Background
In the construction of underground structures in building engineering, a bag-type enlarged head anchor rod is often adopted to improve the anti-floating capacity of a foundation slab. Through piling downwards from the bottom of the foundation pit, and injecting cement paste into the pile hole, the anchor rod needs to be put into the cement paste in time when the cement paste is in a flowing state, and then the cement paste is also injected into the bag body of the anchor rod. After the cement paste is solidified, the capsule forms an enlarged head at the bottom of the anchor rod, so that the anti-floating effect of the anchor rod is improved.
However, the deeper the capsule is buried, the stronger the squeezing action of the grout in the pile hole on the capsule. When the anchor rod is lowered, the balloon body which is not injected with the grouting liquid is shrunken, and the confining pressure generated by the cement paste outside the balloon body is resisted by the cement paste which is injected later, so that the balloon body is unfolded outwards. Therefore, the empty bag is easy to collapse by external cement paste, and the problem that the empty bag is fully filled with cement paste after being not fully unfolded exists, so that the bearing capacity of the anchor rod cannot be fully utilized.
