    • PROBLEM TO BE SOLVED: To efficiently break foams of excavated soil produced in rheological foam shield tunneling work, without imposing a load on an environment.SOLUTION: In a method for treating excavated soil in rheological foam shield tunneling work, firstly, the excavated soil is discharged from a chamber 6 of a shield machine 5 via a screw conveyor 1 connected to the chamber in the state of communicating with it (step 101), and subsequently sent into a line mixer 2 that is disposed on the discharge side of the screw conveyor. After that, a water absorbing material charged into the line mixer 2 is added to the excavated soil to turn it into treatment object soil (step 102), and the treatment object soil is agitated and mixed by the line mixer 2 to uniformly disperse the water absorbing material in the treatment object soil (step 103). Next, the soil after the completion of water absorbing treatment is carried out to the rear of the shield machine 5 by a belt conveyor 4 that is displaced on the downstream side of the line mixer 2 (step 104).
    • 要解决的问题:有效地破坏在流变泡沫屏蔽隧道工作中产生的挖掘土壤的泡沫,而不会对环境造成负担。 解决方案:在流变泡沫屏蔽隧道工程中处理挖掘土的一种方法中,首先,挖掘的土壤通过连接到室的螺旋输送机1从屏蔽机5的室6排出,处于与 (步骤101),并随后送入配置在螺旋输送机排出侧的管线混合器2。 之后,将加入到线混合器2中的吸水材料添加到挖掘的土壤中,将其转化为处理对象土壤(步骤102),并且通过管线混合器2将处理对象土壤搅拌混合以均匀地分散水 在处理对象土壤中吸收材料(步骤103)。 接下来,通过在线路混合器2的下游侧移位的带式输送机4,在屏蔽机5的后方进行吸水处理完成后的土壤(步骤104)。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an excavated soil disposal method for preventing viscous soil contained in excavated soil from dissolving into water. SOLUTION: According to the excavated soil disposal method, processing water obtained by adding a nonionic thickening agent to water is fed into a chamber 5, according to excavation of a slurry-type shield machine 1. The excavated soil generated by the excavation of the slurry-type shield machine 1 is mixed with the processing water in the chamber 5 by an agitator 8, but by virtue of aggregation effect of the nonionic thickening agent contained in the processing water, the viscous soil contained in the excavated soil does not dissolve into the water. The processing water is adjusted so as to have a specific gravity and a specific viscosity of about 1.00 to about 1.25, and about 20 to about 40 sec, respectively, for instance.
