Centrifugal intelligent construction device for excavation concrete structure, and application thereof

Abstract

The present invention discloses a centrifugal intelligent construction device for excavating concrete structure: a push-type excavation equipment, excavating rocks and soil, and collecting crushed stones, sand, soil, and water; a centrifugal screening equipment, performing centrifugal screening and classification collection on the collected crushed stones, sand, soil, and water; the intelligent batching equipment, which matches the classified crushed stones, sand, soil, and water according to their quality and fineness, adding cementitious materials, auxiliary materials, additives, and activators, and mixing them to obtain a mixed wet material; a centrifugal printing equipment, pumping and extruding the mixed wet materials, and using a centrifugal rotating outer cylinder to print and compact them into dense shape; an intelligent reinforcement equipment, integrating reinforcements between the layers of printed concrete strips by using the wall mounted laying, positioning and inserting reinforcements inside the printed concrete strips during the centrifugal printing process to form an integrated reinforced concrete structure. The device can achieve the additive and intelligent construction of closed concrete structures in underground, underwater, and extreme construction environments, solving the technical dilemma of insufficient engineering application scope of open additive manufacturing technology.
