一种资源节约型地下筒体构筑物的建造方法,涉及地下构筑物技术领域,所要解决的是降低施工成本、缩短工期、提高构筑物选址机动性及控制施工对周边环境影响的技术问题。该方法先用泥浆护壁法钻设中心孔,继而扩孔至设计孔径,然后将首个筒节的筒形钢模吊入孔内浮于泥浆液面上,并在钢模内绑扎钢筋、浇筑混凝土,完成首个筒节作业后筒节处于悬浮状态;从第二段高开始采用滑模浇筑筒壁,直至完成整个筒壁浇筑。完成第二段高的筒体总重力大于浮力的部分由孔口若干卷扬机的提吊力予以平衡;从完成第三段高筒壁浇筑起浮力大于筒体重力,卷扬机发挥稳定筒体之作用。本发明专利技术提供的方法,适用于各种特性的岩土层,适合城市建筑密集区的施工作业。

Method for constructing resource conserving underground cylinder structure

Method for building resource-saving underground tube structure, relates to the technical field of underground structures, which needs to be solved is to reduce the construction cost, shorten the construction period, improve the technical problems that influence the location flexibility and control of construction on the surrounding environment of architecture. This method first used mud drilling method with center hole, and then the design of reaming to aperture, and then the first cylindrical section of cylindrical steel mould hanging into the hole floating in the mud level, and in the steel mold steel banding, pouring concrete cylinder in suspension to complete the first cylinder after the operation; from the second section began using slipform tube wall, until the completion of the whole wall pouring. Complete the second section high tube total gravity is larger than the buoyancy part by opening several hoist by lifting force balance; from the completion of the tube wall pouring third paragraph of buoyancy is greater than the gravity of the tube body, a play a role of stabilizing the tube body. The method provided by the invention is suitable for the rock and soil layers of various characteristics and is suitable for the construction work in the urban construction concentrated area.
