Abstract
A method of influencing a liquid in ground by forming a liquid circulation in ground comprises a shaft arranged in ground and extending to a desired liquid region, a pump arranged in the shaft for producing a liquid circulation, the pump having a feeding power selected so that in a shaft surrounding a liquid peak located above a normal liquid level is produced.
Claims25
A method of circulating liquid in the ground without causing a drop in the level of such liquid in the ground, comprising:
- forming a shaft in the ground which extends down to a desired region occupied by said liquid, said shaft having liquid permeable portions at a lower and an upper region thereof;
- placing a conduit within said shaft which extends from said lower region of said shaft, upward to a location outside of said shaft;
- said conduit also having an outlet in said upper region of said shaft;
- pumping liquid up through said conduit from said shaft lower region, and pumping part of the liquid out of said outlet into said shaft upper region, and pumping part of said liquid to said location outside of said shaft.
An arrangement for influencing flow of liquid in ground, comprising a shaft arranged in the ground which extends down to a desired region occupied by said liquid, said shaft having liquid permeable portions at a lower and an upper region thereof;
- a transverse wall in said shaft between said lower and upper regions, with a throughgoing passage;
- a conduit in said wall throughgoing passage;
- said conduit extending from said lower region of said shaft, through said wall throughgoing passage, and upward to a location outside of said shaft;
- said conduit also having an outlet in said upper region of said shaft;
- a pump arranged in said conduit for pumping liquid from said lower region of said shaft through said conduit;
- means to allow part of the pumped liquid to exit through said outlet into said shaft upper region, and to allow part of the pumped liquid to be delivered to a treatment device at said location outside of said shaft.

- a pump arranged in said conduit for pumping liquid from said lower region of said shaft through said conduit;
- means to allow part of the pumped liquid to exit through said outlet into said shaft upper region, and to allow part of the pumped liquid to be delivered to a treatment device at said location outside of said shaft;
- means for producing a turbulent water flow impermeably separating said shaft regions from one another.
