Dewatering and drainage recycle treatment device for deep foundation pit

Abstract

The invention discloses a dewatering and drainage recycle treatment device for a deep foundation pit and relates to a water treatment device. The dewatering and drainage recycle treatment device comprises silt filter tanks, oil spot filter tanks, silt filter screens, water inlet pipes, water outlet pipes, silt leak-off pipes, oil spot leak-off pipes and an automatic electrical control system; water inlets of the silt filter tanks are connected with water outlets of the water inlet pipes, and water inlets of the water inlet pipes are externally connected with water pumps; the silt filter screens are arranged between the oil spot filter tanks and the silt filter tanks; outlets of the water outlet pipes of the oil spot filter tanks are externally connected with site water storage tanks; the silt filter tanks are provided with the silt leak-off pipes; the oil spot filter tanks are provided with the oil spot leak-off pipes; outlets of the oil spot leak-off pipes are externally connected with a municipal sewage pipe network; the automatic electrical control system is provided with a floating ball magnetic water level gauge and a water level signal control circuit and is arranged on a water storage tank on a construction site; the output end of the floating ball magnetic water level gauge is connected with the water level signal control circuit; and the output end of the water level signal control circuit is externally connected with the water pumps at the water inlet ends of the water inlet pipes.

Description

technical field [0001] The invention relates to a water treatment device, in particular to a deep foundation pit drainage reuse treatment device suitable for construction sites. Background technique [0002] At present, the dewatering and drainage of deep foundation pit projects generally adopts the temporary construction of three-stage sedimentation tanks, which are discharged into the municipal sewage pipe network after sedimentation. This traditional method, on the one hand, does not make reasonable use of it, resulting in the waste of groundwater resources in deep foundation pits, which deviates from the national water-saving call for green construction; The material-saving call for green construction is violated; moreover, due to the continuous reduction and discharge of groundwater, if no replenishment measures are taken, the balance of groundwater around the foundation pit will inevitably be destroyed, thereby causing serious damage to the safety of surrounding buildi...
