Metro operation line viaduct train shaking supporting block transformation method
The invention relates to the technical field of engineering science, in particular to a metro operation line viaduct train shaking supporting block transformation method which comprises the following steps that existing supporting block short sleepers are removed; a new prefabricated supporting block short sleeper is installed; and the quick-hardening cement mortar and water are stirred, and pouring is conducted. According to the method, in a train stopping time window, a short sleeper embedded in an existing supporting block is chiseled away, a new prefabricated short sleeper is installed, the geometric dimension of a rail is adjusted, fast-hardening mortar is poured, the steel rail is relocked, site garbage and tools are cleared away, and the site state and the rail state are checked so as to meet the operation condition of the next day. Compared with the prior art, the method has the advantages that the step of chiseling away the existing ballast bed concrete in a large area is omitted, the transformation construction technology is high in efficiency, and the influence on normal train operation is small. According to the metro operation line viaduct train shaking supporting block transformation technology, new prefabricated supporting block short sleepers are adopted, and what can be guaranteed is that the geometric dimension of a track meets the requirement.
本发明涉及工程科学技术领域，具体来说是一种地铁运营线高架桥列车晃动支承块改造方法，所述的方法如下：去除既有支承块短轨枕；安装新的预制支承块短轨枕；将快硬性水泥砂浆与水搅拌后进行浇筑。本发明在列车停运时间窗口，把既有支承块预埋的短轨枕凿除，安装新的预制短轨枕，调整轨道几何尺寸，浇筑快硬型砂浆，重新锁定钢轨，清理现场垃圾和工具，检查现场和轨道状态以满足第二天运营条件，同现有技术相比，其优点在于：减少了大面积凿除既有道床混凝土的步骤，该改造施工技术效率高，对正常列车运营影响小。地铁运营线高架线列车晃动支承块改造施工技术，采用新的预制支承块短轨枕，能保证轨道几何尺寸满足要求。
