Aluminium 13*100mm Grouting Injection Packer
Packer,also named grout nipple, widely used in the waterproofing work,especially in
the concrete structurewithPolyurethane grout and epoxy resin grout. With high pressure
chemical grout injection technology,the packer is the special tools in this sector.
Principle under the continuous pressure from injection pump to inject the grout into the concrete
cracks and holes,squeeze out the water in cracks. Make the grout foam in the holes and cracks
to complete the waterproof work.
The important part for high pressure injection pump--high pressure Packer.
Using the principle of ring crush fastening to stop the leaking water. There is a one-
way valve in the head to stop the grout flow back in thehigh pressure. The expansion part is
made of rubber ring,whose diameter is 13mm,to put into the hole diameter 14mm.Fasten the pre
ssure-ring bolt and press the rubber part to make the grout liquid inject into the holes.
The one-way valve could be opened above pressure 0.4KN, therefore, the injecting
pressure should be higher than0.4KN.
For the dense type concrete structure,usually choose the packer 70*80mm;
For the loosely concrete structure usually choose the packer 100-150mm;
