[0064] Based on the above-mentioned packing method of the modular storage and transportation container for the combat steel bridge, that is, the packing sequence of two sections of the combat steel bridge in one storage and transportation container is as follows:

[0066] The second step is to control the manual hydraulic lifting roller B8 to be in the jacking state through the manual hydraulic pump 27, that is, the upper surface formed by two or more manual hydraulic lifting rollers B8 is higher than the upper surface formed by the truss cross bar 7, and the manual hydraulic lifting roller B8 plays a temporary supporting role;

[0067] The third step is to refer to the appendix Figure 2 , after pre-splicing eight truss sheets 18 and sixteen reinforcing chord bars 17, place them on the manually hydraulic lifting roller B8 in the jacking state through the opened end door, and push the truss sheets 18 and the reinforcing chord bars 17 into the truss placement rack of the storage and transportation container through the rolling manual hydraulic lifting roller B8, and each truss sheet 18 is respectively located between two adjacent truss cross bars 7 of the truss placement rack; the rolling of the manual hydraulic lifting roller B8 can reduce the frictional resistance of the truss sheets 18 and the reinforcing chord bars 17 during packing, and facilitate the packing of the truss sheets 18 and the reinforcing chord bars 17.

[0068] Step 4: Control the manual hydraulic lifting roller B8 of the manual hydraulic pump 27 to relieve pressure, that is, the upper surface formed by two or more manual hydraulic lifting rollers B8 is no longer higher than the upper surface formed by the truss cross bar 7. The truss piece 18 and the reinforcing chord 17 are supported on the cushion block 9, which can prevent the manual hydraulic lifting roller B8 from being deformed due to long-term compression;

Through the rolling manual hydraulic lifting roller A2, push the four cross beams 19 into the two columns 3 of the cross beam placement rack in the storage and transportation container. The rolling of the manual hydraulic lifting roller A2 can reduce the frictional resistance of the cross beam 19 during boxing;

[0070] After the four cross beams 19 are pushed to the set position, control the manual hydraulic lifting roller A2 of the manual hydraulic pump 27 to relieve pressure, so that the four cross beams 19 are respectively supported on the corresponding angle steels 4;

[0071] Step 6: Refer to the appendix Figure 4 , control the manual hydraulic lifting roller C13 of the upper layer spacer to be in the jacking state through the manual hydraulic pump 27 to reduce the frictional resistance during the boxing process of each component;

[0072] If there is an end segment in the two segments, first install the end columns 23 on the upper layer spacer: After bundling and packing the eight end columns 23 in two groups side by side, hoist them to the upper layer spacer and place them at one end on the manual hydraulic lifting roller C13. Push the end columns 23 into the storage and transportation container through the rolling manual hydraulic lifting roller C13 and place them above the frame body 12 of the upper layer spacer;

[0073] Step 7: Divide every four standard bridge decks 21 into a group, and then hoist the two groups of standard bridge decks 21 as a whole to the upper layer spacer and place them at the other end on the manual hydraulic lifting roller C13. Push the standard bridge decks 21 into the storage and transportation container through the rolling manual hydraulic lifting roller C13 and place them above the frame body 12 of the upper layer spacer;

[0074] Step 8: Hoist the two middle bridge decks 20 and the four curb stones 22 on the middle bridge decks 20 as a whole to the upper layer spacer and place them at the other end on the manual hydraulic lifting roller C13. Push the two middle bridge decks 20 into the storage and transportation container through the rolling manual hydraulic lifting roller C13 and place them above the frame body 12 of the upper layer spacer, and at the same time place them between the two groups of standard bridge decks 21;

[0075] Step 9: Hoist the wind-resistant tie rod 24 to the upper shelf and place it at the other end on the manual hydraulic lifting roller C13. Push the wind-resistant tie rod 24 into the storage and transportation container through the rolling manual hydraulic lifting roller C13. The wind-resistant tie rod 24 should be located above the frame body 12 of the upper shelf and at the same time in the gap between the standard bridge deck 21 and the middle bridge deck 20.

[0076] Step 10: After all the components on the upper shelf are packed, control the manual hydraulic pump 27 to relieve the pressure of the manual hydraulic lifting roller C13, so that the end columns 23, the standard bridge deck 21, the middle bridge deck 20 and the wind-resistant tie rod 24 are all supported on the frame body 12 of the upper shelf.

[0077] Step 11: Install the diagonal braces 14 and the support frames 16 on the diagonal brace fixing device 1 and the cross brace fixing device 5 respectively.

[0078] Step 12: Refer to the appendix Figure 3 , pack the standard parts of the two segments into the two toolboxes 15 respectively, and install the two toolboxes 15 in the bolt holes 25 of the bottom plate through bolts.

[0079] Step 13: Close the two end doors to complete the packing of the two segments and the two toolboxes 15.
