Pile hammer device and precast pile construction equipment
The invention provides a pile hammer device and precast pile construction equipment. The pile hammer device comprises a pile cap, a hammering mechanism and a connecting frame. A first through hole is formed in the middle part of the pile cap, the hammering mechanism is installed on the pile cap, a second through hole is formed in the middle part of the hammering mechanism, and the connecting frame is arranged on the hammering mechanism. During use, the connecting frame is used for being connected with a power head of a drilling machine, the pile cap is used for being connected with a precast pile, and the first through hole and the second through hole are used for allowing a drill rod to pass through and communicating with the hollow part of the precast pile. By the adoption of the technical scheme, the problem that the precast pile is difficult to sink in a hard soil layer is solved, the pile sinking quality is remarkably improved, and the construction efficiency is remarkably increased. According to the technical scheme of the invention, soil is not taken, and only part of soil plugs in the pipe pile or end resistance of hard soil layers is damaged, so that sinking of the precast pile can be facilitated, side resistance is hardly affected, and meanwhile the pile end bearing capacity of the formed pile is guaranteed.
本发明提供了一种桩锤装置及预制桩施工设备。该桩锤装置包括桩帽、锤击机构和连接架。其中，桩帽的中部形成第一通孔，锤击机构安装在桩帽上，锤击机构的中部形成有第二通孔，连接架设置在锤击机构上。在使用时，连接架用于与钻机动力头相连，桩帽用于与预制桩相连，第一通孔和第二通孔用于通过钻杆并与预制桩的中空部分相连通。采用本发明的技术方案，解决了预制桩在硬土层中遇见的沉桩困难的问题，显著提高了沉桩质量及施工效率。本发明的技术方案不取土，仅破坏管桩内部分土塞或者硬土层端阻，就可以方便预制桩下沉，几乎不影响侧阻力，同时保证了成桩的桩端承载力。
