Analyze the cause of torsion in coal bunker slipform construction

existCoal bunker slipformThe control of verticality and torsion during the construction process is particularly important. If the torsion and verticality of the bunker wall occurs, it will affect the quality of the construction project, and it will also change the stress state of the structural steel bars, thereby bringing quality to the project. Hidden dangers. The next step is to analyze the reasons for the torsion of the coal bunker slipform construction!

1,The assembly quality of the sliding mold device is not good enough

The assembly quality of the slipform device is the prerequisite for slipform construction. If the assembly quality is not guaranteed, there will be a tendency to twist on the platform where the sliding starts at the beginning. The main reasons are the verticality of the open frame and the climbing pole, and the truss Therefore, when the sliding mold is assembled at the beginning, a level should be used for inspection, and if any problems are found, they should be dealt with in time.

2,Uneven load distribution on the platform

This mainly refers to ensuring that the materials and equipment on the platform must be symmetrically arranged during the construction of the slipform. In addition, the use of steel bars and other materials must be used when they are hoisted.

3.Insufficient strength and rigidity of the climbing pole

After the climbing pole raw material enters the site, it shall be inspected to ensure that it conforms to the specification requirements of the construction plan. When connecting the climbing poles, make sure that the joints are concentric up and down, and take measures to strengthen the door and window openings. Generally, short steel pipes are used to strengthen the climbing poles, and the adjacent climbing poles must be reinforced laterally. The free height of the pole is not more than 500mm, so as to effectively ensure the stability of the climbing pole.

4.If the limit is not level, it is necessary to set a limiter on each climbing pole and often super-level it. After each sliding, the jack needs to withstand the limiter to keep the operating platform level as it should be state.
