Problems solved by technology

Due to the different degrees of damage to the soil above the base level during the dismantling of the original foundation, the newly configured platform and equipment foundation can only be placed in the old soil layer, and cannot make full use of the original foundation and the old soil layer above the level. Soil, this approach will not only prolong the project period, but also increase the project investment

Embodiment Construction

[0009] Embodiment of the present invention: the large-scale prebaked electrolytic cells are arranged in a single row along the factory building instead of the original double row, and the azimuth is rotated by 90 degrees. Such as figure 1 As shown, cut off the foundation small column and platform column (1) of the original self-baked electrolytic cell within the foundation range of the large pre-baked electrolytic cell to 300mm below the ground level, and use gravel or soil intercalated rocks as a cushion (2) to the ground Plane, the large prebaked electrolytic cell foundation (3) is made into a whole-slab foundation, the base is placed on the ground plane of the cushion layer (2), and the load on the bottom surface of the large prebaked electrolytic cell foundation is controlled to be ≤ 100Kpa.

Abstract

The foundation construction process of reforming self-roasting electrolytic bath into large pre-roasting electrolytic bath includes cutting the foundation column and platform column of the original self-roasting electrolytic bath to below the ground level and forming bedding with broken stone or horsestone to ground level; and forming integral foundation of large pre-roasting electrolytic bath set on the ground level. The present invention can save engineering investment greatly and shorten the engineering duration by means of utilizing the old foundation with stable foundation deposition, and raised bearing capacity and compactness of soil.

Description

Technical field: [0001] The invention relates to a foundation construction method for an aluminum electrolytic cell. technical background: [0002] The self-baking electrolysis plant is generally a single-story building with a span of 21 meters or 24 meters, with a column spacing of 6000mm and an operating platform elevation of 2.500m. The double-row electrolytic tanks are arranged symmetrically along the longitudinal direction, with a tank spacing of 8760mm, and each tank has 8 concrete piers. The self-baking electrolysis process is backward and the pollution is serious. In order to solve this pollution problem, new factories have adopted more advanced pre-baking electrolysis process since the 1980s. For the old factory, the process transformation from self-baking electrolyzer to pre-baked electrolyzer has greatly changed the platform and equipment infrastructure in the factory. The previous practice is: first remove the original platform and foundation, and then construct...
