Abstract

The invention relates to the technical field of pipeline through-wall culvert filling, in particular to a pipeline through-wall culvert filling construction process which comprises five steps. According to the pipeline through-wall culvert filling construction process provided by the invention, the design is ingenious, the materials are exquisite, the overall installation is simple and convenient, the construction difficulty is reduced, the construction progress is accelerated, a wall bushing is sleeved at the joint of a pipeline and a wall body, and a supporting steel plate is matched to play a better protection effect on a foaming filler, so that the leakage caused by the extrusion deformation of the foaming filler under the gravity action of the pipeline and the shaking of the pipeline is avoided; meanwhile, the foaming filler has waterproof, anti-aging and compression-resistant performance and is long in service life, asbestos cement has rigidity after being cured as a second waterproof seal, the position of the pipeline can be fixed, the situation that the foaming filler is extruded, deformed and torn due to displacement and shaking of the pipeline is prevented, and the protection performance is improved; and a weather-resistant sealant added with silicone has the advantages of good elasticity, strong binding power, aging resistance and strong sealing performance, and further improves the anti-leakage effect.

Description

technical field

[0001] The invention relates to the technical field of pipeline wall filling and culverting, in particular to a pipeline wall filling and culvert construction process. Background technique

[0002] With the development of society and the needs of the city's appearance, the original water pipelines on the ground are transformed into hidden lines and buried underground. In order to reduce the difficulty and cost of construction, it is usually necessary to pass the pipelines through the wall to reduce the laying of lines.

[0003] However, the leakage of the buried pipeline through the wall is a common quality problem in building construction. The seal between the buried pipeline through the wall and the pipeline has two situations: leakage after construction and leakage after a certain period of operation. The cause analysis Nothing more than the following reasons: 1. The sealing material selected in the design is unreliable; 2. The construction method selected...
