Slide-to-position method for large earth-covering bullet pot

The invention provides a slide-to-position method for a large earth-covering bullet pot. The method comprises the following steps: S1, according to a planning design of a sand bed, calculating the fall between the elevation of a field installed and welded region and the elevation of the bullet pot in position on the sand bed, and designing the height, to which the bullet pot needs to be jacked; S2, performing a jacking operation: jacking the earth-covering bullet pot to the field installed and welded region to the designed height by using a jacking bracket; S3, sliding the bracket to position: after the earth-covering bullet pot is jacked to the designed height, transferring the bullet pot to a slide bracket on a slide rail, and jacking the slide bracket till the elevation of the bullet pot exceed the minimum passage height of the sand bed; S4, horizontally pushing and sliding: pushing the bullet pot to the corresponding designed position on the sand bed by using a pushing device; and S5, enabling earth-cover
