Description
Technical field
The utility model relates to a kind of lock control of water conservancy irrigation and drainage system technical field more particularly to ecological efficient modelings
Expect the irrigation and drainage channel of component and its composition.
Background technique
Water conservancy is the lifeblood of agricultural, and irrigation is to improve the basic assurance of the comprehensive grain production ability.China's agricultural is used at present
Water accounts for 60% or more total water, and water efficiency of irrigation is low, the serious development for restricting the secondary industry and the tertiary industry." 12th Five-Year Plan " end farmland
Water efficiency of irrigation only 0.53, and " 13 " planning requirement, to the year two thousand twenty, water efficiency of irrigation is increased to 0.55 or more.It arrives
The year two thousand thirty, water efficiency of irrigation was increased to 0.6 or more.
Irrigation canal antiseepage is to improve the directly most effective measure of water efficiency of irrigation.Concrete impervious canal is answered at present
With very extensive.But the construction of cast-in-situ concrete permeability-reducing channel road is complicated, and very climate condition limits, cost is big and construction speed without
Method is controlled.Forecasting concrete anti-leaking channel prefabricated section is generally smaller simultaneously, and seam is more, and construction quality is difficult to ensure, channel is whole
Property is poor.Discharge conduit mostly uses soil property channel at present simultaneously, easily silts up, influences draining and water drainage.
Such as " channel of a kind of U-shaped anti-rot plastic channel component and its composition " (patent No. 201520068195.3) described work
Make process: U-shaped anti-rot plastic channel component is connected in sequence, wherein two adjacent components are connected by connector 6, even
Connector 6 and canal wall 1 are tightened with screw after coating marine glue on the inner sidewall of fitting 6 and on the lateral wall of canal wall 1, successively connected
Composition channel is connect, channel insertion agricultural land soil can be used to field irrigation or draining.But 1~2m of single component length, needs
After component is first in turn connected into channel, then by above-mentioned channel insertion farmland, this will make above-mentioned component channel too long, and construction is not
Just and cause canal wall and farmland ditch soil compatible degree poor, there are still larger defects in the application.It is provided by the utility model
The agricultural irrigation channel course of work of plastic member and its composition: adjacent by the smooth good farmland ditch of first Component Embedding
Head end link slot, the convex wing edge of another component be overlapped in the end link slot of first component, recessed edge of a wing blending bolt for two structures
Part is tightened, and makes construction flexibly and fast, strong operability, and cover board and earthing plantation are installed on component.
It is entitled " channel of a kind of light-duty plastics channel component and its composition " such as patent No. 201520068717.X,
Its catenation principle is: being aligned placement with groove 8 by voussoir 7, crosses between voussoir 7 and groove 8 plus the barrier sheet for being coated with marine glue
10 and it is tightened with voussoir 7 and groove 8 with plastics screw, barrier sheet 10 effectively prevents element joints and leak occurs
Situation is connect with groove 8 using voussoir 7, facilitates the installation and removal of component, and barrier sheet 10 is approximately equal to component section.Such as
The patent No. 201520068741.3, it is entitled " channel of a kind of light-duty anti-corrosion final stage plastics channel component and its composition ", connect
Connecing principle is: wherein two adjacent components are aligned placement with groove by link block, are coated on the outside of junction with barrier sheet anti-
It is tightened with link block and groove with plastics screw after glue, by link block, groove is Chong Die with barrier sheet links together simultaneously
Marine glue is coated on barrier sheet, the connection type of above-mentioned 2 patents all employs connector, barrier sheet or barrier sheet, increases
The trouble of assembling is added, the utility model can reach simultaneously not to be increased above-mentioned components and reach identical technical effect.And
Above three patent is not provided with a reduction moisture evaporation, further increases water efficiency of irrigation, and earthing plantation meets life
State theory and requirement, the device suitable for ecological agriculture engineering irrigation.
