FIELD STUDIES--INNOVATIVE SAFE EXCAVATION TECHNOLOGIES

产品说明： 本提案的目的是评估新的挖掘技术， 承诺从根本上减少与反铲挖掘有关的几个危险， 建设本研究在NIOSH批准的5 R 01 CCR 413051 -02下进行 成功论证了安全开挖的可行性和适用性 和管道铺设。这项研究“加固”了原型技术， 在实际的建筑工地上， 使用建筑人员。从吸取的教训、新的问题和进一步的 研究课题已经出现。研究的总体目标仍然存在，但 这是对以前工作的延伸。为了进一步实现这些目标， 将努力实现以下具体目标： 挖掘机安装的地下设施检测系统（EMBUDS）目前能够 定位金属管道和电力线，以便能够定位塑料 和混凝土管道;解决管道操纵器提出的问题 （PIPEMAN）关于远程设置床上用品;设计和制作一个较小的 派普曼（PIPEMAN Jr.）可以铺设较小的管道，如PVC， 钢管和调查的问题，连接的管道，有很大的 与混凝土管道不同的要求;集成扩展的EMBUDS 小派普曼改进EMBUDS、PIPEMAN、 和小派普曼，在实地展示技术; 通过期刊文章、会议论文和网站提供信息。

DESCRIPTION: The objective of this proposal is to evaluate new excavation technologies that promise to radically reduce several hazards related to backhoe excavation in construction. The research performed under grant 5 R01 CCR413051-02 from NIOSH successfully demonstrated the feasibility and applicability of safe excavation and pipe laying. The research "ruggedized" the prototype technologies and demonstrated each as full-scale field experiments on actual construction sites using construction crews. From the lessons learned, new questions and further research topics have arisen. The overall goals of the research still remain but with an extension of the previous work. In order to further achieve the goals, the following specific aims will be pursued: extend the capabilities of the Excavator Mounted Buried Utility Detection System (EMBUDS) presently capable of locating metallic pipes and power lines to have the ability to locate plastic and concrete pipes; address the questions raised with the pipe manipulator (PIPEMAN) about remotely setting the bedding; design and fabricate a smaller version of PIPEMAN (PIPEMAN Jr.) that can lay smaller pipes such as pvc and steel pipes and investigate the issues of jointing the pipes which have very different requirements than the concrete pipes; integrate the expanded EMBUDS and PIPEMAN Jr.; improve the human machine interfaces of the EMBUDS, PIPEMAN, and PIPEMAN Jr.,; demonstrate technologies at field sites; and disseminate information via journal articles, conference papers, and on a website.
