Abstract

The invention relates to an injection head for an injection bore anchor, comprising a flushing head with an outer housing with at least one supply connection for supply of at least one supply component and an inner piece, housed within the outer housing, rotatably about a longitudinal axis, wherein the inner piece has a rear side connector with a housing opening for a rotational positive fit housing of a connector end of a bore drive and a front side connector means for connection of an anchor rod. According to the invention, an advantageous modification can be achieved wherein one or more securing elements (64) are provided, the inner piece (4) has one or more assembly openings (68) in a longitudinal section (67) of the housing opening (10) on at least one cross section, suitable for detachable fixing of the securing element(s) and in the fixed state of the securing element(s) a cross sectional reduction of the housing opening is achieved with relation to the state without securing elements. The invention further relates to an injection head, the inner piece (4) of which is provided on the front side thereof with a threaded drilling (17) having an internal thread (16) and over the length of which there is a recess (26), in which an injection rod may be inserted, wherein the injection rod may be connected in a sealing manner in a front longitudinal section with the outlet opening to an injection channel of a screwed in anchor rod.
