Description
Technical field
The utility model is related to a kind of soil improvement structures, more specifically, it relates to a kind of salt-soda soil salt discharge draining knot
Structure.
Background technology
Salt-soda soil is a type of salt aggregation, refer to inside soil contained by salinity influence the normal life of crop
It is long.
Currently, for salt-soda soil improvement often by way of soil removal and replacement, non-saliferous planting soil is laid on salt-soda soil
On, then by planting tree on planting soil, but the salt branch in underground water rises with capillary and is gathered in upper soll layer, makes kind
Planting soil becomes Secondary salinization soil, causes the trees on planting soil to occur dead, reduces the survival rate of trees.
Utility model content
In view of the deficienciess of the prior art, the utility model lies in that providing a kind of salt-soda soil salt discharge discharge structure, have
Improve the effect of trees surviving rate.
To achieve the above object, the utility model provides following technical solution：A kind of salt-soda soil salt discharge discharge structure, packet
Include the salt discharge tap drain being arranged on salt-soda soil and salt discharge time ditch, the salt discharge tap drain include the main line being opened on salt-soda soil,
The first sand gravel layer for being laid in the main line, is laid on the Huang at the yellow sand layer being laid on first sandy gravel stratum
Non-woven fabrics, the salt discharge time are coated on the first planting soil layer on sand bed, first sand gravel layer and the yellow sand layer
The second sand gravel layer that ditch includes the secondary groove being opened on salt-soda soil, is laid in the secondary groove, the secondary groove and institute
Main line connection is stated, non-woven fabrics is coated on second sand gravel layer, second for planting trees is equipped on salt-soda soil
Planting soil layer, the secondary groove are located at the both ends of second planting soil layer, the side of first planting soil layer and described the
Two planting soil layers contradict.
By using above-mentioned technical proposal, rainwater drops onto in the second planting soil layer, under self gravitation effect downward
Infiltration is penetrated into after the second sand gravel layer in time groove, and rainwater is flowed into from secondary groove in main line, through the first yellow sand layer
The bottom of main line is entered after filtering with the first sand gravel layer, and is moved along main line, and salt-soda soil is discharged；When in salt-soda soil
Capillary of the salinity in soil when rising, due to the gap between sand gravel in the second sand gravel layer and the first sand gravel layer
Larger, salinity is difficult to reach the second planting soil layer along the second sand gravel layer and the first sand gravel layer, and the second planting soil layer is made to be difficult to
Salination improves the survival rate of the trees in the second planting soil layer.
The utility model is further arranged to：The main line is in net distribution, and second planting soil layer is located at described
In the region that main line surrounds.
By using above-mentioned technical proposal, so that moisture is arbitrarily flowed in the main line of net distribution, increase moisture
With the contact area in salt-soda soil, salinity more on salt-soda soil can be discharged, reduce the salinity in salt-soda soil, oozed in reduction by moisture
Salinity, reduce the saliferous probability of the second planting soil layer.
The utility model is further arranged to：It is provided with separate layer between first sand gravel layer and the yellow sand layer,
The separate layer includes separation frame between first sand gravel layer and the yellow sand layer, is fixedly connected on the separation
Water accepting layer in frame.
By using above-mentioned technical proposal, when rainwater is from yellow sand laminar flow to the first sand gravel layer, water accepting layer is to moisture
It is absorbed, when being oozed on salinity, water accepting layer also absorbs salinity, makes salinity be not easy to continue to permeate upward, reduces
The saliferous probability of second planting soil layer.
The utility model is further arranged to：It is provided with separation layer between second planting soil layer and salt-soda soil, it is described
Separation layer includes the metalling being laid on salt-soda soil, is laid on the metalling non-woven fabrics is placed on the non-woven fabrics
On supporting rack.
By using above-mentioned technical proposal, the setting of metalling makes the salinity on salt-soda soil be difficult to ooze to the second planting soil
At layer, growth that supporting rack keeps the trees in the second planting soil layer relatively stable；When rainwater will be in the second planting soil layer
When soil washes away, non-woven fabrics stops soil, reduces the soil erosion of the second planting soil layer.
The utility model is further arranged to：Support frame as described above includes the support plate being placed on the non-woven fabrics, fixation
It is connected to foam-rubber cushion of the support plate far from second planting soil layer side.
By using above-mentioned technical proposal, the second planting soil layer of support plate pair is supported, and foam-rubber cushion plays the effect of buffering
Fruit can simultaneously absorb moisture, and salinity is made to be difficult to enter in the second planting soil layer, reduce the second planting soil layer salination
Probability.
The utility model is further arranged to：Several permeable holes are offered in the support plate, the permeable hole is along branch
The length direction of fagging is distributed, and crushed stone is placed in the permeable hole.
By using above-mentioned technical proposal, when rainwater flows in support plate, permeable hole in support plate by rainwater into
Row guiding, rainwater reach after crushed stone at foam-rubber cushion；When being oozed on salinity, since the gap between crushed stone is larger, salinity
It is difficult to ooze, converge at foam-rubber cushion, foam-rubber cushion is left under rain drop erosion later, reduce the salt marsh of the second planting soil layer
Change probability.
The utility model is further arranged to：Permeability cell, the week of the permeability cell are provided in second planting soil layer
Air hole is offered on the outer wall of side, the permeability cell is made of PVC.
By using above-mentioned technical proposal, the setting of permeability cell enables the root of plant preferably to be connect with air
It touches, the setting of air hole increases the contact area of permeability cell and the second planting soil layer, enhances air permeability effect, made of PVC
Permeability cell intensity is higher and more corrosion-resistant, makes permeability cell plant root can be helped to carry out in the second planting soil layer for a long time saturating
Gas.
The utility model is further arranged to：Water storage ring, the water storage ring are fixedly connected on the inner wall of the permeability cell
It is fixedly connected on the one end of the permeability cell far from second planting soil layer.
By using above-mentioned technical proposal, after moisture evaporation in the second planting soil layer, vapor is moved along permeability cell,
And water storage ring is touched, water storage ring makes vapor liquefy, and comes back in the second planting soil layer, reduces the amount for needing to water,
Water resource is saved.
In conclusion the utility model has the advantages that：
1, by the way that main line and secondary groove is arranged, so that moisture is left salt-soda soil from multi-direction, improve moisture and salt
Foundation area between alkali ground enables moisture to take away more salinity, reduces the salt concentration in salt-soda soil, reduces the upper of salinity
It oozes, improves the survival rate of trees；
2, by the way that separate layer and separation layer is arranged, salinity is made to be difficult to infiltrate into the second planting soil layer through capillary action, together
When do not influence whole drainage effect again, make the salinity in salt-soda soil be not easy to ooze while so that extraneous moisture is washed away salt-soda soil
Thoroughly in the second planting soil layer, the probability of the second planting soil layer salinization of soil is reduced, trees in the second planting soil layer are improved
Survival rate.
