The next stage of construction of a stormwater storage tank has been completed at the Polymetals Plant

Kirovgrad (Sverdlovsk region)

The branch "Production of polymetals " (PPM) of JSC "Uralelectromed " (an enterprise of the metallurgical complex of UMMC) is implementing the "Program for organizing a system for the collection and treatment of industrial and storm water branch PPM ", calculated until 2024. The construction of the stormwater storage facility 5.1 is one of the most significant stages. In November, one of the major elements was completed - the reinforced concrete bottom of the stormwater storage tank was completed.

- The bottom is on 77 bored reinforced concrete piles, 600 mm in diameter. All of them perform the function of anchors, preventing the stormwater storage tank from being squeezed out of the ground by groundwater. In the course of the work, they encountered the peculiarities of the soil: in some places they had to drill holes in the rocky soil, which significantly complicated the work. However, this increased the strength characteristics of the future structure, - said the head of the capital construction department of the PPM Evgeny Lavrov.

After the installation of piles and concrete preparation, a four-layer waterproofing with bitumen mastic was performed. As a result, the total thickness of the waterproofing layer was approximately 6 mm. For concrete preparation with waterproofing, in a continuous mode for two days, an 800-mm layer of special sulfate-resistant concrete in the amount of 530 cubic meters was laid.

Currently, work is underway to construct a reinforced frame for the walls of the rainwater storage tank. Modern additions to concrete and additional electric heating will allow not to interrupt construction work in winter.

The concrete work was preceded by earthworks. Let us remind you that the first stage was the preparation of the pit, the depth of which was about eight meters.

The rainwater storage tank will be the first of six structures of the branch's closed water circulation system. It will collect and accumulate storm water from the entire industrial site of the branch. The effluent will then be pumped to the existing neutralization station, where it will be treated.
