Problems solved by technology

[0003] When the previous shield machine encounters a lot of irregular hard rock in the underground rock formation ahead, the cutter head of the shield machine wears a lot and needs to be pre-cut. However, the existing technology lacks an experimental platform for the pre-cutting of the shield machine

Abstract

The invention discloses a simulation experiment platform for combining high-pressure water jet and hob, which comprises a bottom plate, a plurality of support blocks are fixedly connected to the upper end of the bottom plate, and a support plate is fixedly connected to the upper end of the support block, and the support plate The upper end of the upper end is fixedly connected with a simulation test tube; the support plate is provided with a gap rotation mechanism, the output end of the gap rotation mechanism is connected with a bracket, and a telescopic drive mechanism is installed on the bracket, and the telescopic drive mechanism has two Output ends, one of which is connected to the water jet and the hob mounting plate, the other output end is connected to a support rod, the end of the support rod away from the telescopic drive mechanism is rotatably connected to a base plate, and the end of the base plate far away from the support rod is set There are simulated pressure plates. The outstanding feature of the present invention is that it is convenient to install high-pressure water jet equipment and traditional hob equipment on the water jet and hob mounting plate, and adopts high-pressure water jet technology for cutting, which is used to provide a simulation platform for the shield machine.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a simulation experiment platform for combining high-pressure water jets and hobs. Background technique [0002] The basic working principle of the shield machine is that a cylindrical steel component is pushed forward along the tunnel axis to excavate the soil. The shell of the cylindrical assembly is the shield, which acts as a temporary support for the excavated, unlined tunnel section, withstands the pressure of the surrounding soil and sometimes groundwater pressure and keeps it out. Excavation, soil dumping, lining and other operations are carried out under the cover of the shield. [0003] When the previous shield machine encounters a lot of irregular hard rock in the underground rock formation ahead, the cutter head of the shield machine will wear a lot, and pre-cutting is required. However, the existing technology lacks an experimental platform for pre-cutting of...
