Suspending and guiding device for descending installation of large-scale steel jacket box

Abstract

The invention relates to the field of descending installation construction of a steel jacket box, in particular to a suspending and guiding device for descending installation of a large-scale steel jacket box. The suspending and guiding device is provided with a suspending device and a guiding device, wherein the suspending device is provided with a continuous jack; suspending steel strands are connected to the continuous jack; bearing beams are arranged at the bottom of the continuous jack; the guiding device comprises a pile foundation steel casing below the bearing beam; a concentric adherent arc-shaped plate is arranged on the left side of the pile foundation steel casing; a concentric interval is formed between the pile foundation steel casing and the concentric adherent arc-shaped plate; the left side of the concentric adherent arc-shaped plate is connected with a baseplate and a top plate which are clung to the inner wall of the steel jacket box; the lower part of the baseplate is connected with an anchor bearing plate; connecting plates arranged on the baseplate are arranged above the anchor bearing plate; and webs are further arranged between the concentric adherent arc-shaped plate and the inner wall of the steel jacket box. The suspending and guiding device has the beneficial effects of simple structure, convenient blanking, high raw material utilization ratio, green and environment-friendly construction and low construction difficulty, and the suspending and guiding device is processed and mounted together with the steel jacket box, so that the construction efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of lowered installation and construction of steel casings, in particular to a suspension device and guiding device for the lowered installation of large steel casings. Background technique: [0002] With the widespread construction of highways, railways, municipal bridges and other bridge projects in my country, the positioning and lowering of large steel casings have become key technical control points for cross-sea and cross-river projects. In order to ensure the accurate positioning and lowering installation of the steel casing, it is necessary to set lowering suspension devices and guiding devices in all directions of the casing. The main suspension device and guide device of the traditional large-scale steel casing are installed separately, so there is more waste of steel, the construction workload is large, the construction convenience is poor, and the construction progress is slow. [0003] Therefore, it is n...
