Pipeline foundation trench shallow dewatering structure and construction method
The invention relates to a pipeline foundation trench shallow dewatering structure and a construction method, and relates to the technical field of dewatering structures. The structure comprises a foundation trench; a plurality of mounting holes are formed in the bottom of the foundation trench; filter pipes are inserted into the mounting holes; a vacuum air suction film is laid on the tops of the filter pipes; a water pumping pipe is arranged on the side, opposite to the filter pipes, of the vacuum air suction film; the water pumping pipe is communicated with the filter pipes; and a vacuum pump is arranged at the end, away from the filter pipes, of the water pumping pipe in a communicated mode. Opening the vacuum pump to pump air, and pumping accumulated water at the bottoms of the filter pipes can realize dewatering. In the process, silt can be filtered under the action of the vacuum air suction film, so that the silt content of accumulated water discharged finally is small, silt loss can be effectively reduced, the structural stability of soil around the foundation trench is effectively guaranteed, and the soil around the foundation trench is not prone to loosening and sinking.
本申请涉及一种管道基槽浅层降水结构及施工方法，涉及降水结构技术领域。其包括基槽，所述基槽底部开设有若干安装孔，所述安装孔内插设有滤管，所述滤管顶部铺设有真空吸气膜，所述真空吸气膜背向滤管的一侧设置有抽水管，所述抽水管与滤管相连通，所述抽水管远离滤管的一端连通设置有真空泵。打开真空泵抽气，将滤管底部的积水抽出，以实现降水。此过程中，泥沙可在真空吸气膜的作用下进行过滤，从而可使得最终排出的积水含泥量较少，可有效减少泥沙流失，有效保障基槽周边土质的结构稳固性,使得周边土质不易松动下沉。
