摘要： PROBLEM TO BE SOLVED: To provide a method for inhibiting the precipitation of an efflorescence with a leakage of water without using water stops.
SOLUTION: An injection hole 11 for injecting a carbon dioxide gas is drilled to the upper floor slab 10 of an underground structure K, and the carbon dioxide gas is injected to groundwater Wl from the injection hole 11 by using a carbon-dioxide gas injection device 30. Since the carbon dioxide gas is easy to dissolve in water, groundwater W1 is changed into carbonated water W1'. Since carbonated water W1' permeates to a crack 20 ( a water leaking section) in the upper floor slab 10 and calcium carbonate (a water insoluble substance) is precipitated on the internal side face of the crack 20, calcium ions do not reach to an opening section 20a on the surface side of the crack 20. The crack 20 is closed gradually by precipitated calcium carbonate. Accordingly, the precipitation of the efflorescence with the leakage of water can be inhibited.

摘要翻译：要解决的问题：提供一种用于在不使用止水剂的情况下用水泄漏来抑制风化沉淀的方法。解决方案：将用于注入二氧化碳气体的注入孔11钻入地下结构K的上层板坯10，并且二氧化碳气体通过使用二氧化碳从注入孔11注入地下水W1 气体注入装置30.由于二氧化碳气体容易溶于水，所以地下水W1变成碳酸水W1'。由于碳酸水W1'渗透到上层板坯10中的裂缝20（漏水部），并且碳酸钙（水不溶性物质）在裂缝20的内侧面析出，因此钙离子不会达到开口部20a在裂纹20的表面侧。裂纹20由沉淀碳酸钙逐渐闭合。因此，可以抑制风化与水的泄漏的沉淀。版权所有（C）2005，JPO＆NCIPI
