Floating pipe construction device for penetrating functional pipeline in long-distance sleeve and construction method thereof

Abstract

The invention belongs to the technical field of pipeline engineering, and relates to a pipeline penetrating technology, in particular to a floating pipe construction device for penetrating a functional pipeline in a long-distance sleeve and a construction method thereof. The floating pipe construction device comprises the functional pipeline and an outer sleeve, wherein a front baffle and a back baffle are respectively installed at both ends of the outer sleeve, and the end of the functional tube in the outer sleeve is equipped with a blocking plate; after water is injected into the outer sleeve, the functional pipeline is pushed into the outer sleeve from an inlet end, then the adjacent functional pipelines are welded in sequence, and then pushed into the outer sleeve in sequence after being detected and sealed. Compared with the prior art, the device and the construction method provided by the invention have the advantages that the volume used during processing can be greatly reduced, and in addition, the volume of a traction mechanical device can be reduced, so that the pipe penetrating difficulty is simplified, and the pipe penetrating efficiency is also improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline engineering, and relates to a pipeline threading technology, in particular to a floating pipeline construction device and a construction method for a long-distance casing penetrating a functional pipeline. Background technique [0002] With the accelerated development of urban construction, it is more and more common to install casings when constructing various pipe networks (water supply pipes, gas pipes and other functional pipes) in cities to cross existing roads and densely populated areas. Due to the narrow construction area inside the casing, the long distance and heavy weight of the functional pipelines, the transportation, connection and installation of functional pipelines are greatly restricted, and flow operations cannot be carried out, which greatly reduces work efficiency. For example: the original DN1500 concrete pipe is pierced with a DN800 plastic-coated steel pipe. The original c...

Due to the narrow construction area in the casing, the long distance and heavy weight of the functional pipelines, the transportation, connection and installation of functional pipelines are greatly restricted, and flow operations cannot be carried out, which greatly reduces work efficiency

For example: DN800 plastic-coated steel pipes are worn inside the original DN1500 concrete pipes. The original construction plan is that the installation controls in the concrete pipes are narrow, and a large number of machines are required for construction on both sides. The construction is difficult and expensive.
