Pipeline sand blasting backfilling device
The invention discloses a pipeline sand blasting backfilling device, and belongs to the technical field of engineering flood control devices. The pipeline sand blasting backfilling device comprises asand blasting main pipe, one side of the sand blasting main pipe is connected with a guide pipe in an intercommunicating manner, a flange plate A is welded at the top end of the guide pipe, and a knife gate valve is detachably connected between the flange plate A and a flange plate B; the flange plate B is welded to the head end of a pipe body of the sand guiding pipe, the rear end of the pipe body of the sand guiding pipe is sleeved with a pipe bundle cloth bag, flange plates C are welded to pipe openings in the two ends of the sand blasting main pipe, an inner pipe is arranged in the middleof each flange plate C of the sand blasting main pipe, and the flange plates C are connected with flange plates D of the external pipes and then locked through bolts. At the moment, the inner pipes penetrate through the flange plates D and then are attached to the inner wall of an external pipe, clamping rings on the outer side of the inner pipes are connected into notches in the inner walls of the flange plates D for sealing, and the connection sealing performance between the sand blasting main pipe and the external pipe is optimized through embedded sealing structures such as the inner pipesand the clamping rings.
本发明公开了一种管道吹砂回填装置，属于工程防洪装置技术领域，包括吹砂主管，所述吹砂主管的一侧互通连接有导管，且导管的顶端焊接有法兰盘A，所述法兰盘A和法兰盘B之间可拆卸连接有刀闸阀，且法兰盘B焊接于引砂管的管体首端，所述引砂管的管体后端套接有管排布袋，所述吹砂主管的两端管口处焊接有法兰盘C，在吹砂主管的法兰盘C中部设置内管，法兰盘C与外接管的法兰盘D衔接后使用螺栓锁紧，此时内管穿过法兰盘D后贴合于外接管的内壁处，而内管外侧的卡环衔接于法兰盘D的内壁槽口中进行密封，通过内管和卡环等嵌合密封结构优化吹砂主管与外接管之间的连接密封性。
