Hydro-junction convenient for filtering silt

The hydro-junction comprises a water channel, a plurality of sediment intercepting plates which are evenly distributed are arranged at the bottom in the water channel in the water flowing direction, and a plurality of sediment guide plates are arranged on the upper side of each sediment intercepting plate along the edge of the sediment intercepting plate. The sediment guide plates arranged on the upper sides of every two adjacent sediment intercepting plates are distributed in a staggered mode, the sediment guide plates are obliquely arranged in the direction opposite to the flowing direction of water, a sediment storage cavity is formed between every two adjacent sediment intercepting plates, and a top frame is arranged on the upper side of the water channel; sediment particles in water flow can be conveniently filtered and stored through the sediment intercepting plate, the sediment guide plate and the sediment extraction assembly, the sediment extraction assembly can conveniently extract and guide out the
