Description
Technical field
The present invention relates to ground water engineering technical fields, and in particular to a kind of interior filtering of ground water recharging well plug-in wall
Device can be used in the engineering inverted well of Groundwater Control or underground water pollution control, be to be suitable for underground water to take out filling
The novel built-in filter device of well.
Background technique
In recent years, with the development of social economy and the raising of Public environmental attitude, pass of all circles for groundwater environment
Note degree is also improved.Drainage by well points is commonly used in engineering construction field to guarantee that underground engineering or foundation pit mining position are stablized
The methods of lowering of watertable, meanwhile, to reduce stratum settlement caused by water level decreasing or protection groundwater resources, and usually set
It puts back into and fills the underground reservoir that well point is persistently injected the underground water of extraction outside coverage；In underwater prevention field, extraction-
Recharge processing technique is the classical way generallyd use, can effectively remove the light non-aqueous phase liquids in organic pollutant, the technology
By gang of wells by contaminant water extraction handle, and after water quality reaching standard recharge into stratum, to rinse water-bearing layer, dilution by
Polluted-water, and accelerating ground water circulates, so as to shorten the repair time of underground water.
In pumped well and inverted well, filter is to contact well body structure and aquifer water-bearing stratum, the pass for carrying out underground water filtering
Key composition.Currently, the filter device for taking out, filling well is all made of filter structure on the outside of the borehole wall, according to the property of different water cut layer, filtering
The type of device is divided into skeleton filter, wrapping filter, net covering filtrator or gravel filled filter etc..This kind of filter is in Cheng Jing
Before be set up directly on the outside of well casing or Cheng Jinghou in well week fills out the filtration system that the modes such as gravel are formed.
Shown using a large amount of engineering experiences that pumped well and inverted well carry out underground water pumping filling operation when recharge flow is long-term
When in a high position relatively, easily cause well body that different degrees of silt up occurs.It is especially most commonly seen with inverted well that well body silts phenomenon up,
Even if by groundwater treatment it is up to standard after carry out recharge, throw away easily occur recharge flow occur with the activity duration continue and gradually decrease
Phenomenon.The study found that well body, which silts mainly filter up, occurs local stoppages under biggish flow effect.Due to filter master
It to be made of materials such as nylon wire, steel roll bendings, and in order to ensure filter effect mesh is intensive, hole is smaller between silk, in height
In hardness mineralized water or underground water containing organic sewage, increased because dissolved oxygen content increases with temperature, occur corrosion expansion,
Phenomena such as mineral deposits, electrochemical corrosion, organic matter accumulation, filter gap is caused to block, makes well water outlet or recharge amount
It reduces.
After thering is larger impact, the borehole wall to silt up in view of the normal function and service life of Groundwater confrontation filter
Cleaning and maintenance cost it is excessively high, and existing well-flushing mode (especially chemistry-flushing well method) is likely to result in the secondary of underground water
Pollution, it is necessary to propose a kind of Novel filter device dedicated for ground water recharging well, to reduce the influence of plugged filter,
Ensure the long-term high flow capacity operating of well.
Summary of the invention
