Description

In the present invention, in the underground of a structure or the like, in order to delay the discharge of groundwater or the like, the efro adhering to the inside of the pipe such as a vertical pipe is gradually dissolved and removed to discharge the stagnant groundwater or the like. Regarding the removal and sticking prevention method.

Conventionally, for example, in the underground of a structure, calcium hydroxide in the mortar dissolves in rainwater or groundwater that has entered and exudes from cracks or joints, and reacts with carbon dioxide in the air to form calcium carbonate. Efro slaked (hereinafter referred to as efro) adheres to the inside of a pipe such as a vertical pipe that promotes the discharge of groundwater, etc., thereby removing the efro in the pipe such as a vertical pipe in a state where the discharged water such as groundwater is stagnant. As a method for doing so, it is generally known to clean the inside of a pipe using an ultra-high pressure washing machine or remove it using a pipe tool.

However, when the efro is removed by cleaning the inside of the pipe using the former ultra-high pressure washer, not only the cost of the cleaning work is extremely high, but also the wastewater from the cleaning is treated as industrial waste, so that the treatment is extremely complicated. Yes, the cost will increase here as well. Furthermore, if the latter tube tool is used to remove the efro in the tube, not only may the tube be damaged through the tube tool, but if it is damaged, a large amount of pipe replacement work may be required. Therefore, not only is it a high risk, but there is also the possibility of recurrence of Efro, and depending on the state of Efro sticking, there have been a number of problems that it cannot be easily penetrated even with a tube tool. ..

Furthermore, when the efro is removed by using the former and the latter means, the stagnant discharged water such as groundwater may be discharged at once due to the momentary removal or penetration of the efro, and therefore, in rare cases. However, there was also a problem that the branch joint portion was damaged by the water pressure when the discharged water suddenly rushed to the branch joint portion below the vertical pipe.
