Abstract
The utility model relates to the technical field of soil improvement, particularly to a salt drainage pipe for soil improvement, which includes a compacted PVC water drain pipe embedded in a tunnel or a ditch, wherein a plurality of salt drainage holes are uniformly distributed on the pipe wall of the PVC water drain pipe; the total of the surface areas of the salt drainage holes is no less than the area of the pipe wall of the PVC water drain pipe; the salt drainage pipe also includes a geotextile covering layer covered on the outer wall of the PVC water drain pipe, and the water permeability of the geotextile covering layer is more than 10 times than that of the soil. The salt drainage pipe for soil improvement can fully utilize the groundwater capillary elevation mechanism, the saline and alkaline in the groundwater can permeate the salt drainage pipe and is naturally drained, the rain water and the irrigation water on the earth surface can dissolve the saline and alkaline and permeate the salt drainage pipe to be drained, and the water permeation quantity and the structural firmness of the PVC water drain pipe are ensured.
Description
Technical field
The utility model relates to agricultural gardening industrial field, relates in particular to a kind of salt discharge pipe that is used for soil conditioning.
Background technique
Mostly traditional salt affected soil improvement is that arranging measures such as alkali, big hydraulic pressure alkali, raised fields row alkali with the open drain carries out, row's alkali measure water consumption of this class is big, the water resource waste situation is serious, and, because phreatic reverse osmosis effect, when stopping to pour water, soil is easy to salinization of soil once more, makes that the cost of soil conditioning is too high.
Summary of the invention
At the deficiency of prior art scheme, the utility model proposes a kind of salt discharge pipe that is used for soil conditioning.
The technical solution adopted in the utility model is as follows:
A kind of salt discharge pipe that is used for soil conditioning, comprise: the caliber that is embedded in tunnel bottom of trench compacting is the PVC waste pipe, the tube wall of this PVC waste pipe is provided with equally distributed a plurality of salt discharges hole, the aperture surface area sum in this salt discharge hole is not less than 2% of PVC waste pipe tube wall area, be coated on the geotextiles clad of above-mentioned PVC waste pipe outer wall, the water permeability of this geotextiles clad is higher than soil water permeability more than ten times.
Further, the caliber of described PVC waste pipe is 160mm.The cross-section area in described salt discharge hole is 10mm
2-80mm
2
The utility model is by adopting technique scheme, and the beneficial effect that has is:
1. make full use of the mechanism that the underground water capillary rises, discharge naturally after saline and alkaline in the underground water infiltrated this salt discharge pipe, this salt discharge pipe discharge is infiltrated in the saline and alkaline back of the precipitation on the face of land and irrigation water solubilized, thus water saving, cost are low, the salt discharge effect reliably and with long-term;
2. salt discharge hole cross-section area adopts 10mm
2-80mm
2, guaranteed the permeable amount of PVC waste pipe and the robustness of structure.
Description of drawings
Fig. 1 is the cross-section schematic representation of the utility model salt discharge pipe.
Fig. 2 is the longitudinal section schematic representation of the utility model salt discharge pipe.
Embodiment
Now with embodiment the utility model is further specified in conjunction with the accompanying drawings.
A kind of salt discharge pipe that is used for soil conditioning, comprise: the caliber that is embedded in tunnel bottom of trench compacting is a PVC waste pipe 1, the tube wall of this PVC waste pipe 1 is provided with equally distributed a plurality of salt discharges hole 2, the aperture surface area sum in this salt discharge hole 2 be not less than PVC waste pipe 1 tube wall area 2%, be coated on the geotextiles clad 3 of above-mentioned PVC waste pipe 1 outer wall, the water permeability of this geotextiles clad 3 is higher than soil water permeability more than ten times.
Preferably, the caliber of described PVC waste pipe 1 is 160mm.And the cross-section area in described salt discharge hole 2 is 10mm
2-80mm
2For the circulation of the current that guarantee PVC waste pipe 1, should adopt the pvc pipe of more suitable caliber.At this moment, the cross-section area in the salt discharge hole 2 that distributes on the PVC waste pipe 1 10mm preferably
2-80mm
2The aperture in such salt discharge hole can guarantee that PVC waste pipe 1 at the ground pressure that bears compacting pipeline deformation does not take place, guarantee under the reliable prerequisite of pipeline configuration the saline and alkaline of soil to be infiltrated in this salt discharge pipe apace, and be difficult for the crystallization hardening and stop up salt discharge hole 2.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in the spirit and scope of the present utility model that do not break away from appended claims and limited; can make various variations to the utility model in the form and details, be protection domain of the present utility model.
Claims (3)
1. salt discharge pipe that is used for soil conditioning, it is characterized in that: comprising: the PVC waste pipe that is embedded in tunnel bottom of trench compacting, the tube wall of this PVC waste pipe is provided with equally distributed a plurality of salt discharges hole, the aperture surface area sum in this salt discharge hole is not less than 2% of PVC waste pipe tube wall area, is coated on the geotextiles clad of above-mentioned PVC waste pipe outer wall.
2. the salt discharge pipe that is used for soil conditioning as claimed in claim 1, it is characterized in that: the caliber of described PVC waste pipe is 160mm.
3. the salt discharge pipe that is used for soil conditioning as claimed in claim 1 is characterized in that: the cross-section area in described salt discharge hole is 10mm
2-80mm
