FIELD STUDIES--INNOVATIVE SAFE EXCAVATION TECHNOLOGIES

说明： 这项建议的目标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 建筑。这项研究是在NIOSH授予的5 R01 CCR413051-02资助下进行的 成功论证了安全开挖的可行性和适用性 还有管道铺设。这项研究使原型技术和 在实际建筑工地上进行了全尺寸的现场试验 使用施工人员。从吸取的教训、新的问题和进一步的 出现了一些研究课题。这项研究的总体目标仍然存在，但 并扩展了先前的工作。为了进一步实现这些目标， 将实现以下具体目标：扩大联合国系统的能力 挖掘机安装的埋地公用事业检测系统(EMBUDS)目前能够 定位金属管和电力线，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 (管道人)关于远程放置床上用品；设计和制造一个较小的 《皮皮曼》(小皮皮曼)可以铺设较小的管道，如聚氯乙烯和 并对钢管的连接问题进行探讨。 与混凝土管道不同的要求；集成扩展的EMBUDS 改进了EMBUDS的人机界面， 和小皮普曼；在现场演示技术；并传播 通过期刊文章、会议论文和网站上的信息。

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.
