Abstract

At present, most of road reinforced concrete fencing is erected by the sliding formwork method. It is being applied more and more widely. The advantage of the continuous shaping method is a smaller number of workers occupied in the formwork construction and concrete laying and shorter duration of concreting. However, the existing fencing technologies with reinforced concrete have drawbacks that do not allow achieving the required quality of these products, namely, incomplete processing of concrete in the bottom part of the barrier structure (caving) and deposition of the freshly laid barrier under the effect of vibrations transmitted through the foundation.
This explains the importance and relevance of studies aimed at improving the quality and reliability of reinforced concrete barriers on bridges that are built by the sliding formwork method, since bridge structures are subject to higher requirements for strength, durability, and resistance to water and frost.
