Tubular pile joint slurry leakage repairing method

Abstract

The invention provides a tubular pile joint slurry leakage repairing method. Resin and an initiator are adopted to prepare a repairing agent; the slurry leakage joint of the tubular pile is filled with the repairing agent, a slurry leakage gap is repaired, the advantages of the resin that is in liquid state, is good in permeability, has no granular impurities and the like are utilized, the repairing agent can quickly permeate into the slurry leakage gap of the tubular pile, and meanwhile, the initiator in the repairing agent plays a role in accelerating resin solidification, so that the repairing agent can be quickly solidified, pile sinking can be performed after 24 hours after repairing, the slurry leakage gap is effectively filled, and eccentric stress and pile explosion during pile sinking are avoided.

Description

technical field [0001] The invention relates to a technique for repairing pipe pile gaps, in particular to a method and a repairing agent for repairing grout leakage in joints of pipe piles. Background technique [0002] In the production process of pipe piles, due to many factors such as mold defects, lack of mold clamping screws, untightened molds, improper slurry leakage protection measures, etc., there will often be leakage of joints or hoops, resulting in There are gaps, holes, hollowing and other undesirable phenomena, which seriously affect the overall quality of the pipe pile. The traditional joint repair method is to use cement and water, and mix it randomly to obtain a repair agent. Simple smearing, the repair agent cannot penetrate into the joint to effectively fill the grout leakage gap, resulting in unilateral force when the pipe pile is hammered, and pile explosion occurs from time to time, and the traditional repair method is very easy to repair. Cracking, fa...
