04 / Installation
Application Guide
- 01Working principle — uses a stainless ball check valve at the head to prevent backflow under high-pressure injection
- 02Drill the substrate at the specified diameter (14 mm bore) along the crack
- 03Insert the packer into the bore; tighten with the T-handle wrench to expand the rubber sleeve
- 04Connect the high-pressure pump to the packer head and begin injection
- 05On completion, snap off the protruding aluminum shaft flush with the substrate
- Stable operation at ≥ 20 MPa — no field tuning required
- Simple installation — high site productivity
- Suitable for cracks, joints, soft soils, and roof / wall / column repair
- Used with both standard and reinforced crack injection systems
05 / Storage & Safety
Transport, Storage & Safety
Storage & Transport
Store in original packaging in a dry indoor environment away from corrosive chemicals. No special temperature requirements.
Shelf Life
No fixed expiration when stored properly. Inspect rubber sleeves for aging before each batch use.
Precautions
- Inspect rubber sleeve and check valve before each use; discard if damaged
- Use only with compatible high-pressure injection pumps
- Tighten with the specified T-handle wrench — do not over-torque
- Verify expansion seal inside the bore before pumping
- Snap off the protruding aluminum shaft flush with the substrate after injection
