Description

Background
The blast furnace ore coke tank hopper group comprises a plurality of blast furnace ore coke tank hoppers, and the blast furnace ore coke tank hoppers are oversized eccentric concrete hoppers and have the characteristics of large volume, eccentric load, high construction difficulty, high risk and the like. The four inclined plane angles of each blast furnace ore coke tank hopper are different and relatively independent, and larger horizontal thrust exists in the concrete pouring process of the blast furnace ore coke tank hopper, so that the strength, the rigidity and the overall stability of the supporting system are very tested. The blast furnace ore coke tank hopper depends on ring beams and vertical walls to hang, a firm supporting frame needs to be erected to support the template in the construction process, and the template is poured in sections from bottom to top.
The journal literature Nie Li, xiong Chang, construction technology and 43 rd month 12 in 2014 explain the structural form, load characteristics and corresponding construction method of the blast furnace ore coke tank hopper. Under the general condition, the support frame for blast furnace ore coke tank funnel construction is a fastener type support frame, and the disc buckle type support frame is adopted in fresh, and the reason is mainly that the following points are adopted: first, blast furnace ore coke tank funnel belongs to decentered and structural style top-down is the variant step by step, and adopts the support frame of equal modulus in order to satisfy the different support elevation loss of funnel side great, and economic turnover is unfavorable. In the pouring process of the second and blast furnace ore coke tank funnels, along with the continuous increase of concentrated load and the influence of eccentric horizontal thrust, the support frame is required to be encrypted at the resisting side, and the equal-modulus support frame is not easy to implement due to the connection characteristic of the equal-modulus support frame. And thirdly, the flexible connection form of the fastener type supporting frame is flexible in meeting different supporting elevation and resisting encryption, and is suitable for being used as a supporting system in construction of an eccentric and different structure of a coke chute funnel.
However, the disadvantage of the clip type support frame for the blast furnace mine trough hopper support system is also highlighted: firstly, due to long turnover and natural corrosion, a rack pipe with the pipe wall thickness reaching the standard is difficult to find in the market at present; secondly, the reliability of the support frame system is greatly influenced by the strength and rigidity of the steel pipe and the fastener; once the encryption area of the supporting system is built, connection inspection and fastening bolt re-tightening cannot be performed by people with narrow space.
