临海首条城市快速路高架桥主线提前4个月贯通

Core Viewpoint - The completion of the Linhai Urban Expressway (Southern Section) significantly enhances transportation efficiency, reducing travel time from 20 minutes to under 5 minutes between key points, marking a major infrastructure development in Linhai [1]. Group 1: Project Overview - The Linhai Urban Expressway (Southern Section) project has a total investment of 2.67 billion yuan, making it the largest municipal project in Linhai's construction history [1]. - The project spans approximately 6 kilometers, featuring elevated roads, tunnels, and surface road renovations, with the elevated section measuring about 4 kilometers [2]. Group 2: Technological Innovations - The project is the first in Taizhou's municipal sector to implement a full-chain prefabrication approach for bridge components, utilizing 1,122 prefabricated parts, which has reduced construction time by over 30% and construction waste by approximately 40% [2]. - Advanced technologies such as a steel support axial force servo system have been employed to monitor and adjust support forces in real-time, ensuring stability during construction [2]. Group 3: Environmental and Urban Integration - Non-excavation techniques like pipe jacking and micro-tunneling were used for sewer relocation, allowing for seamless integration of construction with urban operations [3]. - The project includes a fully automated drip irrigation system for landscaping, achieving over 50% water savings, and integrates multiple functions into roadside lamp poles, reducing their number by 30% [3]. Group 4: Impact on Urban Mobility - The expressway alleviates traffic congestion during peak hours and holidays, creating a more efficient transportation network that connects various districts within Linhai [3]. - The project is part of a broader initiative to enhance urban infrastructure, with additional urban renewal projects completed to improve accessibility for residents [3].
