DEVICE FOR THE SUBSEQUENT STABILISATION OF WATER-PERMEABLE GAP CHAMBER BREAKS IN BRIDGES, TUNNELS AND BUILDINGS

摘要

The application comprises devices of a joint-injection system for the subsequent stabilization of water-permeable joint chamber / concrete coverings in bridges, tunnels and buildings coated with a reusable sealing cushion valve in length and width on the outside with a self-adhesive at least 480 g / m 2 Sealing fleece sealing tape, are attached, which has on the longitudinal side and the transverse side inside pressure-resistant closures with a diffusion rate of 0.73 mbarl / year and is filled or evacuated via a plastic-coated, metal compressed air valve with valve extension and depending on the requirements with a joint injection System the joint chamber and concrete cracks can be filled with grout. The devices consist of an injector feeder, swelling-fleece-injector-system and grout-stopper, which are factory or factory attached to the sealing pad valve or provided by the customer by means of a push-grout-injection micro-cable tube, swell-injector-system and grout-stopper can be pushed over the sealing pad valve.
