For the connection channel and pressure pipe laying

When the channels and rivers, valleys, roads or other channels intersect, for the connection channel and pressure pipe laying. When the intersection height is small, can be buried in the ground, the middle tube body supine, reclined or can be made before  High pressure ball valve  two shafts. Wider use of oblique horizontal; silo flow is not smooth, head loss, suitable for road intersects with the situation. When crossing a large valley height, can be laid in the ground slope, across the water partially  3 way manifolds or through the bridge. The import, export, transition section and tube body 3 parts. Large projects inlet section also sets overhaul tube body, dredging using retaining gates and trash rack and so on.
