Description

Technical Field

[0001] The present application relates to the technical field of storage ring engineering construction, and in particular to a storage ring tunnel double-side wall construction system. Background Art

[0002] The storage ring tunnel is an important part of the high-energy synchrotron radiation light source project, which is used to store and accelerate electron beams to produce high-energy synchrotron radiation light. The storage ring tunnel usually has a high vacuum environment to ensure that the electron beam is not disturbed by the outside world during the acceleration process; at the same time, the tunnel is also equipped with a series of advanced magnets and control systems to accurately guide and stabilize the movement of the electron beam, which is widely used in research in many fields such as materials science, biomedicine, energy and environment.

[0003] There are concrete walls on both sides of the storage ring tunnel. The prior art discloses an arched tunnel structure and an arched tunnel construction method, which includes a plurality of support rods, a plurality of top supports, a plurality of arched beams, a plurality of lower ribs and a plurality of arcuate lower templates. The top supports are located at the ends of the support rods and supported by the support rods. A plurality of arched beams are arranged at intervals along the longitudinal direction of the tunnel, and each arched beam is supported by a plurality of top supports. Each lower rib extends along the longitudinal direction of the tunnel, and a plurality of lower ribs are arranged at intervals along the length track of the arched beam, and each lower rib is supported by at least two adjacent arched beams. A plurality of arcuate lower templates are supported by the lower ribs, and a plurality of arcuate lower templates are spliced ​​into an arched lower casting surface, and the lower casting surface is located on the side of the arcuate lower template facing away from the lower ribs. During casting, the force of the lower casting surface is dispersed to the length track lines of the plurality of lower ribs, and then to the length track lines of the plurality of arched beams, and then to each top support, and the length track line of the lower ribs is perpendicular to the length track line of the arched beam, so that the lower casting surface maintains an arch shape during casting.

[0004] Regarding the above-mentioned related technologies, since the radius of the storage ring is generally large, it is impossible to build the forming formwork as a whole and then cast it in one go, and it is necessary to adopt a segmented construction method. During the segmented construction, it is necessary to first build the forming formwork in one place and then pour concrete. After the concrete pouring is completed, the forming formwork needs to be disassembled and then hoisted to the adjacent construction site for re-building. This is repeated until the walls of the storage ring tunnel are all constructed. Since the walls on both sides are constructed in different time periods, the casting quality of the inner and outer walls will be inconsistent. Moreover, this construction method requires repeated disassembly and assembly of the forming formwork, and also requires the use of hoisting equipment, which not only affects the construction time, but also leads to a high cost for the use of the hoisting equipment used in the construction. Summary of the invention
