龙溪口航电枢纽工程大体积混凝土快速入仓技术

针对岷江龙溪口航电枢纽工程混凝土工程量大、履带式布料机+反铲方式上料施工效率低、混凝土损耗大的问题，进行航电枢纽工程大体积混凝土快速入仓技术研究。通过改良入仓结构料斗的尺寸、料斗放置形式、皮带结构尺寸，采用反集料分离爬坡带进行移动输送装置、分配器垂直进料缓冲装置的布置，以及采用水平输送机、瓣膜式缓冲筒等方式的入仓装置，实现了大粒径集料混凝土的快速连续入仓。

Rapid warehousing technology of mass concrete in Longxikou Navigation-power Junction project

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.
