Prestressed hollow square pile reinforcing structure
The invention discloses a prestressed hollow square pile reinforcing structure, and relates to the technical field of prestressed hollow square piles, the prestressed hollow square pile reinforcing structure comprises a hollow square pile, a pile head protection assembly and a ground breaking assembly, the top of the hollow square pile is movably connected with the pile head protection assembly, and the bottom of the hollow square pile is fixedly connected with the ground breaking assembly; the portion, located on the surface of the ground breaking assembly, of the surface of the hollow square pile is fixedly connected with the ground, the surface of the pile head protection assembly is movably connected with the surface of the ground, and the hollow square pile comprises a pile body. The pile body is hammered to the ground through a pile driver, the vertical prestress reinforcing ribs are hammered to bear vertical loads and mainly bear the loads, concrete is poured into the pile body after hammering, the pile body is not prone to vibration due to the fact that the pile body is deep, when the concrete enters the pile body, the concrete falls on the arc-shaped plate on the uppermost layer, meanwhile, the spring is stretched through gravity, and vibration is prevented. The spring is prevented from falling off through the first drag hook and the second drag hook at the two ends, and at the moment, the arc-shaped plate bears the falling concrete.
本发明公开了一种预应力空心方桩加强结构，涉及预应力空心方桩技术领域，包括空心方桩、桩头防护组件和破土组件，所述空心方桩的顶部活动连接有桩头防护组件，所述空心方桩的底部固定连接有破土组件，所述空心方桩的表面且位于破土组件的表面固定连接有地面，所述桩头防护组件的表面与地面的表面活动连接，所述空心方桩包括桩体。本发明通过打桩机将桩体锤击地面，锤击使竖向预应力加强筋来承载竖向荷载以及主要承载，锤入后对桩体内部灌入混凝土，因桩体较深导致不容易振捣，在混凝土进入时，掉落在最上层的弧形板同时重力将弹簧进行拉伸，通过两端的拉钩一与拉钩二避免弹簧掉落，此时弧形板将掉落的混凝土承载。
