随着建筑市场的蓬勃发展和施工机械的科技进步,钻孔灌注桩的应用规模越来越大,使用传统的人工方法灌注混凝土,已经远远不能满足施工的需要。特别是一些场地局限性较大、起重设备不能进入的工地,仅靠人力小推车装运混凝土,不但施工效率低、劳动强度大,而且难以保证工期。随着施工机械化程度提高,混凝土输送泵的使用越来越广泛。由于一些施工队伍对混凝土输送泵 With the vigorous development of the construction market and the scientific and technological progress of construction machinery, the application of bored piles has become larger and larger. The use of traditional artificial methods to pour concrete has been far from meeting the needs of construction. In particular, some venues with large limitations, lifting equipment can not enter the site, relying on manpower carts transport concrete, not only low construction efficiency, labor-intensive, but difficult to guarantee the construction period. With the improvement of construction mechanization, concrete pump is used more and more widely. Due to some construction teams on the concrete pump
