The present invention relates to a tube insertion type-waterproof device for a pipe conduit, and more specifically, to a new technology to simply waterproof the pipe conduit by corresponding to a change in the size of the pipe conduit embedded underground and to easily install an additional cable. A rubber element of a conventionally disclosed waterproof device of a pipe conduit is formed as a separate single component such that the handling of the rubber element is difficult. Moreover, much work time is taken to install rubber elements one by one, and a fine gap formed after the installation cannot be completely blocked. Furthermore, there is no coupling force between the rubber elements such that rigid integrity cannot be maintained. In addition, the rubber elements are pushed into the pipe conduit to cause a movement, thereby reducing constructability. According to the present invention, to solve the described problems, a tube package including a plurality of filling tubes whose outer circumferential surfaces in the longitudinal direction are integrally formed, is inserted into a space between an interior surface of the pipe conduit and a cable to be installed. The filling tubes of the tube package are detached from the tube package one by one to be installed to block a fine gap between the tube package and the cable. |
