description | The invention discloses a construction method for quickly breaking and dismantling a masonry arch bridge based on bridge deck cutting, which comprises the following steps of: 1, collecting or actually measuring structural parameters of the masonry arch bridge to be broken and dismantled, and acquiring span, rise, bridge deck pavement thickness, width and steel bar arrangement condition; step 2, cutting the to-be-broken masonry arch bridge deck, wherein the cutting position at least comprises bridge deck pavement right above an arch foot on one side; thirdly, a long-arm hook machine is adopted for breaking and dismantling an arch foot on the other side of the masonry arch bridge, and the whole span of the masonry arch bridge collapses and falls off; and fourthly, the collapsed and fallen masonry materials are cleared and transported, and masonry arch bridge forcible entry operation is completed. According to the method, the whole-span collapse can be realized, the masonry material is crushed into small blocks |
