丰台桥梁工厂在深揭狠批“四人帮”,开展“工业学大庆”群众运动中,在北京市建筑工程研究所协助下,试制成功我国第一台挤压式混凝土输送泵。混凝土输送泵是利用管道输送混凝土拌合料的主要设备。在混凝土工程施工中,泵管运输混凝土效率高,劳动强度低,安全可靠。尤其在混凝土用量大、施工场地狭窄及高大建筑物的施工中具有突出的优越性。几十年来,国外相继试制发展这项技术,泵送混凝土占商品
The Fengtai Bridge Factory tried out the first extrusion concrete pump in China with the help of Beijing Institute of Building Engineering in carrying out the “Gang of Four” in the deep exposing to the “gang of four”. Concrete pump is the use of pipe concrete mixing material of the main equipment. In concrete construction, pump pipe transportation of concrete, high efficiency, low labor intensity, safe and reliable. Especially in the large amount of concrete, the construction site is narrow and tall buildings in the construction of outstanding advantages. For decades, foreign countries have trial-produced to develop this technology and pump concrete products
