高海拔高寒地区隧道冬季施工技术研究

Research on Winter Construction Technology of Tunnels in High Altitude and Cold Regions

本文主要介绍了在国道317线雀儿山隧道施工中,由于该隧道地处于高海拔低纬度地带,冬季漫长气候恶劣,对施工人员健康和施工质量均提出了严峻考验。为保证施工人员的身心健康和工程质量,项目部对此制定了详细的供暖保暖方案,从作业区和混凝土施工等多个方面进行温度控制。通过一系列举措,不但确保了施工生产的稳步推进,而且工程质量也得到有效保障。该高海拔高寒地区隧道保暖控温等技术也为后续类似施工提供了借鉴和参考。

This article mainly introduces the construction of the Queershan Tunnel on National Highway 317.Due to the high altitude and low latitude area of the tunnel,the long winter and harsh climate pose a severe test for the health and construction quality of the construction personnel.In order to ensure the physical and mental health of construction personnel and the quality of the project,the project department has formulated a detailed heating and insulation plan,which controls temperature from multiple aspects such as the operating area and concrete construction.Through a series of measures,not only has the steady progress of construction production been ensured,but the engineering quality has also been effectively guaranteed.The technologies such as thermal insulation and temperature control for tunnels in high-altitude and cold regions also provide reference for similar construction in the future.
