Embodiment Construction
[0019] The present invention will be further described in conjunction with specific embodiment now, and following embodiment is intended to illustrate the present invention rather than further limiting the present invention.
[0020] The wear test and prediction method of the cutting tool of the tunneling equipment in the soft soil environment, the method includes the following steps carried out in sequence:
[0021] First, prepare and install the test device. The test device includes a test chamber, a soil sample, a drive shaft with a blade-shaped cutter, an upper end cover, and a drive unit. Indoors, soil samples are collected from the construction site. The lower part of the test chamber is soil samples, and the upper part is pressurized gas. The cutter is inserted into the soil samples, and the upper end cover is fixedly connected with the upper end of the cylinder of the test chamber. A two-way sealing device that can withstand high pressure is arranged between the bodies...
