Safety and anti-corrosion measures for shield walkway board:
1. The walkway board shall be painted with anti-rust paint;
2. The weld is full;
3. It is strictly forbidden to stack more than 150Kg in a concentrated way, to jump on the walkway board, to pass the old, weak, sick and disabled, and to keep the distance between pedestrians less than 1m; 4. The handrail shall be designed according to the regulations, and the height of the handrail shall not be less than 1.2 meters;
5. When connecting with segment bolts, the bolts shall not be damaged, and the nuts shall be tightened;
6. The walkway board and its connection shall be included in the daily safety inspection of the project. In case of excessive deformation or damage, it shall be repaired or replaced in time
The tunnel walkway plate is easy to use in the shield construction of subway tunnel, with strong bearing capacity, and can be reused. It is welded from high-quality low-carbon steel plate. The surface is uniform, the metal wire rod is firm and not easy to deform. The mesh surface is flat, the surface is anti-skid, wear-resistant, with large bearing capacity and strong pressure resistance.
Main force transmission path: pedestrian load - steel plate stamping mesh - angle steel (channel steel) - flat iron - segment bolt - shield segment
Surface treatment: red or yellow epoxy antirust paint, full weld, full weld between angle steel and angle steel. It is forbidden to stack more than 150kg in a concentrated way.
