Description
Technical field
The invention belongs to technical fields of reclaiming fields from the sea, and in particular to a kind of method in reclaiming land around sea domain.
Background technique
With the people's livelihood such as industry park, harbour, airport, power station building the development demand in seashore soil, especially population
Development, many countries need to want soil, that is, to reclaim fields from the sea to ocean.And enclose extra large reclamation by pumping filling can be the advantage of lower cost the case where
Under, problems of land utilization is solved, plays relaxation effect for alleviating economic development and the insufficient contradiction of construction land.Extra large hydraulic reclamation is enclosed to make
The major project content on ground is divided into two steps: first is that first enclosing sea builds embankment, second is that into embankment, hydraulic reclamation backfills to form land-based area again.
The method reclaimed fields from the sea common at present is to inhale the silt particle that ship deposits sea area beach with strand to pass through waterpower hydraulic reclamation extremely
Presumptive area forms warp.These barged-in fill concentration are low, water content is high, sewage is more, and environment is polluted in sewage discharge.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of method in reclaiming land around sea domain.
In order to achieve the above object, the invention is realized by the following technical scheme:
A kind of method in reclaiming land around sea domain, includes the following steps:
Step (1) is arranged embankment on the periphery that need to enclose sea region, has blockship cooperation in embankment, grab bucket is equipped on blockship
Machine and belt conveyor；
Step (2) grabs mud in the sea area that distance encloses sea region embankment periphery suitable distance using dredger, and shipping is extremely
Sea region is enclosed, close to blockship side；
Step (3), is grabbed to belt conveyor using the mud that the grab claw on blockship ships dredger, by belt
Land-based area backfill is carried out in the Belt Conveying to embankment of conveyer, mobile blockship is until form land-based area.
Preferred embodiment in accordance with the present invention, the embankment in step (1) are formed for segment sync.
Preferred embodiment in accordance with the present invention, the belt conveyor include bracket, bracket both ends on be arranged roll shaft,
The feed belt that is sheathed on roll shaft has been installed on motor on specific roll shaft for drive roller shaft rotation.
The surface of preferred embodiment in accordance with the present invention, the feed belt is equipped with V-arrangement raised line, is conveyed with increasing mud
Frictional force in journey.
Funnel, grab bucket is arranged in one end of the feed belt of the belt conveyor in preferred embodiment in accordance with the present invention
Machine is grabbed the mud come and is firstly placed in funnel, then the mud in funnel is placed on to one end of the feed belt of the belt conveyor
On, mud is delivered to by the other end of feed belt by the operation of feed belt, needs to backfill mud in embankment until being put into
Region in.
Preferred embodiment in accordance with the present invention, the grab claw and belt conveyor are individually positioned on two blockships, this
It is connected between two blockships by pull rod.
Preferred embodiment in accordance with the present invention, Grab grab the sea area of mud apart from 0.05-500 kilometers of embankment periphery.
Compared with prior art, the method in reclaiming land around sea domain of the invention, which has the following beneficial effects:, of the invention encloses sea
The method in epeirogenetic domain is grabbed by the mud that grab claw ships dredger to belt conveyor, and the concentration of the mud of backfill increases
High, water content reduces, and the construction cost in reclaiming land around sea domain is low, the duration is fast, environmentally protective, has prevented current strand and has inhaled ship sewage discharge
Pollute the status of environment.
Detailed description of the invention
Fig. 1 is the top view of grab claw of the present invention and belt conveyor.
Fig. 2 is the front view of grab claw of the present invention and belt conveyor.
Specific embodiment
Below in conjunction with specific embodiment, the present invention will be further described.It should be understood that following embodiment is merely to illustrate this
The range of invention and is not intended to limit the present invention.
Embodiment 1, certain reclaiming land around sea domain engineering
In conjunction with Fig. 1, Fig. 2, the construction method of the reclaiming land around sea domain engineering of the present embodiment includes the following steps:
Step (1) is arranged embankment in the peripheral section that need to enclose sea region, has the cooperation of blockship 1 in embankment, install on blockship 1
There are grab claw 2 and belt conveyor 3；
Step (2) grabs mud in the sea area that distance encloses sea region embankment periphery suitable distance using dredger, and shipping is extremely
Sea region is enclosed, close to 1 side of blockship；
Step (3) is grabbed using the mud that the grab claw 2 on blockship 1 ships dredger to belt conveyor 3, is passed through
The belt 33 of belt conveyor 3 is delivered to the region progress land-based area backfill for needing to backfill mud in embankment, while moving blockship 1
Mud backfill is carried out, until forming land-based area.
Preferably, the belt conveyor 3 include bracket 31, bracket 31 both ends on be arranged roll shaft 32, be sheathed on roller
Feed belt 33 on axis 32 has been installed on the motor rotated on specific roll shaft 32 for drive roller shaft 32 and (has not shown in figure
Out).It is highly preferred that the surface of the feed belt 33 is equipped with V-arrangement raised line 331, to increase the frictional force in mud transmission process.
In one end of the feed belt 33 of the belt conveyor 3, funnel 4 is set, grab claw 2 is grabbed the mud come and is firstly placed in funnel 4,
Then the mud in funnel 4 is placed on one end of feed belt 33 of the belt conveyor 3, passes through the fortune of feed belt 33
It is about to mud and is delivered to the other end of feed belt 33, until being put into the region for needing to backfill mud in embankment.It is highly preferred that
Grab claw 2 and belt conveyor 3 are individually positioned on two blockships 1, are connected between the two blockships 1 by pull rod 5.
