Abstract

The invention provides a high-pressure water cutter head which comprises a cutter head body, a hobbing cutter, a central rotary joint, a centralized valve block and a plurality of high-pressure water nozzles, the hobbing cutter is mounted on the cutter head body, and the central rotary joint is mounted on the back of the cutter head body; the centralized valve block is mounted on the cutter head body and is arranged along the radial direction of the cutter head body; the centralized valve block is communicated with the central rotary joint through a pipeline; and the plurality of high-pressure water sprayers are mounted on the centralized valve block. The technical problem that the matching effect of a high-pressure water spray head and hob rock breaking is poor is solved.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction equipment, in particular to a high-pressure water cutter head. Background technique [0002] In the field of underground engineering, shield tunneling method and TBM method are more and more widely used in construction. Shield machines and TBMs are special construction machines for tunneling, which have the functions of excavating and cutting soil, conveying sludge, and assembling tunnel linings. They have been widely used in tunnel projects such as subways, railways, highways, municipalities, and hydropower. [0003] Equipped with high-pressure water jet assisted rock-breaking technology on the TBM roadheader, it can improve the rock-breaking effect. On the TBM cutter head, the TBM hobs are usually arranged in a linear arrangement, a spiral arrangement, and the like. The space of the TBM cutter head is relatively compact. After the hobs are arranged, the high-pressu...
