The construction of hydraulic tunnels under unfavorable special bad geological conditions is difficult, as accidents such as collapse, roof fall, water inrush, mud inrush, etc. may occur and cause serious consequences, with high construction risk. The use of a reasonable construction scheme can reduce the probability of accidents and ensure the safety of construction. Therefore, the construction technology of the section with water inrush and collapse has been researched. First, the tunnel is dredged and the tunnel face is closed, and the construction is carried out using big pipe shed, supplemented with pre-grouting small pipe, followed by the second concrete in time to ensure the construction Safety.
