Device and method for breaking pile head of foundation pile
The invention relates to a device and method for breaking a pile head of a foundation pile, and belongs to the technical field of concrete filling piles. The method for breaking the pile head of the foundation pile comprises the following steps: 1, erecting the breaking device, and arranging the breaking device on a super-pouring part of the cast-in-place pile before concrete is preliminarily solidified; 2, cutting the pile head of the cast-in-place pile, enabling the cut material to form high-speed water flow in the breaking device through a high-pressure device to be used for cutting the pile head of the cast-in-place pile; and 3, cleaning the pile head, removing the breaking device and discharging waste liquid in a template after the breaking device finishes cutting, removing the template after the concrete is preliminarily solidified, and washing to expose steel bars. According to the method, the pile head of the foundation pile can be effectively broken, and the damage to a main reinforcement can be reduced in the breaking process.
本发明涉及一种破除基桩桩头的装置和破除基桩桩头的方法，属于混凝土灌注桩技术领域。破除基桩桩头的方法，包括以下步骤：步骤一：架设破除装置，在混凝土初凝前将破除装置布置在灌注桩超灌部分；步骤二：切割灌注桩桩头，通过高压装置将切割料在破除装置中形成高速水流，用以切割灌注桩桩头；步骤三：清洗桩头，在破除装置完成切割后，撤出破除装置并排出模板中的废液，待混凝土初凝后拆除模板并冲洗露出来钢筋。通过本发明的方法能够有效地破除基桩桩头，并且在破除过程中能够减少对主筋的破坏。
