2. When applying pre-pressure, a pressure meter shall be placed at the contact between the top post of the jack and the steel pipe to control the pre-pressure.

3. After the installation of the steel shoring prop, both ends should be reinforced to prevent the steel prop support from deviating from the axis.

4. The wedge should be checked regularly, and the stress should be re-applied if the wedge is loose, so as not to lose the effectiveness of the support.

5. The bolts must be fastened when riveted.

6. After the steel purlin is installed, the rear of the purlin and the pile should be filled with 40℃ fine stone concrete in time.
