Anti-floating pile construction method based on retard-bonded prestressed steel strands
The invention relates to the field of anti-floating construction, and discloses an anti-floating pile construction method based on a retard-bonded prestressed steel strand, which adopts the retard-bonded prestressed steel strand to realize construction of an anti-floating pile, does not need to reserve a hole channel in the anti-floating pile, does not need hole channel grouting, simplifies the construction complexity of a pile foundation, and improves the construction efficiency. And the prestress effect of bonding prestress is also exerted. The retard-bonded prestress has the characteristics that the defects that the bonded prestress technology is complex in construction and the grouting quality is difficult to guarantee are overcome, and meanwhile, the advantages that the unbonded prestress technology is few in construction technological process and fast in construction progress are also absorbed. Direct contact between the concrete and the prestressed steel strands is achieved, and the problems that the adhesion degree of prestressed tendons and the concrete is low and construction is miscellaneous in existing prestressed anti-floating construction are solved.
本发明涉及抗浮施工领域，公开了一种基于缓粘结预应力钢绞线的抗浮桩施工方法，该方法采用缓粘结预应力钢绞线实现抗浮桩的施工，不需要在抗浮桩中预留孔道，不需要孔道灌浆，简化了桩基的施工复杂度，并且还发挥了有粘结预应力的预应力效果。缓粘结预应力的特点是避免了有粘结预应力技术施工复杂，灌浆质量难以保证的缺点，同时也吸取了无粘结预应力技术施工工艺流程少、施工进度快的优点。实现了混凝土与预应力钢绞线的直接接触，解决现有的预应力抗浮施工预应力筋与混凝土粘合度低，以及施工发杂的问题。
