在土方施工中,如果先使用松土器将土壤翻松,再进行推土、铲运或装载作业,可明显地提高生产率,降低施工成本和提高施工安全性。据有关资料介绍,在同样施工条件下,使用松土器参加施工,可使施工成本降低50%。在开挖硬土中使用松土器,比钻眼爆破作业施工有明显的优越性。据苏联资料介绍,在秋明——苏尔古特铁路建设中,采用钻眼爆破作业的生产率为31.6m~3/h,而用松土器作业的生产率则为265m~3/h。
In earthwork construction, if the soil is loosened first using a ripper, then the earthmoving, scraping or loading operation can significantly increase the productivity, reduce the construction cost and improve the construction safety. According to the relevant information, under the same construction conditions, using ripper to participate in the construction can reduce construction costs by 50%. The use of ripper in excavation hard soil has obvious advantages over drilling and blasting operations. According to Soviet data, in the construction of the Tyumen-Surgutt Railway, the productivity of drilling and blasting operations was 31.6 m 3 /h, while the productivity of ripper operations was 265 m 3 /h.
