Embodiment Construction

[0022] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] A water and soil separation device in the upper reaches of a small and medium-sized river course according to the present invention, a plurality of separation devices are sequentially arranged along the upstream river course, the river course between two consecutive separation devices is a intercepting and filtering area, and at least one intercepting and filtering area includes one serious soil loss reach.

[0024] Such as figure 1 As shown, the structure of the present invention includes a river intercepting bin 1 arranged in the river channel, and the river intercepting bin 1 can be arranged at a position where the soil quality on both sides of the river channel is sparse, and the separated silt and silt can directly cover the nearby land to improve the soil quality of the river bank in the area. Reduce transportation c...

Abstract

The invention discloses a small and medium-sized riverway upstream water-soil separation device comprising a river interception bin; a sludge discharge bin and a filtered water discharge bin are fixedly arranged in a river interception plate, a piston pipeline is arranged on the upper portion of the filtered water discharge bin, and a negative pressure pipeline is arranged on the lower portion ofthe filtered water discharge bin; a spiral blade is arranged in the sludge discharging bin, a water inlet is formed in the bottom of the sludge discharging bin, a filtering opening is formed between the sludge discharging bin and the negative pressure pipeline, and the filtering opening is covered with a sludge filtering layer; a piston is arranged in a piston pipeline of the filtered water discharge bin, a lifting rod is arranged on the upper portion of the piston, a rack is arranged on the lifting rod in the length direction of the lifting rod, an incomplete gear meshed with the rack is arranged above the filtered water discharge bin, a plurality of through holes are formed in the piston, and turnover covers are hinged to the through holes. Sand and sludge in a riverway can be continuously filtered, and water and soil loss and downstream riverbed lifting are avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a water-soil separation device in the upper reaches of a medium-sized river course. Background technique [0002] Due to excessive land development, the vegetation in the middle and upper reaches of the river is destroyed, and the water and soil loss is serious. Especially after the heavy rain, the surface sediment is rolled up and flows downstream along the river, blocking the river along the way, and the downstream river bed is raised, which is likely to cause floods in the downstream area. It causes serious damage to human property and destroys the ecological environment. [0003] The treatment of river water containing a large amount of sediment is a difficult water conservancy problem in the world. Even if the river water containing a large amount of sediment is stored in the reservoir to naturally settle the sediment after the dam is built, it will cause ex...
