The rearing structures proposed by the utility mode are mainly used for repairing various underground pipelines.
Description
Technical field
The stainless steel-lined pipe-repairing structure that is used for underground old pipeline rehabilitation that the utility model proposes belongs to the pipe rehabilitation technology field, specially refers to the lining of stainless steel lining pipe as old pipeline.
Background technique
Have to the modern chemical industry industrial city pipelines such as the staggered oil of longitudinal mode, vapour, water supply and sewage, electric power, communication, these pipelines old pipeline after long-time running will upgrade or repair, so that recover the function of pipeline.
The existing pipe-repairing structure of the old pipeline of being made by materials such as steel pipe, cast iron tube, plastic tube, Glass Steel Tube, cement pipe is that the cured layer that is formed by nonmetallic material such as slush, various plastics, resin mortar, rubber is set on the inwall of old pipeline, this pipe-repairing structural strength is low, lack working life, medium especially water is had secondary pollution, do not satisfy modern people's requirement.
The model utility content
In order to overcome the above-mentioned deficiency in the background technique, the purpose of this utility model is the pipe-repairing structure of the stainless steel lining pipe of long old pipeline of a kind of high quality of proposition, life-span.
The pipe-repairing structure of this stainless steel lining pipe is:
1, a kind of pipe-repairing structure that is used for the stainless steel lining pipe of underground old pipeline rehabilitation is characterized in that,
When the internal diameter size of old pipeline 1-1 equaled or is approximately equal to the outside dimension of stainless steel lining pipe 1-2, this structure was that stainless steel lining pipe 1-2 two ends are being welded to connect stainless steel short circuit head 1-4, and its outside is old pipeline 1-1, is binder 1-3 between two pipes;
When the internal diameter size of old pipeline 2-1 during greater than the outside dimension of stainless steel lining pipe 2-2, this structure is the inner stainless steel lining pipe 2-2 that is, its outside is old pipeline 2-1, be some equidistant card 2-5 and binder and bulking agent 2-3 between two pipes, also be provided with injecting hole 2-6 and air outlet hole 2-7 on the old pipeline 2-1.
2, in above-mentioned pipe-repairing structure, can be according to the seal request difference of pipe-repairing without stainless steel short circuit head 1-4.
3, in above-mentioned pipe-repairing structure, different according to old pipeline 1-1,2-1 with the size of stainless steel lining pipe 1-2,2-2, can be without binder 1-3,2-3.
4, in above-mentioned pipe-repairing structure, because stainless steel lining pipe 3-2 is different with the size of old pipeline 3-1, can adopt the inner eccentric stainless steel lining pipe 3-2 that is, the outside is old pipeline 3-1, is the pipe-repairing structure of bulking agent 3-3 between two pipes.
5, in above-mentioned pipe-repairing structure, old pipeline 1-1,2-1,3-1 can be a kind of in steel pipe, cast iron tube, plastic tube, Glass Steel Tube, the cement pipe; Can replace stainless steel lining pipe 1-2,2-2,3-2 with one of anti-corrosion titanium, aluminium, nickel, Cu metal tubes.
The old pipeline rehabilitation structure that the soft lining method of the pipe-repairing structure of the stainless steel lining pipe that the utility model proposes and existing usefulness forms compare have the intensity height, long service life, to the medium especially advantage of water no secondary pollution.
The pipe-repairing structure that the utility model proposes is mainly used in the reparation that is embedded in underground various pipes.
Description of drawings
The internal diameter size of Fig. 1, old pipeline equals or the pipe-repairing structural drawing when being approximately equal to stainless steel lining external diameter of pipe size;
The pipe-repairing structural drawing of the internal diameter size of Fig. 2, old pipeline during greater than stainless steel lining external diameter of pipe size;
Fig. 3, stainless steel lining pipe off-centre are in old ducted pipe-repairing structural drawing.
The pipe-repairing structure that the utility model proposes below in conjunction with description of drawings.
Fig. 1 represents is that the internal diameter size of old pipeline 1-1 equals or the pipe-repairing structure when being approximately equal to the outside dimension of stainless steel lining pipe 1-2.In this structure, the outside is old pipeline 1-1, and inside is stainless steel lining pipe 1-2, is binder 1-3 therebetween, and the two ends of stainless steel lining pipe 1-2 and stainless steel short circuit head 1-4 are welded to connect.
Fig. 2 represents is the internal diameter size of the old pipeline 2-1 pipe-repairing structure during greater than stainless steel lining pipe 2-2 outside dimension, in this structure, the outside is old pipeline 2-1, inside is stainless steel lining pipe 2-2, be some equidistant card 2-5 and binder and bulking agent 2-3 therebetween, also be provided with injecting hole 2-6 and air outlet hole 2-7 on the old pipeline 2-1.
Fig. 3 represents is a kind of pipe-repairing structure among the old pipeline 3-1 of being in of stainless steel lining pipe 3-2 off-centre, in this structure, inside is eccentric stainless steel lining pipe 3-2, the outside is old pipeline 3-1, be bulking agent 3-3 therebetween, the pipe-repairing structure of this off-centre mainly is to adopt when the size of old pipeline 3-1 and stainless steel lining pipe 3-2 differs big.
In above-mentioned structure shown in Figure 1, because the seal request difference of pipe-repairing can be without stainless steel short circuit head 1-4.
In above-mentioned structure illustrated in figures 1 and 2, because old pipeline 1-1,2-1 are different with the size of stainless steel lining pipe 1-2,2-2, can not all right binder 1-3,2-3.
