Abstract

The invention discloses a pipe jacking sleeve built-in pipeline dragging structure. The structure involves a sleeve and a built-in pipe, wherein a plurality of bracket mounting plates are arranged atintervals in the sleeve in the length direction, a bracket is arranged on each bracket mounting plate, a sliding wheel device is arranged on each bracket, the built-in pipe is supported on the brackets, the built-in pipe can slide on the surfaces of the brackets, the bracket mounting plates are fixedly connected with the sleeve, and the bracket mounting plates are fixedly connected with the brackets. The technical problems that in the prior art, in the dragging process, the built-in pipe is damaged and a joint is prone to break are solved.

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...
