Safety facilities aim to ensure the safety of personnel and vehicles in the tunnel. Well-equipped safety facilities can effectively cope with emergencies in the tunnel. Architectural auxiliary facilities include auxiliary buildings at the entrances and exits of the tunnel, such as control rooms, duty rooms, and equipment rooms. Well-equipped environmental protection facilities can reduce the impact of the tunnel on the surrounding environment. Read More
Rock support: Based on rock mass level, construction environment, and tunnel structure type, adopt support measures such as steel supports, pipe sheds, anchors, shotcrete, etc., to ensure the stability of the tunnel excavation process. Construction process control: Strictly monitor the construction process of excavation, support, lining, etc., to ensure that the construction quality meets the design requirements. Strictly following and implementing the construction specifications for water conservancy tunnel engineering can not only ensure the safety and reliability of the tunnel but also improve the construction quality and efficiency, reduce the impact on the environment, and promote the healthy development of water conservancy tunnel engineering.
