Abstract
The utility model discloses a hollow drainage and irrigation pipe, which comprises an outer pipe and a plurality of drainage and irrigation holes arranged on the outer pipe. The utility model is characterized in that the outer pipe is also provided with a main water pipe inside the pipe, and a plurality of inner-wall drainage and irrigation holes are arranged on the wall of the main water pipe where is higher than the position of the outer-pipe drainage and irrigation holes. Compared to the prior art, the utility model is not easy to be blocked.
Description
Technical field
The utility model relates to a kind of irrigation and drainage pipes, relates in particular to a kind of hollow irrigation and drainage pipes.
Background technology
No matter existing irrigation and drainage pipes is draining or pours water, all be to allow water by being distributed in the irrigation and drainage hole of tube wall, when moisture content passes the irrigation and drainage hole, can drive mostly and with sand mud composition, accumulate over a long period down, just can not produce drainage again with passing the irrigation and drainage hole plug of tube wall, but as enlarging at the irrigation and drainage bore dia of tube wall, the body compression strength that will cause outlet pipe reduces, cause body to break, and as the long-pending sand mud of big plastochondria, via the irrigation and drainage hole after enlarging, when entering in the pipeline, just can gather in the bottom of pipeline, reduce the drainage area of pipeline, cause blocking pipe even.And when this irrigation and drainage pipes was used in the slope, the water outlet position of existing irrigation and drainage pipeline had plant to take root, and after plant grows up, just can stop up the delivery port of irrigation and drainage pipelines.This kind takes root because of plant, cause the generation of clogging, main also is because of the water outlet position at drain water piping, a large amount of sand mud are arranged, tied the bottom of gathering in the pipeline by water alluviation, if alluviation to the water outlet position near pipeline, just can become the hotbed of plant germination growth, when plant branch is leafiness grow up after, delivery port that just can blocking pipe.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology and provides a kind of can not causing allow the hollow irrigation and drainage pipes of silt blocking pipe delivery port.
For achieving the above object, the utility model has adopted following technical proposals:
This hollow irrigation and drainage pipes comprises outer tube and is opened in outer tube irrigation and drainage hole on the outer tube that also be provided with a main channel outside in the pipeline, the position that is higher than outer tube irrigation and drainage hole on the wall of main channel is provided with some inwall irrigation and drainage hole; Described main channel is a pipe in, and this inwall irrigation and drainage hole is arranged on the inwall of inner tubal wall both sides.
Described inwall irrigation and drainage hole is arranged at and manages highly place in the inner tube wall 1/2; Described tube-surface is concavo-convex alternate interior tube-surface and outer tube-surface.
Described outer tube comprises discontinuous plurality of sections, and every section diminishes at two ends places and to be connected with interior pipe.
Beneficial effect
By technique scheme, thereby this utility model has following beneficial effect:
1. because the gateway, external irrigation and drainage hole of irrigation and drainage pipeline, be design near in the bottom, after the earth that surrounds pipeline is full of moisture content, just can find that outside the pipeline horizontal level of moisture content is higher than in pipeline interior in the irrigation and drainage hole near the central horizontal position, therefore just produce head pressure by two uneven positions of difference, and this head pressure, just can be the outer moisture content of pipeline, be advanced in the external irrigation and drainage hole of duct bottom by head pressure and penetration, irrigation and drainage hole through inherent is pushed in the main channel, more again via main channel, and current drainage goes out outside the pipeline, thus the existing picture that the utmost point is not easy to stop up.
2. because in drainage procedure, just utilize the self-filtration of sand mud, head pressure and penetration infilter moisture content in the irrigation and drainage hole of duct bottom, so during the draining running, also do not have the generation of bath pressure.Therefore can not drive a large amount of sand mud particles naturally, enter in the pipe of irrigation and drainage duct, cause and stop up situation.

Embodiment
Below in conjunction with accompanying drawing the utility model is made further instruction.
As Fig. 1, Fig. 2, hollow irrigation and drainage pipes shown in Figure 3, comprise outer tube 1 and be opened in outer tube irrigation and drainage hole 2 on the outer tube that also be provided with a main channel outside in the pipeline, the position that is higher than outer tube irrigation and drainage hole on the wall of main channel is provided with some inwall irrigation and drainage hole 3.Described main channel is a pipe 4 in, and this inwall irrigation and drainage hole is arranged on the inwall of inner tubal wall both sides.Described inwall irrigation and drainage hole is arranged at and manages highly place in the inner tube wall 1/2; Described tube-surface is concavo-convex alternate interior tube-surface and outer tube-surface.
Because the gateway, external irrigation and drainage hole of irrigation and drainage pipeline, be design near in the bottom, after the earth that surrounds pipeline is full of moisture content, just can find that outside the pipeline horizontal level of moisture content is higher than in pipeline interior in the irrigation and drainage hole near the central horizontal position, therefore just produce head pressure by two uneven positions of difference, and this head pressure, just can be the outer moisture content of pipeline, be advanced in the external irrigation and drainage hole of duct bottom by head pressure and penetration, irrigation and drainage hole through inherent is pushed in the main channel, more again via main channel, and current drainage goes out outside the pipeline, thus the existing picture that the utmost point is not easy to stop up.Because in drainage procedure, just utilize the self-filtration of sand mud simultaneously, head pressure and penetration infilter moisture content in the irrigation and drainage hole of duct bottom, so during the draining running, also do not have the generation of bath pressure.Therefore can not drive a large amount of sand mud particles naturally, enter in the pipe of irrigation and drainage duct, cause and stop up situation.
Fig. 4, Fig. 5, Fig. 6 are second kind of embodiment of the utility model, and it is implemented different places and be that described outer tube 1 ' comprises discontinuous plurality of sections with first kind, and every section diminishes at the place, two ends and to be connected with interior pipe 4 '.
