我公司在金陵饭店现浇混凝土主体结构施工中采用泵送混凝土工艺,泵送量1800立方米,泵送垂直高度达112米;水平泵送距离达114米。采用泵送工艺,对加快进度,保证质量,提前40天完成塔楼主体结构起了重要作用。一、混凝土输送泵的设备和性能混凝土输送泵设备利用外资引进,包括一套小型混凝土搅拌站,现将其型号及性能摘录如下: 1.混凝土输送泵输送泵型号BPA550-HD拖挂式,牌名Schwing,由西德进口。该泵工作系统有两个往复式活塞,一个在抽吸冲程中,一个在输送冲程中;有两个滑门阀,在抽吸冲程
Our company uses the pumped concrete technology in the construction of the cast-in-place concrete main structure of the Jinling Hotel. The pumping capacity is 1800 cubic meters, and the pumping vertical height reaches 112 meters; the horizontal pumping distance reaches 114 meters. The use of a pumping process has played an important role in accelerating the progress and ensuring the quality of the tower’s main structure 40 days ahead of schedule. I. Equipment and Performance of Concrete Pumps Concrete pump equipment has been introduced using foreign capital, including a small concrete mixing plant, and its model and performance are now extracted as follows: 1. Concrete pump pump model BPA550-HD trailer, brand Schwing, imported from West Germany. The pump working system has two reciprocating pistons, one in the suction stroke and one in the delivery stroke; there are two slide gate valves in the suction stroke
