Description

Ultra-high pressure water distributor of tunnel boring machine

Technical Field

The invention belongs to the technical field of abrasive water jet tunneling machine components, and particularly relates to an ultrahigh-pressure water distributor of a tunneling machine.

Background

With the development of the existing national infrastructure, the limitations of the existing shield tunneling machine and TBM (full-face hard rock tunnel boring machine) are more and more obvious, and the requirements of high-speed and high-efficiency infrastructure cannot be met, for example, the construction of railways and subways is required to be carried out by detouring when super-hard rocks and hard rocks are encountered in the past, the construction period is influenced, and resources are wasted. If the underground long foundation building pile is longer than 25 meters, the pile can be blocked, the pile is difficult to cut, the pile is difficult to bypass, the construction period is influenced, and resources are wasted.

The cutter head, the cutter and the equipment are expensive in cost, the technology of abrasive water jet is low in cost of water and sand, more environment-friendly and convenient to obtain materials, and the construction task can be completed by reducing detour or not detour.

The cutter head of the tunneling machine is in rotary tunneling, sand, gas and water are supplied through pipelines, and the continuous rotation inevitably causes knotting and twisting off, so that the technical problem of how to supply the sand, the gas and the water to the rotary cutter head is solved. When water is distributed in front of the cutter head, the prior art adopts a water supply pipe which is connected with a plurality of outlet pipes in series, the connection volume is large, and the energy loss is large in the water flow flowing process.

The water cutter head structure of the existing excavator (shield machine and TBM full-face hard rock tunnel boring machine) is fragile and easy to damage, and the edge angle of a cut object cannot be cut when the cutter head cuts.
