The invention belongs to the technology field of urban underground pipe gallery engineering, and discloses an integrated drainage system of an urban underground pipe gallery. The system comprises a comprehensive cabin, a gas cabin and other cabin, a comprehensive cabin water collecting pit, a gas cabin water collecting pit and an other cabin water collecting pit, wherein the bottom of the comprehensive cabin water collecting pit communicates with the bottom of the other cabin water collecting pit correspondingly, a drainage pump and a liquid level switch are arranged in the comprehensive cabinwater collecting pit, a water outlet end of the drainage pump is connected with a drainage pipe, and an outlet of the drainage pipe communicates with a rainwater inspection well; and the comprehensive cabin is provided with a PLC control cabinet, the liquid level switch comprises a water seal liquid level switch, a pump stopping water level switch, a pump starting water level switch and an alarmwater level switch, wherein the water seal liquid level switch, the pump stopping water level switch, the pump starting water level switch and the alarm water level switch are connected with the PLC control cabinet through a liquid level control line. The integrated drainage system of the urban underground pipe gallery has the advantages that the drainage pump is installed in the comprehensive cabin water collecting pit, the other cabin water collecting pit does not need to be additionally provided with the drainage pump, water in the other cabin is concentrated in the comprehensive cabin water collecting pit to be discharged together, so that the operation is convenient, overhaul is convenient, and investment is saved.
Description
technical field [0001] The invention belongs to the technical field of urban underground comprehensive pipe gallery engineering, and belongs to a sump drainage pump sharing system for each cabin (except the gas cabin) of the underground comprehensive pipe gallery, in particular to an integrated drainage system for the urban underground comprehensive pipe gallery. Background technique [0002] The comprehensive pipe gallery is a structure and ancillary facilities built underground to accommodate two or more types of urban engineering pipelines. In order to meet the requirements of eliminating structural leakage water in the comprehensive pipe gallery and venting water from pipeline maintenance, an organized drainage system is required in the comprehensive pipe gallery. The existing drainage method of the integrated pipe gallery is: one-sided or two-sided drainage open ditches are set in each fire compartment of each cabin, and a sump and a drainage system that can be manually...
