If the usual production and installation method is used, that is, to make tiles first and then assemble the tiles into a hollow cylinder for overall hoisting or single tile hoisting, this method requires multiple stiffening rings with angle steel when making tiles. This not only increases the production cost, but at the same time, whether it is a single tile or assembled as a whole, a larger crane is required at a higher level. At the same time, there is a construction safety risk for personnel working at height, which is high in cost and low in efficiency.

Embodiment 1
[0029] like Figure 1~6 Among them, a manufacturing method of a large cylindrical storage tank comprises the following steps:
[0030] 1. On the tank body installation platform 5 in the tank body 1, a plurality of lifting columns 3 are evenly distributed along the circumference, and an electric hoist 4 is arranged on the lifting column 3, and the height of the lifting column 3 is higher than a layer of tank body components;
[0031] 2. The first layer of tank body components is assembled by welding and assembling multiple arc-shaped segments.
[0032] In a preferred solution, a stiffening ring 7 is welded at the middle of the inner wall or outer wall of each layer of the tank member.
[0033] A hoisting stiffening ring 2 is installed inside the tank member of the first layer near the bottom, and lifting lugs 23 are provided on the hoisting stiffening ring 2 corresponding to the lifting column 3;
[0034] In a preferred solution, an annular assembling platform 6 is also provi...
Embodiment 2
[0047] On the basis of embodiment 1, illustrate further with example:
[0048] 1. Prepare the tank body installation platform 5 of the storage tank first, and pre-embed and install the lifting column 3 and the ring-shaped assembly platform 6 embedded parts for assembly at the corresponding positions of the tank body installation platform 5;
[0049] 2. According to the height of the hollow cylinder of each layer, that is, the tank member, usually the width of the commercially available steel plate shall prevail. Generally, the width of the plate is 1.5 meters or 2 meters. The total weight of the entire storage tank is designed to determine the height of the lifting column. and quantity, take a sand and gravel tank as an example to describe the production and installation method in detail:
[0050] A sand and gravel tank has a diameter of 16m and a height of 18m. The material of the tank body is 8mm steel plate supplemented with a small amount of angle steel to make a stiffenin...

Abstract
A method for manufacturing a large cylindrical material storing tank comprises the following steps that a plurality of hoisting stand columns are evenly distributed inside a tank body in the circumferential direction, wherein the hoisting stand columns are provided with electric hoists; a first layer tank body member is formed by splicing a plurality of arc-shaped pipe pieces, the part, close to the bottom, inside the first layer tank body member is provided with a hoisting stiffening ring, and a lifting lug is arranged on the hoisting stiffening ring; the first layer tank body member is hoisted by the electric hoists; a second layer tank body member is formed by splicing a plurality of arc-shaped pipe pieces below the first layer tank body member, the electric hoists are operated to enable the first layer tank body member to fall at the upper end of the second layer tank body member, and the first layer tank body member and the second layer tank body member are connected in a welding mode; by parity of reasoning, a plurality of layers of tank body members are welded into the whole tank body; the large cylindrical material storing tank is installed and manufactured through the steps. According to the method, the effect of the transporting and storing steps on the tank body members is reduced, the using cost of hoisting devices is reduced, the manufacturing and installing efficiency and tank body quality are improved, and manufacturing and installing cost is reduced.
Description
technical field [0001] The invention relates to the field of making tank bodies, in particular to a method for making a large cylindrical material storage tank that can be used in the fields of hydropower, building construction or chemical industry. Background technique [0002] Large circular storage tanks are often used in the construction of hydropower stations and other industries. The characteristics of this type of circular storage tank are large volume, so its diameter and height are relatively large. For example, a large cylindrical storage tank used in a certain project With a diameter of 16 meters, it is welded by 12 layers of tank members with a height of 1.5 meters each. After calculation, the weight of a single layer is 5154 kg, and the total weight is 61848 kg. The tank body material for making this kind of storage tank--steel plate is mainly 6mm-10mm thin steel plate, so its weight is relatively light and its strength is low. If the usual production and insta...
