光孔上螺桩无切削工艺,是五机部的工人同志在一九六四年创造出来的。一九六五年庆安公司等单位学习五机部的先进经验,开始了光孔上螺桩的试验研究和推广工作。近几年采,光孔上螺桩新工艺在我部所属工厂应用日益广泛,收到了很好的效果。今年九月在长沙召开的部标准审定会上,到会同志一致认为光孔 上螺桩是一项先进的工艺方法,。艺简单,经济效果显著,并建议把它作为指导性 技术文件颁发。国外关于光孔上螺桩的介绍,一九七O年第一次在苏联有共杂志上 出现。文章。光孔上螺桩和螺套>>是我们看到的第二篇,内容比较简单,没有实验 数据,安装方法落后,在理论、实践及使用效果方面没有谈及更多问题。现把它翻 译刊登,供大家参考。 No holes on the screw pile cutting technology, is the workers of the five ministries in 1964 to create a comrade. In 1965, Qing’an Company and other units learned the advanced experience of the Fifth Machinery Department and started the experimental research and popularization work on the upper screw hole of the light hole. In recent years mining, the new technology of optical fiber screwdriver in my department owned factories are increasingly widespread, received good results. At the ministerial review meeting held in Changsha in September this year, comrades in the meeting unanimously considered that the light-hole screw-pile is an advanced technological method. The art is simple and economical, and it is recommended that it be presented as a guiding technical document. The introduction of the optical fiber jacking piles abroad first appeared in a total of 20 magazines in the Soviet Union in 1970. article. Light hole screw pile and screw >> is the second we see, the content is relatively simple, there is no experimental data, the installation method is lagging behind, in the theory, practice and use of effects did not talk about more problems. Now translate it published for your reference.
