    • PROBLEM TO BE SOLVED: To provide a method for rapidly reducing flowability of foam soil without using a defoaming agent.SOLUTION: A method for processing foam soil comprises an initial step 102 and a subsequent step 104. In the step 102, the excavation soil produced by a foam shield construction is fed into a fracturing and foam breaking facility 11, so that the excavation soil is fractured and the foam in the excavation soil is broken. The bearing effect of the foam is thus eliminated, and the size of clod is reduced by the fracture of the excavation soil in the case of viscous soil. Consequently, a surfactant as a raw material of the foam can easily adsorb to soil particles. In the step 104, activated carbon is fed into the processed soil with broken foam. The activated carbon is uniformly dispersed in the processed soil of sandy soil and even of viscous soil due to the markedly-reduced size of the clod constituting the processed soil. The surfactant in the processed soil is thus efficiently adsorbed to the activated carbon. Disposal of waste soil including transportation and loading is more easily performed.
    • 要解决的问题:提供一种快速降低泡沫土流动性而不使用消泡剂的方法。 解决方案:一种处理泡沫土的方法包括初始步骤102和随后的步骤104.在步骤102中,通过泡沫防护结构产生的挖掘土壤被输送到压裂和泡沫破碎设施11中,使得 开挖土壤断裂,开挖土壤中的泡沫破裂。 因此消除了泡沫的轴承效应,并且在粘性土壤的情况下,通过开挖土壤的断裂减小了碎屑的尺寸。 因此,作为泡沫的原料的表面活性剂容易吸附于土壤颗粒。 在步骤104中,将活性炭以破碎的泡沫进料到经处理的土壤中。 由于构成加工土壤的泥块尺寸明显减小,活性炭均匀地分散在沙土处理土壤甚至粘性土壤中。 因此,处理过的土壤中的表面活性剂被有效地吸附到活性炭上。 包括运输和装载在内的废土处理更容易进行。 版权所有(C)2013,JPO&INPIT
