The invention discloses a pipeline embedding device for water conservancy projects, and relates to the technical field of pipeline embedding devices. A winch is fixedly installed at the bottom of a threaded seat, a support rod is fixedly connected between two groups of connecting steel blocks, the bottom ends of the two groups of connecting steel blocks are fixedly equipped with clamping devices,the left end of a second lead screw penetrates through a fixing seat to be fixedly connected to a second motor, an inner cavity of the fixing seat is provided with a guide seat connected to the outerwall of the second lead screw in a sleeving manner, an object containing plate is fixedly arranged between fixing frames, the top of the object containing plate is evenly and fixedly provided with limiting rings, two groups of guide plates are fixedly arranged on the right side of the top of a base, protection plates are fixedly assembled on the side walls between the two groups of guide plates, and a discharging channel is arranged between the two groups of protection plates. Automatic clamping and laying of pipelines are realized, pipeline protection can be realized, the needs of continuouspipeline placing and laying are met, and the pipeline laying efficiency is improved.
