Description
Patent of the present invention relates to pipeline pipeline transportation art, particularly a kind of pipeline pore method for blocking and special-purpose closeouts.
The pipeline pipeline is the grid of forming with concrete pipe, pvc pipe etc.Along with urban pipe network constantly enlarges, the increase-volume of various pipelines and reconstruction have very easily caused damage in various degree to each grid, particularly underground harmful water source and harmful gas are ganged up mutually by pore, the harm that causes to pipeline facility constantly enlarges, even directly jeopardizes the normal use of personal safety and equipment.Therefore, take the necessary technology measure, prevent that harmful water source and harmful gas from ganging up mutually by pore and permeate the pore shutoff, very necessary.
Patent application of the present invention a few days ago, pipeline (communication) pore open on the market, that use belongs to open type more, harmful water source and harmful gas can be ganged up mutually by pore, even employing blocking technology, as: U.S.'s Raychem adopts plastic film--aluminium foil--plastic film multilayer materials to make the tubulose air bag of band valve, by coating adhesive sticker at its outer surface, air bag is wrapped in fills in pore on the cable, its expansion is reached stop up by inflation and leak effect.But this technology is still loaded down with trivial details at complex structure, construction process, can't reuse, defective such as poor sealing performance particularly.
The goal of the invention of patent of the present invention is to provide a kind of pipeline pore method for blocking and special-purpose closeouts of simple in structure, easy to operate, good sealing effect.
Foregoing invention purpose of the present invention realizes by following technical proposals:
A kind of pipeline pore method for blocking may further comprise the steps: (1) pore pipeline is nested with shutoff; (2) the pore gut line is passed the cross section and be the trapezoidal built-in middle through hole of circular cone plugging block; (3) cross section being trapezoidal circular cone plugging block fills in by shutoff pore, jam-pack; (4) following formula A component, B component and C component are mixed, get leakage-stop liquid D, the A component: (R ＇-OH)
NIn the formula: R ＇ is a phenyl ring or a bitter edible plant ring, the N span: 8～10, and B component: (R-NCO)
MThe carbon chain lengths of R is 6～8 C in the formula, the M span: 9～11 C components: fluorine Lyons is routine stabilizer; (5) leakage-stop liquid that leakage-stop liquid D is trapezoidal circular cone plugging block setting by the cross section is clamp-oned through hole and is annotated to be between trapezoidal circular cone plugging block and shutoff to the cross section and foam sealing.
Described step (1): the pore pipeline is nested with shutoff, and purpose is to provide with the cross section and is foaming, the curing space that trapezoidal circular cone plugging block forms leakage-stop liquid, and it is excessive to limit leakage-stop liquid, forms sealing layer, improves sealing effect.
