穿塬越渭送“甘露”

Core Viewpoint - The successful completion of the northern line of the Yinhang Jihui Phase II project marks a significant milestone in addressing water scarcity in the Weibei region, with the project expected to provide reliable water supply from the Han River to various areas in Shaanxi Province by 2026 [2][3][11]. Group 1: Project Overview - The northern line of the Yinhang Jihui Phase II project spans 89.54 kilometers, connecting the Huangchigou water distribution hub in the south to the Fen Shui Kou in the north [6][8]. - Once operational, the project will supply nearly 100 million cubic meters of water annually to the main urban area of Xi'an, benefiting approximately 2 million residents [11]. Group 2: Technical Challenges and Solutions - The construction faced significant challenges, including the need to tunnel through soft soil conditions and the requirement to safely navigate under critical infrastructure [14][17]. - Innovative construction techniques, such as combining shield tunneling with conventional excavation, were employed to overcome these challenges, ensuring minimal disruption to surface structures [16][18]. Group 3: Environmental and Economic Impact - The project emphasizes ecological sustainability, with measures in place to prevent soil erosion and promote green construction practices [22]. - The introduction of Han River water is expected to stabilize water quality and reduce production costs for local industries, such as the Shaanxi Rainbow Optoelectronics Technology Company, which relies heavily on water for its operations [19][21].
