摘要:
高宣圩部分堤段护坡及护岸损坏严重,无法满足行洪和正常运行要求。根据堤防现状、河道水流条件和自然地理状况,并参考附近类似工程,对堤防外坡、内坡和护岸进行防护加固设计。其中,堤段外护坡采用六边形C25混凝土预制块,上端设混凝土封顶,下端设混凝土脚槽,斜坡平台交接处设混凝土格埂,以满足防护稳定和水利血防的要求; 外坡硬质护坡以上至堤肩以及堤内坡均采用草皮护坡。局部堤段外坡底部采用0.8～1.0m厚和20m宽的抛石护岸,抛石固脚向上抛至设计枯水位以上0.5m,与预制块护坡脚槽相衔接。护坡和护岸加固设计方案满足当地防洪达标要求,亦可供平原地区类似堤防工程护坡和护岸加固时参考。
Abstract:
Some of the slope protection and revetment in Gaoxuan Polder were seriously damaged and could not meet the requirements of flood discharge and normal operation. According to the current situation of embankment, river flow conditions and natural geographical conditions, and with reference to similar projects nearby, the design of protection and reinforcement for the outer slope, inner slope and revetment of the embankment is carried out. Among them, the outer slope protection uses hexagonal C25 concrete precast block, the upper end is set with concrete top, the lower end is set with concrete foot groove, the junction of slope platform is set with concrete ridge, in order to meet the requirements of protection stability and water conservancy schistosomiasis control; Turf is used for slope protection from the hard outer slope to the shoulder and the inner slope. At the bottom of the external slope of the local embankment section, a riprap revetment with a thickness of 0.8～1.0 m and a width of 20m is adopted, and the riprap anchor is thrown upward to 0.5m above the design low water level, which is connected with the prefabricated slope protection foot groove. The slope protection and revetment reinforcement design can meet the local flood control standards, and can also be used as a reference for the slope protection and revetment reinforcement of similar embankment projects in plain areas.
