Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail: the present invention is according to the roundness requirement that the upright annular structure designs, half ring is provided with horizontal stay cable to control the construction process of lower half ring in the opening installation state of ring structure and ensure that the installation process of the upper half ring does not cause the deformation of the lower half ring to deviate from the design position and outward; when the ring structure is installed and constructed to the upper half ring, install the mast and the stay cable to adjust The deformation of the upper half ring during the installation process ensures the roundness requirements after the structure is formed; before the ring is closed, the deformation and force of the entire ring are adjusted by the cantilever ends on both sides of the opening and closing opening through the jack, so t...

Abstract

The invention provides a cantilever mounting method for a large-diameter upright annular structure in an open state in a civil engineering construction, in particular a deformation control method for combination of opening a closed opening by a jack and embedding a closed section in a mounting process from opening to closing the opening by using a horizontal inhaul cable, a mast and a stay cable.In the invention, according to characteristics of the large-diameter upright annular structure and the rigidity of an actual structure, the horizontal inhaul cable is arranged in a middle area to control deformation during mounting a lower half ring of the annular structure; the mast and the stay cable are mounted on an external side edge to control deformation during mounting an upper half ring;and the deformation of the whole circular ring is adjusted through a jacking structure of the jack and the closed section is embedded before the circular ring is closed; therefore, forming roundness of the annular structure can be effectively assured. In the construction, a large quantity of bearing jigs are saved, the construction measure cost is reduced, and the stability of an open upright annular structure is increased by using a temporary assistant structure and the tension of a pretightening force of the inhaul cable to effectively assure the construction safety in the mounting process.

Description

technical field [0001] The invention relates to a method for cantilever installation of a large-diameter upright ring structure in an open state in civil engineering construction. The invention relates to a deformation control method combining a cable-stayed buckle cable and a jack opening and closing opening embedded in a closing section, belonging to the technical field of construction and installation of ring-shaped special structures. Background technique [0002] The vertical ring structure is a new type of special structural system, which consists of a fixed base part embedded in the foundation and an upper vertical ring structure part, usually used as a component of landscape architecture, or urban sculpture, or a new type of entertainment and sightseeing Ferris wheel structure type. The well-known large-diameter upright ring structure at home and abroad can be installed in the following ways: (1) The ring structure is assembled and formed lying on the ground, and th...
