PROPOSALS FOR DEVELOPING A UNIFIED APPROACH TO ASSESSMENT OF FUNCTIONAL PROPERTIES OF DOMESTIC-PRODUCED SWEEPERS

Abstract

Maintenance of city streets and roads is an integral part of the road infrastructure operation. The main task of summer roads cleaning is to remove all types of pollution that accumulate on a roadway surface, sidewalks, public transport stops, which are a source of dusty air and littering urban areas. Regulatory documents are introduced in different countries with the roads maintenance requirements. First of all, the mechanized sweeping quality depends on the machines sweeping efficiency indicators level.

Analysis of information resources showed the lack of a unified approach to determining the quality indicators of mechanized street sweeping. This makes it impossible for consumers to compare and choose new street sweepers.

This paper proposes a methodology for testing street sweepers. To simulate the most common types of garbage on the road, it was proposed to use sand, crushed stone and sawdust from wood production as a typical test material.

The developed technique was tested during testing of a new sweeping machine КВСЗ-4002 produced by “Kryukovsky Railway Car Building Works”. The carried out tests have shown the possibility of using this technique to determine the cleaning efficiency coefficient (cleaning efficiency) and other indicators of a sweeping machines work quality. The proposed sweepers testing method can be considered as a solution of the problem of typing different street pollution types.
