Cast-in-place concrete wall water supply pipe groove pre-embedding device

The utility model provides a cast-in-place concrete wall water supply pipe groove pre-burying device, which relates to the technical field of building construction, and comprises two groups of template units, a connecting bridge and an adjustable pre-burying assembly, the two groups of template units are fixedly connected through the connecting bridge and are symmetrically arranged on the two sides of the connecting bridge; a worker rotates and adjusts the adjusting bolt according to the depth of the water supply pipe groove in advance, fine adjustment of the embedded square pipe in the strip-shaped cavity is achieved, at the moment, the protruding height of the embedded square pipe is the depth of the water supply pipe groove formed subsequently, then the embedded device is assembled with other adjacent formworks, and then one-time pouring forming of the water supply pipe groove is achieved. Later secondary processing is not needed, and the attractiveness of the formed wall is guaranteed; the embedded device
