The utility model provides a technical scheme that its technical problem adopted as follows:

The utility model discloses a take underground rainwater to collect underground pipe gallery structure of function, including burying underground the piping lane major structure in underground pit underground, the inherent horizontal both sides of piping lane major structure set up rainwater box culvert, characterized by: the top of the pipe gallery main structure is provided with a fine aggregate concrete slope, a structural waterproof layer surrounding the top surface of the fine aggregate concrete slope and the outer wall and the bottom wall of the pipe gallery main structure is arranged, a top permeable layer is arranged on the top structural waterproof layer, and gallery top water outlet pipes communicated with the top permeable layer and the rainwater box culvert are arranged at intervals along the length direction of the pipe gallery main structure; plain concrete layer is pour on the bottom surface concrete bed course of underground structure and the domatic both sides, sets up domatic permeable bed on the plain concrete layer of both sides to set up the corridor side outlet pipe that communicates domatic permeable bed, rainwater box culvert along piping lane major structure length direction interval.

The utility model has the advantages of environmental protection and low construction cost; underground rainwater in the backfill soil at the top and the periphery of the pipe gallery is effectively collected, converged into the rainwater box culvert and discharged, and the soil environment at the top and the side of the pipe gallery is improved; the waterproof effect of the main structure of the pipe gallery is enhanced by matching with a structural waterproof layer, and the durability of the structure is ensured; possess the collection function of earth's surface rainwater and the peripheral secret rainwater of piping lane simultaneously, can realize the reutilization of rainwater, improve the utilization ratio of earth's surface precipitation, be the effective measure who founds the sponge city.
