Combined anti-floating anchor rod and construction method
The invention discloses a combined anti-floating anchor rod which comprises a steel bar rock-entering section, a connecting mechanism and a steel bar anchoring section. The steel bar rock-entering section is arranged in the anchor rod hole, and grouting is conducted in the anchor rod hole; the upper ends of steel bars of the steel bar rock-entering section are welded with the connecting mechanism; the lower ends of steel bars of the steel bar anchoring section are connected with the connecting mechanism in a steel bar mechanical connection mode; rebars of the rebar anchoring section are radial, and the upper ends of the rebars sequentially penetrate through the foundation cushion layer and the foundation waterproof layer and then extend out of the waterproof protection layer. The invention further discloses a construction method of the combined anti-floating anchor rod. The problems that in existing anti-floating anchor rod construction, an anchor rod pile head is damaged, anchor rod reinforcing steel bars are seriously disturbed, and the foundation earth excavation efficiency is low can be solved.
本发明公开了一种组合式抗浮锚杆，其包括钢筋入岩段、连接机构、钢筋锚固段；钢筋入岩段置于锚杆孔中，锚杆孔内有注浆；钢筋入岩段的钢筋的上端与连接机构焊接连接；钢筋锚固段的钢筋的下端与连接机构采用钢筋机械连接方式连接；钢筋锚固段的钢筋呈放射状，其上端依次穿过基础垫层、地基础防水层后，伸出防水保护层。本发明还公开了一种组合式抗浮锚杆的施工方法。本发明能解决现有抗浮锚杆施工存在的锚杆桩桩头破坏、锚杆钢筋扰动严重，以及基础土方开挖效率低等问题。
