The invention provides a prestressed high-strength concrete hollow support pile. The prestressed high-strength concrete hollow support pile comprises a reinforcement cage framework and a concrete pile body, the cross section of the concrete pile body is in a polygonal hollow tube shape, and the concrete pile body comprises a pile body upper flange plate, a pile body lower flange plate, a pile body left side supporting leg, a pile body right side supporting leg, a pile body tenon and a pile body mortise groove. The pile body upper flange plate and the pile body lower flange plate are symmetrically arranged and are both formed by welding more than two longitudinal prestressed main reinforcements and more than two hoop reinforcements in a crossed manner; the hoop reinforcements are uniformly distributed between the pile body upper flange plate and the pile body lower flange plate in a surrounding manner; the pile body tenon and the pile body mortise groove are located on one side of the pile body left supporting leg and one side of the pile body right supporting leg correspondingly, and the pile body tenon and the pile body mortise groove are meshed and matched. Grouting reserved hole grooves are symmetrically formed between the pile body tenon and the pile body mortise groove. According to the prestressed high-strength concrete hollow support pile, the structure is stable, the soil fixing and water stopping effects are good, construction is easy and convenient, the construction cost is low, mechanical and automatic production machining procedures are adopted, the construction period is short, and the efficiency is high.
本发明提供一种预应力高强混凝土空心支护桩，包括钢筋笼骨架与混凝土桩身；其横截面呈多边形中空管状，包括桩身上翼缘板、桩身下翼缘板、桩身左侧支腿、桩身右侧支腿、桩身榫头和桩身卯槽；桩身上翼缘板与桩身下翼缘板对称设置，均采用2根以上纵向预应力主筋与2根以上环箍筋交叉焊接而成；桩身上翼缘板与桩身下翼缘板之间环抱均布环箍筋；桩身榫头和桩身卯槽分别位于桩身左侧支腿一侧和桩身右侧支腿一侧，且桩身榫头和桩身卯槽啮合适配；桩身榫头和桩身卯槽中间对称设有注浆预留孔槽。本发明结构稳固、固土止水效果好、施工简便、工程造价低，采用机械化、自动化生产加工程序、施工工期短、效率高。
