Problems solved by technology

[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, falling off, etc.

Embodiment 1

[0023] When using a saturated resin, the saturated resin model is: 3272 saturated polyester resin (oil-free alkyd resin), the main component of the initiator is: anhydrous ethylenediamine, and the ratio of the liquid resin and the initiator is 10:1 Proportion ratio, mortar test mold was used to form the test block, the test time was one day, and the strength was 60.1MPa.

[0024] Repair method:

[0025] Step S1, mixing the liquid resin and the initiator uniformly in a ratio of 10:1 to obtain a repairing agent;

[0026] Step S2. Place the pipe piles with a spreader so that the gaps or holes of the pipe piles face up, so that it is not easy to overflow after adding the repair agent, pour the repair agent into the gaps or holes of the pipe piles, and repeat Several times, stop pouring until the repair agent no longer penetrates into the pipe pile from the gap or hole;

[0027] Step S3, just wait for the repair agent to solidify.

[0028] Step S4. After solidification, if there...

Embodiment 2

[0030] When using unsaturated resin: the type of liquid resin is: Nanbao 111GN, its main components are ethyl acetate, methyl ethyl ketone, PU resin; the initiator is: anhydrous ethylenediamine, and the type of accelerator is: Lubrizol 2063 Accelerator; the ratio of the liquid resin: initiator: accelerator = 10:1:1, using mortar trial mold to form a test block, the test time is one day, and the strength is: 52.3MPa.

[0031] Step S1, mixing the liquid resin, initiator and accelerator uniformly in a ratio of 10:1:1 to obtain a repairing agent;

[0032] Step S2. Place the pipe piles with a spreader so that the gaps or holes of the pipe piles face up, so that it is not easy to overflow after adding the repair agent, pour the repair agent into the gaps or holes of the pipe piles, and repeat Several times, stop pouring until the repair agent no longer penetrates into the pipe pile from the gap or hole;

[0033] Step S3, just wait for the repair agent to solidify.

[0034] Step S4...

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.
