of road fences

Road one-sided fencing (11DO)

In the photo - the barrier 11DO

This is a barrier one-sided fence, manufactured on the basis of GOST № 26804-81. This type (11DO) is installed in those sections where the congress is a danger to transport.

This design clearly delineates the border of the road. It also prevents foreign large objects from getting into it. Therefore, 11DO is established as a mandatory element for large runs.

It includes several sections. They are installed using special fasteners and observing the desired distance.

This type of construction has a number of advantages:

1. good performance in road safety - installing these products really makes the road more secure;
2. excellent strength - this advantage is closely related to the first item;
3. Good quality materials - without it, the road barrier just won't be able to last for a long time.

Road bilateral fence (11ДД)

11DD type design drawing

The road, which has several lanes, is a zone of increased danger. In this case, bilateral barriers of the type 11ДД will help prevent accidents.

Thanks to them, the car in the event of loss of control, will not be outside the road. This will save the life of not only the driver, but also its passengers. In addition, such a barrier will avoid serious damage to the car.

Type 11DD is made according to the indicators of GOST under the number P 52289-2004, as well as GOST No. 2680486. There may be designs made according to TU under number 5216-001-70342920-2007.

The placement of fences occurs parallel to the axis of the dividing strip. Due to this arrangement, in the event of a collision with a car, metal road barriers suppress impact energy.

Bridge unilateral fencing (11MO)

Barrier construction type 11MO

Such a barrier is installed on both sides of the road on bridges, overpasses and road junctions. It allows you to very effectively prevent accidents.

These fences do not allow cars to get off the road. And in the event of a collision, they reduce the impact energy.

Type 11MO is manufactured according to GOST # 26804-86, as well as GOST # R52289-2004. In addition, it can be manufactured according to TU under number 5216-001-70342920-2007.

In addition, when creating such structures, drawings and technical conditions of the customer are necessarily taken into account. Also, it is taken into account in what conditions the product will be operated. The technical characteristics and, of course, the price of the product depend on it.

Retroreflective elements are often added to this design. They make the barriers more visible, especially at night.

Bridge fence (11 MD)

11MD type construction scheme

Barriers of this type are road fencing structures consisting of three sections. The main components in this case are the rack and console beams.

Sections of such fencing are made of a curved profile. Collect them with their own hands, fastening the design with bolts.

This ensures a reliable connection between the parts. In general, this design is quite durable and is able to provide a good level of security.

Barrier construction

Barriers consist of sections. And they, in turn, are made of beams: straight and radius long. Also the structure includes racks - road or pavement. They are called "channel".

This includes racks and elements of the initial and last section, a shock absorber console and fasteners. If necessary, the barriers can be equipped with reinforcing and retroreflective elements.

Barrier construction

Elements of sections of such a fence are made of sheet steel having a wave shape and a thickness of 3-4 mm. In the future, these steel billets covered with a layer of zinc with a thickness of eighty microns. To do this, use a method called hot-dip galvanized.

Tip! To reduce the cost of acquiring barrier structures, non-galvanized elements can be ordered. Subsequently, they can be painted. Instructions attached to the paint, will tell you how to do it correctly.

Separately, it should be noted that modern barrier fences are manufactured using the latest technologies. For their manufacture apply metal having the highest level of strength.

Plus, the above-described anti-corrosion treatment ensures a long service life of these products. For the duration of the period of use with them can be compared except that plastic nets for fencing sports fields. After all, due to galvanizing, the service life of the barriers becomes longer than when using other methods of dealing with corrosion.

Special attention should be paid to the following fact. To count on good quality and long service life of barriers is possible only in one case. If they were made in strict accordance with State Standards. Only this can guarantee the quality and safety of future structures.

Further, it is worth mentioning that in the fence pitch racks ranging from 1333 to 2250 mm. The running meter of the fence, depending on the type of fence and the pitch of the racks, can be from 30 kg to 102 kg The width of the retaining strip is 508 mm.

Quite interesting is the fact that such fences are used in more than 50 countries around the world. And, of course, they are found everywhere in the expanses of Russia.

Such barriers can be found on all routes of our country.

And this is no accident. After all, these products themselves are fully justified. They reduce the overall level of accidents on the roads.

Conclusion

Barrier fences on the roads not only separate the flow of transport and pedestrians. They in addition, provide traffic safety on the roads.

Depending on the specific road conditions, different types of fencing are applied. But they all have one common goal - reducing accidents on highways. And they successfully cope with this task.

In addition to permanent metal fences, temporary plastic barriers can be used. For example, in the production of road works.

And they can not buy, and rented. This service is also extended, as is the rental of fencing for construction sites.
