Description
Technical field
The present invention relates to monitoring well construction applications, in particular to a kind of continuous dedicated sealing of binary channels groundwater monitoring well casing
Plug.
Background technique
Since 2014, the whole nation creates about 5000 mouthfuls of groundwater monitoring well every year.As government, employer's organization etc. are to underground
The raising that water monitoring requires, the monitoring well shaft building mode of traditional individual well single layer can gradually be replaced by a bite multilayer monitoring well.By
The professional standard " the continuous multichannel hierarchical monitor specification of groundwater monitoring well " that China Geological Survey Bureau organizes and implements is being drafted,
After professional standard publication, the inevitable construction work for greatly pushing multistage monitoring well.
In recent years, by territory portion the office of tune entrusts, and China Geological Survey Hydrogeology Environment Geological Survey Center undertakes
The R&D and promotion work of national groundwater monitoring well building technology and groundwater monitoring technology, has now been developed a variety of
The multistage monitoring well tubing of type, including continuous binary channels monitoring well casing, continuous triple channel monitoring well casing, the monitoring of continuous four-way
Well casing, continuous six channel monitorings well casing, continuous seven channel monitorings well casing.Using continuous multi-channel testing well casing, the country has been built
At continuous more than 70 eye of multi-channel testing well, continuous binary channels monitoring well tubing has been succeeded in developing, and is widely used, existing to stop
The eventful stopper of water plug or resilient plug carry out sealing, and sealing resistance to pressure is low, cannot use for a long time, and water-stagnating effect is poor, but specially
It is at present still blank with mating filler block.
Summary of the invention
The invention aims to solve in above-mentioned existing background technique, the eventful stopper of existing filler block or elasticity are filled in
The problems such as whereabouts water, sealing resistance to pressure is low, cannot use for a long time, and water-stagnating effect is poor, lacks special-purpose assorted filler block, and provide
A kind of continuous dedicated filler block of binary channels groundwater monitoring well casing.
A kind of continuous dedicated filler block of binary channels groundwater monitoring well casing, be by overhead gage, lower baffle plate, watertight rubber plug and
Bolt composition, overhead gage and lower baffle plate are separately positioned on the upper/lower terminal of watertight rubber plug, bolt be each passed through overhead gage, under
Baffle and watertight rubber plug, and overhead gage, lower baffle plate and watertight rubber plug are set together;
There is first through hole on the overhead gage, there is internal thread hole on lower baffle plate, watertight rubber has second to lead to beyond the Great Wall
Hole;The first through hole, internal thread hole and the second through-hole difference are concentric;
The overhead gage and lower baffle plate material are engineering plastics, and watertight rubber plug material is environment-friendly type hard rubber;
The outer diameter 70mm of the watertight rubber plug, the high 45mm of watertight rubber plug, the high 22.5mm of overhead gage, lower baffle plate are high
22.5mm。
The working principle of the invention and process:
In underground water pollution monitoring drilling, tripping in binary channels monitors well casing, and binary channels, which monitors well casing, has 2 independences logical
Road, 2 autonomous channels are provided with partition, carry out independent monitoring to 2 underground water pollution layers;
To ensure hierarchical monitor effect, first is that corresponding to pollution layer monitor layer position in binary channels monitoring well casing, specific purpose tool is used
Monitoring window is opened on binary channels monitoring well casing, it is therefore an objective to so that the monitoring channel of binary channels monitoring well casing and monitored layer position phase
It corresponds to, misplace, the underground water of target zone is allowed to flow into binary channels monitoring well casing;Second is that inside binary channels monitoring well casing, benefit
With this filler block, layering sealing is carried out, it is therefore an objective to cut off the contact channel between pollution layer position, prevent the pollutant of purpose of horizon
Mutually gang up;
The corresponding monitoring purpose of horizon of binary channels monitoring well casing is calculated, tube wall is cut open, makes window of receiving water, pass through window of intaking
This filler block is put into binary channels monitoring well casing at mouthful, constantly screws the bolt on filler block with screwdriver, bolt respectively with
Overhead gage and lower baffle plate match, and squeeze watertight rubber plug, are radially expanded watertight rubber plug, watertight rubber plug is contacted and squeezed
Pressure, sealing binary channels monitoring well tube wall, binary channels is monitored and is pumped into clear water in well casing, examines watertight rubber plug water-stagnating effect,
Then by the binary channels made monitoring well casing (plug containing this watertight rubber) tripping in drilling, monitoring well construction work is completed.
Beneficial effects of the present invention:
Structure of the invention is safe and reliable, easy to use, and by mechanical compression rubber stopper sealing, water-stagnating effect is reliable, can root
It is needed according to sealing pressure resistance, the length of watertight rubber plug, or series connection watertight rubber plug is customized, dedicated for the monitoring of continuous binary channels
Well construction, the critical component of continuous binary channels monitoring well, lacks, and is unable to complete monitoring well construction, carries out packing target zone in pipe
With non-object layer underground water, long service life, environmentally friendly not polluted underground water.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Schematic diagram when Fig. 2 is work of the invention.
Watertight rubber stopper becomes schematic diagram when Fig. 3 is work of the invention.
Specific embodiment
It please refers to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of continuous dedicated filler block of binary channels groundwater monitoring well casing, is by upper
