According to the design requirements of steel arch in machining field using I-beam bending machine processing, integrated transport to the excavation face, on-site assembly. The quality of steel arch made by "sampling" inspection, accurate in processing system like 1:1, each piece of steel arch forming after the trial spell and performed better than the sample examination, allowable deviation of 30mm.
The bending machine in the production of steel arch advantage:
Processing steps on the I-beam arch from you know, before the main production equipment is not steel arch bending machine bending machine but, and now the bending machine is widely used and this is why?
Compared with the traditional arch bending machine machine, in the production of steel arch advantage is mainly reflected in the following aspects:1 simplifies the process. A 12M long I-steel can be formed at one time, only to be cut once in the final welding, and the cost of coke is saved and the cost of processing is greatly reduced.
2 save more human resources, each ton of I-steel from raw material to bending forming, only four people and one group, and the production time is only about twenty minutes.
3 is the bending quality is greatly improved, not only effectively eliminates the distortion phenomenon, and the bending of arch radian uniform.
In the process of tunnel construction, the tunnel dug out after the general channel needs reinforcement, with bending machine will I-beam bent into the beginning, and then bend well I-beam is fitted to the corresponding position to play a supporting role to complete the main cave, supporting engineering, steel mesh shop in the cave on the wall, this is mainly for the subsequent shotcreting ready. After completion of support and preparation, shotcreting can be carried out, and the cement slurry is sprayed onto the walls of the tunnel through the shotcreting machine, so that the main body's construction is completed. The steel beam bending machine and the jet grouting machine are indispensable tools in the construction of the tunnel.
