Abstract
The invention discloses a soil structure of an improved salt-affected soil, which comprises a soil surface layer, a soil bottom layer, a sand inclusion layer, a permeable layer and a waterproof layer, wherein the sand inclusion layer is positioned between the soil surface layer and the soil bottom layer, the permeable layer is arranged between the sand inclusion layer and the soil surface layer, the waterproof layer is arranged between the sand inclusion layer and the soil bottom layer, and a water draining tube stack is arranged in the sand inclusion layer. Through the method, the soil structure of the improved salt-affected soil can improve the soil quality, reduces environmental pollution and is convenient for comprehensive treatment.
Description
Technical field
The present invention relates to the soil melioration field, particularly relate to a kind of soil structure of improveing salt-affected soil.
Background technology
Along with developing rapidly of Chinese national economy and improving constantly of living standards of the people, the fast development of greening landscape construction, particularly coastal area of ecological garden building formula require more urgent.And be located in both urban and rural area on the saline land, and because the soil salt content height, salination is comparatively serious, and degree of mineralization of ground water height is difficult to utilize, and ornamental plant can not grow; Thereby, the vegetation construction difficulty, saline land afforestation construction difficulty is very big, and fund input is big, is the key factor of restriction saline soil district's ecological construction.At present, make up the garden structure ecoscape in the saline soil district, mainly adopt the integral replacing soil moved in to improve the original, soil moved in to improve the original is raised ground, hidden pipe salt discharge, the soil improvement method of zanjon salt discharge.Adopt common replacing soil moved in to improve the original, hidden pipe salt discharge technical method, except the arable land that takies homalographic, only the land consolidation project cost of green land lower part is general just be 60-120 unit/square metre, and brackish water discharge water outlet is underground pipe network or surrounding environment soil, like this, change soil moved in to improve the original because said method exists, taken the arable land, the engineering cost height, easily cause secondary environmental pollution, be unfavorable for the comprehensive regulation.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of soil structure of improveing salt-affected soil, can improve soil quality, reduces environmental pollution, is convenient to the comprehensive regulation.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of soil structure of improveing salt-affected soil is provided, comprise: upper soll layer, soil bottom, burning into sand layer, pervious bed and watertight composition, described burning into sand layer is between upper soll layer and soil bottom, be provided with pervious bed between described burning into sand layer and the upper soll layer, be provided with watertight composition between described burning into sand layer and the soil bottom, be provided with the drainpipe group in the described burning into sand layer.
In a preferred embodiment of the present invention, described drainpipe group comprises that a plurality of drainpipes are arranged in order and forms, and is arranged at burning into sand layer inside.
In a preferred embodiment of the present invention, be arranged in parallel between the described drainpipe, described drainpipe is provided with a plurality of apopores, and described drainpipe outside is coated with gauze layer.
In a preferred embodiment of the present invention, the thickness of described upper soll layer is 30-100cm, and the thickness of described soil bottom is 50-150cm.
In a preferred embodiment of the present invention, the thickness of described pervious bed is 1-5cm, and the thickness of described watertight composition is 2-8cm, and the thickness of described burning into sand layer is 15-30cm.
The invention has the beneficial effects as follows: the present invention improves the soil structure of salt-affected soil, can improve soil quality, reduces environmental pollution, is convenient to the comprehensive regulation.
Description of drawings
Fig. 1 is the structural representation that the present invention improves soil structure one preferred embodiment of salt-affected soil;
The mark of each parts is as follows in the accompanying drawing: 1, upper soll layer, 2, the soil bottom, 3, the burning into sand layer, 4, pervious bed, 5, watertight composition, 6, the drainpipe group.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, a kind of soil structure of improveing salt-affected soil, comprise: upper soll layer 1, soil bottom 2, burning into sand layer 3, pervious bed 4 and watertight composition 5, described burning into sand layer 3 is between upper soll layer 1 and soil bottom 2, be provided with pervious bed 4 between described burning into sand layer and 3 upper soll layers 1, be provided with watertight composition 4 between described burning into sand layer 3 and the soil bottom 2, be provided with drainpipe group 6 in the described burning into sand layer 3.
In addition, described drainpipe group 6 comprises that a plurality of drainpipes are arranged in order and forms, and is arranged at burning into sand layer 3 inside.
In addition, be arranged in parallel between the described drainpipe, described drainpipe is provided with a plurality of apopores, and described drainpipe outside is coated with gauze layer.
In addition, the thickness of described upper soll layer 1 is 30-100cm, and the thickness of described soil bottom 2 is 50-150cm.
In addition, the thickness of described pervious bed 4 is 1-5cm, and the thickness of described watertight composition 5 is 2-8cm, and the thickness of described burning into sand layer 3 is 15-30cm.
Be different from prior art, the present invention improves the soil structure of salt-affected soil, can improve soil quality, reduces environmental pollution, is convenient to the comprehensive regulation.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
