环城水系是石家庄市主城区主要水系通道,主河道从既有石德铁路以框构形式通过,由于新建石济客专石家庄东站部分与既有石德线以抢修车通行线相连,设计将原有框构部分人行道悬臂切除,从切割面将剩余部分框构接长,由于框构桥尺寸过大,整体切割重量大,不宜运输,容易发生危险,如果按传统的风镐破碎施工方法,风镐破碎时所产生的剧烈震动,不仅会使被破碎断面本身受损,且会波及既有结构造成破坏,甚至影响行车安全,故采用静力切割技术进行施工。
Central city water system is the main urban water system channel in Shijiazhuang City, the main channel from the existing stone railroad in the form of frame through the Shijiazhuang East Railway Station as part of the new Shijiazhuang East Railway Station with the existing repair lines connected with the line, the original design will be the original Some of the sidewalk with framed cantilever resection, the remaining part of the frame from the cutting surface to connect the long, because the frame bridge size is too large, the overall cutting weight, should not be transported, prone to danger, according to the traditional picks broken construction method, the wind The severe vibration produced when the picks are broken will not only damage the broken section itself but also affect the existing structure to cause damage and even affect traffic safety. Therefore, the static cutting technology is used for construction.
