Abstract
Provided is an installing method of a marine anemometer tower base structure. The marine anemometer tower base structure is a vertical marine anemometer tower base, a basic mode that three steel tube piles and a guiding frame are combined, the inclination of a guiding sleeve is the same to that of a anemometer tower pile foundation, the requirement for the pile foundation location degree is met, and columns of a pile driving frame are in welding connection with oblique support rods through horizontal connecting rods to form a steel truss structure. The three steel tube piles are sequentially driven through the guiding sleeve, datum planes of the piles are cut, the pile driving frame is recovered after piling operation is finished, a small basic platform is added and then the guiding frame is welded and installed onto the three steel tube piles in an aligning mode. By means of the method, the stress of steel tube pile foundations is definite, extreme condition resisting capacity is strong, and influence of seabed ocean currents on the steel tube pile foundations is small. In addition, the installing construction is convenient, a construction period is short, the construction cost is low, and the base structure is safe, reliable and long in service life.
Description
Technical field
What the present invention relates to is a kind of mounting method of marine anemometer tower foundation structure, and the mounting method especially for the marine anemometer tower foundation structure of leading truck is applicable to Oversea wind power generation.
Background technology
The wind-powered electricity generation resource is reproducible non-polluting energy sources, and China coastline is very long, compares the land wind-power electricity generation, the prospect of ocean wind-power electricity generation is more wide, wind energy on the sea aboundresources and stable, wind regime is better than land, and is subjected to soil utilization, noise pollution, Electromagnetic Interference less.Changing Pattern and the feature of the primary clear and definite greater coasting area wind of exploitation wind energy on the sea, offshore land wind speed that the weather station is surveyed is owing to be subjected to factor affecting such as surface roughness and atmospheric stability, with marine wind speed certain difference is arranged, can not directly be used for representing marine wind regime, the direct method of obtaining the sea turn resource data is to set up anemometer tower at sea.
The marine anemometer tower that present China has built up is fewer, marine anemometer tower is except bearing dead load, equipment self-weight, wind load, geological process, temperature load, icing load, installing the maintenance load, because its residing marine environment, also will bear wave load, morning and evening tides load, ocean current load and ship collision load, design conditions are more complicated than conventional land building.
Based on the complexity of marine anemometer tower load, China lacks in experience aspect the anemometer tower construction installation simultaneously, and cost and the duration of anemometer tower installation at present all are in higher level.
Summary of the invention
Main purpose of the present invention provides a kind of mounting method of marine anemometer tower foundation structure, and this mounting method easy construction, safe and reliable can improve efficiency of construction and quality effectively, reduces the construction cost cost simultaneously effectively.
The technical scheme that technical solution problem of the present invention adopts is, a kind of mounting method of marine anemometer tower foundation structure, anemometer tower foundation structure is marine self-supporting anemometer tower basis, adopt 3 base forms that steel pipe pile is combined with leading truck, the anemometer tower pile driving frame is formed by the leading truck structure of modification, namely increase up and down two-layer loudspeaker guiding in the column outside of correspondence by welding and form fairlead, the fairlead gradient is identical with anemometer tower pile foundation gradient, and meet the degree requirement of pile foundation position, each column of pile driving frame is welded to connect by horizontal brace rod and inclined support bar, forms the steel truss structure form.By respectively 3 steel pipe piles being squeezed into successively by fairlead, a cutting stake datum after piling work is finished, reclaims pile driving frame, adds behind the basic chain-wales leading truck by on contraposition welded and installed to 3 steel pipe pile.
The invention has the beneficial effects as follows steel pipe pile basic stress things to know, opposing extreme operating condition ability is stronger, and the seabed ocean current is less to the influence of steel pipe pile basis, this installation simultaneously is convenient, and construction period is shorter, and cost is lower, foundation structure is safe and reliable, and application life is longer.
