The Cable-Specific Sewage Inspection Well Mold is a composite prefabricated mold designed for underground intersections of cable lines and sewage inspection wells. It enables independent compartmentalization and coordinated layout of cable channels and sewage pipelines within a single well structure. Featuring compartmentalized design, it meets requirements for power/communication isolation, moisture resistance, and rapid maintenance, ideal for urban renewal, road renovations, and utility tunnel projects.
Usage
Prefabricated concrete composite wells for installation, inspection, and maintenance of underground cable lines (power/communication) and sewage pipeline intersections.
Application Fields
Municipal Engineering
Integrated pipeline upgrades at road intersections
Power Infrastructure
Inspection wells for underground cable projects
Smart City
Integrated 5G communication and sewage wells
Industrial Parks
Coordinated cable and sewage networks in factory zones
