Example Embodiment

[0026] The following describes the present invention in further detail with reference to the accompanying drawings and embodiments, but it is not intended as any limitation to the present invention.

[0027] Examples. A waterproof method for large area concrete roof silos, such as figure 1 Shown. The method is constructed according to the following steps:

[0028] ① After the concrete on the roof of the concrete silo is initially set, remove the pouring formwork and rinse it with clean water;

[0029] ②. Use cement mortar to level the roof of the concrete silo. The thickness of the leveling layer is 20-25mm; the cement mortar is: ordinary Portland cement above 325 and clean medium sand with a particle size of 2.0~3.0 according to 1.2~1 : Mix evenly at the ratio of 2.5; mix with water according to the water-cement ratio 0.45-0.55 to form cement mortar.

[0030] ③ After the initial setting of the leveling layer, apply a layer of base treatment agent on the leveling layer; the ba...

Abstract

The invention discloses a waterproof method and a structure of a large-area concrete roof silo. The concrete roof silo is provided with two waterproof layers, the first layer is composed of a fine aggregate concrete waterproof layer of the top face, and the second layer is made of a macromolecule coiled material. The waterproof capacity of the silo is improved through two waterproof layers. Cracks of a large-area concrete roof are prevented, water leakage possibility is prevented, and normal electrolytic aluminum production is ensured well.

Description

technical field [0001] The invention relates to a waterproof method and structure of a large-area concrete roof silo, belonging to the technical field of roof waterproofing. Background technique [0002] Aluminum electrolysis is a metal smelting process. The main raw material is alumina powder to produce aluminum solution. When the alumina powder is transported through the alumina into the electrolytic cell for electrolysis, it is usually stored in the alumina powder storage bin, and the top area of ​​the storage bin is relatively large. , with a diameter of about 18 meters, if the purity of the aluminum ingots obtained by electrolysis after the alumina powder is soaked by unclean rainwater, it will be difficult to meet the process requirements and become a substandard product, so the roof waterproofing treatment of the silo is particularly important . And existing storehouse roof waterproofing is all one waterproofing, is three grades of waterproofing, and its waterproofin...
