Problems solved by technology

[0003] In the prior art, asphalt linoleum is generally used for filling pipelines at home and abroad, and steel sealing plates are used for full welding and sealing on the upstream side. The sealing plates are easily corroded. In addition, pipeline vibration will damage the steel sealing plates and weld cracks, resulting in seepage. Leakage; and boiled asphalt linseed has great environmental pollution

Abstract

The invention belongs to the technical field of pipeline culvert filling water prevention and seepage prevention, and particularly relates to a pipeline culvert filling method. The pipeline culvert filling method comprises the procedures of pipe opening cleaning, mounting of a water-swelling sealing rod, filling and hitting of asbestos cement and polysulfide sealant plugging. The water-swelling sealing rod is hit to the middle of a circular seam between a preburied sleeve and a formal pipeline, and the total length of the water-swelling sealing rod mounted between the preburied sleeve and the formal pipeline in a hit manner is not smaller than 60 mm. The space, on the two sides of the water-swelling sealing rod, of the circular seam is filled with asbestos cement filler, the circular seam of a certain length is preserved to be filled with a polysulfide sealant after an upstream face and a downstream face are filled with the asbestos cement filler, and after the polysulfide sealant is used for plugging and acceptance is achieved, inundating or backfilling starting work can be carried out. The method can be used for culvert filling work of the clearances between the preburied sleeves and the formal pipelines of all structures, and the water prevention and seepage prevention quality is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline filling waterproof and anti-seepage, and in particular relates to a pipeline filling method, which is used for filling the gap between the pre-embedded casings of various structures and formal pipelines, and improves the waterproof and anti-seepage quality. Background technique [0002] Waterproof and anti-leakage of pipeline filling has always been a weak point in the industry. Looking at all pipeline construction regulations, there are no strict and unified requirements for this. The coexistence of various construction methods has brought "ten blocks and nine leaks" vicious circle. [0003] In the prior art, asphalt linoleum is generally used for filling pipelines at home and abroad, and steel sealing plates are used for full welding and sealing on the upstream side. The sealing plates are easily corroded. In addition, pipeline vibration will damage the steel sealing plates and weld cracks, res...
