The utility model relates to a pipeline is salvageed and is used caisson, box including the upper plate II of the upper plate I, the perpendicular to pipeline that are on a parallel with the pipeline, be on a parallel with the hypoplastron I of pipeline and the hypoplastron II of perpendicular to pipeline, upper plate I connects gradually with upper plate II and forms box saddle, hypoplastron I connects gradually with hypoplastron II and forms box lower part frame, between upper plate I and the hypoplastron I, correspond respectively between upper plate II and the hypoplastron II and link together, be equipped with the baffle on the hypoplastron II of perpendicular to pipeline, the bottom of box is equipped with end support. By adopting the above structure, the utility model, can guarantee that marshland or desert area when salvageing the pipeline operation, make the hole take shape fast, satisfy the emergency repair demand. And simultaneously, the utility model discloses simple structure, convenient operation, it is with low costs, be suitable for popularization and application.
