Description
Technical field
The utility model relates to line transportation waterborne, belongs to buoyancy aid manufacturing technology waterborne.
Background technique
In all many-sides such as oil, chemical industry, mining, environmental protection and buildings, all relate to conveyance conduit laying method waterborne and buoyant means waterborne.In ocean engineering rivers and lakes engineering, often require on the water surface, to lay conveyance conduit and buoyancy aid manufacturing waterborne.Usual way is: adopt airtight metal cabinet to make buoyancy aid, bubble through the water column, pipeline is fixed on it, link end to end between the pipeline then and lay.It is big to exist the buoyancy aid own wt, and water surface task difficulty is big, and laying project intensity is big, engineering inefficiency, problems such as operating life weak point.In addition, because the bump of external force, the corrosion of seawater, the buoyancy aid water inlet of leaking gas easily causes the buoyancy aid sinking.The damage because of buoyancy aid often causes pipeline break, affects the proper functioning of pipeline.
Summary of the invention
The utility model is at order the problems referred to above, design a kind of in light weight, buoyancy is big, the life-span is long, lay novel easily buoyancy aid waterborne.
The technical solution of the utility model is: adopt peripheral hardware thin-wall high intensity material protection layer and be full of the buoyancy aid of lightweight material in it; With climbing or marine glue buoyancy aid is fixed on the conveyance conduit.
Described buoyancy aid is divided into circular float and square float, comprises plunger core, protective layer, climbing, marine glue etc.Circular float is generally two half-cylindrical integrators, and pipe hole is left in the centre, and plunger core adopts rigid foam to make, being in proportion of the size of float and pipeline.Shown in Figure 2 as Fig. 1
The length of circular float is got the 1/2-1/8 of duct length, and float generally is divided into several, installs in the pipeline equal intervals, and two floats are installed on the every conveyance conduit at least.When the length of float get duct length 1/1 the time, be called full-covered type, be used for needing the pipeline of heat-preserving anti-freezing.
The diameter of circular float is got 3-6 times of pipe diameter, gets big value when the span of conveying material, pipeline material proportion and float is big; Otherwise, get the small value.
Square float such as Fig. 3 are shown in Figure 4:
The width of square float is got 3-8 times of tubing width, and big value is got in the waters that stormy waves and flow velocity are big; Otherwise, get the small value.
As the certain altitude that need surface the float pipeline, the value of nargin coefficient that can suitably increase the height of float is adjusted.
Described lightweight material can adopt rigid foam, as urethane foam, GPPS foamed plastics etc.
Described peripheral hardware protective layer adopts high-strength thin-walled material to be wrapped in the surface of float.High-strength material can adopt nylon, plastics, galvanized sheet iron, glass fibre reinforced plastics etc.Protective layer is taked antiultraviolet, and is anti-aging, strengthens measures such as toughness, to satisfy usage requirement.Generally be that protective layer and plunger core, climbing manufacture and design the installation of building site, back in advance in factory.Also can adopt banded protective layer, twine on the gluing plunger core of finishing.
Described conveyance conduit laying method waterborne is fixed on float on the pipeline earlier, fastens the rope that links with working boat, send down and lays the waters, more natant pipeline is connected mutually.
It is little that the present invention has buoyancy aid deadweight, lays convenient disassembly, high working efficiency, long service life, characteristics such as maintenance cost is low.Can in the environment of 6 grades of Pu Shi wind scales, unrestrained high 2m, flow velocity 2m/s, carry out operation.Compare with traditional method and technology, work efficiency improves 1 ~ 3 times, and the duration shortens more than 40%, and cost reduces about 35%, and reliability and Security all are greatly improved.
