Ultra-large annular concrete stainless steel water tank and manufacturing method thereof

Abstract

The invention discloses an ultra-large annular concrete stainless steel water tank and a manufacturing method thereof. The water tank comprises a concrete structure, a plurality of stainless steel water tank units and a plurality of communicating devices, wherein the plurality of stainless steel water tank units are embedded in the concrete structure through reinforcing ribs and anchor bars and are connected in series in sequence so as to form an annular structure, and each stainless steel water tank unit communicates with two adjacent stainless steel water tank units through communicating devices embedded in the concrete structure so as to jointly form an annular pool. According to the ultra-large annular concrete stainless steel water tank, the plurality of stainless steel water tank units and the communicating devices are embedded in the concrete structure and form a wheel-shaped integral concrete structure with inner and outer ring walls, and water pressure is transmitted to the concrete structure to bear by the stainless steel water tank units, so that the stability and the anti-seismic property of the whole structure are enhanced; and the stainless steel water tank units and the communicating devices can be integrally transported to a nuclear power site to be assembled after being prefabricated and formed in a factory, so that parallel manufacturing of the stainless steel water tank units in the factory and on-site modular construction are facilitated.

Description

technical field [0001] The invention belongs to the field of manufacturing super-large water tanks of nuclear power plants. More specifically, the invention relates to a super-large annular concrete stainless steel water tank and a manufacturing method thereof. Background technique [0002] Large pools for long-term storage of water in nuclear power plants are generally larger than 1000m 3 less than 2000m 3 , not only used to store coolants such as desalted water or boron-containing water, but also a barrier to prevent the leakage of radioactive substances. It has high sealing requirements and strong corrosion resistance. The overall structure requires shock resistance and a service life of up to 60 years. It should be flat and easy to decontaminate to avoid the accumulation of radioactive substances. [0003] Although the volume of conventional large-scale stainless steel fire-fighting water tanks can meet the requirements of large-scale pools in nuclear power plants, due...

AI Technical Summary

Problems solved by technology

In fact, for very large pools, especially those with a volume greater than 2000m 3 , and the structure is complex, and there is a closed pool with a curved surface. At present, there is no mature and feasible solution for domestic nuclear power plants.
