Sub-dam construction method of Bayer process red-mud dry-stacking field
A Bayer method of red mud and sub-dam technology, which is applied in chemical instruments and methods, filling, construction, etc., can solve the problems that are not suitable for sub-dam construction, and the dam slope ratio of sub-dam construction methods cannot be applied with empirical data, etc. Achieving the effect of large storage capacity

 Embodiments of the present invention: as attached figure 1 As shown, firstly, prepare the dam-building materials, and select the red mud that has been turned in the red mud layer of the storage yard and has a water content of 25% to 35%, and transport it to the sub-dam to be constructed with bulldozers, excavators and other machinery. Pile nearby and take measures (such as discharging a small amount of red mud on the surface) to protect it to maintain its water content.
 Secondly, strengthen the dam foundation of the sub-dam. Sub-dam 1 is located on the red mud layer, and the red mud layer is used as the foundation of the sub-dam. First use bulldozers to break the red mud layer within the scope of the dam foundation 2 and perform preliminary rolling operations, and then use a vibratory roller to further compact it until the water content of the red mud within the depth of 3m within the scope of the dam foundation reaches 35% or less. When the dam foundation reinforc...
