FRP-steel composite pipe confined seawater and sea sand concrete column and preparation method thereof
The invention discloses an FRP-steel composite pipe confined seawater and sea sand concrete column and a preparation method thereof. The FRP-steel composite pipe restrained seawater and sea sand concrete column sequentially comprises an outer layer and an inner layer from outside to inside, a seawater and sea sand concrete filling layer is arranged between the outer layer and the inner layer, and an FRP reinforcement cage is arranged in the seawater and sea sand concrete filling layer; the outer layer sequentially comprises an FRP winding layer, a first steel pipe layer and a first FRP pultruded profile layer from outside to inside; and the inner layer sequentially comprises a second steel pipe layer and a second FRP pultruded profile layer from outside to inside. According to the FRP-steel composite pipe restrained seawater and sea sand concrete column, the FRP-steel composite pipe restrained seawater and sea sand concrete column of a special structure is constructed through the specific outer layer, the inner layer and the seawater and sea sand concrete filling layer, and the FRP-steel composite pipe restrained seawater and sea sand concrete column is high in pressure resistance and can be used for a long time in the ocean engineering environment.
本发明公开了一种FRP‑钢复合管约束海水海砂混凝土柱及其制备方法。该FRP‑钢复合管约束海水海砂混凝土柱，一种FRP‑钢复合管约束海水海砂混凝土柱，由外至内依次为外层和内层，所述外层与内层之间设有海水海砂混凝土填充层，且所述海水海砂混凝土填充层的内部设有FRP筋笼；所述外层由外至内依次为FRP缠绕层、第一钢管层和第一FRP挤拉型材层；所述内层由外至内依次为第二钢管层和第二FRP挤拉型材层。本发明通过特定的外层、内层以及海水海砂混凝土填充层构建了具有特殊结构的FRP‑钢复合管约束海水海砂混凝土柱，其抗压能力较强，可在海洋工程环境中长时间使用。
