近年来,国内某些基本建设单位从国外订购了一些蛙式打夯机来代替土方工程中笨重的人工打夯。现将北京市道路工程局第三道路工程公司使用匈牙利小蛙式打夯机的初步经验介绍如下。北京市道路工程局第三道路工程公司,开始使用蛙式打夯机时,只跳几下就不跳了,汽油外溢,工人看着头痛,认为这种机械无法使用,还不如人工可靠。但是经一年多的摸索和使用,在工人同志的不断钻研下,除了发现机械本身有它的某些缺点外,主要还是对这种机械的操作不熟练的问题。这个机械中的某些缺点,主要是:
In recent years, some domestic construction units have ordered some frog-type tamping machines from abroad to replace bulky artificial ramming in earth-moving projects. Beijing Road Engineering Bureau now the third road engineering company to use the Hungarian frog rammer’s initial experience described below. Beijing Road Engineering Bureau Third Road Engineering Company, began to use frog-type ramming machine, only a few jumps do not jump, gasoline spills, workers looked at the headache, that this machine can not be used, not as artificial and reliable. However, after more than a year of exploration and use, under the constant study of the workers’ comrades, apart from discovering some shortcomings of the machinery itself, it is still mainly a matter of unskilled operation of such machinery. Some of the shortcomings of this machine, mainly:
