    • PROBLEM TO BE SOLVED: To make an insolubilizing material permeate into a contaminated area in the ground while maintaining an insolubilizing effect.SOLUTION: In a method of insolubilizing harmful substances, first, the insolubilizing material, such as an iron oxide, is added to water together with a dispersant to be suspended, thereby preparing insolubilizing material slurry. A substance consisting of a polyacrylate, a polymethacrylate, or their copolymer and having a weight average molecular weight Mw of 10,000 to 14,000 is used as the dispersant. Next, as shown in Figure 1, the prepared insolubilizing material slurry is injected into the ground 1 through an injection well 3 to be permeated into the contaminated area 2 in the ground 1. In such a way, the insolubilizing material suspended uniformly in the slurry by the dispersant flows outside the injection well without clogging a strainer of the injection well 3, and reaches the contaminated area 2 while being entrained by a ground water flow without causing coagulating sedimentation in a space between soil particles of the ground 1 to permeate into the contaminated area, thereby insolubilizing harmful substances.
    • 要解决的问题:使不溶解材料渗入地下的污染区域,同时保持不溶解的作用。 解决方案:在使有害物质不溶解的方法中,首先,将不溶解材料(例如氧化铁)与待悬浮的分散剂一起加入到水中,由此制备不溶物料浆料。 作为分散剂,使用由聚丙烯酸酯,聚甲基丙烯酸酯或其共聚物构成的重均分子量Mw为10,000〜14,000的物质。 接下来,如图1所示,将制备好的不溶化材料浆料通过注射井3注入到研磨器1中,以便渗透到地面1中的污染区域2.以这种方式,将不溶性材料均匀地悬浮在浆料中 通过分散剂流入注射井外部,而不堵塞注射井3的过滤器,并在被地下水流夹带的同时到达污染区域2,而不会在地面1的土壤颗粒之间的空间中凝结沉淀,渗透到 污染区域,从而不溶解有害物质。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an agitation method of ground capable of reducing agitation torque when agitating contaminated ground with an agitation device, and to provide a cleaning method of ground capable of cleaning ground while agitating the ground. SOLUTION: The agitation device 1 comprises a rod 2, an agitation vane 3 attached to the tip part of the rod 2 and a base machine 4 for rotating the rod 2 and the agitation vane 3. A feed path 8 for feeding a nutrient which is a fluid and has lubricity into ground from the agitation vane 3 is disposed on the agitation vane 3, whereby the nutrient can be supplied into the ground. By supplying the nutrient into the ground, the nutrient exists around the agitation vane 3 and, therefore, frictional resistance between the agitation vane 3 and the ground can be reduced. Accordingly, the agitation torque for rotating the agitation vane 3 is reduced. COPYRIGHT: (C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To reduce an embedded depth of an earth retaining wall, by preventing settlement and drying-up of a well of the surrounding ground by excessive pumping of underground water.
      SOLUTION: In this ground excavation method, first of all, an air injection well 2 is arranged in the ground 3 so as to surround an excavation expected area 1, and the earth retaining wall 10 is built up along a boundary of the excavation expected area 1 (Step 101). Next, the boundary ground 6 sandwiched between the lower ground 4 positioned under the excavation expected area 1 and the surrounding ground 5 adjacent to the side of the lower ground, is changed to the unsaturated ground from the saturated ground by injecting air into the ground 3 via the air injection well 2, and water permeability of the boundary ground 6 is reduced (Step 102). Next, while pumping the underground water from a pumping well 9 arranged in the excavation expected area 1 in such a state, and while supporting earth pressure by the earth retaining wall 10, the excavation expected area 1 is excavated (Step 103).
