CALCULATION METHOD FOR DETERMINING THE STRENGTH CHARACTERISTICS OF MOBILE ROAD BARRIERS DURING THEIR INSTALLATION
This article discusses one of the problematic tasks of improving traffic safety in places of road repair work. Due to negligence or lack of requirements on the part of technical supervision in places of repair work, the risk of an accident increases from 1 to 6 or more. At the same time, one of the main reasons is the entrance to the oncoming lane, pedestrian paths or a lane under construction. The beginning and the end of the object in the places of repair work, construction contractors are "used" to fence with concrete blocks, pour high piles from the ground or other measures contrary to the standards of technical regulation in the places of road repair work. The main reason for such actions is related to the instability of mobile protective structures or inconveniences during their installation and transportation.The authors have developed a theoretical model of the stability of mobile fences and given examples of their calculation. It is based on its own model of mobile fencing. Thus, the supports of a portable temporary road fence are calculated, which increases the stability of the structure to the effects of external factors, such as: wind load, the impact of water flows from precipitation, accidental touches by road maintenance workers, etc
