Technology for preventing seepage of suspended water cooling pond wall of corex furnace by means of reaming, pipe penetrating and blocking

Abstract

The invention discloses a technology for preventing seepage of a suspended water cooling pond wall of a corex furnace by means of reaming, pipe penetrating and blocking. The technology comprises the steps that firstly, an original pipe penetrating hole in the pond wall is reamed, and after reaming is finished, a pipe is sleeved with an inner flange piece in advance, the inner flange piece is closely attached to the pond wall, and then the inner ring of the inner flange piece and the outer wall of the pipe are fully welded; grouting at the initial stage is carried out, grouting and tamping are firstly carried out in a cavity formed by the pipe and the lower portion of the pond wall, the weight ratio of components, namely, high-strength quick-dry contraction-free cement mortar to small gravel to alkyd enamel to water, of grout during grouting at the initial stage is 4:1:1:8, outer flange pieces are used for blocking, then the pipe wall is beaten every other 20 min to 30 min to generate vibration, gaps are filled till the cavity is thoroughly full, and the outer flange pieces are covered with wool felt; and secondary smearing is carried out, after 3 days to 5 days, coating is smeared to the outer surfaces of the outer flange pieces, the weight ratio of components, namely, high-strength quick-dry contraction-free concrete mortar to washed-out sand to paint to water, of the coating is 4:1:1:4, and water can be injected for testing after standing is carried out for 2-3 days and impurities in a pond are cleared away.

Description

technical field [0001] The invention relates to the field of blast furnace slag production, in particular to a leak-proof process of reaming the wall of a suspended cold water pool of an Ouyeel furnace through a pipe for sealing. Background technique [0002] The water slag operation area of ​​Ouyeel Furnace has a water circulation system mainly composed of water pools, such as dry slag pit circulation pool, water collection pool, hot water pool, filtrate return pool, cold water pool, etc. The cold water pool is a pool with a concrete structure above the ground, and the bottom is an inverted cone structure . The overflow pipe of the cold water pool has been leaking through the wall of the pool, causing the ground in the granulation pump room to be wet and the environment is very poor. The current seepage water damages the surface of the pool wall. The diameter of the overflow pipe of the cold pool is DN100. When the water level of the pool reaches the overflow level, the ov...

Problems solved by technology

The overflow pipe of the cold water pool has been leaking through the wall of the pool, causing the ground in the granulation pump room to be wet and the environment is very poor

The current seepage water has caused damage to the surface of the pool wall. The diameter of the overflow pipe in the cold pool is DN100. When the water level of the pool reaches the overflow level, the overflow effect is not obvious, and the water level rises rapidly.
