传统船坞对于坞口 U 型贴面有着较为成熟的工艺,通常采用全花岗岩镶砌或者花岗岩镶砌与不锈钢板贴面相结合,作为船坞坞口止水的关键部位.在严寒地区,坞门止水橡胶条与坞口 U 型贴面之间可能发生冻结及撕裂,严重影响船坞的止水效果.船坞坞口不锈钢防冻热循环系统的应用,通过在不锈钢贴面板内侧设置热循环水管,辅助不锈钢贴面后方的钢结构箱体内空气隔热,有效的解决了严寒地区坞门止水橡胶条和不锈钢贴面冻结的难题.本文着重介绍一种适用于严寒地区的新型不锈钢防冻热循环系统的设计与施工技术,为今后类似项目提供参考经验.
Research on Design and Construction Technology of Anti-freezing Heat Cycle System Made of Stainless Steel at Dock Gate
An approved technology applies to U-shaped veneer of the traditional dock gate,which is usually made of all-granite inlay or the combination of granite inlay and stainless steel veneer,serves as the key water-stop part of the dock gate.In cold area,freezing and tearing phenomena may occur between water-stop rubber strip and U-shaped veneer of dock gate,which seriously affects water-stop effect.The application of stainless steel anti-freezing heat cycle system can solve effectively the trouble of freezing water-stop rubber strip with stainless steel veneer at dock gate in cold area by setting a thermal circulation water pipe inside stainless steel panel to insulating the air in steel structure box behind the stainless steel veneer.The design and construction technology of stainless steel anti-freezing heat cycle system will provide a reference for similar projects in cold area in future.
