“轻型振动成孔机”的研制是国家建委下达的一项专题任务,在湖南省建委的主持和国家建委建筑科学研究院的协助下,由湖南省第四工程公司和湖南省常德工程公司承担其研制任务。他们以阶级斗争为纲,坚持党的基本路线,加强党的领导,大搞群众运动,发扬自力更生、艰苦奋斗的精神,经过一年多的努力,分别研制出“A-1型12吨轻型振动成孔机”和“ZKⅠ、Ⅱ型振动成孔与螺旋钻孔二用机”的样机,并进行了初步工程考核试验。 湖南省建委与国家建委建筑科学研究院于今年3月2日至9日分别在邵阳、常德召开了“轻型振动成孔机”评议会。 会议认为,这两种样机构造简单,操作简便,工效较高,易于制造,适用于丘陵地区和湖区的回填土和淤泥软弱地基的基础施工,不受地下水位高低的限制,可以为保证工程质量,减轻劳动强度,提高基础施工机械化水平和缩短工期创造条件。 样机还存在一些不足之处,如机底盘刚度较弱、机架稳定性不足、成桩的质量及其承载能力的检查与试验等,均需不断改进,积累资料,总结经验,使其逐步得到完善。 The development of “light vibration machine” is a special task issued by the National Construction Committee. Under the leadership of the Hunan Provincial Construction Committee and the assistance of the National Construction Engineering Academy of Construction, the fourth engineering company of Hunan Province and Changde Engineering Co., Ltd. of Hunan Province shall bear the responsibility. Its development task. They took the class struggle as the key link, upheld the party’s basic line, strengthened the party’s leadership, vigorously promoted mass movements, and carried forward the spirit of self-reliance and hard work. After more than a year’s hard work, they developed the “A-1 12-ton lightweight vibration. The prototypes of the “hole-forming machine” and “ZKI, II-type vibratory drilling and auger drilling machine” were carried out, and preliminary engineering assessment tests were conducted. The Hunan Provincial Construction Commission and the National Academy of Construction Research Institute held the “Light Vibration Machine” council in Shaoyang and Changde from March 2 to 9 this year. According to the meeting, the two prototypes are simple in construction, easy to operate, and highly efficient. They are easy to manufacture. They are suitable for the foundation construction of backfill soil and soft silt foundations in hilly areas and lake areas. They are not limited by the level of groundwater level and can guarantee the quality of the project. , Reduce labor intensity, improve the level of basic construction mechanization and shorten the time limit to create conditions. The prototype also has some deficiencies, such as weak chassis stiffness, lack of rack stability, inspection and testing of the pile quality and its carrying capacity, etc., all of which need to be continuously improved, accumulate data, summarize experience, and gradually obtain perfect.
