5. Construction method
(1) High-pressure grouting method
) Use a high-pressure cleaning machine to inject clean water into the grouting nozzle at a high pressure, observe the water outlet situation, and remove the dust in the joints. Clean well.
) Clean and inspect in detail, analyze leakage, and determine the location and spacing of grouting holes. Clean the area to be constructed, remove precipitates on the concrete surface, and ensure that the surface is clean and moist.
) Use drilling tools such as electric hammers to drill holes along both sides of the crack. The diameter of the drill bit is , the drilling angle should be ≦, the drilling depth ≦ the thickness of the structure, and the drilling must pass through the crack. However, it is not allowed to penetrate the structure (except for grouting behind the wall). The distance between drilling and cracks is ≦/thickness of the structure. Drilling spacing~
) Install the grouting nozzle (also called a water stop needle) in the drilled hole and tighten it with a special hex wrench so that there is no gap between the grouting nozzle and the drilled hole and no water leakage.< br/>) Seal the crack surface where water seepage occurs during seam cleaning with quick-drying cement in order to prevent the grout from running when the chemical grout is poured.
) Grouting uses a high-pressure grouting machine to pour chemical grouting material into the grouting holes. The grouting sequence of the facade is from bottom to top. The grouting sequence can start from one end, and the single holes can be continued one by one. When the adjacent holes start to produce grout, maintain the pressure for ~ minutes, then stop grouting in this hole and inject adjacent grouting holes instead.
) After removing the nozzle and grouting, remove or knock off the exposed grouting nozzle after confirming that there is no leakage. Clean up any spilled grout that has solidified.
) Use quick-drying cement to repair and seal the grouting opening.
(2) Construction technology of static grouting
Crack inspection: If the crack size is about 10% and there is no water seepage on the surface, static grouting treatment shall be used.
. Crack treatment: Clean the area that needs to be constructed, chisel away the precipitates on the concrete surface, make sure the surface is clean and dry, and use alcohol to clean the superficial layer of the crack and the surface that needs to be sealed.
. The installation sequence of the base is from bottom to top. The flat surface can start from one end, and the single holes can be installed continuously one by one. The installation distance between the bases is less than
. Use special sealing glue or other anchoring glue to seal the cracks as needed. When filling cracks, pay attention to fully sealing them and leaving an observation opening at the top of the cracks.
, sealing inspection, check the sealed cracks to ensure that there are no air leaks,
, glue preparation, mix the grouting glue according to the factory required ratio, try to mix the amount of glue according to the amount used, do not mix too much to avoid waste.
, Perfusion: Inhale the prepared colloid into the perfusion device, install the perfusion device on the base, and pour it. The perfusion time is generally an hour. In practice, the glue does not run out of the perfusion device, and an observation port is reserved for the glue to come out
If the colloid in the infusion device is completely filled, it needs to be filled again.
, remove the perfusion device, curing and curing. After filling, the perfusion device should be removed in time. The base should be blocked with a plug. The base and sealing parts can be removed after leaving it for an hour for curing and curing.
