Construction process of ultra-large inclined-wall emergency accident pool
The invention discloses a construction process of an ultra-large inclined-wall emergency accident pool. The construction process comprises the following steps: firstly, cutting off a river channel, damming and draining, and dredging the river channel; then the soft foundation is solidified, deep mixing piles are constructed, and then a bidirectional geogrid, lower-layer geotechnical cloth, a water filtering pipe, a gravel layer, middle-layer geotechnical cloth, an HDPE impermeable film, upper-layer geotechnical cloth and a cushion layer are sequentially laid on the soft foundation; during pouring, the emergency accident pool body is divided into a plurality of sections (small pools), construction is carried out according to plates, concrete pouring and maintenance of all the plates are completed above a cushion layer, and finally the inverted trapezoidal emergency accident pool body is formed. The construction method disclosed by the invention is scientific, and achieves remarkable effects in the aspects of construction efficiency and material utilization; meanwhile, the accident pool construction mode of selecting the'maximum accident method 'depending on the riverbed has wide application prospects and popularization values under the conditions of land resource shortage and chemical industry clustering.
本发明公开了一种超大型斜壁应急事故池建造工艺，先截断河道，筑坝排水、河道清淤；然后固化软弱地基，深层搅拌桩施工，接着在上方依次铺设双向土工格栅、下层土工布、滤水管、碎石层、中层土工布、HDPE防渗膜、上层土工布、垫层；浇筑时将应急事故池体分成若干个标段（小池子），分板块施工，在垫层上方完成各板块混凝土浇筑，养护，最终形成一个倒梯形的应急事故池体；最终在混凝土表面涂刷水泥基渗透结晶防水涂料，本发明施工方法科学，在施工效率上、材料利用方面取得了显著效果，同时依托河床选择“最大事故法”事故池建设模式在土地资源紧张、化工行业集群化的当下具有广泛的应用前景和推广价值。
