The traditional interval wastewater pump room is usually built together with the interval communication channel, and the freezing method + mining method is used for construction. The wastewater pump room foundation pit is set at a depth of 3 to 5 meters below the communication channel. It has high requirements on construction technology and is not suitable for soft geology rich in water and poor stability. The built-in pump room utilizes the roadbed and tunnel structure space under the track, and a long strip sump is set in the center of the roadbed with a drainage pump installed for drainage. Compared with the traditional interval wastewater pump room, the construction is simple, safe and low in construction cost.
