This paper analyses the function and characteristic of M. A. N gasholder and flexible seal gasholder in blast furnace gas storage.

Based on production practice experience for many years, the stoppage measures of leak point in cup of low-pressure water-sealed spirally-guided gasholder are discussed.

The paper compares the methods dealing with water leakage from trough bottom of water-sealed gasholder, and introduces the construction way and effect of excavation method.
