The invention discloses a construction method of a
basement gravel filling grouting anti-floating anchor rod. A jumbolter is used for
pipe-following drilling,
impact holing is conducted, the gravel filling grouting anti-floating anchor rod is arranged for connecting building or structure bases with overlaying bedrocks into an integral and resisting the
buoyancy of underground water together with an upper part structure. Compared with a traditional anti-floating anchor rod construction technology, the quality of a gravel filling grouting body is more stable, construction is faster, and
pipe blocking is not caused during grouting so that the quality of the grouting body is not affected; the construction
noise is low, working, studying, and relaxing of people are generally unaffected, the surrounding environment is not affected in a bad way. According to the construction method of the
basement gravel filling grouting anti-floating anchor rod, the construction device is simple, operation is simple, the construction period is short, the labor intensity is low, the hole forming speed is fast, and the qualified rate of the quality of an anchor rod is high;
cement is saved, the cost is lowered, the quality of the anchor rod can be effectively controlled, and the performance risk is reduced.
