Abstract
The utility model relates to a buried pipeline repair device which comprises a steel plate sleeve ring and fillings. The steel plate sleeve ring is arranged inside a pipeline broken position. The fillings are arranged between the pipeline and the steel plate sleeve ring. The outer diameter of the steel plate sleeve ring is smaller than the inner diameter of the pipeline. The steel plate sleeve ring is formed by more than two splicing units. One ends of the splicing units are provided with grooves and the other ends of the splicing units are provided with convex heads. Sealing bars are arranged inside the grooves. The fillings are polyurethane foam rubber. Due to a buried pipeline non-excavation repair technology, the buried pipeline repair device is capable of achieving corrosion prevention and repair of the buried pipeline, fast in construction time, stable and reliable in quality, simple and practicable in repair process, suitable for repair of pipelines with a large diameter, and capable of saving manpower, material resources, and financial resources.
Description
Technical field
The utility model relates to the pipeline rehabilitation field, relates in particular to a kind of buried pipeline repairing device.
Background technique
In the metallurgy industry construction, buried pipeline seepage and corrosion-resistant reparation are an extremely important and difficult job always.At present, what generally adopt is the destructive method of construction of excavating, and floor space is large, and labor intensive, material resources are all very huge.And utilize the non-excavation pipe rehabilitation technology of buried pipeline to realize anticorrosion to buried pipeline and reparation, and not only save human and material resources, financial resources, but also shortened the duration.Existing common method is slip casting method, both stops up seepage by grouting in soil mass outside interface position and pipe, and this kind method is blindness relatively, and reliability ratio is relatively poor.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of buried pipeline repairing device, and simple in structure, easy to use, repairing quality is more stable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of buried pipeline repairing device comprises the steel plate collar, stuffing, is provided with the steel plate collar in inside, piping failure place, is provided with stuffing between pipeline and the steel plate collar, and described steel plate collar external diameter is less than internal diameter of the pipeline; The described steel plate collar is comprised of two above concatenation units, and concatenation unit one end is provided with groove, and the other end is provided with plush copper, is provided with Stamping Steel Ribbon in the groove; Described stuffing is polyurethane foam glue.
Compared with prior art, the beneficial effects of the utility model are:
Utilize the non-excavation pipe rehabilitation technology of buried pipeline to realize anticorrosion to buried pipeline and reparation, speed of application is fast, and steady quality is reliable, and repair process is simple, and suitable large diameter pipeline is repaiied, and saves human and material resources, financial resources.

Embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 1-Fig. 4, a kind of buried pipeline repairing device comprises the steel plate collar, stuffing 2, is provided with the steel plate collar in pipeline 1 breakage spot inside, is provided with stuffing 2 between pipeline 1 and the steel plate collar, and described steel plate collar external diameter is less than pipeline 1 internal diameter; The described steel plate collar is comprised of two above concatenation units 3, and concatenation unit 3 one ends are provided with groove 4, and the other end is provided with plush copper 5, is provided with Stamping Steel Ribbon 6 in the groove 4; Described stuffing 2 is polyurethane foam glue.
When carrying out pipeline rehabilitation work, damaged pipe 1 is cleaned out, and inwall is carried out grinding process, make the steel plate collar according to the impaired place internal diameter of damaged pipe 1, the external diameter of concatenation unit 3 is less than the internal diameter of impaired place pipeline 1, and the steel plate collar is made smooth advances in the damaged pipe 1.With concatenation unit 3 splicings that process, groove 4 snaps in Stamping Steel Ribbon 6, plush copper 5 splicings with another concatenation unit, then successively a plurality of concatenation units 3 are headed into damaged pipe 1, between damaged pipe 1 and the steel pipe collar that formed by concatenation unit 3, inject stuffing 2 with slip casting machine, stuffing 2 can be polyurethane foam glue, and pipe-repairing was complete after stuffing solidified, the site clearing.
The utility model utilizes the non-excavation pipe rehabilitation technology of buried pipeline to realize anticorrosion to buried pipeline and reparation, and speed of application is fast, and steady quality is reliable, and repair process is simple, and suitable large diameter pipeline is repaiied, and saves human and material resources, financial resources.
