Description
Technical field
The present invention relates to pit reparative regeneration field more particularly to a kind of discarded pits based on architecture sediment filling engineering
Reclamation method.
Background technique
In recent years as the sharp increase of ore extraction amount leaves a large amount of outdoor discarded pits, over time, give up
Water can be full of in barrow hole, these water-filled discarded pits are generally used to carry out fishery cultivating, but China's cultivated land resource is tight
, these discarded pits are used to carry out fishery cultivating to be a kind of huge waste.
Annual urban construction project can all generate a large amount of architecture sediment, architecture sediment main component be brick, concrete block,
Soil and a small amount of reinforcing bar, wherein most important or brick is with concrete block, at present for the main application of architecture sediment
Still it is used as the ballast aggregate repaired the roads, but the architecture sediment for consumption of repairing the roads is extremely limited, more architecture sediments are still worked as
Outskirts of a town have been poured into as building waste.Architecture sediment is poured into outskirts of a town and wastes vast resources, more occupies a large amount of plough
Ground.
Based on above-mentioned thinking, the present invention provides a kind of method that the pit for carrying out soil remodeling based on architecture sediment is repaired.
Summary of the invention
The present invention is in view of the above-mentioned problems, propose a kind of discarded pit reclamation method based on architecture sediment filling engineering.
The technical solution adopted by the present invention is as follows:
A kind of discarded pit reclamation method based on architecture sediment filling engineering, includes the following steps:
S1: hard pipe is protruded into the hole bottom in pit, and passes through the pipe constantly air-blowing into pit；
S2: while through the pipe air-blowing into pit on one side, architecture sediment is toppled over into pit on one side, when in pit
The moisture content of sludge stop toppling over architecture sediment when being down to 60%；
S3: further into sludge, air-blowing stops air-blowing after the moisture content of sludge is down to 30%；
S4: pouring into the broken foam of stalk, fruits and vegetables residue and feces of livestock and poultry into sludge, and makes to maintain three's temperature 25 DEG C~40
Ferment 240h~280h at DEG C；
S5: soil is toppled in the top of fermentation residue.
Because being filled with water in pit, architecture sediment is toppled over while the air-blowing into pit following beneficial effect:
1, gas can constantly emit upwards from the hole bottom in pit, and gas will constantly leave out of pit, and gas
Body leaves from pit can take away certain moisture, can thus accelerate the evaporation rate of water, accelerate the dry speed in pit；
2, because the main brick of ingredient, concrete block, soil and a small amount of reinforcing bar of architecture sediment, are poured into architecture sediment
During in pit, four density soil is most light and is that can uniquely be dissolved in water, and is fallen together when four
When in water inlet, brick, concrete block and reinforcing bar are since autologous density is larger, and air-flow, which can not be blown, floats to the surface place, so brick
Block, concrete block and reinforcing bar, which are understood, oneself is deposited to pit bottom, and soil is due to being dissolved in water, in air-flow in the effect of blowing floating
Under, it will not be accumulated in pit bottom；
3, architecture sediment is toppled over while ventilating can make the mud in pit be uniform and stable, be not in differential settlement
Different phenomenon.
When the water content of mud is down to 60% stop topple over architecture sediment be because this when mud concentration compared with
Height, viscosity is larger, and architecture sediment, some small volumes and the lesser small brick of density and small concrete are toppled over while ventilating
Block can't sink under pit, and can due to mud viscosity and air-flow on the effect of blowing, be suspended in the surface of mud, be
It avoids below this farmland reclaimed or arable land surface soil without these small concrete blocks and small brick, in the aqueous of mud
Amount is down to 60% stopping and topples over architecture sediment.
Further air-blowing is to work as mud to accelerate mud and dry up during mud water content is down to 30% by 60%
Water content be down to 30%, be actually mud, be no longer mud.It will appear sedimentation during this, relatively
In sedimentation under natural conditions, air-flow can be taken away in lower layer's mud during from pit bottom to mud surface motions
Moisture can accelerate the dry and sedimentation of lower layer's mud in this way.
When mud water content is down to 30%, it is put into ferments into the broken foam of stalk, fruits and vegetables residue and feces of livestock and poultry at this time
Organic fertilizer is prepared, the laborious of soil is improved, is built up fertility for farming crops.Because being actually mud, topple over
The broken foam of stalk, fruits and vegetables residue and feces of livestock and poultry on mud can all stay in the surface of mud substantially, and maintaining fermentation temperature is 10 DEG C
First~40 DEG C are to be able to fermentative degradation organic matter quickly, be second the volatilization in order to accelerate the moisture in mud.
