Height-limiting clamping type hydraulic hammering piling construction method and piling machine
The invention belongs to the technical field of pile foundation construction, and discloses a height-limiting clamping type hydraulic hammering pile driving construction method and a pile driver, and the method comprises the following steps: S1, pile driver in-place, S2, pile hammer installation and leveling, S3, pile lifting and feeding, S4, pile pressing position alignment, and S5, pile pressing and feeding. The invention further discloses a hydraulic hammering pile driver. By synchronously improving the structural design and the construction method, the pile body of the precast pile to be constructed can penetrate through the pile hammer, the height of the pile frame is greatly reduced, the gravity center of equipment is also greatly reduced, the overturning risk is reduced, and the minimum construction height of the precast pile during construction is close to the length of a single-section precast pile; the minimum construction height required during construction is greatly reduced, so that the method can be suitable for being used in a low-clearance scene; the side face of the pile body is held tightly through the pile clamping wedge blocks of the wedge block type pile holding device, so that the hammered force bearing point of the pile moves to the circumferential side face of the pile body instead of the pile end, and the problem that the pile head bursts is avoided.
本发明属于桩基础施工技术领域，公开了一种限高抱夹式液压锤击打桩施工方法及打桩机，该方法包括以下步骤：S1、桩机就位，S2、打桩锤安装调平，S3、吊桩喂桩，S4、压桩位置对准，S5、压桩送桩。本发明还公开了液压锤击打桩机。本发明通过对结构设计与施工方法的同步改进，使待施工预制桩的桩体能穿过打桩锤，桩架高度大幅降低，设备重心也大幅降低，降低倾覆的风险，并使预制桩施工时的最小施工高度接近于单节预制桩桩长；本发明施工时所需的最小施工高度大幅减少，从而能适用于低净空的场景中使用；通过楔块式抱桩装置的夹桩楔块抱紧桩体侧面，使桩受锤击受力点移至桩体的周向侧面，并非在桩端，避免出现桩头爆裂的问题。
