Description
Technical field
This utility model belongs to stainless steel tube field, especially relates to a kind of be provided with the thin-walled liner steel tube that blind plate is stifled
Road.
Background technology
Underground piping is one of big event in China's economic construction.Found the state and over 60 years, add up the ground of laying more than 380,000 kilometer
Lower water supply line, major part has arrived the military service end of term, and some discovery leakage rate of water supplies reach about 20%, this partly underground pipelines anxious
Reparation need to be updated.At present, along with expanding economy, the scale of domestic city is increasing, for water delivery, draining etc. need also with
Increase.Urban inner many water supply and sewerage pipelines are long neglected and in disrepair, leak serious, have as source water pipeline, if again laying
Duration is longer, and earth clearance intricate operation.Internal lining cutting thin-wall stainless steel or steel pipe is used to repair damaged pipe,
There is increasing engineer applied.However, to ensure that conveyance power of water, rustless steel and steel pipe all use sheet-metal duct to carry out liner,
Therefore when sheet-metal duct is suppressed, at blind plate and compare weak with trocar sheath joining place, it is therefore desirable to special blind plate blocks up.At present
There is no the blind plate suppressed for thin-walled liner steel pipe both at home and abroad to block up.
Summary of the invention
In view of this, this utility model is directed to a kind of thin-walled liner steel pipe blind plate and blocks up, and can solve above-mentioned asking
Topic.
For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that
A kind of it is provided with the thin-walled liner steel pipe that blind plate is stifled, including steel pipe, concrete sleeve, positioning pipe, connecting tube, method
Blue dish and blind plate, described positioning pipe and connecting tube are made up of integrated steel plate, and positioning pipe is fixed on the end of concrete sleeve
Portion, connecting tube is connected between ring flange and concrete sleeve, and the external diameter of connecting tube wherein one end is more than the external diameter of the other end, even
Take over thinner one end and be fixedly welded on the edge of ring flange, be bolted between blind plate and ring flange.
Further, described positioning pipe being evenly equipped with hole, some location, rivet is fixed on concrete sleeve by hole, location
End.
Further, described connecting tube is to be welded to each other after steel plate is cut into some steel bars to make again, the surface of each steel bar
Long-pending equivalently-sized.
Relative to prior art, the thin-walled liner steel pipe being provided with blind plate stifled described in the utility model has following excellent
Gesture: this special blind plate blocks up, can connect into an entirety, in the mistake carrying out bulge test by thin-walled steel internal lining pipe and trocar sheath
Cheng Zhong, make at blind plate and with trocar sheath joining place uniform force, thus smoothly complete pipeline bulge test.
