Abstract (en)
[origin: EP0421072A1] 2.1 Injection packers for injecting synthetic resin into the cracks of concrete are driven into drillholes, so that epoxy resin can be injected through the injection packer under high injection pressure. 2.2 The injection packer wedges in the drillhole, the splaying forces occurring being transferred into the depth of the drillhole by a sealing sleeve arranged on the front end of the injection packer. The sealing sleeve comprises a softer plastics material than the plastics injection packer body, which receives the spray nipple. <IMAGE>
