routine maintenance and upkeep of box girder formwork

1. Do a good job of cleaning and checking before each use.

2, the outer mold need to check whether the spiral support is in a state of stress, all parts of the deformation, whether the bolt connection is normal, whether there is no fall off. Once found should be excluded in time.

3, the inner mold need to check to determine whether the cylinder and all parts of the hinge pin connection is normal, there is no shedding, tampering with the hydraulic system, there is no leakage, there is no damage to the oil pipe and other phenomena. Once found should be promptly excluded.

4、Check whether the foundation settles, whether the welding between the base mold and the pedestal is firm.

5. The internal formwork must be operated, maintained and maintained by special personnel. The bearing and support screw in each running wheel are lubricated with calcium base grease (SYB140-65), generally once every 7-15 days. Always keep the electrical equipment and hydraulic components clean to prevent leakage, breakdown, short circuit, valve plug blockage and other phenomena. The hydraulic medium must be of the specified type and have the corresponding viscosity. During the operation of the hydraulic system, check the blockage of the oil filter at any time and clean or replace it in time.

6, if the use of winch traction into the mold, the need for regular lubrication of the winch traction wire rope (each work cycle), lubrication before the removal of dirt, where found that the wire rope broken more than 5, should be immediately scrapped and renewed to avoid causing accidents.
