Forming method of self-protective wall large-diameter concrete hollow tubular pile foundation
The invention discloses a forming method of a self-protective wall large-diameter concrete hollow tubular pile foundation. The self-protective wall large-diameter concrete hollow tubular pile foundation comprises an annular dense net reinforcement cage skeleton and an underwater annular protective wall. The annular dense net reinforcement cage skeleton is formed by binding inner and outer longitudinal main reinforcing bars, inner and outer annular stirrups, inner and outer annular stiffening bars, radial bars, inner and outer locating bars and inner and outer annular dense nets in a factory oron site. The underwater annular protective wall is formed by pouring underwater non-separable self-compaction fast setting concrete into the space between the outer annular dense net and the hole walls of drilled holes. During the pouring process of a pile body of the tubular pile foundation, external large formworks are not needed; pouring forming of the pile body can be completed just through the structure and a lightweight inner membrane of the tubular pile foundation. The problems that large formworks are hard to manufacture, hoist, recover and the like are solved. Site construction is faster and more efficient. The construction cost is greatly reduced.
本发明公开了一种自护壁大直径混凝土空心管柱基础成型工法，包括环形密致网钢筋笼骨架和水下环形护壁，环形密致网钢筋笼骨架由内外层纵向主筋、内外层环向箍筋、内外层环向加劲筋、径向筋、内外层定位筋和内外层环形密制网在工厂或现场绑扎制作；水下环形护壁由水下不分离自密实速凝混凝土浇筑在外层环形密制网与钻孔孔壁之间的间隙中形成。管桩基础桩身浇筑中无需外用大型模板，仅依靠自身结构和轻型内膜即可完成桩身浇筑成型，解决了大型模板制作、吊放和回收等难题，使得现场施工更加快捷高效，大大降低了工程造价。
