Classification of corrugations: which option to choose

When working on the arrangement of the road surface, corrugation is indispensable – machines evenly applying layers of tar and bitumen on the processed surface of the road. There are three varieties of cornflowers – small corrugations, handed by hand, used as trailers and corrugated gurodnators with a car -basis with sports fraud so that there was where to cling to the trailer. The simplest device has manual corrugations, they consist of a tank with a capacity of up to half a ton of liters, a pump, a metal flexible sleeve and a manual distributor with one or three nozzles.

Manual corrugations are used for small volumes of work where the use of large equipment is difficult or inappropriate. Precedented corrugated gurodnators are used as trailers for autobitum trucks. They are equipped with devices for pumping and distributing bitumen or tar.

The most difficult type of cornfields are auto connectors. They are equipped with a mechanical bitumen distribution system. Motor monitors are used on time of such road works that require impregnation, drainage, surface processing and preparation of Bitumen and tar mixtures directly during the work.

Auto -connectors have a significant tank capacity (up to seven tons), and the tank has a heating system for the suitable mixture. The distribution system is acted by either an autonomous engine, or it is possible to use part of the power of the engine of the machine.

Auto-controllers are equipped with instrumental devices that allow you to monitor the process of work performed. Motor monitors retain the necessary parameters of the bitumen mixture, regardless of external conditions, and also have the ability to automatically clean the system of distribution of the bitumen mixture.

This object has such a fate that involuntarily allocates it among others in Kazakhstan. The bridge across the Ural River in the administrative center of the West Kazakhstan region began to be built in the “good old days”, that is, under the Soviet regime. Since the republic never had their own organizations specialized in this case, bridge builders from different Russian cities worked here here. Then there was a notorious “parade of sovereignty”, followed by an economic crisis. Although the construction of the bridge continued, however, the payment of the executed volumes was now constantly delayed, or even at all moved away for an indefinite period. For this reason, the bridge builders stopped working several times. However, the object in Uralsk is one of the most significant in Kazakhstan, and therefore did not forget about it: the press periodically woke up this topic. Increased attention is also explained by the fact that the bridge across the Urals does not just connect the two banks of the river, it makes up an important link on the shortest path from Central Asia to the European part of Russia. As a result, the story of the invitation of bridge builders from a neighboring state was repeated again and again, without a visible result. There is a rather funny moment in it. A couple of years ago, when the President of Kazakhstan Nursultan Nazarbayev arrived in Uralsk, the local authorities invited him to take part in the solemn open… bridge over the Urals. The head of state made sensory words and cut the red ribbon. But when the ceremony ended and the president left, the entrance to the bridge was closed. The fact is that every driver who would decide to update the shortest path from Central Asia to Russia could well have been on the other side, but at the bottom of the river. The object was not over. And the main difficulty was not so much in building a car transition through the Urals itself, but in the construction of multi -kilometer approaches to it through a constantly flooded floodplain. And work here still start and finish. And now in the republic they decided to return to the long -suffering object again. The Ministry of Transport and Communications of the Republic of Kazakhstan announced the competition for state procurement of works and services for the reconstruction of the bridge over the Ural River. The required delivery time within 2000. Potential suppliers who meet the qualification requirements stipulated in Article 10 of the Law of Kazakhstan “On public procurement” are allowed to the competition.
