Problems solved by technology

[0007] In order to solve the problem that existing conventional technologies are suitable for water intake in water bodies with wider river channels or deeper water depths, and there are no technical problems of water intake structures and water intake processes for seasonal rivers, one of the purposes of the present invention is to solve the problem of small river runoff and Seasonal influence is greater, and the river bed has been dry for a long time, resulting in a large floodplain area and difficult technical problems in water intake
[0008] The second object of the present invention is to solve the technical problem that the surface water intake structure has no construction site
[0009] The third purpose of the present invention is to solve the technical problem of secondary sand settling caused by the high sediment content of the river water when taking water from the current seasonal shoal rivers, and to provide a water intake process suitable for seasonal shoal rivers

Embodiment 1

[0036] In northern Shaanxi, river runoff is small and is greatly affected by seasons; the river bed has been dry for a long time, resulting in a large area of ​​floodplain; water intake is difficult and there are often no suitable construction sites for structures. In order to solve this problem, this embodiment provides a seasonal shoal river floodplain type water intake structure, the body is located below the surface of the river channel 1 and the floodplain 8, the body includes the seepage channel 2 and the collection channel connected with the seepage channel 2 A water pipe 4, a seepage canal inlet pipe 11 is embedded in the middle of the seepage canal 2, and a water inlet hole 12 is provided on the seepage canal water inlet pipe 11; And the grit chamber 5 and the water absorption well 6 successively communicated with the water collection well 3 , the bottom of the water absorption well 6 is provided with a submersible sewage pump 7 .

[0037] Its structural diagram is as...

Embodiment 2

[0040] In this embodiment, on the basis of Embodiment 1, the slotting direction of the seepage ditch 2 is parallel to or forms a certain angle with the water flow direction, and the angle is greater than 120°. The setting method of the seepage canal 2 should intercept the whole river course to obtain a larger runoff.

[0041] In this embodiment, the upper part of the water inlet pipe 11 of the seepage ditch is filled with a filter layer. The filter layer is provided with 3-4 layers, each layer is 200-300m thick, the upper surface of the uppermost filter layer is flush with the river bed, and the thickness of each filter layer decreases sequentially from top to bottom, that is, the top is thick and the bottom is thin. The particle size of the material is fine at the top and coarse at the bottom.

[0042] In the present embodiment, the width of the water inlet hole 12 of the water inlet pipe 11 of the seepage ditch is 20mm, such as figure 2 As shown, the length is 3~5 times o...

Embodiment 3

[0044]In this embodiment, on the basis of Embodiment 1 and Embodiment 2, an inspection well 9 is also arranged on the seepage trench 2, and a manhole 13 and a manhole 14 are arranged on the upper surface of the manhole. A ladder 15 is provided in the hole 14 . The maintenance personnel can enter from the manhole 13 and the manhole 14, and go down into the seepage trench by the ladder 15 to carry out maintenance on each equipment.

Abstract

The invention relates to the technical field of surface water intake, in particular to a flood land water intake structure and technology for a seasonal shallow river. The water intake structure is arranged beneath the earth surface and comprises seepage channels, a water inlet pipe, a water collecting pipe, a water collecting well, a grit basin, an inspection well, a suction well and a lift pump; normal operation of the seepage channels in the flood season is strictly ensured; when a proper position does not exist, the water intake structure can be arranged on the flood land; the water intake technology comprises the steps of water intake via the seepage channels (includes filtering with a filler), degritting via the grit basin, lifting, swirling degritting, filtering with fiber balls and filtering with sintered tubes; the problem of the flood land water intake technological process for the seasonal shallow river is solved, the water quality is ensured, and the operation is reliable.

Description

technical field [0001] The invention relates to the technical field of surface water intake, in particular to a seasonal shoal river floodplain water intake structure and a water intake process. Background technique [0002] According to the type of water source, water intake structures can be divided into two categories: groundwater intake structures and surface water intake structures, while surface water intake structures can be divided into fixed type (bank type, river bed type, bucket trough type) and movable type according to the structural form of water intake structures. There are two types (floating boat type, cable car type). On mountainous rivers, there are low dam type and low fence type water intake structures. [0003] Whether the location of river water intake structures is properly selected directly affects the water quality and quantity of water intake, the safety and reliability of water intake, investment, construction, operation management, and comprehens...
