过去各设计院都编制了隧道辅助坑道方面的通用图及参考图,这些图纸在铁路隧道设计和施工方面,发挥了积极的作用。随着设计和施工技术水平的提高,特别是文化大革命以来,设计和施工单位,在采用辅助坑道方面积累了丰富的经验,原有图纸已不能适应形势发展的需要。根据原交通部(73)交铁基字781号文下达的标准设计任务,我们对原有图纸进行编制更新。在编制的新图中,着重纳入了近十年来积累起来的经验和成果,也保留了原有图纸的部分内容,同时推荐煤矿部门与此有关的部分设计内容,供设计和施工部门选用。新的隧道辅助坑道通用图(图号:肆隧
In the past, all design institutes have compiled common maps and reference maps of tunnel auxiliary tunnels. These drawings have played an active role in the design and construction of railway tunnels. With the improvement of design and construction techniques, especially since the Cultural Revolution, design and construction units have accumulated rich experience in using auxiliary tunnels. The original drawings can no longer meet the needs of the development of the situation. According to the standard design task delivered by the former Ministry of Communications (73) on the basis of Document 781, we prepared and updated the original drawings. In the new plan, the experiences and achievements accumulated in the past ten years have been mainly included. Some parts of the original drawings have also been retained. At the same time, part of the design contents related to the coal mine department are recommended for selection by the design and construction departments.
