Description

Broken pipe repairing device for internally inserting ground pipeline

Technical Field

The utility model relates to a crude oil gathering pipeline engineering technical field, in particular to disconnected tub of prosthetic devices that is used for interior interlude ground pipeline.

Background

In the process of crude oil exploitation, crude oil is conveyed through a metal pipeline after reaching the ground, because the crude oil extracted underground has complex components and contains corrosive substances, and the metal characteristics of the gathering and conveying pipeline inevitably cause corrosion of the gathering and conveying pipeline in different degrees, the corrosion problem causes serious harm to production, pipeline perforation causes interruption of production, and environmental pollution in different degrees and serious waste of social resources.

In order to avoid metal corrosion, glass reinforced plastic pipes are adopted to replace metal ground pipelines in some areas, although the corrosion problem is effectively solved, the glass reinforced plastic pipes do not have the strength of metal pipes, are easy to damage in the ground laying process and cannot be effectively used for a long time, and along with the implementation of the interpenetration process in the ground pipelines, PE pipes are adopted to directly penetrate through the gathering pipelines to be repaired, so that the problems of damage and the like in the construction process are solved. In the construction process, the construction pipeline is long, the PE pipe cannot directly penetrate through the whole pipeline, so that the pipe needs to be dug and broken, reducing diameters are respectively welded at two ends of the broken pipe after the pipe is broken, the PE pipe can smoothly penetrate out, then a steel wrapping sleeve with the diameter larger than that of the construction pipeline is sleeved on the construction pipeline, the PE pipe is welded through hot melting welding or a hot melting sleeve, but in the subsequent steel wrapping construction process, the welding is limited by the operation space and is slow; before and after welding, water needs to be injected and drained in steel ladle wrapping; after welding, mortar needs to be poured in the steel wrapping reserved hole, construction is complicated, construction progress is greatly prolonged, and production can not be recovered efficiently.

Aiming at repairing broken pipes, in the prior art, steel-wrapped lap welding is mainly adopted, the welding is limited by an operation space, the construction difficulty is high, the consumed time is long, in order to prevent the PE pipe and the original steel pipe from being penetrated and inserted into the space between the PE pipe and the original steel pipe to form collapse, a mortar grouting hole is reserved on the wall of the steel-wrapped pipe after welding, and the steel-wrapped pipe can be pressurized after the mortar is completely solidified (the solidification time is long according to the weather condition); during pressing, all the holes are cut if leakage exists, welding assembly is carried out again, and when error work occurs, the grouting preformed hole can be welded after pressing is qualified, so that the whole construction process is complex and tedious.

Therefore, a broken pipe repairing device which can effectively improve the construction efficiency, liberate the manpower and reduce the comprehensive construction cost is needed.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information constitutes prior art already known to a person skilled in the art.
