A construction structure for pipe jacking of municipal engineering pipelines

Abstract

The invention discloses a pipe jacking construction structure for municipal engineering pipelines, comprising a base, a side surface of the base is provided with a meshing plate parallel to itself, and a threaded rod extending to the top of the base runs through the side of the meshing plate. The right side of the threaded rod is rotatably connected with a rack that is perpendicular to the base. Both ends of the rack are engaged with gears that are rotatably connected to the base. The surface of the gear is provided with a first movable plate with a length greater than its own radius. The top of the first movable plate is rotatably connected with a second movable plate, which is a pipe jacking construction structure for municipal engineering pipelines, and has strong practicability. When in use, the inner support ring can be controlled to contact the soil to prevent the soil from being processed by the equipment. Falling affects construction. If the position of the pipeline is deviated after it is put down, the straightening plate can be controlled by the straightening mechanism to straighten it. When the pipeline is pushed into the soil, in order to prevent it from being displaced due to the force, the clamping ring can be controlled by the fixing mechanism. Limit penetration.

Description

technical field [0001] The invention relates to the field of pipeline construction, in particular to a pipe jacking construction structure for municipal engineering pipelines. Background technique [0002] With the development and construction of the economy, the number of water conservancy and hydropower projects in my country is increasing, and the related technologies have become more and more mature. Among the many construction technologies, the application of pipe jacking construction can significantly promote the economic benefits of the project. It can play a very important role in engineering construction. Pipe jacking construction is a non-excavation construction method, which is a pipeline burial construction technology with no or less excavation. Due to the jacking force generated by the jacking equipment, the friction between the pipeline and the surrounding soil is overcome, the pipeline is jacked into the soil according to the designed slope, and the earth is tra...
