Abstract
The utility model discloses a structure of improved salt-affected soil. The structure of the improved salt-affected soil comprises a soil surface layer, a soil bottom layer, a sand inclusion layer, a permeable layer and a waterproof layer, the sand inclusion layer is located between the soil surface layer and the soil bottom layer, the permeable layer is located 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 drain pipe set is arranged in the sand inclusion layer. Therefore, according to the structure of the improved salt-affected soil, soil quality can be improved, environment pollution is reduced, and comprehensive treatment is facilitated.
Description
Technical field
The utility model relates to soil melioration field, particularly relates 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 Afforestation Landscape of ecological garden building type is built fast development, particularly coastal area and is required more urgent.And be located in the both urban and rural area on saline land, and because soil salt content is high, salination is comparatively serious, and the degree of mineralization of ground water is high, is difficult to utilize, and ornamental plant can not grow; Thereby, vegetation construction difficulty, saline land Urban Landscape Construction difficulty is very large, and fund input is large, is the key factor of restriction Saline Soil Area ecological construction.At present, build garden structure ecoscape in Saline Soil Area, mainly adopt 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 taking the arable land of homalographic, only afforest the land consolidation project cost of under ground portion general just for 60-120 unit/square metre, and brackish water to discharge water out be underground pipe network or surrounding environment soil, like this, because said method exists, change soil moved in to improve the original, taken arable land, engineering cost is high, easily cause secondary environmental pollution, be unfavorable for the comprehensive regulation.
Utility model content
The technical problem that the utility model mainly solves is to provide 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 utility model 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, between described burning into sand layer and upper soll layer, be provided with pervious bed, between described burning into sand layer and soil bottom, be provided with watertight composition, in described burning into sand layer, be provided with drainpipe group.
In preferred embodiment of the utility model, described drainpipe group comprises that a plurality of drainpipes are arranged in order and forms, and it is inner to be arranged at burning into sand layer.
In preferred embodiment of the utility model, between described drainpipe, be arranged in parallel, on described drainpipe, be provided with a plurality of apopores, described drainpipe outside is coated with gauze layer.
In preferred embodiment of the utility model, the thickness of described upper soll layer is 30-100cm, and the thickness of described soil bottom is 50-150cm.
In preferred embodiment of the utility model, 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 beneficial effects of the utility model are: the soil structure of the utility model improvement salt-affected soil, can improve soil quality, and reduce environmental pollution, be convenient to the comprehensive regulation.
Accompanying drawing explanation
Fig. 1 is the structural representation of soil structure one preferred embodiment of the utility model improvement salt-affected soil;
In accompanying drawing, the mark of each parts is as follows: 1, upper soll layer, 2, soil bottom, 3, burning into sand layer, 4, pervious bed, 5, watertight composition, 6, drainpipe group.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to 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, between described burning into sand layer 3 and upper soll layer 1, be provided with pervious bed 4, between described burning into sand layer 3 and soil bottom 2, be provided with watertight composition 5, in described burning into sand layer 3, be provided with drainpipe group 6.
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, between described drainpipe, be arranged in parallel, be provided with a plurality of apopores on described drainpipe, 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 soil structure of the utility model improvement salt-affected soil, can improve soil quality, reduces environmental pollution, is convenient to the comprehensive regulation.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
