Reinforced concrete precast pile forming system and construction method
The invention provides a reinforced concrete precast pile forming system and a construction method. The reinforced concrete precast pile forming system comprises a pile driving hammer, a power head and a reinforced concrete pile. The pile driving hammer is arranged at the upper end of a pile driver to form a vertical piling mechanism. The pile driving hammer can be in contact with the upper end ofthe reinforced concrete pile. The power head is arranged on a piling platform and is located below the vertical piling mechanism. A lifting cylinder is arranged between the power head and a pile machine platform. A hydraulic holding device is arranged in the power head and can clamp the reinforced concrete pile. The power head drives the reinforced concrete pile to rotate up and down at the sametime. The reinforced concrete precast pile forming system and the construction method have the advantages that the outer surface of the pile is designed to form a shape of a screw, the pile is rotatedand sunk into the soil according to the thread shape, so that the pile is completely combined with the soil body, undisturbed soil is not damaged, the friction stress of the circumference of the pileand the soil body is changed into shear stress borne by the soil body, and the friction force of the circumference of the pile is improved by geometric multiples.
本发明提供了一种钢筋砼预制桩成型系统及施工方法。一种钢筋砼预制桩成型系统，包括打桩锤、动力头和钢筋砼桩，打桩锤设置打桩机上端构成竖直打桩机构，打桩锤能够与钢筋砼桩上端接触；动力头设置在打桩平台上，且位于竖直打桩机构下方，动力头和桩机平台之间设有升降缸，动力头中设置液压抱紧器，液压抱紧器能够夹紧钢筋砼桩，动力头带动钢筋砼桩转动同时上下运动。本发明的优点在于：桩的外表设计成螺杆状，并将桩按照螺纹状旋转沉入土中，使其与土体完全结合一致，并且不破坏原状土，使桩周与土体的摩擦受力变成对土体的剪切受力，使桩周的摩擦力成几何倍数的提高。
