Reusable reinforced concrete composite pile available for on-load segmental disassembly and construction method of reusable reinforced concrete composite pile available for on-load segmental disassembly

Abstract

Disclosed are a reusable reinforced concrete composite pile available for on-load segmental disassembly and a construction method of the reusable reinforced concrete composite pile available for on-load segmental disassembly. The reusable reinforced concrete composite pile comprises a lower reinforced concrete pile body and an upper steel box structured pile body. The upper steel box structured pile body is composed of unit steel boxes. Segmental alternate stressing of a bearing face of the top unit steel box is realized by the aid of two jack sets, so that the pile body can be segmentally disassembled under the continuous on-load stressed condition, and variability of top load stress elevation is realized. The upper steel box combined pile body is connected through bolts under protection, so that disassembly and reuse of steel box units are facilitated.

Description

Technical field [0001] The invention relates to the field of construction of building structures. In particular, it is a composite pile body structure for providing vertical bearing capacity. Under the condition of continuous loading and stress, the composite pile can be divided into blocks and alternately loaded, disassembled in sections, and can be reused, which is beneficial to low carbon and environmental protection. . Background technique [0002] During the construction of foundation pits, temporary piles are used to provide vertical bearing capacity on the large-load operating platforms necessary for some projects, which need to be completed before the excavation of the earth, and the elevation should be adjusted with the excavation of the earth, and then demolished after completion. Based on the existing construction method, it can only be set repeatedly, which leads to increased costs and longer construction period; the current existing construction method uses temporar...

Problems solved by technology

Based on the existing construction method, it can only be set repeatedly, which leads to an increase in cost and a long construction period; the upper steel structure of the temporary steel-concrete composite pile used in the existing construction method mostly adopts integrally welded steel pipes or Steel lattice columns are all one-time investment, even if they are only treated as waste materials after recycling, they cannot be reused, which is not conducive to low-carbon environmental protection