After the fermentation has been completed, then on the surface of mud topple one layer of soil, the water content of this soil to topple how many,
The rear of soil depends entirely on the purposes in the pit after reclaiming at there is mostly thickness, as being used as paddy field or farmland after reclaiming,
The soil water content and soil dosage toppled needed for the two purposes are different.
In the present solution, repair pit using the method for architecture sediment combination air-blowing, the pit after reclaiming can be with
As paddy field, perhaps farmland and the paddy field reclaimed via pit or farmland soil fertility content are high.
Optionally, the temperature for the gas that the pipe blasts is 30 DEG C~40 DEG C.
Take this temperature and have following two the utility model has the advantages that
1, because being containing aquatic animals such as more fish, shrimps in the water in pit, and the animals such as fishes and shrimps are toppling over building slag
All dead in the process of soil, the gas for being passed through 30 DEG C~40 DEG C temperature can accelerate the activity of microorganism in water, can accelerate
The corpse of fishes and shrimps decomposes, and fishes and shrimps corpse is decomposed to obtain fertilizer and can be dissolved in mud, improves the fertility of mud；
2, above-mentioned temperature can accelerate the dry speed of mud.
Optionally, the broken foam of the stalk, fruits and vegetables residue and the mass ratio of feces of livestock and poultry three are 3:3:1.
Said ratio only has more excellent proportion.
The beneficial effects of the present invention are: pit is repaired using the method for architecture sediment combination air-blowing, after reclaiming
Pit may be used as paddy field, and perhaps farmland and the paddy field reclaimed via pit or farmland soil fertility content are high.
Specific embodiment:
Below with reference to each case study on implementation, the present invention will be described in detail.
Case study on implementation 1
Implement ground: pit is discarded in Zhejiang Deqing County；Pit situation: outdoor, bosom 45m is deep, and most shallow place is apart from ground
2m, area of the pit bottom most portion at earth's surface about 20m~30m, earth's surface are 2.27 hectares, are implemented the time started 2011
It repairs Secondary Reclamation Time in June, 2013 in May, is paddy field entirely around pit.
The preparation stage is repaired, pavement is built above pit, laying pipeline builds conveyer belt.
The first stage is repaired, gas is heated to 30 DEG C~40 DEG C using air blower and heat exchanger and (is amounted to by pipe
1007 root canals, pipe is steel pipe, and the caliber of pipe is 50cm~60cm) by gas drum into the bottom in pit, gas is from pit
Bottom constantly emits up, will topple over architecture sediment in pit by conveyer belt, air-blowings on one side topple over architecture sediment while, not
The water content of disconnected detection mud, when being entirely substantially water in pit, the outlet speed for controlling every root canal is 3m2/ s, works as beginning
When toppling over architecture sediment, the outlet speed of every root canal is gradually decreased, and appropriate adjustment architecture sediment launches speed.
Second stage is repaired, the water in pit gradually becomes mud, and the liquid level of mud is close to earth's surface, the water content of mud
It is 60% or so, stops launching architecture sediment at this time, the outlet speed for adjusting every root canal is 1m2/ s, and with this gas speed
Degree is blown to the water content of mud and is down to 30%, and mud has changed into mud at this time, stops air-blowing at this time, using crane by pipe from
It is extracted in mud, enables mud is dry in its natural state to settle a period of time, when opening when being settled down to apart from earth's surface about 1m for mud
Beginning next step repair, the time for completing second stage is in March, 2012.
The phase III is repaired, topples over mud after straw disintegrating slag, green vegetable leaf and chicken and duck excrement are mixed in the ratio of 3:3:1
Surface, fermentation material with a thickness of 10cm, ferment under open-air atmosphere, under daytime sunshine state, the temperature of fermentation material may be up to 40 DEG C,
Night temperatures are lower to be kept the temperature fermentation material in fermentation material surface capping straw mattress, and second day sunrise time-division took away straw mattress again,
This process maintain 20 days, if encounter have more rainy weather number of days it is more when, be appropriately extended fermentation time.It ferments this mistake
Mud in journey in pit understands oneself, and further sedimentation is dry.
Fourth stage is repaired, because pit is nearby paddy field thus, so this pit, which is used as paddy field after repairing, carrys out rice cultivation,
So this stage topples over damp soil in pit, and removes the equipment such as pavement and conveyer belt, it will be wet using cultivator
The Soil and Fertilizer of profit is sufficiently mixed, and when with cultivator mixed soil and fertilizer, soil is continuously replenished, so that pit
Surface is concordant with earth's surface.It completes this wheel and repairs in June, 12.Pit, which is repaired, at this time completes, but pit can not also carry out at this time
Crop cultivation, because still there is gap between brick and concrete block at this time, soil can still be infiltered, the soil on pit surface
Earth still will appear biggish sedimentation, if being used directly to rice cultivation at this time, it may appear that cause rice dead because of impeded drainage
It is in poor harvest.So complete the First Year not rice cultivation after repairing, its natural subsidence 1 year again is allowed.
