a.拉杆加固法，它是采用钢彩、套管加固，通常使用在500Pa以下的正压加固。
A. pull rod reinforcement method, it is steel color and casing reinforcement, usually used under 500Pa positive pressure reinforcement.
b.框架加固法，即采用轻钢龙骨加固。
B. framework reinforcement method, that is, the use of light steel keel reinforcement.
c.抱合加固法，即采用轻钢龙骨加固，使用在拉杆加固和框架加固无法应用的某些特殊管道上，如900弯管、三通管、闷头管等。
C. consolidation method, which is reinforced by light steel keel, is used on some special pipes which can not be applied in the reinforcement of the rod and the frame reinforcement, such as the 900 bend pipe, the three pipe, the head pipe and so on.
d.防下垂加固法，它用于特殊管道的加固，如变经管道加固和迂回管道加固。如果是管道外表面很轻微的破损，可以用专用的密封胶带来进行修补即可。
D. anti droop reinforcement method, it is used for reinforcement of special pipelines, such as reinforcement of pipeline and reinforcement of bypass pipes. If the outer surface of pipeline is very slight, it can be repaired with special sealing tape.
如果是管道内表面有轻微破损，则可用舒伯专用修补胶进行修补。如果管道外表面的铝箔层发生破损，而玻纤保温层未发生损坏，则可选用一片合格的铝箔片进行管道铝箔表面的修补。
If the inner surface of pipeline is slightly damaged, it can be repaired with special repair glue. If the aluminum foil layer on the outer surface of the pipe is damaged and the glass fiber insulation layer is not damaged, a piece of qualified aluminum foil can be used to repair the aluminum foil surface of the pipeline.
如果管道壁的破损已达到玻纤保温层时，则可将破损的地方切割下来，开出雌雄搭接口，另选一块完好的板材，根据切割下来的玻板尺寸切割好，留下雌雄搭接口，在四周接口上涂上修补胶及粘胶剂，根据工艺规范进行密封。
If the breakage of the pipe wall has reached the glass fiber insulation layer, the damaged place can be cut down, the female and male joint interface is opened, and a good sheet is selected. The cut off glass plate size is cut well, the male and female joint interface is left, the repair glue and adhesive are coated on the surrounding interface, and the seal is sealed according to the technical specification.
