基于起重、运输技术的新型交通体系的构建

目前对城市交通系统的能力要求越来越高,城市规划、土地、资金等的约束对城市交通体系的建设影响较大。本文提出了基于现代起重、运输技术的新型交通体系的构建理念,设计了针对车辆掉头、紧急事件处理、潮汐交通等方面的专用设备,有效提升了交通系统的通行能力。     

不锈钢冷轧基础螺栓安装技术

酒钢不锈钢冷轧二期大冷线基础分9块,全长270 m,底部标高最深为7.6 m。基础螺栓标高大致分三层近千根,由于设备安装精度要求高,螺栓相对尺寸及总尺寸的安装精度同样要求十分严格。为了保证螺栓的安装精度,从测量控制、螺栓固定架安装、螺栓安装、混凝土浇筑等几个方面进行了严格的控制。特别是定位控制,采用长短线相结合的方法,利用全站仪进行有效的控制,满足了规范的相关规定。     

A survey of anthropometry of rural agricultural workers in Enugu State,south-eastern Nigeria

In developed countries, large amount of anthropometric data are available for reference purposes; however, anthropometric data of Nigerian populace are lacking. As a result, most agricultural machines and equipment used are designed using anthropometric data from other populations of the world. A total of 377 rural agricultural workers within the age limit of 18–45 years, who are involved in different agricultural activities, were selected from six rural agriculture-based communities in Enugu state. Thirty-six anthropometric body dimensions were measured including age and body weight. A comparison between the male and female data indicated that data obtained from male agricultural workers were higher than that obtained from their female counterparts in all body dimensions except chest (bust) depth, abdominal breadth and hip breadth (sitting). In terms of design parameters, it was observed that the data from Nigerian agricultural workers were different from that obtained from agricultural workers in north-eastern India.

Practitioner Summary. Anthropometric data of Nigeria populace are lacking. As a result, most agricultural machines and equipment used are designed using anthropometric data from other populations of the world. It was observed that the data from Nigerian agricultural workers were different from that obtained from agricultural workers in north-eastern India.
