Simultaneous slip-form construction device of multi-limb high pier

Abstract

The invention belongs to the technical field of high pier slip-form construction, and particularly relates to a simultaneous slip-form construction device of a multi-limb thin-walled hollow high pier to solve the problems that when a traditional slip-form construction technology is used for construction of the multi-limb high pier, the construction cycle is long, cost is high, construction quality is low and the safety control difficulty is high. The simultaneous slip-form construction device comprises a slip-form portion, a lifting portion and a cargo transportation portion. The slip-form portion comprises panels of the multi-limb high pier and a truss, wherein the panels are connected into a whole through the truss which is of a symmetrical structure. The simultaneous slip-form construction device of the multi-limb high pier has the advantages that the defect that loads are uneven in the slip-form construction process is overcome; multiple construction working faces are formed and can alternately work, and therefore waiting time of concrete casting is shortened; the construction schedule is accelerated, meanwhile, investment for cranes or concrete pumps is reduced, and the construction cost is reduced; the influences of unfavorable weather on construction are reduced, and the construction quality and the continuity of slip-form construction are ensured; construction efficiency is improved, and the overall construction period is shortened by 50% or more.

Description

technical field [0001] The invention belongs to the technical field of sliding form construction of high piers, and in particular relates to a simultaneous sliding form construction device for multi-leg thin-walled hollow high piers. Background technique [0002] Slip form is a method of constructing high-rise concrete buildings. The known slip form device is composed of several formwork, support frame and jacking or lifting system. Sliding is generated and the concrete is continuously built as the formwork is lifted to achieve an increase in the height of the concrete structure. [0003] As expressway construction increasingly enters mountainous areas, many new and simpler pier structures are used in the construction field, and higher pier heights frequently appear. In the process of high pier construction, it is more and more difficult to arrange the construction site in the early stage, construction technology, cost control and performance of the construction period.
