Variable cross-section anchor rod suitable for soft stratum
The invention discloses a variable cross-section anchor rod suitable for soft stratum.The variable cross-section anchor rod comprises a steel bar anchor rod, a reinforcing steel bar, a plurality of anchoring devices and an anchor rod end device, the reinforcing steel bar and the steel bar anchor rod are welded into a whole, and each anchoring device comprises a fixed support, a fixed thin iron pipe, a rotary support, an anchor piece, a rib plate and an anchor piece pedestal; the fixed support is welded between the two steel bar anchor rods, the fixed thin iron pipe is welded at the included angle between the fixed support and the steel bar anchor rods and serves as a constraint component of the rotary support, the rotary support is a solid steel pipe and is inserted into the fixed thin iron pipe, rib plates are welded to back plates on the two sides of the anchor piece respectively, and the anchor piece and the rib plates are welded to the rotary support to form a rigid body. The anchor piece pedestal is welded between the two steel bar anchor rods. The anchoring device is arranged, the anchor piece is embedded into the soft stratum through the self weight and external tension, and the bearing capacity of the anchor rod is remarkably improved.
本发明公开了一种适用于软弱地层的变截面锚杆，包括钢筋锚杆、加强钢筋、若干个锚定装置和锚杆端头装置，加强钢筋与钢筋锚杆焊接为一体，锚定装置包括固定支座、固定薄铁管、旋转支座、锚片、肋板和锚片垫座，固定支座焊接于两钢筋锚杆之间，固定薄铁管焊接于固定支座与钢筋锚杆夹角处，作为旋转支座的约束构件，旋转支座为实心钢管，插接在固定薄铁管中，锚片两侧背板各焊接有肋板，锚片和肋板焊接于旋转支座构成一刚体，锚片垫座焊接于两钢筋锚杆之间。本发明通过设置锚定装置，利用其自重及外加拉力使锚片嵌入软弱地层，显著提升锚杆的承载力。
