Water-stop needle high-pressure perfusion injection needle high-pressure grouting nozzle Made in Taiwan (E035-10075)

feature of product:

• Water-stop needles (injection needles, high-pressure grouting nozzles) made in Taiwan
• High pressure filling machine accessories
• The water-stopping needle is firmly fixed in the hole by a quick tightening device after drilling the concrete, and is connected to the high-pressure pipe by a quick connector. When the agent is injected into the hole, there is a check valve device to prevent the resin from flowing back after high-pressure pouring. .

High-pressure pouring and leak-stopping method:
Structural cracks and water leakage treatment

1. Drill at an angle of 45 degrees at 5 cm to 10 cm to the left or right of the lowest point of the crack to half the thickness of the structure. Drill from low to high in sequence. The hole spacing is preferably 15 cm to 30 cm. Drill to the highest point before drilling again. Bury the water stop needle once.
2. Since cracks in general structures are irregular, special attention must be paid to drilling holes that must cross the fracture surface for injection to be effective. (To achieve good results, the distance between holes can be shortened)
3. After the water-stop needle is installed, first check the structural strength of the structure; if the structural strength is insufficient, use a high-pressure infusion machine to inject a single-liquid hydrophobic foaming agent until the injection material is found to ooze out on the surface of the structure.
4. After the filling is completed, the water-stop needle can be removed after the material is completely solidified.

Treatment of water leakage in construction joints

1. Drill holes 5 cm to 10 cm to the left or right of the lowest point of the construction joint at an angle of 45 degrees to a depth of 1/2 of the thickness of the structure. Drill from low to high. The appropriate hole spacing is 15 cm to 30 cm. After reaching the highest point, bury the water-stop needle again. Since cracks in general structures are irregular, special attention must be paid to drilling holes that must cross the crack surface. Injections are effective.
2. After the water-stop needle is set, use a high-pressure infusion machine to inject the water-stop foaming agent until the foaming agent is found to seep out on the surface of the structure.
3. After the pouring is complete, the water-stop needle can be removed after the material is completely solidified.
4. If the water seepage still cannot be improved, just use a water-stop foaming agent to repair it.

Honeycomb water leakage treatment

1. In the honeycomb area, drill a hole every 25cm to 30cm, with a depth of 1/2 of the thickness of the structure, and then bury the water-stop needle and tighten it.
2. After the water-stop needle is set, use a high-pressure infusion machine to inject the water-stop foaming agent until the foaming agent is found to seep out on the surface of the structure, which can completely solve the water leakage problem.
3. After the pouring is complete, the water-stop needle can be removed after the material is completely solidified.

Water leakage from ring cracks

1. First, drill directly at the crack of the ring piece. The drilling depth must exceed the thickness of the ring piece. Bury the water-stop needle and then inject the water-stop foaming agent;
2. Then drill a hole 5cm to 10cm to the left or right of the ring piece at an angle of 45 degrees to a depth of 1/2 of the ring piece thickness, bury the water-stop needle, and inject the water-stop foaming agent again.
3. After the pouring is complete, the water-stop needle can be removed after the material is completely solidified.

Water seepage between ring pieces

1. Drill holes at the water seepage between the ring plates first. The drilling depth must exceed the thickness of the ring plates.
2. Bury the water-stop needle and then inject the water-stop foaming agent.
3. After the pouring is complete, the water-stop needle can be removed after the material is completely solidified.

Grouting hole water seepage

1. Drill a 5mm hole directly on the pouring hole cover
2. Then inject the water-stop foaming agent through this hole.
3. After the pouring is complete, the water-stop needle can be removed after the material is completely solidified.
