Recyclable PRC support pile and construction technology
The invention relates to the technical field of support piles, in particular to a recoverable PRC support pile and a construction technology, the recoverable PRC support pile comprises a pile body, the bottom end of the pile body is fixedly connected with a bottom plate, the bottom plate is a steel plate permanently installed at the bottom of the pile, when the pile body needs to be recovered, a guide rope is used for guiding and replacing a lifting rope, the guide rope is a nylon rope, and the lifting rope is a steel strand; the two ends of the steel strand are fixed to hoisting equipment, the pile body is hoisted and recycled, upward pulling force is transmitted to the steel plate at the bottom of the pile through the steel strand, the steel plate extrudes and lifts the pile body to be slowly lifted, the PRC pile is in a pressed state all the time, and the problem that concrete is prone to cracking due to tension in the pulling-out process is solved; meanwhile, in consideration of durability and reusability of the steel strand, a nylon rope with good corrosion resistance is reserved in the pile when the steel strand is not used, and the steel strand is guided to replace the nylon rope to hoist the pile when the steel strand is used, so that reusability of the PRC support pile is realized.
本发明涉及支护桩技术领域，具体涉及一种可回收的PRC支护桩及施工工艺，包括桩体，桩体的底端固定连接有底板，底板为永久性安装于桩底的钢板，需回收桩体时，通过引导绳引导替换吊绳，引导绳为尼龙绳，吊绳为钢绞线，将钢绞线的两端固定至起吊设备上，将桩体起吊回收，上拔力通过钢绞线传递给桩底的钢板，通过钢板挤压抬升桩体缓慢提升，PRC桩始终处于受压状态，避免了在拔出过程中混凝土受拉容易开裂的问题，同时考虑到钢绞线的耐久性和可重复使用，在不使用的时候预留防腐性能好的尼龙绳在桩内，等使用的时候再引导钢绞线代替尼龙绳起吊桩，实现PRC混凝土支护桩的反复使用。
