1969年我处在修建京沈线巨流河站附近辽河大桥时,在学习沈阳铁路局的经验后,采用了井点法降低地下水位开挖基础土方,建筑混凝土承台和部分墩身,以代替原设计的钢板桩围堰,因而简化了工序,大大缩短了工期。同时,采用钻孔桩基础代替沉井基础,节约了混凝土工程数量近三万立方米。井点法降水和钻孔桩均为在辽河大桥采用的新技术,也是大桥局第一次使用。我处为了系统保存资料,在绘制竣工图的同时,即对井点法降水和钻孔桩的资料进行了整理汇总,晒印成册。
In 1969, when I was building Liaohe Bridge near Jiulu River Station on the Beijing-Shenyang Line, after studying the experience of Shenyang Railway Administration, I used the well point method to lower the groundwater level to excavate the foundation earthwork, the concrete cap and some piers instead The original design of steel sheet pile cofferdam, thus simplifying the process, greatly reducing the construction period. At the same time, the use of bored pile foundation instead of caisson foundation, saving nearly 30,000 cubic meters of concrete works. Well point method of precipitation and bored piles are used in the Liaohe River Bridge of new technologies, but also the first time the bridge bureau. In order to preserve the data systematically, the drawing of the as-built drawings at the same time, that is well point precipitation and bored pile information has been collated, printed in volume.
