Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] Such as figure 1 and figure 2 As shown, a kind of rigid platform for heavy impact load test of the present invention comprises steel plate 1, bolt 2, nut 3, supporting leg 4, concrete 5, screw 6; Wherein, steel plate 1 is made of steel plate module 11, steel plate The module 12 and the steel plate module 13 are spliced, and the splicing overlap between the adjacent steel plate module 11 and the steel plate module 12, and the splicing overlap between the steel plate module 12 and the steel plate module 13 are provided with several bolt holes 7. Positioning lap grooves are convenient for installation and positioning and ensure that the joints are flat; bolts 2 pass through bolt holes 7 on the positioning lap grooves and are screwed and fixed with nuts 3, and the adjacent steel plate modules 11 and 12, steel plate modules 12 and The stee...

The invention relates to a rigid platform for a heavy impact load test. The rigid platform solves the problem that a large-size and large-thickness rigid platform specially suitable for a drop test of a hundred-ton container is lacked at present. The platform steel plate provided by the invention is formed by positioning and overlapping a plurality of steel plate modules, and the steel plate modules are connected and fixed by bolts and nuts; a plurality of supporting legs are fixed at the bottom of the steel plate through welding or bolt and nut connection and are fixed on a foundation; concrete is poured between the steel plate and the foundation, a plurality of exhaust holes are formed in the steel plate and used for exhausting gas during concrete pouring, and gaps between the lower surface of the steel plate and the concrete are avoided; after concrete pouring is completed, screws and / or plugs are installed to plug the exhaust holes; and finally, all bolt holes and screw holes are sealed and welded, so that rainwater, dust and sundries are prevented from entering. By adopting the rigid platform provided by the invention, the drop test is carried out on the radioactive substance storage and transportation container, so that the safety and the effectiveness of the drop test of the hundred-ton container are ensured.
Description
technical field [0001] The invention belongs to the field of storage and transport containers for radioactive articles, and relates to a rigid platform for heavy impact load tests. Background technique [0002] According to the provisions of the national standard "GB 11806-2019 Regulations for the Safe Transport of Radioactive Materials", transport containers for radioactive materials need to undergo corresponding drop tests and meet the requirements before they can obtain design approval. The size and weight of the transport container for hundreds of tons of radioactive materials are relatively large, and the safety and effectiveness of the test can only be guaranteed if the drop test is performed on a drop test platform with a large size and thickness. [0003] At present, the existing drop test technology lacks a large-size, large-thickness rigid platform specially suitable for the drop test of a hundred-ton container, and it is impossible to perform a drop test on a hund...
