Abstract

The utility model relates to a drainage ditch, in particular to a novel farmland drainage ditch. The novel farmland drainage ditch comprises a ditch wall and a ditch bottom, the ditch wall is composed of an upper layer and a composite layer located under the upper layer, the upper layer is a common concrete impervious layer, the composite layer is composed of a composite layer I and a composite layer II, the composite layer I and the composite layer II are arranged at intervals in the length direction of the ditch wall, the composite layer I is a non-fine concrete pervious layer, the composite layer II is a common concrete impervious layer, and the ditch bottom is a common concrete impervious layer. The novel farmland drainage ditch can guarantee the flooded farmland drainage and the subsurface water drainage functions of a farmland, and has the effect of back-irrigation of water in the ditch.

Description

A kind of Novel farmland gutter

Technical field

The utility model relates to a kind of gutter, particularly a kind of Novel farmland gutter.

Background technology

At present, in basic farmland is built, the draining while considering heavy rain or flood, easy ponding place, the farmland of being everlasting is provided with the drain ditch in the field of different brackets.

Existing drain ditch in the field, mainly with stone masonry or the design of concrete individual layer homogeneous texture, is laid delivery port in the lower side of field, discharges the unnecessary moisture of field face, or oozes effect draining under vertical by soil.But for the heavier farmland of soil stickiness, under soil is vertical, ooze drain function almost completely lost,, be blocked completely with extraneous soil because ditch body is inner meanwhile.The unnecessary moisture of common gutter Jin Nengjiang field face and topsoil is discharged, and in agricultural land soil, lower floor's moisture cannot discharge, and lost completely the requirement of drainage of farmland subsurface water.

And when dry season, because at the bottom of stone masonry or concrete ditch and furrow bank both sides are closed construction, the moisture storing in ditch body cannot bleed back to field soil again, causes the waste of water resource.

Utility model content

For addressing the above problem, the utility model proposes a kind of Novel farmland gutter, can guarantee water drainage, row's stain function in farmland, there is again the effect that in ditch body, moisture recharges.

Its technical scheme is:

A kind of Novel farmland gutter, comprise furrow bank and bottom of trench, described furrow bank is made up of upper layer and composite bed, described composite bed is arranged on the below of described upper layer, described upper layer is ordinary concrete impervious layer, described composite bed is made up of composite bed I and composite bed II, described composite bed I and composite bed II at furrow bank length direction apart from one another by setting, described composite bed I is non-fine concrete pervious layer, described composite bed II is ordinary concrete impervious layer, and described bottom of trench is ordinary concrete impervious layer.

Further, the slope that described furrow bank is 1:0.3.

The target that the utility model mainly steeps from water drainage, row, to improve the deficiency of existing drain ditch in the field.Compared with prior art, the invention has the beneficial effects as follows:

1. the utility model adopts concrete material, can strengthen ditch body plasticity, effectively controls soil losses, prevents the avalanche of furrow bank inslope.

2. when rainy season, the utility model can pass through the delivery port at two furrow bank tops, discharges field face and the unnecessary moisture of topsoil, meanwhile, can pass through the pervious layer of two furrow bank bottoms, discharges in agricultural land soil, lower floor's moisture, has realized the requirement that farmland water drainage, row steep.

3. when dry season, the utility model can pass through the pervious layer of two furrow bank bottoms, and the Yu Shuike in ditch bleeds back to field soil by furrow bank, improves water resource and recycles.

4. the top of the utility model two furrow banks is impervious layer, prevents the water loss of agricultural land soil upper strata, ensures the required moisture of plant growth.

the specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1 to Figure 3, a kind of Novel farmland gutter, comprises furrow bank 1 and bottom of trench 4, and described furrow bank 1 is made up of upper layer 2 and composite bed 3, and described composite bed 3 is arranged on the below of described upper layer 2.Described upper layer 2 is ordinary concrete impervious layer, and described composite bed 3 is made up of composite bed I 5 and composite bed II 6, described composite bed I 5 with composite bed II 6 at furrow bank 1 length direction apart from one another by setting.Described composite bed I 5 is non-fine concrete pervious layer, and cement consumption is 70～150kg/m ³, aggregate is gravel or rubble, particle diameter is 10～20mm.Described composite bed II 6 is ordinary concrete impervious layer.Described bottom of trench 4 is ordinary concrete impervious layer.The slope that described furrow bank 1 is 1:0.3.

Claims

1. a Novel farmland gutter, comprise furrow bank and bottom of trench, it is characterized in that: described furrow bank is made up of upper layer and composite bed, described composite bed is arranged on the below of described upper layer, described upper layer is ordinary concrete impervious layer, described composite bed is made up of composite bed I and composite bed II, described composite bed I and composite bed II at furrow bank length direction apart from one another by setting, described composite bed I is non-fine concrete pervious layer, described composite bed II is ordinary concrete impervious layer, and described bottom of trench is ordinary concrete impervious layer.

2. a kind of Novel farmland according to claim 1 gutter, is characterized in that: the slope that described furrow bank is 1:0.3.
