48 columns support the Ice World

Updated: 2017-07-14


The column construction of Xiangjiang Happy City Ice World project has finished and the main platform construction was fully launched.

As a theme park, Xiangjiang Happy City Ice World hangs over a deep pit of 100-meter high. Its main structure is mainly composed of vertical bracing, platform and roof, among which vertical bracing is composed of 48 concrete columns higher than 48 meters. It mainly provides the strength support for the entire building. On July 12, with the completion of the final concrete pouring, 48 columns have all been completed, marking the full start of the main platform construction.

Zhao Jinguo, project manager of the first department of Xiangjiang Happy City general contractor from Chinese Construction Fifth Engineering Bureau, told the reporter that the main part of the Ice World is a composite structure of giant steel with large span, high pit and heavy load, of which the vertical bracing is composed of 48 columns (including 3 batter columns), four A-type columns, a large gradient square columns and 18 shear walls. The heights of the vertical structures range from 48 to 57 meters. The minimum and maximum diameters of the cross sections are 1.2 and 4.3 meters respectively.

Zhao Jinguo introduced that the overall design of Ice World project makes full use of the specific terrain of the mining pit, which is a comprehensive development for the industrial sites, and also is the ecological restoration and use for the mining pit. No construction work across the country is as difficult as this because these columns are located in the bottom of the mining pit with a vertical drop of 100 meters due to the exploitation of stone. Some of the columns are also built directly above the surrounding rocks. Thus, the terrain and geological conditions are extremely complicated. In this regard, the project department fully utilized its strengths ,made comparison and selection for the construction program as well as the optimized the whole process. In addition, they also strengthen the construction quality and safety management during the raining season or the night, strictly checking on every construction process and continuously solving the problem encountered in the construction.

According to the design, after the completion of the Ice World project, a water park will built in the bottom of 16-meter platform, the depth of the water storage reaches 25 meters, covering one-third of the area of the mining pit, which creates a visual effect that the whole Ice World is floating on the surface of the water.
