Description

Dirt-cleaning and flow-dividing device for excavation of cavern Technical Field The utility model belongs to the technical field of tunnel construction engineering, and particularly relates to a device for cleaning and diverting waste in a cavity excavation. Background In the construction process of tunnels and underground caverns, two main types of wastewater are often generated, namely tunnel water burst and surrounding rock water seepage, and construction wastewater. The tunnel water-flushing and surrounding rock water seepage are natural water caused by the damage of underground rock and loosening in the process of excavation, and generally belong to pollution-free natural water, and the water quantity is large, but the fluctuation is strong. The construction wastewater is mainly generated by excavating earth and stone in the construction process, contains pollutants such as suspended matters, petroleum and the like, and has poor water quality. In order to reduce the impact of such waste water on the surrounding environment, it must be effectively treated and ensure that the emissions meet environmental standards. However, there are a number of problems with existing wastewater treatment methods, and improvements are needed. At present, the treatment of the waste water of the tunnel chamber generally adopts a method for uniformly treating the mixed and collected water of the tunnel water, surrounding rock water seepage and construction waste water. There are several significant problems with this approach. First, since the water quantity of the water burst and the water penetration fluctuates greatly, the amount of the construction wastewater generated also varies with the progress of the construction, which results in unstable overall treatment amount of the wastewater and large fluctuation. This not only increases the difficulty of wastewater treatment, but also makes it necessary for the treatment equipment to cope with such unstable water amount, resulting in low treatment efficiency. Secondly, the existing wastewater treatment equipment needs to treat a large amount of wastewater, so that the occupied area is large, the land requirement of a construction site is increased, and meanwhile, the equipment is large in scale, so that the construction and operation costs are obviously increased. In addition, existing wastewater treatment systems typically require a longer hydraulic residence time to complete the treatment, which not only places a burden on the equipment, but also increases energy consumption, further reducing treatment efficiency. Finally, because the wastewater treatment capacity is large and the volatility is strong, the existing equipment faces higher load, the failure rate is higher, the equipment is frequently maintained, and the running cost is further increased.
