Description
Technical field
The utility model relates to landscape engineering technology, on saline land, particularly plant the system of trees.
Background technology
The salinization of soil and Secondary Saline problem worldwide extensively exist, China saline land is large in number and widely distributed, widely distributed, and type is various, only modern salinization soil area about 3693.3 ten thousand hm2, remaining salinization soil about 4486.7 ten thousand hm2, potential salinization soil is 1733.3 ten thousand hm2, and all kinds of saline lands area amounts to 9913.3 ten thousand hm2, in arid, the semiarid zone in China northeast, northwest, North China, precipitation is little, and evaporation discharge is large, and the salinity be dissolved in water easily gathers at upper soll layer.Summer rainwater is many and concentrated, and great amount of soluble salt is seeped into lower floor with water or flows away, and Here it is " desalination " season; Spring, evaporation from topsoil was strong, and the salinity in underground water rises with capillary water and is gathered in upper soll layer, and this is main " accumulation of salt in the surface soil " season.
It is saline land that a lot of city increases land used newly, and salt content is higher, is unfavorable for plant growth, and carrying out urban road afforestation must first administer.The current way having occurred some anti-salt, text CN 20290727 U as open in Chinese utility model patent discloses a kind of salt discharge afforestation equipment, comprise sand stone layer, paving improvement soil layer above sand stone layer, establish permeable membrane between improvement soil layer and sand stone layer, in the saline land below sand stone layer, be provided with salt discharging pipe.This mode needs to lay permeable membrane, and permeable membrane cost is higher, is easily destroyed, and after discarded, easy contaminated environment, is arranged on salt discharging pipe in saline and alkaline soil layer, salt discharge poor effect.
Through statistics under the similar geological conditions in the whole nation, after taking general salt discharge alkali construction technology, the disposable survival rate mean value of large area saline land greening plantation nursery stock is only 85%.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of low cost and the drainage flexible pipe salt discharge of salt discharge better effects and if the anti-salt system of separation layer, makes the survival rate of urban tree to requiring.
For solving the problems of the technologies described above, drainage flexible pipe of the present utility model salt discharge and the anti-salt system of separation layer, be included in the raceway groove that saline land is excavated, coarse sands layer is filled out in the bottom surface of raceway groove, Permeable blind pipe is buried underground in coarse sands layer, lay metalling above coarse sands layer, above metalling, lay straw layer, above straw layer, lay composite soil and planting soil.Permeable blind pipe is embedded in coarse sands layer, and the saline-alkali water that infiltration can be made to rise to coarse sands layer enters Permeable blind pipe, and can not continue the pollution planting soil that rises.Lay metalling above coarse sands layer, can effectively prevent saline-alkali water from permeating, make saline-alkali water away from planting soil.Metalling lays straw layer, can prevent saline-alkali water from permeating further, can prevent again planting soil from draining in metalling along with rainwater, after straw is rotten, can also nutriment be become.
Further, described Permeable blind pipe and ground are the inclination angle of 10 degree to 15 degree.Can corresponding angle of inclination be set according to actual needs, so that the salt solution entering Permeable blind pipe can Self-discharged.
Improve as one, the sidewall of described raceway groove is arranged rubble cage, rubble cage, built with rubble, lays straw layer inside rubble cage.Trench sidewalls arranges metalling can effectively prevent the saline-alkali water of periphery from permeating to planting soil, and being placed on by rubble in rubble cage can convenient construction, prevents rubble from caving in.
Improve as one, in described rubble cage, be provided with Permeable blind pipe.In rubble cage, be also provided with Permeable blind pipe, in time the saline-alkali water of coming can be permeated in raceway groove both sides and drain in time.
After adopting such structure, carry out the construction of salt discharge alkali, speed is fast, effective, and can prevent soil from reappearing general saline and alkaline situation, be that trees surviving rate improves greatly.Lay flexible porous tube, making rubble, coarse sand, straw etc., method is simple, and speed of application is fast.The quality of construction quality, it is convenient to check, easily corrects.
Ecological benefits aspect, flexible porous tube, rubble, coarse sand, straw can not pollute planting soil, and straw layer can increase the fertility of soil.Transform saline land, make this plot plant greening, improve ecotope, suitable people live, and have saved land resources.
Economic benefit aspect, carries out the construction of salt discharge alkali by this engineering method, compared with the method such as other chemical modifying, physically improved, water conservancy improvement, its construction period is short, and construction method is simple, clean during construction.Surrounding environment is not polluted.Under the prerequisite reaching same salt discharge alkali effect, material price is cheap.
accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the first embodiment of the utility model.
Fig. 2 is the structural representation of the second embodiment of the present utility model.
Embodiment
As shown in Figure 1, drainage flexible pipe of the present utility model salt discharge and the anti-salt system of separation layer, be included in the raceway groove that saline land 7 is excavated, the bottom surface of raceway groove is filled out coarse sands layer 1, Permeable blind pipe 2 is buried underground in coarse sands layer 1, coarse sands layer 1 lays metalling 3 above, lays straw layer 4, lay composite soil and planting soil 5 above straw layer 4 above metalling 3.Permeable blind pipe 2 is embedded in coarse sands layer 1, and the saline-alkali water that infiltration can be made to rise to coarse sands layer 1 enters Permeable blind pipe 2, and can not continue the pollution planting soil that rises.Lay metalling 3 above coarse sands layer, can effectively prevent saline-alkali water from permeating, make saline-alkali water away from planting soil 5.Metalling 3 is laid straw layer 4, can prevent saline-alkali water from permeating further, can prevent again planting soil 5 from draining in metalling 3 along with rainwater, after straw is rotten, can also nutriment be become.Permeable blind pipe 2 can be the inclination angle of 10 degree to 15 degree with ground.Can corresponding angle of inclination be set according to actual needs, so that the salt solution entering Permeable blind pipe can Self-discharged.
