The invention discloses a repairable bottom heave control method which comprises the following steps: drilling a pile hole, inserting profile steel, inserting repeatable grouting tubes at two outer sides of a profile steel flange, injecting solidifying slurry into the pile hole through the repeatable grouting tubes, and constructing an anchor cable hole; enabling the diameter of the anchor cable hole to be slightly greater than the enveloping diameter of an anchor cable rib material and the repeatable grouting tubes, inserting the anchor cable rib material with the repeatable grouting tubes according to the principle that the rib material is relatively convenient to convey, and injecting cement slurry into the anchor cable hole through the repeatable grouting tubes; and during construction of a crown beam, isolating the exposed anchor cable rib material with a soft sleeve or an externally enveloped material, making an anchor surface into a plane vertical to the extension direction of the rib material so as to be convenient for tensioning and locking an anchor cable, and after the construction of the crown beam is completed for 7 days, tensioning and locking the anchor cable. The method disclosed by the invention has the beneficial effects that by repeated grouting, a pile anchor can be dynamically repaired in time, the environmental stability of a pile anchor system can be realized, and the stability of the pile anchor system can be kept for a long time.
