Well is lifted out after full and empties the rear continuation of lower going-into-well bottom 117 blast well-flushing, until reaching well-flushing requirement.Meausring apparatus can be pulling force
Meter, weight meter etc., the utility model do not limit its type specifically with model, are as long as accurate weighing value can be provided
Can, the utility model does not limit.
In the present embodiment, well-flushing sand pumping device 100 further includes cable, cable have the first connecting pin for being connect with water pump and
For the second connection end being connect with power supply.The setting of cable can be connect with power supply, so as to provide enough continue for water pump
Power.
Refering to Fig. 4, the present embodiment additionally provides a kind of Groundwater Monitoring system 200, and Groundwater Monitoring system 200 includes washing
Well sand pumping device 100 and groundwater monitoring well 101, well-flushing sand pumping device 100 are set in groundwater monitoring well 101.
As a preferred option, groundwater monitoring well 101 has sealing section 121 and fillter section 123, and water pump is set to ground
The sealing section 121 of lower water monitoring well 101.The silt sand of sealing section 121 is less, and the normal operation of water pump is unaffected.Collect sand
Funnel 107 is set to the fillter section 123 of groundwater monitoring well 101.The silt sand of fillter section 123 is more, close shaft bottom 117, herein
It is more preferable to collect silt sand effect.
As a preferred option, fillter section 123 is equipped with the screen pipe 125 for preventing mud from penetrating into.Screen pipe 125 is again
Name " filter pipe " " screen casing ".Most notable " Johnson's pipe " at last.But there are many kinds of screen pipes 125.There is plastic-coated from material point
, stainless steel, low-carbon galvanizing steel, plate other metals etc..Filter pipe is typically considered the heart of well casing, and China gives
Water industry generally use twines the cast iron pipe or steel pipe of silk perforation, and this kind of filter pipe is in underground water easily by chemistry, electrochemistry and thin
The effect of bacterium and be corroded and block, reduce water inlet efficiency and reduce the well service life.It is acute particularly when groundwater corrosivity is strong
Strong destruction can be such that a large amount of grit pours in well, cause silt well and burn out water pump, so that well is scrapped.It is asked to solve this
Topic works out stainless steel filter, fiberglass filter both at home and abroad, and asbestos or pipe of cement twine a filter, and patch sharpens filter etc.
Deng but all because the cost of raw material is high, processing technology is complicated, and capacity of outlet water is low and the factors such as physique structure heaviness make it
Application range is restricted, and cannot get popularity.Thus the selection of filter pipe can be while guaranteed efficiency, and reduction is applied
Work cost, so as to effectively ensure economic benefit.
