Advanced radial water lowering channel system and advanced radial water lowering method
The invention relates to the technical field of tunnel construction, in particular to an advanced radial water lowering channel system and an advanced radial water lowering method. The advanced radial water lowering channel system comprises a horizontal water lowering channel, a communication ring pipe, a vacuum filter pipe, an evacuated water lowering main pipe and a vacuum water lowering pump, the horizontal water lowering channel is arranged in a tunnel surrounding rock to be excavated, the vacuum filter pipe is inserted into the tunnel surrounding rock outside the horizontal water lowering channel, water in the tunnel surrounding rock enters the vacuum filter pipe under the action of the vacuum water lowering pump, enters the communication ring pipe through a joint, enters the evacuated water lowering main pipe through a communication short pipe and finally is drained through the vacuum water lowering pump, water lowering effects are obvious, field implementation is easy, characteristics of weak surrounding rocks are improved, saturated water level is reduced below an excavation line, and excavation of a subsequent tunnel is ensured.
