The outer clay layers of balls 11 of Different Strata or interior clay layers of balls 13 use the clay ball of identical or different specification；So according to thing
Prospect pit result of detection adjusts the specification of the drainage particle of each outer drainage stratum granulosum or interior drainage stratum granulosum and outer clay ball
The specification of layer or the clay ball of interior clay layers of balls so that the structure inside and outside main shaft pipe is more approximate with geologic structure, measurement data
It is more accurate.
Notice plate 15 is set in the upper end of sighting tube 3, is provided with water level gauge 16 on upper lid 14, water level gauge 16 with
The control connection of controlling organization 19 with indication mechanism 18, can complete observation, observation is more in sight chamber in sight chamber 17
It is convenient.
As shown in Figure 2 and Figure 4, for uppermost aquifer sand layer, need not can also be welded on drainage floral tube 7
Sighting tube 3, observed directly in main shaft pipe.Now the top of interior drainage stratum granulosum 12 of the top can not be filled out in main shaft pipe 2
Interior clay layers of balls.Peephole 20 is carried on the lid of main shaft pipe 2.Can be with observed range ground nearest one by peephole 20
SEA LEVEL VARIATION in the aquifer sand layer of layer.So, welding sequence can be effectively reduced, saves the length of sighting tube 3, reduces by a sight
The space that test tube 3 takes, arrange sighting tube 3 more convenient.
The scope of protection of the utility model is not limited solely to above-described embodiment, as long as structure and the utility model underground water
As soon as to be logged well well same or similar more, fall the scope in the utility model protection.
