Anti-corrosion water-stopping anchor rod
An anti-corrosion water-stopping anchor rod comprises an anchor rod body and an anchoring structure on the top, wherein the anchor rod body is a main reinforcing steel bar, the main reinforcing steel bar is made of a bonded or unbonded finish-rolled threaded reinforcing steel bar, a steel strand and a prestressed pull rod, the top of an anchor rod piece is anchored to a building bottom plate, the bottom of the anchor rod piece is anchored to a straight-through section or an expanded head section anchor head concrete solidification material, and the concrete solidification material is combined with an anchor head and the main steel bar to form an anchor rod pile system; the anchoring structure at the upper end of the main reinforcing steel bar adopts a high-strength nut three-piece set or three-way high-strength nut or high-strength nut flange anchoring structure, and the concrete solidification material is poured; the expanded head section is an expandable end plate, a ground anchor, a bearing plate, a fixed-diameter anchor head or a tree-root-shaped expanded head, a variable-diameter reinforcement cage, a fiber cage or a bag type or combined bag type expanded head; a sealing ring or a sealing gasket which is made of a water-swelling sealing material is arranged on the main reinforcing steel bar of the anchor rod at the anchoring part of the top and the bottom of the anchor rod piece or at the anchoring combination part of the bottom of the top-added anchor rod piece and the anchor head of the straight-through section or the expanded head section; at least one waterproof and anti-corrosion layer is sequentially arranged around anchor holes in the anchoring positions of the top of the anchor rod piece and the bottom plate; and 1-2 circles of water-swelling sealing strips are arranged at the positions, close to a waterproof protection layer, of the main steel bar.
一种防腐止水锚杆，包括锚杆杆体和顶部的锚固结构，锚杆杆体即主钢筋，主钢筋采用有粘结或无粘结精轧螺纹钢筋、钢绞线、预应力拉杆，锚杆杆件顶部与建筑物底板锚固、锚杆杆件底部与直通段或扩大头段锚头混凝土凝固材料锚固，混凝土凝固材料结合锚头和主钢筋而形成锚杆桩系统；主钢筋上端的锚固结构采用包括高强螺母三件套或三通高强螺母或高强螺母法兰锚固结构并浇筑混凝土凝固材料；扩大头段为可拓展端板、地锚、承压板、固定直径锚头或树根状扩大头、变直径钢筋笼、纤维笼或囊式或组合囊式扩大头；锚杆杆件顶部与底部锚固处或现上加锚杆杆件底部与直通段或扩大头段锚头锚固的结合处在锚杆的主钢筋上设有遇水膨胀密封材料密封圈或密封垫；锚杆杆件顶部与底部底板锚固处的锚孔周围依次分别设置起码一层防水防腐层；在靠近防水保护层附近的主筋位置设置1‑2圈的遇水膨胀密封条。
