Description
Technical field
The present invention relates to a kind of PCCP pipe joint caulking joint construction methods, belong to large-scale water delivery engineering technical field of construction.
Background technique
Using in the large-scale water delivery engineering construction of PCCP pipe, carrying out pressure detecting to mounted PCCP pipeline is to guarantee pipe
The essential step of road installation quality, bulge test must be carried out to interface after pipeline backfill for the third time by suppressing, and pressure experiment value is
Design value+0.3Mpa, and pressure stabilizing 2min, pressure value do not fall to qualification.In actual test, part PCCP pipeline is suppressed for the third time
Pressure value, which occurs, in interface reduces phenomenon, does not reach design requirement, analyzing its reason mainly has the following:
1, winter freeze thawing phenomenon leads to part PCCP pipeline cushion rubber contraction distortion, and non-reversible deformation occurs.
2, micro- sedimentation, which occurs, for pipeline foundation causes cushion rubber to misplace, and does not have sealing function.
3, for the first time, suppress for the second time during, experimental pressure is excessively high, and cushion rubber is caused to deform.
If carrying out changing Guan Congxin backfill cost prohibitive, complex process, urgent need proposes a kind of PCCP pipe joint caulking joint construction
Method solves third time and suppresses unqualified situation.
Summary of the invention
The present invention is to solve PCCP pipe third times to suppress underproof technical problem, and a kind of PCCP pipeline provided connects
Mouth caulking joint construction method, the specific implementation steps of the method are as follows:
Carry out multiple pressure to underproof PCCP pipe joint is suppressed for the third time, multiple pressure pressure by design conditions+0.3MPa into
Row is suppressed, pressure stabilizing 2min not pressure release, and it is qualified to determine, such as still unqualified, then is handled with pipe internal vibration renovation technique, i.e. method
One: multiple hydraulic water is changed into vegetable oil, so that the lubrication of cushion rubber resets.Multiple pressure pressure presses design conditions+0.3MPa, reaches rule
After level pressure force value, PCCP inner wall of the pipe female end side tapping with wooden mallet, does circumferential percussion, multiple pressure is examined again, and it is such as qualified, change
Multiple pressure is carried out with water, is reached after authorized pressure value (design conditions+0.3MPa), pressure stabilizing 2min, no pressure release, then can determine that close
Lattice, reparation terminate.
It is as unqualified in still pressed again for 5 times repeatedly, then determine that the interface peripheral doses measure is failed, it is close to use two-component polysulfide instead
Sealing processing scheme is handled, i.e. method two: using 2.5cm two-component polysulfide sealant is injected in seam, interface is remaining
Part pours into mortar, and the method that interface surface brushing SK hand scrapes polyureas composite tyre base fabric is handled.
