Background
The rail transit construction promotes the development of urban economy, solves the problem of urban traffic congestion, improves the travel conditions of people, but also brings a series of environmental and safety problems, wherein the muck treatment is the most prominent problem in the subway construction process.
The subway is generally divided into stations and interval construction, and the interval construction generally adopts a shield method. Most of shield muck is fine particles, the water content is higher, and the harmfulness of muck generated by drilling and blasting and other mechanical excavation methods is larger.
Firstly, various environmental and safety problems often occur in the process of transporting the residue soil, such as environmental problems of dust raising, leakage, stealing, pulling, disordering and the like, and safety problems of overspeed, overload and the like.
Secondly, with the development of large-scale construction, the muck landfill site is seriously insufficient. Taking the example of the long sand, the total storage capacity of the existing absorption site is only about 800 ten thousand cubic meters, while the amount of the slag which has been treated in 2015 of the long sand city is 1800 ten thousand cubic meters, and the storage capacity is increased at a speed of 15% every year. Only when the Changsha No. 2 line is constructed, the amount of the generated muck is 400 ten thousand cubic meters.
Thirdly, the shield muck contains a large amount of foaming agent, and if the foaming agent is not treated, the surrounding water and soil environment is easily polluted.
Finally, the shield muck has high water content and poor stability, and is easy to develop into potential safety hazard by direct filling. 12 and 20 days 2015, 73 people die due to a landslide accident in the red depression slag receiving field in the Shenzhen Guangming new region, 4 people are unclear, 17 people are injured, 33 buildings are damaged and buried, and the accident causes direct economic loss of 8.81 hundred million yuan.
At present, the dehydration treatment of the shield muck becomes a research hotspot, and research shows that the shield muck can save treatment cost by at least 44% after the dehydration treatment.
The dewatered residue soil can save a stacking and filling site and can be even recycled as roadbed filling.
The original state slag is pasty and can not be directly filled, only the pit and the cave can be found for filling, the water content is reduced to below 25 percent, and the slag can be filled to a height of several meters without landslide; if the water content is reduced to the optimal water content, the roadbed can be pressed. And if the water content is lower than the optimal water content to a certain degree, the residue soil has screenability. For residue soil with the mud content of more than 80%, the screening value is not great; the residue soil with the particle size of more than 2mm and more than 50 percent has larger screening value, and the sand and stone obtained by screening can be used for preparing low-strength cement products.
In conclusion, the dehydration treatment of the muck is the most important link for treating the muck.
At present, many types of dehydration treatment equipment are developed in China, such as plate-and-frame filter presses, belt filter presses, horizontal screw centrifuges, vacuum belt filter presses, rotary drum dryers, infrared dryers and the like, and the treatment of the muck by using the equipment has certain effect but also has many problems:
