Patent ID: 7434615

Claim:
An apparatus for preventing pollution of a groundwater borehole comprising: a first intake pipe for forming a groundwater borehole; a second intake pipe fluid-communicatively coupled to the first intake pipe and closing an opening of the first intake pipe; an underwater motor pump located inside the first intake pipe for discharging groundwater from the intake pipes to the outside; an induction pipe connector mounted inside the second intake pipe and connected with the motor pump for supporting the motor pump, the induction pipe connector having a discharge path for discharging the groundwater pumped up by the motor pump to the outside of a side of the second intake pipe; fixing means respectively mounted on a side surface of the induction connector and a side surface of the second intake pipe directed to each other for supporting the induction pipe connector to the second intake pipe in balance; and a pressure controlling part mounted on the outer circumferences of the intake pipes in such a manner as to communicate with the second intake pipe via a portion adjacent to the induction pipe connector for uniformly controlling the inside pressure of the intake pipes.
