Construction method for adjusting rigidity of pile foundation
The invention discloses a construction method for adjusting the rigidity of a pile foundation. The construction method comprises the following steps that the part, extending out of a pile foundation body, of a pile foundation steel bar is protected; concrete is poured to the end of the pile foundation body, and a secondary pouring section is formed; backfilling the mattress layer; the supporting rods penetrate through the anchoring plates, the upper ends of the supporting rods are matched with the anchoring plates in a clamping mode, and the ends, extending out of the mattress layer, of the pile foundation steel bars are fixedly connected with the lower ends of the supporting rods; an elastic buffering assembly is arranged on the anchoring plate; the raft plate is poured, and the elastic buffer assembly is embedded in the raft plate. The protection structure has the beneficial effects that the protection sleeve is used for protecting the pile foundation steel bars, a waterproof, insulated, corrosion-resistant and permeation-resistant multi-layer protection structure is formed on the outer sides of the pile foundation steel bars, and the situation that the durability of the pile foundation steel bars is reduced by a cushion layer and land is avoided; the elastic buffering assemblies are formed at the ends of the pile foundation steel bars, elastic buffering transition between the pile foundation steel bars and the raft is achieved, and therefore the pile foundation can adjust the rigidity according to different conditions, and the stress requirement of a building is met.
本申请公开了一种调节桩基刚度的施工方法，包括如下步骤：对桩基钢筋伸出桩基主体的部分进行防护处理；对桩基主体的端部浇筑混凝土，形成二次浇筑段；进行褥垫层的回填；将托杆穿过锚固板，托杆的上端与锚固板形成卡设配合，桩基钢筋的伸出褥垫层的端部与托杆的下端固定连接；在锚固板上设置弹性缓冲组件；浇筑筏板，弹性缓冲组件埋设在筏板内。本申请的有益效果：利用防护套管对桩基钢筋形成防护，在桩基钢筋的外侧形成防水、绝缘、耐腐蚀、耐渗透的多层保护结构，避免垫层、土地降低桩基钢筋的耐久性；在桩基钢筋的端部形成弹性缓冲组件，实现桩基钢筋与筏板之间的弹性缓冲过渡，从而桩基能够根据不同情况调节自身刚度，满足建筑受力需求。
