在广西上思县念伦水库溢洪道除险加固设计中,对原破损的溢流面进行凿毛,另铺一层混凝土作底板,让新老混凝土用锚筋连接,联合受力,同时在原溢流面上凿槽铺设纵横塑料透水盲管,以降低底板扬压力。设计较大程度地降低了工程造价,满足了溢洪道的泄洪功能要求,实践证明是行之有效的。 In Shangsi County, Guangxi Nalun reservoir spillway reinforcement design, the original damaged spill surface chiseling, and the other shop for a layer of concrete for the floor, so that the old and new concrete anchor wire connection, the joint force, while the original overflow Flowing surface of vertical and horizontal laying of plastic blind water pipe to reduce the pressure on the floor. The design has reduced the project cost to a great extent and satisfied the spillway flood discharge function requirements, which proved to be effective.
