Description

Underground comprehensive pipe gallery with water storage and preliminary filtration functions

technical field

The invention relates to the technical field of municipal pipe network engineering, in particular to an underground comprehensive pipe gallery with water storage function.

Background technique

The comprehensive pipe corridor is a structure and auxiliary facilities built underground to accommodate two or more types of urban engineering pipelines. Various engineering pipelines such as heating, water supply and drainage are integrated into one body, with special inspection ports, hoisting ports and monitoring systems, and the implementation of unified planning, unified design, unified construction and management is an important infrastructure and lifeline to ensure urban operation.

The underground comprehensive pipe gallery system not only solves the problem of urban traffic congestion, but also greatly facilitates the maintenance and repair of municipal facilities such as electricity, communications, gas, water supply and drainage.

Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". International general term Stormwater Systems Constructed for "Low Impact Development". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. To build a sponge city, there must be a "sponge body". The urban "sponge body" includes not only water systems such as rivers, lakes, ponds, and ponds, but also urban supporting facilities such as green spaces, gardens, and permeable pavements. Rainwater infiltrates, stores, purifies, and reuses rainwater through these "sponge bodies", and finally the remaining part of the runoff is discharged through pipe networks and pumping stations, which can effectively improve the standard of urban drainage systems and reduce the pressure of urban waterlogging.

Combined with the construction of the underground comprehensive pipe gallery, a rainwater compartment is set up in the pipe gallery to store rainwater that cannot be absorbed by the city's "sponge body" and further relieve the pressure of urban waterlogging. Municipal water pressure such as urban greening, road flushing, and dust reduction.
