Abstract
The utility model discloses an utilize structure in building rubbish improvement saline and alkaline land comprises from supreme down following layer in proper order: the former layer in saline and alkaline land, geosynthetic material keep apart, filter bottom, building rubbish layer, geosynthetic material isolation, filter top layer, saline -alkali soil coating, still include the sump pit, the vertical setting of sump pit to pass building rubbish layer, geosynthetic material isolation, filter top layer, saline -alkali soil coating. The utility model discloses an utilize structure in building rubbish improvement saline and alkaline land utilizes the building rubbish that city management person is very thorny to solve outstanding factor - the saline and alkaline land problem that perplexs rural economic development.
Description
Technical field
the utility model relates to alkaline land improvement technical field, specifically a kind of structure utilizing building waste to improve saline land.
Background technology
China is the maximum country of world's new building last year amount, annual 2000000000 m
2newly-built area, consumes the cement in the whole world about 50%, iron ore, coal.And average " life-span " of building only has 25 ~ 30 years, building waste has accounted for 30% ~ 40% of rubbish total amount, just with the etch of ten thousand tons the environment that we depend on for existence in every number of days, people, while enjoyment urban civilization, also suffer from " garbage-surrounded city ", the puzzlement of " haze shrouds " and injury.The process of building waste has become city manager's very stubborn problem.On the other hand, there is wide littoral zone in China, littoral zone periphery have a large amount of in heavy salinized ground resource, along with environment change, rainfall reduce, saline Land is on the rise, become puzzlement local rural economic development outstanding factor.One of major measure of current Saline-alkali Field Control raises face, field, utilizes natural precipitation or irrigation to discharge saline and alkaline.And improve face, field and need a large amount of environmentally conscious materials.
Utility model content
in order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of structure utilizing building waste to improve saline land, be made up of successively from bottom to up following layers: the isolation of the former layer in saline land, geosynthetics, filtration bottom, building waste layer, geosynthetics isolation, filtration top layer, saline-alkali soil coating, also comprise sump, sump is vertically arranged, and through building waste layer, geosynthetics isolation, filtration top layer, saline-alkali soil coating.
The building waste that utilizes of the present utility model improves the structure in saline land, is the outstanding factor-saline land problem utilizing the very thorny building waste of city manager to solve to trouble rural economic development.
Accompanying drawing explanation
fig. 1 is a kind of generalized section utilizing building waste to improve the structure in saline land;
Fig. 2 is this system sump position plane schematic diagram;
Fig. 3 is the enforcement generalized section of this structure.
Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-3, the structure utilizing building waste to improve saline land of the present utility model is isolated by the former layer 1 in saline land, the geosynthetics of not easily degrading, filters bottom 2, slightly isolates through the building waste layer (rejecting harmful substance) 3 of sorting, the geosynthetics of not easily degrading, is filtered top layer 4, saline-alkali soil coating 5, sump 6 form.
This structure builds in the following way:
One) the first width, is excavated; Excavated by the soil body of saline land about skin depth 1.5m (this degree of depth can meet most plant growth demand) with excavator, be placed on excavation width side, for reducing old, groove width can be determined by the excavator radius of clean-up.Bottom land need not stay slope, approximate horizontal; Lay the geosynthetics of not easily degrading to isolate, filter bottom; A sump is built within the specific limits by laying bricks or stones by designing requirement; Backfill is slightly through the building waste (its thickness can the building waste quantity of landfill, this face, field, improvement saline land, section of planning and designing are raised and highly determined as required) of sorting; Lay the geosynthetics of not easily degrading to isolate, filter top layer;
Two), the second width is excavated: the soil body excavated out is backfilling into geosynthetics isolation that the first width not easily degrades, filters above top layer, and cutting depth is identical with first, by that analogy.
When the structure utilizing building waste to improve saline land of the present utility model runs into rainfall or irrigates, fresh water infiltrates soil layer under Gravitative Loads, brings salt and alkali component in soil into building waste layer, is drained by sump.Geosynthetics plays isolation, filtration, can isolate the soil body and not be mixed into building waste layer, and can ensure that again in process of osmosis, soil particle is not brought into building waste layer, building waste layer remains water permeable ability smoothly.If Groundwater buried depth is more shallow, high salinity content water body more than building waste layer under Gravitative Loads under infilter into building waste layer, be discharged from sump subsequently, reach alkaline land improving object; Building waste layer following high salinity content underground water rises and enters building waste layer, is discharged subsequently, ensures modified soil not by salinization of soil again from sump.
Claims (1)
1. the structure utilizing building waste to improve saline land, be made up of successively from bottom to up following layers: the former layer in saline land (1), geosynthetics isolation, filtration bottom (2), building waste layer (3), geosynthetics isolation, filtration top layer (4), saline-alkali soil coating (5), it is characterized in that: also comprise sump (6), sump (6) is vertically arranged, and through building waste layer (3), geosynthetics isolation, filtration top layer (4), saline-alkali soil coating (5).
