Circulating inflatable submersible draining dewatering well structure and dewatering method
The invention relates to a circulating inflatable submersible draining dewatering well structure. The circulating inflatable submersible draining dewatering well structure comprises a well pipe, an inflation pipe, an exhaust pipe and a water outlet pipe, wherein at least one sealing bag is fixed to a water stop sealing section on the upper portion of the well pipe, and a grouting pipe extends intothe sealing bag; a filtering section and a sediment pipe section are sequentially arranged below the sealing bag; the water outlet pipe extends into the well pipe from top to bottom, wherein the lower end of the water outlet pipe is positioned at the filtering section; one end of the inflation pipe extends into the well pipe, and the other end is connected with a pressure air source; and one endof the exhaust pipe extends into the well pipe, and the other end is connected with a negative pressure source. According to the circulating inflatable submersible draining dewatering well structure,water of surrounding soil can be accelerated to escape to the well pipe in a circulating inflation and deflation dewatering mode, and the drainage and dewatering speed is increased; a dewatering wellis economical in manufacturing cost and energy-saving in operation; the well structure is compact in structure, convenient to construct and high in efficiency; the single-well diameter is reduced, thesingle-well cost is reduced, construction adjustability and construction reliability are improved, and the construction procedure is simplified; and the sealing bag is sealed in a grouting mode, so that good sealing effects are achieved.
本发明涉及一种循环充气式潜水疏干降水井结构，包括井管、充气管、抽气管、出水管；井管上部的止水密封段固定至少一密封袋，注浆管伸入所述密封袋内；所述密封袋下方依次为过滤段和沉淀管段；出水管自上而下伸入井管内，其下端位于过滤段；充气管一端伸入井管内，另一端与压力气源连接；抽气管一端伸入井管内，另一端与负压源连接。本发明利用循环充吸气降水的方式能够加速周围土体水分向井管逸出，加快疏干降水速度，降水井造价经济且运营节能；井结构紧凑、施工便捷、效率高；缩减单井直径，降低单井成本，提高施工柔性可调节性，提高施工可靠性，简化施工工序；密封袋注浆密封，密封效果好。
