Description

Connector Assembly for Underground Pipeline The present invention relates to a connector assembly for an underground pipeline. Cables for power supply or communication can be installed using an underground burial method. The underground burial method involves installing cables through conduit sections buried underground, and it is known to have significant advantages over the general above-ground installation method in terms of utilizing above-ground space and securing aesthetic appeal. The underground burial work is carried out by securing a corrugated pipe for the conduit to the manhole (pipe adapter) to establish the conduit section, and then connecting the cable through this conduit section. Given that cables are installed underground using this underground burial method, ground subsidence or flooding may occur within the conduit section; therefore, construction stability to address these issues is required. To achieve this, it is important to ensure the stability of the connection points, not only for the connecting parts of the corrugated pipes forming the pipeline sections but especially for the connection points between the pipeline ends and manholes. FIGS. 1 and FIGS. 2 are schematic drawings showing the overall structure of a connector assembly for an underground pipeline according to an embodiment of the present invention. FIGS. 3 to 11 are drawings for explaining the detailed structure and operation of a connector assembly for an underground pipeline according to an embodiment of the present invention. Hereinafter, preferred embodiments of the present invention will be described based on the attached drawings. Embodiments of the present invention are described within the scope in which those with average knowledge in the art can practice the present invention. Therefore, since the embodiments of the present invention can be modified in various different forms, the claims of the present invention are not limited to the embodiments described below. FIGS. 1 and 2 are schematic drawings showing the overall structure of a connector assembly for an underground pipeline according to an embodiment of the present invention, and FIGS. 3 to 11 are drawings for explaining the detailed structure and operation, Referring to FIGS. 1 to 7, a connector assembly for an underground pipeline according to one embodiment of the present invention includes a connection guide tube (10), a connection operating part (20), and a connection tightening part (30). A connector assembly for an underground pipeline according to one embodiment of the present invention is for connecting and fixing the end side of a corrugated pipe (P) for an underground pipeline (L) to a manhole (M) side as shown in FIGS. 1 and 2, and the corrugated pipe (P) for the pipeline has a pipe body structure in which a corrugated portion (P1) is formed on the circumference side.
