The invention discloses a pipeline open excavation jacking construction method. The method comprises the steps that a pipeline groove is excavated; construction of a concrete pipe base foundation is conducted; and a plurality of construction areas are arranged on the concrete pipe base foundation. The jacking step of super-large-diameter pipelines in one construction area comprises the steps that a jacking device is arranged on the concrete pipe base foundation of the construction area, the super-large-diameter pipelines are placed on the two sides of the jacking device, and the two end faces of the jacking device abut against the end faces of the adjacent super-large-diameter pipelines correspondingly; then the super-large-diameter pipelines on the two sides are pushed through the jacking device, so that bell mouths and inserting mouths of the super-large-diameter pipelines on the two sides are in butt joint; and construction of the super-large-diameter pipelines in the remaining construction areas is conducted according to the jacking step of the super-large-diameter pipelines in one construction area. The problem that in the prior art, a pipeline construction method cannot meet the construction requirement of super-large-diameter pipelines is solved. Time and labor are saved, the construction cost is reduced, and the pipeline installation efficiency is greatly improved.
Description
technical field [0001] The application belongs to the technical field of pipeline construction, and in particular relates to a pipeline open-cut jacking construction method. Background technique [0002] With the rapid development of modern society and economy, the scale of urban construction is getting bigger and bigger. Urban municipal infrastructure is an important guarantee for the construction of urban material and spiritual civilization. Urban municipal infrastructure is the foundation of urban development and a key facility to continuously ensure the sustainable development of the city. As the urban pipeline network is paid more and more attention, there is an increasing need for systematic urban pipelines. Therefore, the construction of conventional municipal pipeline networks can no longer meet the needs of social development. The emergence of super-large-diameter pipelines has successfully solved the problem of insufficient flow in urban underground pipeline networ...
