The invention discloses pre-buried waste landfill
leachate treatment equipment which comprises a liquid pumping vehicle and a liquid collecting
assembly pre-buried underground, a liquid pumping
drill pipe is installed on the liquid pumping vehicle, the bottom end of the liquid pumping
drill pipe is connected with a drilling head through a universal hinge, and the hinge position is sleeved with a sleeve capable of axially moving; the liquid collecting
assembly comprises a liquid collecting box, a guide ball connected through a spherical hinge and a sleeve limiting
assembly arranged in a guide channel of the guide ball. The drilling head sequentially penetrates through the
butt joint section and the guide channel to enter the communication section, the sleeve limiting assembly limits the sleeve to continue to move downwards, and coaxial constraint of the drilling head and the liquid pumping drilling
pipe is relieved. Through cooperation of preliminary guiding of the guiding ball, triggering limiting of the sleeve limiting assembly and deflection compensation of universal hinging, the technical problems that a traditional percolate collecting facility is high in capital construction cost, inflexible in arrangement, poor in
butt joint precision and prone to leakage are solved, and rapid, self-adaptive and sealed extraction under the complex working condition is achieved.
