Background technique
Prestressed concrete cylinder pipe, abbreviation PCCP pipe are a kind of answering with high intensity, high permeability resistant and high leakproofness
It is former auxiliary to have gathered sheet metal, high-strength concrete, high-strength prestressed steel wire, high-strength mortar and rubber seal etc. for mould assembly tubing
Material is fabricated.The pipeline is particularly suitable for heavy caliber, senior engineer's pressure and high earthing water supply project.PCCP pipe uses bell and spigot formula
Connection is sealed by installing rubber seal at socket recess.According to code requirement, after pressure pipeline is installed,
The carry out water pressure test should be segmented just allows grid-connected water flowing to come into operation after the water pressure test is qualified (drawdown and water percolating capacity method).
The length of pipe section of the pressure pipeline water pressure test is required not to be preferably greater than 1.0km in specification, therefore Pressure Piping Engineering need to carry out repeatedly
The water pressure test.The plugging device of the water pressure test counts for much.The especially safety of plugging device, economy and invention convenience
It is all influenced on the water pressure test, even on entire pipeline installation engineering great.

It forms, general a length of 5000mm, both ends setting bell and spigot is connect with PCCP pipe.The welding of accessory tube bosom is suppressed in steel
Steel is suppressed and is blocked inside accessory tube by steel plate, as the closure plate of the water pressure test, is produced using PCCP pipe and the soil body of front and back installation
Raw frictional force prevents sliding as backrest, and a certain section of PCCP pipeline for suppressing accessory tube middle position to two section steels carries out
Bath and the water pressure test.After the completion of the water pressure test, need to be manually entered closure plate be cut into fritter inside pipeline, closure plate fritter from
After hanging out pipeline into manhole, then pipeline inside closure plate position is handled using mortar lining cutting.Therefore, steel suppresses accessory tube cost
Higher, generally thickness 20mm~30mm roll of steel plate weldering is made, and inner circular closure plate thickness 30mm~40mm is suppressed with steel and matched
The welding of part pipe, steel plate welding quality require high.It, be manually from into cutting in manhole pipe after the completion of the water pressure test, expense of taking a lot of work
When, worker carries out cutting operation inside the pipeline that air hardly circulates, and is absolutely unsafe, and endangers health.And it manually cuts
Accessory tube may also be suppressed to steel by, which cutting, the adverse effect such as is deformed.Plugging plate is welded on steel and suppresses inside accessory tube, water
Displacement or the deformation that the PCCP pipeline as rear backrest can not be observed during pressure test, cause the water pressure test to allow to seep
The test of water method is inaccurate.In addition it after the completion of the water pressure test, needs to be manually entered inside pipeline closure plate is cut into fritter, cause
Closure plate can only first use, cannot recycle, economic efficacy is low.
