一、概述近十多年来,我国钢筋砼管、预应力砼压力管、高强度砼桩以及其他砼制品的研究、生产和应用虽然取得较大进展,但与国外先进水平相比,尤其在技术、工艺、设备、标准、管理和质量控制等方面均有较大差距。在当前“改革、开放”政策指引下,引进必要的先进工艺和设备,是提高我国砼制品质量、改造现有工艺和设备、缩小差距和提高经济效益的一条行之有效的途径。株洲水泥管厂从瑞典引进了逊他布管技术,整个引进工作分四个阶段:第一阶段对于全部引进资料的翻译、消化、吸收与评价;
I. Overview In the past decade or so, China’s research, production, and application of reinforced concrete pipes, prestressed concrete pressure pipes, high-strength concrete piles, and other concrete products have made great progress, but compared with advanced foreign standards, especially There is a wide gap between technology, technology, equipment, standards, management, and quality control. Under the guidance of the current “reform and opening up” policy, the introduction of necessary advanced technology and equipment is an effective way to improve the quality of our country’s antimony products, transform existing technologies and equipment, narrow the gaps, and increase economic efficiency. The Zhuzhou Cement Pipe Plant has introduced the Sonchab tube technology from Sweden. The whole introduction work is divided into four stages: the first stage is the translation, digestion, absorption and evaluation of all imported materials;
