Anti-drawing corrosion-resistant anti-floating anchor rod device
An anti-drawing corrosion-resistant anti-floating anchor rod device comprises an anchor rod assembly vertically arranged in an anchor rod hole, and the anchor rod assembly comprises an anchor rod body, an anti-inclination unit and a counter-force unit, and the anti-inclination unit and the counter-force unit are arranged on the anchor rod body; the anchor rod hole comprises a non-expanded head section and an expanded head section which are vertically through, and the anti-inclination unit and the counter-force unit are anchored in the non-expanded head section and the expanded head section respectively; the counter-force unit comprises an expanding mechanism arranged on the outer ring of the anchor rod body, a fastening mechanism arranged on the lower side of the expanding mechanism and connected with the anchor rod body, and an extrusion piece arranged on the upper side of the expanding mechanism, capable of vertically moving along with the anchor rod body and pressing the expanding mechanism downwards to be expanded, and the inner diameter size of the non-expanded head section is smaller than the maximum diameter size of the expanded expanding mechanism. The design of the opening mechanism and the centering piece improves the drawing resistance of the device, a large stress area is formed after the opening mechanism is unfolded, the drawing force is evenly dispersed, the stress concentration phenomenon in the device is relieved, meanwhile, the main body material of the device is a corrosion-resistant material, the service life of the device is prolonged, and the durability of the device is improved.
一种抗拉拔的耐腐型抗浮锚杆装置，包括竖向设于锚杆孔内的锚杆总成，锚杆总成包括锚杆体及其上的防倾斜单元和反力单元；锚杆孔包括上下贯通的非扩大头段和扩大头段，防倾斜单元和反力单元分别锚固于非扩大头段和扩大头段内；反力单元包括设于锚杆体外圈的撑开机构及其下侧与锚杆体连接的紧固机构，以及设于撑开机构上侧且能够随锚杆体竖直移动，并将撑开机构下压展开的挤压件，且非扩大头段的内径尺寸小于撑开机构展开后的最大直径尺寸。撑开机构和对中件的设计提高了本装置的抵抗拉拔能力，撑开机构展开后形成的较大受力面积，均匀分散了拉拔力，减缓了装置中应力集中现象，同时，本装置的主体材质为耐腐型材料，提高了装置的使用年限和耐久性。
