| titleOfInvention | Extension type drain hole capable of reducing lateral diffusion of water flow |
| abstract | The invention relates to the technical field of drainage building design, in particular to an extension type drainage hole capable of reducing transverse diffusion of water flow. Including along the import section, anterior segment, middle section, back end and the export section that the rivers direction distributes in proper order, the hole body level in import section, anterior segment, middle section, the hole body downward sloping of back end and export section, the export section radially is equipped with export section top, export section bottom and export section butterfly lateral part along the pore wall, export section top is apart from the central length of cross section and is short in export section bottom, export section butterfly lateral part apart from the central length of cross section, the bottom of export section upwarps at the terminal department. The horizontal diffusion of the nappe is reduced and part of horizontal impact force is consumed at the same time at the outlet through the horizontal butterfly and arc composite body design, so that the scouring of the nappe to the side wall of the outlet is reduced, and the structural stability of the outlet of the drain hole is effectively protected. |
