The invention relates to a method for treating gas leakage defect of cement-based pier of blast furnace. Through high-pressure grouting at the furnace base, the main passageway for gas leakage downward from the bottom sealing plate of blast furnace is blocked, and a large amount of gas leakage from the bottom sealing plate defect to the furnace base and cement base is prevented, so as to ensure the safe construction of cement-based pier in on-line construction process, and at the same time, the furnace base is protected. The metal sealing structure is made at the joint of the periphery sealing plate and the cement base, and a small amount of pressure gas is discharged out of the cement base pier from the outside of the furnace. The metal enclosure is made to seal the cement-based part as a whole, and the sealing filler is added to the metal enclosure. At the same time, the sealing structure is made at the bottom of the metal enclosure of the cement-based enclosure and the joint of the cement foundation. The sealing construction is carried out by using a variety of sealing materials such as polymer sealant. Ensure that the cement-based leaking gas is sealed in the steel plate sealing structure, and it will no longer leak out from the joint of metal structure and cement foundation, thus preventing the gas leaking from the cement-based pier of blast furnace.
