Problems solved by technology
[0003] At present, most of the highway underwater tunnels and urban road tunnel projects that have been built are not implemented in accordance with the principle of cleaning and diverting sewage. Instead, the structural seepage water and sewage are collected into the same collection pool, and discharged into the urban sewage pipe network or nearby. Rivers and seas, this discharge method does not meet environmental protection requirements
If the sewage is discharged according to the separation of cleaning and sewage, the structural leakage water and waste water are generally collected separately, and two sets of drainage systems for seawater and sewage are used for discharge. This discharge method increases the investment in project construction and operation maintenance costs, and uses sewage pumping and drainage The frequency is low, so the energy saving effect is poor, especially for super-long or super-long subsea tunnels, the cost of two independent drainage systems will increase more significantly

The invention provides a drainage system. The drainage system comprises a seawater pipeline, a sewage pipeline, a seawater pool, a sewage pool and a pump pool, wherein the seawater pipeline is used for conveying seawater; the sewage pipeline is used for conveying sewage, and the sewage pipeline and the seawater pipeline are independently arranged; the seawater pool communicates with the seawater pipeline so that seawater can flow into the seawater pool; the sewage pool communicates with the sewage pipeline so that sewage can flow into the sewage pool; a first gate capable of being closed is arranged between the pump pool and the seawater pool so that the seawater pool can communicate with the pump pool; and a second gate capable of being closed is arranged between the pump pool and the sewage pool so that the sewage can communicate with the pump pool. The invention further provides a subsea tunnel system comprising the drainage system. According to the drainage system, seawater and sewage are separately collected and drained through one pump pool, and the drainage system is environmentally friendly and saves energy.
Description
technical field [0001] The invention relates to the field of underground engineering, in particular to a drainage system and a subsea tunnel system including the drainage system. Background technique [0002] Underwater highway tunnels need to pump structural leakage water, operational flushing water, fire fighting water and other sewage out of the tunnel in a timely manner. Structural seepage water is surrounding rock fissure water, the water quality is close to seawater, and can be directly discharged into the urban rainwater pipe network or nearby waters; operational flushing water and fire fighting water are sewage and should be discharged into the urban sewage pipe network. From the perspective of environmental protection, the drainage system should be discharged in accordance with the principle of clearing and diverting sewage. The water leaking from the structure is seawater, and its chloride ion concentration does not meet the comprehensive sewage discharge standards...
