Rapid removing of compressed snow on urban roads has been a problem difficult to solve. There is no efficient and practical machine for it presently. Three types of snow removing mechanisms are described in this article and their performance and characters are evaluated through tests. 城市道路压实积雪的快速清除一直是较难解决的问题.目前,仍没有高效实用的除雪机械。本文分别介绍三种不同除雪机构通过试验对其性能及特点作出评价。 Cleaning compacted snow on road in city is a problem which has not beensolved. Now,cleaning compacted snow is still manually. In recent years,although a few kinds ofmachines used for cleaning snow were desinged out,they have not been produced as products forsome reasons. Some viewpoints about the presence and development of cleaning compacted snowin our contry are figured our and two kinds of machines used for cleaning snow are introduced inthis paper,Some information abroad is introduced,too. 在我国,城市道路压实积雪的清除一直是一个没有很好解决的问题.目前除雪工作仍要靠人工劳动.近几年虽然先后有一些除雪机问世,但由于种种原因并没有形成产品投入生产和使用.本文对我国目前除雪工作现状及发展提出几点看法,同时对国外情况作一简单介绍. Road compaction machinery is one of main machinery in road construction,the paper main discusses the situation and technical development of the machinery. 道路压实机械是筑路工程中主要机械之一,本文主要阐述此类机械的现状及技术发展趋势。
