Abstract:With the rapid economic development of our country, urban land resources are becoming increasingly scarce, which has elevated the status of comprehensive utility tunnels in urban planning. However, the construction practice history of our country's comprehensive utility tunnels is relatively short, and many issues still exist. Based on this, the article introduces the origin and development of comprehensive utility tunnels, analyzes the special requirements of electrical and automatic control engineering in utility tunnel projects; subsequently, it examines the key design points of electrical and automatic control engineering in utility tunnel projects from aspects such as drawing preparation, power supply load calculation, integration of alarm and monitoring systems, design of power distribution and supply solutions, design of grounding systems, lighting system design, safety prevention system design, computer system design, and communication system design.
