带布料杆的混凝土输送泵车,由于具有泵送性能好、布料范围大、能自身行走和转运方便等优点,近年来已成为各国泵送混凝土施工的主要机具。上海宝钢工地从日本引进的三菱“DC—S115B”型和石川岛播磨重工“PTF—7SBZ”型混凝土泵车,使用五年来已顺利完成宝钢一期工程大型设备基础等混凝土浇灌任务,累计泵送混凝土达160多万米~3,对工程的顺利进展起到了重要作用。采用上述两种泵车,可以一次同时完成现场混凝土的输送和布料。在施工组织合理和泵车运转正常情况下,泵送效率约在30米~3/小
Concrete pump trucks with distribution poles have become the main equipment for pumping concrete construction in various countries in recent years due to their advantages of good pumping performance, large fabric range, and their ability to walk and transport themselves. The Mitsubishi “DC-S115B” type imported from Japan at the Shanghai Baosteel site and the “PTF-7SBZ” concrete pump truck from Ishikawajima Heavy Machinery Co., Ltd. have successfully completed the concrete watering tasks such as the large-scale equipment foundation for the first phase of Baosteel’s first-phase project in five years, and accumulated pumping. Concrete more than 160 million meters ~ 3, played an important role in the smooth progress of the project. With the above two pump trucks, the on-site concrete transportation and cloth can be completed at the same time. Under the conditions of reasonable construction organization and normal pump operation, the pumping efficiency is about 30 meters~3/small
