Study on automatic mixing system for gravel-earth material of core-wall for high earth-rockfill dam
摘要
Abstract
Aiming at the problems of lower automation level and production efficiency,larger mixing yard,poor economic benefit,etc.in the conventional technology of horizontally placing and vertically exploiting,the theory,mixing equipment,batching and measuring system of the automatic mixing system of gravel-earth material for core-wall are fully studied herein in accordance with the construction of the gravel-earth core rockfill dam with the height of 312 m for Shuangjiangkou Hydropower Station according to the reference from the mixing theory and technology of cement production,so as to enhance the mixing quality and effect of the gravel-earth material for construction of the core-wall for earth-rockfill dam,and then the design basis and parameters for carrying out the mixing by powerful horizontal mixer equipped with plough-type mixing device as well as the accurate measuring mode and the device parameters for the mixing system are put forward.It is known through the 3-D simulative analysis concerned that the production of the mixing system is 1 080 t/h,the mixing times can reach to 4,the measuring accuracy of the earth material can be controlled within 0.5％ and the measuring accuracy of the gravel material can be controlled within 1％,thus the mixing effect reach the expected goal and meet the relevant design requirement.The theory of the automatic mixing of the gravel-earth material for the construction of the core-wall for earth-rockfill dam and the design parameters of the relevant equipment are initially proposed by this study,which lays a theoretical and technical basis for mixing of the gravel-earth material for the construction of the core-wall for 300 m-grade high earth-rockfill dam and the result can provide a reference for the other similar projects as well.关键词
