End type prestress batter pile and construction method thereof
The invention relates to an end type prestress batter pile which comprises a surrounding purlin, a fender post, a batter pile body and a loading device. The surrounding purlin is supported by the fender post. The batter pile body is driven into soil before excavation, a set interval is reserved between the top end of the batter pile body and the surrounding purlin, the loading device is arranged in the set interval, and presetress is exerted to the batter pile body by the loading device through counter-force provided by the surrounding purlin. According to the end type prestress batter pile, the prestress device is exerted before excavation, and the bearing force of the batter pile body is fast developed; a prestress exerting device is additionally arranged on the existing batter pile body, reaction thrust can be provided for the batter pile body through force transmission equipment, and the batter pile body deforms; therefore the bearing force of the batter pile body is fast developed, foundation pit deformation is controlled, and the surroundings are protected; and a prestress adding device can be recycled.
本发明涉及一种端部式预应力斜桩，包括围檩、围护桩、斜桩、加载装置；所述围檩由围护桩支撑；所述斜桩在开挖之前打入土中，斜桩顶端与围檩之间预留一设定间距，所述设定间距内设置所述加载装置，所述加载装置通过围檩提供的反力对斜桩施加预应力。本发明开挖前施加预应力装置，快速发挥斜桩承载力；在既有斜桩上增设了预应力施加装置，可通过传力设备向斜桩提供反推力，让斜桩提前产生变形，从而快速发挥斜桩承载力，控制基坑变形并保护周边环境；预应力加力装置可回收。
