吉林四平地区桥梁工程队,在一座中型桥梁施工中,发扬了自力更生、奋发图强、勤俭建国的革命精神,打破了不宜用自落锤打钢筋混凝土桩的框框,为目前尚不具备汽锤或柴油打桩机修建钢筋混凝土排架桩墩台的桥梁,提供了简易、价廉、有效的机械。过去打钢筋混凝土桩只有用双动、单动汽锤或大型柴油打桩机,现在工地没有这种设备。他们就认真、仔细地研究了打钢筋混凝土桩不宜用自落锤的原
In the construction of a medium-sized bridge, the bridge engineering team in Siping District of Jilin carried forward the revolutionary spirit of self-reliance, work hard and thrift to build a nation, breaking the box frame which is not suitable for self-descrambling and hammering of reinforced concrete piles. As a result, The machine builds the bridge which the reinforced concrete arranges the pile pier, has provided the simple, the cheap, the effective machinery. In the past it was not possible to work on reinforced concrete piles with double acting, single acting hammer or large diesel pile driver. They carefully and carefully studied the original use of self-falling hammer should not hit the reinforced concrete piles
