Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated in figures 3-6, the utility model pressure pipeline steel lining section discharge structure, along water (flow) direction be transition 11, on
Flat section 12, upper curved section 13, vertical shaft section 14, lower horizontal section 15, lower flat section 16, Taper Pipe section 17 and changeover portion 18, wherein transition 11
Upstream side is intake tower 6, and the downstream of changeover portion 18 is factory building upstream abutment wall 7.Flat section 16, Taper Pipe section 17 and changeover portion 18 are pressed down
The inwall of hydraulic piping is provided with plate-steel liner 2, is steel lining section.Osculum 21, osculum 21 are set down in the plate-steel liner 2 of flat section 16
Place's connection drainpipe 3, downstream direction arrangement of the drainpipe 3 along pressure pipeline.Because the bottom of lower flat section 16 is again in whole steel lining
The position of section is minimum, so drainpipe 3 can drain the ponding of pressure pipeline bottom.
