Description
Technical field
The present invention relates to a kind of shallow source perched water green construction recycling constructions, belong to building construction technology
Field.
Background technology
In the higher area of level of ground water, during construction project deep pit construction, since water-bearing layer is cut off,
Under differential pressure action, underground water constantly will necessarily enter foundation pit by seepage flow.It such as works without foundation pit Yield rainfall relation, it will foundation pit is caused to soak
Water makes construction condition be deteriorated, and foundation bearing capacity declines, and is also possible to cause quicksand, piping and side under flowing pressure effect
Phenomena such as slope unstability.Therefore, to ensure security of foundation ditch construction, it is necessary to take effective precipitation and drainage measure, pass through to exploit and take out
The underground water in certain area coverage is taken, causes groundwater level in particular range to reduce, i.e. dewatering project.Dewatering project underground
Water has the characteristics that water is big, uninterruptedly exploitation, exploitation period length, mining time and construction project building time registration are high.
Current most of dewatering project underground water are efficiently used without other is directly discharged into municipal pipeline or ground open channel, river
Stream.However, construction project construction itself consumes a large amount of water again, for live drink, fire-fighting, live depositing dust, vehicle rinsing, field
Area's greening, lavatory flushing, construction（Including in structure construction concrete curing, concrete test block maintenance, build by laying bricks or stones plastering,
Decorations are constructed）Deng.Most of these construction waters use municipal water supply at present.These use water, except Drinking Water matter is wanted
Ask higher outer, other are relatively low with water water quality requirement, have in this regard with dewatering project underground water it is very high at right, one
Determine in degree, dewatering project underground water can partly or entirely meet these demands.
