Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] Step 1: Before the wall plate is assembled, firstly divide the tank bottom plate according to the circumference, and then set a 600mm high Φ325*12 steel pipe support or I50a on the bottom plate along the intersection of the wall plate circumference line and the bottom plate angle bisector line. The top is complemented by a 400mm*400mm*16mm steel plate as an assembly platform 3. And level it with a level gauge, the level error of the support is ≤ 2mm, return the inner circle of the wall plate 2 on the bottom plate 1 vertically to the plane of the support steel plate, set limit baffles on the inner side and the outer side, as a tire for the paired wall plate After the mold support is set up, the geometric dimensions should be rechecked to ensure the diameter of the wall panel. (Assembly platform see attached figure 1 )
[0034] Step 2: Accurately install the ...

The invention discloses a drum type steel storage tank hydraulic lifting and inverting method based on a BIM technology. A holding-latch jack is adopted as a main body, a lifting device supporting system is subjected to integrality safety design through the BIM technology, an engineering virtual model is established, the construction process is simulated, and the whole construction project is optimally controlled; and hydraulic pump stations of different types and hydraulic pipeline system accessories of different types are arranged, single control over a hydraulic lifting device is changed into integral control, continuous jacking is changed into stepped lifting, simple, safe and reliable splicing platforms are used for assistance, and drum type steel storage tank reverse mounting construction complete equipment is formed. According to the method, single control over the single hydraulic lifting device is changed into integral control over multiple hydraulic lifting devices, so that the situations that lifting heights are inconsistent due to time difference in the lifting process and load deviation occurs to a whole storage tank are changed to a great extent, and the overturning phenomenon is effectively prevented and controlled. The technology is simple, easy to apply in fields, suitable for construction of various drum type steel storage tanks, and more suitable for projects with the high quality requirement, narrow and small sites, short construction periods, low estimated cost and harsh constriction environment.
Description
technical field [0001] The invention relates to a method for installing a steel storage tank, in particular to a method for installing a large-diameter, large-scale cylindrical steel storage tank. Background technique [0002] With the rapid development of the country's industrialization level and the needs of large-scale operations in various industries, the requirements for the storage capacity of various steel storage tanks are getting higher and higher, and the trend of steel storage tanks towards large-scale development is more obvious. Traditional steel storage tanks The tank is constructed by the center column method, the air blowing method, the mechanical chain lifting method, and the mast electric chain lifting method. As the storage tank tends to be bigger and higher, the traditional construction process is not only costly, but also limited by the site, construction efficiency, safety, etc. In the traditional installation method, the hydraulic lift may have inconsi...
