The long cylinder of small identical helical form is simultaneously fully inserted into the end of pipeline to be sealed, and liquid foamable polymeric resin is noted by glue rifle
Foam to form macromolecule resin seal section in the position for entering the supporting network of long cylinder.
Further, the width of supporting network to reserve between the two adjacent rings supporting network of long cylinder more than the thickness of supporting network
There is the space for accommodating liquid foamable polymeric resin.
Further, supporting network is steel wire or the plastic wire with certain degree of hardness.
Further, bunch of cables is formed by one or more cable is arranged in parallel.
It is supporting network of the both ends with sponge is tight along the outside of bunch of cables during installation using the technical solution of the utility model
The close long cylinder of internal diameter size identical helical form for being rolled into outer end diameter and pipeline to be sealed is simultaneously fully inserted into the end of pipeline to be sealed
In portion, the both ends of long cylinder are brought into close contact for the sponge of sponge and two adjacent rings, and the sponge at both ends, which forms plugging structure, prevents liquid
Macromolecule foaming resin flows out, and the position that liquid foamable polymeric resin injects the supporting network of long cylinder by glue rifle foams to be formed
Seal section, the length of seal section is accurately controlled by controlling the distance of supporting network between the sponge of both ends, ensure sealing effect
Fruit, and also avoid excessive liquid foamable polymeric resin from flowing into pipeline to be sealed and make when pipeline to be sealed is long
It is incomplete into wasting or filling.And to form an independent sky between the sponge of both ends because both ends sponge forms closure
Between, the interference of ponding in pipeline to be sealed can be avoided so that underground cable sealing structure of the present utility model there can be product
Constructed in the case of water so that seal construction is not limited by ponding, ensures being smoothed out for construction, and it is new to increase this practicality
The environmental suitability of the underground cable sealing structure of type.Meanwhile underground cable sealing structure of the present utility model also has structure
Simply, the characteristics of easy to implement and practical.
