Slippage launching method of girder on pushing and splicing platform in pushing construction

The present invention relates to a method of pushing the skid of the main beam construction method of pushing on the top platform of the pushing assembly, the pushing assembly are disposed on the top surface of the platform slide long, short chute, chute length, are located a short chute a friction sliding movement of the slider means, sliding friction slide pointing device, the main beam moves down the slider a friction sliding means, sliding friction on the slide pointing means urging force at the top, to achieve the main beam long and short forward on the slide. According to the structural characteristics of the pushing assembly platform, mechanical characteristics, while using a friction sled point method and a slider sliding frictional sliding movement of the single point method pushing operation. The present invention, by moving the slide friction sliding manner with the slide friction sliding manner a single point simultaneously, reducing the number of operators, with only a single point of moving the slider device can be realized sliding friction slip, No sync problems, and easy parking operation.
