Balloon string type umbrella-shaped anchor rod
The invention discloses a string bag type umbrella-shaped anchor rod which mainly comprises a rod body, an anchoring rod piece used for enhancing pulling resistance, a distraction device and a locking device. Before the anchor rod is inserted into the ground, the air bag is in an uninflated state. After the anchor rod is inserted into the ground, firstly, slurry is injected into the air bag through the inflation inlet, so that the air bag expands rapidly and opens the anchoring rod piece, meanwhile, the slowly-opened anchoring rod piece pulls the pulling piece and the circular ring to move downwards, and after the circular ring reaches the limiting block, the anchoring rod piece reaches the maximum opening angle. And then the grout is stopped from being injected into the air bag, and the grout in the air bag is trapped in the air bag under the action of the one-way valve and solidified and formed in the air bag. And finally, the anchoring rod piece is maintained at a proper opening angle for a long time under the supporting of the air bag and the pulling force of the pulling piece, so that the pulling resistance of the anchor rod is enhanced. The device has the advantages of being simple in structure, convenient to operate and easy to implement.
本发明公开了一种串囊式伞状锚杆，主要包括杆体、以及用于增强抗拔力的锚固杆件、撑开装置和锁紧装置。锚杆插入地面前，气囊处于未充气状态。等锚杆插入地面后，首先通过充气口向气囊注入浆液，使气囊迅速膨胀并撑开锚固杆件，与此同时，慢慢张开的锚固杆件也会拉着拉件和圆环向下移动，待圆环达到限位块后，锚固杆件达到最大的张开角度。接着停止向气囊注入浆液，气囊内的浆液在单向阀作用下被困于气囊内，并在气囊内凝固成型。最后，锚固杆件在气囊的支撑和拉件的拉力作用下长期维持在合适的张开角度，以增强锚杆的抗拔性能。本发明还具有结构简单、操作方便、容易实施的优点。
