Adhesive injection apparatus and method for injecting an adhesive or the like cracking of concrete structures

摘要

A sealant injector for filling a crack in a concrete structure comprises an injector(1) and a support portion(2). The injector includes a pressure buffer tube(6), a cylinderical cover(13), a tubular coupler(9) at one end of the pressure buffer tube for connecting the injector to the support portion, coupling members(7,7,) at both ends of the buffer tube, and check values(10,10,) between the buffer tube and the coupling members. The support portion includes a coupler projection(4) and a base member(3) . The coupler projection has a passage therethrough and serve to press one of the check values upon connecting the injector to the support portion to restore the passage of adhesive.
