Pipe-jacking boring machine with recyclable core parts

Abstract

The invention relates to a pipe-jacking boring machine with recyclable core parts, which comprises a shell, a cutter, a main shaft and a power box of the cutter, cutter bars, scrapers arranged on the cutter bars, a sludge inlet / outlet pipe, wherein the cylinder in the rear section of a cutter cone and the cylinder in the rear section of a shell cone divide the head part of a pipe-jacking machine into a soil chamber and a sludge chamber; the soil chamber is formed by a conical cutter and a shell cone; the conical cutter is arranged at the front end of the shell of the pipe-jacking machine, and a plurality of groups of cutter bars are arranged on the conical surface of the conical cutter symmetrically; the power box of the pipe-jacking boring machine is fixed on the shell by bolts in a flange form; the output shaft of the power box is connected with the cutter cone; a cutter bar twisted seat is welded on a cutter shaft sleeve of the cutter cone; cutter bars are fixed on the cutter bar twisted seat by pins and can swing on the cutter bar twisted seat through the pins; rubber fillers for preventing sludge blocks entering is filled into gaps between the cutter bars and the cutter cone; and the cutter bars are fixed on the cutter cone to prevent the cutter bars from leaning forwards and make the whole body of the cutter bars under stress.

Description

technical field [0001] The invention relates to a pipe jacking machine used in non-excavation engineering construction in the technical field of construction engineering, in particular to the manufacturing and assembling technology of the pipe jacking machine.

Problems solved by technology

[0002] At present, the common pipe jacking machine will get into trouble during the pipe jacking construction process, such as the construction of the river bottom or the bottom of the building and other places that cannot be excavated, and the pipe jacking machine will encounter insurmountable obstacles in front of it.

At this time, the pipe jacking machine can neither advance nor retreat, nor can it take out the pipe jacking machine from above.

Often a pipe jacking machine worth millions of dollars can only be placed underground, allowing it to rust and rot; a pipe jacking machine placed underground may also become an obstacle to other projects in the future

At the same time, the pipes that have been topped cannot be used normally, wasting a lot of manpower and material resources, especially losing the best construction location
