Aiming at the problems of large amount of concrete works,low construction efficiency of crawler type spinner + backhoe loading and large concrete loss in Longxikou Navigation-power Junction project in Minjiang River,we study the rapid warehousing technology of mass concrete in navigation-power junction project.We improve the hopper size,hopper placement form,belt structure size,use the mobile conveying device through reverse aggregate separation climbing belt,distribution vertical feed buffer arrangement,and adopt the warehousing device by means of conveying,horizontal conveyor,valvular buffer cylinder,etc,which realize the rapid and continuous warehousing for large aggregate particle concrete.
