本期刊登的“某线两座隧道整体道床施工技术介绍”,就“预制块式”整体道床的施工概况、施工方法及施工组织等问題做了全面介绍,可供有关单位参考。在毛主席的革命路线指引下,近几年来,全国已修建了近数百公里的整体道床线路,在设计、施工、养护维修方面积累了不少经验,但是也存在不少问題。如钢轨扣件及道床结构型式、施工机具等尚未定型;道床设计中对基础处理不当,运营后产生病害,不仅不能方便养护维修,而且给养护工作带来很多困难;在多快好省地修建整体道床工作中如何突出“快”字,提高施工速度,都需逐步解决。本刊将陆续刊登介绍“整体道床”设计、施工、养护维修等方面经验的文章,欢迎踊跃投稿。
This issue of “a line of two tunnels overall track bed construction technology introduction”, on the “prefabricated” overall track bed construction overview, construction methods and construction organization issues such as a comprehensive introduction for the reference of the relevant units. Guided by Chairman Mao’s revolutionary line, in recent years, the country has built hundreds of kilometers of total track bed lines, and has accumulated considerable experience in the design, construction and maintenance of maintenance. However, there are still many problems. Such as rail fasteners and track bed structure type, construction machinery and so on have not yet been finalized; improper basic handling in the ballast bed design and disease after operation not only fail to facilitate maintenance and repair, but also bring a lot of difficulties to maintenance work; How to highlight the “fast” word in the overall work of track bed, improve the construction speed, need to be gradually resolved. Articles will be published in succession to introduce the “overall track bed” design, construction, maintenance and other aspects of the experience of the article, are welcome to submit.
