Description
Technical field
The present invention relates to technical field of building construction, particularly a kind of construction method of super high rise building piping shaft interior conduit and device.
Background technology
In technical field of building construction, super high rise building refers to the building of more than 40 layers or height more than 100 meters.Building is provided with piping shaft, and piping shaft is for arranging the vertical hoistway of vertical equipment installation in building.Pipeline in piping shaft comprises all multi-pipelines of water supply, power supply, draining, phone, cable television, monitoring, network, ventilation etc.In prior art, the construction method of pipeline, utilize tower crane to be that the prover section of 6 meters to 9 meters is lifted into corresponding floor by length, after again prover section being cut into the shorter pipeline section of such as 2 meters to 3 meters, upwards successively welded in piping shaft successively by the bottom of floor, to complete the construction operation of pipeline.After being cut by prover section, the length of pipeline section shortens, when welding for every layer, until after the weld job of top layer pipeline completes, the weld bond of whole pipeline is more, causes the welding quality of pipeline relatively poor; And the limitation in space due to piping shaft, when welding the pipeline section of smaller length, often due to the restriction of the narrow space of piping shaft, cause occurring the phenomenon such as solder skip, dry joint between two adjacent pipeline sections, add the breakthrough of pipeline thus in the weld locations of adjacent two pipeline sections, cause serious defect to the quality of the pipelines such as water supply, power supply, draining, phone, cable television, monitoring, network, ventilation.
Summary of the invention
