Construction combination structure and construction method of retard-bonded prestressed anti-corrosion anti-floating anchor rod
The invention relates to the technical field of anti-floating anchor rods, and discloses a slow-bonding prestressed anti-corrosion anti-floating anchor rod construction combined structure which comprises an anchor rod body, a concrete cushion layer and a bottom plate, the bottom plate is located at the top of the concrete cushion layer, and the top end of the anchor rod body penetrates through the concrete cushion layer and extends into the bottom plate. A prefabricated rod core is arranged in the anchor rod body. According to the construction combined structure of the retard-bonded prestressed anti-corrosion anti-floating anchor rod, the pile head steel pipe and the steel plate water stop ring are installed, the diameter of the pile head steel pipe is 10 mm larger than that of the anchor hole, the concrete cushion layer is poured, after pouring is completed, the height of the pile head steel pipe is larger than the thickness of the concrete cushion layer, a pile head is integrally formed, secondary construction for pile head making and bottom plate pouring are not needed, and the construction cost is reduced. The anchor rod body extends into the bottom plate structure in a pile head mode, a sinking type small bearing platform excavation procedure is omitted, the construction efficiency is improved, meanwhile, damage to the rod body and surrounding foundation shallow rock mass caused by excavation is reduced, and the anchor rod construction quality is guaranteed.
本发明涉及抗浮锚杆技术领域，且公开了一种缓粘结预应力防腐抗浮锚杆施工组合结构，包括：锚杆本体、混凝土垫层和底板，所述底板位于混凝土垫层的顶部，所述锚杆本体的顶端穿过混凝土垫层延伸至底板的内部，所述锚杆本体的内部设置有预制杆芯。该缓粘结预应力防腐抗浮锚杆施工组合结构，安装桩头钢管及钢板止水环，桩头钢管的直径大于锚孔直径10mm，浇筑混凝土垫层，浇筑完成后，桩头钢管的高度大于混凝土垫层的厚度，一体形成桩头，不需要二次施工做桩头，再浇筑底板，锚杆本体以桩头型式伸入底板结构，减少了一道下沉式小承台开挖工序，提高了施工工效，同时降低开挖对杆体及周边基础浅层岩体的破坏，保证了锚杆施工质量。
