As follows to the detailed description of the invention below in conjunction with drawings and Examples:
To shown in Figure 9, be the method flow schematic diagram of specifically embodiment as Fig. 1.
In the land readjustment process, the principle of the new process basis of topsoil stripping " segmentation is peeled off, height is smooth, be close to backfill ", concrete stripping means and step are as follows:
A, the field of table soil to be stripped is divided into some bands, first band topsoil stripping is deposited, and is piled up in field outer a certain place---and the table mound is put the place, storage, maintenance, management; First band after peeling off is carried out land readjustment;
B, the table of inferior band soil piecemeal is stripped to first band after smooth, simultaneously the inferior band without table soil is divided into " taking the district " and " filling area ", and to set up the ridge, little field (soil) be that the border is so that filling; Soil layer is divided into two-layer: topsoil (top 20~40cm) and bottom soil layer X; Carry out smoothly according to the topsoil stripping principle of " delamination, backfill successively ", will take that the district reduces, the filling area raises, make the field face reach designed elevation after smooth;
C, (the 3rd) the band piecemeal topsoil stripping that will be close to are backfilling into the rational thickness of surface soil on district and filling area that takes of inferior band after smooth, simultaneously this band (the 3rd band) are carried out land readjustment, reach designed elevation after smooth;
D, the like, the last band of the table earthen backfill of at last first band being peeled off after smooth reaches designed elevation, completes topsoil stripping and the land readjustment work of whole field.
Principle of the present invention is:
In same smooth field scope, from the angle of economic benefit, land readjustment should be deferred to nearby principle, and topsoil stripping is as a procedure of land leveling project, and nearby principle is its key especially, embodies economy and the high efficiency of its construction.the new technology of topsoil stripping is mainly so that " segmentation is peeled off, height is smooth, contiguous backfill " the Soil Reconstruction principle be foundation, the field that namely will carry out topsoil stripping is divided into some bands according to the strip width that designs, with the unified zone of selecting that is deposited into after first band topsoil stripping temporarily, complete the native preservation work of table (after smooth as last band backfill table soil) and to the first band after topsoil stripping, be pushed into low plot with the soil of band by high-land and carry out land readjustment, then the table soil with adjacent ribbons (the second band) is backfilling into first band according to contiguous principle piecemeal, the like.
The concrete mathematical model of implementing is:
The topsoil that i piece segment table soil=(i+1) piece section is peeled off, wherein, i=1,2 ..., the piece hop count of n(n for dividing);
The topsoil that bottom soil layer (part)+(i+1) piece section is peeled off of the bottom soil layer of i piece section soil profile=i piece section+i ' piece section;
The topsoil that bottom soil layer (part)+(i+1) ' the piece section of i ' piece section soil profile=i ' piece section is peeled off;
N piece table soil=first band table mound is put the unsoil layer at place;
The bottom soil layer (part) of the bottom soil layer of n piece section soil profile=n piece section+n ' piece section+table mound is put the unsoil layer at place;
The bottom soil layer (part) of n ' piece section soil profile=n ' piece section+table mound is put the unsoil layer at place;
Annotate: the table mound place of putting is for depositing " taking district " the 1st section and " filling area " the 1st ' table of piece section is native.
When the technique to topsoil stripping designs, should fully take into account easy and operability that technique realizes.In the land control engineering, the principle that enforcement topsoil stripping technique should be followed mainly comprises:
(1) thickness of topsoil stripping is moderate, should not cross shallowly or excessively dark, avoids waste.According to soil reality and construction experience, general topsoil cover thickness of ploughing is in 20~30cm scope.But also should be in conjunction with the actual conditions at scene, because amount of cure and cross-section structure according to soil, the topsoil content of organic matter can reduce along with the increase of thickness, when being peeled off, the topsoil of paddy soil is no more than 40cm, and should and surpass bottom topsoil pile up separately, the use of 10cm with the plow layer of topsoil top 10cm, thereby reach the maximization that topsoil utilizes benefit.
(2) after the table earthen backfill, surface slope keeps in the reasonable scope, avoids the generation of local seeping phenomenon.Carry out backfill after topsoil stripping, also be equivalent to external soil moved in to improve the original, can cause settling amount to a certain degree after earthing, therefore need to guarantee the surface slope that forms after backfill be no more than 2 ° comparatively suitable, so just can not destroy the ventilative and water retention property of new formation table soil, guarantee that atmospheric precipitation is in the even distribution on earth's surface.
(3) the table mound of peeling off is put the place can not be too high, answers layering to stack.Choose suitable place and stack the table soil of peeling off, stack highly generally in the 5m left and right better, the highlyest should not surpass 10m, the stacking order is plow layer, tillage pan and subsoil layering from top to bottom stacking according to the soil structure level, if but the conditions permit layering deposit separately.The table mound is put the field and should be carried out compacting, take corresponding safeguard procedures, prevents from showing weathering and the water and soil loss of soil resource.
(4) the his-and-hers watches mound is put the field and is carried out the fertilizer conservation processing of fostering and apply fertilizer, and strengthens management.Before the table soil that is stripped from recycles, a table soil surface of answering that the his-and-hers watches mound puts the management of fostering and apply fertilizer, plantation organic crops plant, and regularly water, prevent from showing native arid, weathering.
(5) the plot management after the earthen backfill of reinforcement table.New topsoil soil structure after earthing is more fragile, strengthen preserve moisture and fertility management is carried out in the plot after backfill, in time is used, and avoids laying idle idle, the table soil of peeling off after recycling is returned to as early as possible or higher than the level of the productive forces before regulation.
Example:
(1) field with table soil to be stripped is divided into 4 bands, and the 1st band is divided into " filling area " and " taking the district " and sets up the ridge, little field (soil) is that the border is so that filling; With " filling area " the 1st section and " taking district " the 1st ' topsoil of piece section peels off, is stored in to show mound and put the place; Storage, maintenance, management; The 1st band after peeling off carried out land readjustment; Be divided into the 1st band soil layer two-layer: topsoil (top 20~40cm) and bottom soil layer X;
(2) then from " taking the district " the 1st ' the piece section extracts the bottom soil layer and is pushed into " filling area " the 1st section with bulldozer, makes both reach thick flat;
(3) again with the 2nd on the table soil of piece section and the 2nd section ' move to respectively the 1st ' piece section and the 1st section, carry out reaching designed elevation after smooth;
(4) according to the method for step 3, numbering repeats the process of topsoil stripping, soil-shifting, table earthen backfill in order, until complete the 3rd ' topsoil stripping and the land readjustment work of piece section and the 3rd section;
(5) with the 4th ' the bottom soil layer of piece section is pushed into " filling area " the 4th section with bulldozer, after completing thick putting down, the unsoil layer at the table mound place of putting on average is fills up to the 4th ' on piece section and the 4th section, reach designed elevation, complete topsoil stripping and the land readjustment work of whole field.
