Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
It should be noted that a kind of method of raising hydraulic reclamation flatness of the invention, be based on floating type Temporary Cofferdam into
It is capable, wherein floating type Temporary Cofferdam, including floating type breakwater, interior side closure dam and anti-reflux weir, floating type breakwater and anti-
Reflux weir is vertically arranged to form L-shaped fence, and interior side closure dam is installed on the outside of anti-reflux weir and is arranged in parallel with floating type breakwater,
And hydraulic reclamation pipe is installed on anti-reflux weir, hydraulic reclamation pipe passes through anti-reflux weir and extends to floating type breakwater side, and floating type anti-
Wave dike is spliced by rubber self floating pipe
In use, the region of hydraulic reclamation as needed first, floating type Temporary Cofferdam is installed on hydraulic reclamation boundary direction simultaneously
It is fixed, then according to the technical solution of the present invention, hydraulic reclamation is carried out to hydraulic reclamation area.
For the technical solution that present invention be described in more detail, blown refering to Figure 1, the present invention provides a kind of improve
The method for filling out flatness, comprising the following steps:
S1, hydraulic reclamation pipe is being laid to hydraulic reclamation region, and is installing sinker in hydraulic reclamation pipe end, to reduce hydraulic reclamation object at tube head
The flow velocity of material prevents from washing away, so that hydraulic reclamation material is evenly scattered in hydraulic reclamation area；
S2, under hydraulic reclamation pipe not swing state, obtain hydraulic reclamation pipe tube head by measuring and hydraulic reclamation pipe tube head can cover model
Enclosing the distance of line between boundary point, hydraulic reclamation pipe tube head and hydraulic reclamation pipe tube head can line and hydraulic reclamation between coverage area boundary point
Vertical range between angle between pipe tube head axis and hydraulic reclamation pipe tube head axis and Temporary Cofferdam calculates and obtains hydraulic reclamation pipe
Swing angle；
The swing angle of S3, the hydraulic reclamation pipe acquired according to calculating, the swing angle for adjusting hydraulic reclamation pipe carry out hydraulic reclamation area
Filling.
The present invention controls the flow velocity of hydraulic reclamation material using sinker due to having installed sinker in hydraulic reclamation pipe tube head, and
It is calculated by detection, to obtain the swing angle of hydraulic reclamation pipe, according to the swing angle of hydraulic reclamation pipe, to fill hydraulic reclamation area, thus with
The too low problem of the height of hydraulic reclamation caused by hydraulic reclamation excessive height or swing angle caused by preventing swing angle too small are excessive, with
Guarantee its hydraulic reclamation flatness, improves its construction efficiency.Wherein, the structure of sinker please refers to shown in Fig. 3.
In another preferred embodiment of the invention, step S1 of the invention further include: at the sinker end of hydraulic reclamation pipe
End installs rubber swing pipe additional, and the swing angle of hydraulic reclamation pipe is further increased by rubber swing pipe, is blown to can not only expand it
Area is filled out, its construction efficiency is improved, and due to the characteristic of rubber swing pipe, the flatness in hydraulic reclamation area can be effectively improved.It is preferred that
, the swing angle of the rubber swing pipe of the utility model is 0 ° to 90 °.
Please continue to refer to shown in Fig. 2, the formula of mathematical of step S2 of the invention are as follows:
α=arcsin (Lb/La)-β；
Wherein, LaIndicate the hydraulic reclamation pipe tube head and the hydraulic reclamation pipe tube head can between coverage area boundary point line away from
Indicate that the hydraulic reclamation pipe tube head and the hydraulic reclamation pipe tube head can line and the hydraulic reclamation pipe pipes between coverage area boundary point from, β
Angle, L between head axisbIt indicates the vertical range between the hydraulic reclamation pipe tube head axis and Temporary Cofferdam, is blown described in α expression
Fill out the swing angle of pipe.
It is worth noting that hydraulic reclamation pipe of the invention is rubber self floating pipe, and the laying of hydraulic reclamation pipe is divided into water borne conduit cloth
If being laid with continental line.
Wherein, waterborne pavement pipeline should determine reasonable pipeline connection type according to the natural conditions of job location, prevent
Occurs the construction accident of disconnected pipe when stormy waves is big.The hydraulic reclamation pipe of fixed pipeline section waterborne mostly uses self floating pipe or steel pipe and scratches
Property pipe be indirectly connected, lengths of steel pipes is and fixed with pipeline anchoring by binary platform bearer.Immersed tube can be used in special circumstances.It is waterborne floating
Pipe is usually first assembled into segmentation, and section length is advisable with 150-160m.It should will construct while assembling float tube waterborne segmentation
Anchor arrangement is appropriate.Then every section of float tube traction waterborne is in place to construction area, usually since immersed tube head or land and water frame head successively
Docking.
It is generally carried out using flood slack in sea area or tidal reach float tube.Its method is as follows: the float tube being first clamped
Sludge discharging area is clamped or is fixed on land spoil disposal tube head；Then the other end of float tube and dredger stern sludge pipe are clamped；
Tugboat or anchor ship top float tube downstream are finally used, will be risen in time, the pipe anchor in ebb tide direction is cast.
And land hydraulic reclamation line layout includes two part of land hydraulic reclamation pipe and land and water pipe support, land and water pipeline is connected with two kinds of sides
Method: coupling one is direct with hydraulic reclamation pipe hose waterborne, and one is centres to set up pipe support or platform connection.
During hydraulic reclamation pipe is laid, land hydraulic reclamation pipe should be laid as far as possible, and reduces laying hydraulic reclamation pipe waterborne, to subtract
Few sludge pipe hydraulic loss waterborne.
The method of a kind of raising hydraulic reclamation flatness of the invention, by adding sinker on hydraulic reclamation pipe, to improve hydraulic reclamation
The diffusion area of pipe reduces nozzle impulse force, to accurately control hydraulic reclamation area absolute altitude to play, improves the purpose of hydraulic reclamation flatness.
As it is a further advantage of the present invention that the present invention can also be according to hydraulic reclamation pipe tube head and to line between hydraulic reclamation region
Distance etc., with swing angle needed for accurately obtaining the different hydraulic reclamation pipes to hydraulic reclamation region, with further accurate control hydraulic reclamation area
Flatness and its absolute altitude.
Finally, the present processes are only preferable embodiment, it is not intended to limit the scope of the present invention.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the invention
Within the scope of.
