Dewatering construction method applicable to tunnel in water-rich quicksand stratum
The invention belongs to the technical field of dewatering construction, and particularly relates to a dewatering construction method applicable to a tunnel in a water-rich quicksand stratum. The problem that the stability of surrounding rocks becomes poor due to water and sand gushing in the tunnel in the quicksand stratum, and the tunnel cannot be constructed normally is solved. The dewatering construction method is suitable for adopting a three-step method or a CRD method to excavate the tunnel, and two dewatering measures of proactive vacuum dewatering and gravity type deep well dewatering are taken on a middle step. The problem of water and sand gushing is effectively solved, the tunnel is easy to excavate and support, the security coefficient of construction is large, construction quality is effectively ensured, the dewatering construction method is suitable for mountain ridge deep tunnels of railways and roads under soft complicated geological conditions of a water seepage sand bed, a cobble gravel bed and the like with the low silt content, and dewatering and water stopping construction of building and civil engineering foundation engineering and underground tunnel projects of municipal administration, an electric power department and a water conservancy department can use the method for reference.
