Abstract

The invention discloses a pipe dragging structure with a built-in pipe for pipe jacking, which comprises: a casing and a built-in pipe. A plurality of bracket mounting plates are arranged at intervals in the longitudinal direction of the casing, and each of the bracket mounting plates is installed with A bracket, a sliding wheel device is installed on the bracket, a built-in tube is supported on the bracket, and the built-in tube can slide on the surface of the bracket, the bracket mounting plate is fixedly connected with the casing, and the bracket The mounting plate is fixedly connected with the bracket, which solves the technical problems in the prior art that the built-in pipes are damaged during the dragging process and the joints are easy to break.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a pulling structure and a pulling method for a built-in pipe of a pipe jacking casing. Background technique [0002] Slurry balance pipe jacking and horizontal directional drilling have been widely used in municipal pipeline engineering and other fields. Usually, reinforced concrete pipes, steel pipes, and PE pipes are used to lay pipes. In the construction environment of crossing underground soil layers, structures, and rivers, construction methods are usually used. Pipe jacking for mud-water balance, horizontal directional drilling, especially when traversing corrosive formations or where maintenance is required. In the field of trenchless technology, pipe jacking is often used in pipeline construction. During construction, it is often necessary to lay pipes inside casings. The casings generally use reinforced concrete pipes and steel pipes, and the inner pipes...
