Abstract
Abstract A method of tapping groundwater and an apparatus therefor are disclosed. A probe is driven to a water bearing stratum to determine the depth thereof. Then a riser tube is driven to the thus determined depth and a riser conduit with a foot valve is lowered into the riser tube, whereupon a suction-producing device, (e.g. pump) is connected to the upper end of the conduit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A method of sinking a shallow well and installing a pump therein, comprising the steps of sinking a probe into the ground, said probe being formed with means for accumulating soil; periodically extracting the probe from ground during its progressive sinking for examining successive soil samples until a water bearing stratum has been located and its depth determined; thereafter driving a riser tube into the ground to the previously determined depth; installing in the riser tube a water conveying conduit having a foot valve; and installing in the region of an upper end of the riser tube suction means which communicate with the conduit to aspirate water through the same.
Claim 2
Independent Claim
110 words
A method of sinking a shallow well and installing a pump therein, comprising the steps of sinking a probe into the ground, said probe being formed with means for accumulating soil; periodically extracting the probe from ground during its progressive sinking for examining successive soil samples until a water bearing stratum has been located and its depth determined; thereafter driving a riser tube into the ground to the previously determined depth; installing in the riser tube a water conveying conduit having a foot valve; and installing in the region of an upper end of the riser tube suction means which communicate with the conduit to aspirate water through the same.
Claim 3
Dependent Claim
26 words
A method as defined in claim 1; wherein the step of driving comprises forcibly inserting the riser tube into the hole previously occupied by the probe.
Claim 4
Dependent Claim
37 words
A method as defined in claim 1, wherein the step of driving comprises subjecting a trailing end of the riser tube to axially acting impacts and causing turning of the riser tube about the longitudinal axis thereof.
Claim 5
Dependent Claim
112 words
In a combination for sinking a shallow well, an apparatus comprising a tubular probe composed of a plurality of longitudinally connectable sections and having a leading end adapted to be driven downwardly into the ground; and a guide rod movably mounted on said probe for movement therewith into the ground and displaceable relative to said probe for movement relative thereof, said rod having a portion located in the region of said leading end and provided with at least one soil-accumulating recess so that soil accumulated in said recess can be inspected for moisture traces when the rod is displaced upwardly and relatively to said probe which is meanwhile stationary in the ground.
Claim 6
Dependent Claim
112 words

Claim 7
Dependent Claim
25 words
In a combination as defined in claim 4; and further comprising means for extracting said probe from the ground upon completion of the ground inspection.
