Abstract
The utility model discloses a kind of canal bottom sand setting filtering captation, in canal two bottom sides, one sediment deposition groove is respectively set, row's ripple filter pipe is laid between the groove of canal bottom two, screen pipe caliber is more than avris in the middle part of canal bottom, lay stainless steel filtering net in screen pipe top, it is in triangular form to make screen pack, is easy to silt to collect in stillpot.Thus, using canal bottom Water-collecting filtering mode, a set of buried surface irrigation water filtering system is formed, the irrigation water after being filtered in channel is flowed into buried cistern by filter pipe, and the water that filtering is not carried out flows into downstream by channel.The dirts such as powder, sand and incrustation scale that the utility model is easy in irrigation water collect, beneficial to cleaning.
Description
Technical field
The utility model belongs to small on-farm irrigation structures field, is a kind of canal bottom sand setting filtering captation, utilizes canal
Road underdrain, the dirts such as earth's surface irrigation water medium silt, sand and incrustation scale are implemented to filter.
Background technology
China river course belongs to fully-loaded stream more, is characterized in, sediment charge is big, and sediment grain size is small, not disposable.For
Fully-loaded stream, how to quote surface water to implement the water-saving irrigation techniques such as sprinkling irrigation, drip irrigation is current irrigation problem.Therefore, this hair
It is bright to use canal bottom Water-collecting filtering mode, irrigation water sand grain content in channel is reduced, makes surface-water irrigation water quality sand grain
Content reaches《Slight irrigation engineering design code》(GB/T50485-2009) requirement.
Utility model content
In view of the above-mentioned problems, the utility model proposes a kind of canal bottom sand setting to filter captation, pass through canal bottom stainless steel mistake
Filter screen and ripple filter pipe, implement the filtering of canal bottom to high concentration of sediment channel water, reach surface irrigation particle water thing content in its channel
The standard needed to all kinds of small-sized slight irrigation facilities.
The utility model canal bottom sand setting filtering captation, sediment deposition is designed with along channel bottom surface both sides along water (flow) direction
Groove；Channel bottom surface is also laid side by side filter pipe along water (flow) direction, and filter pipe is located between the side shield of channel bottom surface two, filter pipe outlet
End connects with cistern.
In the above-mentioned filter pipe being arranged side by side, the filter pipe of both sides is more than positioned at middle part filter pipe caliber；And it is arranged side by side
Filter pipe upper surface connect respectively with sediment deposition groove covered with filter screen, filter screen both sides.Thus after filtering in filter pipe
After surface water is further filtered by filter pipe, by flowing in cistern certainly, implement to irrigate by various irrigation systems；Without
The irrigation water of filter, still along channel flow downstream.
The utility model has the advantage of：
1st, the utility model canal bottom sand setting filtering captation, positioned at channel bottom, category is independent, concealment system, does not influence
The arrangement of channel and its operation, it is easy to transform existing channel；
2nd, in the utility model canal bottom sand setting filtering captation, design sediment deposition groove be easy to powder in irrigation water,
The dirts such as husky and incrustation scale collect, beneficial to cleaning；
3rd, in the utility model canal bottom sand setting filtering captation, screen pack and screen pipe belong to free-standing, are easy to tear open
Remove, clean.
Brief description of the drawings
Fig. 1 is that canal bottom of the present invention sand setting filters captation sectional side view；
Fig. 2 is that canal bottom of the present invention sand setting filters captation cross-sectional view.
In figure：

Embodiment
The utility model canal bottom sand setting filtering captation, including channel 1, filter screen 2, filter pipe 3 and cistern 4, such as Fig. 1
It is shown.
As shown in Fig. 2 channel 1 is designed as trapezoidal cross-section concrete lining structure, slope coefficient is between 1.5~3.0, canal
A width of 2.0~5.0 meters of the bottom of road 1；And the two bottom sides of channel 1 are designed with the baffle plate 5 along the water (flow) direction of channel 1 so that baffle plate 5 with
The sediment deposition groove 6 along the water (flow) direction of channel 1, about 0.2~0.3 meter of groove width are formed between channel two side.The filter pipe 3 uses
Ripple filter pipe, it is arranged side by side along the water (flow) direction of channel 1, between the two bottom sides baffle plate of channel 1, is layed in the bottom of channel 1,
Dismantled and assembled mounting means is used between the bottom of channel 1.Wherein, the caliber of filter pipe 3 positioned at middle part is managed more than both sides filter pipe 3
Footpath, make filter pipe 3 that rear upper surface be arranged side by side and form the low gradient in middle high both sides.The above-mentioned upper table of filter pipe 3 being arranged side by side
The dirts such as the powder in surface water, sand and incrustation scale are filtered by filter screen 2, covered with stainless steel filtering net 2 in order to prevent canal in face
The bottom filtering material of road 1 is washed away, and the thickness of filter screen 2 is no less than 3mm, and to ensure filter effect, the mesh number of filter screen 2 is not preferably less than
200 mesh, according to slight irrigation facility needs, the mesh number of design filter pipe 3 is more than or equal to the mesh number of filter screen 2.2 liang of sides of filter screen and channel
The baffle plate 5 of 1 both sides connects, between the two using removable connected mode.And because the caliber of middle part filter pipe 3 is more than other drainages
The caliber of pipe 3, and then filter screen 2 is formed the low gradient in the high both sides in middle part；Thus after the filtering of filter screen 2, remain on filter screen 2
The dirts such as powder, sand and incrustation scale can tumble along filter screen 2, be collected in the sediment deposition groove 6 of the two bottom sides of channel 1.
Cistern 4 is buried, the end of channel 1 is placed in, positioned at the bottom of channel 1 or the both sides of channel 1.The outlet of filter pipe 3
End connects with cistern 4, after the surface water in filter pipe 3 is by filter pipe 3 further filtering after filtering, by flowing to water storage certainly
In pond 4, implement to irrigate by various irrigation systems；Filtered irrigation water, still flow to downstream along channel 1.
The designed outlet water Q=bLV of above-mentioned irrigation systemg, captation can be filtered according to the utility model canal bottom sand setting
It is determined that；Wherein in formula：Q be irrigation system designed outlet water, unit m3/d.B is filtering layer section width suitable for reading, i.e., along channel
The baffle plate spacing of water (flow) direction, unit m.L filters the length of captation, unit m for sand setting.Vg is by filter screen and mistake
Water volume flow rate after chimney filter, unit m/d.
