Abstract (en)

[origin: EP3184732A1] A method and an arrangement for the injection of rock or soil material, for example injection into boreholes in correlation with tunnelling, the excavation of rock caverns, or during the construction of dams. Grout from a common supply pump (1) is pumped at the same time through several injection pipes (3) to several injection holes (A-G), and where at least the pressure (10) and injected volume (9) are monitored and individually measured by a control unit for the supply to each one of the said injection holes (A-G), and where the control unit (11), at a final interruption of the injection of an injection hole (A-G), regulates a valve arrangement (4) such that no grout is any longer fed to the injection pipe (3) that leads to the relevant injection hole (A-G) and instead connects a water line (6) for the supply of water to the valve arrangement (4) and the injection pipe (3) for the rinsing clean of these. The arrangement comprises a pressure sensor (10) and a flow gauge (9) for each injection pipe (3) connected to a monitoring arrangement (11) in order to, for each one of the injection pipes (3) of injection holes (A-G), record the pressure and the volume of the supplied grout that has been injected.
