Sand drain material and material for sand compaction pile using iron and steel slagPROBLEM TO BE SOLVED: To provide a material using steel slag for sand drainage and sand compaction pile, which has non-consolidation properties and water permeability.篠崎 晴彦...
Recovery of winter sanding material from the highway is designed to be a joint effort of surface runoff and sweeping machines. As a tradeoff exists between sand recovery and the size of a snow storage area, this study also presents a maximization methodology by which the size of the snow ...

accomplished by conveying the product from the washer tub up the inclined dry deck area, which allows much of the free water to drain from the material. The use of a close-clearance curved plate on one side of the dry deck area and a drainage trough on the other also aids in dewatering...
Particle size is important, as sand toosmall in particle size will hold water well, and large particle size is notcomfortable for cows to lie on. Very fine sand provides less drainage becausethe fine sand fills voids between larger particles and allows pooling orpockets of moisture. A depth ...

For example, in the United Kingdom industry, “sand” refers to (noncohesive) minerals with a mean grain size lying between 0.63 and 5 mm, and “gravel” is reserved for coarser material; in Belgium, the industry considers as gravel the sediment with a mean grain size larger than 4 mm...
≤ 50–75 m depth), much deeper deposits (> 75 m depth) are also found that require alternative methods of extraction, such as Steam-Assisted Gravity Drainage (SAGD), which is an enhanced oil recovery technology involving an advanced form of steam stimulation (Foght et al., 2017; Gates ...
