Further, in an embodiment of the present invention, after the strong electric room module is disposed, the method further includes the following steps: and arranging a special equipment transportation channel. The special equipment transportation channel is arranged in a station hall layer of the rail transit underground station and is used for replacing and transporting the transformer.

In the embodiment of the present invention, the heavy current house module is installed in the enclosed area of the station hall floor, so that the urban land can be fully utilized, the station space can be intensively utilized, the equipment management house layout can be optimized in a large space and modularization manner, the pipeline crossing can be reduced, and the height requirement of the station floor can be reduced. As the strong electricity room module is arranged in the enclosed area of the station hall layer, a special cable channel is needed to lead the cable into the station layer, and a special equipment transportation channel is needed for replacing and transporting the transformer.

Further, in the embodiment of the present invention, after the enclosing region is disposed, the method further includes the following steps: and a weak current room module is arranged in the enclosed area. As shown in fig. 3, the weak current housing module is disposed in the enclosed area, and includes a signal device area, a communication device area, a comprehensive power supply area, and a civil communication area.

Further, in the embodiment of the present invention, after the enclosing region is disposed, the method further includes the following steps: and a management room module and a convenient room module are arranged in the enclosed area.

The passenger flow buffer areas are respectively positioned at the positions closer to the end parts of the rail transit underground station platform layers relative to the escalator starting point along the longitudinal direction (positioned at the outer side of the escalator starting point in the figure 4). The equipment management rooms are respectively located at positions closer to the end portions of the rail transit underground station platform layer in the longitudinal direction relative to the passenger flow buffer area (located outside the passenger flow buffer area in fig. 4). Further specifically, determining the starting points of the escalators at both ends of the platform layer is a prerequisite for arranging the room of the platform layer. After a passenger flow buffer area is reserved at the escalator starting point, equipment management rooms, power substations and the like on the platform can be arranged.

Specifically, in the step, a piston air shaft, a fresh air shaft and an exhaust air shaft are arranged according to corresponding process requirements by combining the layout of the environmental control machine room and the ventilator machine room.

Furthermore, the total length of the station hall layer of the rail transit underground station is the sum of the length of the public area, the length of the environment control room modules respectively positioned at two ends of the public area along the longitudinal direction and the thickness of the outer wall. In the embodiment of the invention, because only the ring control room modules are arranged at two ends of the station hall layer, the pipeline intersection can be reduced.

After the above steps are completed, the overall layout of the station hall layer is completed, and then step S210 is executed: a pay area and a non-pay area of a station hall layer of a rail transit underground station are separated. Specifically, in this step, the public area is divided into two major areas, namely a pay area and a non-pay area, according to the passenger flow characteristics of the station, so that the passenger entering and exiting paths are defined. After separation, passenger service facilities such as security check, ticket vending machine and value adding machine are arranged outside the fee area, and a customer service center is arranged at a position close to the outbound gate.

Finally, after the layout of the station hall layer and the station platform layer of the rail transit underground station is generated, step S30 is executed: and generating the rail transit underground station model according to the generated layout of the station hall layer and the station platform layer of the rail transit underground station.

In summary, in the automatic generation method of the rail transit underground station model provided in the embodiment of the present invention, since the enclosed area is disposed between the two entrances and exits arranged in the longitudinal direction in the process of generating the layout of the station hall layer and the station platform layer of the rail transit underground station, and the heavy electricity room module is disposed in the enclosed area, intensive use of urban land and full utilization of underground space resources are realized to realize sustainable development, and the defect that the land in the area cannot be effectively utilized in the past is solved.
