The underground drainage pipeline for water conservancy construction comprises a plurality of cement pipes which are matched in an end-to-end inserting mode, first clamping sleeves are arranged at the head ends of the cement pipes, step grooves are formed between the first clamping sleeves and the end portions of the cement pipes, and the step grooves are used for being in butt joint with the tail ends of the adjacent cement pipes. The tail end of the cement pipe is sleeved with a movable second clamping sleeve, and the butt joint side of the first clamping sleeve and the butt joint side of the second clamping sleeve are sealed through sealant. Adjacent pipelines are in butt joint in a plug-in mode, butt joint is stable, meanwhile, the contact face is enlarged, the water flow permeation path is improved, the space between the installed second clamping sleeve and the cement pipe and the space between the installed second clamping sleeve and the first clamping sleeve are filled with sealant, and the sealing per
