Problems solved by technology
The stainless steel cladding structure is to wrap a layer of stainless steel on the surface of the concrete and carbon steel components. The problems of this method are that the construction is difficult, the construction period is long, and the steel cladding needs back ribs, which takes up a lot of space
[0004] In industrial projects, steel-concrete composite structures are often used, which have the advantages of high bearing capacity and good rigidity, but the steel used is carbon steel, which cannot meet the special requirements of nuclear chemical industry

Embodiment Construction
[0018] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.
[0019] An exemplary stainless steel-concrete composite structure used to replace stainless steel cladding structures in nuclear chemical industry such as figure 1 As shown, it includes a stainless steel pipe 1 and cast-in-situ concrete 2 poured therein. The cross section of the stainless steel pipe 1 is circular.
[0020] Another exemplary stainless steel-concrete composite structure used to replace the stainless steel cladding structure in nuclear chemical industry such as figure 2 As shown, it includes a stainless steel pipe 1 , cast-in-place concrete 2 poured in the stainless steel pipe 1 and steel bars 3 set in the cast-in-place concrete 2 . The cross section of the stainless steel pipe 1 is square.
[0021] figure 1 and figure 2 The stainless steel-concrete composite structure is mainly used in the beams and columns in...

The invention belongs to the technical field of nuclear chemical engineering, and relates to a use for a stainless steel-concrete composite structure replacing a stainless steel cladding structure innuclear chemical engineering. According to the stainless steel-concrete composite structure, concrete is poured in a steel frame. After the stainless steel cladding structure in the nuclear chemical engineering is replaced by the stainless steel-concrete composite structure, on the basis of guaranteeing the reduction effect of radioactivity, the construction is simple, the construction period is short, and the space occupied by the structure is small.
Description
technical field [0001] The invention belongs to the technical field of nuclear chemical industry and relates to the use of a stainless steel-concrete composite structure to replace the stainless steel cladding structure in nuclear chemical industry. Background technique [0002] In nuclear chemical projects, due to process requirements, the general equipment room, hot room and process pipe trench are equipped with stainless acid-resistant steel metal cladding, referred to as stainless steel cladding. This is because if radioactive objects directly contact materials such as concrete and carbon steel, the radioactivity is easy to penetrate into these materials, and it is impossible to wash and decontaminate them, so it is difficult to reduce their radioactivity. that can be reduced to an acceptable level. [0003] However, many rooms such as general equipment rooms, hot rooms and process pipe trenches involve complex processes. In order to meet the requirements of the process...
