It is city underground transportation system with the advantages that its freight volume is big, speed is fast, safe and reliable, punctual, environmental protection, is increasingly becoming many big cities
City solves the primary selection of traffic problems.Shield tunnel is widely used in subway as a kind of safe, efficient construction method
In the work progress in tunnel, more than half in the subway mileage of whole nation planning will use shield construction, but be applied using shield method
Work subway tunnel can produce substantial amounts of discarded slurry.
Currently used method for processing waste slurry is to carry out general separation of solid and liquid at the construction field (site), by discarded slurry point
From into solid portion and liquid portion.The consequence of this simple process method is：1）The landfill of solid portion still needs occupancy
Substantial amounts of farmland, and contain substantial amounts of chemical addition agent in the waste soil filled, will when these additive penetrations are into stratum
Serious pollution can be caused to ground water regime, while need special vehicle to be transported, can also pollute the roadnet in city；
2）Liquid portion is directly discharged into after the sewerage system in city also will by polluted underground water, mud water part subparticle solid
Precipitate in sewer, will slowly block sewer, the flood control, excretion to city damage.3）Due to being simple
Solid-liquid separation treatment, can not separate the premium mud in discarded slurry, this part premium mud is directly discharged into city
City's sewerage system and waste, improve the material cost of mud indirectly.4）The transport of solid portion needs a considerable amount of fortune
Defeated vehicle, adds the cost of constructing tunnel.
When aquifer water-bearing stratum carries out shield-tunneling construction, its discarded slurry water content produced is high, denseness is low, due to discarded slurry
It is too dilute to carry it very difficult to ground, even if its storage also needs to a large amount of mud-settling pits after sending to ground, exist and be difficult to
Storage, the problems such as transport processing is inconvenient, it is therefore desirable to which integrated treatment is carried out to the discarded slurry that aquifer water-bearing stratum shield-tunneling construction produces.
