<p>An injection plug device for injecting a concrete repairing agent into a concrete construction (A,B,C) through an arcuate injection groove formed therein. The plug device includes a base member (1) sealingly placed over an open end of the arcuate injection groove (D), a plurality of guide posts (2,3) extending from the base member (1), an equal plurality of rod members (8,9) extending through the guide posts (2,3), and engageable members (10,41) selectively engageable with side walls of the arcuate injection groove (D) by resilient deformation. The engageable members (10,11) are provided at an inner end portion of the guide posts (8,9), or by an external surface (20f Figure 8) of the inner end portions of the guide posts (2,3). The engageable members (10,11) have a width smaller than a width of the arcuate injection groove (D) prior to their deformation and have a larger width after their deformation to provide engagement with the side wall of the groove (D). The injection plug device is used for achieving a method for injecting a concrete repairing agent into the concrete construction. The method includes the steps of forming the arcuate injection groove (D), placing the base member (1) over the open end of the injection groove and engaging the engageable member (10,11) with the groove (D) for fixing the plug device to the concrete construction. <IMAGE></p> |
