Proton waste beam station construction technique

Abstract

The invention relates to the field of buildings, in particular to a proton waste beam station construction technique. The proton waste beam station construction technique is characterized by comprising the following steps of a. externally coating a waterproof steel plate under a mounting bottom plate; b. casting a concrete bottom plate of a shielding iron box; c. mounting the shielding iron box; d. mounting a side wall steel formwork; e. casting side wall concrete; f. mounting a prefabricated concrete cover plate; g. casting top plate concrete; h. externally coating a waterproof steel plate; i. externally coating a reinforced concrete structure; j. externally coating a waterproof coil; k. arranging a waterproof protecting layer. The proton waste beam station construction technique has the advantages that the surface is dry and is free from wet stains; by utilizing multiple types and multiple layers of comprehensive waterproof materials, the defect of use of single material is overcome, and the permanent waterproof function is realized; the requirements of shielding the radiation and resisting the scattering and pollution to surrounding water and soil environments are effectively met; the radiation and expanding of the single concrete structure after possible cracks can be avoided; by firstly mounting the shielding iron box and then externally coating the side wall, the influence on the gap accuracy caused by the manufacturing error of the iron box is avoided; the anti-deformation capability of the formwork is improved by a steel truss, the root part is welded and positioned, a temporary stopper is arranged at the upper part, and the gap accuracy is guaranteed.

Description

technical field [0001] The invention relates to the field of construction, and more specifically relates to a construction technology of a proton waste beam station. Background technique [0002] Compared with X-ray technology and synchrotron radiation technology, neutron scattering technology has many advantages in material science and life science research. However, due to the high radiation of neutrons, its use will cause serious radiation pollution to the environment. In order to avoid radiation pollution, it is necessary to build a proton waste beam station that can avoid radiation pollution to process neutron waste beams. The building construction technology in the existing technology cannot realize the surface of the proton waste beam station to be dry and free of wet stains, and the defect of using a single material cannot realize the permanent waterproof function, let alone effectively realize the needs of shielding radiation and resisting scattering to pollute the ...

However, due to the high radiation of neutrons, its use will cause serious radiation pollution to the environment. In order to avoid radiation pollution, it is necessary to build a proton waste beam station that can avoid radiation pollution to process neutron waste beams. The building construction technology in the existing technology cannot realize the surface of the proton waste beam station to be dry and free of wet stains, and the defect of using a single material cannot realize the permanent waterproof function, let alone effectively realize the needs of shielding radiation and resisting scattering to pollute the surrounding water and soil environment; In addition, if a single steel plate is used to shield radiation, a thicker steel plate is required, resulting in high cost, and cracks in the single-layer concrete structure are likely to cause radiation to expand; finally, the existing technology cannot avoid the formwork during the construction process. Deformation affects the accuracy of the gap between the shielding iron box and the steel plate
