Embodiment Construction

[0022] In order to further understand the present invention, the preferred embodiments of the present invention are described below in conjunction with examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the present invention, rather than limiting the claims of the present invention.

[0023] The invention provides a method for plugging leakage at the root of a storage tank, comprising the following steps:

[0024] 1) According to the location of the leakage of the on-site storage tank, the surface of the leakage point should be cleaned first, and the level of rust removal treatment should be ST3;

[0025] 2) Use iron cement as a primer to block the leakage point. After the iron cement solidifies, apply elastic liquid rubber on the outer surface of the cured iron cement and the outer wall surface of the adjacent storage tank, and wait until the elastic liquid rubber solidifies to form an elastic After the ...

Abstract

The invention discloses a leakage stoppage method for root leakage of a storage tank. Firstly, iron cement is used for bottoming and leakage stoppage, and then a steel plate is used for welding and reinforcing so that a double-leakage-stoppage effect with the iron cement inside and the reinforcing steel plate outside can be formed; at least one sealing layer is laid around the peripheral root of the storage tank through glass fiber cloth dipped with asphalt paint; and furthermore, an annular table with a slope face is manufactured on the outer surface of each sealing layer through grouting materials. According to the method, a multi-leakage-stoppage system is formed, leakage points are effectively plugged, then sealing corrosion prevention is performed on the basis of leakage stoppage, it is avoided that the leakage stoppage device loses efficacy in the subsequent using process, the using effect of the leakage stoppage device is improved, and the service life of the leakage stoppage device is prolonged.

Description

technical field [0001] The invention relates to the technical field of equipment anticorrosion, in particular to a plugging method for leakage at the root of a storage tank. Background technique [0002] Storage tanks are important static equipment in chemical production. The storage tanks on the production site are prone to leakage at the root of the storage tanks due to various factors such as corrosion aging and rain erosion. The leakage of the storage tank leads to the leakage of the storage liquid, destroys the on-site environment, and poses a great threat to personal safety. The leakage of the storage tank is generally concentrated at the root of the storage tank. The main reason is that the chemical corrosion intensifies at the root of the storage tank due to the accumulation of liquid at the root of the storage tank after the rain and the overflow of the storage liquid. When the storage tank leaks, there is generally a certain level of liquid stored in the storage t...
