Water intake pipeline structure passing through soft foundation dike below flood level and construction method
The invention discloses a water intake pipeline structure penetrating through a soft foundation dike below the flood level and a construction method. The water intake pipeline structure comprises a pipeline, a gate valve well, a concrete pipe bed, a high-pressure jet grouting pile continuous wall, cement soil mixing piles, a geogrid, backfill clay, a mud stone pavement and a concrete key wall. After the dike is broken and excavated to the pipeline dike-penetrating design elevation, the cement soil mixing piles are fully arranged, and the high-pressure jet grouting pile continuous wall is arranged below the gate valve well; a plain concrete cushion layer, the gate valve well, the concrete key wall and the concrete pipe bed are poured, the water intake pipeline is arranged, and the pipelinebehind the gate valve well is wrapped with concrete; the geogrid is placed during clay backfilling, and layered soil filling is carried out; the dike top is restored by using the mud stone pavement; and the gate valve well is provided with a gate valve, and the gate valve is connected with an operation rod. The invention further discloses the construction method of the structure for the water intake pipeline to penetrate through the soft foundation dike below the designed flood level. The water intake pipeline structure penetrating through the soft foundation dike below the flood level and theconstruction method can eliminate differential settlement of the dike-penetrating section, cuts off a seepage channel at the contact position of the pipeline and a dike body, improves the anti-skid stability of a dike slope, and is novel in structure and convenient to implement.
本发明公开了一种洪水位以下穿越软基堤防的取水管道结构及施工方法，包括：管道、闸阀井、混凝土管床、高压旋喷桩连续墙、水泥土搅拌桩、土工格栅、回填粘土、泥结石路面、混凝土刺墙。破堤开挖到管道穿堤设计高程后，满堂红布置水泥土搅拌桩，在闸阀井下方布置高压旋喷桩连续墙。浇筑素混凝土垫层、闸阀井、混凝土刺墙、混凝土管床，安装取水管道，闸阀井后方的管道用混凝土包裹。回填粘土时放置土工格栅，并分层填土。用泥结石路面恢复堤顶。闸阀井设闸阀，上接操作杆。还公布了取水管道设计洪水位以下穿越软基堤防的结构的施工方法。本发明可消除穿堤段不均匀沉降，截断管道与堤身接触处渗流通道，提高堤坡抗滑稳定性，结构新颖，实施方便。
