The invention belongs to the technical field of rainwater reutilization and waterproof comprehensive 
pipe gallery construction and particularly relates to a waterproof comprehensive 
pipe gallery structure of an ecological 
system of a 
sponge city. The structure is used as a drainage device in heavy rain and applied for 
irrigation after raining, so that the content of heavy 
metal ions in rainwater is reduced, the influence on underground water is reduced, urban waterlogging is alleviated, the functions of the 
sponge city are realized, and ground 
precipitation is filtered and drained. Water in the soil around the comprehensive 
pipe gallery is collected and circulated, damaged caused to a gallery body by water accumulation at the periphery of the gallery body and 
water seepage, 
water leakage and the like in the gallery body, the service life of the gallery body is indirectly prolonged, and self-circulation of underground water in the soil can be formed; the waterproof and anti-
corrosion construction problems of existing underground pipe galleries are solved, the maintenance cost of the underground pipe galleries in the later use period is reduced, and the service life of the underground pipe galleries is prevented from being shortened by 
water leakage and 
corrosion. In this way, the service life is prolonged, the problems of water acquirement, water utilization and the like of thecomprehensive pipe gallery are effectively solved, and the structure has high practicability and applicability.