After natural subsidence 1 year, soil, the mud on pit surface are filled with substantially in brick and concrete block in pit
Soil will not settle again substantially, after one layer of damp soil is padded on surface again, so that the soil face in pit and earth's surface are close flat
It together, can rice cultivation.
Case study on implementation 2
Implement ground: Meishan, changxing, zhejiang Province county discards pit；Pit situation: outdoor, bosom 42m is deep, and most shallow place is apart from ground
2m, area of the pit bottom most portion at earth's surface about 25m or so, earth's surface are 3.27 hectares, are implemented the time started 2012 years 7
Month, it repairs Secondary Reclamation Time in October, 2013, is nursery stock base entirely around pit.
The preparation stage is repaired, pavement is built above pit, laying pipeline builds conveyer belt.
The first stage is repaired, gas is heated to 30 DEG C~40 DEG C using air blower and heat exchanger and (is amounted to by pipe
2000 root canals, pipe is steel pipe, and the caliber of pipe is 50cm~60cm) by gas drum into the bottom in pit, gas is from pit
Bottom constantly emits up, will topple over architecture sediment in pit by conveyer belt, air-blowings on one side topple over architecture sediment while, not
The water content of disconnected detection mud, when being entirely substantially water in pit, the outlet speed for controlling every root canal is 3m2/ s, works as beginning
When toppling over architecture sediment, the outlet speed of every root canal is gradually decreased, and appropriate adjustment architecture sediment launches speed.
Second stage is repaired, the water in pit gradually becomes mud, and the liquid level of mud is close to earth's surface, the water content of mud
It is 60% or so, stops launching architecture sediment at this time, the outlet speed for adjusting every root canal is 1m2/ s, and with this gas speed
Degree is blown to the water content of mud and is down to 30%, and mud has changed into mud at this time, stops air-blowing at this time, using crane by pipe from
It is extracted in mud, the time for completing second stage is in January, 2013.
The phase III is repaired, because January, temperature was too low, fermenting speed is slow, so after completing second stage and repairing, first
Stack one layer of dry soil again in muck surface, by pit surface it is padded at earth's surface 0.4m, it is dry to its natural subsidence
It ferments again after dry 4 months.Into after May, straw disintegrating slag, green vegetable leaf and chicken and duck excrement are mixed in the ratio of 3:3:1
After topple over mud surface, fermentation material with a thickness of 10cm, ferment under open-air atmosphere, under daytime sunshine state, the temperature of fermentation material
Up to 50 DEG C, to avoid excessive temperature from causing microorganism dead, one is spilt to fermentation material every 3~4 hours under daytime sunshine
Secondary cold water, this process maintain 20 days, and May is still higher than 10 degree rainy weather temperature, so without being kept the temperature
Processing extends fermentation time.
Fourth stage is repaired, because the June and July after May are the traditional plum rain seasons in Jiangnan, rainfall may consequently contribute to mine
The further sedimentation of soil in cheating, so the soil natural in pit is allowed to settle in June and July 2 months.
Repaired for the 5th stage, because pit is nearby nursery stock base thus, so this pit is used as farmland after repairing to plant
Vegetables utilize cultivator so this stage topples over damp soil in pit, and removes the equipment such as pavement and conveyer belt
Damp soil and fertilizer are sufficiently mixed, and when with cultivator mixed soil and fertilizer, soil is continuously replenished, so that mine
The surface in hole is concordant with earth's surface.Using August and the xeothermic feature short of rain of September, soil is allowed to dry out, completed at this time to soil
It repairs, because having already passed through the natural subsidence close to 5 months at this time, significantly sinking can further occur in the soil on pit surface
Drop, and entering after October to June next year is all precipitation less season, is not in waterlogging phenomenon in pit, so the year
October is used to planting vegetable.
Growth characteristics based on seasonal characteristic and various vegetables, potato, celery in the case where being sowed in pit October current year
And radish.
Into after in September, 14, because soil will appear a small amount of sedimentation, in order to plant a greater variety of crops, because
This fills out one layer of soil into pit again, that is, is properly completed reparation.
The above description is only a preferred embodiment of the present invention, not thereby limits scope of patent protection of the invention, all
It is directly or indirectly to be used in other related technical areas, together with Structural Transformation made by present specification
Reason includes within the scope of the present invention.
