Description
Technical field
The present invention relates to a kind of laying works of geotextiles below geotextile laying technical field more particularly to long piled wharf
Skill.
Background technique
At present below long piled wharf geotextile laying multiselect dredge repair slope when laying, then carry out pile sinking again and jackstone applied
Work, but there is following defects for this paving mode: (1) work surface needed for floating piling operation ship is big, pile sinking operation by
Geotextile laying speed restrict, need geotextiles along bank slope be laid with complete it is 150-200 meters wide after can carry out pile sinking operation；(2) native
Work cloth is accomplished to jackstone ballast time interval length (can carry out after needing pile sinking) from laying, and geotextiles are rushed by subsea current
It dissipates, the geotextiles more than water surface are easy aging for a long time by the sun according to shining on the bank；(3) when pile sinking, pile top penetrates geotextiles rear
It can sink under mud face, geotextiles should be easy to happen in the process and slide, tear；(4) when pile sinking, when stake position is located just at compress
When on packed rubble or other compress building stones, it is easy to happen stake position deviation；So being badly in need of studying the new laying geotextiles of one kind
Technique solves the above problems.
Summary of the invention
The present invention exactly against the above technical problems, provides a kind of laying process of long piled wharf lower section geotextiles.
The present invention to achieve the above object, using following technical scheme: the laying work of geotextiles below a kind of long piled wharf
Skill, which comprises the following steps:
(1) cut out: geotextiles are divided into the production of two kinds of forms, the geotechnological yardage roll between a kind of framed bent for odd number；One kind is adjacent
Overlap joint yardage roll between two width geotechnique's yardage rolls；
(2) early-stage preparations: geotechnological yardage roll is unfolded on the ground, according to drawing size in corresponding even number stake position G row and B
A circular hole is cut at two piling bars at row, then using the nylon rope of two 20m long by two of geotechnological yardage roll one end
Angle toggles, and the other end of two nylon ropes ties up on batching roller bearing, is rotated further by batching roller bearing, by the neat volume of geotechnological yardage roll at this
On batching roller bearing；
(3) it positions: batching roller bearing is placed on positioning floating drum, positioning floating drum is dragged to wharf apron in position, positioning is floating
Position side is stayed after cylinder in parallel to refute, refutes in position side and is fixed using four anchor hawsers, and four anchor hawsers are arranged in eight words；
(4) it is laid with geotechnological yardage roll:
After the completion of A1 positioning, first then the other end bolt jail of geotechnological yardage roll is spread by cloth people using the nylon rope of a 50m long
Member's seating towboat send the nylon rope of root 50m long on the bank, and then the other end of geotechnological yardage roll is dragged to by waterfall personnel on the bank
Bank side, then the circular hole of cutting is set on two piling bars at corresponding even number stake position G row and B row, so that geotechnological yardage roll is open and flat
On the water surface；
After the completion of A2 spread, enclosed using nylon rope around piling bar one in the contact position of geotechnological yardage roll and piling bar, the two of nylon rope
End and the label position bolt jail on geotechnological yardage roll；
After A3 fastens geotechnological yardage roll, the sandbag of 24-26kg is tied up on geotechnological yardage roll at piling bar first, it then will be husky
Bag is placed on driving cap, after the sandbag at all piling bars is all fastened, is pushed into water from the land side Ce Xianghai by sandbag, so that native
Work yardage roll sinks, until seabed；
After the completion of geotechnological yardage roll at A4 piling bar is laid with, to the mobile station keeping ship in extra large side, paving cloth personnel, which rotate batching roller bearing, to be made
It obtains geotechnological yardage roll to fall off from batching roller bearing, station keeping ship is every two meters mobile to extra large side, and paving cloth personnel are just one on geotechnological yardage roll
Then geotechnological yardage roll is sunk to seabed by sand discharge bag；After all geotechnological yardage rolls sink to marine, continue to move backward station keeping ship, one
Side running fix ship, nylon rope of one side loose winding on batching roller bearing, until geotextiles sink to seabed completely, then by nylon rope solution
It opens, extracts out；During spreading cloth, diver observes the laying condition of geotextiles under water, to the place for having contraction flattening in time, uses
Sandbag presses；
(5) it is laid with overlap joint yardage roll:
B1 is laid with the overlap joint yardage roll at piling bar: the overlap joint yardage roll cut out is placed between the geotechnological yardage roll of adjacent two,
Then overlap joint yardage roll is pressed with sandbag；
B2 is laid with the overlap joint yardage roll at the 30m of wharf apron: the paving mode for overlapping yardage roll and the geotechnique at the 30m of wharf apron
The paving mode of yardage roll is identical.
The uniformly distributed roller bearing is the seamless steel pipe that a diameter is 10cm, and bearing, bearing are welded in the both ends of seamless steel pipe
It is welded on the bracket welded with fashioned iron, bracket is welded on positioning floating drum, and the both ends of batching ball, which are welded, prevents geotextiles
The limit plate to fall off from batching ball is rolled up, and the distance between limit plate is 6m.
In the A2 of the step (4), there are the gaps of 20-30cm between nylon rope and piling bar.
Geotechnological yardage roll every breadth 6m, long 77m in the step (1)；Overlap the every breadth 2.3m of yardage roll, long 77m.
It preferably, further include after geotechnological yardage roll is all completed with overlap joint yardage roll, paving cloth personnel take towboat and are being laid with
Geotechnological yardage roll and overlap joint yardage roll on random throwing sandbag, realize the compacting to geotechnological yardage roll and overlap joint yardage roll.
The beneficial effects of the present invention are: the present invention adjusts the sequencing of pile sinking and geotextile laying, heavy
After the completion of stake, then the laying of geotextiles under harbour is carried out, efficiently solves drawbacks described above；And in geotechnological yardage roll in this technique
Upper sandbag is pressed while laying with overlap joint yardage roll, so that geotextile laying is more smooth, not easily shifted, laying effect is preferable.
