Abstract: The caisson is shipped by airbags to carry heavy parts. The essence is to place a special rubber airbag under the caisson, and then inflate and pressurize the caisson to lift the caisson, and then use the hoist and pulley block to apply enough to the caisson in the direction to be moved. Traction, under the action of traction, the caisson produces friction on the airbag, so that the airbag rolls and moves forward together with the caisson. In the forward direction of the caisson, the operator should follow up the laying and inflation of the airbag in time. Based on this, on the basis of summarizing the construction technology of airbag shipping caisson, further standardizing the construction technology of airbag shipping caisson, ensuring the quality of the project, and guiding the construction and monitoring management.
