Abstract
The utility model provides a farmland drainage concealed pipe with coatings of composite out-packing filter materials, comprising a suction pipe, a straw rope is tightly winded at the outer wall of the suction pipe to form a wrapped layer, a piece of earthwork cloth wraps the straw rope to form a filter layer, a nylon rope is winded at the external layer of the earthwork cloth. the diameter of the straw rope is 2 - 3 cm, the coating earthwork cloth is formed by cloth strips with a width of 20 cm and a thickness of 1 mm. The farmland drainage concealed pipe in the utility model uses the principle of reverse filtering to design the structure of out-packing filter materials, can effectively prevent soil particles from entering into the concealed pipe, prevent the blocking of the concealed pipe, stabilize the surrounding soil, improve the water seepage capability of the pipe channel, and improve the drainage effect of the concealed pipe.
Description
One, technical field
The utility model belongs to the Agricultural Water-Soil Engineering technical field, is specifically related to a kind of agricultural drain hidden pipe that coats compound outsourcing filtrate.
Two, background technology
The outsourcing filtrate of hidden pipe is an infiltration ability of improving the hidden pipe passage, improves the important step of closed drainage ability, so its structure design is the importance of farmland plastic hidden pipe drainage works design.Traditional farmland hidden tube drainage engineering because building size is little, pipe canal digging, filtrate fill, hidden pipe is laid and backfilling of earthwork all by manually finishing.Along with the building size of farmland plastic hidden pipe drainage works constantly enlarges, mechanized construction is universal day by day, and operation is often disposable finishes for trench digging, pipe laying, backfill etc.Therefore exploitation cheap, efficiently the outsourcing filtrate and and the suction water pipe colligation be integral, the composite pipe of mechanized construction is convenient in formation, for improving hidden pipe engineering construction efficient, improving closed drainage effect and application life, have important applied value and broad prospect for its application.
Three, utility model content
Goal of the invention: the utility model provides a kind of agricultural drain hidden pipe that coats compound outsourcing filtrate, can improve farmland plastic hidden pipe draining infiltration ability and prevent that suction water pipe silts up.
Technical scheme: a kind of agricultural drain hidden pipe that coats compound outsourcing filtrate, comprise suction water pipe, described suction water pipe outer wall closely twines straw rope formation wraps up in layer, and straw rope is coated with geotextiles and forms filtering layer, the outer nylon rope that twines of geotextiles.The diameter of described straw rope is 2-3cm.The geotextiles of described coating is made up of the cloth of wide 20cm, thick 1mm.
Beneficial effect:
1, the structure of the anti-principle design outsourcing filtrate of filtering of the utility model utilization can stop soil particle to enter hidden pipe effectively, avoids hidden pipe to block, and can cross stable soil on every side simultaneously, improves the infiltration ability of hidden pipe passage, improves the closed drainage effect.
2, the utility model can be gathered materials on the spot, cost is low, and filtrate and tubing are integrated, help mechanization and bury underground.
3, draw materials easily approach, reasonable structural design, easy canoe of the utility model administered the area in stain evil field, salt-soda soil and had promotion and application widely and be worth implementing closed drainage.
Four, description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional view of the utility model closed drain;
Fig. 3 is a composite filtering material construction process schematic diagram;
Among the figure, 1-suction water pipe, 2-straw rope, 3-geotechnique cloth, 4-nylon yarn, 5-conveying device.
Five, the specific embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the utility model:
As shown in Figure 1, 2, comprise suction water pipe 1 in this utility model structure, straw rope 2, geotechnological cloth 3, nylon yarn 4, conveying device 5 combines.
As shown in Figure 3, with 1 of suction water pipe on a conveying device 5, straw rope 2 (centre does not interspace) at gutter outside coiling diameter 2-3cm, wrap up in the geotechnological cloth 3 (not revealing straw rope) of 1 layer of wide 20cm, thick 1mm again, twine nylon yarn 4 at last one, straw rope 2, geotechnological cloth 3 are become one with suction water pipe 1.
A kind of agricultural drain hidden pipe that coats compound outsourcing filtrate comprises suction water pipe 1, and described suction water pipe outer wall closely twines straw rope 2 and forms integument, and straw rope outsourcing geotechnique cloth 3 forms filtering layer, the outer nylon yarn 4 that twines of geotextiles.The straw rope diameter that described suction water pipe outer wall closely twines is 2-3cm, forms to wrap up in layer.The outer geotextiles that coats of described integument is the cloth of wide 20cm, thick 1mm, forms filtering layer.
Claims (3)
1. agricultural drain hidden pipe that coats compound outsourcing filtrate, it is characterized in that comprising suction water pipe (1), described suction water pipe outer wall closely twines straw rope (2) and forms integument, and straw rope outsourcing geotechnique's cloth (3) forms filtering layer, the outer nylon yarn (4) that twines of geotextiles.
2. the agricultural drain hidden pipe of the compound outsourcing filtrate of coating according to claim 1 is characterized in that the straw rope diameter that described suction water pipe outer wall closely twines is 2-3cm, forms and wraps up in layer.
3. the agricultural drain hidden pipe of the compound outsourcing filtrate of coating according to claim 1 is characterized in that the outer geotextiles that coats of described integument is the cloth of wide 20cm, thick 1mm, forms filtering layer.
