Abstract

The invention belongs to the technical field of pipeline installation, and particularly relates to a construction method for an underground small-space corrugated pipe to penetrate through a pipeline through a rail tackle. The construction method comprises the following steps that 1, an outer layer pipeline is jacked, and pipe jacking construction of the outer layer pipeline is completed; 2, a track is laid in the outer-layer pipeline; 3, according to the size of the laid track, a plurality of track pulleys are manufactured; 4, a plurality of rail pulleys are evenly arranged at the bottom of the corrugated pipe, the rail pulleys and the corrugated pipe are fixed together, and then the rail pulleys provided with the corrugated pipe are placed on the rails; and 5, the corrugated pipe penetrates through the outer-layer pipeline. The corrugated pipe penetrates through the outer-layer pipeline by adopting the rail pulley, so that the installation and debugging time of equipment is greatly saved, the construction cost is saved, the construction difficulty is reduced, the construction efficiency is improved, and the construction investment is reduced; the construction period can be saved and the action area is reduced.

Description

technical field [0001] The invention belongs to the technical field of pipeline installation, and in particular relates to a construction method for a bellows in a small underground space to pass through the pipeline by using a rail pulley. Background technique [0002] Pipe jacking construction is a popular underground pipeline construction method at present. It does not need to excavate the surface layer. The noise during construction is much lower than that of slotted pipelines, and it has little impact on ground settlement. In the case of deep pipeline buried The construction cost is better than the construction method of slotting and laying pipelines. At present, some pipelines have two layers of pipes with different diameters inside and outside to form casings to ensure the overall quality of the pipeline. In some specific cases, the space between the launching shaft and the receiving shaft on both sides of the pipe jacking is relatively narrow, and it is inconvenient...
