Description

Technical Field

[0001] The invention relates to the field of computer-aided design of construction engineering, and in particular to an automatic design method for a rail transit line, a section plan connection channel and a pump room. Background Art

[0002] A connecting passage is a horizontal passage between two subway tunnels, which plays a role in the safe evacuation of passengers, tunnel drainage, fire prevention, and fire fighting. Article 28.2.4 of my country's "Metro Design Code" GB50157-2013 stipulates that two single-track section tunnels should have a connecting passage, and the distance between two adjacent connecting passages should not be greater than 600m.

[0003] Article 14.3.4 of my country's "Metro Design Code" GB50157-2013 stipulates that the main drainage pump station in the section should be located at the lowest point of the actual slope of the line. When there are more than two lowest points in the longitudinal section of the section line, the main drainage pump station should be set up at each lowest point.

[0004] Generally, the wastewater pump room is built together with the communication channel, that is, the wastewater pump room as well as pipes and pipe wells for wastewater pumping and personnel maintenance are set up in the communication channel, which is conducive to subsequent operation and maintenance management, and any faults can be handled in time.

[0005] At present, designers in the rail transit industry mainly use the following methods when designing communication passages and wastewater pump rooms in section plans.

[0006] This includes manually reading the lowest point mileage of the section line in the AutoCAD line plan design and positioning it in the section plan. Manually measuring the distance between the lowest point of the line and the start and end points of the section, manually calculating and allocating the number and location of the communication channels and wastewater pump houses, and verifying whether they meet the relevant specifications. Manually drawing the communication channels and wastewater pump houses in the section plan, and marking the name, the mileage of the center line of the communication channel based on the left and right lines of the line, the coordinates of the intersection of the center line of the communication channel with the left and right lines of the line, and the line spacing between the left and right lines of the line at the center line of the communication channel.

[0007] The current method used by designers to design the interval plane communication channel and the sewage pump room has the following shortcomings:

[0008] The existing method requires manual reading of the lowest point mileage of the section line in the line plan design and positioning in the section plan. Manually measure the distance between the lowest point of the line and the start and end points of the section, and manually calculate and allocate the number and location of the communication channels and wastewater pump rooms.

[0009] The existing method requires manual drawing of the connecting channel and the sewage pump room in the section plan, and marking the name, the mileage of the center line of the connecting channel based on the left line and the right line of the line, the coordinates of the intersection of the center line of the connecting channel with the left line and the right line of the line, and the line spacing between the left line and the right line of the line at the position of the center line of the connecting channel.
