Mechanical Surface Grouting Packer

Mechanical cement grouting packer is a reusable grouting plug that is inserted into the grouting hole and then secured in the hole using the principle of mechanical expansion rubber.
purpose
1. Water injection, grouting, dust reduction, coal cracking, gas discharge, and subsequent hole plugging in coal or rock mass.
2. Curtain, consolidation, backfilling, chemical grouting, and cement grouting for hydropower stations and reservoir engineering.
3. Geological exploration water pressure test and drilling for water blocking, consolidation, etc.

Mechanical grouting packerin the grouting hole, by mechanical pressure to make the rubber plug (seal) transverse, and the hole wall is tight, the grouting hole is divided into upper and lower two sections, so that the grouting of the lower section can be put into the grout crack water-bearing rock, but not from the rubber plug back to the upper section of the hole, or even the surface, to ensure normal subsection grouting. Grouting refers to the index that should be achieved after the grouting is required by the designer. Because of the different grouting engineering properties and engineering address conditions are different, the purpose and requirements of each grouting are not the same, so it is difficult to provide a more specific and unified criteria, but can only make specific rules according to the specific situation
