Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to fig. 2, it is a schematic structural diagram of the precise pressure-resistant bent pipe passing through the bridge according to the present invention. The precision pressure-resistant bridge elbow comprises an arc elbow 10 and two elbows 11 respectively connected with two ends of the arc elbow 10, and the precision pressure-resistant bridge elbow further comprises other functional modules, such as connecting threads, buckles and the like, which are well known by those skilled in the art, and will not be described in detail herein.

The outer surface of the corner of the arc-shaped bent pipe 10 and the elbow 11 is provided with a reinforcing rib, and the arc-shaped bent pipe 10 and the two elbows 11 are formed by injection molding at one time. So that no splicing seam is generated between the arc-shaped bent pipe 10 and the elbow 11, the whole structure has high strength, and the pressure bearing device can bear larger pressure. The internal diameter of arc return bend 10 is the same with the internal diameter size of elbow 11, just the internal surface rounding off curved surface of arc return bend 10 can play the cushioning effect when receiving rivers impact, slows down the impact to the pipeline inner wall, can keep the internal diameter size of each position of pipeline the same simultaneously for rivers are not influenced through the flow when arc return bend 10.

The reinforcing ribs comprise a plurality of circumferential reinforcing ribs 12 arranged along the circumferential direction of the arc-shaped bent pipe 10 and the elbow 11, at least two first axial reinforcing ribs 131 arranged along the axial direction of the elbow 11 and at least two second axial reinforcing ribs 132 arranged along the arc-shaped bending direction of the arc-shaped bent pipe 10.
