Abstract

The invention discloses a hollow drainage ridge for a flat dam strip-field. The hollow drainage ridge is a ridge which is built by casting a building material and of which the inner cavity is provided with a drainage sewer; a river of which the total capacity height is lower than a bottom line of a plough layer of a field along a line and the water at the tail is drained into a drop section through the underside of a transverse ridge is designed; drain holes of fields along the line are formed on two side walls of the ridge near a crossed field corner above the total capacity height; and the ridge crossed position with the drain hole is provided with a pit and cover plate, which exceeds a vicinity range of the tail drain hole of the ridge crossed position. The invention has the advantage that: the hollow drainage ridge has enough drop, quickly drains irrigation water and rainwater timely, reduces the flood discharge pressure of irrigation ditches to prevent rainstorm from flooding the field to avoid flooding crops, can reduce the loss of soil nutrients, effectively solves a problem of wet damage in the field timely to facilitate soil permeability, creates high yield conditions for the crops, does not influence irrigation from one field to another, can avoid a dispute of field flooding due to drainage, prevents drained water from being blocked by irrigation channel water or irrigating the field by mistake, has two purposes of the drainage sewer and an aisle ridge, drains water in a labor-saving and time-saving mode, and avoids the scouring of rainstorm and weed coverage of the field.

Description

Hollow drainage ridge for flat dam strip-field

Technical field

The present invention is the ridge that a kind of inner chamber has the cloudy canal of draining.

Background technology

There is abundant water condition in Pingba irrigated area, is beneficial to a large amount of development winter and spring vegetables economical production.But Pingba physical features is smooth, most fields towards the draining drop in feed ditch or adjacent field higher than field arable layer bottom flat line, part field does not even have draining drop, it does not possess irrigation and drainage good farmland factor easily, it has drainage speed to cause soil nutrient loss amount large slowly, feed ditch water blockage outfall is filled with field even by mistake, soil suffers wet injury invasion and attack to hinder air to enter, hinder crop root to stretch and beneficial microbe activity, feed ditch flood carrying capacity causes the above-mentioned multiple negative factor that is unfavorable for crop normal growth that heavy rain floods large stretch of field along the line to resist plant growth not, draining affects the deficiency that adjacent Tagayasu Den easily causes soaking field dispute ...

Summary of the invention

The present invention is directed to all deficiencies of above present situation, provide a kind of and can solve above all problems, excavate the hollow drainage ridge for flat dam strip-field of agricultural produce potentiality.Present design is as follows: hollow drainage ridge for flat dam strip-field, comprises Huo Feitiao field, bar field ridge; The inner chamber that it waters block for building materials has the ridge of the cloudy canal of draining, between each two feed ditch field along the line, to be the replacement ridge of entity ridge between the longitudinal field of two rows, the total appearance stream of its design height is lower than field arable layer bottom flat line along the line, and rear enters the river of drop place section below horizontal ridge; Each field outfall along the line, is located at respectively on this ridge two side on the side, angle, intersection field on its total appearance stream height; This ridge infall that has outfall, has heavy hole and cover plate over annex scope outside this place's tail end outfall.

From above-mentioned design, the inner chamber that building materials water block has the hollow drainage ridge of the cloudy canal of draining, replace between each two feed ditch field along the line the entity ridge of (being between the longitudinal field of each two row of current direction), rise as draining drop is higher than arable layer bottom flat line with do not have the flat dam strip-field of draining drop or non-field to provide unimpeded, the drainage system that has enough draining drops, reach and avoid feed ditch water logging evil good farmland along the line, discharge in time irrigation water, rainwater and feed ditch soak water in field at ordinary times, both can avoid feed ditch water blockage outfall or fill with field by mistake from this System drainage, avoiding shutoff to irrigate mouth will wait for that water in field drains and just can carry out and waste a large amount of stand-by period, can need in feed ditch string filling situation, allow feed ditch accept field draining again, drainage ridge and feed ditch successively interval are controlled, make smooth and easy other feed ditch of downstream, covalency of returning of draining, reverse low yield immersion He Xiashi field, field present situation, promote plant growth, the cloudy canal of the draining passageway ridge double-purpose functional of holding concurrently, avoid mistaking and close water or draining and soak the adjacent field of evil and affect farming and cause soaking field dispute, reverse earth ridge and often suffer frost invasion and attack, heavy rain washes away, arid breach destroys and causes long-term work consuming to repair the backwardness of ill ridge, avoid the effect of long-term labor intensive cleaning limit, field weeds, the total cavity holding on stream height of its design, plays the violent water of excretion heavy rain, alleviates feed ditch flood discharge pressure, avoids heavy rain to flood large stretch of field along the line and drowned crop causes this season to be lost, ridge sluice gate along the line is located at respectively and intersects on other this ridge two side, angle, field, play a part a plurality of sluice gates utilize a heavy hole and a set of cover plate and reduce this ridge operating expenses, saving ridge body is built material, this ridge infall that has sluice gate, there are the heavy hole and the cover plate that surpass annex scope outside this place's tail end outfall, it is heavy cheat deposition fall by mistake foreign material in canal, do not allow channel, (silt can not wash away and can deposit with water under hydraulic condition), the guarantee unimpeded effect in Geng Neiqu road of entering, its cover plate is regular outlet of drawing clearly hypostasis.

With to feed ditch or to the condition ratio of the adjacent field draining without draining drop, it has enough draining drops to get rid of rapidly at any time the violent water of irrigation water and heavy rain, alleviating feed ditch flood discharge pressure avoids heavy rain to flood large stretch of field along the line and drowned crop, can reduce soil nutrient loss amount, effectively solving at any time in field wet injury, to be beneficial to soil ventilative, for crop is created high yield condition, avoid drawing clearly channel and field internal drainage ditch, neither affect field string and fill with operation, can avoid again mistaking and close water or draining and affect adjacent Tagayasu Den and do to cause soaking field dispute, avoid draining to suffer feed ditch water blockage or fill with field by mistake, there is the cloudy canal of the draining passageway ridge double-purpose functional of holding concurrently, draining saving of work and time is laborsaving, avoid heavy rain to wash away the advantage with the climing field of weeds.
