Expansion bag type anti-floating anchor rod
The expansion bag type anti-floating anchor rod comprises a reinforcing net and an anchor rod body, the initial end of the anchor rod body is a clamping end, the tail end of the anchor rod body is a tensioning end, a bag is arranged on the peripheral wall of the clamping end of the anchor rod body, a bag cavity is formed between the bag and the anchor rod body, the anchor rod body is provided with a transition hole, the transition hole is formed in the end face of the tensioning end of the anchor rod body, and an open hole is formed in the transition hole. The bag cavity is internally provided with an expanding piece used for expanding the bag before external cement paste fluid is poured into the bag so that the outer circumferential wall of the bag can abut against the inner circumferential wall of the external drill hole in a matched mode, and the reinforcing net is provided with a reinforcing piece used for improving the connecting strength between the anchor rod and a cement paste block body when the external cement paste fluid forms the cement paste block body. The problems that in the prior art, the connection strength between the bag of the bag type anti-floating anchor rod and the drill hole is too low, the grouting efficiency is low due to the fact that the bag is not shaped, and the matching strength between the bag and the drill hole is too low due to the fact that the shape of the bag is irregular after the cement paste fluid in the bag is solidified are solved.
本发明公开了一种扩张囊式抗浮锚杆，包括加强网和锚杆，锚杆始端为卡固端，所述锚杆末端为张拉端，锚杆卡固端外周壁上设置有囊袋，所述囊袋与锚杆之间形成有囊腔，锚杆开设有过渡孔，过渡孔开设置锚杆张拉端端面上并形成有开孔，囊腔中设置有用于在外界水泥浆流体灌注进囊袋前撑开囊袋使囊袋外周壁与外界钻孔内周壁抵接配合的撑开件，加强网上设置有用于在外界水泥浆流体形成水泥浆块体时提高锚杆与水泥浆块体之间连接强度的加强件。本发明解决了现有技术中囊式抗浮锚杆的囊袋其与钻孔之间连接强度过低、囊袋灌注水泥浆流体受囊袋不定形影响灌注效率低下以及囊袋中水泥浆流体凝固后囊袋形状不规则导致囊袋与钻孔之间配合强度过低的问题。
