苏联勃良斯克《土壤改良机械》联合总厂研制了渠道混凝土浇筑用的自走式联合试验样机,并进行了试验。联合浇筑机包括断面挖掘机、混凝土浇筑机、接缝切割器和修整装置。联合浇筑机每小时浇筑混凝土90立方米,其浇筑能力几乎比老式浇筑机高一倍。其重要特点 Soviet Union Bryansk “Soil Improvement Machinery” Joint General Plant developed a self-propelled concrete pouring channel test prototype, and conducted a test. Combined casting machines include section excavators, concrete pouring machines, seam cutters and trimming devices. Concasting machines pour 90 cubic meters of concrete per hour, giving them almost twice as much pouring capacity as older pouring machines. Its important features
