The specific embodiment
For accompanying drawing, embodiment of the present utility model is described further below:
As shown in the figure, a kind of thin-wall steel tube shaft tower, comprise the body of rod 1, the bar section 2 that the described body of rod 1 is sealed by multistage is spliced, described in each, in bar section 2, be equipped with enclosed inner chamber 3, and surface of bar section 2 is equipped with the aerating device 4 communicating with its inner chamber 3 described in each, by described aerating device 4, can toward inner chamber 3, inject the gas of certain pressure, aerating device 4 adopts one way valve.According to such scheme, the steel pipe pole section that this thin-wall steel tube shaft tower is sealed by multistage inner chamber is spliced, every section of bar section surface is provided with one can be toward the gas inflated device that has injected certain pressure in the steel pipe of sealing, increase the ability of counter-bending, the anti-twist distortion of steel pipe tower integral body, improved greatly the rigidity intensity of shaft tower; Compared with prior art, meeting the next wall thickness that can reduce steel pipe of equality strength condition to reduce the weight of shaft tower, also can reach the object that reduces cost of manufacture.There is lightweight, convenient transportation, easy construction, safe devoid of risk, antiseptic property is good and low cost and other advantages.In addition, because shaft tower inner chamber adopts airing form, without air, enter, therefore, shaft tower inside has effectively, reliable antiseptic property.
In the present embodiment, the inner chamber supercharging 2-10MPa of each section of bar section.When the gas pressure injecting in every section of bar section is 2-10MPa, prevent from not reaching corresponding requirement of strength or because the excessive performance of bar section that causes of pressure of injecting is affected due to too low, therefore adopt 2-10MPa the most suitable, it can reach the rigidity intensity that has improved bar section, has again lightweight, convenient transportation, easy construction, safe devoid of risk and low cost and other advantages.
In the present embodiment, bar section is 3 sections, and the described body of rod 1 is spliced successively by bar section epimere 11, bar section stage casing 12 and bar section hypomere 13.The preferred 7M-15M of the described body of rod, for example, when body of rod length is 10M, its middle rod section epimere 11 is 3.6M, and weight is 28.8KG, and bar section stage casing 12 is 3.5M, and weight is 37.2KG, and bar section hypomere 13 is 2.9M, and weight is 36.1KG.When described body of rod length is 15M, its middle rod section epimere 11 is 6M, and weight is 67.5KG, and bar section stage casing 12 is 5.3M, and weight is 49KG, and bar section hypomere 13 is 3.7M, and weight is 66KG.Adopt above-mentioned processing criterion, after inflation in bar section, there is convenient transportation, cost is low and combination property is stable, can certainly adopt 7M, 8M, 9M, 11M, 12M, 13M, 14M equal-specification.
In the present embodiment, between each section of described bar section 2, by flange, be fixedly connected with.Between each section of bar section 2, adopt flange to be fixed connection, dismounting is simple, convenient, and installation fastness is high, and stability is strong, to use, brings convenience.
In the present embodiment, described in each, bar section 2 outsides are welded with cat ladder.By welding cat ladders 6 in each section of bar section 2 outsides, after splicing by flange each other, constructor can climb by cat ladder, and firm welding is high, and stability is strong.
A kind of thin-wall steel tube shaft tower processing method, first with iron plate, be processed into the bar section of circle or polygonal shape, every section of bar section is the steel pipe of inner chamber sealing, in every section of bar section, fill aerating device, then utilize aerating device toward the inner chamber of every section of bar section, to inject the gas of certain pressure, make it reach the pressure of standard.Adopt above-mentioned processing mode, easy to process, and the bar section of shaft tower after processing has lightweight, convenient transportation, easy construction, safe devoid of risk and low cost and other advantages.
A kind of construction method of thin-wall steel tube shaft tower, processing and the shaft tower hypomere of the gas of substituting the bad for the good, shaft tower stage casing and shaft tower epimere transport job site to, first use artificial to the shaft tower hole group vertical rod tower hypomere having dug, make shaft tower hypomere there is certain terrain clearance, then detect the center of shaft tower, circuit-line direction and verticality, then single mast formula pole is fixed on shaft tower, this pole is fixed on upper and lower two positions, place of shaft tower hypomere shaft tower root, by single rope, be fixed on the top of pole, again in shaft tower, epimere splices fixing by flange, shaft tower stage casing and shaft tower hypomere are connected through the hinge, then with pole, adopt inverted single-point lifting barre midsection be fixed on shaft tower hypomere and form Lifting Method in Pole Tower Integral Hoisting by flange, then dismantle pole, install.Adopt above-mentioned construction method group to found 7M-15M differing heights (supercharging) thin-wall circular steel pipe, can prevent the generation of the human casualty accident of falling shaft tower, have advantages of that security reliability is higher, this construction method is fairly simple, without plant equipment and heavy Work tool.The bending resistance of the complete instead of steel reinforced concrete pole of this product, resistance to compression, anti-ly turn round, anti-elegant ability, application life is short, easily produces the shortcomings such as vertical, horizontal crack.Adopt single mast formula fixedly pole found, remove shaft tower under equal conditions, construction period shortens greatly, saves labour.Found, remove shaft tower and partly save artificial approximately 70% left and right, ascend operation is without climbers, and shaft tower eminence installation exercise omits, and working grounding line adopts portable, and earthing pole can omit.Labour intensity greatly reduces, also alleviated communications and transportation pressure, energy conservation again, this shaft tower is specially adapted to rescue and relief work, landform more complicated: the more difficult location of walking, the landform that is unfavorable for mechanized construction, has fully demonstrated material light, convenient transportation, Work tool is few, construction safety is convenient and swift, uses manually less, and the features such as fast are shifted in construction plant.The continuous productive process that is conducive to construction, the progress of quickening construction, shortens the cycle of constructing, and reduces the cost of constructing, and has obvious safety and economic benefit.
Be to adopt spirit level to detect center, circuit-line direction and the verticality of shaft tower, the terrain clearance of shaft tower hypomere is not more than 1.2 meters.By adopting spirit level to detect, circuit can off normal, and accuracy is high, easy to use, and result of use is good.
Employing wire rope tackles lifts by crane in shaft tower, epimere, and lifting angle is greater than 30 °.By adopting wire rope Lever Blocks lifting shaft tower, crane gear is lightweight, is convenient to transportation, installs and operation, and suspension clamp angle is greater than 30 °, the security reliability while improving lifting.In addition, shaft tower span is greater than 60 meters, effectively reduces shaft tower use amount and reduces construction costs.
In the present embodiment, the described body of rod 1 is the frustum cone structure that external diameter increases successively from top to bottom.The body of rod 1 is external diameter by the steel pipe of each section and increases successively in the frustum cone structure of 1/75 elongated ratio and be spliced, and during installation, the stability of shaft tower, in the high ratio buried depth of 1/6 bar, after installation, is difficult for tilting, topples.
Embodiment should not be considered as the restriction to invention, but any improvement of doing based on spirit of the present invention, all should be within protection scope of the present invention.
