  • Reducing dust pollution of the environment during a trench opening process

    The article offers a solution which will enable to reduce dust pollution during earthworks in urban conditions. A special multi-functional mechanism is proposed enabling to perform several important preliminary processes simultaneously - improving an environmental situation on the site of earthworks. The ground surface damping during trench opening and soil unloading from a bucket into a disposal area will make it possible to reduce the fine dust pollution of the air surrounding a work location. The objective of the study is to develop a mechanism reducing the fine dust dispersal when performing trench and pit excavation. The novelty is that a mechanism of special construction has been proposed that can be mounted onto any machine in the construction line.
