第二铁路工程局桥工大队在新线工程中担任了十二座大桥的施工任务。过去,由于路线斗爭觉悟不高,抓了多快,忽略了好省。所以去年七月份前完工的大桥,大部分仍是采用塑性混凝土施工,给国家造成很大的浪费。 1971年5月,桥工大队首先在长辛寨大桥开始推行干硬性混凝土施工,以后逐漸在全大队推广。到目前为止,共完成千硬性混凝土11,152立方米,节约水泥305.5吨。在推行干硬性混凝土施工时,遇到了“唯条件论”、“因循守旧”等错误思想。有人说:“虽然我们过去在抽动钢模采用过半干硬
The Bridge Engineering Brigade of the Second Railway Engineering Bureau served as the construction task for the 12 bridges in the new line project. In the past, due to the low awareness of route struggles, how fast they were caught and neglected good provinces. Therefore, most of the bridges completed before July last year were still constructed using plastic concrete, causing great waste to the country. In May 1971, the bridge workers team first began to implement dry-hard concrete construction on the Changxinzhai Bridge, and gradually spread it throughout the brigade. So far, a total of 11,152 cubic meters of concrete has been completed, saving 305.5 tons of cement. In the implementation of dry and hard concrete construction, we encountered the wrong ideas such as “conditionalism” and “observing the old”. Someone said: "Although we used to use semi-rigid steel
