Pile head cutting method
The invention relates to a pile head cutting method, which is characterized in that a casing pipe is sleeved on a main reinforcement corresponding to a to-be-cut position of a pile head, and the cutting method comprises the following steps: S1, marking an annular tangent line on the circumferential surface of a pile foundation corresponding to the to-be-cut position of the pile head, so that the part above the annular tangent line is the to-be-cut pile head, and the part below the annular tangent line is a bearing platform pile foundation; s2, concrete on the periphery of the reinforcement cage is cut in the circumferential direction along the circumferential tangent line to form an annular groove, and the concrete is cut upwards from the annular groove to strip out the reinforcement cage with a concrete core; and S3, steel chisels are horizontally hit into the central axis of the reinforcement cage from the periphery of the reinforcement cage, so that the concrete core is broken. The technical problems that in the prior art, when a pile head is broken, main reinforcements of a reinforcement cage are prone to being damaged, and the integrity of pile foundation concrete is damaged are solved. Concrete on the periphery of the reinforcement cage is annularly cut through an annular cutting method, the pile edge can be prevented from being damaged, and the integrity of bearing platform pile foundation concrete is improved.
本发明涉及一种桩头切割方法，在主筋上对应于桩头待切割位置处套设套管，切割方法包括如下步骤：S1、在桩基的周面上对应于桩头待切割位置标注环切线，使环切线以上部分为待切割的桩头，环切线以下部分为承台桩基；S2、沿着环切线环向切割钢筋笼外围混凝土形成一个环形槽，自环形槽起向上切割混凝土以剥离出带有混凝土芯的钢筋笼；S3、自钢筋笼外周向该钢筋笼的中轴线水平打入钢钎，以使混凝土芯断裂。本发明解决了现有技术中破除桩头时容易损伤钢筋笼主筋和损坏桩基混凝土完整性的技术问题。本发明采用环切法环向切割钢筋笼外围混凝土，能够避免破坏桩边，提高承台桩基混凝土的完整性。
