Problems solved by technology
[0002] With the strengthening of urban infrastructure construction, a large number of municipal water supply and drainage pipelines have been built in the city. However, due to the different ages of the current pipeline laying, in addition to the damage of the pipelines constructed in the early stage, some new pipelines are also damaged due to poor local geological conditions and other reasons. Structural and functional damage occurs, seriously affecting the safe operation of urban drainage
[0003] The traditional pipeline repair process adopts excavation repair method to remove the defective pipe section and replace it with a new pipe section. It will increase the cost of labor, materials, machinery, etc. required for ground restoration, etc., and the construction cost will be high

The invention discloses a drainage pipeline steel embracing ring repairing construction method, and relates to the field of building construction. The drainage pipeline steel embracing ring repairingconstruction method comprises the steps: a to-be-repaired area of a pipeline is pretreated, and steel plates are assembled into a steel sleeve and fixed to the to-be-repaired area to form a lining; agrouting hole is formed in the middle of each steel plate; the space between the steel sleeve and the pipeline is filled with cement paste through the grouting holes; and ultraviolet curing construction is conducted in the steel sleeve. According to the scheme, the steel plates are spliced into the steel sleeve and fixed to the construction section inspection well to form the lining, so that excavation, transportation and stacking of engineering soil can be reduced, the influence of the construction process on traffic, the environment and the like is reduced, and meanwhile, labor, materials, mechanical expenses and the like needed by ground recovery and the like are reduced, and the construction cost is low.
Description
technical field [0001] The present application relates to the field of building construction, and in particular to a construction method for repairing a drainage pipeline with a steel clasp. Background technique [0002] With the strengthening of urban infrastructure construction, a large number of municipal water supply and drainage pipelines have been built in the city. However, due to the different ages of the current pipeline laying, in addition to the damage of the pipelines constructed in the early stage, some new pipelines are also damaged due to poor local geological conditions and other reasons. Structural and functional damage occurred, seriously affecting the safe operation of urban drainage. [0003] The traditional pipeline repair process adopts excavation repair method to remove the defective pipe section and replace it with a new pipe section. It will increase the labor, material, and machinery costs required for ground restoration, etc., and the construction...
