Abstract
An ecological comprehensive treatment technology for coast reclamation dredger fill is disclosed, which comprises the following steps of: performing grooving and soil turning on the land needing to be reformed, and dividing the groove into a plurality of parallel sections at first; digging a main water-sprinkling blind ditch on the bottom of the groove along a depth direction, and connecting the main water-sprinkling blind ditch with a municipal water-draining well or water-draining ditch; digging a branch water-sprinkling blind ditch intersected with the main water-sprinkling blind ditch on the bottom of each section; filling ballast bags; paving an anticorrosive material among the branch water-sprinkling blind ditches; paving a water-sprinkling layer on the bottom of the groove, covering an anti-mud-seepage film, and paving an anti-lateral-seepage film; backfilling the mixed soil obtained after uniformly blending the groove soil turned out with blending substances; disposing a plurality of small square furrows on the levelled ground, drilling a plurality of sand holes on the small square furrows, and connecting the sand holes with the water-sprinkling layer; then irrigating; and finally applying an acidic improved fertilizer on the surface of the land, performing rotary tillage and blending. The ecological comprehensive treatment technology for coast reclamation dredger fill has the advantages of being capable of efficiently protecting cultivated land resource, simple and convenient in construction, low in investment cost, and capable of utilizing natural falling water for saving lots of fresh water resource.
Description
(1) technical field:
The present invention relates to a kind of coastal soil improvement method, especially a kind of extra large barged-in fill ecology synthesis improvement technology of enclosing.
(2) background technology:
Now solve the marine solonchak original soil basically and improved a difficult problem of doing greening; But the greening of newly enclosing extra large barged-in fill then is " global problem " of generally acknowledging in the world, because of the soil of new hydraulic reclamation not only salt content be higher than general marine solonchak, the interior water content of the soil body is higher simultaneously; It is a kind of soil body that does not form soil; Not only muddy, not penetrating, and the content of organic matter in the soil is extremely low, and " on the spot " condition of plant growing can only be provided.Therefore the difficulty of improvement is very large.
This technology has solved this " global problem " just, adopts and does not change planting soil to barged-in fill improvement and greening, has effectively protected cultivated land resource and ecotope, has promoted the sustainable development of resource and environment.
(3) summary of the invention:
The objective of the invention is to design a kind of extra large barged-in fill ecology synthesis improvement technology of enclosing, it can solve the deficiency that prior art exists, easy construction, and cost of investment is low; Can utilize natural rainfall, practice thrift a large amount of freshwater resources.
Technical scheme of the present invention: a kind of extra large barged-in fill ecology synthesis improvement technology of enclosing is characterized in that it may further comprise the steps:
(1) at first slots and dig, groove is divided into some locations that are parallel to each other along the depth direction of groove in the soil of needs transformation;
(2) dig along the depth direction in the bottom of groove and establish at least one main trickle french drain, main trickle french drain links to each other with municipal drainage well or drain ditch;
(3) dig in the bottom in each location and establish at least one trickle french drain that intersect with main trickle french drain;
(4) in a main trickle french drain and a trickle french drain, fill quarrel stone bag;
(5) between every trickle french drain, lay anti-corrosion material;
(6) lay the trickle layer in the bottom of groove, and cover anti-mud in the above and ooze film; And the good anti-side in shop, soil contact place with not improvement in improvement is oozed film;
(7) with the groove routed up soil with mix the composite soil after thing evenly mixes, be backfilling in the groove;
(8) on smooth good ground, make some little side's furrow, and on little side's furrow, beat some husky holes, husky hole and trickle layer join, and fill coarse sand or grain of rice stone in the husky hole; Water then;
(9) after the soil watered, execute acid improvement again on the surface, soil of being transformed fertile, carries out rotary tillage and mix.
The location width that is parallel to each other in the said step (1) is 10-20m.
In the said step (2) each bar master trickle french drain be spaced apart 100-200m, the specification of every main trickle french drain is 30*30cm.
Each bar props up the 3-6m that is spaced apart of trickle french drain in the said step (3), and the specification of every trickle french drain is 20*20cm.
Said main trickle french drain all has certain gradient with a trickle french drain.
The diameter of quarrel stone bag is 20-30cm in the said step (4), length 3m; The contact place of adjacent two quarrel stone bags is with a block length 0.9-1.3m, and the woven cloth of wide 30cm encases, and treats that ballast bag laying finishing back increases some ballasts in the not enough part of interface ballast, wraps with the woven cloth that sets in advance then that is:.
Anti-corrosion material in the said step (5) is an anti-rot plastic cloth.
Trickle layer in the said step (6) is little aggregate chips, and thickness is 3-5cm.
Mixing thing in the said step (7) is rice husk, crushing straw, wild vegetation, ashes, various plant species shell or house refuse, is that 20% ratio mixes according to volume ratio.
On smooth good ground, making some little side's furrow in the said step (8) is: the little side's furrow of every 5m*5m; Saidly on little side's furrow, beat some husky holes and be: whenever in every furrow make a call to a husky hole at a distance from 1m, the diameter in husky hole is 4-8cm.
Fill coarse sand or grain of rice stone in the said step (8) in the husky hole extremely apart from ground 30cm.
Said step (8) adopts disposable continuous pouring, and every square meter water consumption finally makes soil salt content reach below 0.3% at 0.6～0.8t.
Executing the fertile thickness of acid improvement on the surface, soil of being transformed in the said step (9) is 8-10cm; The degree of depth that said rotary tillage mixes is 30cm.
After said step (9) land reclamation finishes, carry out plant planting: plant pit is dug in the place needs plantation plant; Beat the trickle hole that direct and underground trickle layer links to each other at the center of plant pit; Shop coarse sand at the bottom of plant pit; Be placed on center position at the bottom of the plant pit to tree then, fill out coarse sand at the native ball and the position, space of hole wall then, the hole soil that digs out with plant pit is again carried out dash furrow low bank between fields around plant pit, carry out the big flood pouring, till irrigating.
The diameter of said plant pit is 10 times of the trunk diameters of plant, and native ball is 8 times of the trunk diameters of plant.
The trickle bore dia that said and underground trickle layer links to each other is 10cm; Fill coarse sand or grain of rice stone in the hole; The thickness of shop coarse sand is 10-15cm at the bottom of the said plant pit.
Superiority of the present invention and good effect: 1, do not change improvement and the greening that planting soil carries out barged-in fill, the resource of effectively protecting farmland; 2, easy construction, cost of investment is low; 3, high-intensity manual intervention makes barged-in fill within short-term, become the planting soil that satisfies plant growing condition; 4, can utilize natural rainfall, practice thrift a large amount of freshwater resources.
